Which kind of exercise targets muscle cells instead of the cardiovascular system to meet the rapid demand for energy?
Fynjy0 [20]

The correct answer is anaerobic exercises. Anaerobic exercises is an intensely done activity, wherein the body’s call for oxygen goes beyond the oxygen source accessible within the body. Anaerobic exercises feeds on the energy sources that are stored in the muscles of the body, which is why it is the exercise that targets muscle cells for maximum demand of energy.

evidence of the endosymbiosis theory was found in the : nucleus and cytoplasms, mitochondria and endoplasmic reticulum, mitochon
alina1380 [7]

Answer:

Mitochondria and chloroplasts

Explanation:

These two organelles support the theory in that both have 70S ribosomes, the presence of a circular DNA within, and similar size. They can undergo division within the eukaryotic cyptoplasm. Both of these organelles are surrounded by a double membrane, which in the case of chloroplast is known to originate from ancient bacteria that lost its peptidoglycan component. Mitochondria and chloroplast both evolved from ancient free living bacteria that entered into larger cells, which in the case of mitochondria is known to be archaea and in the case of chloroplast is a eukaryotic cell. With this, these cells became dependent on it in a manner that it could not exist without it.

Which is an example of codominance? (1 point)
Dafna11 [192]

Answer:

roan coat color in horses

Explanation:

Codominance is one of the Non-mendelian inheritance patterns in genetics i.e. does not follow Mendel's principles of inheritance. Codominance is a phenomenon whereby an allele is neither dominant nor recessive to another in a gene i.e. one allele is not phenotypically expressed over the other. Hence, both alleles are simultaneously expressed in their heterozygous state.

An example of codominance is the roan coat color in horses where the colored (B) and white (W) alleles are both dominant in the coat color gene, hence, the horse expresses both black and white coat phenotypes known as ROAN (BW). The black and white alleles are said to be CODOMINANT.
