8. What structures get duplicated during interphase I?

Mammals are adapted to live in the following environments:

ki77a [65]

Mammals are adapted to live in D - all of the above. Mammals are, infact, very versatile groups of species which have evolved in a way that also itself enables their versatility. For this reason, mammals have been able to roam the different parts of Earth and thrive in that environment.

Which letter indicates an articulating surface that is comprised of hyaline cartilage?

xxMikexx [17]

A letter indicates an articulating surface that is comprised of hyaline cartilage.

<h3>What is hyaline cartilage?</h3>

The synovial joints include hyaline cartilage, which facilitates joint motion.
Chondrocytes and extracellular matrix make up its structure.
The organization of the extracellular matrix, which determines the biomechanical characteristics of cartilage tissue, is greatly influenced by chondrocytes.
Hyaline cartilage covers the ends of the bones where they come together to create a joint.
In a typical healthy joint, this cartilage is bluish white and shiny.
Its main job is to reduce friction and act as a little cushion between the ends of the bones.

If I subtract 20 from my number, then square the result, I get the same answer as if I square my number, then subtract 20 from t

Natasha_Volkova [10]

The value of the unknown number is 10.5.

Let the unknown number = x

When 20 is subtracted from the number and the result is squared which is equal to the square of the unknown number minus 20:

(x - 20)² = x² - 20

<em>expand the equation;</em>

x² - 40x + 400 = x² - 20

<em>collect similar terms together;</em>

x² - x² - 40x = -20 - 400

-40x = -420

$x = \frac{420}{40}\\\\ x = 10.5$

Thus, the value of the unknown number is 10.5.

Escherichia coli has a doubling time of 30 minutes. If a culture has 10 E. coli cells at the beginning of log phase, how many E.

Nat2105 [25]

80 E. coli cells will be in the culture after two hours.

<h3>What is culture?</h3>

The development of the human, plant, or animal cells in a lab, as well as microorganisms like bacteria and yeast. Cell cultures can be used for research, medication testing, and infection diagnosis.

Primary (mortal) cultures and cultures of established (immortal) cell lines are the two main categories of cultures.

One of the most crucial methods in cellular and molecular biology is cell culture because it offers a platform for studying the biology, biochemistry, physiology, metabolism, and other aspects of both healthy and diseased cells.

A culture of 10 E. coli cells.

Incubation time = 2 hours = 120min

Doubling time = 30min (120/30 = 4)

So, 1 cell - 30min = 2 cells - 30min = 4 cells - 30min = 8 cells - 30min

Therefore, 8 ₓ 10 = 80cells of E. coli at the end of 2 hours of incubation time.
