Which graph represents selection that may lead to reduced variation in a population?

Which Graph Represents Selection That May Lead To Reduced Variation In A Population?

Answers

Answer 1

Answer:

The first graph

Explanation:

I think it's the first graph because the first graph is not very different from the population after selection and the original graph in the first one seemed to have shifted towards the right, quite possibly indicating an increase in population.

The second graph has an apparent change in comparision to the original function.

Hope this helps!! good luck btw

The amplitude of a seismic wave generally decreases as the wave moves away from the epicenter because the waves encounter entirely different media.

Option D. The waves encounter entirely different mediums.

What are seismic waves and epicenter?

Seismic waves are waves of a mechanical nature, they propagate on Earth as a result of an earthquake or explosion. They are vibrations that are transmitted due to a release of energy from a specific point that is called a seismic focus. and the resistance found in the medium in which it propagates decreases the energy, dicipating it.

With this information, we can conclude that Seismic waves are movements of rock particles that are transmitted along concentric surfaces due to the sudden release of energy at the seismic focus.

trace a molecule of glucose from the renal artery to the renal vein.

Answers

a. Glucose in the renal artery follows a pathway through various renal structures before reaching the renal vein.

b. Urea in the renal artery is filtered, reabsorbed, and secreted through the renal tubules before being eliminated outside the body.

a. The glucose molecule from the renal artery will move forward through the following pathway:

Renal artery → Segmental artery → Interlobar artery → Arcuate artery → Interlobular artery → Afferent arteriole → Glomerulus → Glomerular filtration → Proximal convoluted tubule → Loop of Henle → Distal convoluted tubule → Collecting duct → Renal vein.

In the glomerulus, glucose will be filtered from the blood into the renal tubules. It will then undergo reabsorption in the proximal convoluted tubule to be transported back into the bloodstream. As it progresses through the renal tubules, glucose will undergo various processes of filtration, reabsorption, and secretion until it reaches the collecting duct, where it will eventually be carried by the renal vein back into circulation.

b. Urea, a waste product formed in the liver, follows this path from the renal artery to its final destination outside the body:

Renal artery → Glomerulus → Glomerular filtration → Proximal convoluted tubule → Loop of Henle → Distal convoluted tubule → Collecting duct → Renal pelvis → Ureter → Urinary bladder → Urethra.

In the glomerulus, urea is filtered out of the blood and enters the renal tubules. It then undergoes reabsorption and secretion processes as it travels through the renal tubules, eventually reaching the collecting duct. From there, urea flows into the renal pelvis, enters the ureter, and continues into the urinary bladder. Finally, it is expelled from the body through the urethra during urination.

Duchenne muscular dystrophy is caused by a mutation in a gene that comprises 2.5 million base pairs and specifies a protein called dystrophin. However, less than 1% of the gene actually encodes the amino acids in the dystrophin protein. On the basis of what you now know about gene structure and RNA processing in eukaryotic cells, provide a possible explanation for why less than 1% of the gene encodes the dystrophin protein. A. It is likely that the 5′ cap serves as an indicator for a smaller region of the gene to be used for translation of the protein.
B. It is likely that during the splicing process, a majority of the pre‑mRNA is removed in an effort to splice out all the introns.
C. It is likely that the addition of the 5′ cap contributes to the majority of the mRNA degrading, preventing its ability to be used for protein production.
D. It is likely that during the splicing process, a majority of the pre‑mRNA is removed in an effort to splice out all the exons.

Answers

From these data, less than 1% of the genes encode the dystrophin protein because it appears that the 5′ cap serves as an indicator for a smaller region of the gene to be used for translation of the protein.

Option A seems to have the right explanation.

Dystrophin is encoded by the DMD gene. The DMD gene is a large sequence but encodes a single protein. Only less than 1% of this large sequence area is responsible for coding the actual protein. This suggests that the remaining DNA sequence of the DMD gene is occupied by too many double intron sequences spliced from the mRNA transcript before translation can occur.

The researchers found that the DMD gene contains several splice sites which are deleted from the main mRNA transcript after transcription has occurred. The actual exonic sequence in the DMD gene is too small, so the probability of a mutation occurring is very low. This is not a normal case of gene silencing as DMD has mutated lesions in which gene silencing has no effect.

Answers

It is anticipated that the outcomes would differ if the experiment had been conducted with natural gas since the reaction time would have been slower.

What is Reaction time?

This is the interval of time between a stimulus and a reaction, or the overall amount of time needed for a reaction to take place.

Natural gas produces heat more steadily and at a higher temperature, which speeds up reactions.

The objective of the scientific field of mental chronometry is to determine the content, duration, and temporal sequencing of mental operations by measuring processing speed or reaction time on cognitive tasks.

On elementary cognitive tasks (ETCs), which are very straightforward perceptual-motor tasks commonly given in a laboratory environment, reaction time (RT; also known as "response time") is measured by the amount of time that has passed between the stimulus's onset and a subject's response.

Therefore, If the experiment were done using natural gas, it is expected that the results would be different since the reaction time would be slower.

According to the Nebular Theory, the solar system began as a large, slowly rotating cloud of gas about one light-year in size. As the cloud cooled, it collapsed due to its own gravity. Conservation of angular momentum caused it to distort into a rotating pancake shape because it had to spin faster as it shrank. Then the Sun began to form at the center, and rings formed around the Sun. Next the rings coalesced into planets. Two problems with the old Nebular Theory are: (i) rings would not form around the Sun; (ii) Planets would not form because the gas pressure would be too high.

Answers

Immanuel Kant and Pierre-Simon Laplace both contributed to the growth of the Nebular Theory, an early theory that attempted to explain how the solar system formed. Although it served as a basis for comprehending how stars and planetary systems develop,

The concerns you stated were among the difficulties the theory had in attempting to explain certain elements of the development of the solar system:

(i) Rings would not form around the Sun: According to the original Nebular Theory, rings would develop around the Sun when planets formed. The study of rings around gas giants like Saturn, however, made it clear that they are not a fundamental or common element of planetary formation. It is thought that the disruption of moons or other tiny things within the planet's gravitational field causes rings to form around gas giants.

(ii) The original Nebular Theory postulated that planets originated from the coalescence of gas and dust within the revolving disc around the young Sun. However, gas pressure would be too high for planet formation. It was understood, nonetheless, that the protoplanetary disk's gas pressure would prevent the agglomeration of solid particles into bigger entities. The contemporary theory of planetesimal accretion, which describes how small solid particles progressively cluster together through collisions and gravitational attraction to become bigger things termed planetesimals, which then continue to expand to become planets, was developed to solve this issue.
