where do adaptations come from?

Answers

Adaptations are the result of evolution. Evolution is a change in a species over long periods of time. Adaptations usually occur because a gene mutates or changes by accident! Some mutations can help an animal or plant survive better than others in the species without the mutation.

Adaptations come from natural selection acting on heritable genetic variation within a population.

What is an adaptation?

Adaptations come from a combination of genetic variation and natural selection. Genetic variation refers to the differences that exist between individuals within a species, which can be inherited from their parents or arise from mutations.

Natural selection acts on these variations, favoring those traits that provide an advantage in a particular environment. Over time, this process can lead to the development of new adaptations that better suit an organism's needs and increase its chances of survival and reproduction.

Adaptations can also be shaped by other factors, such as the influence of cultural practices or human intervention.

B. Modern farming equipment has made more food available to
many more people than in the past.
C. Farmers use larger equipment to plant and harvest more grain in
less time.
D. Machines have replaced much of the manual labor once needed to
run a farm.

Answers

Answer:

The answer is option D "Machines have replaced much of the manual labor once needed to run a farm."

Explanation:

* Progress in Engineering: This simply means how technological machines like heavy tractors which are now used and are helpful in farming are  evolving, meaning they are being used in a larger quantity now.

* Natural Environment: This is the normal way of life or doing things which individuals find themselves practicing in a particular society and at a particular point in time.

* As a result of the machines being developed as an Engineering progress which serves the work of people on the farms, there tends to be less manual labor that would be initially required to run a farm. The machines are now serving the work of human beings (laborers) now.

On an island, finches that fed on large, hard seeds had large beaks. Finches with small beaks fed on small, soft seeds. A drought changed the vegetation on the island.

During mitosis, what happens to the parent cell?

Answers

Answer: it produces 2 daughter cells

Explanation:

Just took the test

During the mitosis, the parent cell changes in size as more protein and RNA synthesis takes place, and then finally, the parent cell is divided into two equal daughter cells.

What changes occur in parent cells during the cell cycle?

The parent cell enters the cell cycle as the cell growth is necessitated, and in the first phase, which is the G1 phase, the cell growth takes place due to the increased transcription and translation rates that are needed for the next phases of the cell cycle, and then the DNA replication takes place, and at last the parent cell equally divides to make two daughter cells.

Hence, during the mitosis, the parent cell changes in size as more protein and RNA synthesis takes place, and then finally, the parent cell is divided into two equal daughter cells.

A) cell growth
B) transferring NADPH into NADP
C) converting ATP into ADP
D) capturing energy from sunlight

Answers

Explanation:

D) capturing energy from sunlight

Pigments found in plants are necessary for capturing energy from sunlight, to do photosynthesis, hence option D is correct.

What is the role of pigments in photosynthesis?

The principal pigment in photosynthesis, chlorophyll, reflects green light and significantly absorbs red and blue light. Chloroplasts, which house the chlorophyll in plants, are where photosynthesis occurs.

They use light as their energy source and sense light to regulate their growth and quick reactions to their surroundings. In order to promote rewards for animals that pollinate flowers and spread seeds, plants generate pigments.

Therefore, chlorophyll, carotenoids, and anthocyanin are examples of pigments whose primary role in photosynthesis is to absorb light and use it to excite electrons that then trigger a series of events that allow photosynthesis to begin.

how does energy flow in this terrarium in terms of photosynthesis and cellular respiration

Answers

Explanation:

through photosynthesis setting organs convert solar energy to chemical energy which is then used to build carbohydrate molecules .the energy used to hold this molecule together is released when an organism breaks down food .cell then use this energy to perform work known as cellular respiration

For photosynthesis, plants require carbon dioxide and sunshine. Through chemical reactions powered by chemical energy, they generate glucose and oxygen. Plants naturally create oxygen and absorb carbon dioxide.

What is photosynthesis?

Both humans and animals depend on cellular respiration. They breathe in oxygen and food, which they then chemically digest and expel carbon dioxide from.

For life to continue on Earth, this cycle is necessary. Setting organs transform solar energy into chemical energy through photosynthesis, which is then utilized to create carbohydrate molecules.

When a creature breaks down food, the energy that was utilized to hold this molecule together is released. Cellular respiration is the process through which a cell uses this energy to carry out work.

Therefore, through chemical reactions powered by chemical energy, they generate glucose and oxygen.
