The sharp, inch-long thorns of the crown-of-thorns sea star are its spines. These spines, unlike those of most other sea stars,

contain a potent toxin. If it were discovered that crown-of-thorns sea stars do not make this toxin themselves, then the most likely alternative would be that this toxin is _____.
A) derived from the nematocysts of its prey
B) absorbed from the surrounding seawater
C) an endotoxin of cellulose-digesting bacteria that inhabit the sea star's digestive glands
D) injected into individual thorns by mutualistic corals which live on the aboral surfaces of these sea stars

Answer:

The answer is A) derived from the nematocysts of its prey.

Explanation:

Sea stars mostly eat cnidarians (mollusks) which can contain a large number of nematocysts in their bodies. Therefore it would be possible that this toxin is absorbed from the prey.

mihalych1998 [28]

Answer:

c) degree of myelination of the axon

Explanation:

The myelin sheath covers many axons in central nervous system (CNS) ( by oligodendrocytes) and in the peripheral nervous system (PNS) (by Schwann cells). Their function is to insulate axons and to increase the speed at which information travels from one nerve cell to another.

Nerve conduction velocity is specific to each individual and depend on the level to which that axon is myelinated, but also on  an axon's diameter.

Sati [7]

The most ethical decisions for usage of genomic data and technology, like sequencing human genomes for customized treatments and constructing deadly pathogens for study, are based on Consensus.

<h3>Waht is Consensus in a scientific community?</h3>

It normally implies settlement of the supermajority, aleven though now no longer always . Consensus is executed via scholarly communique at conferences, the book process, replication of reproducible consequences through others, scholarly debate, and peer review.

In short, a systematic consensus tells us matters that we've already learned, and it shall be realized whilst matters have stopped being debated withinside the sciences.Scientific consensus is the collective judgment, position, and opinion of the network of scientists in a selected discipline of study.

Why would it be hard to find the CO2 level if the light intensity were very low? HELP!!!!
drek231 [11]
If CO2 was in very small amounts then it would be the limiting factor of photosynthesis, this means the process will take place at a much slower rate because it is lacking one of the raw materials it needs for the process to occur. To find the optimum light intensity you really need all other factors to be at optimum levels or in abundance.

yKpoI14uk [10]

Answer;

The mouth


For ingested foods, the first opportunity for enzymatic digestion occurs in the mouth.


Explanation;

The digestion of food starts in the mouth.

There is both mechanical and enzymatic digestion of food in the mouth. Mechanical digestion involves the mechanical break down of food using teeth to smaller particles thus increasing the surface are for the activity by enzymes.

Enzymatic digestion in the mouth involves enzyme salivary amylase which acts on starch to form maltose.
