Answer:
B.
Explanation:
I picked it and it said B was the right answer.
Water is taken up by roots from the soil and moved as a liquid by xylem to the leaves. Small holes in the leaves allow CO2 to enter the leaf for photosynthesis and water to escape as a vapor. Thus option B is correct.
What is movement of water during photosynthesis?Water moves through a plant during transpiration, where it evaporates from aerial parts like leaves, stems, and flowers.
Plants absorb water (H2O) and carbon dioxide (CO2) from the soil and atmosphere during photosynthesis.
Water molecules pass through a membrane during osmosis from an area of higher concentration to a region of lower concentration.
Water is taken up by the plant's roots and transported up its circulatory system via xylem tissue.
As water enters the leaf and is absorbed by osmosis into the cells that create glucose and oxygen when combined with CO2. The vacuole inside the cell can store water.
Therefore, Transpiration pull model best shows the movement of water during photosynthesis.

Which of the following is NOT true of carbon?
A. It is present in all organic compounds.
B. It is a relatively small atom.
C. It will do anything to fill up its electron shell.
D. It can bond with multiple other atoms at once.
Anybody know?
Answer:
it is b
Explanation:
The characteristic which is not true of carbon is: B. It is a relatively small atom.
Carbon can be defined as a non-metallic and tetravalent chemical element represented with the chemical symbol C and it has an atomic number (number of protons) of six (6). This ultimately implies that, carbon is found in Group 6 of the periodic table because of its six (6) valence electrons, that are found in the outermost shell of its atomic nucleus.
Some of the characteristics of carbon include the following:
It has the ability to form a covalent bond with multiple other atoms at once.It is found in all organic compounds.It does anything to fill up its electron shell.It is a relatively large atom, which allows it bond with multiple other atoms.Read more carbon on here: https://brainly.com/question/19954749
How does the mean speed of the water molecules change as they are heated
The average speed of water molecules increases as they are heated, it is due to kinetic energy.
How does water molecule changes due to heating?When change in temperature, there is also a change in the kinetic energy of the molecule. If an increase in temperature, the kinetic energy also increases. Thus, the movement of water molecules increases as we heat it up.
If molecules are heated up, it changes the kinetic energy and increases the collision and diffusion rate of the molecule.
When any substance gets heated it gains thermal energy and if cooled it losses thermal energy. If a molecule gets kinetic energy or a water potential is higher than the concentration of water in a system.
Therefore, the mean speed of the water molecules increases as they are heated.

Explain how traits are passed down in an organism, such as a dog.
Answer:
Heredity, also called inheritance or biological inheritance, is the passing on of traits from parents to their offspring; either through asexual reproduction or sexual reproduction, the offspring cells or organisms acquire the genetic information of their parents.

A blue whale swims in the ocean. Which of Earth spheres are represented in this scenario?
O hydrosphere and biosphere
O atmosphere and lithosphere
O lithosphere and hydrosphere
O atmosphere and biosphere
Answer:
I believe the correct option is ''O hydrosphere and biosphere''
Explanation:
''A blue whale swims in the ocean.''
breaking up the sentence, ''A blue whale''. That is apart of the Biosphere as it includes all living orginisms, including said blue whale.
''Swims In the Ocean'', the Ocean is made up of the earths water, which sudgests the Hyrosphere as it is all waters on the earth's surface.

What happens to the amount of light as the moon travels from the new moon phase to the full moon phase?
Explanation:
Between the new and full Moon, the amount of Moon we see grows — or waxes from its right side toward its left side. As it passes the full Moon stage, the amount of illumination decreases — or wanes — from right to left. ... No matter where on Earth an observer is, however, the phases of the Moon occur at the same time.
[tex]\huge\bold\pink{Answer:-}[/tex]
Moon phases represent the names given to points in its orbit around Earth. Each phase lasts for only an instant as the moon constantly moves. To the naked eye, the full moon lasts about three days, but in reality, it is a full moon for just an instant before it begins to wane. The moon takes just under one month -- an average of 29 1/2 days -- to complete its phases.
Phases of the Moon:-The moon has eight phases: new moon, waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, last quarter and waning crescent. But it is not as simple as dividing 29 1/2 by eight to find out how long each phase lasts. The fraction by which the moon is illuminated steadily increases or decreases at all times.
