C. Sedimentary

Explanation:

Answer:

Ribose and deoxyribose are monosaccharides or simple sugars. They are al and undergo phosphorylation to form deoxyribonucleotides and ribonucleotides. They are of great biological importance that helps in the formation of a blueprint of an organism that is passed on to generations.

The nucleotides act as the building blocks of nucleic acids and help them to carry genetic information. Pentose sugar for RNA is ribose with 5 carbon atoms. Pentose sugar for DNA is deoxyribose.

Ribose was discovered by Emil Fischer and Oskar Pilot in the year 1891. Deoxyribose was discovered by Phoebus Leven in the year 1929. Some differences between deoxyribose and ribose based on structure, IUPAC name, molar mass, chemical formula, etc., are given below.

Answer:

Major Steps of Glycolysis:

Glycolysis involves a sequence of steps that can be grouped into three important reactions: phosphorylation of glucose, splitting of the six-carbon molecule into two three-carbon molecules, and the energy harvesting reactions.

Answer and Explanation: 1

The products of Glycolysis are as follows:

Pyruvic Acid

Two molecules of NADH (Nicotinamide Adenine Dinucleotide)

Two molecules of ATP (Adenosine Triphosphate)

Although 4 ATP are produced, 2 ATP are spent during phosphorylation of glucose (conversion of glucose to fructose 1,6-bisphosphate), thus, there is a net gain of only 2 ATP molecules.

Answer:

distal and proximal

Explanation:

The two orientation terms that have opposite meanings in humans would be distal and proximal.

While distal means for a cell, tissue, or organ to be away from a particular point or region, proximal means for a cell, tissue, or organ to be towards a particular point or region. In simpler words, distal means fro while proximal mean to - just like work and opposite.

The prefix "gen-" in "generation" implies the act of beginning or bringing forth something new, marking a departure from what existed before.

The prefix "gen-" does not specifically mean "begin," but rather derives from the Greek word "genēsis," which translates to "origin" or "creation." In the context of the key term "generation," the prefix "gen-" conveys the notion of creating or producing something new.

When we refer to "generation," we often think of a group of individuals born and raised during a particular period. However, the concept of generation extends beyond human demographics. It encompasses the idea of a collective creation or production of something that arises or evolves within a specific time frame.

In the broader sense, generation implies the development, formation, or emergence of something novel, whether it be ideas, technologies, energy sources, or social movements. It captures the essence of progress and the continuous cycle of renewal and innovation.

Answer:

Both studies support the concept that species operate within a narrow optimum temperature range and are coupled to enzymatic activity.

Explanation:

The studies shown in the question above started from the same concept to establish the scientific experiment and had the same objective related to the investigation as temperature changes in the environment where these organisms live influences the enzymatic activity and, therefore, the functioning of their organism, being able to including modifying the environment around them. In summary, we can say that the studies sought to support the concept that species operate within a narrow range of optimal temperature and are coupled with enzymatic activity.

Answer:

This is actually a case of additive effect that means, it doesn't matter which allele is dominant which is recessive. Here what really matter is the total number of dominant and recessive alleles.

Offspring with_

All 6 dominant allele possess 100% sugar content.

any 5 dominant alleles  possess 90% sugar content.

Any 4 dominant alleles  possess 80% sugar content.

Any 3 dominant alleles  possess 70% sugar content.

Any 2 dominant alleles  possess 60% sugar content.

Any 1 dominant allele  possess 50% sugar content.

Zero dominant allele (aabbcc)  possess 40% sugar content.

Hence by this concept we can easily find the percentage of sugar content of any offspring.

what is the probability that an F2 plant will produce fruit with that sugar content?

a. 70% - 17/64. (all Blue coloured offsprings)

b. 50% - 5/64. (all green cloured offsprings)

The population density of the 900 sheep in the given plot of land is 150 sheep per square kilometer.

The population density of 900 sheep in a plot of land that is 3.00 km by 2.00 km can be calculated by dividing the total number of sheep by the area of the land.

First, we need to calculate the area of the land. The area can be found by multiplying the length and width of the plot of land:

Area = length × width = 3.00 km × 2.00 km = 6.00 km²

Next, we divide the total number of sheep by the area to calculate the population density:

Population Density = Total number of sheep / Area = 900 sheep / 6.00 km²

Performing the calculation, we find:

Population Density = 150 sheep/km²

Therefore, the population density of the 900 sheep in the given plot of land is 150 sheep per square kilometer.

Population density is a measure of the number of individuals (in this case, sheep) per unit area. By dividing the total number of sheep by the area of the land, we obtain the population density in terms of sheep per square kilometer. In this case, the population density is 150 sheep/km², indicating that there are, on average, 150 sheep within each square kilometer of the land.

a) The seed of a pea flower is formed from the ovule, which is located in the ovary of the flower.

b) Part Z in the drawing represents the ovary, which contains the developing seed (pea) within the pea pod.

c) The plant exhibits this twisting and splitting behavior of the pea pod to facilitate seed dispersal. There are two main reasons for this:

  1. Wind dispersal: By drying out and twisting, the pea pod creates tension, which is suddenly released when it splits open. This mechanism allows the seeds to be forcefully projected away from the parent plant, increasing the chances of wind carrying them to new locations for germination.

  2. Animal dispersal: The sudden splitting and flicking of the pea pod can attract the attention of animals. The movement and sound generated by the splitting pod may entice animals to investigate, and in the process, some seeds may get attached to their fur or feathers. These animals can then carry the seeds to different locations, aiding in dispersal.

d) One other way in which a plant can move its seeds away from the parent is through animal-mediated dispersal. Some plants have adaptations that entice animals to consume their fruits, which contain seeds. The animals eat the fruit and subsequently excrete the seeds in a different location, enabling seed dispersal away from the parent plant. This method is often used by plants that produce fleshy and nutritious fruits to attract animals as seed dispersers, such as berries being eaten by birds.

The step 3 exercise tells us that a hybrid male individual and a hybrid female individual (F1) mate with each other and have offspring. In this context, by the term hybrid, we know that the exercise refers to the organisms' genotype having two different alleles for the fur color (in this case we can use B for black fur color, and b for white, for example), what would be Bb. We can complete then the Punnet squares as follows:

Here we can see the information that will be useful to do the other square, which is like the following:

We can compare these two probabilities by saying that for 3 organisms with black fur, there would be 1 with white fur, having a ratio of 3:1. This also can be approached by saying that the predicted percentage usually reflects the simulated numbers and the simulated percentages, since although there can be a lower or higher ratio, it is still near that value: 3:1.

The gas produced in the burning of fossil fuels that has been most closely linked to rising atmospheric temperatures is carbon dioxide. Option D

As a byproduct of combustion when fossil fuels like coal, oil, and natural gas are used to produce energy, carbon dioxide is discharged into the atmosphere.

As a greenhouse gas, carbon dioxide absorbs heat from the sun inside the Earth's atmosphere, creating the greenhouse effect, which causes global warming. The Earth's natural greenhouse effect, which keeps the globe warm enough to support life, is caused by this phenomena.
