The reason why it is difficult to create rules, regulations and laws to protect sea turtles over their entire range is that, it would take a concerted effort on a global scale to achieve that. The logistics and administration of such efforts of would take some years to work out.
Explanation:
Sea turtles can be found around the world. The efforts described above, therefore, would require that many different countries and cultures would have to cooperate as well as own their share of the responsibility required to make it so.
Legislation with regard to the efforts would need to be executed if not simultaneously, at least over approximately the same block of time.
Not only that, it would require tons of research as the peculiarity of each geographical location would be considered.

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.

Which of the following statements is correct?
a) Insulin suppresses the activity of glycogen synthase
b) Insulin mediates glucose uptake in the brain
c) "Prediabetes" is a condition characterized by an increased risk for the future development of type 2 diabetes
d) The rise in insulin concentration after meal ingestion is reduced in type 1 but not in type 2 diabetes
Answer:
C) Prediabetes is a condition characterized by an increased risk for the future development of type 2 diabetes.
Explanation:
Prediabetes is a condition where there's a higher than normal blood sugar level but not high enough to be classified as type 2 diabetes. It is most likely to progress to type 2 diabetes if there are no lifestyle changes to mitigate the risk.
This progression can be stopped if the necessary lifestyle changes such as physical exercise, eating a healthy diet, weight control etc, are implemented.
Prediabetes doesn't usually present with any signs and symptoms though one possible sign is the darkening of the skin on the neck, armpit and elbows.
When signs like frequent urination, excessive thirst and fatigue are noticed, it is most likely the onset of type 2 diabetes.

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.

Which activity is part of managing water resources
studying water to see whether it is polites
taking a long hot bath to say warm
drinking water and using it for swimming and boating
transporting water to areas where it is needed
Answer:
The correct answer is - transporting water to areas where it is needed
Explanation:
Water Resources Management (WRM) is the way toward developing, planning, and managing water assets, as far as both water amount and quality, over all water uses.
Water resources management is a significant issue from different retrospectives, for example, improvement of water bodies for future, assurance of accessible water bodies from contamination and over exploitation.
Water management can be done through storage in dams; redirecting water from overabundance zones to shortage zones through waterways linking; falsely recharging ground water; desalinating ocean water; towing chunks of ice from the Antarctic to water shortage locales; controlling contamination and recovering dirtied water through reusing; and cloud seeding.
Thus, the correct answer is - transporting water to areas where it is needed.
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.
During which eon did oxygen begin to build up the most in Earth’s atmosphere? a.)Phanerozoic b.)Proterozoic c.)Hadean d.)Archean
Answer:
b) Proterozoic eon
Proterozoic builds an oxygen layer in the earth's atmosphere.
What is a Proterozoic zone?The Archean Eon, the oldest of the two Precambrian periods, is older than the Proterozoic Eon. The Paleoproterozoic (2.5 billion to 1.6 billion years ago), and Mesoproterozoic (1.6 billion to 1 billion years ago).
All of the continents' recognized proterozoic rocks are significant sources of metallic ores, including iron, gold, copper, uranium, and nickel. The atmosphere and oceans underwent substantial alteration during the Proterozoic.
The fossilized remains of bacteria, blue-green algae, and the first oxygen-dependent organisms,the the Ediacarana fauna, may all be found in the Proterozoic rocks.
Therefore, Proterozoic builds an oxygen layer in the earth's atmosphere.

loss of contact inhibition
Explanation:
From the different options provided the one that is associated with the development of cancer is loss of contact inhibition. Contact Inhibition is a process of arresting cell growth when the cells come in contact with each other causing them to stop proliferating when they form a monolayer. Loss of contact inhibition would allow cells to continue replicating which leads to cancer.
Hair of the axilla can be considered what
Answer:
A. Determinate
B. Indeterminate
The answer is Determinate hair
Explanation:
Hair of the axilla which is also referred to as axillary hair is found under the arm.
A hair is referred to as being determinate if it is being replaced from time to time as a result of it getting old and wearing out.
The underarm hair is an example of the type of hair which undergoes the determinate type of growth process.
Indeterminate hair growth such as the one on the scalp continues to grow continuously and rarely wears out.
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.

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.

When DNA is replicated, the two strands are first separated through _________; each strand then becomes a _________ against which two new strands are made.
Answer:
Answered below
Explanation:
Deoxyribonucleic acid, DNA, replication is the process whereby DNA makes a copy of itself and it occurs during cell division.
When DNA is replicated, the two strands are first separated through unzipping at the origin of the replication fork. This is catalysed by the enzyme helicase. Helicase breaks down the hydrogen bonds which hold the complementary base pairs of DNA together.
Each strand of DNA to then becomes a template against which two new strands are made. One of the strands is called the leading strand and the other is called the lagging strand. Both are oriented in opposite directions.
