The answer to the above question is Fatty acids.

<h3>What are Fatty acids?</h3>

A fatty acid is a carboxylic acid with an aliphatic chain that is either saturated or unsaturated. This definition applies to chemistry, particularly biochemistry. The majority of naturally occurring fatty acids have an unbranched chain with 4 to 28 carbon atoms, which is an even number. In some species, like microalgae, fatty acids make up a significant portion of the lipids (up to 70% by weight), but in other organisms, they are present as one of the three main types of esters: triglycerides, phospholipids, or cholesteryl esters rather than in their solo form. Fatty acids are crucial nutritional sources of energy for animals in any of these forms, as well as crucial cellular building blocks.

A hypothesis is a ___.
Aloiza [94]

Answer:

A hypothesis is a tentative/ preliminary statement of the relationship between two or more variables. <u>It is a specific, testable prediction about what you expect to happen in a study.</u>

Explanation:

In science, the hypothesis is an idea or explanation that you then experience/test through study and experimentation. Outside science, theory or guess can also be called a hypothesis. The hypothesis is nothing more than an unbridled, wild guess but less than a well-established theory.

So, we can conclude that <em>The hypothesis</em><u> is a simple statement that defines what you think the outcome of your experiment will be.</u>

<em>Hope</em><em> </em><em>this helps</em><em>.</em><em>.</em><em> </em>

<em>Good</em><em> </em><em>Luck</em><em>!</em>

During DNA replication, a complementary strand of DNA is made for each original DNA strand. Thus if a portion of the original st
Sidana [21]

Answer:

agcttgagt

Explanation:

DNA is a double helix molecule composed of two complementary DNA strands which are in turn composed of four different nucleotide bases: Adenine (A), Guanine (G), Cytosine (C) and Thymine (T). In the DNA molecule, G and C are bound together as a base pair, while A and T are bound together as another base pair. This complementary base pairing structure means that both DNA strands are complementary to each other. In this case, since the sequence of one strand is "TCGAACTCA", the complementary DNA strand would have the sequence "AGCTTGAGT".

The fossil of a plant reveals that it produced spores that were used for reproduction. Which type of plant was it
raketka [301]

Answer:

It was a non-seed-bearing plant, or sporophyte, such as a moss, liverwort, or hornwort.

Explanation:

All plants have spores as part of their life cycle (alternating between sporophyte, which is asexual, and gametophyte, which uses sexual reproduction), but because the spores of this  fossilized plant were used for reproduction, this plant most likely did not produce any seeds.
