They have to have a higher density than water to have the ability to stay on the sea floor. Otherwise they would just float to the surface of the water
Answer:
Plasma and Platelets
Explanation:
These are the two main components that make up blood.

Stem cells are the body's raw materials — cells from which all other cells with specialized functions are generated. Under the right conditions in the body or a laboratory, stem cells divide to form more cells called daughter cells.Research carried out with the use of these cells has demonstrated their effectiveness in the treatment of various diseases, such as leukemia, heart disease and hematological diseases. Embryonic stem cells, in turn, have the ability to form any tissue in the body.
<h3>How are embryonic stem cells used?</h3>
Stem cells have the ability to differentiate and self-renew. For this reason, they can be used in the treatment of degenerative diseases. Stem cells stand out for their ability to transform into different cell types, that is, they are cells with a great capacity for differentiation.
<h3>What diseases could be treated with the use of Embryonic Stem Cells?</h3>
- Diseases that can be treated with stem cells
- leukemias. Leukemia is a generic term used to describe the “cancer” of leukocytes, the white blood cells.
- Thalassemias.
- Neuroblastoma.
- Primary immunodeficiencies.
- Sideroblastic anemia.
- Metabolic diseases.
- Sickle cell anemia.
With this information, we can conclude that Scientists are also working on ways to develop stem cells from other cells, using genetic “reprogramming” techniques.

Answer:
The ratio of blue to white offspring in the progeny is 4 blue : 12 white.
Explanation:
<u>Available data:</u>
- The dominant allele K is necessary to synthesize blue flower pigment
- K is inhibited by the dominant allele D
- Plants with the genotype K- D- will not produce pigment (and their flowers will be white)
Cross: testcross for (Kk Dd) plants
Parental) KkDd x kkdd
Gametes) KD kD Kd kd
kd kd kd kd
Punnet square) KD Kd kD kd
kd KkDd Kkdd kkDd kkdd
kd KkDd Kkdd kkDd kkdd
kd KkDd Kkdd kkDd kkdd
kd KkDd Kkdd kkDd kkdd
- Whenever D is present, it inhibits the expression of the K gene, so every plant with the dominant D allele will be white. This plants´ genotype is kkD- or K-D-.
- Whenever D is absent and K is present, every plant with genotype K-dd will be blue.
- The recessive form for K and D genes will express white-flowered plants, with genotype ddkk
F1) Progeny genotype: 4/16 KkDd, white-flowered plants
4/16 Kkdd, blue-flowered plants
4/16 kkDd, white-flowered plants
4/16 kkdd, white-flowered plants
The ratio of blue to white offspring in the progeny is 4 blue : 12 white.
Blue-flowered plants: 4 Kkdd
White-flowered plants: 4 KkDd + 4 kkDd + 4 kkdd
Answer:
Explanation:
Scenario 2: R is codominant with r.
Scenario 3: R and S are completely dominant to rand s, respectively; R and S are linked by 15 m.u. and do not interact with each other.
Scenario 4: Genes R and S perform the same function; R and S are completely dominant to r and s, respectively; and R and S are unlinked.
Scenario 5: R and S are completely dominant to r and s, respectively; R and S are linked by 10 m.u. and show dominant epistasis.
