which of the following is true about the Earth’s layers? A The asthenosphere is the thickest of Earth’s layers. B All of the layers are liquid and extremely hot. C There is little to no pressure on the solid core. D The Earth’s core has two different parts.
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.

how many monkeys would have to live in a 3/4sq.km. area to have the same population density as the carabao?
Answer: 20 monkeys
Explanation:
Question is lacking a very important detail which is the population density of monkeys in the Carabao.
I found that out to be 26.7 monkeys per sq.km
Population density = Number of monkeys / Area
With the population density known to be 26.7 monkeys per sq.km and the area known to be ³/₄ sq. km, the number of monkeys is;
26.7 = No. of monkeys/ ³/₄
No. of monkeys = 26.7 * ³/₄
No. of monkeys = 20

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
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.
