2. How do plankton move through the water?
Answer:
It depends.
Explanation:
Some types of plankton float through the water.
While some types have a whip-like tail (flagella) to move through the water.
Answer:
Most plankton are very buoyant and float closer to the surface of the ocean rather than the bottom, but the current also greatly helps the plankton move from place to place

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.

When do you think the world's population will stop growing? Answer in a paragraph please (:
Answer:
Please read below
Explanation:
The worlds population won't stop growing till something bad in the wrold happens like a war or the fertility rates drop to an all time low.For example if a lot of people are out at a war the frertility rates are going to be low and the death rates will be high.Therefore the population will stop growing and will decrease or stay the same.

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.

Which of the following is not a cycle of matter?
O Nitrogen Cycle
O Energy Cycle
O Water Cycle
O Carbon Cycle
Nutrient cycle is also known as the cycle of matter. Nitrogen, water and carbon all three are cycle of matter but energy cycle is not. Thus, correct option is B.
What is Nutrient Cycle?
Cycle of matter are also known as Biogeochemical cycles. These cycle include both biotic and abiotic factors. Cycle of matter are described into five types based on matter: a. water cycle, b. nitrogen cycle, c. phosphorus cycle, d. sulfur cycle, e. carbon cycle.
Matter constantly moves in the cycle involving change in the state. The matter cycles are essential as they recycle important nutrients required for the survival of living organisms.
In contrast to this, energy flows in the atmosphere. It is the interaction between the energy sources within Earth. The interaction between energy sources and Earth's atmosphere is very significant and a small change could lead to significant change in climate behavior of an area.
Therefore, the correct option is B. Energy cycle is not a cycle of matter.

Which statement is FALSE? First exclude the four that are correct. While performing photosynthesis during the day, the chloroplasts of a green leaf produce Which statement is FALSE? First exclude the four that are correct. While performing photosynthesis during the day, the chloroplasts of a green leaf produce ATP to be used in the Calvin cycle. ATP as an energy source for the roots of the plant. sugars for the green leaf’s cellular respiration at night. sugars as an energy source for the roots of the plant. sugars to fuel the growth of the plant.
Answer:ATP as an energy source for the roots of the plant.
Explanation:
Photosynthesis is the process by which plants manufacture their own food. It involves the combination of water and carbon dioxide in the presence of sunlight. Sugars are produced in the process.
The ATP molecules produced during photosynthesis are not transported to plant root cells. Rather, metabolic activities within the plant root cells produces the energy molecules required by the plant roots.

Brain cells, which depend on glucose for energy, use the glucose transporter GLUT3, which has a Km of 1.5mM. Liver cells, which store glucose (as glycogen) after a meal and release glucose between meals, use the glucose transporter GLUT2, which has a Km of 15mM. Calculate the rate (as a % of Vmax) of glucose uptake in brain cells and in liver cells at circulated glucose concentrations of 3mM (starvation), 5 mM (normal levels), and 7mM (after a carbohydrate-rich meal). Use this rearranged M-M equation.
Answer:
Explanation:
Given that:
The brain cell which uses glucose transporter GLUT3 Km = 1.5 mM
The liver cell which stores glucose GLUT2 Km = 15 mM
The objective is to calculate the rate (as % of Vmax) of glucose uptake in brain cells and liver cells under starvation conditions.
Using the M-M equation i.e Michaelis- Menten equation;
[tex]Rate = \dfrac{V_{max}* [S]}{[S]+K_m}[/tex]
By rearrangement
[tex]\dfrac{Rate}{V_{max}}= \dfrac{[S]}{[S]+K_m}[/tex]
where;
[tex]V_{max}[/tex] = maximum velocity of a reaction
Thus; the rate as a % of Vmax of glucose uptake in brain cells is calculated as:
[tex]\dfrac{Rate}{V_{max}}= \dfrac{[3 \ mM]}{[3 \ mM]+1.5 \ mM}[/tex]
[tex]\dfrac{Rate}{V_{max}}= \dfrac{3 \ mM}{4.5 \ mM}[/tex]
[tex]\dfrac{Rate}{V_{max}}=0.667[/tex]
[tex]\dfrac{Rate}{V_{max}}=66.7 \%[/tex]
the rate as a % of Vmax of glucose uptake in liver cells is calculated as:
[tex]\dfrac{Rate}{V_{max}}= \dfrac{[3 \ mM]}{[3 \ mM]+15 \ mM}[/tex]
[tex]\dfrac{Rate}{V_{max}}= \dfrac{3 \ mM}{18 \ mM}[/tex]
[tex]\dfrac{Rate}{V_{max}}=0.166[/tex]
[tex]\dfrac{Rate}{V_{max}}=17 \%[/tex]
Thus, the uptake is larger brain cells due to the fact that the brain cells GLUT3 have higher tendency to attract glucose.

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.

Explanation:
Enzymes are proteins that have a three dimensional shape that is specific to a particular substract. environmental conditions can change. the shape of protein
Answer:
The enzyme will no longer be able to catalyze the reaction with the substrate
Explanation:
Enzymes usually have a very specific structure than holds the substrate molecules, facilitating the optimal environment for the reaction to proceed. This reduces the activation energy required to start the reaction.
If the shape changes, the substrate molecule will no longer properly fit. Therefore, the enzyme will not be able to catalyze the reaction.
