Answer:
a. Decrease water reabsorption
: decrease blood pressure.
b. Decrease peripheral resistance
: decrease blood pressure
c. Vasodilation
: decrease blood pressure
d. Decrease salt intake
: decrease blood pressure
e. Decrease blood volume
: decrease blood pressure
f. Vasoconstriction
: increase blood pressure
g. Increase peripheral resistance: increase blood pressure
h. Increase salt intake: increase blood pressure
i. Increase blood volume
: increase blood pressure
j. Increase water reabsorption: increase blood pressure
Explanation:
- Total peripheral resistance: This term refers to the resistance offered by the vascular system to the blood flow. This resistance is a result of the friction between the blood and the vessel's walls. In other words, it is the opposition of the vessels to blood flow. The total peripheral resistance is the summary of all the bloody circuit resistances in the body. Those mechanisms that induce vasoconstriction conduce to an increase in total peripheral resistance, while mechanisms that induce vasodilation provoke a decrease in total peripheral resistance.
- Blood pressure: This term refers to the strength applied by the blood against the vessel walls as it flows. This pressure is determined by the bombed blood strength and the volume as well as by the vessel size and flexibility. Blood pressure changes continuously according to the activity, temperature, diet, emotional state, among others.
- Salt ingestion causes an increase in plasmatic osmolarity, stimulates thirst, and hence, water ingestion. Sodium retains water, expanding the blood volume and causing an increase in vessel pressure.
- The antidiuretic hormone, also known as vasopressin hormone, is released by changes in serum osmolarity or blood volume. Its function is to keep homeostasis and make kidneys conserve or keep water by concentrating urine and by reducing its volume. By these actions, the antidiuretic hormone stimulates water reabsorption, according to the organism´s needs.
- Kidneys control blood pressure in many ways. If the pressure is elevated, kidneys produce the loss of salt and water, normalizing arterial pressure. But if pressure is low, kidneys conserve water.
Answer:
Seeds are the result of plant reproduction. ... When pollen lands on the flower's stigma, it germinates and forms a pollen tube, which then quickly grows towards the plant's ovary. Once it finds an ovule, the pollen tube bursts to release sperm cells, which fertilize the ovule and initiate seed formation.
Explanation:
Portal blood vessels connect two capillary beds found in the hypothalamus and anterior pituitary.
So, the correct option is C.
<h3>Hypothalamus-Pituitary Complex:</h3>
- The "command center" of the endocrine system is assumed to be the hypothalamus-pituitary complex.
- In addition to hormones that directly affect target tissues, this complex also secretes hormones that control the production and release of hormones from other glands.
- Furthermore, the hypothalamus-pituitary complex controls the communications between the nervous and endocrine systems.
- The hypothalamus-pituitary complex is frequently necessary for the translation of a stimulus into hormones that can start a reaction after it is received by the neurological system.
- Additionally, the pituitary gland (also known as the hypophysis), a bean-shaped organ hung from the hypothalamus by a stem called the infundibulum (or pituitary stalk), is physically and functionally connected to the hypothalamus.
- The sella turcica of the sphenoid bone of the skull serves as a cradle for the pituitary gland.
- It has two lobes, the posterior pituitary (also known as the neurohypophysis), which is made of neural tissue, and the anterior pituitary (also known as the adenohypophysis), which is made of glandular tissue.
<h3>Anterior Pituitary:</h3>
- The embryonic anterior pituitary develops from the gastrointestinal tract and moves toward the brain as the fetus grows.
- The pars tuberalis is a thin "tube" that wraps around the infundibulum, the pars distalis is the most anterior, and the pars intermedia is next to the posterior pituitary.
- Neurons secrete hormones from the hypothalamus, but blood arteries transport them to the anterior pituitary.
- There is a capillary bridge that links the anterior pituitary and hypothalamus inside the infundibulum.
- The hypophyseal portal system is the network that enables the delivery of hypothalamic hormones directly to the anterior pituitary without first passing via the systemic circulation.
- The superior hypophyseal artery, a branch of the carotid arteries that carries blood to the hypothalamus, serves as the system's initial point.
- The hypophyseal portal system is made up of the superior hypophyseal artery's branches.
- The portal veins deliver hypothalamic releasing and inhibitory hormones into the anterior pituitary via a main capillary plexus.
- Anterior pituitary hormones enter a secondary capillary plexus in reaction to hormones being released, and from there, drain into the blood circulation.
- In the anterior pituitary, seven hormones are produced.
- Separate hormones produced by the hypothalamus either promote or suppress the anterior pituitary's capacity to produce hormones.
- The hypophyseal portal system is the route by which hormones from the hypothalamus get to the anterior pituitary.
- Seven hormones are produced by the anterior pituitary.
- Beta endorphin,
- prolactin,
- thyroid-stimulating hormone (TSH),
- adrenocorticotropic hormone (ACTH),
- growth hormone (GH),
- follicle-stimulating hormone (FSH), and
- luteinizing hormone (LH).
- Because they regulate the activity of other endocrine glands, the anterior pituitary hormones TSH, ACTH, FSH, and LH are together known as tropic hormones.

Answer:
c. 10
Explanation:
The pH scale ranges from 0 to 14.
0 is the most acidic
7 is neutral
14 is the most alkaline
10 is near 14
true because when u move that makes u warm and if u werent moving you woud be cold
