3. Asexual reproduction requires only one parent and produces identical offspring, while sexual reproduction requires two parents and produces non-identical offspring.

Explanation:

Asexual - one parent only. Offsprings looks identical

You could see that in plants and flowers where each offspring looks the same

Sexual - two parents. Offsprings do not look identical

Ex : Animals and humans. We need a male and a female/ egg + sperm. The offsprings produced are non identical as genes from both parents are included

Answer:

Explanation:

asexual requires only one parent (think Jurrasic park lost worlds with the girl and the velociraptor they both are products of asexual reproduction)

sexual requires two parents to make the baby

Based on the thin layer of sediment on his flooded farm,
James Hutton concluded that strata:
A Are made of large rocks
B
Settle in vertical layers
C
Are formed by catastrophes like floods and earthquakes
D
Take many thousands of years to form

Answers

Answer:

D. Take many thousands of years to form

Explanation:

James Hutton discovered thin layers of sediments on his flooded farm and he concluded that strata was part of the earth surface in the past and thus takes many thousands of years to form.

This led to the principle of uniformitarianism which states that the geologic processes now are the same with the ones in the past.

The passive movement of particles from a region of higher concentration to a
region of lower concentration is known as...
A. Diffusion
B. Active Transport
C. Osmosis
D. Selective Permeability

Answers

Answer:

Answer is A. Diffusion

Explanation:

Because diffusion is a passive process in which a substance moves from a higher concentration to a lower concentration until the concentration becomes equal

The passive movement of particles from a region of higher concentration to a region of lower concentration is known as diffusion. Thus, the correct option is A.

What is Diffusion?

Diffusion may be defined as the passive movement of particles from a region of higher concentration to a region of lower concentration.

Active transport requires energy for the movement of particles. Selective permeability may be defined as the ability to differentiate the movements of different types of particles in and out of the membrane.

Therefore, the correct option for this question is A.

During cellular respiration, cells convert the energy stored in glucose to make the energy molecule ATP, as shown in the equation. Less than 40% of the energy found in glucose is actually converted into ATP. What happens to the other 60% of this energy

Answers

Answer:

the other 60% of energy is stored away for further use in the cell

Explanation:

i hope im right

In the cell from glucose, 40% of energy is utilised to make ATP and the rest 60% is used in the process of making ATP. So 100% of glucose cannot be converted into ATP.

How does ATP form from glucose?

Glucose is a major source of energy. It has carbon, oxygen, and hydrogen . Due to the presence of oxygen, it can easily break down to produce energy during times of need.

Glucose is broken down into pyruvate by the process of glycolysis. In this process, the net gain is 2 ATP. Pyruvate converts into acetyl CoA. ATP is required in this process. Acetyl CoA enters the Krebs cycle.

To enter the mitochondria, ATP is required. Acetyl CoA enters the krebs cycle and electron transport chain.  The FADH₂ , NADH are broken. Proton gradient is formed due to the electron movement. Then ATP is formed due to the proton gradient across the inner mitochondrial membrane . To make ATP a lots of ATP have used in the process. So net gain of ATP of a glucose is 40% as rest 60% has used in the process .

Hence, 40% of energy of glucose make ATP, and the rest 60% is used in the process of making ATP.
