Answer:
Plant-like protists produce almost one-half of the oxygen on the planet through photosynthesis. Other protists decompose and recycle nutrients that humans need to live. For example, medicines made from protists are used in treatment of high blood pressure, digestion problems, ulcers, and arthritis. Fungi are very important ecologically, because they are one of the most important decomposers in most ecosystems. They help to break down plant fibers such as dead leaves and wood and allow the nutrients to be released into the soil. Fungi are useful to humans because they have economic value.

If Plants no longer existed on earth then there would be no way for carbon dioxide to be converted into oxygen, without oxygen animals and humans alike would die. The Worlds "Air" would be toxic for us to breathe, we need plants to survive. Without plants, animals would die of starvation, and predators would as well without substance.
Which of these statements is correct about material 1 and 2?
The half-lives of Material 1 and Material 2 are same.
The half-life of Material 2 is one-fourth of the half-life of Material 1.
The half-life of Material 2 is 5 years more than the half-life of Material 1.
The half-life of Material 1 is 5 years more than the half-life of Material 2.
Answer:
D. The half-life of Material 1 is 5 years more than the half-life of Material 2.
Explanation:
As you can see in the graphs for material 1 to get to 50% it takes 30 years. for material 2 it takes 25 years to get to 50%. Therefor the halflife of material 1 is 5 years more than material 2
Labrador retrievers are traditionally black, brown, or yellow. The B allele codes for black fur, and the b allele codes for brown fur. The E allele allows the pigment to be deposited in the fur, while the e allele doesn't allow the pigment to be deposited. If one lab has the genotype bbee, and another lab has the genotype BbEe, what is the chance that an offspring will be brown
Answer:
25% of offspring will be brown
Explanation:
4 out of 16 of will be brown
to convert this to a percentage do:
4 ÷ 16 × 100 = 25
Punnett squares are in the image
Brown offspring are circled
AZT is a drug that is commonly used to fight HIV infection. The active component of AZT is a nitrogenous base that mimics thymine. Normal nucleotides CANNOT covalently bond to the thymine mimic. HIV's reverse transcriptase enzyme will use the thymine mimic instead of using thymine, whereas our DNA polymerase will not make this mistake. What is the most likely explanation for how AZT prevents HIV replication
AZT works by selectively inhibiting HIV's reverse transcriptase, the enzyme that the virus uses to make a DNA copy of its RNA. Reverse transcription is necessary for production of HIV's double-stranded DNA, which would be subsequently integrated into the genetic material of the infected cell to produce its proteins. All reverse transcriptase inhibitors are analogues of the naturally occurring deoxynucleotides needed to synthesize the viral DNA and they compete with the natural deoxynucleotides for incorporation into the growing viral DNA chain.
1. What happens to a plant that is put into a dark place? The plant's green color fades because it cannot perform photosynthesis without light. It grows taller.
Answer: The answer is the green part of the plant faces away because it cannot perform photosynthesis without light.
Explanation: The reason for this is because sunlight is always important to receive while performing photosynthesis because without sunlight, the plant would lose one of its major factors for photosynthesis.
What is the purpose of a control in this experiment?
Question 9 options:
The control is the tube that only has milk in it.
The control is the one tube that we know will show milk digestion.
The control is the one tube that we know will not show milk digestion.
The control is the only one the scientist changes.
Answer:
I can't definitively answer this because I don't know the experiment, but I can help.
Explanation:
The "control group" of an experiment is like a dry simulation, where there is no variables changed across all the different trials you do. This is different from a dependent variable or an independent variable. Using your newfound knowledge of what a control group is you can automatically cross off the last option.
Since I cannot see what your experiment was I can't give you which of the top 3 answers it is however. You need to look at which one has no change.
If I were to blindly guess I would say the top option seems like the most likely answer.

What characteristic could provide a species with a better chance of surviving a drastic environmental change?
(A) A small population size
(B) A highly diversified gene pool
(C) specialized cells within the body
(D) Many individuals with the recessive trait
A highly diversified gene pool could provide a species with a better chance of surviving a drastic environmental change. So, the correct option is B.
What is Diversified Gene pool?Greater genetic diversity within a population is made possible by a diverse gene pool, which raises the possibility that at least some members of the population will exhibit features that are more adapted to the new environment.
This variety can develop as a result of gene flow from other populations or mutations. The number of people having the recessive trait or a limited population size, however, would not always give an advantage in enduring environmental change. A species may have a better chance of surviving a severe environmental shift if its gene pool is extremely varied.
Therefore, the correct option is B.

Explanation:
Malaria, a type of parasite, infects 500 million people each year by infecting the red blood cells of its host. The virus, HIV, that causes AIDS, reports 50,000 newly infected persons. Which statement best differentiates the pathogens, parasites and viruses?
options: Although both rely on other living organisms to survive, viruses are usually beneficial.
Although both rely on other living organisms to survive, parasites feed on the host organism.
Although both are living organisms, viruses break down dead plants and animals that other organisms use.
Although both are living organisms, parasites depend on the cells of living things to reproduce.
Answer:
The second statement clearly differentiates the pathogens best. Parasites feed on living host while viruses depend on the cells of other organisms to survive and reproduce as they cannot function outside a living host.
Although both rely on other living organisms to survive, parasites feed on the host organism. The correct option is B.
What are parasites?A parasite is an organism that lives on or in the host and obtains its food from or at the expense of the host.
Protozoa, helminths, and ectoparasites are the three main types of parasites that can cause disease in humans.
They frequently go unnoticed because they have few symptoms. However, these infections frequently result in serious illnesses such as seizures, blindness, heart failure, and even death.
A parasitic relationship takes place when one lifeform, the parasite, feeds on another organism, the host, causing harm and possibly death.
The parasite lives on or in the host's body. Tapeworms, fleas, as well as barnacles are examples of parasites.
Thus, the correct option is B.

what are the chances that a color blind man will have a color blind grandson what are the genotypes for all involved.
Answer:
Depends
Explanation:
It depends if the genotypes are hetero.zygous or resessive/dominant homo.zygous. Being colorblind could be represented by a resessive genotype like, bb. if their son/daughter has Bb or bb or their son/daughter in law has a resessive trait then having a color blind grandchild maybe possible. The colorblind grandson has parents that both have at least 1 resessive trait, then the grandson could not be colorblind.

The first unstable compound formed during C3 cycle is:
(a) 3-carboxy,2-keto, 1,6 bi phosphorobitol
(c) 2-carboxy,3-keto,1,5 biphosphorobitol
(b) 2-carboxy,3-keto,1,5-biphosphorobitol
(d) 3-carboxy,3-keto, 1,6-biphosphorobitol
Answer:
(b) 2-carboxy,3-keto,1,5-biphosphorobitol
Explanation:
2-carboxy, 3-keto, 1,5-biphosphorobitol is the first unstable molecule formed during the C3 cycle. Due to its instability, this molecule is quickly broken down into two molecules each containing 3 carbon atoms, called 3-phosphoglyceric acid, this breakdown is done through water in a process known as hydrolysis.

a Shape
b Volume
c Arrangement of atoms, molecules
d All of the above
Answer:
d all of the above :)
Explanation:
hope this helped
Answer:
D) All of the above.
Explanation:
The Shape of a solid does not change (with exceptions), and the atoms typically remain static with little freedom of movement.
The volume of the solid also stays exactly the same if no external adjustments are made.
The arrangements of atoms & molecules are definitive and packed together, giving little movement, therefore allowing the solid to keep form.

1. Identify one population of organisms shown in the food web, other than rabbits or mice, that would likely be affected by the introduction of snowy owls AND explain why their population would be affected.
2. State which level, a, B, or C, contains the least total available energy. Support your answer.
Answer:
The population if snakes will decline because there will be competition between snakes and snow owls. The snow owls will eat the mice, but if there's only a small population of mice. Only a few snakes will eat, other snakes will die of starvation. There will be competition between snow owls, hawks and mountain lions, but they have other sources of food, unlike snakes.
Level C contains the least amount of energy. This is because each level gets less and less energy per meal, beacuse energy is released by each organism.
