Mr. Morales is teaching a lesson on classification. He says that spiders are classified as a different group than insects becaus

e they have eight legs instead of six legs. He explains that spiders evolved first. Mr. Morales also says that having eight legs is the derived trait that separates the two groups. Antonio thinks Mr. Morales is wrong. Which piece of information is Antonio considering?

antonio is considering that since the spiders came first, it cannot have 'derived traits' from anything. spiders themselves are the ancestralspecies of the insects

What is the relationship between biodiversity and number of populations?
noname [10]
Biodiversity increases as the number of populations grow, because a greater population generally means a more diverse one.

However, this is not always true, so I'm not sure what answer they're looking for.

Suppose that a scientist deletes the AAUAAA consensus sequence, the poly(A) tail, or the 5' cap from pre‑mRNAs in an mRNA. She t
Andrej [43]

Answer:

<h2>AAUAA deletion- (B ) </h2><h2> </h2><h2>Poly(A) tail deletion- (C) </h2><h2> </h2><h2>5' cap deletion-  (A) </h2>

Explanation:

(A) introns are not removed from the pre-mRNA due to 5' deletion;

(B) the pre-mRNA is not cleaved at the cleavage site due to AAUAA deletion

(C) the mRNA is not transported to the cytoplasm due to poly A tail deletion;

AAUAA deletion:  if we delete the AAUAA  sequence then there is the change of sequence of pre- mRNA that the pre-mRNA is not cleaved at the cleavage site .

Poly(A) tail deletion: Poly(A) tail is the long tail of Adenine in the 3' end of mRNA, after the deletion of Poly(A) tail, it affects the transport of mRNA from the nucleus to the cytoplasm and  the mRNA is not transported to the cytoplasm if tail is deleted.

5' cap deletion; the effect of 5' cap deletion is that introns are not removed from the pre-mRNA. The process of intron removing and exon joining is called RNA splicing.

A researcher is examining the response of corn to herbivory by white-tailed deer. She sets up a corn field with a very high fenc
stiks02 [169]

Answer:

The herbivory by the white-tailed deer

Explanation:

The independent variable can be defined as the variable that who's values do not depend on those of another.

The independent variable in this case is the herbivory by the white-tailed deer which is divided into two categories.

The dependent variables is the response of the corn to the independent variable which are measurements to be taken as shown in the question; the height of the corn plants and the number of ears or corn each plant produces.

Identify a reason why meiosis leads to significant genetic variation while mitosis does not.
liraira [26]
Because meiosis only has half of the genes.

In mitosis, the cell produced will have an exact number of chromosome like the parent cells. But in meiosis, only half of the chromosome will be given. That will make many variations since the chromosome is split in random. The process to split the gene doesn't include a process to making it move in the same manner so the gene position can be changed in the different case.
