What are the cons of fetal stem cells

Biology
2 answers:
Maslowich3 years ago

Answer:

The research is unethical(fetal stem cells) since the blastocyst, an unimplanted human embryo at the sixth to eighth day of development, is destroyed during the stem cell extraction process.

Answer:

Embryonic Stem Cell Disadvantages

1. Difficult to differentiate uniformly and homogeneously into a target tissue. 2. Immunogenic—ES cells from a random embryo donor are likely to be rejected. after transplantation.

Explanation:

The main disadvantage with embryonic stem cells is the way that they are acquired. Since human embryos are destroyed during the process of harvesting embryonic cells, this makes the research unpopular with those that believe human life begins at conception and that this life is being destroyed.

In a mark–recapture study to estimate the size of a rodent population, researchers catch and mark 30 individuals. Two days later
tatyana61 [14]

Answer: The estimated size of the population is 150

Explanation: For the Mark-Recapture method, there is a formula that can be used:

N = (M × C)/R

where :

N = estimated number of individuals in the population

M = number of individuals captured and arked

C = total number captured the second time (with and without a mark)

R= number of individuals ecaptured (those with a mark)

So with this formula we can calculate an estimation of the population of rodents. Because there is no number of rodents captured the second time given, we will assume 30 was caught again, making the 20% found marked being 6. We calculate it as:

N = (M × C)/R

:N = ( 30 × 30)/ 6

:N = 900/6

:N = 150 estimated rodents in the population

Identify one energy rich molecule that is produced during during photosynthesis
alexandr1967 [171]

Explanation:

Glucose is produced during photosynthesis.

Photosynthesis is a chemical pathway that’s integral to producing energy in plants and other primary producers. Energy in the form of molecules of glucose is produced from light, water and carbon dioxide while oxygen is released. This occurs in several complex steps, photosynthesis is a rate limited reaction, depends on several factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent.

Water supplies the chlorophyll in plant cell with replacement electrons for the ones removed from photosystem II. Additionally, water (H2O) split by light during photolysis into H+ and OH- acts as a source of oxygen along with functioning as a reducing agent; it reduces the molecule NADP to NADPH by providing H+ ions. NADP and NADPH are integral to the Calvin cycle where monosaccharides or sugars like glucose are produced after the modification of several molecules.

<em>overall: 6CO2 + 6H20 + (light energy) → C6H12O6 + 6O2</em>

Carbohydrates like glucose function to supply energy and support molecules they consist of mainly sugars or starches in long chains and rings to form monosaccharide monomers. They include monosaccharides, disaccharides and polysaccharides which describes the type of bonding and the degree of complexity of the polymers.

<em>Basic makeup: C, H, O -with many polar OH groups</em>

Most nonsense mutations in genes that encode structural proteins cause a null ("knockout") phenotype.
cestrela7 [59]
  1. TGA (opal)

Answer:

Explained below

Explanation:

A mutation in a gene that results in total loss of the normal function of the gene product encoded by that gene, resulting in a Null phenotype.

Changes in DNA sequence are termed as nonsense mutation that introduce a stop codon, resulting in a non functional protein. This terminology results stop codons have also worked as nonsense codons.

There are three different stop codon-

In RNA

  1. UAG (amber)
  2. UAA (ochre)
  3. UGA (opal)

In DNA

  1. TAG (amber)
  2. TAA (ochre)
  3. TGA (opal)
