Answer: D)
Membrane proteins produce phospholids
Explanation:
Membrane proteins in the mitochondria do more than just generate cellular energy. The proteins in the membranes of the mitochondria are complex machines in the nanoworld that mediate the oxygen-coupled generation of energy in cells. Their role in this process is not yet understood in detail.
Membrane proteins perform a variety of functions vital to the survival of organisms: Membrane receptor proteins relay signals between the cell's internal and external environments. Transport proteins move molecules and ions across the membrane.
Answer:
1. asexual, mitosis 2. sexual 3. gametes, meiosis 4. haploid 5. sex cells
Explanation:
Asexual reproduction is the form of reproduction that occurs whereby there is no fusion of gametes or a change in the number of chromosomes. The produced daughter cells are genetically similar to the parent. the form of cell division that occurs here is through a process of mitosis.
Different organisms adopt different type of asexual reproduction including binary fission, spore formation, fragmentation etc.
Sexual reproduction in contrast generates genetically unique organism through the fusion of two different organisms sex cells. To accomplish sexual reproduction, gametes that are haploid through a process of meiosis must be produced which are the egg cell and the sperm cells (the sex cells). These haploid cells are produced only in the germ cells to ensure the production of a diploid zygote.
Answer:
If limestone reacts with limestone, it can turn into a limestone. The reason behind this formation is that, both substances have the same chemical and physical properties and molecules of limestone have a strong chemical bonds between them so it is difficult to separate them from each other.
If the mutation is beneficial, the mutated organism survives to reproduce, and the mutation gets passed on to its offspring. In this way, natural selection guides the evolutionary process to incorporate only the good mutations into the species, and expunge the bad mutations.
Mees lines. These are characteristic of heavy metal poisoning.
