how does heat from the sun warm the earth?
Answers
Answer: the sun heats the earth through radiation
Explanation:
Answer:
Heat from the sun may warm the Earth when greenhouse gases absorb infrared radiation (IR), which you cannot see but can feel as heat. Dark surfaces also play a huge role in heating up Earth's surface, as they reflect less light and absorb most of the energy from the sun, in contrast to lighter surfaces, which reflect more light than it absorbs.

A healthy diet consists of carbohydrates, fats, and proteins. Proteins are broken down into amino acids that are recombined to make many of the body's structures, such as muscle. Eating protein regularly is of utmost importance because ____________.
Answers
Answer:
"Protein is an important component of every cell in the body. ... Your body uses protein to build and repair tissues. You also use protein to make enzymes, hormones, and other body chemicals. Protein is an important building block of bones, muscles, cartilage, skin, and blood."
"They must be consumed in the diet. Everyone needs 8 of these amino acids: isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. Infants also need a 9th one, histidine.
The percentage of protein the body can use to synthesize essential amino acids varies from protein to protein. The body can use 100% of the protein in egg and a high percentage of the proteins in milk and meats. The body can use a little less than half of the protein in most vegetables and cereals.
The body needs protein to maintain and replace tissues and to function and grow. Protein is not usually used for energy. However, if the body is not getting enough calories from other nutrients or from the fat stored in the body, protein is used for energy. If more protein is consumed than is needed, the body breaks the protein down and stores its components as fat.
The body contains large amounts of protein. Protein, the main building block in the body, is the primary component of most cells. For example, muscle, connective tissues, and skin are all built of protein.
Adults need to eat about 60 grams of protein per day (0.8 grams per kilogram of weight or 10 to 15% of total calories). Adults who are trying to build muscle need slightly more. Children also need more because they are growing. People who are limiting calories to lose weight typically need a higher amount of protein to prevent loss of muscle while they are losing weight. "

Found: A Plant-Eating Spider. Spiders are meat-eaters. Until recently, scientists thought that was true for the roughly 40,000 spider species in the world. Now, researchers have discovered a spider that eats mostly plants. Bagheera kiplingi, a jumping spider, lives in Central America and Mexico. It nests in the leaves of acacia tree. Scientists have long known that ants live in these trees. The ants eat the tree’s little yellow vegetables. But scientists had no idea that the spiders eat the vegetables too. Is competition likely to occur between the Bagheera kiplingi and ants living in acacia trees? Support your answer. *
Answers
Answer:
Yes, competition is likely to occur
Explanation:
Competition is an ecological interaction between organisms of the same or different species, resulting in the detriment of one of the organisms. Competition is generally caused when organisms in an ecosystem occupies the same niche i.e. they rely on the same ecological resource, which could be food, mate, space etc.
The case described in this question involving a Bagheera kiplingi (jumping spider) and acacia ants will likely result in competition because they both occupy the same habitat and feed on the same food (vegetable plant). The two organisms will have to compete for this limited resource, hence, it is regarded as an INTERSPECIFIC COMPETITION because it involves two different organisms.

Immune system overreacts to an antigen part of the immune system does not function properly the body's immune system attacks its healthy cells, mistaking them for pathogens masses of cells form and steal nutrients from healthy.
What do you mean by Allergy?Allergy may be defined as a reaction by our immune system to something that does not trouble most other people. It affects a person more specifically.
When a person gets affected by any allergy, the immune system of that person may overreact by producing more antibodies. These antibodies attack the allergen particles and cause adverse symptoms.
A person who has allergies has them because his or her body over reacts to a material that would otherwise be ignored. It is an overreaction of the immune system triggering a immune attack response that is unneeded.
Therefore, a person who has allergies has a compromised immune system because the body's immune system overreacts to an antigen.

Examine the diagram of the carbon cycle shown above. Through which of the following processes is carbon removed from the atmosphere?
Answers
Answer: photosynthesis
Carbon dioxide is naturally removed from the atmosphere by photosynthesis, and trees are particularly skilled at storing the carbon that is removed from the atmosphere by photosynthesis.
What processes is carbon removed from the atmosphere?Respiration and photosynthesis are polar opposites of one another. Through photosynthesis, CO2 is taken from the atmosphere and exchanged for O2. During respiration, O2 is taken from the surrounding air and replaced with CO2. However, none of these processes are in balance.
Plants use photosynthesis to transfer atmospheric carbon into the biosphere and transport it up the food chain. They make sugar molecules by chemically combining water's hydrogen and oxygen with carbon dioxide using energy from the sun.
Therefore, Plants open small pores on the surfaces of their leaves during photosynthesis in order to absorb carbon dioxide from the atmosphere and create their own sustenance.

Describe the various defense mechanisms your body has to fight pathogens, nonspecific and specific. How does not washing your hands properly affect these mechanisms?
DO NOT COPY AND PASTE I WILL CHECK AND YOUR ANSWER WILL BE DELETED :)
Answers
The human body has several defense systems to deal with both generalized and specific infections. Specific defenses are targeted responses that identify and eradicate particular diseases, while nonspecific defenses are general processes that protect the body against a variety of pathogens.
What are Specific and Non-specific defenses?Physical barriers such as skin and mucous membranes, which prevent infection from entering the body, are examples of nonspecific defenses. Additional general protections include:
1. Inflammation:
A local response to injury or infection, known as inflammation, involves the mobilization of immune cells to the site of injury or infection to get rid of pathogens and encourage tissue healing.
2. Fever
Fever is an increase in body temperature that can aid in the fight against infection by slowing the growth of certain bacteria and increasing immune cell activity.
3. Phagocytosis
Pathogens are engulfed and destroyed by immune cells through a process called phagocytosis.
Specific pathogen exposure leads to specific immune responses known as specific defenses. These defenses require immune cells to recognize pathogens and mount a focused attack to destroy them. Special defenses include:
1. Production of Antibodies: Specialized immune cells make antibodies that can recognize and combat particular infections.
2. T cell activation is the process through which specialized immune cells known as T cells activate and kill cells that are infected with particular diseases.
3. Immune memory is the ability of the immune system to remember and respond more successfully to particular infections it has previously encountered.
When you don't wash your hands enough, you introduce viruses into your body and weaken both non-specific and specific defense mechanisms. For example, if you touch your face after touching a contaminated surface, you may introduce pathogens through your mouth, nose, or eyes, bypassing physical defenses against infection. By making the body's defenses less efficient and increasing the risk of infection, it can make it easier for microorganisms to cause disease.
Therefore, the human body has several defense systems to deal with both generalized and specific infections.
