How do earthworms get oxygen to their cells?

Biology
1 answer:
Ksju [112]3 years ago
7 0

They breathe through their skin. Air dissolves on the mucus of their skin, so they MUST stay moist to breathe.

If worms dry out, they suffocate. As fresh air is taken in through the skin, oxygen is drawn into the worm's circulatory system, and the worm's hearts pump the oxygenated blood to the head area.

A gene on a chromosome lies close to another gene controlling a different trait. This indicates that the genes are _. The first
umka2103 [35]

My guess:

I do not know the options to the blanks, but I'd say that the answer to the first one is "strongly linked". Think of a chromosome as a phylogenic chart → 2 species that are beside each other are strongly linked, if compared to 2 species 3 spots apart form each other. So, 2 genes that are close to each other are strongly linked.

I do not know the options to the blanks, but I'd say the answer to the second one is epistasis → which is the interaction between two different genes (different means they're not linked alleles).

Hope it helped,

Which protein synthesis process comes first?<br> O Translation<br> O Transcription
Mama L [17]

Answer:

Transcription

Explanation:

First comes Transcription, then comes Translation.

For example, DNA comes first, RNA comes second, and Protein comes third which makes proteins last. So, during the DNA process, Replication occurs. After that, DNA hops over to RNA using Transcription, and after that RNA hops over to Protein using Translation. So, we look left to right. Now, when I listed everything, Transcription came first and Translation came second. There is your answer.

Farmers add nitrogen to their soil, in the form of fertilizers, in order to increase crop production. Which step in the nitrogen
Sloan [31]

Ans.

Nitrogen fertilizers are commonly used by farmers to increase crop production. Ammonium is the main component of nitrogen fertilizer, as it is easily assimilated by plants and provides nitrogen to them, while nitrate gets easily lost from the soil. During nitrogen cycle, ammonium is converted into nitrate by nitrification. So, nitrification inhibitors are used with to slow down the conversion of ammonium to nitrate to provide nitrogen for longer time.

Thus, 'to increase crop production, nitrification step of nitrogen cycle is preferred by farmers to block, or slow down.'

Is there a Genetic Basis for Adapting to Life at High Altitudes? A team of scientists from the United States and China set out t
Oliga [24]

Answer:

Looking at tibetan highlanders who thrive at high altitudes- normally that would make us sick- they have adapted, 60% oxygen- could pose huge health issue (live with 10% less oxygen in blood than us)

Explanation:

Evolutionary adaptations- involve a change in the genetic makeup to help individuals survive in environment. Tibetans have adaptations to let them function at high altitudes
