The reason it is B is because a parasite usually has to feed off the host this can vary from taking nutients to Something more severe like controlling the organizim to make more of the parasite.

The main reason captive breeding programs keep detailed pedigrees of all program animals and carefully mate nonrelated individuals is to prevent inbreeding and maintain genetic diversity.

Inbreeding can result in the expression of deleterious recessive traits that are usually masked in genetically diverse populations. When a small population breeds among close relatives, there is a higher chance of these traits being expressed and becoming prevalent in the population.

Maintaining genetic diversity in captive populations is important because it ensures the survival of the population and their ability to adapt to changing environments. Careful mating of nonrelated individuals can help maintain genetic diversity by introducing new genes into the population.

Pedigree records are also important in monitoring the population's genetic health and identifying individuals with desirable traits for future breeding. By carefully managing captive populations, breeding programs can contribute to the conservation of endangered species and prevent their extinction.

The Hardy-Weinberg equilibrium is a principle elaborating that the genetic variation occuring in a population will remain constant from one generation to the next generation in the absence of disturbing factors. When mating of gamets will random in a large population with no disruptive circumstances, then the law predicts by( Hardy-Weinberg) that both genotype and allele frequencies will remain constant because they are in equilibrium state.

The Hardy-Weinberg equilibrium can be disturbed by a number of forces, including----- mutations, natural selection, nonrandom mating, genetic drift, and gene flow which all act as a disturbance factor.

Peripheral somatic nervous sense and communicate knee soreness so a person knows to stop running and rest.

A division of your peripheral nervous system that permeates almost every aspect of your body is the somatic nervous system. Your brain receives information from your senses through this system's nerves. Additionally, they allow you to move about by sending orders from your brain to your muscles.

Processing and integrating the information from the many sources so that we can formulate a reaction is done by the brain and spinal cord. Therefore, the primary role of the somatic nervous system is to link the central nervous system (CNS) with organs and striated muscle to carry out our daily activities.

Your somatic nervous system enables you to move and regulate the muscles in every part of your body. Additionally, it delivers data from your four senses—smell, hearing, taste, and touch—into your brain.

(a) Synonymous mutation: AAGTGC is the normal sequence coding for Lysine (AAG) and Cysteine (TGC). A synonymous mutation occurs when a gene changes its nucleotide sequence but the amino acid sequence remains unchanged. An example of this type of mutation using AAGTGC is AAGTGT. The translated sequence would still be Lysine (AAG) and Cysteine (TGT). This is because TGT is a codon for Cysteine, so the amino acid sequence remains unchanged.

(b) Non-synonymous missense mutation: AAGTGC is the normal sequence coding for Lysine (AAG) and Cysteine (TGC). A non-synonymous missense mutation occurs when a gene changes its nucleotide sequence and the amino acid sequence is also changed. An example of this type of mutation using AAGTGC is AAGTGA. The translated sequence would be Lysine (AAG) and Glutamic acid (TGA). This is because TGA is a codon for Glutamic acid, so the amino acid sequence is changed from Cysteine to Glutamic acid.

(c) Non-synonymous nonsense mutation: AAGTGC is the normal sequence coding for Lysine (AAG) and Cysteine (TGC). A non-synonymous nonsense mutation occurs when a gene changes its nucleotide sequence and the amino acid sequence is changed to a stop codon. An example of this type of mutation using AAGTGC is AAGTAA. The translated sequence would be Lysine (AAG) and Stop codon (TAA). This is because TAA is a codon for Stop codon, so the amino acid sequence is changed from Cysteine to Stop codon, which causes the protein to be truncated.

If the left side of the beaker has a greater concentration of urea than the right side, then A, water will leave the right side of the beaker by osmosis and join the left side of the beaker.

Osmosis occurs in this instance because there is a difference in the concentration of urea between the left and right sides of the beaker. Urea is a solute that cannot pass through the selectively permeable membrane, but water molecules can.

This is because water moves from an area of low solute concentration to an area of high solute concentration in order to equalize the solute concentration on both sides of the membrane.

Organic farming is an agricultural approach that emphasizes the use of natural and environmentally friendly practices to cultivate crops and raise livestock. It aims to minimize the use of synthetic inputs such as chemical fertilizers, pesticides, and genetically modified organisms (GMOs) while promoting sustainable farming methods.

In organic farming, soil health and fertility are prioritized through techniques like crop rotation, cover cropping, and composting. These practices enhance soil structure, increase nutrient content, and promote beneficial microorganisms, leading to long-term soil health and reduced erosion.

Organic farmers rely on biological pest management methods, such as beneficial insects, crop diversity, and cultural practices, to control pests and diseases. They avoid the use of synthetic pesticides, herbicides, and fungicides, which helps to protect biodiversity and minimize chemical residues in food and the environment.

The organic farming approach promotes ecological balance, biodiversity conservation, and sustainable production methods while striving to provide consumers with organic products that are free from synthetic chemicals and GMOs. It also encourages the adoption of regenerative practices to mitigate the environmental impacts of conventional agriculture.

Griffith demonstrated in 1928 that the ability to synthesis a capsule and consequently become virulent can be transferred from heat-inactivated “smooth” strains to surviving but avirulent “rough” strains of S. pneumoniae. Therefore, option (A) is correct.

British bacteriologist Frederick Griffith's 1928 bacteria experiment was the first to demonstrate the "transforming principle," which led to the realization that DNA serves as the carrier of genetic information.

Griffith tried injecting mice with heat-killed S bacteria as part of his investigations (that is, S bacteria that had been heated to high temperatures, causing the cells to die). Unsurprisingly, the mice were not harmed by the heat-killed S bacterium.

The first study demonstrating that bacteria are capable of transferring genetic information through a process known as transformation was conducted by Frederick Griffith.

If an egg is fertilized with an X-bearing sperm, it produces an XX zygote that is destined to become a female.

In humans and many other mammals, including most mammals with XY sex determination systems, females have two X chromosomes (XX) while males have one X and one Y chromosome (XY). The presence of two X chromosomes in the zygote leads to the development of female reproductive structures and characteristics.

During embryonic development, the XX zygote undergoes processes that guide the formation of female reproductive organs, such as the ovaries, fallopian tubes, and uterus. These structures play essential roles in the reproductive system and support the development of female secondary sexual characteristics during puberty, such as breast development and the onset of menstruation.

It's important to note that while the XX combination typically results in a female individual, there are exceptions and variations in sex determination systems across different species.

Answer:

Examination of vertebrate embryos reveals that during corresponding stages of early development,

the embryos appear to be very similar. For example, all vertebrate embryos pass through stages in

which they have gill pouches. The pouches eventually develop into the gill apparatus in fish; in laterevolving vertebrates that do not have gills, the gill pouches undergo further refinement and develop

into structures associated with the head and neck. Similarly, all early vertebrate embryos have tails,

which persist in some animals but regress during the later stages of development of humans. Thus,  

the individual development of an animal occurs through a series of stages that paint a broad picture

of the evolutionary stages (phylogeny) of the species to which it belongs.

"Ontogeny recapitulates Phylogeny", Haeckel

Explanation:

sure po ito

Examination of vertebrate embryos well-known shows that in corresponding levels of early improvement, the embryos appear very similar.

These scientists claimed that ontogeny recapitulates phylogeny (ORP). This word shows that an organism's improvement will take it thru every one of the personal levels of its evolutionary history, or its phylogeny.

Thus, the man or woman improvement of an animal happens thru a chain of levels that paint an extensive picture of the evolutionary levels (phylogeny) of the species to which it belongs.
