Answer:
number higher than 120/80 Hg are a red flag that you need to take on heart -healthy habits.when your systolic pressure is between 120 and 129 mm Hg and your diastolic pressure is less than 80 mm Hg it means you have elevated blood pressure.
Explanation:
When the diaphragm contracts, the size of the thoracic cavity ________, the pressure inside the thoracic cavity ________, and air flows ________ the lungs. decreases; drops; out of decreases; rises; into increases; drops; into increases; drops; out of
Answer:
decreases; rises; out of
Explanation:
When the diaphragm contracts, the size of the thoracic cavity decreases, the pressure inside the thoracic cavity increases, and air flows out of the lungs.
During the process of breathing out, the diaphragm and the intercostal muscles relax and this leads to a decrease in the volume of the thoracic cavity. Since there is an inverse relationship between volume and pressure, the decrease in the volume of the thoracic cavity leads to an increase in its pressure. Consequently, the lung contracts and air is forced to leave it.
The diaphragm is a muscular structure, which is present below the lungs. The relaxation and contraction of the muscles help in the increasing and decreasing of the thoracic cavity during the breathing process.
The statement for the given blanks are:
When the diaphragm contracts, the size of the thoracic cavity increases, the pressure inside the thoracic cavity decreases, and airflow into the lungs.
The working of the diaphragm can be given as:
1. The diaphragm will contract during the inhalation process. The diaphragm will pull downward which will increase the size of the thoracic cavity and cause a decrease in pressure.
2. The change in the pressure will result in the rushing of air inside the lungs, and will fill up the lungs.
Thus, the contracting and relaxing of the diaphragm will result in the breathing process.

how do animals store long term energy? why?
Answer:
They store it as fat
Explanation:
proteins and carbs can both be converted into fat inside the body. When an animal eats more food than needed, the extra gets converted into fat and stored in adipose cells. During times with low amounts of food, the body can convert the fat into usable energy.
The kind of genes an organism possesses is dependent upon the __________
a. type of proteins in the organism’s nuclei
b. sequence of nucleotides in the organism’s DNA
c. number of ribosomes in the organism’s cytoplasm
d. size of the mitochondria in the organism’s cells
Answer:
B. Sequence of nucleotides in the organism's DNA
Explanation:
The genes within an organism rely on the DNA within those organisms. Different DNA create different genes.
summarize the process of the water cycle.
Answer:
Earth's water is always in movement, and the natural water cycle, also known as the hydrologic cycle, describes the continuous movement of water on, above, and below the surface of the Earth. The hydrologic cycle begins with the evaporation of water from the surface of the ocean. As moist air is lifted, it cools and water vapor condenses to form clouds. Moisture is transported around the globe until it returns to the surface as precipitation. Groundwater either seeps its way to into the oceans, rivers, and streams, or is released back into the atmosphere through transpiration. The balance of water that remains on the earth's surface is runoff, which empties into lakes, rivers and streams and is carried back to the oceans, where the cycle begins again.

What are sister chromatids genetically identical
Answer: Sister chromatids are two identical copies of the same chromosome formed by DNA replication, attached to each other by a structure called the centromere. During cell division, they are separated from each other, and each daughter cell receives one copy of the chromosome.

Are catabolic pathways endergonic or exergonic reactions? Compare the amount of free energy in the reactants to the amount of free energy in the products of a catabolic pathway.
Answer:
Catabolic reactions are exergonic.
Explanation:
Exothermic reactions are catabolic, that is, they catalyze molecules, disintegrate them to be able to release energy to the environment that surrounds them and that is how they release or yield to the environment.
Meditation is a practice of sitting still and quiet for minutes or even hours. It has been practiced for thousands of years and is even a part of religious practices for some people. Carefully controlled, repeated measurements of brain activity have shown that meditation does increase certain chemicals in the brain and even grows the part of the brain that helps people connect with their current surroundings and activities.
Are claims about the effects of meditation most likely scientific or pseudoscientific?
(Answer:) this is most likely to be scientific, (Explanation:) because, if you look at the question it says 'are the effects of medditadion scientific?... ect', and if you look back on your description of meditation, in the third sentence, they certainly state information based on scientific study!
Answer:
scientificExplanation:, because observations of brain growth and chemicals are made carefully and repeatedly

Which of these is one characteristic of topographic maps? A mountain peak. B location of a ravine. C steepness of a slope. D distance between two areas.
Steepness of a slope (C) is one characteristic of topographic maps.
"The more closely spaced the contour lines, the steeper the slope. You can find out exactly how steep the slope of the area you are interested in by subtracting the lowest elevation from the highest, and dividing the result by the horizontal distance."
Plants play a crucial role in the carbon cycle because they do not release carbon dioxide during cellular respiration allow carbon to enter an ecosystem via photosynthesis have special bacteria that live in their root systems are chemically converted into fossil fuels when burned
Answer:
Allow carbon to enter an ecosystem through photosynthesis
Explanation:
Though plants are known to sustain life through the process of photosynthesis. In this process plants simply takes in carbon dioxide and releases oxygen.
However, this is a type of process is considered to be active during the day, while at night plants absorb oxygen and release carbon dioxide
Hence, Plants play a crucial role in the carbon cycle because they "Allow carbon to enter an ecosystem through photosynthesis."

friction
rolling friction
static friction
sliding friction
Answer:
There are four types of friction: static, sliding, rolling, and fluid friction. Static, sliding, and rolling friction occur between solid surfaces. Static friction is strongest, followed by sliding friction, and then rolling friction, which is weakest. Fluid friction occurs in fluids, which are liquids or gases.
During a bacterial infection, macrophages will seek out and engulf the invading bacteria into vesicles via phagocytosis. The bacteria will then be degraded inside the macrophage. Which organelle do you think participates directly in this degradation process
