Answer:
C
Explanation:
There would be a high amount of nitrates and phosphates, which reduces the amoubt of oxygeb in the tank, that will lead to the difficulty of supportibg the excessive amount of aquatic plants.
Answer:
C. There is not enough oxygen in the
atmosphere to support excessive numbers of
aquatic plants.
Explanation:
n excess amounts, both nutrients can cause an increase in aquatic plant growth and algae blooms, called eutrophication. These algae blooms live at the water surface, in order to easily access oxygen and sunlight. As a result, eutrophication prevents lower water levels from access to sunlight and oxygen in the air.

The spleen and the thymus work together to fight infection. These organs together make up which next level of organization?
Answer:
Tissue
Explanation:
The spleen and the thymus work together to fight infection. These organs together make up immune system.
What is immune system?The immune system defends the organism's body against external invaders. Toxins and germs such as bacteria, viruses, and fungi are examples of these (chemicals made by microbes).
The immune system is made up of various organs, cells, and proteins that collaborate.
The thymus and bone marrow, lymph nodes and vessels, spleen, and skin are all vital to the immune system's proper functioning.
The spleen filters and stores blood, as well as producing white blood cells to fight infection or disease.
The thymus gland is located in the upper chest, beneath the breast bone. It is responsible for the maturation of a specific type of white blood cell that fights off foreign organisms.
Thus, immune system encompasses spleen and thymus.

In what order do the electrons move through the electron transport chain?
Answer:
Four Stages: Glycolysis (a transition reaction that forms acetyl coenzyme) A, the citric acid (Krebs) cycle electron transport chain, and chemiosmosis.
Explanation:
The flow of electrons through the components of the electron transport chain occurs in order of increasing reduction potential.
Electronic transport chain is the set of enzymatic complexes embedded in the mitochondrial membrane that oxidize NADH and FADH2, generating a proton gradient.
It basically comprises 2 processes:.
1) Electrons are transported across the membrane, from one carrier protein complex to another.
2) Protons are translocated through the membrane, which means that they are passed from the interior or mitochondrial matrix to the intermembrane space causing a proton gradient.
Oxygen is the final acceptor of the electron, combining with them and the H ion to produce water.
This chain comprises numerous associated components in the form of enzyme complexes, each of which has transmembrane proteins that support the complex on the inner mitochondrial membrane, an Fe-S flavoprotein, ubiquinone, and the cytochrome chain.
The electrons start out in order with very high energy, which they lose as they pass through the chain. In other words, the carrier molecules are reduced and oxidized, lowering electrons from high energy levels to lower ones.
Therefore, we can conclude that the flow of electrons through the components of the electron transport chain is carried out in order from high energy levels to lower ones.

You have an Elodea sprig in a test tube containing bromothymol blue. Then you watch it for several days. At what time of day will the oxygen level in the tube be the lowest?
a)just before sunset
b)midnight
c)just before sunrise
d)mid-afternoon
Answer:
c
Explanation:
If you put an Elodea plant in a test tube containing bromothymol blue and watch the oxygen level, the time of the day in which the oxygen level in the tube would be lowest will be just before sunrise.
First, there is a need to understand oxygen is produced as a result of photosynthesis according to the following equation:
[tex]6CO_2 + 6H_2O ---> C_6H_1_2O_6 + 6O_2[/tex]
The process of photosynthesis takes place in 2 reactions:
Light-dependentLight-independentOxygen is produced from the splitting of water in the light-dependent reaction. Hence, the production of oxygen stops when there is no light - when the sun sets.
Whatever quantity of oxygen that has been produced just before the sun sets would remain and will gradually be used for respiration by the Elodea plant until the sun rises again the following day.
Thus, the level of oxygen in the tube would usually be lowest just before the sun rises and oxygen can be produced again.

The body works to maintain homeostasis in response to what conditions?
Answer:The tendency to maintain a stable, relatively constant
Explanation:
The tendency to maintain a stable, relatively constant internal environment is called homeostasis. The body maintains homeostasis for many factors in addition to temperature. For instance, the concentration of various ions in your blood must be kept steady, along with pH and the concentration of glucose.
What human body response help maintain homeostasis?
Answer:
The endocrine system plays an important role in homeostasis because hormones regulate the activity of body cells. The release of hormones into the blood is controlled by a stimulus. For example, the stimulus either causes an increase or a decrease in the amount of hormone secreted.
Explanation:
Answer:
If a raise in body temperature (stimulus) is detected (receptor), a signal will cause the brain to maintain homeostasis (response). Once the body temperature returns to normal, negative feedback will cause the response to end. This sequence of stimulus-receptor-signal-response is used throughout the body to maintain homeostasis.

Describe how skin pigmentation is determined, and also
how it is affected by exposure to the sun.
Answer:
pigmentation is determined by the amount of melanin in the skin. Without melanin, the skin would be pale white with shades of pink caused by blood flow through the skin. The extra melanin makes your skin look darker or sun-tanned. In some cases, the sun causes an uneven increase in melanin production, which produces irregular coloring of the skin. The sun can also cause a permanent stretching of small blood vessels, giving your skin a mottled, reddish appearance.
Explanation:
A yellow cat is crossed with a black cat. You know that the black and yellow fur color traits are carried on the X chromosome and only one X chromosome is expressed in a cell. You observe that half the offspring are calico (patches of black and yellow) and half are black. Your friend Tien tells you that the black cat was the mother, the yellow cat was the father, and all the calico kittens are females. Is he correct? Write out all the possible crosses to test his answer.
Answer:
Tien is correct with his answer that all the calico kittens are females.
The reason and the possible crosses to test the answer are given below
Explanation:
First of all, the coat color in cats is hugely decided by the sex-linked X chromosome in the female. This X chromosome found in cats makes cats exhibit codominant traits. The calico cat is a blend of black and yellow patches. To be considered calico, a cat must carry an allele for the black color and an allele for the yellow color.
The male is no heterozygotes and since the Y- chromosome in the male doesn't affect the result of the coat color in the offspring, there has to be a rare genetic disorder that will result in a calico kitten that is male.
The possible crosses to test his answer:
Cross 1:
If the black cat was the mother her genotype would be: Xb Xb
If the yellow cat was the father his genotype would be: Xy Y
The possible offspring from the cross would result in:
XbXy XbY XbY XbXy ( where XbXy are calico females and XbY are black males)
Cross 2:
If the yellow cat was the mother her genotype would be: Xy Xy
If the black cat was the father his genotype would be: Xb Y
The possible offspring from the cross would result in:
XyXb XyY XyXb XyY (where XbXy are calico females and XyY are the yellow males)
