Answer:

QUESTION:

Where do most transform boundaries occur?

ANSWER:

Transform Plate Boundaries are locations where two plates slide past one another. The fracture zone that forms a transform plate boundary is known as a transform fault. Most transform faults are found in the ocean basin and connect offsets in the mid-ocean ridges.

Answers

Answer:

A) asexual reproduction

Explanation:

Mitosis plays an important part in the life cycle of most living things, though to varying extents. In unicellular organisms such as bacteria, mitosis is a type of asexual reproduction, making identical copies of a single cell. In multicellular organisms, mitosis produces more cells for growth and repair.

A particular species of bacteria has a "a generation time" of 20 minutes. That is, every 20 minutes a single bacterium completes prokaryotic fission -- one bacterium is now two bacterial cells. This morning at 6:00 a.m. you made a sandwich and packed your lunchbox. What you were not aware of was that there were 10 bacteria cells of this species on the dollop of mayonnaise that you spread across your bread. At 12:00 p.m. (no on) You sit down and eat your entire sandwich! How many bacteria cells did you have for lunch? (Hint: use the formula 2axb x C = numbers of cells, where "a" - number of times per hour the bacteria reproduces, "5" the number of hours the bacteria had to reproduce, and "C" = the number of bacteria at the start).​

Answers

Answer:

Number of bacteria cells = 2621440 cells

Explanation:

The generation time of a bacteria specie is the time it takes for a population of bacteria to double in number. The generation time for most common bacteria is quite short, about 20 minutes to 1 hour.

Bacteria reproduce asexually by binary fission, in which the parent cell divides into two to produce two identical daughter cells.

In the given question, the generation time of the bacterial species is 20 minutes.

The time that have passed from between the time the sandwich was packed at 6:00 am to lunch time by 12:00 pm is 6 hours.

Using the given formula in the hint: number of cells = 2^(ab) × C

Where a = number of times per hour the bacteria reproduces; b = number of hours; C = number of bacteria at the start

a = 60 minutes/ 20 minutes = 3; b = 6; C = 10

Number of cells = 2^(3 × 6) × 10

Number of cells = 2621440 cells

The technology time for the maximum not unusual place bacteria is pretty short, approximately 20 mins to one hour. The number of bacteria cells did have for lunch =2621440 cells.

Bacteria reproduce via way of means of binary fission, wherein the discern molecular divides into a time of the bacterial species is 20 mins.The time which has handed from among the time the sandwich became packed at 6:00 am to lunchtime via way of means of 12:00 pm is 6 hours.Using the given formulation withinside the hint: range of cells =2^  (ab)×C.Where a = range of instances in step with hour the reproduces; b = nu of hours; C = number of bacteria on the start.a = 60 mins/ 20 mins  = 3; b = 6; C =10.The number of bacteria cells did have for lunch =2621440 cells.

What is bacterial cel?

Bacterial cells are exceptional from plant and animal cells. Bacteria are prokaryotes, because of this that they haven't any nucleus. A bacterial includes Capsule.

Thus it is clearly explained above that the number of bacteria cells did have for lunch =2621440 cells.

Rabbits in most areas have a brown coat. The arctic hare has a bright white coat in
winter. How does the arctic hare's white color help it survive?

Answers

Answer:

Indeed, rabbits, in most of the planet, tend to have their fur colored brown, copper or other similar shades. Now, in the Arctic regions, these animals do not have this color, but a white one, similar to the environment that surrounds them. This is so because these animals, for evolutionary reasons, have adapted their fur to the snowy environment that surrounds them in the Arctic, in order to avoid being detected by potential predators, protecting themselves and trying to ensure their survival.

At the end of Meiosis II, each daughter cell has 23 single-stranded chromosomes.
True
OR
False

Answers

Answer:

y the end of meiosis, the resulting reproductive cells, or gametes, each have 23 genetically unique chromosomes. ... Each daughter cell is haploid, because it has half the number of chromosomes as the original parent cell.

Explanation:  

30 chromosomes

Each daughter cell will have 30 chromosomes. At the end of meiosis II, each cell (i.e., gamete) would have half the original number of chromosomes, that is, 15 chromosomes. 2.

From a diploid germ cell 2n =24 double stranded chromosomes, meiosis will produce four gamete haploid cells n =12 single stranded chromosomes.

Meiosis produces four with half because double stranded chromosomes represents DNA replication. Twice as much DNA as a diploid cell needs.

From a diploid germ cell 2n =24 double stranded chromosomes, mitosis will produce two diploid daughter cells 2n =24 single stranded chromosomes for the same reason.

DNA replication doubles the genome before cell division. Sister chromatids of double stranded chromosomes represent the replicated DNA. During cell division, sister chromatids of double stranded chromosomes are separated into different cells.

Meiosis has two stages, the first separating homologous pairs of double stranded chromosomes, and then the second stage separating sister chromatids into four haploid (n) gametes.

What is the correct equation for the breakdown of ozone? please answer quick

Answers

Answer:    This electricity converts the oxygen molecule to ozone. Our equation is as follows: 3O2 + energy = 2O3.

The correct equation for the breakdown of ozone can typically occur in a series of two steps known as the destruction of ozone. It is illustrated thus;

Cl + O3 ⇒ ClO + O2ClO + O ⇒ Cl + O2

The net reaction of the above process is the reaction of an oxygen atom with an ozone particle to form two molecules of oxygen.

The catalyst in this reaction is chlorine because it undergoes changes as the process continues while ozone is removed in the process. In the presence of sunlight, atomic oxygen is formed.

This entire process is referred to as the destruction of ozone.

The antibiotic rifampicin blocks transcription in many bacteria. In the presence of the antibiotic, adding sigma factor has no stimulating effect on RNA synthesis. A footprinting experiment on a rifamycin treated sample shows that the polymerase remains located at the promoter site in the presence of eNTPs and Mg2 ion. What step of transcription is rifamycin likely to block

Answers

Answer:

transcription initiation

Explanation:

Transcription is a process by which genetic information from DNA is used to synthesize an RNA molecule, usually, a messenger RNA (mRNA), which is subsequently utilized to synthesize a protein by a process called translation. Transcription in prokaryotes has three steps:

1-Initiation: the RNA polymerase is a multisubunit enzyme (holoenzyme) composed of two α, one β, one β’ and one ω and σ subunits (α2ββ’ωσ). This holoenzyme binds to the promoter region of the template DNA strand.

2-Elongation. The sigma σ factor of the holoenzyme is released and the complex and the core enzyme (α2 ββω) moves along the template strand, thereby producing an mRNA sequence

3-Termination. This step can be Rho-dependent, where a protein named "Rho" recognizes the termination site and stop transcription, and Rho-independent (transcription continues until the termination sequence is reached).

In consequence, Rifamycin is likely to block the initiation of transcription because the core RNA enzyme needs to bind the sigma factor (σ) for initiation of transcription in bacteria.
