Answer:

Autonomic nervous system.

Explanation:

The human psychology involves the study of the emotions, anger and feelings of the humans with themselves and other people of the society. The emotions are controlled by the external as well as internal factors.

The peripheral nervous system of the body constitutes the autonomic nervous system. This system is activated during the stress and anxiety response. The autonomic nervous system prepares the body for the fight and flight mechanism.

Thus, the answer is autonomic nervous system.

If a hamster has 22 chromosomes in its somatic cells, how many chromosomes would it have in its gametes
amm1812
Normally a hamster has 44 chromosome in its body but since it’s cut in half which leaves it 22 chromosomes (as stated above) the answer will be 11 gametes
22 divided by 2 = 11

EXPLANATION:
The sperm of the father, when it fuses with the egg, the embryo has 22 chromosomes
To find the number of chromosomes for each gamete, divide the total number by two eggs. The egg and sperm have half of the genetic information for an embryo

Answer:

<h2>Carbon is the chemical backbone of life on Earth. Carbon compounds regulate the Earth’s temperature, make up the food that sustains us, and provide energy that fuels our global economy. </h2><h2 /><h2>The carbon cycle. </h2><h2>Most of Earth’s carbon is stored in rocks and sediments. The rest is located in the ocean, atmosphere, and in living organisms. These are the reservoirs through which carbon cycles. </h2><h2 /><h2>NOAA technicians service a buoy in the Pacific Ocean designed to provide real-time data for ocean, weather and climate prediction. </h2><h2>NOAA buoys measure carbon dioxide </h2><h2>NOAA observing buoys validate findings from NASA’s new satellite for measuring carbon dioxide </h2><h2>Listen to the podcast </h2><h2>Carbon storage and exchange </h2><h2>Carbon moves from one storage reservoir to another through a variety of mechanisms. For example, in the food chain, plants move carbon from the atmosphere into the biosphere through photosynthesis. They use energy from the sun to chemically combine carbon dioxide with hydrogen and oxygen from water to create sugar molecules. Animals that eat plants digest the sugar molecules to get energy for their bodies. Respiration, excretion, and decomposition release the carbon back into the atmosphere or soil, continuing the cycle. </h2><h2 /><h2>The ocean plays a critical role in carbon storage, as it holds about 50 times more carbon than the atmosphere. Two-way carbon exchange can occur quickly between the ocean’s surface waters and the atmosphere, but carbon may be stored for centuries at the deepest ocean depths. </h2><h2 /><h2>Rocks like limestone and fossil fuels like coal and oil are storage reservoirs that contain carbon from plants and animals that lived millions of years ago. When these organisms died, slow geologic processes trapped their carbon and transformed it into these natural resources. Processes such as erosion release this carbon back into the atmosphere very slowly, while volcanic activity can release it very quickly. Burning fossil fuels in cars or power plants is another way this carbon can be released into the atmospheric reservoir quickly.</h2>

M) anchors cytoskeleton of one cell with that of a neighboring cell. <u>Adhesive junction</u>

<u />

Explanation:

<u>Connexin:</u> is a transmembrane protein that forms the gap junctions, they are also called gap junctions proteins.

<u>Hemidesmosome junctions:</u> these types of junctions are in the epidermis, specifically between the epithelial cells and the basal lamina of the epidermis.

<u>Plaque:</u> they are part of the adherens junctions, they are fibrous proteins that are attached to certain points of the extracellular matrix.

<u>Tight junctions</u><u>:</u> are junctions between two epithelia, they are very restrictive and do not allow the passage of soluble molecules creating a permeability barrier.

<u>Desmosomes</u>: are very strong cell to cell junctions on the lateral sides of plasma membranes. They are in tissues that are under mechanical stress, such as the cardiac muscle.

<u> Connexons:</u> is a pore made of six connexin proteins in a gap junction. Connexons are the ones that connect two cells in gap junctions.

<u>Focal adhesions:</u> They connect the extracellular matrix with the cell, regulatory signs and mechanical force is transmitted through them.

<u>Tonofilaments:</u> tonofilaments are the ones that are associated with a plaque in adherens junctions, they are in epithelial tissues.

<u>Adherens junctions:</u> are cell to cell junctions where the cytoplasmatic face is connected to the actin cytoskeleton. They appear as spots forming the plaque or as zonula adherens, which are actin bands around the cell.

<u>Cell junctions </u>are protein complexes that connect two cells that are next to each other or a cell with the extracellular matrix. They have a lot of functions, such as pas information from cell to cell, or the exterior, form a barrier, synchronize cells, etc.

<u>Gap junctions:</u> are connections between the cytoplasm of two cells, molecules and, ions pass directly from one cell to the other.

Portal blood vessels connect two capillary beds found in the ________. A. hypothalamus and thalamus B. anterior pituitary and po
sdas [7]

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.
  1. Beta endorphin,
  2. prolactin,
  3. thyroid-stimulating hormone (TSH),
  4. adrenocorticotropic hormone (ACTH),
  5. growth hormone (GH),
  6. follicle-stimulating hormone (FSH), and
  7. 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.
