Answer:
The correct answer is density-dependent factor.
Explanation:
The factors whose influences on the growth or size of the population changes with the density of the population are known as the density-dependent factors. The availability of food, disease, predation, and migration are some types of density-dependent limiting factors.
One of the density-dependent factors in nature is predation, predation confines various populations. The population of the prey and the predator encircle towards each other, with the population of the predator somewhat lagging behind the population of the prey.
With the increase in the population of the prey, the predator gets more to eat, and thus the population of the predator increases. With the increase in the predator population, pressure imparts on the prey population and it starts to decline. The decline in the availability of the food eventually makes the population of the predator to decline. Therefore, it can be seen that both the population of the prey and the predator are affected by predation, that is, a density-dependent factor.

Select the statements that accurately describe endocytosis.
a. The cell forms proteins that move substances into the cell against a concentration gradient.
b. The cell selectively filters small nutrients through specialized membrane pores.
c. The cell membrane pinches off to form an extracellular vesicle joined to the cell by filaments.
d. The cell membrane engulfs a particle in the cytoplasm and forms a vesicle around it.
e. The cell expends energy to transport materials into the cytosol.
Answer:
The correct answer is:
The cell membrane engulfs a particle in the cytoplasm and forms a vesicle around it. (d.)
Explanation:
Endocytosis is a type of active transport, where particles such as (large molecules, parts of cells, and even whole cells) are moved into cells.
The various types of endocytosis has a common feature of:
1. invagination of plasma membrane forming pockets around the target particle.
2. the pocket pinches off from original plasma membrane
3. forming a new intracellular vesicle containing the target particle.
The different types of endocytosis includes
a. pinocytosis (cell drinking): takes in extracellular fluids
b. phagocytosis (cell eating): large solid particles are taken in by cells
c. receptor-mediated endocytosis: here, receptor proteins on the cells surface, binds to complementary proteins on the surface of the target particles before endocytosis occurs.
What type of acid is currently of principal concern when dealing with acid rain?
Answer: Sulfur dioxide (SO2) and nitrogen oxides (NOx) released into the air by fossil-fuel power plants, vehicles and oil refineries are the biggest cause of acid rain today, according to the EPA. Two thirds of sulfur dioxide and one fourth of nitrogen oxide found in the atmosphere come from electric power generators

How does science directly affect you? Where will what you have learned lead you next? PLEASE HELP ME RIGHT NOW!!!!!!!
Answer: Literally everywhere. Having an at least basic level of science helps you in day-to-day situations. For example, cooking. Not only is it crucial to understand the chemical and physical processes when cooking, you should also understand the complexity of how these micro and macromolecule exchange processes affect you and your body. Another prime example is your health, or human processes. You might not realize this, but your body is a plethora of complex, interconnected systems and networks that work hard 24/7 to maintain homeostasis (keep you alive). Understanding how our human physiques conduct themselves helps us gain the knowledge to be able to stay alive.
You prepare an agar plate by spread plating & place an antibiotic disk in the middle of the plate. After incubating for a day at 37 degrees C, there are no bacteria on the plate. Which of the following is NOT a reasonable interpretation of what might have happened?
O The bacteria in the culture tube were already dead when you made the plate
O The medium used was defective and provided no nutrition for the bacteria
O The bacteria grew all over the plate but were then killed by the antibiotic
O The spreading tool was too hot when spreading the bacteria
Answer:
A.The bacteria in the culture tube were already dead when you made the plate
Explanation:
Antibiotics are the chemical substance used to kill or stop the growth of bacteria and some other microorganism.
Antibiotics are added to agar plate during experiment for the selection of only those bacteria with resistance to that antibiotic.
There can be several interpretation for the absence of bacteria such as:
The bacteria grows on the nutrients in the medium but due to defective medium they were unable to grow and die.It may also happen bacteria might have grown in all over the plate but due to the action of antibiotic, all the bacteria got killed.Tool used for spreading might kill bacteria as it was hot and bacteria may not be able to tolerate the excessive heat and die.Hence, the only not reasonable interpretation is bacteria in the culture tube were already dead when you made the plate.
So, the correct option is A.
Is the role of the liver

Light dependent reactions
Explanation:
DPIP stands for Dichlorophenolindophenol. It is a chemical compound that is used as a redox dye.
DCPIP is blue when it is oxidized DCPIP is colorless when it is reduced.
DCPIP measures the rate of photosynthesis. The redox dye is decolorized by chemical reduction when it is exposed to light in the process of photosynthesis.
DPIP was used in the photosynthesis lab to measure the light dependent reactions.
