What role does differential reproduction play in natural selection?

The correct answer is option A, that is, some organisms have different reproductive success because of nongenetic traits.  

The phenomenon in which some members of the population reproduce more offspring in comparison to the other is known as differential reproduction. This takes place because of the differences in the phenotypic features found in some members but not in others. This favors their survival and provides them with the chance to reproduce.  

This can be illustrated by the color variation in the beetle populations. The brown beetles were identified and determined by the population of crow, while the green beetles were not detected easily by the crows, as they are living on grass, which is similar to their own color. Thus, the green color being a phenotypic nongenetic feature and provided a survival advantage to them over the brown beetles, and thus, such beetles will also get the chance to reproduce and grow in number.

Organisms exhibit different types of adaptations as a means of survival. What type of adaptations do the caterpillar and the pla
Serjik [45]

Answer:

The type of adaptations exhibited by both organisms depends the effects each exhibited on the other.

When natural selection acts on the variation passed from generations to generations in a population,the organism involved are best fitted to survive in their habitats.The Ability of species of organisms to be best fitted against the selective pressure,so that it is naturally selected in the population is called adaptation.It is one of the driving force of evolution.

in this scenario the caterpillar,is camouflage by its green color,which blend with that of the leaves.And therefore ensure the escape from the predators e,g birds,spiders,reptiles This is an example of structural adaptation.Since it is the structural characteristics of the caterpillar that adapted it to its environment.

Likewise in the case of the plants,despite harbouring the caterpillar it ensures it does not destroy it physiological make up,by releasing chemical substances to  keep away the organisms.This is called physiological adaptation,because certain biochemical substances are diffused by the plants in response to the caterpillar (stimulus), to keep off the organisms  away,to ensure the survival of the leaves.Since physiology is the study of function of an organisms,changes in biochemical and cellular reactions must be responsible for the biochemical substances produced.

Which of the following correctly describes a reaction that forms a disaccharide from two monosaccharides?
mihalych1998 [28]

Answer: Option B) Glucose + fructose → sucrose

Explanation:

Sucrose, with formula C12H22O11, is a dissacharide (carbohydrates composed of two simple sugars) with glucose and fructose units linked by glycosidic linkage. The glucose and fructose are referred to as monosaccharides.

Thus, the two monosaccharides (glucose and fructose) forms sucrose

9. You find a rock 7,500 km away from the nearest seafloor spreading center. The plate is spreading at 5 cm/year, how old is the
Anna [14]
The answer is 150,000,000 years (150 million years)

Let's first convert 7,500 km to cm:
1 km = 100,000 cm
7,500 km = 7,500 · 1 km = 7,500 · 100,000 cm = 750,000,000 cm

Now, it is known that the plate is spreading at 5 cm per 1 year. Make a proportion:
5 cm : 1 year = 750,000,000 cm : x
x = 750,000,000 cm · 1 year ÷ 5 cm = 150,000,000 years

In an experiment, 1000 rodents were released into a light brown sandy area where no rodents previously existed. The rodents’ fur
Novosadov [1.4K]

Answer:

C) Rodents with black fur color will decrease in frequency as they are more visible to the predator against the light sand background.

Explanation:

As we know that the area that the rodents were released has a light color and a rodent predator, we can conclude that the black-colored rodents will be the ones that will be most captured by the predator and will decrease its frequency. This will happen because the brown and tan rodents are more similar to the color of the place and therefore will be able to stay camouflaged, making it difficult for the predator to see them, this does not happen with the black rodent that will be easily seen and captured.

Select the correct answer.

Answer:

C. when a portion of the moon passes through the earth's umbral shadow.

Explanation:

A partial lunar eclipse occurs when the Earth passes between the sun and moon but the celestial bodies are not arranged in a straight line. When that occurs, a small part of the moon's surface is covered by the darkest, central part of the shadow of the Earth called the umbra. The rest is covered by the outer part of the shadow, termed penumbra.
