Answer:
a- after a mass extinction , because the survivors give rise to species that fill new inches
Explanation:
Adaptive radiation is a phenomenon that refers to the process in which there occurs an enhanced diversity of organisms and old specie give rise to the evolution of a diverse array of new species.
The process of adaptive radiation can occur under special circumstances for example, when there occurs a change in environment in such a way that there are more environmental resources to sustain new organisms.
There is a famous example of Adaptive radiation that is finch speciation on the Galapagos that was well studied and researched by Darwin.
Here are the conditions under which adaptive radiation can occur:
A volcanic explosion has occured that opened up new habitats for the speciation. For example: The volcanic eruption in Hawaii that created an Island in middle of ocean.Any event in which specie extinction occurred and and that open up new niches for the habitat formation and speciation.If the newly created habitat is far off and isolated from an environmental which is populated. There are chances that new specie will colonize in that newly created habitat.New habitat has enormous amount of resources to sustain the survival of diverse array of species.In view of above facts, option A is best option.

critique the phrase airspeed velocity of a swallow
Critique the phrase airspeed velocity of a swallow as Its redundant. The velocity of a flying object already includes its airspeed.
When we think of African or European swallow?It's obvious, you'll be thinking of African or European swallow; we might consider the West African swallow, or the South African Cave swallow, however, choosing one between these two would be completely arbitrary- and neither is it sufficiently studied to provide the absolute data we need.
Not withstanding, there is an accepted way to estimate the airspeed of a bird using Strouhal ratio's equation. This states that "the frequency of wingbeats multiplied by their amplitude and divided by the airspeed of the bird provides a semi-constant value." This is known as the Strouhal number and averages between 0.2 and 0.4 for most birds, with a higher number denoting a less efficient flight pattern.
Flight is (for those poor people who we're not opportune to watch it) clearly very efficient, seeming almost effortless. So we’ll go for the lower end of Strouhal numbers in our working, giving us (drumroll please), an airspeed velocity of 11–16 metres per second. That’s 40–60 kilometers per hour.
Therefore, Critique the phrase airspeed velocity of a swallow as Its redundant. The velocity of a flying object already includes its airspeed.

what is the genotype for a recessive trait found in the female chromosome
Genotype for a recessive trait found on the female chromosome is b.
A female with two copies of a recessive allele on her X chromosomes is homozygous for an X-linked recessive trait. She will pass on this trait to her male offspring. Female carriers with one recessive and one dominant allele can pass on the carrier status or the disease to their children.
The genotype for a recessive trait carried on the female X chromosome is represented by two alleles, one on each X chromosome. When it comes to X-linked recessive traits, females need to inherit two copies of the recessive allele to express the trait. If they inherit only one recessive allele and one dominant allele, they are considered carriers and do not usually show the trait.
In humans, ailments such as certain forms of color blindness, hemophilia, and muscular dystrophy are examples of X-linked recessive conditions. A female who is homozygous for a recessive X-linked trait (meaning she has two copies of the recessive allele, one on each X chromosome) will pass this trait on to all of her male offspring. This is because males have one X and one Y chromosome, and they will inherit the Y chromosome from their father and the X chromosome from their mother. If a woman is heterozygous for the trait (having one recessive and one dominant allele), she may not express the disease but can still pass on the carrier status to her daughters or the disease to her sons.

Which is not a drawback of using fossil fuels ?
A. They release radioactive waste
B. They cause air pollution
C. They release greenhouse gases
D. They are non renewable
Answer:
A) They release radioactive waste.
Explanation:
Fossil fuels are non renewable resources do not release radioactive wastes / materials, but they do release greenhouse gases, causing air pollution.
Final answer:
The statement not associated with the drawback of using fossil fuels is that they release radioactive waste. Fossil fuels cause air pollution and release greenhouse gases and are non-renewable, but do not create radioactive waste. Thus, option A is correct.
Explanation:
The question asks to identify which statement is not a drawback of using fossil fuels. The correct answer is A. They release radioactive waste. This is a drawback associated with nuclear power, not fossil fuels. However, fossil fuels are known to cause significant air pollution, emit greenhouse gases, and are non-renewable resources.
Fossil fuels, such as coal, oil, and natural gas, take millions of years to form and hence are classified as non-renewable. The combustion of these fuels releases large quantities of carbon dioxide (CO2), which is a greenhouse gas that contributes to global warming. Additionally, the burning of fossil fuels results in the release of pollutants into the air, contributing to air pollution.

The frog population in this ecosystem is rapidly decreasing due to pesticide use. Bird watchers in the area express their concerns about the impact the loss of frogs will have on birds. Officials hire a scientist to study the system and give an opinion.
Which statement would be the most likely response from the scientist?
A.Loss of frogs is likely to increase grasshopper populations so all bird populations are also likely to increase.
B.Loss of frogs is likely to have little effect on bird populations because birds can easily switch food sources.
C.Loss of frogs is likely to have positive effects on some bird species and negative effects on others.
D.Loss of frogs is likely to negatively affect all bird species in the food web because a prey species would be lost
I would say the answer is A or B
The scientist would likely suggest that the decrease in frog population may have both positive and negative impacts on various bird populations, based on their individual adaptability and alternate food sources.
Explanation:The most likely response from the scientist studying the ecosystem and decreasing population of frogs would be option C: 'Loss of frogs is likely to have positive effects on some bird species and negative effects on others.' This is because every species in an ecosystem is interconnected. Frogs are a food source for certain bird species, and their loss could lead to declines in those bird populations. However, some other bird species might benefit if they can easily switch to other food sources, such as insects or small mammals, that might become more abundant in the absence of frogs.

This is any cell in a living organism that is not part of reproduction.
Example: skin cells, muscle tissue
The answer to your question are the Somatic cells. They are all of the cells that are not related to reproduction. Hope this helped!
Answer: Somatic cell
Explanation:
A somatic cell is any cell forming the body of an organism that is not a gamete, germ cells or undifferentiated stem cell. For example, skin cell, muscle cell, blood cell and others. Thereby, they are all cells that make up an organism and are not used to form a new organism during reproduction. New somatic cells are created through mitosis, when a cell divides to form two identical diploid cells. The major purpose of this type of cell division is for growth and to replace cells.
Germ cell give rise to the gametes, which are reproductive cells (egg or sperm). They are haploid cells because they carry only one copy of each chromosome. They create new gamete cells through meiosis. And undifferentiated stem cells can divide to produce other cells that continue as stem cells or cells that are destined to differentiate.

A genetic mutation involving a single base causes an error that affects the sequence of the next 500 amino acids in a protein. Which type of mutation could have produced this type of error in the protein?
A)Silent
B)Nonsensse
C)frame-shift
Answer:
C)frame-shift
Explanation:
Since the protein-encoding DNA is divided into codons of three bases each, insertions and deletions can alter a gene to the point that its message loses its meaning. These changes are called the reading frame offset.
For example, consider the phrase: "The fat cat sat". Each letter represents a codon. If we delete the first letter and try to analyze the sentence in the same way, it doesn't make sense. In frame-shift, a similar error occurs at the molecular level, causing the codons to be analyzed incorrectly. This usually produces useless proteins.

Which of the following will pass through a cell membrane most easily? A) small polar molecules B) small nonpolar molecules C) large polar molecules D) large nonpolar molecules E) large neutral molecules
B) small non-polar molecules. Small molecules can pass through the cell membrane through diffusion (does not require energy). The molecule being non-polar is an advantage because the tails of the phospholipid bilayer is hydrophobic (nonpolar), so it does not repel nonpolar molecules.
Small nonpolar molecules, due to their compatibility with the nonpolar interior of the cell membrane, will pass through a cell membrane most easily.
Explanation:As per the properties of the cell membrane, small nonpolar molecules will pass through a cell membrane most easily. This is because the cell membrane is a lipid bilayer, in which the main components are phospholipids. These phospholipids are made up of a polar 'head' and two nonpolar 'tails'. Hence, the nonpolar (hydrophobic) interior of the cell membrane allows nonpolar molecules like oxygen and carbon dioxide to easily cross the membrane without requiring any additional energy, hence making choice B) the answer to your question.

The Hardy-Weinberg principle is written as an equation: p2 + pq2 + q2 = 1. What does the q represent?
the size of the population
the size of the gene pool
frequency of the dominant allele
frequency of the recessive allele
Answer:
The correct answer option is: frequency of the recessive allele.
Explanation:
When there are no mutations, no selective forces, no gene flow, no non-random mating and large population size, the population is said to be in Hardy- Weinberg equilibrium.
When Hardy-Weinberg equilibrium is met, it is written in the form of an equation which is as follows:
[tex]p^2+2pq+q^2=1[/tex]
where [tex]p^2[/tex] represents the frequency of the homozygous dominant allele, [tex]2pq[/tex] is the frequency of the heterozygous allele while q or[tex]q^2[/tex] represents the frequency of the homozygous recessive allele.

What is a point source pollution?
Answer:
Point source pollution and nonpoint source pollution are both potentially harmful to the environment. The main difference between point source pollution and nonpoint source pollution is that point source pollution is easier to track to its source. The source of pollution is easily identifiable in point source pollution, but not in nonpoint source pollution. For this reason, point source pollution is easier to regulate and therefore easier to control. This makes nonpoint source pollution potentially more harmful to the environment.

generally describe what forces ultimately shaped the earth into its modern form
The force of gravity is a major force that created the earth. As rocks and ice clumped together as they spun around the newly formed star (sun), the force of gravitational pull increased and attracted more debris (rocks and ice). The clumps of rocks, debris, and ice, therefore, grew into a planet.
Another is electromagnetic force. The spinning currents in the outer core of the earth create a dynamo effect that forms a magnetic field around the earth. This shields the earth from the solar storms of the sun hence protects life and the atmosphere.
Weak nuclear force is responsible for maintaining the heat of the earth’s interior which is critical for maintaining the dynamo effect of the outer core so the earth is protected by its magnetic field.
