B dimples

C Ff

D upturned nose

Answers

Answer 1
Answer:

phenotype is observable so A

Answer 2
Answer:

I think it has to be D definitely because an upturned nose may be a result of a genetic mutation threw the years do to a dry environment,

Hope this helps!

In which situation would a savings account be the best investment to earn interest?A.saving for retirement in twenty years
B.saving to buy a new car in three years
C.saving to buy a new house in seven years
D.saving in July to buy holiday gifts in a few months

Answers

The correct answer is C. Saving to buy a new house in seven years.

You can save to buy a house in seven years which will be profitable because you can rent the house and start returning your money which you spend on buying the land.

Saving is termed as the income which is not spend. Someone can save money by either pension account, investment fund and also deposit account.

Saving reduces expenditure, for example, recurring costs. It is closely related to physical investment.

A savings account would be the best investment to earn interest is saving for retirement in twenty years. The answer to your question is A. I hope that this is the answer that you were looking for and it has helped you.

A. A disease kills off a single species of predator within an ecosystem.
B. A wildfire burns a national park.
C. Global temperatures drop several degrees after several massive volcanic eruptions.
D. A massive earthquake strikes North America.

Answers

The correct options are as follows:
1. D.
A clade refers to a group of organisms that are made up of evolutionary descendants that originated from a common ancestor. A clade that will survive a series of catastrophic events must be one that is made up of distantly related and diverse species. This is because, those species will have different type of adaptability capacity and will be able to adapt in different ways to the catastrophic events. Due to the differences in their ability to adapt, some of the specie will survive the catastrophic events even if others are wipe out.

2. B.
The mass extinction of one specie usually creates space for another new specie to survive. The new specie that survive the old one may possess the ability to adapt to the event that wipe out the former set of living organisms and thus, the new specie will be able to occupy and reproduce in their new space. Mass extinction is said to occur when the whole population of living organism living in an ecosystem are wipe out as a result of unfavorable conditions.

3. B.
Convergent evolution refers to the independent evolution of similar features in species that arise from different lineages. The species involved usually evolve these traits as a result of having to adapt to similar environments. Convergent evolution usually result in evolution of analogous structures, that is, structures that have similar forms or functions but which are not present in the last common ancestors of the species.

4. C.
 In evolution, gradualism refers to theory that states that evolution occurs slowly and gradually, thus, large changes in evolution are actually product of small changes that occur over a long period of time. The theory of gradualism was originally proposed by James Hutton in 1795.

 5. C.
Mass extinction refers to the wiping out of a a large number of species within a very short time. Mass extinction can occur as a result of severe unfavorable conditions that all the species in an ecosystem can not adapt to. An instance of this is a drastic decrease in global temperature after several massive volcanic eruptions.

Is cytokinesis a part of mitosis

Answers

Cytokinesis is part of M-phase, but not part of Mitosis. M-phase consists of nuclear division (mitosis) and cytoplasmic division (cytokinesis). And yes, telophase is part of mitosis, so it's in M-phase too.

The central dogma of molecular biology is centered upon the process of protein synthesis, in which the information from DNA is transcribed and translated, resulting in multiple amino acids being joined to form _________ carbohydrates proteins

Answers

Answer;

Proteins


The central dogma of molecular biology is centered upon the process of protein synthesis, in which the information from DNA is transcribed and translated, resulting in multiple amino acids being joined to form proteins.


Explanation;

During the process of transcription DNA is used as a primer to produce a messenger RNA, catalyzed by the enzyme RNA polymerase. This process takes place in the nucleus of a cell.

The mRNA is transported to cytoplasm after processing or what we call splicing, to remove non-coding regions of RNA.

In the cytoplasm the process of translation takes place in the organelles called ribosomes where the tRNA with the anticodons reads the codons on the mRNA forming amino acids that are joined together to form polypeptides and proteins.


okay the answer is like this:

resulting in multiple amino acids being joined to form Proteins.

What does evaporation change from ? Solid ———> liquid Liquid ———-> Solid What does condensation change from Liquid——-> solid Solid———> liquid

Answers

Answer:

Evaporation : Liquid --- Gas (Vapor) ; Condensation : Gas (Vapor) --- Liquid

Explanation:

Evaporation is the change of a liquid into gas or vapor, usually by increase in temperature. Eg : Water evaporation into vapors during water cycle, due to sun heat.

Condensation is the change of gas or vapor into liquid, usually by decrease in temperature. Eg : Vapors condensation into water droplets during water cycle, due to lower atmospheric temperature at higher height.

Answers

Good evening Aixa,

An experiment is designed so that you can observe the differences between the experimental group and the control group.

The experimental group is the group of specimens you're exposing to the experiment and the control group is a separate group of specimens that is not being exposed to the experiment, but are also being observed.
