Answer:

A: Silicon

Explanation:

More than 90% of the Earth's crust is composed of silicate minerals, making silicon the second most abundant element in the Earth's crust (about 28% by mass) after oxygen. Ur Welcome.

Answer – A (Silicon)

Option A (Silicon) makes up 27.7% of the elements in the earth’s crust
Option B (Magnesium) makes up 2.1% of the elements in the earth’s crust
Option C (Nickel) is not found in earth’s crust.
Option D (Iron) makes up 5.0% of the elements in the earth’s crust

The earth’s crust basically contains eight (8) elements namely: Oxygen, Silicon, Aluminum, Iron, Calcium, Sodium, Potassium and Magnesium (Listed in order of abundance). The only element that is more abundant that Silicon in the earth’s crust is Oxygen, which accounts for 46.6%.

Rosa drew a diagram to compare substitution mutation and insertion mutations. What label belongs in the area marked "Y"?

Bezzdna [24]

Answer:

Hey There!

_____________________________________

Answer:

_____________________________________

Mutations:

Mutations are the changes produced in the nucleotide sequence of the genome.

There are four main types of mutations

Substitution

Insertion

Deletion

Duplication.

_____________________________________

DELETION:

A small segment of chromosome mat be missing. This condition is known as deletion.

For example, Normal chromosome has A B C D E F G. If deletion mutation occurs then mutated chromosome has A D E F G and B C got deleted.

_____________________________________

DUPLICATION:

In this condition, a part of chromosome present in exec ess to the normal chromosome.

For example, Normal Chromosome has A B C D E F G. If duplication mutation occurs, then mutated chromosome had A B C B C D E F G and B C is duplicated.

_____________________________________

SUBSTITUTION MUTATION:

Substitution is a type of mutation where one base pair is replaced by a different base pair.

For example, in the sequence CAAGT, if C replaces G, it is a substitution mutation.

INSERTION MUTATION:

In genetics, an insertion is the addition of one or more nucleotide base pairs into a DNA sequence.

For example, in the sequence CAAGT, if extra base G gets inserted after C, the new sequence would be CGAAGT.

_____________________________________

Both substitution and insertion mutations change the position of nucleotide thus, the type of amino acid. Option A is correct because B and D are wrong as increase in number of bases and decrease in number of bases is because of deletion and duplication mutations here it asks for substitution and insertion mutations. C is wrong as In mutation there is always a change in bases or chromosome. So all the other choices seem incorrect as it is asking for substitution and insertion the base pair changes which results in the change in type of amino acid.

Definition of Krebs cycle

Oliga [24]

The citric acid cycle – also known as the TCA cycle or the Krebs cycle – is a series of chemical reactions used by all aerobic organisms to release stored energy through the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins into adenosine triphosphate and carbon dioxide.

What would be the effect on climate in the temperate latitudes if Earth were to slow its rate of rotation from a 24-hour period

grin007 [14]

The correct option is (E) The climate would stay the same. The only change would be longer days and nights.

If Earth were to slow its rate of rotation from a 24-hour period of rotation to a 48 -hour period of rotation, the climate would stay the same. The only change would be longer days and nights.

<h3>How does the rotation of the Earth affect day and night?</h3>

Earth rotates on its axis, or turns, once every 24 hours, carrying us all along with it. We experience daylight when we are on the side of the Earth that faces the Sun. We are now on the side of the Earth that faces away from the Sun, and night has fallen.
The Earth revolves counterclockwise, and if we were to look down on it from above the north pole, we would notice that day and night move over our planet from east to west.

I understand that the question you are looking for is "What would be the effect on climate in the temperature latitudes if Earth were to slow its rate of rotation from a 24-hour period of rotation to a 48-hour period of rotation?

A) Seasons would be longer and more distinct (colder winters and warmer summers).

B) There would be a smaller range between daytime high and nighttime low temperatures.

C) Large scale weather events such as tornadoes and hurricanes would no longer be a part of regional climates.

D) Winter seasons in both the northern and southern hemispheres would have more abundant and frequent precipitation events.

E) The climate would stay the same. The only change would be longer days and nights.
