Which phrase best summarizes the theory of evolution by natural selection?A.Over extended periods of time populations change.

B.Survival is done by the strongest.

C.All life comes from life.

D.Species evolve and become better adapted to their environment.

Answers

Answer 1
Answer: The correct answer is (d.) species evolve and become better adapted to their environment. It best summarizes the theory of evolution by natural selection. It simply implies that organism changes over a period of time and evolve in a better way because of their adaptation to their environment.

What effect would an increase in temperature have on the rate of osmosis in these cells

Answers

An increase in temperature would increase the rate of osmosis in cells. This is because the higher temperature would increase the kinetic energy of the water molecules, making them move faster and more easily across the semi-permeable membrane.

The rate of osmosis is affected by a number of factors, including temperature, concentration gradient, and membrane permeability. The temperature is the most important factor, and a 10°C increase in temperature can typically double the rate of osmosis.

In cells, the water concentration is typically higher outside the cell than inside the cell. This creates a concentration gradient, which drives the movement of water into the cell. The membrane surrounding the cell is semi-permeable, which means that it allows water molecules to pass through but not other molecules, such as solutes.

Therefore, An increase in temperature would increase the rate of osmosis in cells.

Answer:

hope it helps you❤❤❤❤

Explanation: Factors Affecting the Rate of Osmosis

Temperature - The higher the temperature, the faster the movement of water molecules across the semi permeable membrane.

Osmosis is the passage of water from a low solute concentration area through a semi-permeable membrane to a high solute concentration area to equalize the solute concentrations on both sides. Meaning of the terms: solute, solvent and solution. A solvent is the base substance, where a solute is being dissolved and the result is the solution. Through osmosis, water is provided to the cells of your body; it plays a significant role in the preservation of life. It is this process that helps plants receive water and is even used in kidney dialysis.

500

250

0

You can't tell from that data.

Answers

1. Proteins

After RNA is formed, it is transported out of the nucleus and goes to the cytoplasm. From the cytoplasm, it goes into the ribosomes, where protein synthesis occurs. Together with transfer RNA (tRNA), mRNA will direct protein synthesis.


2. RNA is the direct result of DNA transcription.


Transcription is a process where DNA is transcribed into messenger RNA (mRNA). This carries all the information that will be needed to synthesize proteins.


3. Sugar and phosphates

The backbone of DNA, is made of sugar and phosphate. They form the structural framework of nucleic acids. They are arranged alternately, sugar-phosphate group-sugar and so on. The backbone refers to the sides of the DNA "ladder."


4. 500

In base pairing, guanine and cytosine pair up and adenine pairs up with thymine. Fore every adenine, there will be a thymine. If there are 500 adenine bases, there will be one for each one. So the answer is 500.

the answer of the 1st question is Proteins. (According to DNA replication and RNA process and metabolism)the answer of the 2nd question is RNA transcription takes place in the cytoplasm of a cell.the answer of the 3rd question is nitrogenous bases, sugar, and phosphates, that is proved by the sequence of each strand of DNA.the answer of the 4th question is 500 thymines, that is because each adenine bases changes to Thymine, so during DNA replication, so the number of adenine bases = number of thymines.
