Answer:
Most cells within planarians tend to be very close to their gastrovascular cavity, in addition to their external environments. Also, planarians have the ability for oxygen and carbon dioxide to diffuse through the cells on their body walls: this makes it unnecessary for these varieties of flatworms to need a dedicated bodily system.
I think the deficiency of dedicated respiratory and circulatory systems in Planarians does not cause a problem because none of their cells are far removed from the gastrovascular cavity or from the external environment. Planarians are free-living flatworms and form the class Turbellarians in the Phylum Platyhelminthes. Flatworms have three tissue layers, that is the ectoderm, mesoderm, and endoderm.

Explanation:
Answer:
The question is incomplete, it lacks options. The options are:
A) It has made the demand for insulin decrease.
B) It has made the incidence of diabetes decrease.
C) It has made it easier for diabetics to inject themselves with insulin.
D) It has made insulin cheaper and more readily available.
The answer is D
Explanation:
Genetic engineering is a biotechnological procedure that involves the transfer of genes from one organism to another using biotechnology. In this case, bacteria cells are said to be genetically modified because their genetic content is tampered with and the genes that produces the insulin protein in humans is added into their genome. Hence, they transcribe and translate this gene to produce the protein-insulin.
Diabetic patients cannot produce this insulin in their system. Hence, the insulin produced from this genetically modified bacteria cells can be administered to diabetics via injection. This genetically modified way of producing insulin has proven to be a far better option to the previous practice of slaughtering cattles and pigs to obtain this protein because the GM method allows insulin to be produced in large amounts making it available and cheaper to diabetics.
Answer:
The human male and female reproductive cycles are controlled by the interaction of hormones from the hypothalamus and anterior pituitary with hormones from reproductive tissues and organs. In both sexes, the hypothalamus monitors and causes the release of hormones from the pituitary gland.
Well there would no longer need plants to make air or take Carbon Dioxide, and the Carbon Dioxide would me our main meal
Meiosis sexual reproduction only occurs in the gametes, which do not contribute to the body's growth and repair, only reproduction.
Replication mitosis, however, produces diploid cells identical to the parent/mother cell, which aids in the body's growth and repair.
