Answer:
A cell cycle is a series of events that takes place in a cell as it grows and divides. A cell spends most of its time in what is called interphase, and during this time it grows, replicates its chromosomes, and prepares for cell division.
Explanation:
hope this is what you meant :)
The mutation in the somatic cells is known as somatic mutations. As they do not take place in the cells, which give rise to gametes, thus, the mutation is not inherited to the next generation by the sexual means.
On the other hand, the genetic mutations take place in the germline cells, that is, egg and sperm, because of this the mutations possesses the tendency to get passed on from one generation to another.
Thus, mutations are only passed on to offspring when they take place in germ cell DNA. The other kind of cells, the somatic cells refers to the rest of the cells in the body and mutations, which takes place in these cells do not get inherited further to the offspring.
Hence, the correct statements are mutations to gametes can be passed on to an organism's offspring and mutations to somatic cells are only present in the type of cell in which the mutation occurred.
Answer:
Of the many important reasons to worry about the thousands of fires raging in the world’s largest rainforest, oxygen supply is not one of them.

Answer: The colour of A before the starch test is GREEN while after the starch test is BLUE- BLACK. The equation for photosynthesis is
6CO2 + 6H2O → C6H12O6 + 6O2.
Explanation:
PHOTOSYNTHESIS is the process by which green plants use energy from sunlight to manufacture their own food. It is a building up process since simple inorganic compounds such as carbondioxide and water are built up into large organic compounds such as glucose and OXYGEN is given off as a by product.
Oxygen given out in photosynthesis occurs in the light stage during the process of photolysis of water. This occurs when the chlorophyll traps, absorbs and captures light energy and become energised. The energised chlorophyll supplies energy which is to split molecules of water into hydrogen ion ( H+) and hydroxyl ion ( OH-). The hydroxyl ion is reconverted to water and oxygen is given out as a by product.
To show that chlorophyll is NECESSARY for photosynthesis, a variegated leaf with green and yellow patches is used for an experiment.
The green portion is marked A and the yellow portion marked B. The leaf is tested for starch using the procedure below:
--> place leaf in boiling water for half a minute to kill it.
--> decolorize leaf by placing it in hot alcohol.
--> dip decolorize leaf in hot water to soften it.
--> place leaf on tile and add iodine solution to it.
RESULT: It would be found that only the green parts contain starch as blue+black colouration is observed while yellow area is unaffected by iodine.
Answer:
1.Sea urchins are powerful primary consumers in the kelp forest. 2. Kelp is the producer in the kelp forests. 3. Bat star are omnivores and scavengers and at the end of the food web are tertiary consumers. 4 Phytoplankton are primary producers. 5. Zooplankton is a primary consumer in the food web.
Explanation:
1.Sea urchins are powerful primary consumer in the kelp forest because they are needed to keep the kelp anchored to the bottom of the ocean and algae . 2. Kelp is the producer in the kelp forest kelp forests provides an ecosystem for many organisms from the sea floor to the surface and provides shelter for many forms of sea life. 3. As a scavenger bat star is important in the ecosystem helping clean dead animals, and algae from the seafloor, the bat star keeps the seafloor healthy. 4. Phytoplankton are accounted for about half of photosynthesis on the planet, which makes them an important producer of oxygen, and serves as food source for smaller sea organisms, they consume carbon dioxide that would otherwise dissolve in the sea water making it more acidic. 5. Zooplankton are the animal like primary consumers of plankton community they also provide the base for the entire food web also if plankton disappeared it would increase the levels of carbon in our air.
