Most human cells range from 10 to 15 micrometers in diameter. What limits how large a cell can get
Mice21 [21]

The relationship between its volume and surface area limits how large a cell can get.

<h3>What is cell range?</h3>

The range of a cell is defined as the quantity of material that can be found within a cell with respect to the surface area.

The range of a cell is limited by the volume and the surface area which means that the wider the surface area the more volume the cell can contain.

How are red blood cells able to move through narrow vessels to carry oxygen throughout a multicellular organism? (1 point) a)The
geniusboy [140]

Answer:

The correct answer is - option B. They are small because they lack a nucleus.

Explanation:

Red blood cells or erythrocytes are specialized cell that produce in bone marrow and have specific role such as carrying oxygen from lungs to deliver it to the various organs and carry out carbon dioxide.

In mammals these cells lack cell organelles such as nucleus and mitochondria, a major factor that determined its smaller size. The size of RBC are move through narrow vessels throughout a organism because of its specific size and shape that provide it space for hemoglobin and allow to be flexible and bend to move through narrow vessels.

Thus, the correct answer is : option B. They are small because they lack a nucleus.

In this metabolic process, the enzyme RNA polymerase binds RNA nucleotides (the substrates) together by catalyzing the formation
stira [4]

Answer:

TRANSCRIPTION

Explanation:

Transcription is the first process that occurs in the expression of a gene. It involves the synthesis of a mRNA molecule from a DNA template. The DNA molecule, which is located in the nucleus of an eukaryotic cell, is bound to by an enzyme called RNA polymerase in order to synthesize an mRNA molecule/strand.

RNA polymerase synthesizes a mRNA molecule using complementary base pairing rule i.e. Uracil base (U) is synthesized when Adenine (A) is read, Adenine when Thymine (T) is read, Guanine (G) when cytosine (C) is read, Cytosine when guanine is read. These nucleotide bases are then joined together via chemical bonding.

In a nutshell, RNA polymerase catalyzes the formation of a bond between the backbone sugar of one nucleotide base to the backbone phosphate of another nucleotide base in the metabolic process of TRANSCRIPTION.
