ACTH's principal function is to stimulate the cortex (outer layer) of the adrenal glands (located near the kidneys) to secrete a group of steroid hormones called glucocorticoids. Glucocorticoid hormones control the body's use of sugar and also help regulate biological functions during stressful moments
Answer:
CENTROMERE
Explanation:
The CENTROMERE is the primary constriction region where the identical DNA molecules are most tightly bonded to each other during mitosis and meiosis.
The typical chromosome in metaphase is composed of two sister chromatids joined by the centromere.
Surrounding the centromere, we can find the kinetochores. These are laminar proteinic structures forming a plate where the spindle and kinetochore fibers will join during chromatids separation.
The position of the centromere defines the chromosomes as acrocentric, metacentric, or submetacentric.

suffering from an accumulation of blood in the pleural cavity. this condition
is known as hemothorax. It is <span>characterized by
pleural fluid hematocrit values greater than 50% of peripheral blood. The main
causes are trauma, iatrogenic factors, malignancy, anticoagulation therapy,
pulmonary infarction, and aortic rupture.</span></span>
Answer:
The correct answer would be "The plant is a fern, and sporophyte is its dominant phase".
Ferns refer to the lower plants which do not bear flowers, have leafy or feathery fronds, and they reproduce by spores.
They show alternation of generation in which sporophyte is the dominant stage.
The mature diploid sporophyte releases haploid spores with the help of meiotic divisions.
The haploid spore divides by mitotic division and matures into a haploid gametophyte. The single gametophyte bears antheridium and archegonium which release flagellated male gametes and egg (female gamete) respectively with the help of mitotic division.
The gametes fertilize to produce a diploid zygote.
The zygote divides mitotically and matures into the diploid sporophyte.
Answer:
Circulatory system
Explanation:
From the right atrium through the tricuspid valve to the right ventricle through the pulmonary sigmoid valve to the pulmonary trunk to the right and left lungs to the capillary beds of the pulmonary veins to the left atrium to the left ventricle of the heart through the mitral valve, to the aorta through the aortic semilunar valve, to the whole body, to the systemic arteries, to the capillaries of the body tissues, to the systemic veins, to the superior cava vein and inferior cava vein, which enter the right atrium of the heart.
