<u>Answer:</u>

CCGAGU

<u>Explanation:</u>

DNA transcription:

DNA transcription is the process through which DNA double helical strand is converted into single stranded RNA molecule.

During transcription two strands of DNA are named differently i.e Template strand and coding strand.

Template strand:

Strand from which RNA is producing is known as template strand while

Coding strand:

The strand which is opposite to the template strand is known as the coding strand. Coding strand is the DNA strand whose nucleotide sequence resembles to the RNA transcript base sequence except thymine which is replaced by uracil.

Correct Answer:

Template strand from 5' to 3' reads GGCTCA. and

In this question CCGAGT is coding strand.

RNA sequence is same as coding sequence except T which is replaced by U so sequence of RNA becomes

The correct answer is option B

Species interactions are categorized based on their reciprocal effects (the effects that the interaction has on each species/individual involved).

1. Bees pollinate plants as they move from flower to flower collecting pollen.

This is a mutualistic relationship because the both species involved in this interaction benefit from the interaction. The bee benefits because it obtains nectar which is provided by the plant. The plant benefits because the bee carries the plants pollen to other plants, allowing the plant to reproduce.

2. Green algae grow on the backs of spider crabs living in shallow water.

This is another example of a mutualistic relationship because both species involved in this interaction benefit from the interaction. The spider crab benefits from the camouflage that the algal growth provides, while the algae benefits from the protection from predators provided by the spider crab.

3. Fleas living on skin of dogs and obtaining nutrients from dogs blood.

This is a parasitic relationship because one of the species benefits from the interaction while the other species in negatively impacted by the interaction. The flea benefits from the nutrients obtained from the dogs blood while the dog is negatively impacted by the fleas presence (loss of blood, discomfort).

4. Nitrogen-fixing bacteria obtain nutrients from host plants and use the nitrogen to supply host plants with nitrogen.

This is an example of mutualism because both species in this interaction are benefitting from the interaction. The nitrogen fixing bacteria benefit by receiving nutrients from the host plant while the host plant is benefitting from receiving nitrogen from the bacteria.

What is the losing of water from organic molecules, then the joining of these molecules.
Vikentia [17]
Osmosis is a passive transport which moves water molecules from higher to lower gradient.
<span>Osmosis then is the movement of water particles from which has water and from which has not and to provide it with the sufficient H2O.<span> 

</span></span><span>The concentration of salt in water affects the rate of osmosis because it will determine how much water should be transported or excreted or to be taken in. The cellular process is keen to the salt concentration of its system thus making sure to maintain balance between the salt concentration the right amount of water must also be in its area of release for any expected occurences.<span>

Bacillus anthracis can cause infection via three different portals of entry. The ID50 of cutaneous anthrax is 10 to 50 endospore
dimulka [17.4K]

Answer:

It is significantly easier to be infected with cutaneous anthrax as compared to other forms of anthrax.

Explanation:

LD50 is the lethal dose that can cause adverse effects and death. The LD50 of cutaneous anthrax is too low as compared to inhalation and gastrointestinal anthrax which means that only few Bacillus anthracis endospores can cause infection via cutaneous route while other routes require at least 200 times greater quantity to cause infection.
