Answers

Answer:

Hi, I can help you!

Explanation:

There are more than 3,000 species of snakes on the planet and they’re found everywhere except in Antarctica, Iceland, Ireland, Greenland, and New Zealand. About 600 species are venomous, and only about 200—seven percent—are able to kill or significantly wound a human. Snake vision varies greatly between species. Some have keen eyesight and others are only able to distinguish light from dark, but the important trend is that a snake's visual perception is adequate enough to track movements. A young snake that is still growing may shed its skin up to four times a year, but an older snake may shed only once or twice a year.Snake venoms are complex mixtures of proteins, and are stored in venom glands at the back of the head.[

Compared to a rounded particle with low density, a HIGH density,
rounded particle of the same size will sink through water

•more slowly
•at the same rate
•more rapidly

Answers

Answer:

more rapidly

Explanation:

Density of a substance refers to the mass of that substance in relation to one unit of its volume. The density of a substance is the basis of whether such substance will float or sink in a liquid. This means that if the density of an object is higher than that of a liquid medium e.g water, the object will SINK while if the density of the object is lower in relation to the liquid medium, the object will FLOAT.

According to this question involving a rounded particle. If the rounded particle is of low density than water, it will float. However, if the rounded particle of the same size is of HIGH density than water, it will SINK MORE RAPIDLY.

What is mRNA?

The messenger RNA (mRNA) is a template created during transcription, which is used to generate a protein.

A specific fragment of DNA is used to create this template (mRNA) by transcription.

In RNA, Thymine nucleotide bases are replaced by Uracil nucleotide bases.

In conclusion, the messenger RNA (mRNA) code for this segment of the hemoglobin DNA gene is ACG-CCU-GAG-GAG (Option B is correct).
