Answer:
the global average surface temperature has increased over the 20th century by about 0.6 degrees C
In the last thousand years, solar activities have caused a decrease in temperature in the northern hemisphere.
We can arrive at this answer because:
The changes in the sun were very important for the rise in temperatures during the 1000's to the 1100's.However, over the years this activity and changes in solar production caused this temperature to drop, especially in the northern hemisphere.Even though this decrease in temperature was something small and subtle, in the last thousand years it has been established in the region above the equator.This process explains how global warming was not the result of changes in solar production, as this change caused a cooling. In this case, this confirms that global warming was caused by the accumulation of greenhouse gases caused by human actions.

For traits controlled by a single genetic locus, dominant phenotypes are expected to occur at a frequency of approximately 75%, in a randomly mating population.
true or false and why
Answers
Answer:
True.
Explanation:
The dominant phenotypes are expected to occur at a frequency of approximately 75%, in a population because of its dominant nature which allows them to appear in the physical structure of the organisms. In most of the offspring, the dominant allele shows their characteristics in the population whereas the recessive allele are hidden in that organisms and we can't see them in the physical appearance of the organisms.

The opening and closing of the heart valves is caused by Multiple Choice action potentials within the cusps of the valves. pressure changes of alternating contraction and relaxation during the cardiac cycle. contraction and relaxation of papillary muscles that pull on heart strings. contraction of the smooth muscle in the walls of the great vessels leaving the heart.
Answers
Answer:
pressure changes of alternating contraction and relaxation during the cardiac cycle.
Explanation:
In Human anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.
Generally, the cardiac cycle occurs in two (2) stages;
I. Diastole : in this stage, the ventricles is relaxed and would be filled with blood.
II. Systole: at this stage, the muscles contracts and thus, allow blood to be pushed through the atria.
Hence, the opening and closing of the heart valves is caused by pressure changes of alternating contraction and relaxation during the cardiac cycle.

A marine biologist measured the amount of heat radiated from an aquarium over the course of an experiment. His measurements are shown in the graph below.
Graph shows heat, measured in Joules, radiated from an aquarium over time, measured in seconds. At 0 seconds, the energy, in the form of heat, is 1.2 Joules. At 5 seconds, the energy is 1.6 Joules. At 10 seconds, the energy is 1.3 Joules. Finally at 15 seconds, the energy is 1.5 Joules.
Based on this data, he concludes that the aquarium cannot be considered a closed system for this experiment. Explain why this conclusion is invalid.
A closed system exchanges both matter and energy with its surroundings, and the scientist only measured the exchange of heat.
A closed system can exchange energy but not matter with its surroundings, and the scientist did not measure the movement of matter.
A closed system exchanges all of its energy with its surroundings, and the scientist only measured the exchange of heat.
A closed system exchanges all of its matter with its surroundings, and the scientist did not measure the movement of matter.
Answers
Answer:
The correct answer is - A closed system exchanges all of its energy with its surroundings, and the scientist only measured the exchange of heat.
Explanation:
The amount of heat radiated is measured and analyzed by the marine biologist in this given experiment from an aquarium and on the basis of data the diagram is represented that states that the radiated energy is not constant over time and there are fluctuations.
It can not be considered as a closed system as energy is still exchange with the surrounding system, however, mass is not exchange but still, it cannot be called a closed system.

Answers
Answer: d. All the body cells arise from mitotic divisions of the same fertilized egg.
Explanation:
After conception occurs and an egg is fertilized, mitosis takes place as the egg begins to divide into other cells. This is how all the cells in the body are eventually formed regardless of how specialized their roles are.
As a result, every cell in the human body shares the same genes so any biological liquid or structure of the body would indicate the criminal because they would share the same gene as the rest of the cells in the criminal.

Why are enzymes important for our bodies
Answers
Answer:
Because enzymes have many functions as chemical catalysts in numerous chemical reactions (for example in metabolism). By lowering the activation energy, they make it much easier to carry out reactions. They are also indispensable for signal transduction and cell regulation, often via kinases and phosphatases. They also generate movement, with myosin hydrolyzing ATP to generate muscle contraction, and also transport cargo around the cell as part of the cytoskeleton. Other ATPases in the cell membrane are ion pumps involved in active transport.

The reaction would continue to proceed through the path of x
Answers
Answer: The reaction originally proceeded through the path of y but now proceeds through the path of X is the answer
Explanation:
Since the enzyme works based on a lock and key model, the reaction will continue through path X (the path of the uncatalyzed reaction).
An enzyme is a biological catalysts that promotes many biochemical reactions in the body. Enzymes are specific. Only a given enzyme can catalyze a particular reaction.
Owing to the fact that enzymes function based on a lock and key model, When active site of an enzyme is damaged, it can no longer fit into its substrate hence, the reaction will continue through path X.
