The process of passing genetic material from one generation to the next depends completely on how cells grow and divide. To reproduce, a simple organism such as bacteria or yeast simply copies its DNA (through a process called replication) and splits in two. But organisms that reproduce sexually go through a complicated dance that includes mixing and matching strands of DNA (a process called recombination) and then reducing the amount of DNA in special sex cells to arrive at completely new genetic combinations for their offspring.
There are two basic kinds of organisms — ones with a nucleus and those without a nucleus (a compartment filled with DNA surrounded by a membrane called a nuclear envelope):
<span>Prokaryotes: Organisms whose cells lack a nucleus and therefore have DNA floating loosely in the liquid center of the cell. Prokaryotes divide, and thus reproduce, by simple mitosis.</span><span>Eukaryotes: Organisms that have a well-defined nucleus to house and protect the DNA. Eukaryotes divide by meiosis for sexual reproduction.</span>
Answer:
C. glucose
Explanation:
Dark reaction takes place outside the thalakoid membrane (stroma and cytoplasm). During dark reactions, energy is released from ATP and NADPH to fix carbon dioxide into <em><u>glucose</u></em>.
Option A and B are not correct because they are produced during light reactions. Likewise, chlorophyll is the part of cell and is not prepared during light or dark reactions at all.
A, because it the constant variable
Answer:
The correct answer is A. Since the Earth has a tilted angle of 23.5 degrees as it moves around the sun, the amount of sunlight that is received by the hemispheres vary from time to time. This is mainly responsible for the changes in the temperature and daylight hours, which are the indicators of the changes in seasons.
In this case, when one hemisphere of the Earth is tilted toward the sun, it receives more sunlight than the other end. Therefore, this region experiences summer, wherein the daylight is longer and the temperature is warmer
