Gametes
When a cell divides by way of mitosis, it produces two clones of itself, each with the same number of chromosomes. When a cell divides by way of meiosis, it produces four cells, called gametes. Gametes are more commonly called sperm in males and eggs in females.
Answers:
It is how oxygen and carbon dioxide travel across the cell membrane
Molecules travel with the concentration gradient
Explanation:
In simple diffusion, molecules move from an area of high concentration to area of low concentration until equilibrium is achieved. This occurs randomly unlike in facilitated diffusion where this flow is regulated through channels by facilitators. Nonetheless, these molecules still travel down the concentration gradient, similar to simple difussion.
Answer: Active transport
Explanation:
In this type of transport, energy is required. This is especially because, in endocytosis and exocytosis, the membrane has to form some structure (some form of a vessicle) to facilitate these transport modes. This requires energy from ATP. More so, usually transport in this case is against concentration gradient.
Answer:
Osmosis.
Explanation:
Osmosis is the movement of water from a lower concentrated solution to a higher concentrated solution through a semi-permeable membrane. In this case, the cell membrane has pores that allow only water molecules to pass through but the solute molecules are too large to pass through. Therefore only water is moving down its concentration gradient.
Answer: chemical biodiversity
Explanation:
Biodiversity is the variety or variability of the life forms existing on earth. It can be measured at chemical, genetic, ecosystem and species levels. The biodiversity is maximum near the equator. The distribution of biodiversity on earth is uneven.
The chemical biodiversity can be the most important for finding the new types of the medications. As the chemical biodiversity will include the diversity of plant and animals which can be used to extract the chemicals that can be used for producing the medicinal formulations.
<span>The likelyhood that Queen Victoria and Prince Albert would have two females who were affected with the royal disease is 6.25%. The Royal disease, also known as Hemophilia, is a recessive x chromosome disorder that is sex linked. Queen Victoria was unaffected but did carry the hemophilia gene.</span>
Answer:
"Chlorine" is the element which is likely to gain electrons in a chemical bond.
Explanation:
In chlorine there are seven electrons in the valence shell, it requires one more electron so that it will become full valence and the electron will achieve the stability. For chlorine it will be easier to gain one electron and become stable than to loss all the seven electrons present in it to become stable. Also the non metals gain electrons and becomes negatively charged ions later known as the anions.
