If an organism expresses a recessive phenotype, can you tell the genotype? Explain your answer by giving an example.

JulijaS [17]

If it is expressing the recessive phenotype, then you know right away what thegenotype is. For example, for the recessive trait of green-colored peas versus the dominant trait yellow-colored peas. If you have green peas, then you know this plant has the homozygous recessive genotype for the pea color gene.

Raw shell eggs must be received in refrigerated equipment that keeps them at a temperature of _______ or less. A. 41°f B. 45°f C

emmasim [6.3K]

Answer:

B. 45°f

Explanation:

It is recommended that raw shell eggs must be stored at a temperature of 45°f or less because this ensures that the eggs will retain their quality over a long period of time.
The quality of the eggs is maintained below 45°f because cool temperatures help to slow the growth of several bacteria and also helps to avoid the degradation of the eggs.
The rate of degradation at higher temperatures is such that at higher temperatures the loss of quality in one day is equivalent to the loss of quality in one week when kept at temperatures lower than 45°f.

All of the following are examples of postzygotic reproductive isolating mechanisms EXCEPT Select one: a. two plant species flowe

BartSMP [9]

Answer:

a. two plant species flowering at different times.

Explanation:

The only option that is not a post-zygotic reproductive isolation mechanism would be option a, when two plant species flower at different times.

Post-zygotic reproductive isolation mechanisms are those mechanisms that act to ensure that the product of fertilization remains invalid. This is as opposed to pre-zygotic isolation mechanisms that act to prevent fertilization and hence, formation of zygotes.

In option b, c, d and e; the zygote has been formed already and all the forces are just acting to ensure that it remains invalid. whereas in option a, there is no fertilization yet.

Two plant species flowering at different times will ensure that there is no cross pollination between the two species. Without pollination, there cannot be a zygote formation.

Hence, the correct option is a.

OleMash [197]

Answer:

C. The pH is too acidic

Explanation:

Many acids and bases in living things are secreted to provide the proper pH for enzymes to work properly. Enzymes are biological catalysts, such as pepsin, which is needed to digest protein in the stomach and requires an acidic environment.

in redi's second experement, what was (a) the independant variable and what was (b) the dependant variable?

aleksley [76]

in redi's second experiment, the independent variable is presence of the gauze, or lack of it, while the dependent variable is appearance of maggots .

<h3>What are independent variable and independent variable?</h3>

independent variable can be described as the variable that stands alone and whereby the other variables can not impact it when one is trying to measure. For instance someone's age is independent variable.

On the other hand ,dependent variable are variable that can not stand alone , hence in redi's second experiment, the independent variable is presence of the gauze, or lack of it, while the dependent variable is appearance of maggots .
