When considering the evolutionary tree of life and the three domains of life, which statement best describes what likely happene
Fudgin [204]

Answer:

The answer is - Although their cell structures are very different, archaean and  eukaryotic cells are more closely related to each other than to  bacteria, as evidenced by the fact that Bacteria was the first  domain to split from the shared ancestor of Archaea and  Eukarya.

Explanation:

The options are:

A. Bacterial and eukaryotic cells are more closely related to  each other than to archaeans, as evidenced by the fact that  bacteria and eukaryotes do not inhabit the most extreme  environments.

B. Although their cell structures are very different, archaean and  eukaryotic cells are more closely related to each other than to  bacteria, as evidenced by the fact that Bacteria was the first  domain to split from the shared ancestor of Archaea and  Eukarya.

C. Bacteria and archaeans are more closely related to each other  than to eukaryotes, as evidenced by their cell structures. Bacteria  and archaeans are prokaryotic, while all eukaryotic cells contain  mitochondria and other membrane-bound organelles.

D. The three domains of life are equally divergent from one  another, so no two domains are more closely related to each other.  This is supported by the evolutionary tree of life because three  branches extend from one node millions of years ago.

The answer is - B. Although their cell structures are very different, archaean and  eukaryotic cells are more closely related to each other than to  bacteria, as evidenced by the fact that Bacteria was the first  domain to split from the shared ancestor of Archaea and  Eukarya.

Archaea and bacteria are similar in terms of cellular organisation and size but are however similar to eukaryotes (eukarya) at the molecular level. Archaea and Eukaryotes both undergo DNA replication and protein synthesis the same mechanism. Both of them posses closely related genes and several metabolic pathways, including the enzymes in transcription and translation.

Helppp, i’m going to fail:(
Westkost [7]
Don’t worry this is pretty easy :)

The answer is -
50% recessive alleles
50% dominate alleles

explication- find out what alleles you’re working with (heterogeneous and homogeneous)
[heterogeneous is 1 dominant and 1 recessive- homogeneous is 2 of the same alleles they can be dominant or recessive]
We’re working with a parent with heterogeneous and another parent with recessive homogeneous.

draw a allele chart
__
|_|_|
|_|_|
they look like this and take your first parents alleles and put them at the top

L s
_ _
|_|_|
|_|_|

it should look like this, then take your parent with both recessive and put them vertical to the box

L s
_ _
s |_|_|
s |_|_|

it should look like this, now you drag one letter down and one letter across for each box

L s
__ __
s|Ls|ss |
s|Ls|ss |
— —
it’s should look like this when they’re done, i think you’re doing a grade below me in biology so the ratio should be 50/50 for both phenotype and genotype.

TRY TO LEARN THE VOCABULARY IT HELPS A LOT AND BASICALLY TELLS YOU THE ANSWERS!
GOOD LUCK :)

For the following question, match the key event of meiosis with the stages listed below. I. Prophase I V. Prophase II II. Metaph
Andrei [34K]

Answer:

VII. Anaphase II

Explanation:

During metaphase II, fibers of the spindle apparatus drive chromosomes to the cell equatorial plane, where they line up. Sister chromatids are holden together until they reach <u>Anaphase II</u><u>,</u> during which specialized enzymes break the bonds between chromatids and separate them. Each chromatid migrates to one of the poles. In telophase II, the new chromosomes are already in the corresponding poles, and the nuclear membrane forms again in each pole
