The answer is c. Deciduous trees lose their leaves to prevent nutrient and water loss.

Losing leaves is a trees' strategy to survive cold winters. It is known that trees primarily lose water through leaves. In the winter, there is no enough water to replace that lost water. If the trees were not to throw away their leaves, they will soon dry out. Also, before falling the leaves begin, reabsorb all nutrients from the leaves and store it for the cold winter. Thus, losing leaves is important to prevent both nutrient and water loss during the winter.

Explain three differences between apomictic and automictic parthenogenesis.

Apomictic refers to plants and it means the offspring is genetically identical to the parent. Automictic means that gametes fuse after meiosis - which means offspring are genetically not identical to parents.

Why do we want to turn genes off or on?
Dmitrij [34]

The process of turning off and on of genes is known as gene regulation.

Explanation:

When the gene is turned on, it instructs the cells to construct a particular protein. The proteins are the molecules that build your body with collagen, tendons, and bones or keratin in your hair.

The gene regulatory proteins allow the individual genes of an organism to be turned on or off . in different cell types there are different selections of gene regulatory proteins. The patterns of the gene expression gives each cell its unique characteristics.

Each cell produces or turns on only a fraction of its genes. the remaining genes are repressed or turned off. this process is known as gene regulation. The signals from the environment or from other cells activate proteins called transcription factors.

PLS help!!!!!! brainliest!!!! which activity produces an action potential in nerve cells?
olga55 [171]

Answer:

C. release of neurotransmitters

Explanation:

The action potential is an explosion of electrical activity that is created by a depolarizing current. This means that some event (a stimulus) causes the resting potential to move toward 0 mV. When the depolarization reaches about -55 mV a neuron will fire an action potential.
