Photophores are:

Biology
1 answer:
Kobotan [32]2 years ago
8 0

Answer:

B) cells or tissue that produce light

Explanation:

It wouldn't be A because photophores do not affect the color of other organisms.

It wouldn't be C because the cells produce light, they don't necessarily change color.

Lastly, it wouldn't be D because it isn't a whole organism producing the light, it's an organ. Organs are multiple tissues working together, and tissues are groups of cells.

When we doing strawberry extraction,why do we have to remove the air as much as possible before we seal the bag?
AlladinOne [14]

Answer:

Explanation:

Oxygen is needed to support life and some metabolic processes in microorganisms especially aerobic organism.

The presence of oxygen in the container gives them the opportunity to carry out there metabolic activities thereby enhancing there growth and multiplication.

Hence, to limit the growth of aerobic bacteria or fungi, and also to prevent the evaporation of volatile components that is available in the content oxygen is withdrawn this help extend the shelf life of the produce to be stored.

A species that has experienced a severe bottleneck event would be expected to _______.. a.. be better able to adapt to changing
romanna [79]

Answer;

C. Be more susceptible to disease and famine

Explanation;

-A species that has experienced a severe bottleneck event would be expected to be more susceptible to disease and famine.

-The Bottleneck Effect occurs when there is a disaster of some sort that reduces a population to a small handful, which rarely represents the actual genetic makeup of the initial population.

-It may be caused by various events, such as an environmental disaster, the hunting of a species to the point of extinction, or habitat destruction that results in the deaths of organisms.

TRNA molecules bring a specific ________________ to the ribosome, according to the ______________. *
Veronika [31]

Answer:

tRNA molecules bring a specific <u>amino acid</u> to the ribosome, according to the <u>mRNA codon</u>.

Explanation:

In the context of protein synthesis, an mRNA molecule contains the specific codons that encode the amino acids that will be part of the protein. The tRNA is in charge of bringing the amino acids to the ribosome, according to the specific information of the mRNA codons.

The function of tRNA depends on the complementarity that exists between the mRNA codon and the anti-codon tRNA, in such a way that :

  • <em>The pattern in the amino acid sequence of a protein is indicated by mRNA </em>
  • <em>tRNA has a complementary anticodon, so it will only bring the specific amino acid that the codon encodes.</em>

In general terms, each mRNA molecule possesses the genetic code that indicates the amino acid sequence of a protein, and tRNA helps bring those amino acids to the ribosome for synthesis to occur.

Which of these is a polysaccharide? A. Lactose. B. Glycogen. C. Sucrose.
geniusboy [140]

cellulose is a polysaccharide.

A significant class of biomolecules is polysaccharides. They are large chains of monosaccharide molecules that are linked together. These intricate biomacromolecules serve as a vital energy source for animal cells and are a crucial part of plant cells' structural makeup. The nature of the monosaccharides determines whether it is a homopolysaccharide or a heteropolysaccharide.

A branching polysaccharide is a type of carbohydrate that is different from a linear polysaccharide, which is a straight chain of monosaccharides.

Organisms have this energy in reserve. The molecules are hydrophobic because water cannot enter them because of the many hydrogen bonds present. They permit adjustments to the concentration gradient, which affects how the cells absorb nutrients and water.
