Answer:
Natural pest control
Explanation:
Because its a way to be eco friendly using natural sources which does not harm insects
Most climate scientists agree the main cause of the current global warming trend is human expansion of the "greenhouse effect"1 — warming that results when the atmosphere traps heat radiating from Earth toward space. Certain gases in the atmosphere block heat from escaping.
Based on this exert, I'd say Option C
Answer:
The correct option is c) hormonal stimuli
Explanation:
The pituitary gland, located in the anterior brain, under the hypothalamus, is formed by two lobes of very different origin. The anterior lobe or adenohypophysis, evolves as an evagination in the upper part of the mouth, from which it separates and grows towards the brain; the posterior lobe or neurohypophysis, is formed from the hypothalamus and joins the anterior lobe. The hypothalamus decides that hormones should release the pituitary by sending hormonal (hormonal stimuli) or electrical messages.
The secretion of hormones from the anterior lobe of the pituitary gland is regulated by hypothalamic stimulation factors, transported through a local blood network, the pituitary portal system. In response to hormonal stimuli of the hypothalamus, the anterior pituitary gland secretes growth hormones, the thyroid stimulating hormone (which affect the secretion of hormones from the adrenal cortex and thyroid gland respectively), the corticotropic hormone stimulates the secretion of hormones from the adrenal cortex: cortisol, which influences blood glucose levels, and aldosterone, which increases sodium retention in the kidneys, among others.
<span>The answer is </span><span>C. haploid, and are made when haploid spores undergo mitosis. </span><span>
Pollen grains are male gametophytes in plants. In pollen sacs of an anther, spore mother cells, which is diploid, undergo meiosis and form four haploid spores. These haploid spores undergo mitosis and form haploid pollen grains.
Through the process of elimination:
- Pollen grains are haploid, so choices A. and C. are eliminated.
- In ovules, female gametes are produced, not male gametes, so, choice D. is also eliminated.</span>
