Solid because it maintains their shape and is rigid
in this case the answer would be letter "D"
Answer:
The mother can carry a full-term baby with A blood type because the mother's blood does not mix with the baby's blood, so the mother's immune system does not activate attacking the baby.
Explanation:
The reason why a mother with B blood type and A antibodies in her system can carry a full-term pregnancy is thanks to the placenta. The placenta is a shared organ between the mother and the baby. Its function is to protect the baby and produce the necessary exchanges of nutrients and wastes between the maternal blood and the baby's blood. As the two types of blood are separated, and they never get in contact during pregnancy, the immune system of the mother does not recognize the baby as a treat. The mother can have A antibodies in her plasma due to a previous pregnancy where during delivery, the two types of blood mixed, also it can be due to any contact with the A blood type. When the foreign blood enters the body, the immune system forms antibodies for it.
Answer:
Myelination
Explanation:
The covering of myelin around the axons is called the myelin sheath. This myelin sheath helps in transfer of information faster and also in complex processes of the brain. The process of myelination begins in the PNS (peripheral nervous system).
The myelinated section are seperated from each other with a gap called nodes of ranvier. Glial cells (oligodendrocytes) forms the myelin sheath in the central nervous system and schwann cells (glial cells) forms the myelin sheath in peripheral nervous system. The propagation of electrical impulse in the myelinated fibers is by saltatory conduction that is from one node to another.
Answer:
Organism
Explanation:
An individual palm tree grown in a tropical forest is regarded as an organism. This answer is gotten from the definition of an organism. An organism is defined as an individual living thing, which could be an animal, a plant, or a one celled creature. An individual palm tree is an organism because individually bit has all properties of life and can respond to stimulus.
Answer: 5. glycolysis, the tricarboxylic acid cycle, and oxidative phosphorylation
6. If oxygen is not present, some organisms can undergo fermentation to continually produce ATP. Glycolysis, which is the first step in all types of cellular respiration is anaerobic and does not require oxygen.
7. Glycolysis is the process in which one glucose molecule is broken down to form two molecules of pyruvic acid
