What change in surface area is expected to result in a faster rate of diffusion?

Answers

Answer 1
Explanation: When the cell increases in size, the volume increases faster than the surface area, because volume is cubed where surface area is squared. When there is more volume and less surface area, diffusion takes longer and is less effective.

Answers

Answer:

D

Explanation:

The Earth’s core has two different parts is true about the earth's layer.

What is Earths core?

The extremely hot and dense core of our planet is called the Earth's core. Underneath the chilly, brittle crust and the largely solid mantle is the ball-shaped core.

Earth was a homogeneous ball of hot rock when it first formed roughly 4.5 billion years ago. The ball heated up even more due to radioactive decay and heat left over after planetary formation (the collision, accretion, and compression of space rocks).

After roughly 500 million years, our young planet's temperature reached 1,538° Celsius (2,800° Fahrenheit), the temperature at which iron melts. The iron age refers to this crucial period in Earth's history.

Therefore, The Earth’s core has two different parts is true about the earth's layer.

Which type of mutation results in a frameshift mutation? Check all that apply.
substitution

insertion

deletion

point mutation

Which type of mutation adds one or more base pairs?

insertion

substitution

deletion

Answers

Insertion-deletion type of mutation results in a frameshift mutation changing the amino acid code for protein, hence options A and B are correct.

What is frameshift mutation?

A frameshift mutation is produced via insertion and deletion. "indel" mutations, which stand for insertion or deletion mutations, result in frameshift mutations.

The way the DNA is read is altered by these changes. The nucleotides that follow in a DNA sequence can all be affected by a frameshift mutation, making them more likely to have severe effects.

A frameshift mutation is brought on by insertion and deletion, mutations from insertional or deletional mutations result in frameshift mutations.

Therefore, frameshift mutations happen when one or more nucleotides are added or removed, provided that the total number of nucleotides added or subtracted does not exceed three, disrupting the normal sequence of codons, hence options A and B are correct.
