It is possible for a repressor to negatively regulate the expression of an operon because: A. the repressor-binding site overlaps the promoter site of the operon, allowing it to physically block the binding of RNA polymerase. B. the repressor induces the expression of the inducer by binding to the promoter that comes before the inducer gene. C. the repressor-binding site on the DNA overlaps with the translation start site, thereby preventing the transcription.

Track the evolutionary path of a butterfly and comment on it.

Answers

Answer:

The colorful canvas of the butterfly wing is an example of evolutionary innovation and adaptation. Compared with their ansestors, whose wings wore patterns of black, brown, and gray, the Lepidoptera (butterflies and moths) evolved a more varied palette of pigmentation.

I think it is very cool that they were able to evolve. For example, some butterflies use their bright colors to trick preators into thinking they are poisonous. The early butterflies could not do this.

Explanation:

Please brainliest!

Based on scientific information, the evolutionary path of a butterfly is primarily based on the origin of its species to eukaryotes and then to bilateria.

What is an evolution?

An evolution refers to a biological and physical process that involves a gradual change in the characteristics and genetic make-up of the various species of organisms over several generations.

Based on scientific information, the evolutionary path of a butterfly is primarily based on the origin of its species to eukaryotes and then to bilateria such as:

Mid Eocene epochMid-CretaceousMoth

Butterfly is a species of living organism with various characteristics and genetic make-up that have been in existence for about 60 million years.

Compare and contrast negative and positive feedback loops. Which one is more common? Why?

Answers

Answer:

Negative Feedback LoopsA negative feedback mechanism or loop is a pathway stimulated by the deviation in the output, which causes changes in output to the direction opposite to the initial deviation.The negative feedback mechanism moves the variable factors towards the stable state or homeostasis after the control unit interprets the extent of the deviation.Negative feedback loops are more common than positive ones as they tend to stabilize the system.The loop detects the change in output and acts in the opposite direction to nullify the stimulus causing the change.These loops are activated under two conditions; when the value of the variable is above the normal value and has to be brought down and when the value of the variable is below the normal values and has to be brought up.Negative feedback mechanisms occur as a part of homeostasis to bring the variables back to their normal levels by counteracting the stimulus, causing the deviation in the first place.Like in a positive feedback mechanism, a negative feedback mechanism also contains different components that together help to maintain a stable state.

Examples of Negative Feedback Mechanism

1. Regulation of blood glucose level

2. Temperature regulation

Positive Feedback LoopA positive feedback mechanism, as the name suggests, is a pathway that in response to a deviation in the output causes the output to change even more in the direction of the initial deviation.A positive feedback mechanism amplifies the deviations and brings state changes to the output.Positive feedback mechanisms are far less common than negative feedback mechanisms as it moves the body away from homeostasis.The process of positive feedback mechanism progressively amplifies the response as long as the stimulus is continued.The positive feedback loop can consist of either a single component that activates its own activity or several components with direct and indirect interactions.Positive feedback loops in biological processes are often observed in processes that need to occur quickly and towards completion as the output tends to increase the effect of the stimulus.Positive mechanisms are very few within living systems like the human body, but these can also be observed in the ecosystem, like in the case of ripening of fruit.

Examples of Positive Feedback Mechanism

1. Menstrual cycle

2. Childbirth

Negative feedback loops are more common than positive ones as they tend to stabilize the system.

Positive Feedback vs Negative Feedback (8 Key Differences)

Definition

The positive feedback mechanism is a pathway that in response to a deviation in the output causes the output to change even more in the direction of the initial deviation. A negative feedback mechanism or loop is a pathway stimulated by the deviation in the output, which causes changes in output to the direction opposite to the initial deviation.

Effect on the homeostasis

A positive feedback mechanism breaks down the homeostasis system of the body. A negative feedback mechanism works to maintain the conditions of homeostasis in the body.

Occurrence

The positive feedback mechanism is less common and occurs in specific situations.The negative feedback mechanism is more common and occurs in different organs and systems in the body.

Stability

The positive feedback mechanism is less stable.The negative feedback mechanism is more stable.

Effect

In a system with a positive feedback mechanism, the effective input is increased by the addition of actual input with the feedback signal.In a system with a negative feedback mechanism, the effective input is decreased as the feedback signal inhibits the actual input.

External interruption

A positive feedback mechanism might require an external interruption.A negative feedback mechanism doesn’t require an external interruption.

Changes

Positive loops enhances the change in physiological factors.Negative loops resists changes in physiological factors.

Examples

Positive feedback mechanism in nature is observed during childbirth in humans and during the ripening of fruits. The negative feedback mechanism is observed during thermoregulation and maintaining the blood glucose level.

NASA scientists use satellites to monitor two important factors that lead too landslides

Answers

Answer:

The most important factors that lead to landslides are the declivity of the terrain and the type of soil.

Explanation:

Stony soils are more prone to landslides, especially on steep terrain and without any type of vegetation cover. During heavy rainfall, these two factors can promote landslides that cause major disasters, as water is able to drag this soil violently. To prevent this from happening and people from being harmed, NASA has developed satellites, which capture rainfall data and monitor the slope and composition of soils, being able to see in advance areas that could be landslides. In this way, it is possible to develop strategies that prevent the landslide from happening.

C The population expands its territory into new habitats.

D The population size decrease due to competition.

Answers

Answer:

B

Explanation:

The population size increases

A population of squirrels eats acorns from local oak trees. In some years, oak trees produce much greater numbers of acorns than usual. The most direct effect of an increase in acorns on the squirrel population would be: the population size would increase, which is option B.

When there is an abundance of acorns, the squirrel population can benefit from a readily available food source. With more food available, squirrels are better able to meet their nutritional needs and reproduce successfully. This leads to an increase in the population size as more squirrels are born and survive due to the abundance of resources.

Q) In three to five sentences, construct an argument for the claim that natural selection leads to evolution. Provide evidence for this claim, and be sure to explain how an organism shows the four parts of the process of natural selection. You may use any organism with the exception of bacteria and antibiotic resistance.

Answers

Answer:

Natural selection leads to evolution due to the way reproduction works. In the example of European moths during the industrial revolution, we can see this clearly. When the industrial revolution was going, there was more pollution, hence darkening the skies and leaving ash. Moths, which before were white with occasional black spots dominated the area until pollution effected their environment. Whiter moths were eaten by bird who could easily see them against the black trees and skies. These moths could no longer reproduce, they were dead. Moths with more black could survive longer to reproduce because they were harder to see. As time went along, the moths turned mostly black, showing an example of evolution.

This method  of natural selectionthat the fantastic alleles of this variation organism are surpassed directly to offspring, the system of  natural selection results in evolution occurring.

What is natural selection?

Natural selection is the system thru which populations of residing organisms adapt and extrade. Individuals in a populace are evidently variable, which means that they're all one of a kind in a few ways.

Natural selection is a mechanism of evolution as there are. Evidence for evolution: anatomy, molecular biology, biogeography, fossils, & direct observation.

variation in a population exists

Explanation:

Variation is present in a population of antelopes so due to this variation, the predator such as lion can catch the slowest antelope that is present in the population while on the other hand, the faster antelopes can save their lives by running very fast. Variation is present in a population of antelopes due to availability of food as well as genetic characteristics. These variation leads to the availability of food to the lions.

Know how to calculate the amount of chromosomes in mitotic cells and in gamete cells, when given an amount of the chromosome number for one of the two types of cells. For example, a fruit fly has 8 chromosomes or 4 pairs of chromosomes in its wing cells, how many chromosomes will be in each egg cell?

Answers

Answer:

4 chromosomes

Explanation:

Meiosis is a kind of cell division that produces daughter cells that already have their chromosome number reduced by half. Due to this reason, meiosis is called a reduction division. A diploid parent cell (2n) will produce gametes with haploid cells (n).

According to this question, a fruit fly has 8 chromosomes or 4 pairs of chromosomes in its wing cells, after undergoing meiotic division, it will possess 4 chromosomes in each gamete cell. Note that the chromosome number has been reduced by half.
