Explain how mitosis
maintains the chromosome number of the
original cells when forming new cells.
Mitosis is a type of cell division that helps to maintain the chromosome number of the original cells by dividing cells that previously duplicate their genetic material (DNA) during the interphase (S phase).
The cell cycle is divided into the interphase and the mitotic (M) phase.The interphase of the cell cycle is in turn divided into three different phases: Growth 1 (G1) phase, Synthesis (S) phase and Growth 2 (G2) phase.During the S phase, the chromosomes (i.e., the genetic material) of a cell are duplicated.Mitosis is a type of cell division that follows the interphase of the cell cycle by which a somatic (body) cell divides to produce two genetically identical daughter cells.In conclusion, Mitosis is a type of cell division that helps to maintain the chromosome number of the original cells by dividing cells that previously duplicate their genetic material (DNA) during the interphase (S phase).

Red is dominant over yellow. If a male purebred red rose(RR) is crossed with a female hybrid rose (Rr), what percent of the roses will be red?
25%
100%
Btw i learned 50% and 75% is wrong so that is why there is only two
Answer:
100%
Explanation:
Because one of the roses is purebred dominant, all recessive genes will be overshadowed.
What is stimulus?......
Answer:
something which causes a response, a detectable change in the physical or chemical structure of an organism's internal or external environment. The ability of an organism or organ to detect external stimuli

Define what is meant by a "dominant" gene, and a "recessive" gene
Answer:
Dominant is relating to or denoting heritable characteristics which are controlled by genes that are expressed in offspring even when inherited from only one parent. Recessive is relating to or denoting heritable characteristics controlled by genes that are expressed in offspring only when inherited from both parents, i.e., when not masked by a dominant characteristic inherited from one parent

what happens to all the weight of the food we eat
Answer:
All the weight of food we eat can happen in many ways. It can be digested and turned into waste. It can also be turned into body fat. The weight of the food we eat can help give us nutrition and vitamin s.
Explanation:
The weight of food can slightly go away due to food going in to the digestion system and turns into waste.

List and define the four main elements of the water cycle.
(SCIENCE)
Answer:
There are four main stages in the water cycle. They are evaporation, condensation, precipitation and collection
Explanation:
Evaporation- Is the the process in which water changes from a liquid to a gas or vapor.
Condensation- Is the process in which water vapor or gas in the air is changed into a liquid. Is the opposite of evaporation.
Precipitation- Precipitation is water from clouds in the form of rain, freezing rain, sleet, snow, or hail.
Collection- This is when water that falls from the clouds as rain, snow, hail or sleet, collects in the oceans, rivers, lakes, streams. Also some will soak into the ground and will collect as ground water.

Calcium, IP3, and cyclic AMP are all small molecules that can be found inside most cells, yet they are known to be important second messengers that can increase or decrease in response to a wide variety of signals. However, each signal often produces completely different responses. Give an example of this phenomenon, and explain how such responses occur.
Answer:
they are second messenger molecules capable of triggering different signaling pathways
Explanation:
Second messenger molecules are intracellular signaling molecules that trigger different cellular responses. Examples of second messengers include Calcium ions (Ca2+), Inositol trisphosphate (IP3), and cyclic AMP (cAMP). Secondary messengers may be activated by different cellular responses, for example, cyclases that synthesize cAMP or by opening calcium ion (Ca2+) channels. For example, cAMP signaling is able to activate kinase enzymes that perform phosphorylation and interact with other effector molecules to mediate different biological functions (for example, regulation of glycogen and sugar metabolism). On the other hand, Ca2+ signaling is required for muscle contraction, neurotransmitter release, etc. Ca2+ signaling is known to exert allosteric control over enzymes and other types of proteins.

Explanation:
Fire detecting Scanner is a system which has the ability to scan the area and tells the changes occurs in the fire inside the earth crust. This scanner collect all information about the area on the basis of which we can take steps to avoid the damage caused by the fire. With the help of this scanner we can tell that which part is safe and which part of the area is dangerous for people.
