Imagine a genomic researcher who is analyzing the genome of different types of cats. She finds that a particular sequence in the

North American Bobcat genome is exactly homologous to a sequence found in the common house cat, while all other sequences in those two genomes differ at many nucleotides. (The most recent common ancestor between bobcats and house cats is estimated to be about 6.8 million years, plenty of time for mutation to generate DNA sequence variation.)
Which of the following could explain the identical sequence in these otherwise differing genomes?

01. The sequence encodes a ribosomal protein that is critical for life and can not be easily mutated while retaining function.

02. The sequence is contained in a virus that has infected germline cells in both species.

03. The sequence is from an intron of a gene that encodes a muscle protein.

Provide a rationale for why each of the three statements above are correct or incorrect.

<h2>Events in Development of Plants</h2>

Explanation:

The events in the development of plants is as follows:

1. Cyanobacteria begin to photosynthesize.

Cyanobacteria which are commonly called as Blue green algae are Prokaryotes.

They are aquatic and photosynthetic, it means, they live in the water, and can manufacture their own food.

2. Cyanobacteria become the chloroplast of plants.

Cyanobacteria have the endosymbiotic plastid. Eukaryotes or plants considered to have evolved from endosymbiotic cyanobacteria.

3. Bryophytes become the first land plants.

Bryophytes are the first land plants to be evolved from aquatic plants, specifically green algae.

4. Plants evolve to have vascular tissue to transport water.

During the evolution of plants from Bryophytes to Pteridophytes, Pteridophytic  plants have vascular tissue i.e. xylem and phloem. Xylem helps in transport of water to various parts of the plants.

The results of the punnet square show that one out of 16 offsprings will have both the qualities of having terminal flowers and being a dwarf.

A punnet square can be described as a diagram which depicts the likely outcomes of a cross. In the above punnett square, for the plants to have both terminal flowers and to be dwarf, both the alleles should be recessive for the traits.

The three major arteries of the upper limb that form a continuum are the Select one: a. brachial, radial, and ulnar arteries. b.
OverLord2011 [107]

The three major arteries of the upper limb that form a continuum are the subclavian, axillary, and brachial arteries. That is option D.

<h3>Arteries of the upper limbs</h3>

The upper limb is made up of the following the upper arm, forearm, and hand.

The major arteries that supply oxygenated blood to the upper limbs is the subclavian, axillary, brachial, radial, and ulnar arteries.

The subclavian, axillary, and brachial arteries are said to form a continuum because they are continuous with one another.

Therefore, the three major arteries of the upper limb that form a continuum are the subclavian, axillary, and brachial arteries.

Hemophilia is a condition in which blood does not clot naturally, and a person with hemophilia could bleed to death if injured.
barxatty [35]

As we know our blood has four main components which are plasma, red blood cells, white blood cells and platelets. That is why a hemophiliac must receive regular injections of platelets to stay alive. This is done by injecting into their bloodstream human plasma which contains many proteins, glucose, clotting factors, electrolytes, hormones, and carbon dioxide.
