+/+ = mutualism
+/0 = commensalism
+/- = parasitism or predation
Answer:
Visible light
Explanation:
Photosynthesis is a unique phenomenon in which plants use sunlight energy, which is a type of electromagnetic radiation, to manufacture their food. During this process, certain pigments in the leaves of plants called CHLOROPHYLL absorbs the blue and red wavelengths of light ranging from 400nm - 700nm.
However, these wavelengths of light (blue and red) that are used during the photosynthetic process are found in the VISIBLE LIGHT PORTION of the electromagnetic spectrum. The visible light is the only part that can be made use of by photosynthetic pigments.
Answer:
96
Explanation:
This is genetic drift question, we can tell because the variable here is the population size. The probability of an allele of getting fixed is determined by its initial frequency, which is actually the probability of the allele of being fixed. So we need to calculate the initial allele frequency of this mutation:
Mutation allele frequency = # mutation alleles / total # of alleles = 1/24 = 0.04%
That is the probability of this allele to get fixed, so the probability of this allele getting eliminated is:
Elimination probability = 1 - fixing probability = 1- 0.04 = 0.96%
Answer: The probability of this allele getting eliminated is 96
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.
