Answer:

Blood glucose is a sugar that the bloodstream carries to all cells in the body to supply energy. A person needs to keep blood sugar levels within a safe range to reduce the risk of diabetes and heart disease. Blood glucose monitoring measures the amount of sugar that the blood is transporting during a single instant.

. Hope this helps but I can not answer the second part. Hope that it is beneficial to you anyway! :)

(Edit) This might help you figure it out: The relative densities of an object and the liquid it is placed in determine whether that object will sink or float. An object that has a higher density than the liquid it's in will sink. An object that has a lower density than the liquid it's in will float.

Logistic regression is also vulnerable to overfitting. It cannot be applied to a non-linear problem. It will perform poorly with independent variables which are not correlated to the target and are correlated to each other.

Answer:

smooth and involuntary

Two layers of smooth muscle form the small intestine. The outermost layer is the thin, longitudinal muscle that contracts, relaxes, shortens, and lengthens the gut allowing food to move in one direction. The innermost layer is a thicker, circular muscle.

Also smooth muscle is not under our control so is called involuntary

Answer: microwaves

Explanation:

The investigators were most likely using a Telescope that detects ; ( C ) microwaves

From the electromagnetic spectrum provided the wavelength of a microwave is 10⁻²  and the frequency of the microwave is about 10⁸ Hz which is closest to 10⁹ Hz. Given that the frequency detected with the use of the spatial telescope was 1.4 * 10⁹ Hz.

The most likely wave that this telescope would detect is Microwave because its frequency falls within the closest frequency range of the telescope.

Hence we can conclude that The investigators were most likely using a Telescope that detects ; ( C ) microwaves

In bacteria cells, you would find pili (only found in bacteria and archaea) and DNA not contained in a nuclear envelope/nucleus. These are, for the majority, exclusively found in bacteria cells.

In animal cells, you would find lysosomes and centrosomes. These organelles are exclusively found in animal cells.

In plant cells, you would find plastids, such as chloroplasts or amyloplasts. More specifically, chloroplasts are exclusively found in plant cells as they are necessary for photosynthesis to occur.

1. For generating healthy cells to form replacement organs like brains

Stem cells can be used for curing heart disease by regenerating damaged heart tissue. The correct option is 4.

Stem cells are the raw materials of the body, the cells that give rise to all subsequent cells with specific responsibilities.

Under the right conditions, stem cells divide to establish more cells known as daughter cells in the body or in a laboratory.

Bone marrow stem cells, for example, may be able to generate bone or cardiac muscle cells.

This research has resulted in early-stage clinical trials to assess the effectiveness and safety of the product in humans.

Adult stem cells, for example, are currently being examined in people suffering from neurological or cardiovascular disease.

Thus, the correct option is 4.

Explanation:

Plants usually absorb nitrogen from NO3- and NH4+

Nitrogen oxides released into the atmosphere by burning fossil fuels and organic matter is not a source of nitrogen which is available to plants. Thus, the correct option is D.

Plants require nitrogen as it is a macronutrient. The deficiency of this nutrient can cause many diseases. However, plants cannot themselves obtain the nitrogen from air but they rely mainly on the supply of combined nitrogen atom in the form of ammonia molecule, or nitrate molecule, resulting from the nitrogen fixation through free-living bacteria in the soil or the bacteria living symbiotically in the nodules on roots of legumes.

Plants can take nitrogen through absorbing the soil by their roots. Plants cannot get this nitrogen directly from the air. Although, the nitrogen element is abundantly available in air. Nitrogen is unreactive atom, and it cannot be used by the green plants to make proteins. Nitrogen gas needs to be converted into nitrate compounds in the soil through nitrogen-fixing bacteria in soil, root nodules or lightning. Every nitrogen atom is triple-bonded to another nitrogen atom to form the molecular nitrogen, N₂.

Therefore, the correct option is D.

Answer:

14. f. diffusion

15. a. excreting waste

16. b. exocytosis

17. a, endocytosis

Explanation:

14. The movement of molecules from a high concentration to a low concentration is diffusion. Active transport uses energy to move molecules against their concentration gradient (from low to high). Osmosis specifically refers to water molecules. Endocytosis is the movement of molecules inside the cells via the cell membrane engulfing it.

15. The membrane controls the substances that enter and exit the cell, therefore it is involved in excreting waste products from inside the cell.

16/17 Endocytosis is engulfing substances to bring them inside the cell. Exocytosis is the reverse process, where substances exit the cell by fusing with the cell membrane. The movement of molecules from a high concentration to a low concentration is diffusion.  Osmosis specifically refers to water molecules.

Okay, I got this from google and my notes but the cells inside of a cell membrane are composed primarily of fatty-acid-based lipids and proteins.

Explanation:

Membrane lipids are principally of two types, phospholipids and sterols (generally cholesterol). These membranes are composed primarily of phospholipids and proteins and are typically described as phospholipid bi-layers. They also contain cholesterol in the phospholipid bilayer.

Answer:

Flu vaccinations are fundamental as they reduce the risk of flu illness by over 50%.

Explanation:

Flu vaccinations reduce the risk of flu illness by over 50%. This makes this process extremely important and fundamental for all human beings as they not only protect the person who gets the vaccine, but it also contributes to the prevention of spreading to other people, especially children and older adults who possess a greater risk of developing flu complications.

The antibodies that are produced by the vaccine prevent the flu virus from attaching to a healthy cell. However, if a person has not been vaccinated, the virus will attack the healthy cells because there is an absence of antibodies that prevent this process.

Mass is not conserved in chemical reactions. ... This means that the total mass and energy before a reaction in a closed system equals the total mass and energy after the reaction. According to Einstein's famous equation, E = mc2, mass can be transformed into energy and energy can be transformed into mass.

Explanation:

Answer:

Mass is not conserved in chemical reactions. The fundamental conservation law of the universe is the conservation of mass-energy. This means that the total mass and energy before a reaction in a closed system equals the total mass and energy after the reaction. According to Einstein's famous equation, E = mc2, mass can be transformed into energy and energy can be transformed into mass. This is not some exotic process, but in fact happens every time there is a reaction. Mass is therefore never conserved because a little of it turns into energy (or a little energy turns into mass) in every reaction.
