Answer:
Explanation:
Coronavirus is mutating because as more people are getting the virus, that gives that virus a change to mutate and form a different strand. When a virus hijacks a person cells, it causes that cell to start producing the DNA of the virus, but because human cells where not made to produce the DNA of a virus, mistakes happen, thus slightly changing the DNA of the virus which can then cause a new strand of the virus to appear.
Define each of the stress types:
a. Stress
b. Compression
c. Tension
d. Shearing
Explanation:
STRESS : A state of mental or emotional strain or tension resulting from adverse or very demanding circumstances.
COMPRESSION : If a cylinder is compressed under the action of the applied force, the restoring force per unit area is known as the compressive stress.
TENSION : Mental or emotional strain. OR The state of being stretched tight.
SHEARING : A deformation of a material substance in which parallel internal surfaces slide past one another.

Which statement is NOT part of the kinetic theory?
all matter is made up of particles
particals collide with each other and their container
particals of matter are locked into permanent positions
Answer:
im almost 100% sure its the last one "particles of matter are locked into perm positions"

Are all resources distributed evenly throughout the world?
plss help fast
Answer:
Natural resources are not evenly distributed all over the world. Some places are more endowed than others — for instance, some regions have lots of water (and access to the ocean and seas). Others have lots of minerals and forestlands. Others have metallic rocks, wildlife, fossil fuels, and so on.
Explanation:
Discuss the similarities and differences between whale flippers and flukes and fish fins, using the scientific terms "homologous structures" and "analogous structures" in the discussion.
Answer:
The whale's flipper and tail flukes and fish fins are analogous structure as they have different structural formation but they perform the same function. Flipper and tails are locomotory organs in the whale and helps the whale in propelling similarly fins in the fish assist the fish in swimming.

Why do organisms with one color produce few offspring than those with multiple colors?
Answer:
atural selection can cause microevolution (change in allele frequencies), with fitness-increasing alleles becoming more common in the population.
Fitness is a measure of reproductive success (how many offspring an organism leaves in the next generation, relative to others in the group).
Natural selection can act on traits determined by alternative alleles of a single gene, or on polygenic traits (traits determined by many genes).
Natural selection on traits determined by multiple genes may take the form of stabilizing selection, directional selection, or disruptive selection.
Explanation:
This is science, but that is not an option to choose

Which of the following stages of complete metamorphosis involves a period of continuous
eating?
A. pupa
B. adult
C. egg
D. larva
Answer: I think it's A
Explanation: Butterflies, moths, beetles, flies and bees have complete metamorphosis. The young (called a larva instead of a nymph) is very different from the adults. It also usually eats different types of food. There are four stages in the metamorphosis of butterflies and moths: egg, larva, pupa, and adult.
Hope this helps :D

Most live underground to stay cool.
Explanation:
A large volcanic eruption can produce a cloud of ash that can impact the world's climate for some time. A cloud of ash that blocked out the sun for four months would MOST LIKELY have which of these effects?
A) higher temperatures on Earth and increased rates of photosynthesis
B) large amounts of precipitation and flooding of coastal areas
C) lower temperatures and slower rates of plant growth
D) high rates of extinction among reptiles and amphibians
Answer: C
Explanation: ash prevents sunlight from reaching the earths surface therefore lowering the temperature.

Answer: there you are.
1. Describe the flow of energy to killer whales.
2. If killer whales were removed from the ecosystem, how would it
impact the other organisms?
3. What would you expect to happen if the algae population
increased?
4. Describe how the fish population would change if the seal
population decreased.
The killer whales have a tremendous flow of energy as the whale eats and consume more protein and a nutrient-rich diet.
What is a killer whale?1. A killer whale is also called an Orca and a toothed whale. The whale is the largest member of the killer whale specie and has tremendous flow of energy due to they fed on small and large aquatic forms.
2. If the whale is removed from the ecosystem then the food chain will get disturbed and there will large growth of other species of fish will be in abundance.
3. If the algae increase the oxygen in the lakes and seas will be depleted and other species will be impacted as the fish popuaion may get reduced.
4. if there a change in seal popualtion then popualtion of fish will double itself and again distub the food web.

The test: To understand if the ACTN3 protein affects running ability, researchers conducted a test. They recruited a group of competitive runners and measured the level of ACTN3 protein molecules each runner had in their bodies. Then, they had the runners participate in a sprint (a short-distance run). During the test, the runners sprinted as fast as they could for 100 meters.
Evidence: Scientists found that the runners who sprinted the fastest had the highest amount of ACTN3 protein molecules in their bodies.
Do you think that this evidence shows that the ACTN3 protein determines running ability? Explain your ideas using the words protein, trait, and feature in your response.
Answer:
The ACTN3 gene encodes the alpha-actinin-3 protein which is present in fast-twitch muscle fibers. ... Although having one or two variant forms of the ACTN3 gene does not have any harmful effect, an individual's ACTN3 genotype does affect their athletic ability.

What are they most likely to observe about the stems after turning the jar on its side?
A: Grow sideways in their new position
B: Start growing downward in their new position
