Answer:
Blood flow is decreased below normal due to the build of of plaque in the arteries causing an increase in blood pressure.
Explanation:
When fats, cholesterol,calcium , water builds up on the endothelial lining of the Coronary arteries,reducing the diameter,and therefore impeding the flow of blood,these build up is called Plaque.The diseases condition that arise from this called atherosclerosis.
With continue build up the plaque changes in the chemical components.becomes hardened, further reducing the diameter,blood volume available and therefore oxygen supply to the targeted tissues( cardiac muscles) of the heart.This leads to Ischemic heart diseases e.g chest pain-Angina. With these strokes and other complication may follows due to cut off in oxygen and nutrients rich blood to the tissues of the brains for the heart.
The impedance to the blood flow,forced load on the heart to pump blood and therefore High blood pressure.This is the problem with Steve CVS.

Provides an image that is a three-dimensional representation with little magnification
Answer:
Scanning electron microscope
Explanation:
The scanning electron microscope is a device that allows a viewer to observe very small structures that are invisible to the naked eye. The great difference of this microscope in relation to the others, is that it allows the images to be visualized in three-dimensional structures with little magnification, which allows the full visualization of structures, topographic aspects and compositions of the samples visualized by it, thus allowing them to be scientific studies with more precision and accuracy.

According to the data collected by the Economic Policy Institute, what is the relationship between annual earnings and education attainment?
Defined as variation of life on Earth, ____________ is the number and relative abundance of different species.
Answer: Diversity
Explanation: The earth is composed of different species of organisms spread across various parts and regions of the earth. The idea of having varying classes of species scattered on the earth is called diversity culled from the word diverse, which is used to describe a property of Variation in component. Hence, diversity explains the variation in the number and size of different species, culture and languages (biodiversity) and other components of the human existence. Additionally, the concept of diversity helps us realize the need to respect and embrace our differences in other to foster progressive relationship.
Botany Professor. Dr. Noa Nkembe. is conducting research over how temperature effects the toxicity of Toxicodendron diversilobum (poison oak). He grows the plant in controlled environments that are kept at temperatures that vary by just 0.05 degrees Celsius. Which of the thermometers would be the BEST choice for him to use for this experiment? Justify your answer. A.Glass thermometer B.Temperature probe C.Temperature strip
Answer:
The correct answer is - option A. Glass thermometer.
Explanation:
Glass or basal thermometers are the instruments that are use to measure temperature of any surface or organism. These are best choice for the measuring smaller changes in the temperature which can vary up to 1/10th of the degree to 1/100th of the degree.
In this case the temperature variation is 0.05 in the environment of the Toxicodendron diversilobum (poison oak) which can easily be monitor with the help of this glass temperature.
Thus, the correct answer is - option A. Glass thermometer.

Answer:
digestive also know as homostasis
Explanation:
Did the enzymes from Claire's small intestine break down the
protein at a low, normal or high rate?
Answer: low rate
Explanation:
Claire is a Great Dane who was losing weight despite the fact that she is eating. Claire doesn't have an increase in appetite and also doesn't have enough energy that is required for her to play.
Claire is losing weight because food the enzymes in her body doesn't break down the food that she eats. When compared to a dog that was healthy, the enzymes from Claire's small intestine broke down protein at a low rate.
Small intestine of Claire break down the protein at a low rate.
The enzymes from Claire's small intestine break down the protein at a low rate because the proteases is present in a very low amount in the small intestine. The proteases enzyme is responsible for the break down of proteins.
If proteases is present in large amount then the protein present in food is broken down at a faster rate while on the other hand, if the proteases is present in small amount then more time is needed to digest the protein so that's why Claire's small intestine break down the protein at a low rate.

What forms at a divergent plate boundary such as in the middle of the Atlantic Ocean?
a) Tall mountains
b) Deep valleys
c) Sea mounts
d) Under sea ridge
Answer:
The Mid-Atlantic Ridge (MAR) is a mid-ocean ridge, a divergent or constructive plate boundary located along the floor of the Atlantic Ocean, and part of the longest mountain range in the world. In the North Atlantic, it separates the North American from the Eurasian Plate and the African Plate, north and south of the Azores Triple Junction respectively. In the South Atlantic, it separates the African and South American plates. The ridge extends from a junction with the Gakkel Ridge (Mid-Arctic Ridge) northeast of Greenland southward to the Bouvet Triple Junction in the South Atlantic. Although the Mid-Atlantic Ridge is mostly an underwater feature, portions of it have enough elevation to extend above sea level, for example in Iceland. The ridge has an average spreading rate of about 2.5 centimetres (1 in) per year.[1]

Trevor wanted to find out what fertilizer worked best for growing marigolds. He put Miracle Grow on one, Scotts fertilizer on another, and no fertilizer on the third marigold. What is the control?
a. Marigold with no fertilizer
b. Type of fertilizer
c. Plant growth
d. Amount of water
Answer:
a. Marigold with no fertilizer
Explanation:
An experiment contains variables including independent and dependent variables. The independent variable is the variable that is changed by the experimenter, which is the TYPE OF FERTILIZER in this case, while the dependent variable is the measured variable, which is the GROWTH OF MARIGOLDS in this experiment.
However, a control group is a group that does not receive any experimental treatment. In other words, the independent variable is unchanged in the control group. The control group is regarded as the "normal" used to compare with the experimental group (group that receives treatment). In this experiment, the group of marigolds that DOES NOT RECEIVE FERTILIZER is the control group.

A scientist is studying a cell and can clearly see that it has ribosomes and mitochondria. Which statement best describes how the cell could be classified?Which structure is unique to eukaryotic cells?
Answer:
The cell is eukaryotic because it contains mitochondria.
nucleus
Explanation:
The statement that best describes the way in which the cell would be classified is that the cell is eukaryotic because it contains mitochondria. The correct option is D.
What is eukaryotic cell?A eukaryote would be any cell or life form with a well-defined nucleus. The nucleus of a eukaryotic cell is surrounded by a nuclear membrane, which contains well-defined chromosomes.
The main difference between these two varieties of organisms is that eukaryotic cells have such a membrane-bound nucleus, whereas prokaryotic cells do not. Eukaryotes stockpile their genetic information in the nucleus.
Prokaryotes are organisms that lack a nucleus and various organelles in their cells.
Prokaryotes are classified into two groups namely bacteria and archaea, each of which has its own evolutionary lineage, according to scientists.
Thus, the correct option is D.

All autotrophs produce valuable organic molecules. What makes these organic molecules so valuable to living organisms
Answer:
The valuable organic molecules produced by autotrophs serve as sources of food for the heterotroph and supply the necessary nutrients living organisms need to grow and survive.
Without these valuable organic molecules living organisms can not survive , grow and develop.
The organic molecules serve as sources of energy needed to fuel biological processes in the organisms.
Explanation:
Autotrophs are group of organisms that can produce their own food through the process of photosynthesis where inorganic molecules are converted to organic molecules i.e they use light energy from the sun with water and carbondioxide to produce carbohydrates and oxygen.
Heterotrophs or other living organisms depend on autotrophs for the supply of organic matter as food nutrients and sources of energy needed for cellular or biologic processes.
