Mitosis and meiosis are cell division mechanisms that lead to different numbers of daughter cells. Which explanation best describes how these two processes maintain continuity?
meiosis :cell division that produces reproductive cells in sexually reproducing organisms
mitosis:cell division in which nucleus divides into nuclei containing the same number of chromosomes
meiosis nucleus divides twice and produces 4 daughter cells which are not genetically the same
mitosis necleus divides ones and produces two daughter cells which are genetically the same
1. A customer from a previous season comes into your store confused. A
bed of pink four o'clock flowers she planted the previous season self-
seeded and produced a mixture of about 1/4 red, 1/4 white, and 1/2 pink
flowers this year. The customer wants to know why the pink flowers are
now a mix of colors. This is possible because of ...
*
Answer:
The genes in flowers vary and change every season a little bit if they are not the perfect "pink" or "red" seed gene they will vary.
Hope this helps :)
Tabitha built a computer model of a weather system. She included information about bodies of water, the Sun, and the atmosphere.
After running the model the first time, Tabitha doubled the size of a freshwater lake in her model. This change caused more moderate temperatures and an increase in precipitation in the locations nearby.
Which two spheres are interacting when a body of water affects the weather of a location as it did in Tabitha's model?
a. atmosphere and geosphere
b. hydrosphere and atmosphere
c. geosphere and hydrosphere
d. hydrosphere and biosphere

Why are enzymes important for our bodies
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 active site of an enzyme is damaged, leaving it nonfunctional.
How would this change to the enzyme's function be best described using the graph above?
Choose 1 answer.
The reaction originally proceeded through the path of Y, but now proceeds through the path of
Х.
B
The reaction would continue to proceed through the path of Y.
The reaction originally proceeded through the path of X, but now proceeds through the path
of Y
The reaction would continue to proceed through the path of x
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.

b.
All the body cells of the same individual have same receptors on their surface.
Ο Ο Ο Ο
C.
All the body cells are controlled by checkpoints.
d.
All the body cells arise from mitotic divisions of the same fertilized egg.
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.
What is ment by adaptation?
Answer:
Adaptation means a physical feature or behaviour that suits plants and animals to their environment.

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.
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.
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.
