How are adaptations passed to offspring?
Group of answer choices
Adaptations skip generations in organisms. Even if one organism "learns" an adaptation, it will be their "grandchild" organism that gets it.
Adaptations are mostly random, as they are genetic. They are written in the DNA. Changes in genes are random. If a mutation happens and the offspring of two parents has a mutation, sometimes that mutation will help it live.
The parents develop during their lifetime, so their DNA changes, and when they mate, the adaptation and then pass it on to offspring
Parents purposely CHOOSE which adaptations they give to their offspring, because they can choose which half of their genes are going to go into that organism, and predict how it will mix with it's mates genes. it is planned out to ensure species survival. This is especially true in flowering plants.
In evolutionary theory, adaptation is the biological mechanism by which organisms adjust to new environments or to changes in their current environment. The idea of natural selection is that traits that can be passed down allow organisms to adapt to the environment better than other organisms of the same species.
Therefore, the answer is :
Adaptations are mostly random, as they are genetic. They are written in the DNA. Changes in genes are random. If a mutation happens and the offspring of two parents has a mutation, sometimes that mutation will help it live.

Which statement describes how the atmosphere gains energy by convection?(1 point)
Air warmed by the ground rises.
The ground warms the air just above it.
Solar energy warms gases that make up the air.
Energy moves from the clouds to the air.
The statement that describes how the atmosphere gains energy by convection is : Air warmed by ground rises ( A )
The rising warm air from the ground into the atmosphere explains the exchange of heat energy from the ground into the atmosphere through convection and this possible due the variation in density and temperature of the ground air and the atmospheric air.
What is ConvectionConvection is the transfer of heat energy through the movement of a medium such as air or water from one region to another. convection can occur as :
Natural convection Forced convectionHence we can conclude that The statement that describes how the atmosphere gains energy by convection is Air warmed by ground rises

2. RNA polymerase is a type of enzyme. Enzymes help chemical reactions occur quickly. Click the Release enzyme button, and describe what happens.
Answer:
The nucleotides are split
Explanation:
With the release of enzyme, enzyme take part in the chemical reaction without utilizing in it.
When the enzyme release by any glands in the body, it attached to the substrate and speed up the chemical reaction without using in it. Once the chemical reaction ended, the enzyme which attached the substrate earlier detached and then attached other substrate in order to speed up the chemical reaction.
Without enzyme, chemical reaction occurs but at a very slower rate so we can conclude that with the release of enzyme, enzyme take part in the chemical reaction without utilizing in it.

1. Look at the five structures shown here. How do you think they are related to each other?
Answer:
They are all related to cells
Explanation:
;^; can you list the answers
DNA is a structure made up of two coiled polynucleotide chains with nitrogenous bases present in chromosomes. These chromosomes are present in the nucleus of the cell. These cells together form an organism.
What are Cells?Cell is define as the smallest unit which can live on its own and that makes up all living organisms and the tissues of the body. A cell has three main parts:
1. The cell membrane
2.The nucleus
3. The cytoplasm.
A nucleus is defined as the membrane-enclosed organelle within a cell that contains chromosomes. It is an array of pores, or pores, in the nuclear membrane that allow the selective passage of certain molecules, such as proteins and nucleic acids, into and out of the nucleus.
Chromosomes are define as the threadlike structures made of protein and a single molecule of DNA which serve to carry the genomic information from cell to cell. These DNA (Deoxyribonucleic acid) is a polymer which is composed of two polynucleotide chains that coil around each other to form a double helix consisting of nitrogenous bases.
Thus, DNA is a structure made up of two coiled polynucleotide chains with nitrogenous bases present in chromosomes. These chromosomes are present in the nucleus of the cell. These cells together form an organism.

2. A food web explains why there are more _____. It is because more energy is available to _____. A. Decomposers than consumers / consumers b. Producers than decomposers / consumers c. Consumers than producers / producers d. Producers than consumers / producers
Answer:
D
Explanation:
A food web explains why there are more producers than consumers. It is because more energy is available to producers.
The food web is a structural representation of the feeding relationship that exists among the living organisms in a particular environment.
A typical food web groups living organisms as producers, consumers, or decomposers. Producers are those that fix sunlight energy into chemical energy, a process known as photosynthesis while consumers are those that either feed on producers or other living organisms in the environment. The decomposers return both producers and consumers back to the earth and help nutrients circulate in the environment.
In a typical food web, producers are usually more than consumers because more energy is usually available at this level. Less and less energy becomes available as we move up the ladder in each food chain that makes up the food web.

A)an input of energy as both phosphate groups detach
B)a release of energy as one phosphate group detached
C) a release of energy as a third phosphate group is attached
D) an input of energy to attach a third phosphate group
Answer:
D
Explanation:
The option that describes the conversion of ADP to ATP is D) an input of energy to attach a third phosphate group.
What is ADP?ADP (adenosine diphosphate) is a molecule that is made up of adenosine and two phosphate groups. ATP (adenosine triphosphate) is a molecule that is made up of adenosine and three phosphate groups. The conversion of ADP to ATP is an energy-intensive process that requires an input of energy.
The third phosphate group is attached to ADP by a process called phosphorylation. Phosphorylation is an energy-requiring reaction that uses ATP as a source of energy.
