Which is an example of positive gravitropism?a. the plant shoot growing up out of the soil
b. the plant flower opening with the sunrise
c. the plant root growing down into the soil
d. the plant turning towards the sun

Answers

Answer 1
Answer:

Answer:

c. the plant root growing down into the soil

Explanation:

The plant root going down deep into the soil is an example of positive gravitropism. Gravity pulls everything towards the center of earth i.e. downwards and roots follow the direction of gravity automatically by growing downward towards soil that is why it is known as positive gravitropism. In short we can say that root favors the direction of gravity.

Shoot on the other hand show negative geotropism/gravitropism i.e. it grows towards the opposite direction of gravity. Shoot grow towards upside direction i.e. away from the surface towards sky.

Omg please help ASAP Atmospheric nitrogen has to be combined with other elements, or fixed, in order to be used by plants. Lightning is one way that nitrogen is fixed. When lightning occurs, the extreme heat breaks the bonds in nitrogen molecules, allowing nitrogen to combine with oxygen and form nitrogen oxides. In what way is most of the nitrogen fixed by lightning made available for use by plants?aIt is moved by the wind toward dry areas.bIt is incorporated into the exoskeletons of flying insects that eat plants.cIt is inhaled and exhaled by birds roosting in trees during rainstorms.dIt is carried by rain to the soil.

Which statement best summarizes the water cycle?

Answers

Is there a list of statements you have to choose from?
If so, please tell us them. If not, you can summarize it by saying something like:

Water starts at a spring, heads to the sea then vaporizes and is pushed back to land where is condenses and rains, flows to the sea, and the cycle starts again.

Answer:

The water on earth changes forms as it moves from one reservoir to another.

Explanation:

The other two answer choices are

1: as water moves through an ecosystem, its energy is lost between trophic levels.

2:The water on earth changes forms as it moves from one reservoir to another.

and

3: Water in the atmosphere must be converted to another chemical before animals can use it

The correct answer of course would be answer choice 2. It does change forms as in states of matter from liquid to gas (water vapor) to solid (ice) and back again. This is the best summery of what the water cycle means.

1 is incorrect because it violates the law of conservation of energy. Water has nowhere to go so it stays on the surface of the earth.

And three is wrong because it simply does not describe the water cycle.

Two scientists do not agree on which type of grocery bag is better for the environment. What is the most likely outcome of their disagreement? A. Both types of grocery bags will be discontinuedB. More studies will take place on the issue
C. Some decrease in interest in the issue
D. No future consensus among other scientists

Answers

I think the correct answer from the choices listed above is option B. When two scientist do not agree on which type of grocery bag is better for the environment, most likely, more studies will take place on the issue. This is because scientists will not stop researching on things until they something that they believe is possible. Hope this answers the question.

The most likely outcome of their disagreement is more studies will take place on the issue.

What is Disagreement?

A disagreement is known to be when two or more people are not at a consensus and thus there will be controversy or conflict.

Since there are Two scientists who may not believe in the same thing in regards to another, the most likely outcome of their disagreement is more studies will take place on the issue.

The nerves that control voluntary responses like those connected to your muscles are part of the _____ nervous system. A.somatic
B.autonomic
C.sympathetic
D.parasympathetic

Answers

Answer:

The correct answer would be A. somatic nervous system.

A somatic nervous system is sub-set of the peripheral nervous system which controls the voluntary actions and body movements with the help of skeletal muscles.

This system mainly consists of two types of nerves:

Afferent nerves: Theses are sensory nerves which carry stimulus or information from receptors to the central nervous system (brain and spinal cord).

Efferent nerves: These are also termed as motor nerves which carry commands or responsive information from the central nervous system to the muscles.

The muscles contract and produce movements.
