Answer:

Because the pathogen killed off 50% of the population that means half of the population was susceptible to the disease, meaning that genetic variation is incredibly low because 50% of the species is the same. Humans can fix this by interbreeding cheetahs with different traits, or even breed them with a different species that is compatible for reproduction.

Explanation:

Half of the population was susceptible to the disease since the pathogen killed off 50% of the population, which means that genetic variation is extremely minimal because 50% of the species are the same.

Genetic diversity refers to the total number of genetic traits that make up a species' genetic composition.

It varies greatly depending on the number of species present as well as across species, and it can be linked to a species' longevity.

A group that is genetically homogeneous and exposed to a new pathogen without the gene variant to stop the disease could go extinct.

By performing a skin graft surgery where a portion of skin from a donor cheetah is given to a recipient cheetah, which is easily accepted if it is an inbred population, evidence to support the loss of genetic diversity of the cheetah population can be gained.

By implementing captive breeding programs, encouraging females to breed with various males in order to produce offspring with various traits, protecting the natural habitat, fostering coexistence of the cheetah species with other species and humans.

Also reducing competition for the same food source, we as humans can take action to increase the genetic diversity in the cheetah population.

Thus, these are the evidence that supports how the cheetah population is likely experiencing a lack of genetic diversity.

If the base-pairing in DNA becomes non-complementary such that purine bases can pair with one another and pyrimidine bases can pair with one another, the 1:1 ratio of purine to pyrimidine bases in DNA will no longer hold.

Due to the complementary base-pairing rule, the ratio of purine to pyrimidine bases in DNAs is usually 1:1. This is because Adenine always pairs with Thymine while Guanine always pairs with Cytosine.

Once this base-pairing rule is removed and becomes purine-purine and pyrimidine-pyrimidine pairings, then it becomes unnecessary for the ratio of purine to pyrimidine bases to be 1:1.

The poem illustrating the effect of the sympathetic nervous system and the parasympathetic nervous system on Sally is:

The nervous system is the system of the body that controls how the body receives, processes and transmit information to the different part of the body.

The nervous system can be said to be the control center of the body.

The sympathetic nervous system and the parasympathetic nervous system are parts of the peripheral nervous system which have opposing effects.

The sympathetic nervous system keeps the body alert by activating the body's “fight-or-flight” response. The hearts beats faster, the respiratory rate increases, and the pupils dilate.

The parasympathetic nervous system relaxes the body after periods of stress or danger. The hearts beat normal, the respiratory rate normalizes, and the pupils constrict.

In conclusion, the sympathetic nervous system and the parasympathetic nervous system have antagonistic effects.

In a flower, this landing zone and entrance is the stigma. It plays a pivotal role in reproduction. Most stigmas are adapted to trap pollen with hairs, flaps and other surfaces to increase their efficiency. Most stigmas are covered with a waxy, sticky substance.

Deforestation and the burning of fossil fuels such as coal and oil, are the two main causes of higher concentrations of carbon dioxide in the atmosphere.

The statement "Deforestation and the burning of fossil fuels such as coal and oil have led to higher concentrations of carbon dioxide in the atmosphere" refers to the fact that human activities have significantly increased the amount of carbon dioxide in the atmosphere, leading to a rise in global temperatures and climate change.

Deforestation contributes to this problem by reducing the amount of trees that absorb carbon dioxide during photosynthesis, while the burning of fossil fuels releases stored carbon into the atmosphere. These actions have negative impacts on the environment, including increased global temperatures, rising sea levels, and more frequent extreme weather events.

Answer:

A

Explanation:

The feature that is universal among organisms, thus implying that all living things derive from a common ancestor, is The genetic code (Option A)

The genetic code is the set of rules by which DNA and RNA translate into the amino acid sequences of proteins. This code is universal, meaning that the same sequence of nucleotides in DNA or RNA will always code for the same amino acid sequence in a protein, regardless of the organism in which it is found. This universality is strong evidence for a common ancestor from which all living things have evolved.

The machinery of replication and protein synthesis, basic metabolic reactions, and the use of L optical isomers of amino acids as building blocks for proteins also support the idea of a common ancestor but are not as strong evidence as the genetic code.

Answer:

DNA synthesis is the biological process by which a deoxyribonucleic acid (DNA) molecule is created. In the cell, each of the two strands of the DNA molecule acts as a template for the synthesis of a complementary strand.

Answer:

The discovery of the double-helical nature of DNA by Watson & Crick explained how genetic information could be duplicated and passed on to succeeding generations. The strands of the double helix can separate and serve as templates for the synthesis of daughter strands. In conservative replication the two daughter strands would go to one daughter cell and the two parental strands would go to the other daughter cell. In semiconservative replication one parental and one daughter strand would go to each of the daughter cells.

Through experimentation it was determined that DNA replicates via a semiconservative mechanism. There are three possible mechanisms that can explain DNA's semiconservative replication.

(a) DNA synthesis starts at a specific place on a chromosome called an origin. In the first mechanism one daughter strand is initiated at an origin on one parental strand and the second is initiated at another origin on the opposite parental strand. Thus only one strand grows from each origin. Some viruses use this type of mechanism.

(b) In the second mechanism replication of both strands is initiated at one origin. The site at which the two strands are replicated is called the replication fork. Since the fork moves in one direction from the origin this type of replication is called unidirectional. Some types of bacteria use this type of mechanism.

(c) In the third mechanism two replication forks are initiated at the origin and as synthesis proceeds the two forks migrate away from one another. This type of replication is called bi-directional. Most organisms, including mammals, use bi-directional replication.

The following data are necessary to calculate population growth is the birth rate and the death rate.

A population grows when there are more births than deaths, and also when there is a greater flow of immigration than emigration of people. Population growth refers to the increase in the number of individuals in a specific population.

In this case, population growth is the direct relationship between people who were born and who died, the population grows when the number of individuals being born is greater than the number of deaths and when the opposite occurs, growth declines.

Blue-green algae are photosynthetic prokaryotes, while fungi are eukaryotes that obtain nutrition through absorption.

Blue-green algae and fungi are both organisms, but they belong to different domains and have distinct characteristics. Blue-green algae, also known as cyanobacteria, are classified under the domain Bacteria, while fungi belong to the domain Eukarya.

Blue-green algae are prokaryotic organisms, lacking a true nucleus and membrane-bound organelles. They obtain energy through photosynthesis and are capable of converting sunlight into chemical energy. They typically inhabit aquatic environments, such as lakes, ponds, and oceans, and some species can fix atmospheric nitrogen.

On the other hand, fungi are eukaryotic organisms with a distinct nucleus and membrane-bound organelles. They obtain nutrition by absorbing organic matter from their surroundings. Fungi play crucial roles in decomposition and nutrient cycling in ecosystems. They can be found in various habitats, including soil, plants, and even as symbiotic partners with other organisms, such as in mycorrhizal associations.

In summary, the primary differences between blue-green algae and fungi lie in their cellular structure, mode of nutrition, and classification. While blue-green algae are photosynthetic prokaryotes, fungi are eukaryotes that obtain nutrition through absorption. Understanding these distinctions helps in appreciating the diversity and ecological significance of these two groups of organisms.

The statement "Attack nonselectively on nonself cells, especially mutated and malignant cells" accurately indicates the function of natural killer (NK) cells within the immune system.

What are Natural killer cells?

Natural killer cells or NK cells are a type of lymphocyte that plays a critical role in the innate immune response.

One of their primary functions is to recognize and eliminate cells that are infected with viruses or have undergone malignant transformations, such as cancer cells.

Unlike other immune cells that require prior exposure or recognition of specific antigens, NK cells can attack a broad range of nonself cells without the need for prior sensitization.

They are particularly effective in targeting and destroying cells that display abnormal or altered surface markers, making them an essential part of the body's defense against viral infections and cancer.
