Answer:
1. Osmosis is the spontaneous net movement or diffusion of solvent molecules through a selectively permeable membrane from a region of high water potential to a region of low water potential, in the direction that tends to equalize the solute concentrations on the two sides.
2. Plants obtain water through their roots. Water present in the soil (or air, in the case of air plants) enters the plant through the epidermis of the root. The epidermis is a very thin single layer of cells. The water passes through the membranes of plant cells and also fills the spaces in between the cells.
3. This experiment allows you and your child to talk about the circulatory system and "capillary" action. The small "vessels" in the celery stalks carry the water and color to the leaves, like the way blood travels through your body.
4. A great way to introduce basic science concepts are through fun and visual experiments such as this Celery Experiment. It requires just a few items and is a fun way to teach children about how a plant absorbs water. This process is called Osmosis. We will learn about how plants absorb water using colored water and celery stalks.

How did the bombardment of Earth by solid particles affect its temperature
Answer:it affected it by being hot
Explanation:
snglekns
The bombardment of the earth by solid particles affects its temperature because the bombardments release heat and make the earth warmer, and due to this, the early earth was hotter.
What is the earth?The Earth is the planet in the solar system that moves around the sun, and it has living plants and animals along with non-living substances such as soil, air, water, etc. Most of the earth is covered with water and the earth has various populations, biomes, and biodiversities, and all of this biodiversity is due to changes in climate and geography, which result in the presence of various animals.
Hence, the bombardment of the earth by solid particles affects its temperature because the bombardments release heat and make the earth warmer, and due to this, the early earth was hotter.

this year there were 32 ants born in an ant hive. Due to the new pesticide that was used in the area, 32 died. With an overall population of 1000 ants in the hive, what is the change in population? Do you have a positive, negative, or zero change in population? How many members are in the new population?
Answer should contain the following information: work for calculating the change in population positive, negative, or zero change in population. Work for calculating the new population.
Answer:
0 change in population. I think.
Explanation:
first we are adding 32 ants to the total because 32 ants were born so 1000+32 = 1032.
Next we are subtracting 32 ants from the new total because a pesticinde was used in the area. So 1032 - 32 is 1000. 1000 was the original total so there was not a decrease in popualtion or an increase.

It takes energy for an organism to produce a particular structure such as a stripe on a clover leaf that is otherwise plain.
Why might cyanide-producing clover produce striped leaves?
Answer:
increases its ability to resist predation because the snails that eat it die
In general, two types of white clover can be found in a variety of habitats around the world. The first has plain green leaves, while the second produces cyanide as a defensive strategy against herbivores and signals its presence with white stripes on the leaves.
What are defensive behavior?Claws, teeth, disguising, poison, imitation, and adaptations such as echolocation are all common defense mechanisms. Some are uncommon but extremely effective.
A nonhuman animal's behavior to avoid of been hurt or killed by another.
This could include defensive aggression against a potential predator or a member of its own species, from its own group or from another group, or animal escape actions to avoid the source of harm.

The first has plain green leaves, whereas the second, as a defensive mechanism against plant eating organisms, produces cyanide and signals its presence with white stripes on the leaves.

5. Drug X blocks ATP regeneration from ADP and phosphate. How will muscle cells respond to this drug?
A. by absorbing ATP from the bloodstream
B. by using ADP as an energy source
C. by using glycogen as an energy source
D. none of the above
The muscle would contract with isotonic force. The muscle would contract isometrically. As a result of the actin-myosin cross bridges' inability to persist, the muscle would relax and lengthen. Thus, option D is correct.
What is effect of drug on ATP inhibition?Efrapeptins and aurovertins, two types of antibiotics, prevent ATP synthase from producing or breaking down ATP.
The rotor, the core cavity of the enzyme, and the particular -subunit catalytic site are where the efrapeptins bind to ATP synthase. This is because there won't be an ATP synthase-driven proton gradient.
The inability of the inner mitochondrial membrane to remain impermeable to protons or the cessation of electron transport will prevent oxidative phosphorylation from taking place.
Therefore, muscle contract with isotonic force.

How has vehicle fuel consumption in comparison to miles traveled changed since 1960? What is the likely cause for this change?
Answer:
After World War II, economic growth, population growth, rapid suburbanization, and the closing of some public transit systems led to more reliance on personal vehicles for transportation. The number of cars and trucks in the United States increased dramatically, as did the number of highways. One result of the rapid increase of motor vehicles was air pollution, especially in cities, that had serious impacts on public health and the environment.

Put the stages of the nitrogen cycle in their correct order.
Fixation or volatilization, mineralization, nitrification, immobilization, and denitrification.
The sequence is as follow: Fixation, Nitrification, Assimilation, Ammonification and Dentrification.
What is a nitrogen cycle?The nitrogen cycle is the process by which nitrogen is converted into different chemical forms and moves between the biosphere, atmosphere, and geosphere. The stages of the nitrogen cycle, in order, are:
Nitrogen fixation: Nitrogen gas in the atmosphere is converted into a usable form, such as ammonia or nitrite, by nitrogen-fixing bacteria.
Nitrification: Ammonia or nitrite is converted into nitrate by nitrifying bacteria.
Assimilation: Nitrate is taken up by plants and converted into organic nitrogen compounds, such as proteins and nucleic acids, through the process of assimilation.
Ammonification: Organic nitrogen compounds are broken down by decomposers, such as bacteria and fungi, into ammonia or amino acids.
Denitrification: Ammonia or nitrite is converted back into nitrogen gas by denitrifying bacteria, completing the cycle.
