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;
-They all provide water
Explanation;
In reaction A, the reactants are glucose and fructose , and the products are Sucrose and water. This is a condensation reaction, following the combination of two monosaccharides (glucose and fructose) forming a dissaccharide (sucrose) and water.
In reaction B, the reactants are two amino acids, that results to formation of a dipeptide and water; this is also a condensation reaction joining two amino acids monomers, to form a dipeptide and water.
-In reaction C, a monoglyceride combines with a fatty acid to form a diglyceride and water. This is also an example of a condensation reaction that results to formation of a diglyceride and water.
Therefore, the similarity of all the reactions is that they are all condensation reactions, with water as a common product.
Answer:
D. Cyclin
Explanation:
Cyclins drive the events of the cell cycle by partnering with a family of enzymes called the cyclin-dependent kinases (Cdks). A lone Cdk is inactive, but the binding of a cyclin activates it, making it a functional enzyme and allowing it to modify target proteins.
Since it's been crossed with a homozygous wrinkled green, the offspring has a genotype for heterozygous round and yellow. As round and yellow are dominant traits, they're expressed in the phenotype. But when self pollinated in the f2 generation, the recessive ones will show as well
Hope it helps :')
