What was the genetic variation of dark moths and how did it occur?

Answers

Answer 1

Answer:

Natural Selection

Explanation:

A random genetic mutation gave rise to the dark colored moths. All types of living things have small differences between the individuals in the species. If one of those differences allows the individual to live longer, they will likely have more offspring. As that trait is passed on, the population starts to look more like a successful individual. Over time, the species changes.

Substance A's molecules are small. Substance B's molecules, which react with substance A to produce a blue-black color, are larger in comparison. If a solution of substance A is placed inside a selectively permeable bag, and the bag is placed in a solution of substance B, what will happen?

Answers

Here's link to the answer:

tinyurl.com/wpazsebu

When A reacts with B, it turns blue-black because the substance A is starch and its molecules are small, which is glucose. The substance B is iodine, which combines with starch to become blue black. If A is present in B, then the A will become blue black.

What is the reaction between the starch and the iodine?

Starch is a polymer that is made up of glucose monomer and is found in plant-based food products. This starch can react with iodine and produce a blue-black coloration, so when the substance A is placed in the substance B with a selectively permeable membrane, the substance B (iodine) can easily enter the starch and form the blue-black coloration. This is known as the starch-iodine reaction, and it results in a blue-black polysaccharide.

Hence, if a solution of substance A is placed inside a selectively permeable bag and the bag is placed in a solution of substance B, then the substance A (starch) will turn blue-black.

Answers

This type of plant tissue you’re talking about is Vascular

Vascular tissue contains open vessels that transport water, ions, minerals, and nutrients throughout a plant.

Vascular plant tissues in higher plants can be divided into phloem and xylem.

These tissues (vascular) are fundamental to transport water and solutes to all tissues of a plant.

Conversely, meristematic tissue is a type of tissue composed of undifferentiated cells.

In conclusion, vascular tissue contains open vessels that transport water, ions, minerals, and nutrients throughout a plant.

Pls HELP

Answers

The correct answer should be soil erosion if I’m not mistaken

Soil erosion may be caused by an interaction between the hydrosphere and geosphere.

What do you mean by soil erosion?

Soil erosion is the denudation or wearing away of the upper layer of soil. It is a form of soil degradation. This natural process is caused by the dynamic activity of erosive agents, that is, water, ice, snow, air, plants, and animals.

Soil erosion occurs primarily when dirt is left exposed to strong winds, hard rains, and flowing water. In some cases, human activities, especially farming and land clearing, leave soil vulnerable to erosion.

The effects of soil erosion go beyond the loss of fertile land. It has led to increased pollution and sedimentation in streams and rivers, clogging these waterways and causing declines in fish and other species.
