In prokaryotes, the processes of transcription and translation are said to be coupled, which means that: the primary transcript is immediately converted into mRNA. they are connected in space and time. the primary transcript is the mRNA. the primary transcripts carry the genetic information for the synthesis of several different proteins. several ribosomes bind to the same primary transcript.
Answer:
The correct answer is ''they are connected in space and time.''
Explanation:
Transcription consists of the copying of 1 DNA chain to give an RNA chain, thanks to the complementarity of bases. The strand that is copied is known as the template strand or the transcribed strand. This chain will obviously be complementary to the RNA. A transcription unit is known as that DNA that gives rise to an RNA molecule through the transcription process. For transcription, the presence of RNA polymerase is essential, since this enzyme is in charge of synthesizing RNA, thanks to its complementarity with the template chain. RNA polymerase initiates transcription when it binds to the promoter. Transcription and translation in prokaryotes are simultaneous and from a single gene many copies of RNA can be transcribed simultaneously, which are simultaneously translated, unlike in eukaryotes where the nuclear membrane separates transcription and translation in space and time.

The female reproductive system includes the glands and organs that produce the female gamete, the egg. The highlighted part in the diagram stores eggs. Thus, option C is correct.
What are the parts of the female reproductive system?The female reproductive system has various organs like ovaries, fallopian tubes, vagina, uterus, accessory, and other external organs. They are involved in the production and storage of eggs or the ovum.
The ovaries are the main organs that are two in number and oval-shaped structures, located on either side of the uterus, and produce ovum and hormones, estrogen and progesterone.
During the menstrual cycle, one of the ovaries releases the ovum in the fallopian tubes that may get fertilized or get shaded with the blood and tissues. The egg is produced through the process of oogenesis in the ovaries.
Therefore, the highlighted part is the ovary that stores the egg.

A researcher studying handwashing uses guidelines set by the American Society of Microbiology to determine if handwashing has taken place: use warm or hot running water and soap while washing for 10 to 15 seconds all surfaces, including wrists, palms, backs of hands, and under fingernails. This guideline is considered a. the Hawthorne effect. b. an operational definition. c. a correlation. d. a test.
Answer:
The correct answer is b. an operational definition.
Explanation:
An operational definition constitutes the set of procedures that describe the activities that an observer must carry out to receive sensory impressions, which indicate the existence of a theoretical concept to a greater or lesser degree. In this sense, it tries to clearly indicate how the variables are going to be manipulated or measured and also indicates that to measure a variable, it is necessary to carry out a series of activities or procedures. It is the one that builds or adapts from others, based on the observable characteristics of the phenomenon; indicating the concrete, empirical elements or indicators of the fact to be investigated.

Why does a fever become dangerous to body functions if it continues to rise?
A. Dehydration will occur
B. Osmosis may be affected due to lack of water
C. A fever breaking is more dangerous than the fever itself
D. Proteins become denatured and are unable to complete their jobs
b osmosis may be affected due to lack of water
Fever has been defined as the rise in the temperature of the body. The rise in fever is a dangerous process as lack of water causes dehydration in the body. Thus, option A is correct.
What is dehydration?Dehydration is the loss of water and body fluid than the intake of the fluid amount. The high-temperature condition of the body causes the loss of water from the body that gets evaporated from the skin cells.
When a person is suffering from fever the body fluid and electrolytes are lost by vomiting, tears, sweat, diarrhea, and urine. Dehydration can be detected by thirst, dry mouth, dizziness, etc.
Too much heat in the body during fevers results in the loss of water from the body that is more because the fluid intake gets reduced and the body becomes deficient in electrolytes and fluids.
It is a serious problem that should be dealt with so that the cells and tissues of the body can restore the water balance that is crucial for various activities and functions.
Therefore, option A. increase in the temperature in fever causes dehydration.

Consider one such cell where the magnitude of the potential difference is 40 mV, and the inner surface of the membrane is at a higher potential than the outer surface. A sodium ion (Na ) is initially just outside the cell membrane (initially at rest). How much work (in J) is required for a cell to absorb the ion, so that it moves from the exterior of the cell to the interior
Answer: W = 6.4x10⁻²¹J
Explanation: Work is the energy transferred to or from an object due to the application of a force along a displacement.
The ion Na is gaining energy to move from a lower potential to a higher one.
For this to happen, the work done is calculated as
[tex]W=q.\Delta V[/tex]
in which
W is work in Joules (J)
q is charge in Coulomb (C)
[tex]\Delta V[/tex] is potential difference in Volts (V)
The ion Na has one positive charge. In coulombs, the charge is
q = 1.6x10⁻¹⁹C
The potential difference in Volts is
[tex]\Delta V[/tex] = 40x10⁻³ or 4x10⁻²V
Calculating
[tex]W=q.\Delta V[/tex]
W = 1.6x10⁻¹⁹. 4x10⁻²
W = 6.4 x 10⁻²¹ J
The work done to move an ion of sodium from the exterior to the interior is 6.4 x 10⁻²¹ J.

Answer:
To absorb water to lowers the intensity of flood.
Explanation:
The main role of certain plant cells in flood control is to absorb water as well as the decrease the flow of water which slower down the intensity of flood. There are some plants in which their cells absorb huge amount of water which decreases the amount of water in the flood and as a result flood water decreases so that's why vegetation is very important in order to avoid flooded condition.

Answer:
RR is hom0zygous dominant and will Red
Rr is heterosygous and will also be red
rr is hom0zygous recessive and will be white
Explanation:
The filling of the chart with respect to the genotype given is as follows:
RR (homozygous dominant) gives Red eye color in fruit flies. Rr (heterozygous) will also deliver red eye color in fruit flies.rr (homozygous recessive) gives white eye color in fruit flies. What is meant by Genotype?Genotype may be defined as the ultimate combination of alleles of those genes which are selected for specific study in order to deliver some sort of genetic information.
As it is an organism is its complete set of genetic material. These can also be utilized in order to refer to the alleles or variants an individual carries in a particular gene or genetic location.
In fruit flies, red eye color is dominant over white eye color. So, when red eyed-colored (RR) flies are crossed with white-eyed colored flies (rr), they produce offspring with the genotype Rr and phenotype of red-eye color. This all deals with the law of dominance.
Therefore, the filling of the chart with respect to the genotype given is well described above.
