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.

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.

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.

D Random mating

Cuz everything else leads to the way you are variated

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 examples of natural selection are as follows:

Thus, the correct options for this question are B, C, F, and H.

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.

Answer:

The relationship between Proteins and Nucleic acids is that both find their application in the gene expression process of the living body. During the gene expression in every living cell of any organism, it is seen that the nucleic acids code for amino acids to create proteins

Answer:

The nucleic acids in made up of DNA and RNA. The DNA encodes the information the cell needs to make protein, while RNA participates in protein synthesis

The nervous system usually signals the endocrine system to release hormones in response to a stimulus. The correct option is A.

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.

Answer:

ee

Explanation:

in order for the genotype to represent a recessive trait both alleles ( letters ) have to be lowercase hence the answer is ee

Answer:

45

Explanation:

Both parents are hetero-zygous, so each has alleles Ll.

When Ll crosses with Ll, we have

LL 25%

Ll 50%

ll 25%

So out of 180 offspring, we expect about 25% to have short wings, or

25%*180 = 45
