Why are fats important to organisms?

1a. The parent is homozygote dominant and homozygote recessive where red(R) is the dominant trait and white(r) is the recessive trait. The genotype of the parents should be:

homozygote dominant= RR

homozygote recessive= rr

1b. To find the possible offspring, you need to know the possible gametes from each parent and make a punnet square with it.

RR

possible gamete= 100% R

rr

possible gamete= 100% r

punnet square of the offspring:

R

r Rr

The answer is 100% Rr

1c. Red flower is a phenotype. This because red is dominant, phenotype will be expressed when the gene is homozygote dominant or heterozygote. The offspring from the cross is 100% heterozygote, so the chance for red flower would be 100% too.

1d. White flower is a phenotype. This because white is recessive, phenotype will be expressed when the gene is homozygote recessive only. The offspring from the cross is 100% heterozygote which mean 0% chance for homozygote recessive. So the chance for white flower would be 0%.

2.
The purple stem(P) is dominant of green stem(p) and red fruit(R) is dominant over yellow fruit(r).
Both parents for the crossing is heterozygote for both traits, so the phenotype and genotype would be green stem and yellow fruit(Pp Rr)

PpRr possible gamete: PR, Pr, pR, pr
The punnet square should be 4x4 with the possible gamete above. It is hard to draw in here but the phenotype should be at 9:3:3:1 ratio

3a. Brown allele is dominant to all other traits. That means you need at least 1 brown allele to make the cat has brown eyes phenotype. The possible phenotype would be:
$C^{W}$ $C^{W}$
$C^{W}$ $C^{N}$
$C^{W}$ $C^{Y}$
$C^{W}$ $C^{B}$
The total is 4 possible genotype

3b. The grey allele is dominant to blue, but recessive to brown and green. Grey eye phenotype would need at least one grey allele, without the brown or green allele. The possible genotype would be:
$C^{Y}$ $C^{Y}$
$C^{Y}$ $C^{B}$
The total is 2 possible genotype

3c. Green eye cat will need at least green allele without brown allele. The punnet square should be:

W Y
N WN YN
Y WY YY
The phenotype of the offspring is WN(brown), WY(brown), YN(green), YY(grey). So, the chance for green eye would be 1/4 = 25%

How can scientists practice ethical lab behavior

Murljashka [212]

Answer:

Ethics refers to some set of rule and regulations or principles, that ensure the right conduct in a definite professional or academic environment.

When we talk about lab ethics, there are a set of principles which a scientist need to follow to demonstrate excellent lab ethics.While working in laboratory a scientist must make sure that ethical standards are a priority of them. Here we will discuss few of those:

A scientist should never manipulate the data and results just to make them in accordance with the previously reported studies.
Scientist should properly document every protocol and process and take special care that no changes are made in experiment due to environmental influences that can affect the reliability of results.
Scientist should always report the results and processes which he performed and never report work without actually doing it.
Scientist should never omit some part of the experiment or compromise the data or results of experiment.
Scientist should never manipulate the calculations.
Every process or step that is part of a scientist's experimentation should be conducted before the finalization of the results and not perform procedure after results are made.
Scientist should replicate his experimentation at least three times to make sure that what he is reporting is based on facts and not just error in experimentation.
Scientist should never report self made information just to validate or proof his work.

Hope it help!

Nat2105 [25]

Protein subcellular expression and molecular complexing interactions are correlated with their functional activities. With the use of fractionation techniques or fluorescence microscopy-based techniques, localization may be efficiently established.

When a signaling route is understood, it is possible to deduce a protein's function from its location. To comprehend basic biological processes, fluorescent proteins can be overexpressed inside of cells and recombined with either target proteins or regulatory areas.

Cellular protein localization is widely studied using fluorescence microscopy. Normally, time-consuming and error-prone conventional methods are used to assess images of protein sites. Therefore, automated methods are necessary for the categorization of such photos.

These techniques must be precise and efficient in terms of computing.
