Question 7

Biology
1 answer:
babymother [125]2 years ago
8 0

Answer:

true

Explanation:

Different bacteria like to grow at different temperatures. Thus, a microbiologist will incubate a particular strain of bacteria at its optimal temperature so that he can study it when it is healthy. By changing the temperature, he can study the bacteria while they are stressed. Organisms that grow best at human body temperature, which is approximately 37 degrees Celsius (98.6 degrees Fahrenheit), are called mesophiles. Those that grow in hot temperatures between 40 to 70 degrees Celsius (104 to 158 degrees Fahrenheit) are called thermophiles. Those that grow at hot temperatures above 80 degrees Celsius are hyperthermophiles. Those that live in very cold conditions are called psychrophiles.

Describe the process of natural selection
Keith_Richards [23]
Natural selection is the process in which the more favorable traits due to mutation that are in a select few in a population produce more offspring then others. An example of this is bacteria resistant to antibiotics due to the faster reproduction of the resistant bacteria over the non resistant ones

Which of the following statements about meiosis is correct? Which of the following statements about meiosis is correct? Meiosis
Lapatulllka [165]

Answer:

The correct answer is "Meiosis produces cells that differ genetically from the parent cell".

Explanation:

In contrast with mitosis, which is the cellular differentiation that produces somatic cells; meiosis produces cells that differ genetically from the parent cell. Meiosis is a special type of cellular differentiation that reduces the genetic material by half, and results in the creation of four haploid cells that are genetically distinct from the parent cell. Meiosis allows for the maturation of sexually reproducing cells, and the genetic variations of these cells is one factor that allows for genetic variations among sexually reproducing species, such as humans.

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.
