Which is not a cost for organisms that sexually reproduce?

Biology
1 answer:
Alekssandra [29.7K]3 years ago
3 0

Answer:

Identical shape and structure.

Explanation:

Those organisms that reproduce sexually have high variations and differences between the parent and its offspring. They are not identical to each other because the offspring gains half characteristics from male parent and half from the female parent making it different from its parent. Identical feature is present in the organisms that reproduce through asexually means from only one parent so the identical shape and structure is not the cost of sexual reproduction.

4vir4ik [10]

Answer:

Neurons have stable, relatively unchanging internal environments.

Explanation:

Neurons or nerve cells is the structural and functional unit of the nervous system. Neurons consists of the dendrites, axon, cell body and different cell organelles.

The neurons have mitochondria that meets the high ATP requirement and and consume more oxygen. The network of rough endoplasmic reticulum and ribosomes produce large number of proteins in neuron. The internal environment is never stable and gets changed as the nerve impulse transmission occur through the neuron. The membrane potential of the neuron gets changed and changes its internal environment.

Thus, the correct answer is option (B).

A change in direction without a change in speed is called velocity

Velocity can vary as long there is specific direction (displacement)

Speed has no direction therefore change in speed is not necessary the velocity...

Velocity is also in a specified direction

If an individual has genotype Dd, what are they?
ipn [44]

Answer:

Heterozygous dominant

Explanation:

because, as you know, heterozygous is different, and Dd has both dominant and recessive, making it heterozygous rather than homozygous.

Because the first d is dominant (capital D), then it makes the genotype dominant and heterozygous.

Bioflix activity: meiosis -- comparing mitosis and meiosis can you identify the similarities and differences between mitosis and
Natali5045456 [20]
1. Similarities:
they are both processes of cell division by which cells reproduce.
They share several steps of the process(prophase, metaphase, anaphase e telophase, cytokinesis) but meiosis has another division also with those same steps.
In both cases the cell duplicates its DNA by pulling it apart into two sets, place the sets on each end of the cell, and then divide down the middle.

Both produce new cells based on their parent cells' genes.

2. The differences:

Mitosis:

- has 1 division per cycle
- one cell produces 2 new cells
- the genetic information in the mother-cell and the daughter-cells are the same. ( the number of chromosomes is also the same)
- it occurs in somatic cells
Meiosis:
- two divisions per cycle.
- one cell when divides produces 4 new cells
- the new cells have different genetic information. mixes the  the genetic material from the parent cells
- the number of chromosomes of the daughter cells is half of the mother's.
