Answer: gametes are cells used to sexual reproduction. they are haploids and that means they have just one set of chromosomes (most of the cells of our body have 2 sets). that kind of cells is produced mainly by meiotic division of the gamete's stem cell (called oogonium or spermatogonium) and that's why meiosis usually leads to the production of gametes. gametes are haploids so that they could combine (egg with sperm cell) and create the whole new organism (adult organism is almost always diploid).
Explanation:
Gametes are an organism's reproductive cells. They are also referred to as sex cells. Female gametes are called ova or egg cells, and male gametes are called sperm. Gametes are haploid cells, and each cell carries only one copy of each chromosome. These make these cells different to the ones produced during mitosis
Answer:
The independent variable in the experiment is A. the jar covers.
Explanation:
The independent variable in an experiment represents the thing that the person conducting the experiment changes or alters. One group in the experiment had covers (this represents the experimental group) and the other group had no cover (this represents the control group which was not exposed to the independent variable). Since the only thing that Redi changed between the two groups was whether or not the jars were covered, this represents the independent variable.
The number of jars and the contents of the jars were constant in both experiments, and the number of maggots on the meat is the dependent variable (the result of changing the independent variable).
Hope this helps!
I believe it would be 46 chromosomes.
Please let me know if this is correct
<h2>Answer is option "B"</h2>
Explanation:
- Our brain requires an enormous measure of vitality and so as to meet this needs the progression of blood must be accurately arranged to guarantee that oxygen is being conveyed where it is required and when it is required.
- Vitality in the mind is created solely from a type of digestion that requires oxygen. However, neurons just keep up a little save of vitality and these cells require a constant inventory of oxygen, particularly when the cells are terminating and speaking with their neighbors.
- Blood dashing through a brain district's trap of vessels is an indication that nerve cells in that region have kicked vigorously. The blood races to dynamic territories to supply terminating neurons with the oxygen and glucose they require for vitality.
- Hence, the correct answer is option B "Active areas of the brain take up more oxygenated blood than they need for their energy requirements"
