Answer:

die

Explanation:

Food webs describe who eats whom in an ecological community. Made of interconnected food chains, food webs help us understand how changes to ecosystems — say, removing a top predator or adding nutrients — affect many different species, both directly and indirectly.

Phytoplankton and algae form the bases of aquatic food webs. They are eaten by primary consumers like zooplankton, small fish, and crustaceans. Primary consumers are in turn eaten by fish, small sharks, corals, and baleen whales. Top ocean predators include large sharks, billfish, dolphins, toothed whales, and large seals. Humans consume aquatic life from every section of this food web.

denis-greek [22]

Answer:

The inhibitory transmitter activates ligand-gated potassium channels

Explanation:

When a cell is in hyperpolarized state,the potassium gated channels are taken longer time to close up, Therefore, more K+ leaks out of the axoplasm to the exterior.Therefore the cell appears to continue in the resting state, with more negative value of the cell potential of (-120 mV) and this called hyperpolarization.

However, with the addition of inhibitory transmitter,the ligand-gated potassium channels are activated,Theses channels closes up.Then sodium gated channels, which were initially in refractive state reopens, sodium ions diffuses inwards for depolarization, and the neuron returns to depolarized state.

Which statements describe functions of antibodies? Select two options.

vodomira [7]

Answer:

This question lacks options, options are:

A.They maintain the cell’s shape.

B.They regulate cell processes.

C.They protect the body from infectious agents.

D.They signal the immune system to destroy pathogens.

E.They speed up biochemical reactions.

F.They send electrical signals.

The correct answers are C and D.

Explanation:

B cells and T cells use different biological weapons to attack the pathogen. The first secrete proteins called antibodies, which are distributed via the blood or the exposed surfaces to the environment, such as mucous. Antibodies are glycoproteins that circulate in the bloodstream looking for antigens that cause some type of damage to the body. Antibodies recognize and neutralize pathogens in a highly efficient way. Once the antibodies are produced, they remain circulating in the bloodstream for several months, which generates immunity for a long period of time to a certain antigen, in other words, they are capable of recognizing other molecules (antigens) in a very specific way and forming stable complexes with them (immune complexes). Its appearance in plasma is part of the adaptive immune response, in what is known as a specific humoral response, constituting a very effective defense against pathogens.

Which of the following statements is NOT true regarding ATP production in muscles during periods of prolonged energy use, such a

Marysya12 [62]

Answer:

C.In the absence of oxygen, creatine phosphate can drive aerobic respiration pathways for a few minutes.

Explanation:

C. In the absence of oxygen, creatine phosphate can drive aerobic respiration pathways for a few minutes.

This statement not true for a following reasons.

Firstly, creatine phosphate directly phosphorylates ATP instead of providing any support for aerobic pathways.

Secondly, creatine phosphate stores are used up in about 15 seconds only. Thirdly, a cell does not need oxygen deficit for creatine phosphate to be activated, it just needs to be short on ATP.
