The primary functions of whales include feeding, reproduction, communication, and migration.

Whales are primarily filter feeders or predators, depending on the species.

Filter-feeding whales, such as baleen whales, have baleen plates in their mouths that allow them to filter out small prey, such as krill or small fish, from large volumes of water.

Predatory whales, such as toothed whales, hunt and feed on various marine organisms, including fish, squid, and marine mammals.

Reproduction is another important function for whales. Most whale species have a gestation period of several months, with females giving birth to a single calf.

The calves are nursed with milk from their mothers and rely on their care for a period of time until they become independent.

Communication is vital for whales, as they rely on vocalizations to communicate with other members of their pod.

Whales produce a variety of sounds, including songs, clicks, and whistles, which serve purposes such as mating, social interactions, and navigation.

Migration is a common behavior observed in many whale species. Whales undertake long-distance migrations, often covering thousands of kilometers, to reach feeding grounds in nutrient-rich waters or to reproduce in specific breeding areas.

These migrations are driven by seasonal changes in food availability and environmental conditions.

In summary, the primary functions of whales encompass feeding, reproduction, communication, and migration, all of which are essential for their survival and successful adaptation to their marine environments.

Explanation:

The homzyg. flowered gametes are: WW

The heterozygous plant gametes are : Ww

The 'w' allele is for purple and its recessive. The 'W' allele is for white and is dominant. The Punnett square:

      |  W   |  w   |

W  | WW | Ww |

W  | WW | Ww |

Half of them are heterozygous white and half are homzygous white. But there is no 'ww', so its 0%.

If a white-flowered plant is crossed with a plant that is heterozygous for the trait. The percentage of the offspring will have purple flowers is 75%.

A heterozygous individual is one who contains two different alleles for the traits.

The recessive allele is white p

The dominant allele is purple. P

When the crossing is done between them, 75% of the population will be purple, as shown in the diagram, and 25% of the population will be white.

Thus, the percentage of the offspring that will have purple flowers will be 75%.

The frequency of the A allele in a hypothetical population of 1,000 people, where 160 have the genotype AA, 480 have the genotype AB, and 360 have the genotype BB is 0.4 (or 40%).

To calculate the frequency of the A allele in the population, we need to use the Hardy-Weinberg equation:

\(p^2 + 2pq + q^2\) = 1

where: \(p^2\) represents the frequency of the homozygous dominant genotype (AA)

2pq represents the frequency of the heterozygous genotype (AB)

\(q^2\) represents the frequency of the homozygous recessive genotype (BB)

p represents the frequency of the dominant allele A

q represents the frequency of the recessive allele B

We can use the given information to calculate the frequencies of the three genotypes:

\(p^2\) (AA) = 160/1000 = 0.162

pq (AB) = 480/1000 = 0.482

\(q^2\) (BB) = 360/1000 = 0.36

To calculate the frequency of the A allele, we can use the equation:

p + q = 1

We know that q is equal to the square root of \(q^2\), so we can calculate q as:

q = √(0.36) = 0.6

Now we can calculate the frequency of p as:p = 1 - q = 1 - 0.6 = 0.4

Therefore, the frequency of the A allele in the population is 0.4 (or 40%).

The given statement "despite their adaptations to land, most species of plant are still aquatic" is false because despite their adaptations to land, most species of plants are not aquatic.

Most plants have adapted to life on land, and have evolved structures such as roots, stems, and leaves that allow them to absorb water and nutrients from the soil, and to exchange gases with the atmosphere. Plants have also developed structures to support their weight, resist desiccation, and reproduce in terrestrial environments. While there are some plants that have adapted to aquatic environments, such as algae and seaweed, the majority of plant species are found on land.

The main type of lipid in the blood that provides energy to the body is glycogen.

The extra energy in the food we eat is processed and stored as fat tissue in adipose tissue. The majority of the energy needed by the human body is provided by lipids and carbohydrates; in fact, 30–70% of the energy used while at rest is derived from fat. The body stores glucose as glycogen, as was previously explained.Lipids act mostly as an energy reserve while glycogen offers a rapid source of energy. Since glycogen contains a lot of water and is rather substantial, the body cannot store a lot of it for an extended period of time. Exercise burns fat as fuel, particularly after glycogen stores are exhausted. Without water, fats are compactly arranged and can store a lot more energy in a smaller area. Compared to a gramme of carbohydrate, a fat gramme has more than twice as much energy per unit of weight. In contrast to other bodily cells, which can only store a finite amount of fat, fat cells are designed specifically for storing fat and have practically limitless growth potential.

rReverse transcriptase qPCR is a powerful tool in molecular biology that allows researchers to study gene expression by converting RNA into cDNA and quantifying it using qPCR. This technique is a key component of the central dogma, which describes the flow of genetic information from DNA to RNA to protein.

Reverse transcriptase qPCR is a laboratory technique used in molecular biology to study gene expression. This technique involves the use of reverse transcriptase, which is an enzyme that converts RNA molecules into complementary DNA (cDNA) molecules. qPCR, or quantitative polymerase chain reaction, is then used to amplify and quantify the cDNA molecules. The central dogma of molecular biology states that DNA is transcribed into RNA, which is then translated into proteins. Reverse transcriptase qPCR relates to the central dogma because it allows researchers to study the first step in this process, transcription, by measuring the amount of RNA present in a sample. By converting the RNA into cDNA, researchers can then use qPCR to quantify the cDNA and determine the amount of RNA originally present.

The haplotypes inferred using the EM algorithm are: H1 = 122, H2 = 210, H3 = 212.

The EM algorithm estimates haplotypes by iteratively updating probabilities based on observed genotypes. Initially, assume equal frequencies for all haplotypes. In the E-step, compute genotype probabilities given haplotype frequencies. For G1, H1 has the highest probability.

For G2, H2 is the most likely haplotype. For G3, H3 is the most probable haplotype. In the M-step, update haplotype frequencies based on genotype probabilities.

Since we only perform one round, the updated haplotype frequencies are the final estimates. The EM algorithm suggests H1 occurs twice, H2 occurs once, and H3 also occurs once.

These haplotypes are inferred based on the observed genotypes and the assumption of uniform initial haplotype frequencies.

This means that the most likely haplotypes for the three genotypes are 122, 210, and 212, respectively.

In muscle cells, actin filaments are arranged in regular arrays and are supplemented by a collection of thicker filaments formed of a different protein called myosin. These two proteins produce the force required for muscular contraction.

Two main protein filaments make up muscles: a thick filament made of the protein myosin and a thin filament made of the protein actin. These filaments move over one another in a series of repeated actions to cause muscle contraction.

A motor protein called myosin produces the force needed to contract a muscle, much like an oar stroke does. There are two parts to it: the head and the tail. The thick filament's shaft is formed by the collective tails of about 300 myosin molecules. These molecules' myosin heads extend toward the fine filaments like the oars of a rowboat.

The thin filament in muscle cells is made up, among other things, of the spherical protein called actin. These actin molecules are wrapped around one another to form two long chains that make up thin filaments. A myosin head can attach to an actin molecule at its myosin-binding site.

The myosin moves its head groups toward the centre of the sarcomere using mechanical energy. This motion shortens and contracts the sarcomere by pulling the Actin filaments toward the center.  Muscle movement is produced by the sarcomere's contraction, which also causes the muscle fiber to contract. The 1954 Sliding Filament Model, which explains the mechanics of muscular contraction, was initially put forth.

Centrioles is found in animal cells, but not plant or algae cells.

A centriole is a cylindrical organelle in cell biology that is mostly made of the protein tubulin. Centrioles are found in the majority of eukaryotic cells, but not in conifers (Pinophyta), flowering plants (angiosperms), or most fungi, and are only detected in male gametes of charophytes, bryophytes, seedless vascular plants, cycads, and Ginkgo. A centrosome is made up of a linked pair of centrioles surrounded by a highly organized mass of dense material called the pericentriolar material (PCM).

Centrioles are normally made up of nine cylinders of short microtubule triplets. Crabs and Drosophila melanogaster embryos with nine doublets deviate from this pattern, as do Caenorhabditis elegans sperm cells and early embryos with nine singlets.

Answer: Genetics and Pressures

Explanation:

For natural selection to occur, a population must have a wide variety of individuals with different traits. For example, natural selection would not influence fish body color if all individuals in a population were exactly the same color. Variation of scale color can help a fish species have a higher chance of survival by confusing predators as to what species they are.

Reproductive strategies represent a set of behavioral, morphological, and physiological adaptations that facilitate access to potential mates, improve the chances of mating and fertilization, and enhance infant survival. Male peacocks have bright, big tail feathers, for example, to attract females. If an organism has a high appeal, this will make them more likely to be able to meet and continue the survival of the species.

Environmental pressures, such as plant death, could influence the survival of herbivorous organisms. Say a small land creature consisted off grass, and an epidemic killed all the grass in their region. They would either die off, or they would evolve to find different types of food. The former could reduce population, while the latter could increase it.
