Why did the peppered moth population change from mostly dark to mostly light from the 1950's to the 1990's?​

Answers

Answer 1
When the environment changed, due to pollution, the moth population shifted because light-colored moths became easier to see so they were eaten more often. Organisms that survive have a better chance of reproducing so the population continues to grow.

2/Ecological deficit

3/Economic reserve

4/Ecological reserve

Answers

Answer: 4/Ecological reserve

Explanation:

Ecological reserves are those places which maintain a natural balance of abiotic and biotic resources. Examples are forests, wild life sanctuaries, national parks, and others. These are rich source of biodiversity as these areas are restricted to be affected by the human population. Also the large number and diversity of vegetation is capable of absorbing carbon dioxide, carbon monoxide which is a chief pollutant gas released from automobiles, household chimneys, and industrial gaseous discharge.

Thus Canada forests are ecological reserves which absorbs the pollution from different sources thus they purify the air.

Why is the land breeze experienced at night?
need an explanation related to the following diagram

Answers

Land breezes usually occur at night because during the day the sun will heat land surfaces, but only to a depth of a few inches. ... The movement of the wind is a result of differences in air pressure over the land and the ocean. Warm air is less dense and rises, therefore cool air is more dense and sinks. At night, the roles reverse. The air over the ocean is now warmer than the air over the land. ... This causes a small temperature gradient between the ocean surface and the nearby land at night and the wind will blow from the land to the ocean creating the land breeze.

What does the parable of the lost sheep explain? Use complete sentences.
Help fast I will give Brainlyest so please help

Answers

Answer:

In a religious standpoint, the parable of the lost sheep, which comes from the Holy Bible, essentially states that Jesus (the shepherd in the story), would go out of his way to find the sinners (the lost sheep), and bring them back to God. It can also be taken in the context that the lost sheep are those who do not believe, and that the shepherd would go and 'save' them, or convert them to Christianity. Essentially, it is God's promise to go out to save those who stray from the path.
