How is the age distribution pattern of the Hawaiian Islands - Emperor Seamount chain explained by the position of the Hawaiian hotspot? Explain using evidence and reasoning.
Answer:
Find the explanation below.
Explanation:
The Hawaiian Islands is a series of islands positioned in what looks like a chain, which increases in age as one moves northwest. The Hawaiian hotspot was formed as a result of the collision of the tectonic plates in the outer part of the earth which caused the rise of a volcano, and which in turn gave off magma which came to rest on a seafloor. That eruption on the seafloor is the hotspot.
This hotspot remains unmovable while the tectonic plates are in constant motion around the hotspot, giving rise to further Islands. This explains the age distribution pattern of the Hawaiian islands which arrived at different times making some older than the others.
The temperature of the interior of the human body is about 37oC (98.6oF), regardless of the air temperature. Explain the importance of constant body temperature given the role of enzymes as catalysts in the body.
It is critical that we sustain an optimal temperature for our body's enzymes. When it gets too hot, our enzymes denature and become inactive/lost their function. If the temperature is too low, the enzymes will become ineffective.
What is homeostasis?Homeostasis is the state of constant internal, physical, and chemical assumption is supported by living systems in biology.
This is the state of the organism's optimal functioning, and it includes many variables, such as core temperature as well as fluid balance, getting kept within certain pre-set limits.
Enzymes can only function when the body's temperature remains constant. As a result, homeostasis becomes an important part of the body's metabolism.
Homeostasis maintains optimal conditions for enzyme action and all cell functions throughout the body.
It is the preservation of a constant internal environment in the face of changing internal and external conditions. These include blood glucose concentration control in the human body.
Thus, having an optimum temperature is essential in functioning of enzymes.

what would happen to your body of blood pressure didn't work as it should?
Answer:
Vision problems. Heart attack. Stroke.
Explanation:
Answer:
Many things.
Explanation:
Blood pressure is a needed thing in a body. It gets blood to your organs and everywhere that needs it. If it didn't work, many things could happen.
Too high BP(hypertension):
If your blood pressure is too high, it can cause ruptured vessels, heart attacks, strokes, heart failure, which is where the heart enlarges too much to continue pumping blood at the adequate pressure/speed, kidney disease/failure, which would be from damage to the arteries around the kidneys, vision loss due to damage to the vessels in the eyes, angina, which is chest pain due to narrowed vessels in the chest, some forms of which may cause heart attacks.
Too low BP(hypotension):
If you're experiencing hypotension, there are many things commonly associated with it. These are dizziness, fainting, nausea, blurred/fading vision, lack of focus, and fatigue. If hypotension becomes extreme, it can cause someone to go into shock, which is life threatening and can and will cause death.

What is a lipid that makes up cell membranes and is used to create hormones?
cholesterol**
Cholesterol makes up cell membranes and is used to create hormones.
Cholesterol is a necessary lipid for the body as it contributes to the formation of cell membranes and hormones. However, high amounts of cholesterol in the blood have harmful consequences for health.
Cholesterol has different functions in the body such as:
- Formation of structures: It is one of the main components of the plasma membranes of animal cells.
- Contributes to the formation of hormones: sex hormones (progesterone, estrogens, and testosterone), corticosteroid hormones (cortisol and aldosterone).
- Contributes to the metabolization of calcium to obtain vitamin D.
Additionally, the options hydrocarbon (natural chemical compound obtained from the earth to be used as fuel), starch (natural macromolecule that contributes to the human digestion process) and glucose (the most abundant chemical compound in nature that serves as a source of energy for organisms) are not correct options, because these substances do not have the function of forming cell membranes and creating hormones.

People who have Tay-Sachs disease cannot metabolize some lipids effectively. Tay-Sachs is a recessive disorder. A student used a Punnet Square to determine the probability of offspring inheriting the disease. The results from a Punnet Square are 25% TT, 50% Tt, and 25% tt.
Which conclusion can be made regarding the phenotype of the parents based on these results?
The parents must be TT, Tt
The parents must be Tt, tt
The parents must be TT, tt
The parents must be Tt, Tt
Answer:
The parents must be Tt, Tt
Explanation:
Based on these results, we can conclude that each of the parents will have one dominant (T) and one recessive allele (t). We can prove this by drawing the Punnett square:
T t
T TT Tt
t Tt tt
We can see that the offspring will have the Tt genotype in two cases, the TT genotype in one case, and the tt genotype in one case, as well. Now we need to do some basic math. Two out of four is 50% (Tt - 50%), and one out of four is 25% (TT - 25%, tt - 25%).
This means that the parents must be Tt, Tt.

Shameeka is studying for an exam. She took the notes below about calcium and chlorine, which are known to form ionic bonds.
Calcium, which is a metal, donates 2 electrons to chlorine.
The individual calcium atoms become ions with a negative 2 charge.
The bond between calcium and chlorine makes the atoms stable.
Calcium and chlorine attract each other.
Which best describes Shameeka’s error?
Calcium is a metal, so it donates protons, not electrons.
The individual calcium atom has a positive, not negative, 2 charge.
The bond formed makes the atoms unstable, not stable.
Calcium and chlorine repel, not attract, each other.
Answer:
The individual calcium atom has a positive, not negative, 2 charge.
Explanation:
The error in her study is in the second line of her note which suggests that the individual calcium atoms becomes ions with a negative 2 charge.
When atom loses electrons, it has a net positive charge on it. Not a negative charge. This is because the number of protons is now more than electrons. Therefore, a net charge on the calcium atom will be a positive one. This is her mistake.Answer:
B) The individual calcium atom has a positive, not negative, 2 charge.

Which statement best describes what happens during translation?
Answer:
B
Explanation:
The entire process is called gene expression. In translation, messenger RNA (mRNA) is decoded in a ribosome, outside the nucleus, to produce a specific amino acid chain, or polypeptide. The polypeptide later folds into an active protein and performs its functions in the cell.
During translation, the ribosome reads the mRNA and uses the information to assemble a protein.
Translation is the second step of protein synthesis. It takes place in the ribosome, a complex structure made up of proteins and RNA. The ribosome reads the mRNA, a molecule that contains the genetic information for a protein. The mRNA is translated into a protein by a process called codon-anticodon pairing.
Codons are three-base sequences in mRNA that code for specific amino acids. Anticodons are complementary sequences in tRNA molecules that bind to specific codons. When the ribosome encounters a codon in the mRNA, it brings in the corresponding tRNA molecule. The tRNA molecule carries the amino acid that corresponds to the codon.
The amino acid is then added to the growing polypeptide chain. The ribosome continues to move down the mRNA, reading codons and adding amino acids until the entire protein is synthesized.

When a food handler can effectively remove soil from equipment using normal methods, the equipment is considered what?
Answer:
Cleanable
Explanation:
Cleanability refers to the ease with which microorganisms or particles can be removed from the equipment used in food production. To be cleanable the roughness of the machine being employed in production is not expected to exceed 0.8μm.
The Atomic Force Microscope is used to measure the surface roughness of machines. Cleanability is important as it ensures that the machines used in food production are safe.
When a food handler can effectively remove soil from an equipment by using normal methods, the equipment is considered to be; Corrosion Resistant.
The soil referred to her would be dirt because we are talking about a food handler.
Now, if the food handler is finding it difficult to remove dirt from the equipment by using normal/regular methods, it means that the soil/dirt has succeeded in having some kind of chemical reaction with that equipment.If that is the case, then it means the equipment is undergoing corrosion because corrosion is defined as the gradual destruction of a metal by chemical reaction with the environment.Since we have established that inability to use normal method denotes corrosion, then if he can use normal methods to remove the soil effectively, then the equipment is said to be corrosion resistant.Read more at; https://brainly.in/question/40223031

C. ADP loses a phosphate group which releases energy for use by the cell.
D. ADP gains a phosphate group which releases energy for use by the cell.
Answer:
B. ADP gains a phosphate group which stores energy for use by the cell.
Explanation:
ADP is converted to ATP for the storing of energy by the addition of a high-energy phosphate group. The conversion takes place in the substance between the cell membrane and the nucleus, known as the cytoplasm, or in special energy-producing structures called mitochondria.
The statement that describes how ADP is converted into ATP is as follows:
ADP gains a phosphate group which stores energy for use by the cell.Thus, the correct option is B.
What is ATP?ATP stands for Adenosine triphosphate. It may be defined as an organic compound that delivers energy to operate many processes in living cells, such as condensate dissolution, muscle contraction, nerve impulse propagation, and chemical synthesis.
ATP is considered a high-energy compound that furnishes immediate energy to the cell for metabolic activities.
ADP gets converted into ATP by gaining one phosphate group which is the most potent high-energy phosphate. This conversion of ADP to ATP generally takes place in the cytoplasm or in the membrane-bound cell organelle known as mitochondria.
