Answer:
The answer is geothermal (b)
The correct answer is B. Geothermal.
This is true because geo relates to the earth and thermal relates to heat.
When you put those two words together, it means heat from the earth.
A is incorrect since the energy sources comes from the fission or splitting of atoms.
C is incorrect since solar energy relates to heat or energy from the sun.
D is incorrect since hydro means water and therefore hydroelectricity is an energy source that is made from water.

The diagram shows part of the carbon cycle. (sorry I cant add it but it includes carbon dioxide in the atmosphere, green plants, animals and microorganisms)
Describe how living things are involved in the constant cycling of carbon.
Answer:Most living things breathe out carbon dioxide(Co2)
Explanation:
Most living organisms need oxygen to survive(Animals and microorganisms).They therefore breathe in oxygen and breathe out carbon dioxide save for green plants which give out oxygen and take in carbon dioxide.
Animals and plants exchange oxygen for carbon dioxide and vice verca
Hereby involving living things in the constant cycling of carbon dioxide in the atmosphere.

Answer: 1. How can a healthy lifestyle lead to a healthy heart.
The heart is one of the vital if not the most vital organ of the human body,this is because it is the heart that pumps blood into systemic circulation so that the other body organs,tissues and cells can function adequately.
Any disease or injury to the heart virtually affects all other parts of the body. Therefore a healthy and proper functioning heart is important and this can only be achieved through a healthy lifestyle.
Lifestyles such as;
- Regular exercise/physical activity which will help one to loose excess weight and maintain physical fitness because when one is overweight,fat deposits on the wall of the artery narrowing the lumen/wall, this in-turn causes blood to exert more pressure as it moves through the artery and in-turn lead to hypertension and other heart conditions.
- Stop or limit the intake of alcohol because it increases your chances of getting stroke,heart attack and hypertension through the damage of heart muscles.
- Drinking enough water; this helps the kidney to filter away waste from the body preventing the waste from building up/accumulating in the body especially the heart and as such causing heart problems.
Managing of stress very well to prevent a higher risk of heart disease.
-Eat a healthy diet and manage your blood cholesterol level to prevent damage to heart muscles and blood vessels which will in-turn lead to cardiovascular disease.(High density cholesterol HDL is the good type of cholesterol and low density cholesterol (LDC) is bad for the body.
- Regular visit to a cardiologist when one has a family history of hypertension or any other heart disease.
2. HOW IS HYPERTENSION A BLOOD RELATED DISEASE?
Hypertension is a blood related disease because hypertension is caused when the force of blood along the lumen of artery (artery wall) is higher than normal. This exerted pressure by the blood gets too intense enough to cause a heart problem or a hear disease.
When the pressure gets too intense enough to rupture the artery wall,the individual comes with a heart condition known as stroke.

When taking a person's blood pressure, after proper inflation of the cuff, the first pulse sound that is heard through the stethoscope indicates that blood is flowing through the artery past the cuff. The reading on the pressure gauge at this point represents:_________.
Answer:
Diastolic pressure
Explanation:
The reading on the pressure gauge at this point represents the Diastolic pressure. In a medical context, this is the pressure of the blood in the arteries when the heart is filling. In the numerical readings, this is represented by the lower end of the two blood pressure measurements. For example, if the individual's blood pressure is taken and the measurement of 120/80 is taken, then 80 is the diastolic pressure in this scenario.

Answer:
The correct answer is - hydrophobic and nonpolar.
Explanation:
Phospholipids are amphipathic molecules which means they show the both hydrophobic and hydrophilic properties. This property is due to the fact that they have a phosphate head that is hydrophilic, and polar while there are also two hydrophobic nonpolar fatty acid tails.
The fatty acid chains have a cis double bond and are the uncharged, nonpolar tails, which are hydrophobic.
Thus, the correct answer is - hydrophobic and nonpolar.
Through a microscope, you can see a cell plate beginning to develop across the middle of a cell and nuclei forming on either side of the cell plate. This cell is most likely Group of answer choices
Answer:
the cell is most likely a plant cell in cytokinesis
Explanation:
Cytokinesis simply means the division of the cytoplasm. It happens after the telophase stage of the cell division and leads to the formation of two distinct cells.
Cytokinesis in animal cells involves the constriction of the plasma membrane from the equator of the cell outward until two distinct cells result. The process starts from the anaphase and continues through the telophase stage of the cell division.
Due to the presence of cell walls in plant cells, cytokinesis does not just involve the constriction of the plasma membrane but the formation of cell plates at the equator of the cell. The cell plate fuses with the plasma membrane, eventually dividing the cell into two with the formation of cell walls between the two membranes of the cell plate.
The cell is most likely a plant cell undergoing cytokinesis.
CYTOKINESIS:
Cytokinesis is the process whereby the cytoplasm divides into two halves. Cytokinesis proceeds nuclear or mitotic division. Cytokinesis occurs in both plant and animal cells with similar result, however, they occur differently. In plant cells, a cell plate forms in between the cell, which serves as the point of division into two cells. However, in animal cells, a cleavage furrow is rather formed. Therefore, the cell observed to be forming cell plate is most likely a plant cell undergoing cytokinesis.Learn more: https://brainly.com/question/10606931?referrer=searchResults

Q. 35 One treatment for high blood pressure is taking diuretics that prevent the kidney collecting ducts from reabsorbing water. How would diuretics reduce blood pressure? By increasing blood volume By decreasing blood volume By increasing heart rate By decreasing heart rate
The diuretics will increase the volume of urine. That means more water is taken from the blood and excreted. According to Boyle's law, the volume is proportional to the pressure(p1v1=p2v2). It means that if we decrease the volume of blood we also decrease the pressure.
That means second option

Explanation:
which following pairs of body functions are normally involuntary actions but can be controlled voluntary for a short periods of time
Explanation:
Medulla oblongata controls consciousness and arousal (the reticular formation) and its three vital reflex centers control the blood vessels diameter, heartbeat and breathing rate (the involuntary actions). This makes option D correct. The lower part of brain stem forms the hind brain which comprises of medulla oblongata, pons and cerebellum. This makes option C incorrect as medulla is not part of forebrain. Cerebellum is the convoluted subdivision of brain stem and is associated with coordination of muscular movement, muscle tone and balance i.e. the voluntary actions. Option B is incorrect. Spinal cord, along with brain, forms central nervous system which serves to integrate the sensory inputs from internal and external environment as received by sensory neurons and process and finally transmit the nerve impulses to effectors (muscles and glands). This makes option A incorrect.

What happens when organisms populate a new area and are isolated geographically from other populations of the same species?
Answer:
The geographically isolated population will acquire genetic differences that eventually will lead to its speciation
Explanation:
Geographic isolation is a biological process produced by the physical separation between organisms of the same species, which may be caused by different types of geographical barriers such as, among others, mountains, earthquakes, rivers, etc. Geographic Isolation produces genetic differences between the separated groups. Over time, these genetic differences will lead to the reproductive isolation of the new population, thereby leading to the formation of a new species in the course of evolution, in a mechanism referred to as speciation.
