These two plants look so similar if their common ancestor was very distant because it shows analogous evolution which is the evolutionary process in which organisms exhibit similarities in function but differ in the evolutionary origins.

The term analogous is derived from  Greek analogos, which means “according to a proper ratio or proportion".

Analogous evolution is the type of evolution having similarities in function but have different evolutionary origins. In analogous evolution, different species with different evolutionary lines use their biological structures for the same purpose. This type of evolution is called as convergent evolution.

The structure evolved independently in different individuals which serve the same function. Examples of Analogous evolution, Wings of Birds and insects.

Thus, these two plants look so similar if their common ancestor was very distant because it shows analogous evolution which is the evolutionary process in which organisms exhibit similarities in function but differ in the evolutionary origins.

In the Ames Test, the appearance of his+ revertants in the presence of a non-mutagenic control compound indicates that some of the reversion mutations are not caused by the mutagen being tested.

The Ames test is a widely used method for the evaluation of mutagenicity in which the reverse mutation in the histidine-requiring Salmonella strain is used to measure the genetic changes that occur due to mutagenic agents such as carcinogens.  The test has a high level of sensitivity and can detect very low levels of mutagenic substances.

The Ames test can detect mutations that alter the expression of genes that are important for the maintenance of the normal metabolic pathways of the cells. For instance, if a mutagenic substance is present, it can cause mutations in the cells that can result in his- phenotype which can be reversed if the mutagen is removed. This is the basic principle behind the Ames test.

In this context, the appearance of his+ revertants in the presence of a non-mutagenic control compound indicates that some of the reversion mutations are not caused by the mutagen being tested, but rather due to the natural occurrence of mutations in the cells. In other words, the control compound is not mutagenic, but the cells can still undergo spontaneous mutations that can lead to the reversal of his- phenotype. Therefore, the results of the Ames test must be interpreted carefully, and the appearance of revertants must be confirmed by other means such as sequencing of the genes. 

Therefore, it is concluded that in the Ames Test, the appearance of his+ revertants in the presence of a non-mutagenic control compound indicates that some of the reversion mutations are not caused by the mutagen being tested.

Answer:

B.) A gamete needs only half the number of chromosomes because two gametes join together.

Explanation:

The correct answer is B. Eutrophication is a process where excessive nutrients such as nitrogen and phosphorus enter a body of water, leading to an increase in the growth of algae and other photosynthetic microorganisms.

This can result in the formation of harmful algal blooms and a decrease in water clarity. However, eutrophication does not necessarily lower the oxygen content of the water, kill off existing bacteria, or promote heterotrophic aerobic respiration. In fact, eutrophication can lead to an initial increase in oxygen production due to the high levels of photosynthetic activity. Over time, however, as the excess algae and other microorganisms die and decompose, the process of decomposition can consume oxygen and eventually lead to lower oxygen levels in the water.

Step 1 of Mendel's garden pea experiment focused on establishing purebred, or true-breeding, pea plants.

By allowing each variety of garden pea to self-pollinate for several generations, Mendel ensured the plants would produce offspring with consistent traits. This process led to the creation of stable, homozygous strains, where both alleles for a particular characteristic were identical in the parent plant.

Mendel's experiment aimed to understand the fundamental principles of inheritance, and these true-breeding plants served as the foundation for his subsequent research. By creating a controlled, predictable population of pea plants, Mendel could study how specific traits were passed from one generation to the next, leading to the discovery of his famous laws of inheritance.

In summary, the first step of Mendel's garden pea experiment, which involved self-pollinating various pea plant varieties for several generations, produced purebred or true-breeding plants. These plants had consistent traits and served as the basis for Mendel's investigation into the principles of inheritance, ultimately revolutionizing the field of genetics.

After being produced by mitosis, newly formed cells must copy the chromosomes before they can be fully functioning cells in an organism. Option B is the correct answer.

Mitosis is the process of cell division that produces two identical daughter cells from a single parent cell. During mitosis, the parent cell's chromosomes are replicated, and each daughter cell receives a complete set of chromosomes. However, before the newly formed cells can become fully functioning cells, they need to ensure that each chromosome is copied accurately.

This process occurs during the S phase of the cell cycle, which takes place before mitosis. By copying the chromosomes, the newly formed cells ensure that each daughter cell has a complete and identical set of genetic information, allowing them to function properly in the organism.

Therefore, copying the chromosomes is a crucial step that newly formed cells must undergo before they can be fully functioning cells in an organism (Option B).

The frequency of the a2 allele at equilibrium is p = 0.485. In the new environment, the frequency of the a2 allele in the adults after one generation of selection will be p = 0.472.


a. To find the frequency of the a2 allele at equilibrium, we can use the equation p² + 2pq + q² = 1, where p is the frequency of the a1 allele and q is the frequency of the a2 allele.

We can also use the equation for the average fitness of the population, W = p²w11 + 2pqw12 + q²w22, where w11, w12, and w22 are the relative fitnesses of the three genotypes. Plugging in the given values for the relative fitnesses and solving for p gives us:

W = (0.8)p²+ (2)(0.95)pq + (0.95)q² = 1

0.8p² + 1.9pq + 0.95q²  = 1

0.8p²  + 1.9p(1-p) + 0.95(1-p)^2 = 1

0.8p²  + 1.9p - 1.9p²  + 0.95 - 1.9p + 0.95p^2 = 1

0.75p²  - 1.9p + 0.95 = 0

Using the quadratic formula, we get:

p = (1.9 ± √(1.9^2 - 4(0.75)(0.95)))/(2(0.75))

p = (1.9 ± 0.97)/(1.5)

p = 0.485 or p = 1.29

Since p must be between 0 and 1, the frequency of the a2 allele at equilibrium is p = 0.485.

b. In the new environment, the relative fitnesses of the three genotypes have changed. We can use the same equations as before, but with the new values for the relative fitnesses, to find the frequency of the a2 allele in the adults after one generation of selection:

W =  p² + (2)(0.95)pq + (0.9) q² = 1

p²+ 1.9pq + 0.9 q²= 1

p² + 1.9p(1-p) + 0.9(1-p)² = 1

p² + 1.9p - 1.9p^2 + 0.9 - 1.8p + 0.9 p² = 1

p² - 1.8p + 0.9 = 0

Using the quadratic formula, we get:

p = (1.8 ± √(1.8^2 - 4(1)(0.9)))/(2(1))

p = (1.8 ± 0.84)/(2)

p = 0.472 or p = 1.328

Again, since p must be between 0 and 1, the frequency of the a2 allele in the adults after one generation of selection in the new environment is p = 0.472.

The major difference between an endospore of a bacterium and an exospore of a fungus is that B, endospores are dormant forms which are highly resistant to environmental stresses, while exospores are not.

Endospores are formed by some bacteria, such as Bacillus anthracis, as a means of survival in harsh environments. They are metabolically inactive and can withstand extreme temperatures, radiation, and chemicals. When conditions improve, the endospore can germinate and the bacterium can resume its normal life cycle.

Exospores are formed by some fungi, such as actinomycetes. They are not as resistant to environmental stresses as endospores, but they can help the fungus to disperse and colonize new areas.

Based on the given information, the most likely order of the linked genes r, s, and t would be r - s - t.

Based on the given distances between the linked genes r, s, and t, we can determine the most likely order by analyzing the map units (m.u.) between them.

The distance between t and s is 22 m.u., which suggests that t and s are farther apart from each other compared to the other gene pairs. Similarly, the distance between r and t is 14 m.u., indicating that r and t are closer together compared to t and s.

Using this information, we can deduce that the order is most likely r - t - s.

The distance between s and r is 8 m.u., which is smaller than the distance between r and t. This implies that s and r are closer together than r and t. Therefore, the most probable order of the genes is r - t - s.

It's important to note that genetic mapping is subject to variations and uncertainties, and the actual gene order can sometimes deviate due to factors like genetic recombination. However, based on the given distances, r - t - s appears to be the most likely order.

Body symmetry is defined as balanced division of body parts in an orderly manner. There are three main types of body symmetry these includes:

--> Asymmetry

--> Bilateral and

--> Radial symmetry

Asymmetrical body division involves animals that when divided, doesn't show any identical features. That is one side doesn't match the other side.. Atypical example is seen in phylum porifera, the sponges. They are simple aquatic invertebrates that lack specialised tissues.

BILATERAL SYMMETRY: This is where the body of animals can be cut along its axis in only one plane to give two identical halves, the right and the left side. The terms anterior, posterior, ventral, and dorsal are used to describe a bilateral symmetrical animal. The evolution of bilateral symmetry allow body parts to become specialised seen in most advanced animals.

RADIAL SYMMETRY: this involves animals where the body can be cut along its axis in any plane to give two identical halves. This is an ideal body symmetry for immobile organisms such as starfish and hydra.

The population after 40 years will be 400,000 animals, and the population after 65 years will be approximately 336,000 animals.

To determine the population after a certain time period, we can use the formula for exponential decay;

N(t) = N0 × \((1/2)^{(t/T)}\)

Where;

N(t) is the population at time t

N0 is the initial population

t is the time elapsed

T is the half-life of the population

Given;

N0 = 1.6 million

T = 20 years

Let's calculate the population after 40 years;

N(40) = 1.6 million × \(1/2^{(65/20)}\)

= 1.6 million × (1/2)²

= 1.6 million × (1/4)

= 400,000

Therefore, the population after 40 years will be 400,000 animals.

Now, let's calculate the population after 65 years;

N(65) = 1.6 million × \((1/2)^{(65/20)}\)

= 1.6 million × \((1/2)^{(13/4)}\)

≈ 1.6 million × 0.210
