stira [4]2 years ago

Answer: Meiosis

Explanation:

Meiosis creates gamete "daughter cells" that have half the chromosomes as a normal cell that would be created during mitosis, which is the division and reproduction of identical cells from the parent. In humans, a regular 46 chromosome cell divides through meiosis to create gametes with 23 chromosomes. This is important to be sure that an organism that is made through reproduction with sperm and egg has the correct number of chromosomes.

Imagine that your lab is synthesizing a new type of cell. One of your colleagues suggests that your synthetic cell should use pr
Gnom [1K]

Answer:

In a scenario in which I have to synthesize a cell and decide why I have to pick one from Prokaryotic or eukaryotic because of their differences in the speed of the process. The characteristics that make it faster in prokaryotic cells are:

The primary transcript in prokaryotes does not undero further processing, so transation can begin immediatly.

Multiple proteins can be synthetized from a single polycistronic MRNA molecule.

Prokaryotes lack a nuclear envelope, so translation can begin on mRNA even before transcription of the mRNA is complete.

Explanation:

The nature of Prokaryotes makes them undergo the synthesizing process quicker than Eukaryotes because they don't require a preliminary process to start it as Eukaryotes have to undergo one. This is because their composition, Eukaryotes are cells without many organelles like mitochondria or even nucleus. this is also the reason for eukaryotes to be slower in the process of synthesizing mRNA because they don't have organelles to process it faster. Finally, because they don't have a nucleus to help them assimilate the mRNA.

Select the correct answer.
Lena [83]
The correct answer is D, white blood cells.
We know that red blood cells deliver nutrients and are not apart of the immune system; platelets are responsible for coagulation, which has nothing to do with the immune system, and plasma is a substance that, again, has nothing to do with immunity. White blood cells are the only things that fight disease (antibodies are white blood cells)!

I hope I helped!

Drag and drop a term to match these examples with the correct level of organization. Organ Organ system Tissue
sineoko [7]

Answer:

This question is incomplete as the term to match with the level of organisation is not included, the terms are;

circulatory system

cardiac muscle

heart

human body

The ANSWER is:

Organ = heart

Organ system = circulatory system

Tissue: cardiac muscle

Explanation:

The level of organization of multicellular organisms is made up of cell, tissue, organ, organ system and eventually organism.

- The tissue is composed of several cell, which are basic units of any living organism. Cells that perform similar function come together to form the tissue. Example is the CARDIAC MUSCLE in this question, which is a muscular tissue made up of cells called myocardiocytes.

- Organs are structures formed as a result of collection of tissues with similar function. For example, the HEART is a circulatory organ made up of cardiac tissues, connective tissues etc.

- Organ systems is made up of organs that perform the same function in a living organism. In the case of the CIRCULATORY SYSTEM, it is made up of organs such as heart, blood vessels, lungs etc.
