Answer:
Plants perform both photosynthesis and cell respiration and cause a net decrease of carbon in the atmosphere.
Explanation:
Plants are living organisms capable of performing a process called photosynthesis, which they use to synthesize their food (sugar). They use carbon in form of carbon dioxide, which they absorb from the atmosphere via their stomata.
However, plants like every other living organism, also perform cellular respiration. Cellular respiration releases carbon in form of carbon dioxide into the atmosphere. Plants use more carbon dioxide than they release into the atmosphere, hence, they contribute to global carbon cycle perform both photosynthesis and cell respiration and cause a net decrease of carbon in the atmosphere.

Question 1: pH
To begin with, you remember that acids are at a pH below 7, bases are above 7, they turn litmus paper red or blue, and water is neutral. To further brush up your memory, you can refer to buffers. You decide to investigate further. Run the pH simulationand open the ‘Micro’ investigation. Notice on the simulation screen:
The pull down menu of substances at the top right
The 3 adjustable faucets on the right
pH scale in the middle
water components on left
Look at how the settings change with different substances.
Choose a substance such as battery acid (a 1.0 molar solution) with a pH of 1.0. Check the molecule and ratio boxes on the bottom of the screen.
Your objective is to discover what happens to the pH of battery acid when it is diluted with water. To find out, adjust the amount of battery acid to 0.5 liter (bottom faucet) and add water (top right faucet) to restore the volume to 1.0 liter (0.5 M).

How has the development of a pine and then a hardwood forest affected populations of shrubs?
The development of the two types of forests has negatively affected populations of shrubs
Answer:
Yes, shrubs are affected.
Explanation:
The development of a pine and then a hardwood forest affected populations of shrubs because pine and hardwood trees are higher in length than shrubs so the shrubs did not gain sunlight and also all the nutrients present in the soil is extracted by the pine and hardwood trees. The shrubs present below the pine and hardwood trees slowly removes from that environment due to unavailability of sunlight and nutrients.

Parathyroid hormone (PTH) is secreted in response to a drop in calcium levels in the blood. The secretion of PTH is regulated by a negative feedback mechanism. What can you expect to happen to calcium blood levels as increased amounts of PTH are secreted? Why
Answer:
An excess of calcium in the blood produces a disorder called primary hyperparathyroidism.
Explanation:
Calcium is a mineral found mostly in bones, where it builds up and keeps them strong. There is also a small amount of calcium in the muscles and blood cells, where it performs several important functions. When the calcium level is low, the parathyroid glands (four small glands located in the neck) produce a hormone called parathyroid hormone. Its main metabolic function is to maintain the levels of ionic calcium in the blood and phosphate within normal limits. Hyperparathyroidism is a disorder that lies in the parathyroid glands themselves, in such a way that an excessive and autonomous secretion of parathyroid hormone is produced from them, which changes the metabolism of calcium producing hypercalcemia and bone structural alterations. It is usually caused by the presence of autonomous adenomas, which affect a single gland. Excess calcium in the blood can lead to osteoporosis (weakening of the bones) and kidney stones.

compare and contrast the different types of heterotrophs Use the terms Carnivore, herbivore, and omnivore in your discussion to get full credit.
Answer:
I'm not sure if your asking about a A, B, C, D question but, as far as I can tell this is what I know
Explanation:
(:Comparing:) Heterotrophs occupy the second and third levels in a food chain, a sequence of organisms that provide energy and nutrients for other organisms. ... Herbivores—organisms that eat plants—occupy the second level. Carnivores (organisms that eat meat) and omnivores (organisms that eat plants and meat) occupy the third level.
(:Contrasting:) Examples include plants, algae, and some types of bacteria. Heterotrophs are known as consumers because they consume producers or other consumers. ... Herbivores—organisms that eat plants—occupy the second level. Carnivores (organisms that eat meat) and omnivores (organisms that eat plants and meat) occupy the third level.
Hope this helps.
Heterotrophs are organisms that depend on external sources for their foods. They are as opposed to autotrophs which have the capacity to produce their own foods via photosynthesis.
Heterotrophs are of 4 types mainly:
Carnivores: they feed on animals either by hunting and killing them (predators) or by feeding on carcasses (scavengers). Some feed on insects (insectivores)Herbivores: they feed on herbs or plants generallyOmnivores: they eat both plants and animalsDetritivores: they eat dead or decaying plants or animalsHence, apart from the fact that all heterotrophs depend on external sources for their foods, they differ based on the type of food they eat.

Answer:
They frequently flip-flop from one side of the membrane to the other.
According to the fluid mosaic model of cell membranes, phospholipids frequently flip-flop from one side of the membrane to the other.
What do you mean by the Fluid mosaic model?The fluid mosaic model may be defined as the model of the plasma membrane that consists of two-layer of lipids and proteins molecules are embedded among the lipid bilayer.
Phospholipids have a hydrophobic tail which is found in the interior of the membrane, while a hydrophilic head is found on the outer side of the membrane.
These molecules frequently flip-flop from one side of the membrane to the other with the help of flippase, floppase, and scramblase.

The active transport pump used to move sodium ions across the membranes of gill cells in a freshwater fish has each of the following characteristics EXCEPT
IT USES OSMOSIS TO CARRY SODIUM IONS INTO THE CELL.
The active transport pump that is used to move sodium ions across the cell membranes of gill cells in freshwater fish has the characteristics of active transport system except that it uses osmosis to carry sodium ion into the cell.
During the process of active transport, there is use of energy by a protein pump in the form of ATP,this protein pump is to move molecules from an area of low concentration to an area of high concentration.
A good example of this active transport system is the sodium-potassium pump,this sodium-potassium pump moves sodium ion to the outside of the cell and moves potassium ion to the inside of the cell.
So that rules out the option stated above because it uses osmosis to move sodium ions into the inside of the cell instead of moving it outside the cell.
This question is incomplete because it is lacking the necessary answer options, which I have provided below:
A. It uses osmosis to carry sodium ions into the cells.
B. It requires energy.
C. It has a specific binding site for ATP.
D. It has a specific binding site for sodium ions.
So, given your question, the answer option which is not a characteristic of the active transport pump used to move sodium ions across the membranes of gill cells in a freshwater fish is: A. It uses osmosis to carry sodium ions into the cells.
A freshwater fish refers to the species of fish that spend a critical part or all of their lives in lakes, rivers, wetlands, etc., with a salinity level of less than one (1) percent.
Cell transport can be defined as the movement of ions, molecules, or substances across the cell membrane, either into or out of the cell of a living organism.
Basically, there are two (2) main types of cell transport and these include:
Passive transport: it involves the movement of substances across the cell membrane with the concentration gradient.Active transport: it involves the movement of substances across the cell membrane from a region of lower concentration to a region of higher concentration, against a concentration gradient and in the presence of oxygen.During an active transport, a protein pump uses energy in the form of adenosine triphosphate (ATP) to move molecules from a region of lower concentration to a region of higher concentration, against a concentration gradient.
For example, a sodium-potassium ([tex]Na^+ K^+[/tex]) pump moves sodium ions ([tex]Na^+[/tex]) outside the cells and moves potassium ion ([tex]K^+[/tex]) inside the cells as an active transport.
In conclusion, using osmosis to carry sodium ions ([tex]Na^+[/tex]) into the cells is not a characteristic of the active transport pump used to move sodium ions across the membranes of gill cells in a freshwater fish.
