Answer:
freezes. melts/thaws
Explanation:
In frost wedging, a crack expands when water freezes. When the water melts/thaws it can seep into new fissures in the rock.
What is frost wedging?Water that seeps into cracks and freezes expands, resulting in frost wedging also known as ice wedging. The growth causes the fissures to widen. How often something freezes and thaws affects how effective frost wedging is.
During the "frost wedging" process, water seeps into rock fractures, causing the gaps to widen when the water expands upon freezing. The effectiveness of frost wedging is influenced by how frequently it freezes and thaws.
Frost wedging is a type of physical weathering in which rocks are degraded by the cycle of freezing and thawing.

A generalist predator does which of the following
Answer:
Predators are an important part of a healthy ecosystem. Predators remove vulnerable prey, such as the old, injured, sick, or very young, leaving more food for the survival and success of healthy prey animals. Also, by controlling the size of prey populations, predators help slow down the spread of disease.
5 A prokaryotic cell is 5.0 um in length. A virus particle is 300 nm in length. How many times larger is the prokaryotic cell compared to the virus particle?
A 2
B 17
C 60
D 167
The prokaryotic cell is 17 times larger as compared to the virus particle.
Both values first need to be converted to the same unit.
5.0 um = 5.0 x [tex]10^-^6[/tex] m
300 nm = 3.0 x [tex]10^-^7[/tex] m
Dividing both values:
5.0 x [tex]10^-^6[/tex] m/3.0 x [tex]10^-^7[/tex] m
= 16.667
Hence, the prokaryotic cell is approximately 17 times bigger than the virus particle.

birds and mammals are both endothermic. i.e. they maintain body temperature internally through metabolism rather than from the environment. how would you explain this, given the position of the two groups of animals on the phylogenetic tree?
On the phylogenetic tree, (a diagram used to show relatedness among organisms) the birds and mammals are closely related to each other and they both are characterized as endothermic.
Given the position of the two group of animals on the phylogenetic tree, their similarity with regards to maintaining body temperature is due to the fact that their evolution involves a more recent ancestor compared with the other vertebrates.
As organisms evolve beginning from invertebrates through to vertebrates, the body system becomes more complex and as they evolve within the vertebrate group.
Some vertebrates like reptiles and amphibians that were dependent on the environment to regulate their temperature while others like birds and mammals forms complex system that enable them live on land and regulate their temperature independent of the environment.

Can a virus cause a change in your DNA?
Please answer this don’t just take the points please I need help
Answer:
Yes , when viruses infect us, they can embed small chunks of their genetic material in our DNA. Although infrequent, the incorporation of this material into the human genome has been occurring for millions of years. As a result of this ongoing process, viral genetic material comprises nearly 10 percent of the modern human genome. Over time, the vast majority of viral invaders populating our genome have mutated to the point that they no longer lead to active infections. But, as scientists funded by the National Institutes of Health have demonstrated, they are not entirely dormant.
Explanation:
Answer:
Viruses are continuously changing as a result of genetic selection. They undergo subtle genetic changes through mutation and major genetic changes through recombination. Mutation occurs when an error is incorporated in the viral genome. Recombination occurs when co infecting viruses exchange genetic information, creating a novel virus.
so i will say YES

BRAINLIEST?Which of the following choices best describes ‘ovulation?'
A. An egg is released from the ovary.
B. An embryo sinks into the uterus lining.
C. The sperm and egg nuclei fuse.
D. The ejection of sperm through the penis.
Answer:
An egg is released from the ovary
Ovulation is a crucial process in the female reproductive system, occurring as a part of the menstrual cycle. It involves the release of a mature egg (ovum) from one of the ovaries. The correct option is A. An egg is released from the ovary.
1. **Menstrual Cycle**: The menstrual cycle is the regular hormonal cycle that occurs in women of reproductive age. It typically lasts around 28 days, although the length can vary from woman to woman. The cycle is divided into different phases, with ovulation occurring during one specific phase.
2. **Follicular Phase**: The menstrual cycle begins with the follicular phase, where hormones, primarily follicle-stimulating hormone (FSH) and luteinizing hormone (LH), are released by the pituitary gland. These hormones stimulate the growth and maturation of follicles in the ovaries.
3. **Ovarian Follicles**: Within the ovaries, multiple tiny sacs called ovarian follicles contain immature eggs. Each month, one of these follicles becomes dominant and continues to grow while others degenerate.
4. **Mature Follicle Development**: As the dominant follicle grows, it secretes estrogen, a hormone that prepares the uterus for a potential pregnancy. The rising estrogen levels also trigger a surge in luteinizing hormone (LH) around the middle of the menstrual cycle.
5. **Ovulation**: The LH surge triggers the final stage of ovulation. It causes the mature follicle to rupture and release the mature egg from the ovary. The egg is swept into the fallopian tube by tiny hair-like structures called cilia.
6. **Fertilization**: The released egg remains viable for about 12-24 hours. If sexual intercourse occurs during this time and sperm are present in the fallopian tube, fertilization may occur. Fertilization is the process where the sperm penetrates the egg, resulting in the formation of a zygote (fertilized egg).
7. **Implantation or Menstruation**: If the egg is not fertilized, it will eventually disintegrate, and hormone levels will drop. This leads to the shedding of the uterine lining, causing menstruation to occur. On the other hand, if fertilization occurs, the resulting zygote will undergo several divisions and travel down the fallopian tube to the uterus, where it may implant into the uterine lining and develop into a pregnancy.
Ovulation is a crucial event in the female reproductive cycle, marking the release of a potential egg for fertilization. It is a key factor in determining fertility and the ability to conceive a child.

change?
Increased fire and drought
Increased pollution
Displaced inbes
Habitat fragmentation
Answer:
Increased pollution is your answer!
Explanation:
Increased pollution is your answer because:
1. ⇒ Burning of mostly anything creats, and all the materials in the forest are one of those materials that will create smoke. And smoke is made out of carbon dioxide, and other poisonous gases that are very bad for our atmosphere.
2. ⇒ The damage from the fire will also cause a lot of damage to the trees and plants. That is very bad because trees are very important for our environment, in their leaves, they have a chemical called chlorophyll, this chlorophyll absorbs sunlight and turns it into oxygen. Not only sunlight is needed, there is also, water, nutrients needed.

Question 4 of 10
Newton's second law of motion states that the acceleration of an object
depends on the force exerted on it, divided by its mass. This law can be
summarized by the equation F = mx a.
Why is this a law and not a theory?
A. Newton's statement involves mathematics. A theory is a
description based on observations,
OB. Newton's statement describes the relationship between mass,
acceleration, and force. A law is an explanation of natural events.
O C. Newton's statement is supported by research. A theory is only an
educated guess
D. Newton's statement has been proved with scientific evidence. A
theory can change when new evidence is found that does not
support the theory
SUBMIT
The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object. The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object.

True or false: Theoretically, it is possible (but very difficult) for a population to not evolve for a while.
It is true that it is possible for a population to not evolve for a while.
There is something called the Hardy-Weinberg theorem, which characterizes the distributions of genotype frequencies in populations that are not evolving.
There are 5 Hardy-Weinberg assumptions:
no mutation random mating no gene flow infinite population size and no selection (natural nor forced).You can see that some of these are kinda extreme and really hard to get, but with approximations, we can work.
For example, instead of an "infinite population size" we have enough with a really large population, such that genetic drift is negligible.
Concluding, yes, it is possible (but really difficult) for a population to not evolve for a while (at least, in nature), as long as the 5 assumptions above are met.

Which two structures engage to create a muscle contraction?.
Muscle contraction occurs when actin connects with myosin.
Muscle contraction occurs thanks to an action potential, which transmits a stimulus to the interior of the muscles.
For fiber tension to occur, the myosin head must bind with actin, slip, release, and then connect with another actin.This electrical signal allows the actin and myosin proteins to move, thereby generating contraction of the muscles.Therefore, we can conclude that myosin is a protein found in muscle fibers in order to bind to actin protein and cause muscle contraction.
