what provides new variation

Answers

Answer 1

Answer:

Mutation

Explanation:

The main cause of variation within a population is usually through genetic mutation.

Mutation is the alteration of the genetic sequence within an organism. It often lead to formation of new genetic patterns and codes.

Most times, environmental influences are paramount to causing genetic mutation within a population.

Other times, it might be due to competition and some other internal factors.

Mutation can be transferred from parents to offspring in most cases.

•plant to plant

Answers

Answer:

Energy transfer in ecosystem follows the 10 % law.

Explanation:

In an ecosystem model, the transfer of energy starts with the base level that is from the grass level to the grasshopper that is the primary consumer. This is a plant to animal. The energy transferred from grasshopper to snake is an example of the animal to animal. The dead and decaying animal may transfer this energy back to the plant through the soil.

If you were asked to determine if a cell is a prokaryote or eukaryote, the presence of which characteristic would be the best indicator? point​

Answers

Answer:

Nucleus

Explanation:

Prokaryotic and Eukaryotic cells are very different from each other and can be distinguished by various characteristic.

But the best indicator that determine whether a cell is a is a prokaryote or eukaryote is the presence of nucleus. Prokaryotic cell do not contain nucleus and their DNA is found in cytoplasm while Eukaryotic cell contains membrane bound nucleus and their DNA is found in nucleus.

Hence, the presence of nucleus would be the best indicator.

In a short, written response, analyze and evaluate this statement. Include the range of responses of a population to changes in the environment, such as differential reproductive success, the adaptation and development of diversity in and among species, and the change in populations.

Answers

Answer:

Those organisms survive and maintain its population who are chosen by natural selection.

Explanation:

This statement means that when the population experiences a new set of environmental conditions, two things are happened i. e. the population either adjusts through natural selection or becomes extinct. The fossil of dinosaur indicates that extinction occur due to changed in the environment. If the population made changes in itself and adapt the environment then the organism survive otherwise extinction occur.

Binary fission is a type of asexual reproduction observed in bacteria, in which one cell divides into two daughter cells.

What is binary fission?

During binary fission, there is no involvement of two parents and also there is no gamete formation occurring, so it is categorized into asexual reproduction.

There are several steps during binary fission, firstly bacteria replicates its DNA, secondly, it grows and increases the number of a cell organelle, now it segregates DNA into two parts, at the end splitting this large cell.

In DNA replication bacteria uncoils its chromosome and copy this genetic information to transfer it to subsequent generations.

Therefore, replication, cell growth, segregation, and splitting of the cell are stages of binary fission.

Which product is the result of light reactions in photosynthesis? O A. Water B. Glucose O c. Carbon dioxide OD. Oxygen ​

Answers

Answer:

D. Oxygen

Explanation:

Plants absorb carbon dioxide (CO2) and release oxygen for humans and animals to breathe in. Afterward, they'll release CO2 for plants to absorb, which forms a cycle.

Answer:

Oxygen

Explanation:

Both light dependent and light independent reactions in photosynthesis create glucose. But, only light dependent reactions convert carbon dioxide to oxygen.

Light independent: Carbon dioxide + water --> ATP and NADP(Energy/Glucose) and water

Light dependent: Carbon dioxide + water + light --> Glucose(ATP and NADP), water, and oxygen
