Explain how is sunlight distributed across the world

Answers

Answer:

The sun is distibuted across the world due to The environment works in a similar way to a car's heat engine. Winds, precipitation, and evaporation processes in the atmosphere, on the other hand, spread the sun's energy across the Earth. Conduction, convection, and radiation are the methods through which heat energy is transferred.

Explanation:

I took earth science

On Earth, sunlight is scattered and filtered through Earth's atmosphere, and is obvious as daylight when the Sun is above the horizon. When direct solar radiation is not blocked by clouds, it is experienced as sunshine, a combination of bright light and radiant heat.

In a large population of sea stars, half of the individuals possess the red allele and half possess the purple allele. A change in the genome has been introduced, and many of those with purple allele are dying. Therefore, the red allele has become more frequent over time.

Which of the following requirements for the Hardy-Weinberg equilibrium is not being met?

Answers

Answer:

A

Explanation:

All mating must be totally random

Hardy-Weinberg equilibrium is a mathematical model that describes the genetic equilibrium of a population in terms of allele frequencies. It states that allele frequencies in a population remain constant over time in the absence of any evolutionary forces.

What are the requirements of the law ?

In order for this balance to be maintained, five basic requirements must be met: large population size, random mating, no mutations, no migration, and no natural selection. In this case, the starfish population does not satisfy the fifth requirement for no natural selection.

Natural selection occurs as individuals with the purple allele die off, resulting in the red allele becoming more common over time. This type of directional selection causes allele frequencies to deviate from Hardy-Weinberg equilibrium.

Therefore, no natural selection requirement is met in this starfish population. This causes allele frequencies to change over time, leading to a deviation from Hardy-Weinberg equilibrium.

Answer:

during interphase......

The diagram below represents the time a cell spends in the two main phases
of the cell cycle. Which section of the diagram represents the phase during
which the cell divides, and what is this phase called?
A. Yellow area: Interphase
B. Yellow area: M phase
C. Blue area: M phase
0 D. Blue area: Interphase

Answers

Answer:

The yellow ares is m-phase

Explanation:

This is where the cell divides into two nucleus.

The blue area in the diagram represents the phase during which the cell divides, and this phase is called the M phase or mitotic phase. Therefore, option C is the correct.

What is mitotic phase?

The mitotic phase, also known as the M phase, is the phase of the cell cycle during which a single cell divides into two identical daughter cells. This process of cell division is essential for growth, development, and repair of tissues in multicellular organisms.

The M phase consists of four stages: prophase, metaphase, anaphase, and telophase. During these stages, the replicated chromosomes condense and align at the metaphase plate, separate and move towards opposite poles of the cell during anaphase, and then decondense and form two separate nuclei during telophase.

The M phase is tightly regulated by a complex network of checkpoint pathways that ensure the accurate segregation of chromosomes and prevent the formation of abnormal cells, which can lead to diseases such as cancer.

D. The food is completely digested and is absorbed by tiny blood vessels in the
walls of the stomach​

Answers

Answer:

C) Juices mix with the food and stomach muscles squeeze it.

Explanation:

Gastric juices are added in your stomach to turn your food into small particles that can be gobbled up by cells. Your body contains dangerous level of acids such as HCl but your cell lining in your inner cavities of your stomach prevent acid from burning you form within! Fun :D

So technically the answer is C.

After the food enters your stomach the stomach muscles mix the food and liquid with digestive juices. The stomach slowly empties its contents called chyme into your small intestine

A culture of cells is placed in a chamber and exposed to high pressure for Reset Nex​

Answers

Answer:

B. A person spends one hour each day under the ultraviolet rays of a tanning bed.

Explanation:

Genomics refers to the scientific study of genes (DNA) found in living organisms such as humans and animals.

A genome can be defined as the complete set of hereditary instructions that is typically found in the deoxyribonucleic acid (DNA).

Deoxyribonucleic acid (DNA) is an organic complex-molecular structure found in all living organisms.

Basically, it comprises of genes and is essentially the foundation block of all living organisms such as humans, animals and plants.

Mutation can be defined as an alteration in the DNA sequence (nucleotide sequence) of a cell of a living organism either due to improper transcription, genome editing or environmental factors such as smoking, ultraviolet (UV) light, etc.

Hence, when a person spends one hour each day under the ultraviolet rays of a tanning bed, it's most likely to cause a DNA mutation. A continuous exposure to ultraviolet (UV) light would cause an uncontrolled division of certain body cells, which then invade the surronding tissues and interfere with the normal functioning of the body.

2. What else would you need to know to come up with a plan of action? Where could you

Answers

Answer:

1. Moving the facilities such as crops, lawns, golf courses, and sewers etc would be unrealistic to change because many of the owners would not comprise (costs so much already), yet there are solutions. For example, the town can restrict farmers from poluting the rivers with pesticides as well as fining them and the house developments golf courses and land owners in which the money can be used towards the filteration cost. Another idea would to build cheaper wells to soak up water from different river locations or build barriers around settlements from the river. Another idea would to simply grow natural filters such as using the trees and soil they already had.

2. Of course their are limits such as costs, and figuring out the landscapes of where to build wells, add soil and trees (trees take time to grow) and more that would need plan of action from community leaders in which the people would need to speak with the advisors or the management of the buildings nearby. Without clean water people will get sick or die, and building managers need healthy people to live in their houses and work and grow crops so they'll have to make change.

How do white blood cells protect the body against infections

Answers

Answer:

White blood cells, which are also called leukocytes or white corpuscles, are a cellular blood component that does not include hemoglobin, have a nucleus, are motile, and protect the body from infections and diseases through ingestion of foreign materials and cellular debris, destruction of infectious agents and cancer cells or production of antimicrobials.

Explanation:

There are 4,500 to 11,000 cells in the white blood of a healthy adult person per cubic mm of blood. During the day, fluctuations in the number of white cells take place; lower values during rest and higher during exercise are attained. The quantity of white cells increases abnormally, while the number decreases abnormally, Leukopenia.

Intensive physical activity, seizures, extreme emotional response, pain, pregnancy, labor, and specific conditions such as infections and intoxications may increase the counting of white cells. In reaction to some types of infections or medication, or in conjunction with certain illnesses such as chronic anemia, malnutrition, or allergy, the number may drop.

If something is 12 grams and has a volume of 1.6 cubic centimeters, how many grams per cubic centimeter.

Answers

Answer: 7.5  grams per cubic centimeter.

Explanation:

We area given that , Mass of something is 12 grams

Volume of that thing is 1.6 cubic centimeters

To find gram per cubic centimeters, we will divide Mass by Volume ( which computes Density)

Number of gram per cubic centimeters = [tex]\dfrac{12}{1.6}[/tex]

Number of gram per cubic centimeters = 7.5

Therefore, 7.5  grams per cubic centimeter. (density of the thing)

Answer:

Flat discs inside chloroplasts that are arranged in stacks are called (2) __thylakoids_. (3) __Pigments__ are light-absorbing substances that are inside chloroplasts. They absorb light of different (4) __wavelenghs__. The green pigment in plants that is essential for photosynthesis is (5) __Chlorophyll __. Light energy absorbed by this pigment excites (6) ____electrons___. They are transferred to a(n) (7) _Electron Carrier_. Then they move down an electron transport chain.

Explanation:  

The chloroplasts are limited by an outer membrane and an inner one.  In the middle of the two membranes, there is a space left called intermembrane space. In the interior of the inner membrane, there is another space known as the stroma. Within the stroma, there is the third system of membranes, known as thylakoids. They are disk-shaped structures, limited by a membrane, and in their interior, there is a space named thylakoid space.

Thylakoids are arranged as piles, receiving the name of grana. Grana connect to each other by a longer thylakoid membrane. The photosynthetic pigments are placed in the thylakoids, where it occurs light-dependent reactions. These molecules are in charge of light absorption. The most common pigment is chlorophyll, which provides the typical green color of plants. When sunlight reaches the pigments, electrons get excited and move along the electron transport chain, places in the thylakoid membrane.  This process occurs during photosynthesis, while new electrons provided by water molecules replace the excited ones. The final products are oxygen, ATP, and NADPH.  

In the stroma, it takes a place the Calvin cycle.
