Answer:

Histamine is a substance that is released by the body during an allergic reaction. Mast cells, which are a type of white blood cell, release the histamine, and this triggers a process which is most commonly referred to as the “inflammatory immune reaction”.

Explanation:

Antihistamine solutions can reduce allergies. I am allergic to mosquito bites.

The cells release histamine during allergic responses are the mast cells.

Eosinophils, mast cells, and basophils all have been first diagnosed and defined with the aid of using Paul Ehrlich withinside the past due nineteenth century. Since then, it has end up clean that those 3 cells kinds have an awful lot extra in not unusualplace than their popularity with the aid of using the equal scientist.

Mast cells are multifunctional bone marrow-derived tissue-residing cells which might be the principal manufacturer of histamine withinside the frame. H1R are expressed in lots of cells, along with mast cells, and are concerned in Type 1 hypersensitive reaction reactions.

Microtubules near the cell plate are the motor proteins that move chromosomes toward the poles of the mitotic spindle located.

Motor protein are defined as a group of molecules with the ability to travel across the cytoplasm of animal cells. Molecular motors called motor proteins move along the cytoskeletal filaments of the cell by hydrolyzing ATP. They provide a variety of tasks for biological systems, such as facilitating intracellular trafficking along biopolymer filament tracks and regulating filament sliding during muscle contraction.

Microtubules are defined as the cytoskeleton is made up of tubular-structured polymers, which are present throughout the cytoplasm. Microtubules play a variety of roles in dividing cells, including the construction of the mitotic spindle and axon extension in neurons.

Thus, microtubules near the cell plate are the motor proteins that move chromosomes toward the poles of the mitotic spindle located.

1. Check your pulse before doing the stair master. Do 2 minute intervals on the stair master then check your heart rate again. What is the difference between your heart rate before and your heart rate now?

2. Going up the stairs for 2 minutes and looking at heart rate differences is the expierement. This should last about 10 minutes. An oximeter needs to be used for best results on the heart rate. The excercise should be as consistant as it can be.

3. Your heart rate should keep increasing until you reach your max heart rate

4.  2: 72

    4: 78

    6: 82

    8: 100

    10: 118

5. just copy numbers into graph

6. My predictions were pretty accurate. Your heart rate should gradually rise until you hit your max heart rate. The body needs more oxygen to maintain homeostasis which leads to increased heart rate. I didn't track how fast we were going every 2 minutes (I didn't stay at the same speed as I did in the beginning). Not changing the speed as time goes on and monitering the speed.

Answer:

When the water gets too warm, the algae can no longer live inside corals, so they leave. The corals then turn from green to white, called coral bleaching. Climate change has been causing the Earth's air and oceans to get warmer. With warmer oceans, coral bleaching is becoming more widespread.

Explanation:

When the water temperature rises too high, algae can no longer live inside corals and leave. Coral bleaching occurs when the corals turn from green to white.

A coral reef is an underwater ecosystem characterized by corals that build reefs. Reefs are made up of coral polyp territories hosted along by calcium carbonate.

The vast bulk of coral reefs are mainly composed of stony corals, which have polyps that coalesce together.

Coral reefs grow in shallow water with temperatures ranging from 68° F to 97° F. The Indo-West Pacific biogeographic region contains more than 90% of the world's coral reefs.

When the temperature of the water rises too high, algae can no longer live inside corals and must leave. Coral bleaching occurs when corals alter color from green to white.

The Earth's air and oceans are becoming warmer as a result of climate change. Coral bleaching is becoming more common as the oceans warm.

Thus, this is the effect of water temperature on corals from inshore and offshore reefs.

Answer:

Explanation:

The cellular process of releasing energy from food through a series of enzyme-controlled reactions is called respiration . Some of the energy released is used to produce ATP. Some of the energy released is lost as heat.

The release of energy from carbohydrates takes place within the

mitochondria.

The mitochondria is an organelle found within cells and it is regarded as

the power house of the cell. This is because energy is generated in it which

gives the cells power to perform its daily activities.

Energy generated from carbohydrate is usually in the form of ATP and it

involves series of reactions such as glycolysis, kreb cycle etc to ensure

adequate energy yield.

Pseudopodia are formed by some cells of higher animals (e.g., white blood corpuscles) and by amoebas. During amoeboid feeding, pseudopodia either flow around and engulf prey or trap it in a fine, sticky mesh.

Chemical composition of dorsal spines provides information about its function as regulation of body temperature.

The dorsal spines were not used to support a hump or to regulate body  temperature because of the chemical composition of the spines. Ibrahim found that the spines were made up of bones having few blood vessels and were likely wrapped tightly in skin which can't perform the function of thermoregulation in the body.

In order to regulate temperature of the body, more blood vessels are needed and we know that in dorsal spines the structure is bony and less number of blood vessels so we can conclude that chemical composition of dorsal spines provides information about its function as regulation of body temperature.

It is beneficial to study plant and animal compounds for a multitude of reasons such as Sanitation, Bacterial fighting, and many more. An example of a plant compound that has benefited humanity would be penicillin which is derived from plants, it is considered the first true antibiotic.

Explanation:

Before 1928, humanity had conquered most of its enemies and people were only limited in lifespan by internal mechanisms being disrupted or failing, such as cancer, genetic errors,viruses, and BACTERIA. But in 1928 by accident a scientist discovered penicillin and finally deaths by bacteria were dropping to the point where in the past a mere cut could mean death by bacterial infection when compared to the present, humanity now doesn’t even consider bacterial infection, and that is all due to the power of penicillin and other antibiotics.
