Brainliest:Both the euglena and paramecium seen here have___?
forsale [732]

Answer:

projections that help them move

Explanation:

Euglena and paramecium both belong to the Kingdom Protista. They are very minute single cellular organisms but have many differences among them. Paramecium is more similar to animals in many of its characteristics while Euglena is more similar to plants in its characteristics. This is because Euglena just like plants can make their own foods through chloroplast while paramecium just like animals cannot make own food.

However what is common in both of these are projections that help them move . Paramecium have projections called cilia around the whole body while Euglena has a whip like flagella which helps it to move.

Hope it help!

The value of photosynthetically active radiation above which no further increase in photosynthesis occurs is referred to as:
makkiz [27]
The right answer is <span>the light saturation point.

More light usually results in higher photosynthesis levels. However, with the increase of the intensity of the light, the photosynthesis rate eventually reaches a maximum point. This point is called "luminous saturation point".

When this point is reached, the intensity of the light does not increase the rate of photosynthesis and the rate of photosynthesis curve ceases to increase.

alexdok [17]
<span>tRNA carries a single amino acid to the ribosome. 
It fits the codon on the mRNA in the ribosome with it's anti-codon. 

The ribosome has peptidyl-transferase activity which catalyses the peptide bond between 2 amino acids on 2 tRNAs in the ribosome. 

One tRNA is released and then picks up another amino acid depending on its anti-codon.

Explain the importance of immunological memory cells. Describe in detail how and when memory cells arise and explain how they fo
Vlad1618 [11]

Explanation:

<em>Immunological memory</em> is the property of the immune system to store information about a stimulus so it can mount an effective response if it encounters the same stimulus again being this second response quicker and stronger even after years since the first encounter.

This kind of response is dependent on many subpopulations within T and B lymphocytes and NK cells. When encountering an antigen, B cells recognize it by membrane antibody specifically binding to the antigen and then being activated to expand rapidly with their progeny clones differentiating into plasma and memory B cells, these last ones have a long life span to remain in the body, ready when another encounter with the same stimulus occurs, this is how the basis for effective immunizations happens.

I hope you find this information useful! Good luck!
