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.

Which electromagnetic waves have the highest frequency (use pictures above)
Which color in the visible light waves has the highest wavelength? Which has the lowest?
Which electromagnetic wave is the most dangerous (most energy)?
What is the relationship between wavelength and frequency?
What is the relationship between frequency and energy?
(any troll answers will be reported)
Gamma rays have the highest frequency (waves are close together/short wavelength)
Highest wavelength is red (distance between peaks is longest), lowest wavelength is violet (distance between peaks is shortest)
Gamma rays have the most energy (highest frequency) and are the most dangerous
Wavelength and frequency have an inverse relationship. As wavelength increases, frequency decreases and visa versa.
Frequency and energy have a direct relationship. As frequency increases, energy increases.
Answer:
See below.
Explanation:
● Gamma rays have the highest frequency.
○ The highest wavelength will be for red while the lowest wavelength will be for violet.
● Gamma rays are more dangerous & also have more energy.
○ Wavelength & frequency have an indirecly proportional relationship.
● Frequency & energy have a directly proportional relationship.

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.

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.

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.

This image shows the relative frequency of banded and non-banded snails in a population. If the frequency of banded snails decreased to 60% and non-banded snails increased to 40%, would you consider the population to be evolving?
Answer:
The nonbanded are evolving and the banded are not. It looks like something is either eating the banded shrimp and not the unbranded. Or the unbranded shrimp are eating the banded shrimp.

As per the image of the single-gene trait the phenotypes are shown as per those with and without bands. The phenotypes without band are 20% and that of with band is 80%.
If the population of the snails gets reduced by 60% and non-banded gets 40% then the population that evolves would be that of the nonbranded snails will increase.Learn more about the relative frequency of banded.

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.

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.

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.
