Answer:
Natural selection occurs in opposition to evolution. Natural selection favors individuals that reproduce more than others.
Explanation:
Michael and Jose are studying about plate tectonics. They learned that plates usually move a few centimeters every year. They learned that the movement of heated material caused the plates to move. In which layer does the heated material move?
Answer:
Mantle layer
Explanation:
The movement of heated materials on the mantle layer of the earth helps in the movement of the tectonic plates. The earth is made up of four layers and they are the crust, the mantle, the outer core, and the inner core. The tectonic plates are always in motion which is very slow but constant.
The convection currents emanating from the mantle layer of the earth aids the movement of the tectonic plates. Natural disasters like earthquakes can result from the intense pressure emanating from the movement of the plates.
Are eukaryotes more closely related to bacteria or to archaea? Explain.
Hello!
The Answer Is: Bacteria and Archaea are comprised exclusively of microorganisms; plants, mammals, and microorganisms such as fungi and protists are contained in the Eukarya. Because of their lack of a nucleus, the Bacteria and Archaea were grouped together and called Prokaryotes, but the Archaea are more closely connected to the Eukaryotes than to the Bacteria. The cell walls of bacteria contain a compound called peptidoglycan, while the cell walls of archaea do not. Archaea and bacteria also vary because the composition of the cell membranes of archaea is peculiar and does not contain the same lipids, or fats, present in other species' cell membranes.Thank you for asking this question!

5. Why are metamorphic rocks formed by contact metamorphism usually not as dense as those
formed by regional metamorphism?
Answer:
The rock was altered by high temperature with extreme pressure
Explanation:
Fossils would be destroyed
Metamorphic rocks formed by contact metamorphism are usually not as
dense as those formed by regional metamorphism because of their mode of
formation which involves a higher temperature without little or no pressure.
Contact metamorphism involves rock formation as a result of contact with
hot magma. The regional metamorphism involves the formation of rocks
deep in the soil through extreme temperature and pressure over a wider
area.
This is the major reason why the metamorphic rocks from contact
metamorphism are denser than the regional metamorphism.

What is the importance of cell membranes to supporting life?
Answer:
The plasma membrane, or the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell. And that membrane has several different functions. One is to transport nutrients into the cell and also to transport toxic substances out of the cell. I hope this helps you :)

A cell removes a toxin it has produced through a chemical reaction. Which characteristic of living things is the cell demonstrating?
the ability to maintain homeostasis
the ability to maintain homeostasis
the ability to grow and develop
the ability to grow and develop
the ability to adapt and evolve
the ability to adapt and evolve
the ability to reproduce
Answer:
Sweating helps the human body maintain homeostasis by cooling the body when it starts to overheat so the internal temperature is kept more or less the same. When sweat evaporates from the skin, it uses up some of the excess heat energy on the skin, thus helping to keep the body cool.
According to cell theory, all living things are made of cells, and living cells come only from other living cells. Gene theory states that the characteristics of living things are controlled by genes, which are passed from parents to their offspring.
Sample answer: The concentration of oxygen in the atmosphere is maintained at 21 percent by a balance between two opposing processes: removal of oxygen from the atmosphere by most living things and addition of oxygen to the atmosphere by living things such as plants.
Sample answer: The human ability to sweat is an adaptation that helps maintain homeostasis in a hot environment by removing heat from the body when it evaporates. Like other adaptations, the ability to maintain homeostasis by sweating evolved by natural selection sometime in our evolutionary past.
a. Gene theory
b. Homeostasis
B
An adaptation is a trait that helps a living thing survive and reproduce in a given environment. Sample example. The chameleon’s ability to change color to match their background is an adaptation.
False
False
Humans began life as a single cell because we develop from a fertilized egg cell.
Gene theory states that genes are passed down from parents to their offspring. Genes determine the characteristics or traits of an organism. If these traits are particularly beneficial or adaptive, natural selection will cause the organisms with beneficial traits to produce more offspring compared to those without the beneficial traits. This results in a change in traits over time, which is called evolution.
No. Evolution is defined as a change in the characteristics of living things over time. Evolution through natural selection causes differences in the amount of offspring produced. Having offspring (or not) is, by definition, more than one generation.
Sample answer. I think that when ancestors of chameleons could change their color to match their background, they were less likely to be detected and killed by predators than those that couldn’t change their color. Therefore, the individuals that had the color matching ability were more likely to survive and reproduce than those that didn’t. This is an example of natural selection. Over time, this led to the population evolving the color changing ability, as those that didn’t have the ability died out.

Which of the following is not a function of nucleic acids during the transcription and translation processes?
O Carry genetic information from the nucleus to ribosomes
O Serves as the source of information that remains secure in the nucleus
O Carries amino acids that are bonded together to form proteins
O Forms the nuclear envelope to protect genetic material
Answer:c
Explanation: not me looking for the answers and finding you here
The principal RNA involved in protein synthesis is tRNA rather than the mRNA that is produced during transcription, which is carried from the nucleus into the cytoplasm to the ribosome. Thus, option C is correct.
What is a function of nucleic acids?A DNA strand serves as a template for the construction of the RNA molecule during transcription. The protein synthesis process and DNA are connected by the RNA molecule.
The RNA molecule produced during transcription transmits data from the DNA to the machinery that makes proteins during translation.
Because they control the creation of proteins, nucleic acids—the primary information-carrying molecules of the cell—determine the inherited traits of every living creature.
Deoxyribonucleic acid (DNA) and ribonucleic acid are the two primary types of nucleic acids (RNA).
Therefore, carries amino acids that are bonded together to form proteins is not a function of nucleic acids.

a man is twice as old as his son.Five years ago the ratio of their ages was 9:4.Find the sum of their ages
Answer:
75years
Explanation:
Let the Father's age be represented by 2x
Let the Son's age be represented by x
Five years ago;
Man's age will be = 2x - 5
Son's age will be = x - 5
If the ratio of their ages five years ago was 9:4, then;
2x - 5/x-5 = 9/4
4(2x - 5) = 9(x - 5)
8x - 20 = 9x - 45
- Collect like terms
-20 + 45 = 9x - 8x
25 = x
Hence, the son's age = 25 years
If x = 25, the father's age (2x) will be 2 × 25 = 50years
The sum of their ages will be = 25years + 50years = 75years

A balloon is filled with helium in an airplane, where the air pressure is 81 kPa. The filled balloon has volume of 4.2 L. When the plane lands, the cabin is depressurized to the outside air pressure, which is 94 kPa. If the temperature of the balloon remains the same, what is the new volume of the balloon?
Answer:
3.62L
Explanation:
Using Boyle's law equation i.e
P1V1 = P2V2
Where;
P1 = initial pressure
V1 = initial volume
P2 = final pressure
V2 = final volume
According to information provided in this question, P1 = 81kPa, P2 = 94kPa, V1 = 4.2L, V2 = ?
P1V1 = P2V2
81 × 4.2 = 94 × V2
340.2 = 94V2
V2 = 340.2/94
V2 = 3.619
V2 = 3.62L
