Why don't cells continue to grow as an organism grows larger

Vlada [557]3 years ago

Body cells don't live long. They only live a couple of weeks or months. The only thing is that white blood cells live a lot longer than red blood cells. They don't grow larger because cells are microscopic. They have to be able to fit through arteries and veins in the body. There must be enough to supply oxygen towards the organs in the body. Cells are made in the bone marrow and are produced in the same size. Unless you have a disease like sickle cell anemia, your cells are round, small, and microscopic.

Tom [10]

Answer:

oxygen

Explanation:

A limiting factor is any condition whose decrease, increase, absence or presence is able to limit/stop population growth. Examples of limiting factors include abiotic conditions (e.g., temperature, water, oxygen, CO2, etc) or biotic conditions (e.g., food, mate, etc). There are many aquatic species that require high levels of oxygen (e.g., fish), thus being it a limiting factor for these species.

This part is used to bring the specimen into sharp focus. This part causes a very small up and down motion when used.
Mekhanik [1.2K]

Answer:

Fine focus.

Explanation:

If you're referencing a microscope, then it would be fine focus. Coarse focus is a basic focus used to properly see a specimen, while fine focus enhance clarity and precision. To use both, you have to gently twist a knob until you can see the specimen at a desired clarity.

Here's a reference image if you need it, it's labeled all the parts of a microscope.

First identify the gametes. use pink labels to identify the male and female gamete types and white labels to identify the gamete
Lady bird [3.3K]
I found the whole exercise on the internet. Attached is the scheme with labels for the gametes, f2 generation, and respective frequencies.

For the gametes position, on the left pink square on the male gametes side you should put a capital G, <span>and on the right pink square on the male gametes side you should put a small g, as</span> the only two possible offsprings that are showing is "GG" under the left male gamete and "gg" under the right male gamete. On the top pink square on the female gametes side you should put a capital G, and on the bottom pink square on the female gametes side you should put a small g, as the only two possible offsprings that are showing is "GG" on the same line as the top female gamete and "gg" on the same line as the bottom female gamete.
As for the frequencies of the gametes, you should put the white label that marks 1/2 by the side of each gamete.
Related to the F2 generation, the top right and bottom left pink squares should have the label with a capital G and small g - "Gg" which reflects the combination of the male gamete on its line with the female gamete also on its line.
As for the frequencies of the progeny, each of the genotypes formed from the union of the gametes should have by the side the white label that marks 1/4.
The totals would be that GG is 1/4, Gg is 1/2 (1/4+1/4), and gg is also 1/4.
