Answer:
A. The model illustrates active transport because energy is required for solute particles to cross the cell membrane.
Explanation:
Active transport is the transport of molecules from a region of lower concentration to a region of higher concentration. In other words, movement occurs against a concentration gradient.
Due to this, it requires energy in form of ATP for this movement to occur. Hence, based on this question, the model illustrates active transport because energy is required for solute particles to cross the cell membrane.

Genetic Variation
Explanation:
Mutations, gene flow, and sexual reproduction causes genetic variation. Mutatio is the changes in the sequence of genes in the DNA. Gene flow is the movement of genes from one organism to another, and sexual reproduction, is where new combinations of genes are created.
why is water molecule called polar
Answer:
Since oxygen has a higher electronegativity than hydrogen, the electrons of the molecule tend to group closer to the oxygen than to the hydrogen atoms. as well as , water is said to be a "polar" molecule, which means that there is an uneven distribution of electron density.

Answer:
gametes should be the answer.
Explanation:
Answer:
gametes (GAH-meetz), are involved. The male gamete, or sperm, and the female gamete, the egg or ovum, meet in the female's reproductive system. When sperm fertilizes (meets) an egg, this fertilized egg is called a zygote (ZYE-goat).
Explanation:
How are meiosis and mitosis different?
Answer:
Function. Mitosis is for the growth, development, repair of damaged cells and replacement of damaged cells in multi-cellular organisms. Meiosis is the production of gametes for sexual reproduction.
Location it takes place in. Mitosis takes place in all somatic cells! Meiosis takes place in the testes and ovaries. (In humans)
Number of daughter cells produced by a single parent cell. Mitosis produces 2 daughter cells from 1 parent cell. Meiosis produces 4 daughter cells from 1 parent cell.
Number of chromosomes each daughter cell contains. In mitosis, each daughter cell contains a diploid number of chromosomes. (2n) In meiosis, each daughter cell contains a haploid number of chromosomes. (n)
Presence of crossing over stage in Prophase. In mitosis, there is no crossing over (homologous recombination) that occurs in Prophase. In meiosis, there is crossing over (homologous recombination) that occurs in Prophase.
Genetically identical to parent cells? In mitosis, daughter cells are clones of their parent cell. Hence they are genetically identical to each other. In meiosis, daughter cells are genetically different to their parent cells as they contain different genetic codes due to crossing over that had led to the recombination of genes between homologues during Prophase I.
Genetically identical to daughter cells? In mitosis, daughter cells are clones of each other. Hence they are genetically identical to each other.

Explain A wood frog species in Alaska can survive being frozen
almost completely solid. In spring it thaws and becomes more
active. Wood frogs that live in warmer climates do not have this
trait. Explain how this trait relates to adaptation and speciation.
Wood frogs are found in the United States throughout the forests of Alabama and Northwest into Idaho. Wood frogs are the only frogs that live North of the Arctic Circle. Adults usually live in woodlands and lay in vernal pools.
Wood frogs live in a variety of habits, from forests to bogs to tundra. They hibernate on land and breed in water.
The Wooded frog does adapt in warmer climates by hibernating by nestling down into the leafy litter on the forest floor.

While dry cleaners are small businesses, they generate relatively large volumes of hazardous substances. EPA estimates the average dry cleaner generates 660 gallons of hazardous wastes a year. Unlike petroleum contamination which may break down over time by naturally - occurring bacteria in the environment, the chlorinated solvents that are used by dry cleaners are resistant to biodegradation. As a result, groundwater contamination from dry cleaners has a greater potential to migrate off-site which can be problematic since dry cleaners are often located within proximity to residential neighborhoods. Indeed, a 2002 Florida study found that dry cleaner contamination had migrated off-site at 57 percent of the contaminated sites. Due to these types of environmental hazards when commercial land is sold require a Phase 1 Environmental Assessment according to the Comprehensive Environmental Response, Compensation and Liability Act.
Why would the type of monitoring required as part Phase 1 Environmental Assessments be important if a dry cleaner was being sold?
Group of answer choices
This type of monitoring will allow the government to only sell land to businesses that have environmentally friendly practices.
The monitoring will allow the government to determine which type of business is better for the environment so dangerous businesses can be closed.
The monitoring will indicate any environmental damage done that should be remediated prior to selling the land.
The monitoring prevents the land from being resold to any dry cleaning businesses which can be damaging to the environment.
Answer:
This type of monitoring will allow the government to only sell land to businesses that have environmentally friendly practices.
Explanation:
This type of monitoring will allow the government to know about the businesses that causes pollution in the environment and the government is responsible to sell the land to those businesses that have used the methods which is environmentally friendly. The environmental friendly practices reduces the damage occur to the environment from human activities so the government must do monitoring of businesses.

what is the fluid excreted by kidneys for emotions?
Answer:
The kidneys remove from the blood the nitrogenous wastes such as urea, as well as salts and excess water, and excrete them in the form of urine. This is done with the help of millions of nephrons present in the kidney. The filtrated blood is carried away from the kidneys by the renal vein (or kidney vein).
Answer:
The fluid is called Urea
Explanation:
The kidneys remove from the blood the nitrogenous wastes such as urea, as well as salts and excess water, and excrete them in the form of urine.
2. animals eat plants and produce carbon dioxide and water how do you animals affect the amount of carbon in the earths atmosphere
Animals eat plants and produce Carbon-di-oxide. Due to this, the concentration of carbon increases in the Earth's atmosphere by the carbon cycle.
What is the carbon cycle?The carbon cycle is a biogeochemical cycle in which the exchange of carbon between the environment and the organisms occurs.
Plants are producers, they absorb carbon-di-oxide from the environment, and by the process of photosynthesis, they convert it into an organic molecule (glucose). When these plants are consumed by consumers, carbons enter the food chain. It transfers from primary consumers to secondary consumers and then tertiary consumers.
When the consumer respires, carbon is released into the environment in the form of carbon-di-oxide. When these animals die, their bodies decompose and carbon is absorbed again into the atmosphere.
Thus, this is how animals affect the amount of carbon in the atmosphere.
