Answer:
My natural motivation to eat anything I like has been altered.
The internet as a media is rife with various information about the nutritional composition of certain foods and what they can do to the body. So it easy for me, instead of hiring the services of a nutritionist, to google search "foods that increase body metabolism" and be bombarded with millions of search results with mixed content from authoritative and nonreliable sources.
So the primary challenge is to sift through all of that information for authentic advice. The secondary is to act on this newly acquired information. The bottom line is that I have become very intentional about my choice of food.
Cheers!

What's Inside a Black Hole?
Exposing skeletal muscle fibers to ________ removes ions and ATP from the cells and disrupts the troponin-tropomyosin complex such that it can no longer block the active sites on the actin molecules.
Answer:
Glycerine/Glycerin
Explanation:
This is a colourless ,odourless syrup liquid which is sweet to taste .it is non toxic,it is also refers to as glycerol.Its medicinal uses includes anti bacteria and anti viral for wound treatments,and as a marker in liver diseases.
Chemically it contains three hydroxyl (OH) group bonded together.This structure is an adaptation for dissociation in water and also accounts for its hygroscopic nature.
When a muscle fibre is exposed to Glycerine,these cells contracts,reducing the space among the cells.Hence the fibres contraction is affected,follow by reduction in length.
Basically, during glycerine is applied to muscle cells,this substance punctures the sacolemma, creating holes.The latter aid the diffusion of ca+ and ATPs across this membrane in the muscle cells.
Generally the ca+ from the Sacroplasmic reticulum binds with the troponin,leading to the change in its shape to bind with the actin filament.Protein tropomyosin also binds with the actin filaments on different positions. Thus these proteins forms the troponin-tropomyosin complex on the filament.The proteins exposes part of the actin molecules, as the binding site for the myosin head cross bridges between the two filaments types.
Hydrolysis of ATP supplies energy for the withdrawal of the myosin head from the actin filaments and its tilts back to the filaments to ensure contraction and relaxation of muscles muscles fibres.
Now.if glycerine created holes in the sacrolemma,Ca+ ions will be reduced,ATPs molecules hydrolysis will be also be affected,therefore, troponin-tropomyosin complex can not be formed.Thus actin filaments would not be exposed,for myosin head to bind, (therefore the myosin binding site is blocked on the actin molecules)this eventually prevent muscles contractions without the nervous transmission.
In Type I diabetes the body cannot make ______ and in Type 2 diabetes the hormone ________ doesn't work properly.
(Choose the best option.)
1. Estrogen and insulin
2. Epinephrine and insulin
3. Insulin and glucagon
4. Insulin and insulin
Answer: 4. Insulin and insulin
Explanation:
Diabetes indicates that the level of glucose, or sugar, is very high in the blood. It occurs when the pancreas doesn't produce enough insulin or when the body doesn't use insulin properly (called insulin resistance). Insuline is a hormone that helps glucose get into the cells to give them energy, and glucose comes from the food and drinks being the main source of energy. Sometimes a person has both problems. In both cases, the result is that glucose does not enter the cells and builds up in the blood.
In type 1 diabetes, the pancreas does not produce insulin, Without insulin, too much glucose stays in the blood and over time, high blood glucose levels can cause serious problems in the heart, eyes, kidneys, nerves, gums, and teeth.
With type 2 diabetes, the most common type, the body does not make or use insulin well. There is a higher risk of type 2 diabetes if the person is older, obese, have a family history of diabetes, or don't exercise. Also, having pre-diabetes also increases that risk because people who have pre-diabetes have higher than normal blood sugar but not enough to be considered diabetic.
So, in type 1 diabetes there is an absolute lack of insulin due to the destruction of the pancreatic islets. While type 2 diabetes is a metabolic disorder characterized by hyperglycemia (high blood sugar) in the context of insulin resistance.

To perform the experiment, Jared will follow these instructions: Put one or two ice cubes in one cup of water. Chill the cup of water in the refrigerator for 1 to 2 hours. Remove any remaining ice when taking the water out of the refrigerator. This cup holds the ice-cold water. Heat up three cups of water in the microwave for 15 to 20 seconds until they reach 100°F on the thermometer. If the water is too hot, wait until the temperature drops to 100°F. These cups hold the lukewarm water. Heat the last cup of water in the microwave until it reaches 212°F. This cup holds the boiling water. Line up five glasses an label them A, B, C, D, and E. Then put the following contents in ea QUESTION:What is Jared testing in this experiment? A)how the temperature of water affects photosynthesis B)how the products of anaerobic and aerobic respiration differ C)the rate at which sugar dissolves D)the amount of respiration that occurs
Answer:
A) how the temperature of water affects photosynthesis.
Explanation:
Photosynthesis is a process in which plants transform light into chemical energy. They require water and sunlight to grow. During the process light energy is absorbed by plants and they consume water, carbon dioxide and some mineral from soil to produce oxygen by a chemical reaction. Jared is also considering to analyse the different water temperatures. The higher temperature of water will enhance the rate of photosynthesis.
What happens to electrons when pigments in Photosystem II absorb light? They combine with oxygen and hydrogen to produce water. They are pumped across the membrane into the thylakoid. They move through an electron transport chain to Photosystem I. They become excited and break down the pigments to release ATP.
Answer:
The correct answer is They move through an electron transport chain to Photosystem I.
Explanation:
Luminous energy is trapped by a chlorophyll molecule in the Photosystem II. When the pigment molecules absorb light, electrons get in a higher energy level. These excited electrons go through the electron transport chain to an inferior energy level in the photosystem I. When the excited electrons leave photosystem II, they are replaced by new electrons that are extracted from the water molecules. As electrons go through the transport chain, their released energy is used to produce ATP molecules. Luminous energy absorbed in the photosystem I move the electrons to another electron acceptor from where they are transported again and used to produce NADPH molecules. When electrons are eliminated from Photosystem I, they are replaced by new electrons that are coming from the photosystem II through the transport chain.

enzymes ___ the activation energy threshold required to start a chemical reaction lower or raise
Answer:
lower
Explanation:
Enzymes are chemical substances or biological molecules that catalyze biological reactions by lowering the activation energy threshold required to start such reactions.
The activation refers to the minimum energy that must be conquered by the reactants in a chemical reaction in order to cross over to the product's side.
Enzymes work by lowering this energy and hence, making the crossing over to the product's side faster than normal. They are not themselves used up in reactions and can always be recovered and reused.
Correct answer: lower
Which correctly lists three agents that loosen and carry away rock during the erosion process?
animals,heat,sedimentheat
heat, wind, plants
plants, animals, wind
sediment, heat, plants
Answer:
Plants, animals, wind
Explanation:
I used the process of elimination. Heat and sediment cannot move dirt and/or rocks
Animal and plant movement is a factor in biological weathering. For instance, a plant may grow in a gap in a rock and, as its roots spread, cause the crack to widen. Even you have the potential to weather! Thus, option C is correct.
What loosen and carry away rock during erosion process?The dirt is kept in place by plants. Some animals scrape pebbles as they eat to weather them. Other creatures alter the surface of the Earth by digging into it and shifting stuff.
The majority of the vegetation can be destroyed by an excessive number of animals, which speeds up erosion.
Earthen materials are worn away during erosion, a geological process in which they are moved by wind or water.
Therefore, Earthen materials are worn away during erosion, a geological process in which they are moved by wind or water.

Identify internal and external factors that regulate cell division
Answer:
External factors can be cell to cell contact. Internal factors can be when the DNA is disrupted or a cell already has two of a part then will be divided.
Explanation:
Cell to cell can make a cell think it has already been divided while if DNA is disrupted it could cause nonstop growth, known as cancer.
Cells in contact with one another can be considered an external force. Internal factors can play a role in cell division, such as when the DNA of a cell is damaged or when it already contains two copies of a particular component.
What are factors regulating cell cycle?Signals that come from the outside can be either physical or chemical. Contact between individual cells is an illustration of a physical component. Once they come into contact with other cells, the vast majority of mammalian cells will cease their dividing. One example of a chemical signal would be growth factors, which are proteins that encourage cell proliferation and are also an example of chemical signals.
Internal factors such as kinases and cyclins are responsible for regulating cell division. Cyclin-dependent protein kinases are responsible for determining, once cells reach a checkpoint in the middle of the cell cycle, whether or not they will continue the process of cell division or call an end to it.
