Most plants and animals in the world reproduce by sexual reproduction. Which process is responsible for the genetic variation found in organisms that reproduce this way?

Answers

Answer 1
Heyyy
I guess the answer would be because of meiosis in meiosis this is because in prophase the two chromosomes cross over and the genes are mixed leading a random mix of characteristics. Mutations can also cause these differences so the offspring are different and not the exact copy as parents.

I hope this helps ❤️

Jelly fish like a smack punch.

Explanation:

The mystery of what kind of punch a jellyfish like matched in beautifully with the show's theme - and explained why they're dubbed Scorpion. Scorpions are strongly loyal to the other members of their cyclone group. As they solve their cases, the squad surely creates a ruckus! Scorpions, like other scorpions, have very hard shells and are disliked by many people. A smack is a bunch of jellyfish, and the answer to the riddle is a clever play on the term punch. And, of course, this is what the marines called the team at the start of the show when they intended to make fun of them.

Match the digestive organ on the left with its function.

Answers

Answer:

pancreas: secretes digestive enzymes into the small intestine

esophagus: the place where peristalsis takes place

small intestine: area of the digestive tract where most nuturients are absorbed

stomach: area of the digestive tract that follows the esophagus

large intestine: area of the digestive tract where mostly water is absorbed

Explanation:

peristalsis: so the food can move down towards your stomach, independently of gravity

pancreas: helps your stomach become the ultimate weapon to destroy anything that gets in there with its enzymes

small intestine: it is really really long -> more time to absorb nutrients

large intestine: like a farm of bacteria, the most exotic things that somehow made it through all the way here are finally destroyed -> also, water absorbtion: your body wants to retain as much as possible, this is how and where stool formation takes place

The illustration below represents____,
which is responsible for genetic diversity.

Answers

Answer: Crossing over

Explanation: This is what a crossing over gene looks like it starts together and separates here is evidence below ⬇️

The illustration below represents the crossing over stage in meiotic cell division which is responsible for the genetic diversity in organisms. Thus, the correct option is B.

What is Crossing over?

Meiosis is the type of cell division during which the chromosome number in the daughter cells become half of that present in the parent cells from which they are produced. From one parent cell four daughter cells are formed in meiosis.

Chromosomes forms the chromatids in the cell which form tetravalent with the non-sister chromatids of the homologous chromosomes. This stage is called crossing over where the genetic material present in each of the chromatids are exchanged which results into genetic diversity in a species. After the crossing over stage, the chromatids separate from each other and goes to different daughter cells.

Therefore, the correct option is B.

Which of the following correctly describes the two phases of the cell cycle?
A. Cells grow and develop during interphase. Cells reproduce during the mitotic phase.
B. Cells grow and develop during the mitotic phase. Cells reproduce during the interphase.
C. The nucleus of a cell divides during interphase. The cytoplasm of a cell divides during mitotic phase.
D. The nucleus of a cell divides during mitotic phase. The cytoplasm of a cell divides during interphase.

Answers

Answer: the answer is A

Explanation:

Cell cycle refers to the series of processes that leads to the growth/development and division of a cell. The cell cycle uses MITOSIS for cell growth. Mitosis comprises of two distinct stages namely: INTERPHASE AND MITOTIC PHASE. The interphase is referred to as the resting phase of the cell in which the cell grows and develops.

On the other hand, MITOTIC PHASE is the stage where the actual division of the nucleus (karyokinesis) and cytoplasm (cytokinesis) generally called CELL DIVISION occurs. Therefore, the cell reproduces i.e. one cell forming two, in the mitotic phase.

2.) What is the start codon? What are the 3 stop codons?

Answers

The amino acid sequence here is Met-Ser-Asp-Trp.  The start codon is AUG, while the three stop codons are UAG, UAA, and UGA.

The triplets of nucleotides or codons in mRNA determine the order of amino acids that will be added to the protein during translation.

The start codon in the genetic code is AUG and it encodes for the amino acid methionine (Met).

The 3 stop codons in the genetic code are UAG, UAA, and UGA. These codons do not code for an amino acid.

The distinguishing visible features of each stage of the cell cycle include chromosome condensation, mitotic spindle, equatorial plate and formation of two cells.

What is the cell cycle?

The cell cycle is a series of well-defined steps in the life of a cell that begins with cell growth and end with its division.

The cell division has a series of steps that may be classified according to the phenomena that occur in these phases.

For example, chromosomes condense during the first stage of cell division (prophase), where they migrate to the equatorial plate at metaphase.

In conclusion, the distinguishing visible features of each stage of the cell cycle include chromosome condensation, mitotic spindle, equatorial plate and formation of two cells.
