Answer:

One key way by which species evolve over time in response to changes in environmental conditions is adaptation by natural selection acting over generations. Characteristics that aid in effective survival and reproduction in the new environment grow more prevalent, while those that do not become less prevalent.

what law out of newtons law is this statement ? please help

( The phone will hit the ground and the ground will push up with the same force. With a case, it is increasing the amount of time the phone hits the ground. This means the reaction force will be less.)

Answers

Answer:

Newton's Third Law

Explanation:

Newton's Third Law is: If object A exerts a force on object B, then object B must exert a force of equal magnitude and opposite direction back on object A.  

In this case, Object A is the Phone, and Object B is the ground. When the phone(Object A) hits the ground(Object B), the ground pushes up on the phone making the time increase and makes the reaction force less. Hope this helps!

Explain how building the lake near Galetown could affect the amount of water vapor and the amount of rain.​

Adding a lake near any town will most likely increase rainfall because of the added water, and water vapor levels will also increase. Because of the excess water in the environment, more water will be found in the surrounding atmosphere (the same reason precipitation will increase in the area.)

Explain the difference: a myelinated axon conducts impulses faster than non-myelinated axon of the same diameter

Answers

Answer:

A myelinated axon conducts impulses faster than a non-myelinated axon. ... Therefore, in myelinated neurones, the nerve impulse is said to jump from node - to - node, a impulse pathway known as Saltatory Conduction.

__________________________________

D. Errors During DNA Replication

[tex]\color{Violet}\rm{☘︎Hopeithelps!}[/tex]

Mutations arise spontaneously at low frequency owing to the chemical instability of purine and pyrimidine bases and to errors during DNA replication. Natural exposure of an organism to certain environmental factors, such as ultraviolet light and chemical carcinogens (e.g., aflatoxin B1), also can cause mutations.

Explain how the investigation could indicate that chlorophyll is needed for photosynthesis. Include the role of chlorophyll in your explanation.

Answers

Chlorophyll is the green pigment found in the chloroplasts of leaves. It gives leaves their green colour and aids in the process of photosynthesis by trapping light needed for it.
The variegated leaf experiment is used to investigate that chlorophyll is needed for photosynthesis:
- Take a variegated leaf
- Take another leaf and don’t do anything to it (it’s going to act as a control plant)
- Place the leaves in different Petri dishes containing moist cotton wool
- Leave the Petri dishes in the sun for about 6 hours
- Carry out the iodine test for starch on both leaves by placing 2-3 drops of iodine solution on both leaves
- You’ll find that the control turns dark blue/black while the variegated leaf is stained yellow on the white parts but dark blue/black on the green parts.
The blue/black color shows that starch is present in the leaf meaning photosynthesis took place. The yellow color is just the color of iodine solution.
The white parts do not contain starch because there is no chlorophyll to trap sunlight needed in the process of photosynthesis. This shows that chlorophyll is necessary in the process of photosynthesis.

As native mason bees visit flowers, they spread pollen while also consuming nectar from the plant. This is an example of symbiosis.
true or fasle

Answers

Answer:

True

Explanation:

Symbiosis is a type of relationship or interaction between two different biological organisms/species by which both are benefited. The bees such as mason bees are pollinators. Pollinators are animals (especially insects) that help the development of seeds and the fruit surrounding seeds by the pollination of flowers, i.e., by the transference of pollen from male anthers of a flower to the female stigma. During this process, pollinators eat nectar, which is a sweet energy-rich liquid secreted by flowers. In consequence, both species (i.e., plants and mason bees) are benefited from this interaction.

In the early days of life on Earth, plants were exposed to extremely high doses of ultraviolet radiation, Constant UV exposure
resulted in some land plants developing narrow leaves with thick, waxy cuticles. Over many, many generations, these narrow

Relate the development of plant needles to the occurrence of mutations,
A)
Plant needles adaptations for survival that some plants developed due to
high temperatures on Earth
B)
Plant needles are the result of leaf cell mutations that made some leaves
thick and waxy, while other leaves did not change,
Plant needles are the result of neutral mutations to leaf tissue that would

Our atmosphere acts like a blanket trapping heat and keeping Earth at a habitable temperature, it’s this retaining of heat that is referred to as the Greenhouse Effect. The greenhouse effect is caused by greenhouse gases that trap heat from the sun, the more greenhouse gases there are the more heat is retained

HOW IT WORKS
The heat from the sun (solar radiation) has a very short wavelength and this can pass easily through the layer of greenhouse gases. This wavelength is called Ultraviolet radiation. As the UV rays strike the Earth, the Earth redirects the rays back into the atmosphere. We feel this as heat. The heat from the earth (terrestrial radiation) has a longer wavelength (infrared) some of this becomes trapped by the layer of greenhouse gases.

GREENHOUSE GASES
Water vapor (H20) is the most prevalent greenhouse gas and occurs naturally. Some greenhouse gases are both natural and man-made including carbon dioxide (CO2) & methane (CH4).

Describe the size of insolation when it strikes the Earth.

What would happen if there were no greenhouse gases to trap heat?
