Respiration in echinoderms​

Biology
1 answer:
choli [55]3 years ago
8 0
In general, echinoderms typically respire by simple diffusion, using gills or specialized projections, like tube feet or pockets, to circulate water and oxygen through their bodies. Many echinoderms also use a simple hemal system, a series of pockets and tubes that serves almost like a net of veins and arteries.

According to linnaean taxonomy, what is the most specific category and level shared by humans, gorillas, and howler monkeys (fro
Mkey [24]

The most specific category and level shared by humans, gorillas, and howler monkeys (from the new world) are Suborder Anthropoidea.

<h3>What is suborder Anthropoidea?</h3>

Anthropoidea is a suborder of primates that includes humans, gorillas, and monkeys. Anthropoids are larger than prosimian primates and have flatter, more human-like faces. They also have larger brains.

Unquestionably apes, dryopithecines lived in the following Miocene. According to the conventional palaeontological theory, these Miocene apes gave rise to three new lineages in turn, one of which led to gibbons, another to big apes, and the third to humans.

However, it has long been held that the ancestors of both gibbons and orang-utans diverged from the ancestral line of the advanced Primates at an early date and that this line only later split into two groups, one of which included humans and the other of which included the gorilla and the chimpanzee; recent palaeontological evidence now tends to support this second view.

Which substance plays a major role in most of the chemical reactions that occur in living cell
KonstantinChe [14]

Water

Water is the substance that plays a major role in most of the chemical reactions that occur in living cell.

Water is a clear, tasteless, and odourless substance that is found in high amounts in living organisms, and is required by all forms of life. Water plays a major role in most of the chemical reactions that occur in living cells. Water is present both within and outside cells, and almost all chemical reactions take place in water solution. Water also acts as metabolite in many chemical reactions. It is either a reactant or a product of reaction. Water is involved in chemical processes such as digestion, photosynthesis, and aerobic respiration.

(This is about DNA)
n200080 [17]

Answer:

B. 20%

Explanation:

The complementary base-pairing rule states that Adenine always pairs with Thymine (A with T), and Cytosine with Guanine (C with G).

Because of this, the amount of Adenine present must be the same as the amount of Thymine present, and the same for Cytosine and Guanine.

This means that if there is 30% Adenine, there is also 30% Thymine as each A base is paired to a T base. This adds to 60%, so Cytosine amounts and Guanine amounts must add to 40% to make 100%.

Since they are equal in amount, there must be 20% of each.

Therefore the answer is B. 20%

There is 30% Adenine, 30% Thymine, 20% Guanine and 20% Cytosine.

Hope this helped!

What shows that the results of an experiment are reliable
Alecsey [184]

Answer:

When a scientist repeats an experiment with a different group of people or a different batch of the same chemicals and gets very similar results then those results are said to be reliable.

Explanation:

Reliability is measured by a percentage – if you get exactly the same results every time then they are 100% reliable. hope this helps you :)
