The competitive exclusion principle tells us that two species can't have exactly the same niche in a habitat and stably coexist. That's because species with identical niches also have identical needs, which means they would compete for precisely the same resources.

Imagine yourself as a naturalist. In your travels, you observe the toad and frog
shown here. Write two questions that might arise from these observations.
Answers
Answer:
1. What is the relationship between body shape and the habitat where they are most commonly found?
2. What is the difference between toads having a thicker skin than frogs?
Explanation:
Toads and frogs are amphibians that belong to the same family, live in lakes, rivers and wetlands and have some similar characteristics. Among their main differences are:
The skin of toads is rougher, drier and rougher. While frog skin is moist and smooth. Frogs live in humid areas, although they can go out to dry land for food. Whereas toads can survive longer on the ground away from moisture, as they have greater water control in the body. Frogs are characterized by long limbs that favor long hopping and swimming. On the other hand, toads have shorter legs. Toads tend to be more rounded, muscular and stocky. Frogs tend to be more slender.Most toads are poisonous. In contrast in frogs, not all species are poisonous.
Given these observations, two questions that may arise could be:
1. What is the relationship between body shape and the habitat where they are most commonly found? This is that frogs have longer legs which helps them to swim and that is why they are more commonly found in water. While toads have shorter legs that even allow them to burrow into the ground, they can survive longer on land.
2. What is the difference between toads having a thicker skin than frogs? Toads have thicker and more impermeable skin than frogs, which allows them to live in drier places. Also, the blood of the toad is of higher osmotic concentration than water.
Answer: what is the difference between the body’s and the habitat they are in?

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.
Answers
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.

D. Transporting eggs
WILL MARK BRAINLIEST!!
Answers
Answer:
the picture isnt really clear but i guess B
Explanation:
just to explain the collecting of sperm happens in the oviduct
the developing of a fetus happens in the uterus
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.

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
Answers
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.

w, use what you have learned about heredity to complete the chart below. The allele pairs in the left column represent eye color in fruit flies. Ris the
ominant color (red), and r is the recessive color (white). Study the chart and fill in the missing phenotypes.
Answers
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.

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
Answers
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.
