The lab that tested the water initially determined that the water quality grew worse between 2005 and
2007. Based on your observations do you agree or disagree with their findings? Why?
Answer:
Most water systems test for lead as a regular part of
water monitoring. These tests give a system-wide
picture, but do not refl ect conditions at a specifi c
household faucet.
If you want to know if your home’s drinking water
contains unsafe levels of lead, have your water tested.
Testing is the only way to confi rm if lead is present or
absent.
Some faucet and pitcher fi lters can remove lead from
drinking water. If you use a fi lter to remove lead, be
sure you get one that is certifi ed to remove lead by NSF
International.

Which THREE statements describe how the models of mitosis and meiosis demonstrate genetic continuity?
Chromosomes are divided up evenly during Anaphase (Anaphase I of meiosis), ensuring that the daughter cells will have the correct number to reproduce.
In Interphase the chromosomes have duplicated, indicating that there will be enough genetic material to separate into daughter cells capable of reproduction.
In Prophase (Prophase I and II of meiosis) the spindles form, indicating that the chromosomes will be split evenly, and the daughter cells will receive the appropriate amount of genetic material.
In Metaphase (Metaphase II of meiosis) the chromosomes are lined up properly, indicating that the chromatids will separate evenly and provide the daughter cells with equal amounts of genetic material.
In Telophase (Telophase II of meiosis) the amount of chromatin present is equal to the amount present during Interphase, indicating that the daughter cells will receive the same amount of genetic material as the parent cell.
Answers: A,B,D
Explanation: :I took the test and got this question right .
The three statements that describes how the models of mitosis and meiosis demonstrate genetic continuity are listed and explain below.
In Anaphase, chromosomes line up in the middle of the cell while the spindle fibres pulls them apart.
Therefore the statement below about anaphase is correct.
Chromosomes are divided up evenly during Anaphase (Anaphase I of meiosis), ensuring that the daughter cells will have the correct number to reproduce.In interphase, the synthesis of DNA occurs where the chromosomes replicates forming two identical copies of DNA.
That is, the cell now has 92 chromosomes which is enough DNA for two cells.
Therefore the statement below about interphase is correct.
In Interphase the chromosomes have duplicated, indicating that there will be enough genetic material to separate into daughter cells capable of reproduction.In the prophase, the mitotic apparatus appears; this consists of two centrioles separated by the mitotic spindle which is formed from microtubules.
The formation of these mitotic spindle fibres indicates that the chromosomes will be split evenly.
Therefore the statement below about prophase is correct.
In Prophase (Prophase I and II of meiosis) the spindles form, indicating that the chromosomes will be split evenly, and the daughter cells will receive the appropriate amount of genetic material.Learn more here:

Explanation:
espero ter ajudado boa noite
A submicroscopic virulent agent that infects animals, plants, bacteria etc. is called viruses. They are capable of copying inside host cells only. Viruses cause many diseases in animals and plants.
The correct discussion is:
Student A believes that viruses are not living organisms.
The student's statement can be explained as:
The virus is not capable of reproducing on its own without a host system. Therefore they cannot fit in the definition of a living organism. They just have a genetic material encapsulated in protein coats and do have defined cell structures, unlike prokaryotes and eukaryotes.Therefore, viruses are not contemplated to be living.

To read signs, you need to have good ________ . focal vision peripheral vision paracentral vision double vision
To read signs, one needs good peripheral vision. The capacity to see things that are beyond of one's direct line of sight is known as peripheral vision. It is the capacity to perceive things that are beyond of one's direct field of vision.
Because it enables a person to perceive items that are situated at the boundaries of their peripheral vision, this form of vision is crucial for reading signs.
For instance, it's crucial to be able to understand signs that are placed along the side of the road when driving. A person might not be able to see the signs and might miss crucial information without adequate peripheral vision. Aside from peripheral vision, clear focus vision is crucial for reading.

explain the correlation between solar radiation and kelp biomass.
Given what we know, we can confirm that although sunlight is beneficial to plant growth, intense solar radiation has been proven to be detrimental to the survival of kelp, thus reducing its biomass.
How does solar radiation affect kelp?Solar radiation is not harmful in very low amounts.
However, when exposed at long intervals or high intensity, it has been shown to cause tissue damage.
This tissue damage will inhibit the kelp's ability to undergo photosynthesis.
This means it will not be able to grow, and its biomass will be reduced.
Therefore, given the effect of solar radiation in damaging the kelp's ability to photosynthesize and thus reducing its growth, we can confirm that intense or prolonged exposure to solar radiation reduces kelp biomass.

Explain why carbon dioxide is constantly given off during the Krebs cycle.
Answer:
Hope it helps
Explanation:
mark me brainliest and follow me for more answers
Glycolysis and the citric acid cycle both produce carbon dioxide, which is a crucial byproduct (Krebs cycle). This oxidized carbon is a metabolic waste product that must finally be eliminated through transit to the lungs and subsequent exhalation into the environment.
What is the purpose of Krebs cycle?
Pyruvate is converted into three different products by the Krebs cycle: carbon dioxide, a little quantity of ATP, and the reduced molecules NADH and FADH.
Each acetyl group adds two carbon atoms to the citric acid cycle. On each cycle turn, two carbon dioxide molecules are emitted.
However, these do not include the identical carbon atoms that the acetyl group contributed on that turn of the circuit.
Therefore, carbon dioxide is constantly given off during the Krebs cycle.

A mouse population that is originally white in color becoming darker in color after several generations is an example of natural selection.
What do you mean by natural selection?Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations.
Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways.
