How do triglycerides found in animals differ from those found in plants.

Answers

Answer:

Lipids include a diverse group of compounds that are largely nonpolar ... Lipids also provide insulation from the environment for plants and animals (Figure 3.3.1) . ... A fat may contain similar or different fatty acids attached to glycerol. ... If hydrogens are present in the same plane, it is referred to as a cis fat; ...

Explanation:

The triglycerides found in animals are solids while the triglycerides found in plants are generally liquids.

What do you mean by Triglycerides?

Triglycerides may be defined as a type of ester that is considerably derived from glycerol and three fatty acids. They are the main constituents of body fat in humans and other vertebrates, as well as vegetable fat.

The Triglycerides that are found in animals are typically solid or semisolid. They have the same appearance and properties at room temperature and are classified as fats. Those triglycerides that are liquid are called oils and are derived chiefly from plants.

In animals, the carbon atoms in the fatty acids are saturated with hydrogen atoms. This permits them to lie straight and the molecules will pack neatly into a solid arrangement. In plants, missing hydrogen atoms cause kinks in the fatty acids which make the structure loosely compact, and thus they are liquids.

Therefore, the triglycerides found in animals are solids while the triglycerides found in plants are generally liquids.

Urea diffused in all regions of the filter during countercurrent flow.
Using what you know about the sizes of urea and potassium, which graph shows what would happen to potassium
during countercurrent flow?
Diffuse

Answers

Consider a scenario in which urea is diffusing from an area of higher concentration to a region of lower concentration while the blood and dialysate are moving in the same direction.

Diffusion therefore occurs throughout the entire filter. The dialysate's urea concentration is shown by the blue line, while the blood's urea concentration is shown by the red line.

What is diffusion?

A substance diffuses when it moves from a region of high concentration to one of lower concentration. When particles in liquids and gases randomly collide and disperse, diffusion takes place. For living things, diffusion is a crucial mechanism because it governs how molecules enter and exit cells.

What distinguishes osmosis from diffusion?

Diffusion permits both solvent and solute molecules to move freely, whereas osmosis only permits solvent molecules to do so.

Through mitosis, somatic and germ cells divide to produce two daughter diploid cells that are identical to the parental one. A) This model results in two identical daughter cells. B) This model shows asexual reproduction. E) This model shows mitosis.

What is mitosis?

Mitosis is a cell division process through which a diploid somatic cell (2n), produces two identical daughter diploid cells (2n).

During mitosis, the whole-cell first suffers duplication of its content and then it separates. Mitosis occurs in somatic cells and in germ cells.

In this example, we can see

One cell with two chromosomes (step 1). This cell duplicates its content, and now each chromosome is composed of two chromatid sister (step 2). Chromosomes move to the equatorial plane where they align (step 3) and then each chromatid separates from the sister chromatid and moves foward one of the cell poles (step 4). The cell divides and the two resulting cells have two chromosomes, just as the parental cell (step 5)

A) This model results in two identical daughter cells.

B) This model shows asexual reproduction.

E) This model shows mitosis.

what is the resting phase of the cell cycle called?

A. Prometaphase
B. Mitosis
C. Interphase

Answers

The resting phase of the cell cycle is called interphase.

Interphase is a critical stage in the cell cycle during which the cell prepares for division by going through different activities such as growth, DNA replication, and protein and organelle production. It is the longest phase of the cell cycle and is separated into three subphases: G1 (Gap 1), S (Synthesis), and G2 (Gap 2).

The cell develops in size, synthesises RNA and proteins, and performs its regular duties during the G1 phase. The cell enters the S phase after passing through the G1 checkpoint. The DNA of the cell is reproduced during the S phase, resulting in the production of two identical copies of each chromosome.

This ensures that during cell division, each daughter cell receives a complete set of genetic material. The cell enters the G2 phase after DNA replication, where it continues to expand and prepares for mitosis.

Interphase is not a real resting phase because the cell is actively engaged in multiple cellular functions. However, because the cell is not visibly dividing at this period, it is commonly referred to as the resting phase.

Two pea plants produce the following offspring:225 tall with purple flowers250 short with white flowers237 tall with white flowers241 short with purple flowersWhich of the following parental pairs is more likely - two plants heterozygous for both genes, or one heterozygous for both genes and one homozygous recessive for both genes? Explain your answer.

Answers

Even without knowing which allele is dominant or recessive, we can understand the likely ancestors by analyzing the proportion among the offspring.

A crossing between two heterozygous will result in a 9/3/3/1 proportion (among 16 possible results), as follows:

- 9 will be dominant for both traits

- 3 will be dominant for the size and recessive for the color

- 3 will be recessive for the size and dominant for the color

- 1 will be recessive for both traits

But in a crossing between one heterozygous and one recessive, it will result in a 4/4/4/4 proportion (among 16 possible results), as follows:

- 4 will be dominant for both traits

- 4 will be dominant for the size and recessive for the color

- 4 will be recessive for the size and dominant for the color

- 4 will be recessive for both traits

Therefore, the option that fits better is the second option, as the result we see is closer to the 4/4/4/4 proportion. The correct answer is one heterozygous for both genes and one homozygous recessive for both genes.

The traits of all 4 characters will show one homozygous and one heterozygous allele for all characters. The punnett square has a ratio of 9/3/3/1. The correct answer is last 2 options.

What is punnett square ?

The punnett square is the square where there are crosses between the alleles having different genes. It is the calculated estimated result of the species.

Tall with purple flowers having traits of both when segregated before expression, short with white flowers, tall white flowers and short purple flowers when combined all together will either have dominant traits for one or the recessive.

The dominant can be homozygous or heterozygous, recessive can be homozygous and heterozygous as well. Either dominant or recessive it will have both homo as well as hetero conditions.

Therefore, the plants have both the homozygous as well as heterozygous recessive or dominant for both depending on the type of condition present in parents.

What are the unique characteristics of the garden pea that allowed George Mendel (the father of genetics) to study them successfully?

Answers

Mendel chose the pea, one of many species, to study because the plants and seeds exhibit a variety of distinctive characteristics that appear in two readily recognizable forms (e.g., seed shape is round or wrinkled; plant height is tall or short).

George Mendel, the father of genetics, chose pea plants for his genetic experiments for a variety of reasons, including

• Garden plants are simple to grow.

• Pea plant blooms are hermaphrodites, which means they exhibit traits of both sexes.

• Plants of the pure breed can be easily obtained through self-fertilization.

• Pea plants produce more quickly than other plants.

• They have a high rate of survival and remarkable disease resistance.

Gregor Mendel's research on pea plants led him to the fundamental ideas of inheritance. He came to the idea that genes are passed down from each parent as unique, paired units.

Mendel observed how parental genes separated and if they showed up as dominant or recessive qualities in the offspring. Gregor Mendel experimented with hybridization on about 29,000 pea plants. Mendel found that peas were the perfect subject since they possessed seven easily observable features that he could control. He set up two settings before starting his pea studies.

As a result, we can infer that Mendel chose the pea as the species to study out of all the others since it has a diversity of distinguishing traits in both its plants and seeds.

Answers

The effect of different coloured light waves on the growth of pea plants was to be observed by a botanist. The same number of seeds were put in three plants with the same type of pots and the same type of soil and every day, they were given the same amount of water. If one pot is placed in a dark windowless closet, the second is placed on the windowsill and the third is placed under a lamp with a green bulb. The variable factor, in this case, will be the colour of light.

Why is light important for plants?

Plants require light for the process of photosynthesis. In the process of photosynthesis, the light is trapped by the chlorophyll pigment present in the mesophyll cells of the leaves of the plants.

The light energy is trapped and converted into chemical energy. This is then used for the hydrolysis of water and the reduction of carbon dioxide. These processes then result in the formation of glucose.

Therefore, the plant that gets abundant sunlight on the windowsill will grow better than the plant placed under a lamp and the plant placed under the lamp will grow better than the pot placed in a dark closet.

What is the origin of the term cell in biology?

Answers

Answer:

The Origins Of The Word 'Cell' In the 1660s, Robert Hooke looked through a primitive microscope at a thinly cut piece of cork. He saw a series of walled boxes that reminded him of the tiny rooms, or cellula, occupied by monks. Medical historian Dr. Howard Markel discusses Hooke's coining of the word "cell."

Dr. Robert Hazen has worked to develop a hypothesis that explains
the origin of life on Earth. His work has focused on hydrothermal vents, which are cracks in the ocean floor. Water heated by molten rock beneath the crust escapes from these vents at very high temperatures, producing hot, high-pressure environments at the vents on the ocean floor.
In order to provide evidence that these vents may be areas where life originated, which of the following states a null hypothesis Hazen might have used to begin his research?
(A) Organic molecules were transported to the hydrothermal vents via a meteorite, thereby seeding them with precursors for more complex molecules.
(B) The temperatures and pressures found in hydrothermal vents resemble conditions described in currently accepted origins of life hypotheses.
(C) Organic waste sinking to the ocean floor would have used the unique hot water environment as an energy source to begin manufacturing food.
(D) Chemosynthetic organisms can best develop in the hydrothermal environment, manufacturing nutrients for other living things to feed on.

Answers

Answer:

(B) The temperatures and pressures found in hydrothermal vents resemble conditions described in currently accepted origins of life hypotheses

Explanation:

We are told that Dr. Hazen wants to develop a hypothesis that explains

the origin of life on Earth.

Now, he focused on hydrothermal vents. That Water heated by molten rock beneath the crust escapes from these vents at very high temperatures, producing hot, high-pressure environments at the vents on the ocean floor.

This means the null hypothesis will be temperatures and pressures found in this initial condition he described while any other different from it will be the alternative hypothesis.

Looking at all the given options and comparing with the initial hypothesis conditions in the question, the correct answer is option B.

The origin of life can be seen as the natural process in which the origin of living things happen through non-living matter or smaller organic compound.

The null hypothesis is:

(B) The temperatures and pressures found in hydrothermal vents matches the conditions described in currently accepted origins of life hypotheses.

The null hypothesis for  Dr. Robert Hazen hypothesisThe hypothesis says that hydrothermal vents are cracks in the ocean floor.

It also states that there were high temperatures and high pressure environment.

Thus, the option (B) The temperatures and pressures found in hydrothermal vents matches the conditions described in currently accepted origins of life hypotheses is the best null hypothesis for Dr. hazen to begin his research.

Inquiry-based pedagogy is a teaching approach that promotes active learning and critical thinking through inquiry and exploration. One relevant example of inquiry-based pedagogy is a science classroom where students are encouraged to design and conduct their own experiments. Instead of simply following instructions, students formulate research questions, develop hypotheses, plan and execute experiments, collect and analyze data, and draw conclusions. For instance, students may investigate the effect of different variables on plant growth by manipulating factors like light, water, or soil composition. This approach allows students to engage in authentic scientific practices, develop problem-solving skills, and gain a deeper understanding of the scientific method. By actively participating in their learning process, students develop a sense of ownership and become more engaged, fostering a love for learning and nurturing their ability to explore and discover knowledge independently.
