Answer:

The incorrect statement is : Decreased surface-to-volume ratios to increase the efficiency of gas exchange in air

Explanation:

the fundamental problem that an aquatic animals face during its progress to land to save the egg or embryo from parching. So they have developed cleidoic eggs where undeveloped organism stay implanted inside extra embryonic layers, for example, amnions and are secured in egg shells. These eggs have minute pores so embryo can make gas exchange.

This egg shells forestall water misfortune. Interior treatment, however are available in certain sharks, yet it is for the most part a variation of land creatures. Explicit intromittent organs have been created for moving of sperm in to female. In contrast with water , gaseous movement is in land creatures is happen through advancement of lungs which contain numerous alveoli where gaseous exchange is occurred. Decreased surface to volume ratio decrease productivity of gas exchange , not increment.

Thus, The incorrect statement is : Decreased surface-to-volume ratios to increase the efficiency of gas exchange in air

What is a stop codon​
storchak [24]

Answer:

In the genetic code, a stop codon (or termination codon) is a nucleotide triplet within messenger RNA that signals a termination of translation into protein

Explanation:

Proteins are based on polypeptides, which are unique sequences of amino acids. Most codons in messenger RNA (from DNA) correspond to the addition of an amino acid to a growing polypeptide chain, which may ultimately become a protein. Stop codons signal the termination of this process by binding release factors, which cause the ribosomal subunits to disassociate, releasing the amino acid chain. While start codons need nearby sequences or initiation factors to start translation, a stop codon alone is sufficient to initiate termination.

17. Which of the following statements are accurate?
Naddik [55]

Answer:

A. Neurotransmitters can act as ligands.

B. Acetylcholine is a neurotransmitter. It can bind to an acetylcholine receptor on the surface of a cell. If this receptor is also a sodium channel, we would call acteylcholine a ligand and its receptor a ligand gated receptor.

Explanation:

Answer:

A. Neurotransmitters can act as ligands.

B. Acetylcholine is a neurotransmitter. It can bind to an acetylcholine receptor on the surface of a cell. If this receptor is also a sodium channel, we would call acteylcholine a ligand and its receptor a ligand gated receptor.

Explanation:

Neurotransmitter are chemicals that transfer signals between neurons and nerve cells. They control some physical and physiologocal activity such as appetite, food.

Acetycoline is an example of neurotransmitter and it is located in the parasympathetic nervous system. Ligand are substance that form complexes with biomolecule. They serve biological purpose with this biomolecule.

This ligand binds to target site. Neurotransmitter act as ligand by binding to receptor in the postsynaptic neuron and acetycoline a type of neurotransmitter can also serve as ligand they bind to acetycoline receptor on cell surface.

HELP!!!! Time crunch!
Mila [183]

Answer:

Glycolysis is a series of reactions that take place in the cell cytoplasm. It involves the oxidation of glucose into pyruvate (a 3 carbon compound), that produces (overall)ATP and reduced NAD: an enzyme that carries hydrogen. The number of carbons in each of these compounds is indicated in the green circle.

The carriers FAD and NAD bring the hydrogen and it separates to H+ and electrons (e-). The electrons pass from carrier to carrier and loose energy. This is used to synthesize ATP.

However, there are a lot of hydrogen ions, that unless they are removed, they'll cause a large increase in pH. Therefore, oxygen reacts with the ions to remove it and produce water. This is what the oxygen you inhale is used for (in terms of respiration).
