PLEASE HELP ASAP<br><br> how does the ribosome read the mRNA?
ValentinkaMS [17]

Answer:

A ribosome is made up of two basic pieces: a large and a small subunit. During translation, the two subunits come together around a mRNA molecule, forming a complete ribosome. The ribosome moves forward on the mRNA, codon by codon, as it is read and translated into a polypeptide (protein chain).

In sheep, white wool is dominant over spotted wool. If 10 purebred white wool sheep (TT) are crossed
Anon25 [30]

Answer:

0

Explanation:

This question involves a single gene coding for wool color in sheeps. The allele for white wool (TT) is dominant over the allele for spotted wool (tt). This means that a sheep with an heterozygous genotype (Tt) will be white-wooled.

In this cross, 10 purebred white wool sheep (TT) are crossed with 10 spotted wool sheep (tt). This will give rise to all offsprings with heterozygous genotype: Tt (see attached image for punnet square). Since, white wool (T) is dominant, all the offsprings will have a white wool and none i.e. 0 will have a spotted wool.

1. Do some research and try to identify one to three types of microbes cultured on your plates. Using any resources available to
yarga [219]

Answer:

I have identified <em>Escherichia coli </em>and<em> Bacillus sp.</em>

Explanation:

I obtained my sample from soil, in a park near my house. The common bacteria on soil are gram positive and gram negative.

I found rods, and some are gram positive and long. They others are gram negative and very small and short.

The color of the gram positive is a dark blue, almost purple, and they are big and abundant, they are almost in lines, so I think they are a species of <em>Bacillus.</em>

The gram negative bacteria are extremely small and they look hot pink. They are very probably enterobacteria, and the most common enterobacteria is <em>Escherichia coli</em>. They do not have a particular order of arrangement.
