The examples of natural selection are as follows:
Giraffes develop longer necks over time.A Non-poisonous snake mimics a poisonous snake.Galapagos finches choose mates with stronger and longer beaks.Peppered moths choose mates with darker colors.Thus, the correct options for this question are B, C, F, and H.
What is Natural selection?Natural selection may be defined as the methodology through which organisms that are better adapted to their environment tend to survive and reproduce more than those less adapted to their environment. The concept of Natural selection was first proposed by Charles Darwin.
According to the question, due to the requirement of long necks in order to get food from longer trees, Giraffe develops longer necks. In order to protect themselves from predators, a non-poisonous snake mimics a poisonous snake.
On Galapagos island, if there were variations in the finches of the bird, they get a variety of food resources in order to get more nutrients and energy for survival and reproduction.
Therefore, the correct options for this question are B, C, F, and H.

What is the boundary between the earths lower mantle and the upper mantle called ?
Answer:
i have trusted my best to answer
Explanation:
Edit
The upper mantle of Earth is a very thick layer of rock inside the planet, which begins just beneath the crust (at about 10 km (6.2 mi) under the oceans and about 35 km (22 mi) under the continents) and ends at the top of the lower mantle at 670 km (420 mi). Temperatures range from approximately 200 °C (392 °F) at the upper boundary with the crust to approximately 900 °C (1,650 °F) at the boundary with the lower mantle. Upper mantle material which has come up onto the surface is made up of about 55% olivine, 35% pyroxene and 5 to 10% of calcium oxide and aluminum oxide minerals such as plagioclase, spinel, or garnet, depending upon depth.

4) Discuss how our lives on Earth are directly related to our relationship and positioning with the Sun in our Solar System.
Answer:the relationship with the sun and the solar system is the same relationship to all physical bodies in which we are living at a speed governed by our perception at our vantage point in relation to how much gravity is acting upon us. Example: Say you were to fall into a black hole. At the point of no return at the event horizon your time would begin to slow down as seen from an outsider watching you fall. This will occur until to that observer sees you stop entirely in time. You however fall faster as faster but for ever. Till time is over. So all things are relative to each other in only one absolute way. Gravity control observed time.

Answer:
Death of coral reefs occurs due to increasing the temperature of the ocean.
Explanation:
Death of coral reefs occurs due to increasing the temperature of the sea and ocean because warm water killed the algae attached to the surface of coral reefs which causes bleaching of coral reefs. This coral reefs provides habitat as well as food to thousands of animals present in the ocean ecosystem so the destruction of coral reefs causes death or migration of animals from that region.
As you increase the temperature, the rate of photosynthesis increases and then decreases.

If you knew you could pass a genetic disease to your children, would you want to be allowed to use gene therapy to “fix” the gene before the children were born?
Answer:
It depends on if the gene therapy would do something to the gene that could harm you. If there is no harm to you or the children then It seems logical to do it so the children do not have the disease. Because it is a genetic disease, if you "fix" it there is a higher chance that the children will not pass it on to their kids
Explanation:
When might self-fertilization be beneficial for a plant? When there are too many dioecious individuals in a population, self-fertilization becomes beneficial for a monoecious individual. When environmental conditions are harsh, such as a plant growing in nutrient-poor conditions, or when herbivores have damaged the plant, plants may self fertilize. When environmental conditions are perfect, plants can afford to self-fertilize. Only plants with perfect flowers are capable of self-fertilization.
Answer:
Only plants with perfect flowers are capable of self-fertilization.
Explanation:
Self-pollination is the process that allows plants to fertilize themselves. This process is very beneficial when a plantation has plants with few flowers or when the plants are spaced far apart.
However, only plants with perfect flowers can self-fertilize. This is because for self-fertilization to occur, the plant needs to have flowers that present the male and female reproductive organs, which allows the same flower to produce pollen that will be sent to its own ovary. Only perfect flowers have male and female reproductive organs at the same time.

the endocrine system work together?
O A. The nervous system signals the endocrine system to release
hormones in response to a stimulus.
O B. The nervous system responds to a stimulus, and the endocrine
system returns the body to a relaxed state.
O C. The endocrine system signals the nervous system to send out
nerve impulses in response to a stimulus.
D. The endocrine system responds to a stimulus, and the nervous
system returns the body to a relaxed state.
The nervous system usually signals the endocrine system to release hormones in response to a stimulus. The correct option is A.
What is endocrine system?The endocrine system, which is made up of all of the body's different hormones, regulates all physiological processes in the body from gestation through adulthood and to old age.
This regulation also include brain and nervous system development, reproductive system growth and function, metabolism, and blood sugar level.
The endocrine system and the nervous system collaborate to influence many aspects of human behavior, together with growth, reproduction, and metabolism. And the endocrine system is crucial in the regulation of emotions.
In response to a stimulus, the nervous system basically signals the endocrine system to release hormones.
Thus, A is the correct option.
