Why is it important for organisms to get rid of waste?
There are different types of waste such as carbon dioxide and that must be removed. If they are allowed to accumulate they can and will cause poisoning which slows down vital chemical reactions. When excretory organs such as your kidney's are damaged, the organism quickly displays symptoms of poisoning and death is rapid unless treated immediately.

Which part(s) of your eye change light to electrical impulses?
Answer:
Light passes through the front of the eye (cornea) to the lens. The cornea and the lens help to focus the light rays onto the back of the eye (retina). The cells in the retina absorb and convert the light to electrochemical impulses which are transferred along the optic nerve and then to the brain.
Explanation:
A test cross to determine the genotype of a green-colored seed would best be represented by _______.
a. Yy x Yy
b. YY x YY
c. YY x Yy
d. Yy x yy
Answer:
d. Yy x yy
Explanation:
In Mendelian inheritance, a TEST CROSS is a cross used to determine the actual genotype of a dominant phenotype. The test cross is usually performed between the unknown genotype and a recessive genotype. If all the offsprings are dominant, the unknown genotype is the same allele but if the offsprings are half dominant and half recessive, the unknown genotype is HETEROZYGOUS.
In this case, a test cross to determine the genotype of a green-colored seed would best be represented by Yy × yy because a test cross must include a recessive genotype, which is "yy" in this case.

Since oxygen gas is being released, it can be inferred
that the plant is
A. producing glucose
B. releasing energy from water

Answer:
A. producing glucose
Explanation:
Since oxygen gas is being released, it can be inferred that the plant is producing glucose. Thus, the correct option for this question is A.
What are the products of the photosynthesis reaction?The products of the photosynthesis reaction are oxygen and glucose. They are produced when carbon dioxide and water react with each other in the presence of bright sunlight.
According to the context of this question, if a small water plant was placed in bright sunlight for five hours. Bubbles of oxygen gas were observed being released from the plant. This means that the plant started the process known as photosynthesis which assists the plant in delivering energy in the form of glucose.
Therefore, since oxygen gas is being released, it can be inferred that the plant is producing glucose. Thus, the correct option for this question is A.

Answer:
The correct option is A and C.
Quantitative and continuous
Explanation:
It is quantitative and continuous because A quantitative data is a data that it's value can be represented with numerical values or numbers or they are data that can be counted in numbers.
Continuous data is a quantitative data that can be divided into several parts and can take different values. It can be measured and represented in numbers.

Please help and please do not copy and paste from google and please use your own word ->Density is
Answer: Density is a measure of mass per unit of volume
Explanation:
The average density of an object equals its total mass divided by its total volume. An object made from a comparatively dense material (such as iron) will have less volume than an object of equal mass made from some less dense substance (such as water).
Explanation:Density is like a some measore of mass for unit now the average of some object equal like a mass divided by a total volume. now i know that ab object made from a dense material it could be the iron if that material is make it of iron it will going to have less volume than other object made from another less dense subtance (it could be the water)

What is carrying capacity and WHY is it
important for us to know about? Is it good or bad to be over capacity and
why
Answer:
Carrying capacity shows how much you can carry, over being more than what you can carry and under being less than you can carry. It is bad to be over capacity because you would be carrying more than you are physically able to.

What evidence does not back the claim that a chloroplast is an ancient bacterial photosynthesizing endosymbiont?
A. Chloroplasts can be affected by antibiotics, a class of drugs that target bacteria.
B.Chloroplasts have flagella and cilia and these structures are similar in shape and function to flagella and cilia found in bacteria.
C.Chloroplasts have their own genome, and the structure of their DNA is identical to that of bacterial DNA.
D.Chloroplasts replicate and divide through fission, the way bacteria divide.
Answer:
B. Chloroplasts have flagella and cilia and these structures are similar in shape and function to flagella and cilia found in bacteria.
Explanation:
The ENDOSYMBIOTIC THEORY is a theory that suggests the evolution of eukaryotic cells from prokaryotes. The theory explains that some organelles such as MITOCHONDRIA and CHLOROPLAST found in eukaryotic cells were once free-living prokaryotes. This theory was based on certain evidences that backed up the claim that chloroplasts were endosymbiont i.e a cell that lived in another cell. The evidences include:
- Chloroplasts have their own genome whose circular structure of DNA is identical to that of bacterial DNA.
- Chloroplasts replicate and divide through fission, the way bacteria divide
- Chloroplasts can be affected by antibiotics, a class of drugs that target bacteria.
However, among these evidences, the possession of flagella or cilia by chloroplasts is not included.
Scientific models can be made of plastic or even just be a drawing. Which is a limitation of the drawing and not a model? I need the answer quickly helppp
Answer:
It did not explain the process more clearly.
Explanation:
Limitation of the drawing is that it did not explain the process or phenomena clearly as compared to model which shows a phenomena more clearly. the main reason for that the model has a physical body while on the other hand, drawing is only the picture. in the model we can perform the whole process how a phenomena occurs, its different stages and its final outcome while these things can't be done with drawings.

All genes are made of DNA genes code for proteins proteins carry out life functions
O All genes are made of proteins, proteins code for DNA DNA carries out life functions
As
Answer:
Genes are made of DNA; DNA codes for proteins; proteins carry out life functions
Explanation:
The correct statement is "All DNA is made of genes: DNA codes for proteins: proteins carry out life functions"
The deoxyribonucleic acid (DNA) chain is known as a gene, a structure that is constituted as a functional unit in charge of the transfer of hereditary traits.DNA is the biopolymer that houses the data for the synthesis of proteins and that makes up the genetic material that cells have.The functions of proteins are specific to each of them and allow cells to maintain their integrity, defend themselves from external agents, repair damage, control and regulate functions, among other life functions.Therefore, we can conclude that DNA stores the instructions for the synthesis of all the proteins that make up an organism and the minimum units of this genetic information are called genes.

What would happen to a bunch of balloons that were inflated outside when it was 95 degrees F and you took them into an ice hockey rink where it was 45 degrees F *
Answer:
The balloon shrinks
Explanation:
According to Charles law, temperature and volume are directly proportional. When temperature increases, volume of the gas inside the balloon increases and vice versa at constant pressure.
However, when the balloons are taken into an ice hockey rink and their temperatures drop from 95 degrees Fahrenheit to 45 degrees Fahrenheit, the molecules of gas in the balloons loose energy and move at slower speeds tending to stick closer together. The volume of the balloon therefore decreases accordingly. This means that the balloon shrinks.
