A leaf-eating caterpillar turns into a nectar-eating butterfly. How is this behavior an advantage for this species?

Answers

A caterpillar that consumes leaves develops into a nectar-eating butterfly. The advantage of this behavior is that it saves it from predators and scarcity of food.

What is a caterpillar?

A caterpillar is a worm that is of different vibrant colors and invertebrates. The word caterpillar is used for the worms that are the initial stage of the insects like butterflies and moths. They eat leaves and grow large and when their life stage is completed they turn into cocoons and then the butterfly.

An insect has different life stages, like a caterpillar then cocoons, and then an insect with wings. It saves them from predators, as not everyone eats caterpillars and the butterfly form. If the leaves are not present for the caterpillar, the nectar will be present.

Thus, A leaf-eating caterpillar grows into a nectar-eating butterfly. The benefit of this habit is that it protects the animal from predators and food shortages.

What happen if amoeba spis place in sea water

Answers

Answer:

If amoeba specie placed in the sea water, it will die because sea water contains excess of salts which adversely affect the growth of amoeba.

Explanation:

Amoeba is unicellular organisms i. e. made of a single cell. They are eukaryotic organisms i. e. having true nucleus. Amoeba is found in fresh water lakes and hot spring. Amoeba is not able to live in sea water because sea water contains salt which are not good for amoeba.

Which of the following is a constructive process? abrasion
plucking
deposition
transport

Answers

DEPOSITION is a constructive process.

A constructive process refers to a process that involves the building up of a particular thing or object. Deposition refers to the geological process by which sediments are added to a land form. The sediments can be in form of soils or rocks. Weathered materials that are transported by factors such as wind, water, gravity, etc are deposited in layers leading to the building up of the land form.

This is what i found:Out of the following: abrasion, plucking, deposition, and transport, deposition is a constructive process. The process of erosion stops when the transported particles fall out of the transporting medium and settle on a surface. This is deposition.

Hope this helps! :)

Finch species living on the Galapagos Islands exhibit a variety of beak types that favor different foods. Finches that eat seeds and plant parts have beaks of the shorter, thicker variety, while finches that eat insects and other small organisms have thin, pointed beaks. 78% of the finches on an island in the Galapagos have beaks that are identical to Finch 1. What does this tell you about the availability of food for the finches on this island? A) There is an abundance of insects.
B) There is an abundance of seeds and nuts.
C) There is a wide variety of foods for the finches to eat.
D) Plants have died out and there are only insects for food.

Answers

Explanation:

B) There is an abundance of seeds and nuts.

The finches have developed adaptations to their environment. Their specialized beaks allow them to adequately exploit the available resources, by utilizing the more abundant food source.

Further Explanation:

All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly wound around histones as chromosomes. To produce daughter cells during cell division, the chromosomes (total number of chromosomes (2n)) are copied before the cell splits into two daughter cells. This process is known as mitosis, and occurs in cell division and growth processes. Two new nuclei are formed, along with identical cells. These are the same as the parent cell and the chromosome number (2n) is maintained.

Conversely in meiosis, the number of chromosomes (2n) is halved through meiotic divisions, producing 4 (n) germ cells (sperm or eggs), each containing half the number of chromosomes as its parent cell.  Crossing over, independent assortment, and random fertilization ensure genetic variation.

This variation refers to the genetic characteristics present within a species; they form new traits called alleles, which may confer adaptations that increase the fitness of a species, along with ensuring survival by conferring an advantage.

Players in any sport who are having great​ seasons, turning in performances that are much better than anyone might have​anticipated, often are pictured on the cover of Sports Illustrated.​ Frequently, their performances then falter​somewhat, leading some athletes to believe in a​ "Sports Illustrated​ jinx." Similarly, it is common for phenomenal rookies to have less stellar second​ seasons, the​ so-called "sophomore​ slump." While​ fans, athletes, and analysts have proposed many theories about what leads to such​ declines, a statistician might offer a simpler​(statistical) explanation. Explain. What would be a better explanation for the decrease in performance of the Sports Illustrated cover​ athlete? A. People on the cover are usually there for outstanding performances. Because they are so far from the​ mean, the performance in the next year is likely to be closer to the mean. B. The slope of the linear​ regression, predicting performance from years in the​ sport, must be negative because an​ athlete's performance always decreases over time. No matter how well an athlete performed one​ year, they must perform worse the next year. C. People on the cover are usually considered the best of the​year, so naturally they reached the maximum level of athletic performance that year and it is impossible to improve upon that. D. Once an athlete has made the cover of Sports​ Illustrated, they have reached their ultimate goal as an athlete and lack motivation to try the following year.
