The theory of evolution is a shortened form of the term “theory of evolution by natural selection,” which was proposed by Charles Darwin and Alfred Russel Wallace in the nineteenth century
The action or process of fertilizing an egg, female animal, or plant, involving the fusion of male and female gametes to form a zygote. The gametes that participate in fertilisation of plants are the sperm (male), and the egg cell, and in flowering plants a second fertilisation event involves another sperm cell and the central cell which is a second female gamete. In flowering plants there are two sperm from each pollen grain.
Answer:
there are two ATP molecules
Answer:
A phospholipid
a. has both polar and nonpolar regions.
Explanation:
Phospholipids, as amphipathic molecules, consist of a glycerol molecule, two fatty acids, and a phosphate group that is modified by an alcohol. The phosphate group is the negatively-charged hydrophilic (water-loving) polar head, which face outward and are attracted to the intracellular and extracellular fluid. The fatty acids are the uncharged, hydrophobic (water-fearing) nonpolar tails, which face the inside, away from the water and meet in the inner region of the membrane.
Answer:
Lambdoid suture
Explanation:
The parietal bones are two bones, located above the temporal, behind the frontal and in front of the occipital. The occipital is an odd bone of the skull, with important cranial joints and sutures. The lambdoid suture extends through the back of the head. Each parietal bone joins the occipital bone in the lambdoid suture, that is, the lambdoid suture is the joint in the back of the skull that connects the parietal bones with the occipital bone.
