What do all forms of active transport have in common?

Answers

The forms of active transport that should be in common is by using the ATP.

Forms of active transport:

The plasma membrane should be selected also capable for controlling the movement of the substance via the passive transport where it does not use the energy and the active transport means when it needs the chemical energy in the form of ATP.

The interior of the cells should be highly concentrated glucose that shows an high energy storage molecule.

Answer:

-Using ATP

Explanation:

Cells use various mechanisms to move substances across their plasma membranes. Plasma membranes are selectively-permeable and capable of controlling all movement of substances through:

  • passive transport,  which does not use energy;
  • and active transport which requires chemical energy in the form of ATP.

Active transport involves the movement of substances out of cells against their gradients. For instance, glucose is transported across the membrane with specialized carrier proteins embedded within the membrane, and active transport; the cell's interior is highly concentrated- glucose is a high energy storage molecule required by many metabolic processes and required in high amounts.

Which of the following is true of RNA compared to DNA?a. It lacks phosphate groups.
b. It is a single-stranded molecule.
c. Its nucleotides do not have sugars.
d. It contains four different nucleotides.

Answers

The correct answer is B. It is a single-stranded molecule. It does not lack phosphate group but rather has a different one so there's also 4 but they're a bit different. Unlike the DNA that is a double spiraling strand, the RNA is just a single strand that goes on and on. Although similar, it does completely different things from the DNA.

Final answer:

RNA is a single-stranded molecule, in contrast to the double-stranded structure of DNA.

Explanation:

b. It is a single-stranded molecule.

RNA is a nucleic acid that is similar to DNA, but with a few key differences. One of these differences is that RNA is single-stranded, while DNA is double-stranded. This means that RNA is made up of only one chain of nucleotides, while DNA has two chains that are complementary to each other.

Other differences between RNA and DNA include:



  1. RNA contains the sugar ribose, while DNA contains the sugar deoxyribose.
  2. RNA uses the nitrogenous base uracil, while DNA uses thymine.
  3. RNA is typically shorter than DNA.

An aquatic food web consists of phytoplankton → krill → seals → sharks. The removal of which component is MOST LIKELY to cause an immediate impact on the food web?

Answers

Answer: The correct answer is-

phytoplankton .

In the given food chain of aquatic ecosystem, Phytoplanktons occupy the first trophic level ( as they form the base of the food chain) and they are called producers ( synthesize their own food using carbon dioxide and water in the presence of sunlight).

The energy is then transferred to the subsequent trophic levels from phytoplanktons to consumers ( krill, seals, and sharks).

If phytoplanktons are removed from the food chain, there will be no food available for krill and they will start to decline, which will eventually cause the decline in the subsequent trophic levels ( that is seals and shark).

Thus, phytoplanktons is the right answer.

Removing the Phytoplankton would cause an impact in the food web as its a keystone species without it the krill wouldn't survive meaning that anything that eats the krill or anything thing that eats what eats the krill would all die out

You have to really compare your options. Fix the legs, the arms and the choices. If you have three green eggs and hams, then a 4x4, take that and help the mitosis stick with something like spaghetti. Thank you :)

in order to use the Hardy-Weinberg equation to calculate genetic variations in a population which of the following conditions must exist in the population

Answers

Answer: All organisms must reproduce.

Explanation: Trust me G

APEX. Just trying to help people out who also have this question.

Population of living creatures or living organisms.

Because what can reproduce is a living creature/organism.

Further explanation

The Hardy-Weinberg Principle states that alleles and genotype frequencies in a population will remain constant from generation to generation without any other evolutionary influence. These influences include perfect pairing, mutation, selection, genetic drift, gene flow, and Meiosis steering.

The seven assumptions underlying the Hardy-Weinberg equation are as follows:

  • Such organisms are diploid
  • only reproduce sexually
  • generation that does not overlap
  • random marriage
  • infinite population size
  • same frequency alleles in both sexes
  • no migration, mutation or selection
