The formation of the cell plate takes place during the mitotic phase. In this description we will briefly describe all phases of the cell cycle to paint a complete picture, but feel free to skip to the section labeled “mitotic phase” to get a play-by-play on how the cell plate forms.
The NH3 molecular geometry (molecular shape) is trigonal pyramidal. The NH3 bond angles are 107 degrees because the hydrogen atoms are repelled by the lone pair of electrons on the Nitrogen atom.
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)
