Answer:
Cell division is a process that makes our skin, tissues, muscles, sex cells. It is the building block of our body.
Explanation:
When parents cells ahs been divided into two or more than two daughter cells then it is called division of cells. The division of cells occur as a larger cell. When we talk about eukaryotic cells, these cells divided into two distinct types of the cells, the vegetative cells.
The daughter cells are the identical to the parents cells genetically. There are two types of division such as mitosis and meiosis. When parents cells divides in daughter cells and daughter cells divided further, this process called the cells cycle. The mitosis cell division occur interphase. Meiosis cell division occur in two phase meiosis I and meiosis II.
In What phase of meiosis does Chromosomal reduction occur?

When measuring the brightness of a star, what is a limitation of using apparent magnitude rather than absolute brightness?
Apparent magnitude does not use the star's color or temperature.
Apparent magnitude is only theoretical, thus its value cannot be directly measured with equipment.
Apparent magnitude does not take into account the fact that not all stars are the same distance from Earth.
Apparent magnitude is only on a comparative scale that determines how bright a star looks from a theoretical distance of 32 light-years from Earth.
Answer:
D. Apparent magnitude is only on a comparative scale that determines how bright a star looks from a theoretical distance of 32 light-years from Earth.

Why is DNA locked in the nucleus of the cell ?
Answer:
Inside the nucleus lies the blueprint that dictates everything a cell will do and all of the products it will make. This information is stored within DNA. The nucleus sends “commands” to the cell via molecular messengers that translate the information from DNA.

Explanation:
Pepsin is an enzyme produced in the stomach. Pepsin has an optimum pH that is very acidic, between a pH of 1.0 and 2.0. In an
experiment involving the enzyme pepsin, the pH is raised from 2 to 11. What will be the MOST LIKELY effect of this on the reaction?
Explanation:
the pepsin enzyme will not be able to work in a basic medium when ph raised from 2 to 11 it's efficiency will be affected and will not be in a condition of digesting protein .
plz mark my answer as brainlist plzzzz.
hope this will be helpful to you .
When the pH is raised from 2 to 11 the most likely effect on the reaction is ;
The rate of reaction will decrease/delayed
Given that Pepsin enzyme has an optimum pH of 1.0 to 2.0, it will perform efficiently as a catalyst in an experiment whose pH levels fall within the range of the optimum pH of Pepsin.
Pepsin enzyme accelerates the digestion of proteins therefore when the pH levels are raised above 2.0 the efficiency of Pepsin enzyme will be negatively affected and the digestion of protein will require a higher activation energy.
Hence we can conclude that When the pH is raised from 2 to 11 the most likely effect on the reaction is The rate of reaction will decrease/delayed.

Which choice describes a strategy used to help restore cod populations?
limit the size of fishing fleets and catches
restrict fishing to trawling nets
allow fishermen to harvest from protected areas when necessary
harvest only very young fish
Answer: Limit the size of fishing fleets and catch size.
Explanation: Cod are nearly extinct therefore we either need to stop catching them or limit the amount you catch
The choice describes a strategy used to help restore cod populations is limiting the size of fishing fleets and catches. The correct option is A.
What are cod populations?Atlantic cod, a fish that was essential to New England's economy, is being fished at historically low levels, and New England cod appears to be recovering from overfishing after many years.
Many people are concerned about eating fish because the IUCN has recently classified species including cod, haddock, and grouper as endangered. The fish that are linked to high bycatch rates are another worry for divers. Animals like dolphins and turtles are accidentally killed in the nets at this location.
Therefore, the correct option is A. limit the size of fishing fleets and catches.

Answer:
Options A , C , E
Hope it helps!!
Smooth muscle is one of the three types of muscles involved in controlling the movements inside your body organs and is involuntary. Thus, options a and e are correct.
What are smooth muscles?Smooth muscles are the non-striated muscle that lacks sarcomeres and striations and thus lacks bands. They are found through the internal body structures and have a variety of functions.
The smooth muscles can be found in the walls of the liver, intestines, pancreas, urinary tract, uterus, etc. but not in the heart. They also have a spindle shape that contains only one nucleus in it.
They are not under the control of the organisms and rather are controlled by the nervous system, skeletal system, chemicals, and hormones.
Therefore, the smooth muscles are involuntary muscles that control the internal structure. Options a and e are correct.

Answer:
I would prefer to have city water because you don't have to worry about it getting polluted unlike well water. The city water is maintained by the city while with the well water, you maintain it yourself. Even though it can be pricey, most people live in the city anyway, so there is easier access to it.
Explanation:
Answer:
Well Water
Explanation:
I would prefer well water, because city water had a lot of chemicals, and city water filters out minerals that are good for the body. Also, well water tastes ten times fresher than city water. Also, well water is easy to obtain if you already have a well, all you have to do is wither pump it up, or use a basket to scoop some out.
