Independent assortment occurs only in cells that are heterozygous for two genes (AaBb) and not in cells that are completely homo
fomenos

Answer:

False

Explanation:

Gregor Mendel, who was referred to as the FATHER OF GENETICS, discovered the principles that governs heredity. One of those principles which he called LAW OF INDEPENDENT ASSORTMENT states that the alleles of a gene randomly segregates into gametes independently of the alleles of another gene. This means that during gamete formation (meiosis), the separation of the alleles of one gene doesn't affect the separation of the alleles of another gene.

Mendel discovered this principle when he worked with two genes that was responsible for two distinct characters. Hence, in a cell that contains two genes responsible for two different characters in the organism, independent assortment will always occur during gamete formation. Although, in an organism that is homozygous for both traits (AABB or aabb), only one type of allelic combination will be produced in the gamete. However, the alleles will still randomly align and separate independently of one another during Metaphase and Anaphase stages of meiosis.

Lina20 [59]

Answer:option C= mRNA

Explanation:

MACROMOLECULES are large molecules, such as protein, commonly created by the polymerization of smaller sub-units called monomers.

The NUCLEAR PORE is a protein-lined channel in the nuclear envelope. The NUCLEAR PORE regulates the transportation of molecules between the nucleus and the cytoplasm. In eukaryotic cells, the nucleus is separated from the cytoplasm and surrounded by a nuclear envelope.

mRNA is synthesized by DNA during a process known as the TRANSCRIPTION. After the synthesis, the new molecule moves from the nucleus to the cytoplasm. It passes through the nuclear membrane through a NUCLEAR PORE. Then, it will later join with a ribosome, which is just coming together from its two sub-units, one large and one small.

kondor19780726 [428]

Through "cellular respiration" process energy is stored in the form of glucose.

<u>Answer:</u> Option A

<u>Explanation:</u>

The series of metabolic reactions and mechanism take place in organism ranging from microscopic bacteria to large organisms cells in order to transfer biochemical energy from food nutrients (stored in glucose form which is transferred) to adenosine triphosphate (ATP) and then waste product is also released, the whole process is known as "cellular respiration".

The energy required for ATP synthesis extracted from the breakdown of foods and phosphocreatine (creatine phosphate). It is stored inside muscle cells because phosphocreatine is readily available to produce ATP quickly.
