D - the theory of natural selection states that the population will be narrowed as "less fit" organisms die and "more fit" organisms survive, passing on their beneficial genes to offspring. Therefore, more organisms are born than can survive.
The reaction which connects monomers (polymerization) is dehydration synthesis.
The name tells you about the nature of the reaction - dehydration means 'loss of water', correct? When two biological monomers connect, one gives up a hydrogen ion (H+), and the other gives up a hydroxyl group; (OH-). They combine to form H2O - water.
Answer:
a. IAIB
Explanation:
The possible genotype which is gained is IAIB. According to the blood group chart, if the female has A+ blood group and she marry with the man with blood group B, so the children which is produced from them has A, B, AB or O blood groups. So the genotype which is made from the combination of these different blood types male and female is IAIB.
Energy is transferred from the earth's surface and the atmosphere via conduction, convection, and radiation. Conduction is the process by which heat energy is transmitted through contact with neighboring molecules
Answer:
Sperm have a well-protected head and a motor to help them travel.
Explanation:
Gametes are sexual cells. Organisms make use of gametes to sexually reproduce themselves. Male organisms produce gametes called SPERM while feale organisms produce gametes called EGG. Although both of these gametes function to sexually reproduce the organism that produces them, they have different morphological characteristics that supports their physiological function.
- The sperm cell is made up of two major parts namely: the head and the tail. The head of the sperm cell contains the nucleus, which houses the genetic material of the cell i.e. DNA. For this reason, the head is well protected. Also, the sperm contains a tail region, which is actually a flagellum that enables it to be motile i.e swim through the female reproductive part. The flagellum contains a structure called AXONEME, which is referred to as the MOTOR of the sperm cell.
