Answers

Answer 1

Answer:

Na (sodium) and HCl (hydrochloric acid)

Explanation:

The products are the salt and hydrogen gas

Whenever you see the word react it means those are the reactants (usually whatever compound comes before and after the word). Because they are reacting with each other.

Whenever they say "is produced" those are the products

Which of the following requirements for the Hardy-Weinberg equilibrium is not being met?

Answers

Answer:

A

Explanation:

All mating must be totally random

Hardy-Weinberg equilibrium is a mathematical model that describes the genetic equilibrium of a population in terms of allele frequencies. It states that allele frequencies in a population remain constant over time in the absence of any evolutionary forces.

What are the requirements of the law ?

In order for this balance to be maintained, five basic requirements must be met: large population size, random mating, no mutations, no migration, and no natural selection. In this case, the starfish population does not satisfy the fifth requirement for no natural selection.

Natural selection occurs as individuals with the purple allele die off, resulting in the red allele becoming more common over time. This type of directional selection causes allele frequencies to deviate from Hardy-Weinberg equilibrium.

Therefore, no natural selection requirement is met in this starfish population. This causes allele frequencies to change over time, leading to a deviation from Hardy-Weinberg equilibrium.

If something is 12 grams and has a volume of 1.6 cubic centimeters, how many grams per cubic centimeter.

Answers

Answer: 7.5  grams per cubic centimeter.

Explanation:

We area given that , Mass of something is 12 grams

Volume of that thing is 1.6 cubic centimeters

To find gram per cubic centimeters, we will divide Mass by Volume ( which computes Density)

Number of gram per cubic centimeters = [tex]\dfrac{12}{1.6}[/tex]

C.
2

D.
4

Answers

Answer:

C: 2

Explanation:

Glycolysis yields two ATP molecules, two NADH molecules, and two pyruvate molecules: Glycolysis, or the aerobic catabolic breakdown of glucose, generates energy in the form of ATP, NADH, and pyruvate, which then feeds back into the citric acid cycle to generate additional energy.

In the process of glycolysis, glucose eventually decomposes into pyruvate and energy, yielding a total of 2 ATP. Therefore, option (C) is correct.

What is glycolysis?

The metabolic mechanism known as glycolysis is responsible for the transformation of glucose into pyruvate. This process results in the liberation of free energy, which is then put to use in the production of high-energy molecules such as adenosine triphosphate and reduced nicotinamide adenine dinucleotide. Enzymes are responsible for catalyzing each of the ten processes that make up glycolysis.

The breakdown of glucose into pyruvate and energy occurs at the end of glycolysis. This process results in the production of a total of two ATP molecules.

Therefore, option (C) is correct.

Answers

Answer:

I think the answer to this question is O population, community, ecosystem.

Population, community, and ecosystem show the levels of organizational hierarchy from least complex to most complex. Therefore, the correct statement is option A.

What is the community consisting of?

A community is made up of all the populations of different species that live in the same area and interact with one another. A population is a group of people from the same species who live there.

A biological system remembers every one of the living organic entities for a local area, as well as the actual climate in which they live and connect. In this order, the population is the most un-complex level, as it alludes to a gathering of people of similar species.

Community is more complicated because it involves interactions between multiple species populations. Because it encompasses all living and nonliving components of an area as well as their interactions, the ecosystem level is the most complex.

Therefore, population, community, and ecosystem show the levels of organizational hierarchy from least complex to most complex.

What is the dominant phenotype of the offspring in the cross shown?


A.Ff
B.FF
C.blue

Answers

Answer:

C. blue  

Explanation:

In genetics, homo-zygous individuals are those individuals that have the same allele form (i.e., the same allele) for a given gene/locus, whereas heterozygous individuals have different alleles for that gene/locus. Complete dominance is a form of dominance that occurs when the allele that is dominant for a given gene/locus completely masks the effects of the recessive allele in a heterozygous individual. In this case, individuals that are heterozygous (genotype Ff) exhibit a dominant flower-blue phenotype because the dominant 'F' allele completely masks the effect of the recessive 'f'  allele; therefore producing a phenotypic ratio of 3:1 in the offspring of a mating between two heterozygous individuals for this single trait.

A population of tree frogs lives in an area that has many types of plants and trees. The skin of most of the frogs is gray, which blends in better with the bark of trees than with the leaves of plants. Some of the frogs have skin that is greener in color, which blends in better with grasses and leaves. Snakes and birds are predators of the frog. Humans have come to the area and are beginning to cut down the trees. Describe the probability of survival for the three frogs of each genetic variation of skin colour if most of the trees are cut down. Use evidence in the paragraph to support your answer.

Answers

Answer:

with the normal natural predators their chances of survival are high but when humans step in entire forests can be wiped out which will endanger every species of frog

If most trees are cut down, grey individuals will not survive because they will be more exposed to predation. Green frogs will show a greater survival rate. Directional selection is favoring the green phenotype and its genotype.

What is directional selection?

Directional selection is one of the different types of natural selection.

It increases the proportion of individuals with an extreme phenotypic trait.

It causes a decrease in the number of individuals expressing intermediate phenotype, and the other extreme phenotype.

This selection presents more frequently in those cases in which interactions between living organisms and the environment modify in the same direction.

In the exposed example, there is a natural environmental pressure: predation.  Frogs need to camouflage to avoid being seen by birds and snakes.

Most frogs are grey. They camouflage with the bark of treesSome other frogs are green. They camouflage with the grass and leaves.

The curve in a graph frequency vs phenotype shows a higher frequency of gray individuals.

When humans cut down the trees, they are applying another pressure to the population.

Since humans remove trees, grey frogs remain without a substrate in which to camouflage. They are now exposed to predation.

Birds and snakes can detect the gray frogs better and prey on them.

The grey phenotype and its genotype are affecting the animals' fitness. Grey frogs do not get to survive. So natural selection does not favor it.  

Natural selection tends to benefit the green phenotype, which is now the one that increases the frogs' fitness. Green animals are not seen by predators, so they get to survive.  

The curve in a graph frequency vs phenotype now shows a higher frequency of green individuals and a sharp decrease of grey frogs.

If more trees are cut down, grey individuals will not survive. However, green frogs will show a greater survival rate.

Directional selection is favoring the green phenotype and its genotype.

Nature constantly adjusts the atmospheric carbon level. An increase in the level causes the atmosphere to hold more heat, which causes more water to evaporate from the oceans, which causes increased rain. Rain washes some carbon from the air into the oceans, where it eventually becomes part of the seabed. A decrease in atmospheric carbon causes the atmosphere to hold less heat, which causes decreased evaporation from the oceans, which causes less rain, and thus less carbon is washed into the oceans. Yet some environmentalists worry that burning fossil fuels may raise atmospheric carbon to a dangerous level. It is true that a sustained increase would threaten human life. But the environmentalists should relax—nature will continually adjust the carbon level.

Which one of the following, if true, would most weaken the argument in the passage?

(A) Plant life cannot survive without atmospheric carbon.
(B) It is not clear that breathing excess carbon in the atmosphere will have a negative effect on human life.
(C) Carbon is part of the chemical "blanket" that keeps the Earth warm enough to sustain human life.
(D) Breathing by animals releases almost 30 times as much carbon as does the burning of fossil fuels.
(E) The natural adjustment process, which occurs over millions of years, allows wide fluctuations in the carbon level in the short term.

Answers

Answer: E) The natural adjustment process, which occurs over millions of years, allows wide fluctuations in the carbon level in the short term.

Explanation:

If the natural adjustment process takes millions of years then it nature will not be able to adjust the levels of carbon in the atmosphere fast enough. This means that in the short term, carbon levels will fluctuate widely if more fossil fuels are burnt.

It is therefore necessary that humans reduce how much fossil fuels that burn to ensure that in the short term, situations on earth are manageable while the adjustment process goes on for millions of years.
