Biology
1 answer:
yKpoI14uk [10]3 years ago
7 0

Answer:

It is necessary to separate oxygenated and deoxygenated blood separate in mammals and birds to maintain their body temperature. Also, if they both are mixed, the blood will get impure and it would be difficult for the heart to supply impure blood. We also can't live with impure blood so we most probably will die.

Atmospheric nitrogen has to be combined with other elements
Alecsey [184]

Nitrogen in gaseous amount is 78% which is present in atmosphere. It has to be combined with other elements, or fixed, in order to be used by plants. Lightning is one way fixation of atmospheric nitrogen because when lightning occurs, the extreme heat melts the nitrogen molecules bond, allowing nitrogen to combine with oxygen and form nitrogen oxides.

<h3>What is atmosphere?</h3>

An atmosphere is referred to a layers of gases which envelope a planet, and is held in place by the gravity of the planetary body.

By a series of microbial transformations nitrogen is made available to plants, which in turn ultimately sustain all animal life.

Which statement is true about a species living in a homogenous environment compared to a species living in a heterogeneous envir
Dovator [93]

Answer:

A species that lives in a heterogeneous environment is more likely to exhibit phenotypic plasticity.

Explanation:

Phenotypic plasticity might be understood as the ability of a genotype to produce different phenotypes in response to varying environmental conditions.

Phenotypic plasticity needs epigenetic mechanisms to occur, which involve the genotype and the environment interaction to produce adapted phenotypic changes.

Epigenetic mechanisms produce changes in the expression of the genes, with no need to alter the DNI nucleotides sequences.

A heterogeneous environment imposes variability on genotypes that interact with it, producing different phenotypes. These phenotypes will vary according to environmental conditions.
