Answer:

The tenet of cell theory that BEST serves as a basis for this type of biotechnology is that all living things are composed of cells.

Cell theory states that all living things are composed of one or more cells and that the cell is the basic unit of life. In biotechnology, genes that code for a specific protein can be inserted into bacterial plasmids, which are small circular pieces of DNA found in bacteria, and then the plasmids are used to transform cells. The transformed cells can then produce the desired protein. This process is based on the understanding that all living things are composed of cells and that the genetic information necessary to produce specific proteins is contained within the cell's DNA. Without this understanding of the basic unit of life being the cell, it would not be possible to create transgenic bacteria to synthesize human proteins for medical use.

Explanation:

When the cell is at the resting membrane potential (-70 mv), both the chemical and electrical forces are channeled into the cell.

Define resting membrane potential

The electrical potential difference across the plasma membrane of a cell during its non-excited condition is referred to as the resting membrane potential of the cell. The value of the electrical potential difference inside a cell compared to the extracellular environment is traditionally used to describe the electrical potential difference across a cell membrane.

Any ion's equilibrium potential value is determined by the gradient of that ion's content across the membrane. The force of the concentration gradient and the equilibrium potential would both be zero if the concentrations on the two sides were identical.

Answer:

The evidence is not enough to rule him out as the baby's father.

Explanation:

If one parent has Type A blood, and the other has Type B, the baby can be either Type A, B, AB, or O. There are 3 types of blood alleles; A, B, and O. A and B are codominant, meaning that they are equally dominant. Both the A and the B will dominate the O, but if both are present together, they become AB. If the father's blood consists of a B and an O, then it's entirely possible that he gave the O and the Mother gave an A. The A would dominate the O, meaning that even though the allele would be read as AO, the blood type would be A. But this argument only works if the father is BO. If the father was BB, then it would be impossible for the baby to have Type A blood.

The organisms that feed on dead and decaying matter are called Saprotrophs.

An organism that feeds on dead and decaying organic matter is called a saprotroph. These organisms are heterotrophic, which means that they obtain their food from other sources. They are important in the ecosystem because they break down dead organic matter and recycle it back into the soil, making nutrients available to other living organisms

Answer:

A. Saprotrophs

Explanation:

Saprotrophs are organisms that obtain their nutrients by feeding on dead and decaying matter. They play a crucial role in the ecosystem by decomposing organic material and recycling nutrients back into the environment.

These organisms secrete enzymes that break down complex organic compounds into simpler substances, such as sugars and amino acids, which they can absorb and utilize for their own growth and energy needs. Examples of saprotrophs include fungi (such as mushrooms and molds) and certain bacteria.

Unlike autotrophs, which can produce their own food through photosynthesis or chemosynthesis, saprotrophs rely on external sources of organic matter for their nutrition. They actively decompose dead plants, animals, and other organic materials, aiding in the process of nutrient recycling and decomposition.

Heterotrophs, on the other hand, are a broader category of organisms that obtain their nutrients by consuming other living or dead organisms. This includes saprotrophs, as well as other types of organisms such as herbivores, carnivores, and omnivores.

Parasites, meanwhile, are organisms that live in or on other organisms, known as hosts, and obtain their nutrients from the host while causing harm or damage to it. Unlike saprotrophs, parasites typically rely on a living host for their sustenance rather than feeding on dead and decaying matter.

The best summary of the outcome of Redi's experiment is that the experiment provided evidence against spontaneous generation by demonstrating that maggots do not spontaneously generate from decaying meat when it is isolated from flies.

Francesco Redi conducted an experiment in the 17th century to challenge the prevailing belief in spontaneous generation, which proposed that living organisms could arise spontaneously from non-living matter.

In his experiment, Redi set up two groups of jars containing meat. One group was covered with gauze to prevent flies from accessing the meat, while the other group was left uncovered.

Over time, Redi observed that maggots appeared only in the uncovered jars where flies had access to the meat, while the covered jars remained free of maggots.

This led Redi to conclude that maggots were the offspring of flies and did not arise spontaneously from the meat.

His experiment provided empirical evidence against the theory of spontaneous generation and contributed to the development of the concept of biogenesis, which states that living organisms come from pre-existing living organisms.

The third trophic level is made up of prairie dogs that get their matter and energy from the grasses (option d).

The energy pyramid depicted in the image illustrates the flow of energy through an ecosystem. In an energy pyramid, each level represents a trophic level, indicating the position of organisms in a food chain. The pyramid narrows as it ascends, indicating the decrease in available energy at higher trophic levels.

In this specific pyramid, the lowest trophic level is occupied by the grass. This makes sense because grass is a producer that captures energy from the sun through photosynthesis. As a result, it possesses the most energy within the ecosystem.

Moving up the pyramid, the second trophic level is occupied by the prairie dogs. They are herbivores that primarily consume grass for their energy needs. This demonstrates that the prairie dogs acquire their matter and energy from the grasses, supporting option D.

The third trophic level contains the coyotes, which are tertiary consumers. Tertiary consumers feed on other consumers, not producers. Therefore, option A is incorrect since vultures, not coyotes, are tertiary consumers in this ecosystem.

Option B is also incorrect because the coyotes do not obtain their energy from other coyotes located in the third trophic level. They acquire their energy indirectly from the grasses through the prairie dogs.

Finally, option C is incorrect as it states that the grasses' trophic level has the most energy. While the grasses are indeed the primary producers and possess the most energy, not all of that energy moves to the second trophic level.

Thus, the correct statement supported by the ecological pyramid is option D: The third trophic level is made up of prairie dogs that get their matter and energy from the grasses.

There are various layers that make up the atmosphere, and each has distinct properties and functions. Both weather generation and energy transmission take place in the troposphere, which is closest to the Earth's surface.

The stratosphere shields the Earth from damaging UV radiation along with the ozone layer. Most auroras happen in the mesosphere, where meteors burn up. Modern technology is dependent on the thermosphere, where the majority of the Earth's satellites orbit and where communication signals are sent.

The dynamics of the atmosphere and its interactions with the hydrosphere and lithosphere are better understood thanks to these layers. Foreseeing and minimising environmental problems like climate change and preserving our world, it is essential to understand the significance of each layer.

According to the table that represents the genetic code, the amino acid sequence that corresponds with the mRNA sequence GAA UUU ACG AAA is glutamic acid-phenylalanine-threonine-lysine (Option D).

The genetic code is the information contained in the DNA sequence, which is sued to produce a given sequence of amino acids in a protein during translation. The triplets of nuclotides or codons in DNA are used to generate the proteins, e.g., the GAA  codon is used to add glutamic acid.

The genetic code links a given sequence of amino acids during the translation in the ribosome with specific codons in the mRNA sequence, which are complementary to the DNA sequence obtained during translation since transcription and translation are cellular processes that are interrelated and dependent on each other to produce a protein.

Therefore, we can conclude that the sequence glutamic acid - phenylalanine - threonine - lysine is encoded by using the mRNA sequence GAA UUU ACG AAA (Option D).

Living things use structural strategies and behavioral strategies that increase their chances of reproduction.

Living things do so to reach the reproduction goal that is to pass genes on to offspring. For example: the pouch of a kangaroo, a frog croaking a mating call,  and colorful petals of flower etcetera helps in increasing mating chances so that their genes can be followed to the generation.

The phenotypic ratio of the cross is as follows: 3 red antennas: 1 white antenna

For question 2, the phenotypic ratio of the F2 generation is: 3 black-eyed: 1 orange-eyed

QUESTION 1

According to the first question, a gene coding for antenna color in butterflies is involved. Red antennas (“R”) is dominant to white antennas (“r”). Hence, a butterfly with genotype "Rr" will be phenotypically red.

According to this question, If both parents are heterozygous for red antennas i.e. Rr (red antenna) × Rr (red antenna), the following gametes will be produced: R and r. Using these gametes in a punnet square (see attached image), the following phenotypic ratio of offspring is produced:

3 RED ANTENNAS (RR, Rr, Rr) : 1 WHITE ANTENNA (rr)

2. In the second question, all the offspring of a cross between a black-eyed mendelien (BB) and an orange-eyed mendelien (bb) have black eyes (Bb). In a cross between two F1 black-eyed mendeliens i.e. Bb × Bb, the following proportion of offspring is produced:

BB, Bb, Bb, bb

Transformation and transduction are two of the three processes bacteria uses in genetic recombination (the third being conjugation). As rightly stated in the question, both processes establish that DNA is the genetic material of most living organisms and they both involve transfer and expression of DNA from cell to cell.

However, both processes are different in the way they get the foreign DNA into the bacteria cell.
