2. Describe the trans-<br>formation of energy<br>that occurs during<br>photosynthesis.<br>​
Viefleur [7K]

Answer:

Explanation:

Photosynthesis is the process plants use to convert energy from the sun into usable energy for their cells. Plants use the light energy of the sun, carbon dioxide, and water to make glucose (a sugar), and oxygen. The energy of the sun is captured and stored in the bonds between atoms in glucose molecules.

A bacterial sample has a cell density of 1.85 x106 CFU/mL. What plate dilution should yield a countable plate? Which two dilutio
insens350 [35]

Answer:

Explanation:

Bacterial count in stock- 1.85x10^6 cfu/ml

Dilution methods

Take 100 uL or (0.1ml) from stock and add to 900ul (0.9ml) saline and mixed it- this makes 10^1dilution.

Now take 100ul from 10^1 dilution and add to next 900ul saline this is 10^2 dilution, similarly do upto 10^5 dilution.

Then take 100ul from 10^ 4 and 10^5 dilution seperately and plate on LB agar plate seperetely and count the colonies.

Cfu/ml formula= (No.of colonies x dilution factor)/0.1 ml

So suppose, 18 colonies formed on 10^4 dilution then total no. Of cells in stock will be 18x10^4/ 0.1= 18x10^5 cfu/ml.

If we dilute 10^4 or 10^5 that's leads to colony count of 18-19 colonies on 10^4 dilution while 2 colonies should come on plate of 10^5 dilution.

What is the definition of epistasis?
ollegr [7]

The definition of Epistasis in gene biology is Choice D: when the allele of one gene masks the phenotype of another gene

Definition:

When the phenotypic effect of alleles at one gene are masked by alleles of another gene.

In essence, a gene is said to be epistatic when its presence suppresses the effect of a gene at another locus.

It is important to know that Epistatic genes are often called inhibiting genes because of their effect on other genes which are described as hypostatic.

Additionally, there are six common types of epistasis gene interactions:

  • Dominant

  • Dominant inhibitory,

  • Duplicate dominant,

  • Duplicate recessive,

  • Polymeric gene interaction,

  • Recessive.

Wilma and Stanley are expecting their first child, and a prenatal test indicates that the child has a chromosomal abnormality. T
rodikova [14]

Answer:

The cells analyzed might be a mosaic of different genomes

Explanation:

The human genome in every cell might not be the same and could give us some misrepresentation of what really happens on our genome. Chromosomal abnormalities are also a very common phenomena to be observed in human cells. For those differences in the genome of the child the test might have identified some altered cells with a type of chromosomal abnormality which was not latter identified or the abnormal cell might be also eliminated by its abnormal nature.
