Answer:
The correct answer is letter D. Conventional breeding
Explanation:
In conventional genetic improvement a plant is crossed with another of the same species, with no incorporation of genes from another organism into the plant's genome, requiring repeated crossings until reaching the desired improved cultivar. Only in transgenics or genetic engineering are genes from another organism incorporated into the plant's genome.

Answer: b. anterior.
Explanation:
Hypothalamic releasing and inhibiting hormones control the release of other hormones from the pituitary gland and they are secreted by neurons. They enter the anterior pituitary through blood vessels and to do this, <u>there is a bridge of capillaries that connects the hypothalamus, which is a part of the brain, to the anterior pituitary gland</u> and it is called the hypophyseal portal system. This system allows the hypothalamic hormones to be transported to the anterior pituitary without entering the systemic circulation.
So, the secretion of the hormones from the pituitary gland is regulated by releasing and inhibiting hormones from the hypothalamus. The six hormones produced by the anterior pituitary gland are:
- luteinizing hormone (LH)
- follicle-stimulating hormone (FSH)
- thyroid-stimulating hormone (TSH)
- adrenocorticotropic hormone (ACTH)
- prolactin (PRL)
- growth hormone (GH)
The endosymbiotic theory is described that the the primitive eukaryotic cell has ingested a prokaryote to become the mitochondria and the chloroplast. The mitochondria is actually a primitive prokaryote capable of performing cellular respiration. According to this theory, the mitochondria (coming from a primitive prokaryote) must have two membranes, an inner membrane and an outer membrane.
<em>Chloroplasts also have two cell membranes. </em>
The only thing the cancers have in common is that they started from a breast tissue cell. They can be different cells that may have different genetic changes.
