Why would you expect an earthworm to lack an exoskeleton??

Biology
1 answer:
Murrr4er [49]3 years ago

You would expect an earthworm to have no exoskeleton because as you see it is very flexible and soft. Organisms with such have body parts that are divided and an earthworm do not have any visible parts on them also having an exoskeleton would not allow an organism to move like an earthworm does.

Which two processes that occur during the formation of gametes contribute to increasing diversity within a populations gene pool
yanalaym [24]

Answer:

1) Crossing over

2) Independent assortment.

Explanation:

Gametes are formed resulting from the process of meiosis where the gametes get half of the original number of chromosomes. One phenomenon that happens during the prophase 1 of Meiosis and leads to the genetic diversification is crossing over. In this process , Here, homologous chromosomes pair up and exchange information present on genes from one another. When information is exchanged, it leads to the diversity of genetic data.

The second way of increasing genetic diversity is independent assortment that takes place during metaphase 1. In this process chromosomes from both father and mother cells align on equatorial plate of the cell in an independent manner. This means that some gamete can have 1 of many different chromosomal combinations.

This reshuffling of chromosomes during independent assortment enhances the genetic diversity of any organism and this also explains why kids of same parents can look or behave very different.

Hope it help!

Survival of the fittest definition biology
olya-2409 [2.1K]

Answer:

"Survival of the fittest" is a phrase that originated from Darwinian evolutionary theory as a way of describing the mechanism of natural selection. The biological concept of fitness is defined as reproductive success.

Explanation:

The Darwinian evolutionary theory was created by Charles Darwin.

Darwin published his theory of evolution with compelling evidence in his 1859 book On the Origin of Species, overcoming scientific rejection of earlier concepts of transmutation of species. By the 1870s, the scientific community and a majority of the educated public had accepted evolution as a fact.

Male-patterned baldness is more common in males as the name suggest.why is this?
Ray Of Light [21]

Answer:

mark brainliest :))

Explanation:

Because baldness is a sex-linked trait.  

In other words, men are simply more likely to express the trait for baldness than women are, because they only need one set of genes for baldness, while women need two.  

If, for example, for each gene there is a 1/2 chance that the gene will be for baldness and 1/2 that it will not, then men have a 1/2 chance (because 1/2^1 = 1/2) of being bald, while women have a 1/4 chance (because 1/2^2 = 1/4) of being bald.  

This is the reason it's called "male-pattern baldness": it is more common in males. However, this does not explain nor rule out the dearth of women with baldness-women can get it too: it's just less common

How does the genotype of a bacterium determine its phenotype? Use the terms gene, mRNA, ribosome, and polypeptide in your answer
tensa zangetsu [6.8K]
Typically, the genotype is encoded in the DNA by the gene; this gene in the DNA will then undergo the process of transcription and the information in the gene will be transcripted into mRNA. The mRNA will then undergo the process of translation and the information in the mRNA will  be translated into a polypeptide chiefly by the action of ribosome. Thus, bacteria with different genotypes will have different protein which automatically means that they will have different phenotypes.
