Antoni van Leeuwenhoek and Robert Hooke first discovered the presence of the microorganisms in the environment during 1665-1683. Using the microscopes, the discovered that there are many tiny life forms that are not visible to the naked eye. This discovery led to the shattering of the belief that the life forms can appear out of the ruined non-livings forms, and gave rise to the cell theory.

The cell theory states that the cells are the basic unit of the life, and every living organism is composed of these cell(unicellular) or cells(multicellular). The new cells arise from the already existing cells.

Hence, the answer is cell theory.

9. How did life on Earth change from one period of geologic time to the next?​
xxMikexx [17]

Answer:

Scientists use the geologic time scale to illustrate the order in which events on Earth have happened. ... They used relative dating to divide Earth's past in several chunks of time when similar organisms were on Earth. Later, scientists used absolute dating to determine the actual number of years ago that events happened.

Answer:

The role of carbon in biological systems is to allow the formation of organic molecules, in addition to providing energy for living beings.

Explanation:

Carbon is the fourth most abundant element on earth and one of the main elements of the viological systems, and its presence is essential for life on the planet to be maintained.

Carbon is necessary for all living beings, without exception. This is because it is used in the construction of organic molecules without which no living thing can survive, in addition to providing energy when it participates in sugar molecules, such as carbohydrates.

In certain bacteria, an oval shape (O) is dominant over round (o) and thick cell walls (T) are dominant over thin (t). Draw on a
seropon [69]

Answer:

Consider the heterozygous oval, thick cell walled bacteria to have the alleles OoTT and the thin cell walled bacteria to have alleles oott. Results will be 50% oval, thick walled bacteria and 50% round, thick walled bacteria. This will be the F1 progeny.

When the oval, thick walled bacteria from the F1 progeny is cross bred with round, thick walled bacteria then 25 percent of the bacteria will be heterozygous oval, thick walled. 25 percent will be heterozygous oval and heterozygous thick walled. 25 percent will be round and thick walled. 25 percent will be round and thin walled.

The expression 40x2 – 65x + 50 represents the sum of the interior angles of a regular pentagon in degrees. If the interior angle
Nadya [2.5K]

Answer:

2(8x^2-13x+10)

Explanation:

There are 5 angle s in a pentagon and we are assuming are pentagon is a regular one so the angles are all congruent.

Let's let A represent the measurement of one of the those angles in our pentagon.

The sum of our angles in our pentagon would then be A+A+A+A+A or 5A.

But we are also given that this equals 40x^2-65x+50.

So that means 5A=40x^2-65x+50.

If we divide both sides by 5 we can find what one of our angles is in terms of x.  So let's do that A=8x^2-13x+10.

So we want to know the sum of two our angles, we want to know what is A+A or 2A.  2A=2(8x^2-13x+10).  To obtain that I just multiplied both sides of A=8x^2-13x+10 by 2.

Synthesized RNA

Explanation:

  • Oligonucleotide synthesis is the characterized chemical structure (sequence) and short pieces of nucleic acids
  • The Manufactured <em>oligonucleotides are single-stranded DNA or RNA atoms around 15–25 bases long  </em>
  • <em>The middle loop carries a nucleotide triplet called the anticodon</em>  
  • Binding with a particular codon in the mRNA by explicit<em> RNA-to-RNA </em>base matching. Since codons in mRNA are perused in the 5′ → 3′direction, anticodons are situated in the 3′ → 5′ direction
