Answer:

While sunlight is the energy source, the greatest force propelling the water cycle is gravity. Gravity is the force of attraction between two objects, and Earth's gravity pulls matter downward, toward its center. It pulls precipitation down from clouds and pulls water downhill. Gravity also moves air and ocean water.

Dovator [93]

Answer:

Explanation:

The cell cycle is divided into 2 main phases namely:

The interphase
The m phase

While the m phase is the active division phase, the interphase is further divided into:

G0 phase which is essentially a resting or quiescence phase for cells that do not need to divide ordinarily.
G1 phase which is characterized by growth and development of the cell.
S phase which is a phase during which DNA is synthesized
G2 phase during which protein is synthesized.

<em>Hence, if a cell is noticed to have half as much DNA as the surrounding cells, it means that particular cell's cell cycle halted at G1. The cell has not been able to synthesize DNA unlike the surround cells.</em>

storchak [24]

Answer:

Nucleus contain 8 picograms of DNA at Synthesis phase or S phase

Explanation:

Synthesis phase or S phase is an important phase occuring in the Interphase of the cell cycle.

S phase deals with replication of DNA resulting in the formation of two daughter DNA molecules from a single DNA molecule.As a result the amount genetic material or DNA is being doubled in the synthesis phase or S phase.

From that point of view it can be stated that the nucleus will contain 8 picograms of DNA in the S phase or Synthesis phase.

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.

What is the function of the hair follicle

kaheart [24]

Answer:

A hair follicle anchors each hair into the skin.

Explanation:

The hair bulb forms the base of the hair follicle. In the hair bulb, living cells divide and grow to build the hair shaft. Blood vessels nourish the cells in the hair bulb, and deliver hormones that modify hair growth and structure at different times of life.
