g. increases peripheral resistance : 1. Angiotensin II.
h. stimulated by baroreceptors in blood vessels: 2. Sympathetic Nervous System
i. stimulated by low blood pressure or volume: 3. Both
Explanation:
The antidiuretic hormone is one of the hormones released by the hypothalamus (regulator center in the brain) and collected by the posterior hypophysis from where they are then released again to the system. This hormone, also known as vasopressin hormone, is released by changes in serum osmolarity or blood pressure. The osmotic receptors are located in the hypothalamus, while the pressure receptors are located in the heart, the aorta, and carotids. The amount of hormone secreted depends on these two aspects. Its function is to keep homeostasis and make kidneys conserve or excrete water to regulate its volume. The antidiuretic hormone stimulates water reabsorption when factors such as dehydration or hemorrhages are causing an increase in blood solutes. It might also stimulate water excretion when solutes in the blood are very low or blood pressure is too high.
Aldosterone is another hormone that acts stimulating the sodium ions reabsorption. This hormone production is controlled by a circuit named the renin-angiotensin-aldosterone system. This system is activated by the decrease of blood supply to the kidney, and hence, the decrease in blood pressure and sodium concentration. These factors cause the release of the renin, a proteolytic enzyme that acts on angiotensinogen producing angiotensin I which is converted into angiotensin II. Angiotensin II is a peripheric vasoconstrictor peptide, that can increase the blood pressure when it is circulating in the plasma. It also stimulates the secretion of aldosterone.

A researcher discovers that polar bears have very good insulation and very think hair (similar to pandas). However, they do not show the rest of the panda behaviors. For example, they have high daily energy expenditure and are very active. Why are the panda and polar bear so different
Answer:
Panda and polar bear have some similar characteristics but they also have differences in their behaviors such as polar bears have high daily energy expenditure and are very active while pandas are not.
The panda and polar bear so different because of the geographical difference where they live.
Polar bears are marine mammals and live in north pole perform swimming in north oceans and also move on ice flows, where they catch seals for survival, it makes them active and energetic.
While Pandas are found in China bamboo forests and are herbivores. They eat leaves from bamboo trees, for which they do not require to be more active and get their food easily. So, Pandas are not active as polar bears.
As the climate of North pole and China is cold, both polar bear and panda have very good insulation

What are volcanoes?Molten rock and gases stored under the surface erupt through a volcano, generating a hill or mountain.
Active, inactive, or extinct volcanoes. Active volcanoes are likely to erupt again. Dormant volcanoes may erupt again. Extinct volcanoes won't erupt.Magma collects inside active volcanoes. The magma chamber's pressure forces it through rock channels and onto the planet's surface.
Volcanic eruptions can be violent or slow-moving. Volcanoes erupt through vents on the sides or a primary entrance at the top. The volcano's morphology depends on eruption rate and magma chemistry. Land and sea volcanoes exist. As lava cools and hardens, underwater volcanoes build mountains and ranges. When volcanoes rise above the ocean, they create islands.

Explanation:
Describe how protein functional groups can act as acid and base catalysts. How is it possible for a single amino acid side chain to function as both?
Answer:
By changing the transition state and pH of the medium
Explanation:
Enzymes are proteins that bind to their corresponding substrates at their active sites in order to form complexes that catalyze specific chemical reactions. A key feature of this process is the fact that both acid and base catalytic activities may be combined in the same reaction. The acceleration in the velocity of the enzymatic reaction due to the addition of acids and bases is known as acid–base catalysis, where the acid or base is not consumed during the reaction. For example, enzymes can partially transfer a proton to the medium, thus changing the transition state of the chemical reaction and also decreasing its pH.

A layer of cells called the endodermis surrounds the stele. Xylem is found towards the center of the stele and phloem towards the outside of the stele. 18) How does this compare to their arrangement in the stem? 19) The meristematic region is protected in the root by the presence of a root cap. How is the meristematic region protected in the stem tip? 20) In which of these regions would you expect to find the specialized cells of vascular tissue? 21) In which of these regions are the cells genetically identical? 22) Why?
Answer:
Epidermis layer is responsible for the protection of meristematic region.
Explanation:
Meristematic region is protected in the stem tip by epidermis which consist of dead layer of cells. Epidermis is the outer layer of stems, leaves, flowers and fruits which is responsible for the protection of inner part from damage. Vascular bundle such as phloem present near the boundary of the stem while the xylem is present in the inside of the stem. In the inside layer of the stem, all the xylem cells are genetically identical while the layer that is present at the edge of the stem is phloem in which all the cells are genetically identical to each other.
Why are G protein only found in Eukaryote cell ?
Answer:
they bind to protein-coupled transmembrane receptors with higher complexity than those found in prokaryotes
Explanation:
G-proteins are proteins found inside the cells that function as molecular switches which are activated by binding to guanosine triphosphate (GTP), while they are inactive by binding to guanosine diphosphate (GDP). The G-proteins bind to G-protein-coupled transmembrane receptors (GPCRs) in the cytoplasmic region. The GPCRs are a very diverse group of proteins that are activated by extracellular molecules ranging from small peptides to large proteins, including pheromones, neurotransmitters, light-sensitive compounds, etc, thereby allowing them to respond to diverse stimuli from the extracellular environment. In consequence, it is reasonable to suppose that the signaling pathways in which G proteins are involved have a higher complexity level than those observed in primitive prokaryotic organisms.

The pygmy shrew is the smallest mammal in North America. However, when comparing the amount of
food eaten to its body weight, the pygmy shrew eats more food than any other mammal. It will
consume two to three times its own body weight in food daily. One explanation is that the pygmy
shrew uses energy at a high rate. In fact, its heart beats over one thousand times per minute.
What is the best explanation for what happens to the food's mass and energy when it is consumed by
the pygmy shrew?
A. The mass is mostly excreted as waste. The
energy is burned up and destroyed by the
pygmy shrew's high rate of cellular respiration.
B. The mass is all used for creating new mass in
growth. The energy is stored, used in cellular
respiration, or lost to the environment as heat.
C. The mass is used for growth, stored, or excreted
as waste. The energy is stored, used in cellular
respiration, and lost to the environment as heat.
D. The mass is used for growth, stored, or excreted
as waste. The energy is burned up and
destroyed by the shrew's high rate of cellular
respiration
Answer:
C. The mass is used for growth, stored, or excreted
as waste. The energy is stored, used in cellular
respiration, and lost to the environment as heat.
Explanation:
I got it right on the quiz.
Mass used for growth, stored or excreted as waste. Energy is stored that is used in cellular respiration which is lost to the environment in the form of heat. So, the correct option is (C).
How Pygmy shrew uses its food for energy?The pygmy shrew has a large appetite which is a result of small body mass, rapid heat loss and high metabolic rate. It is kept in captivity which provides some idea of the energy requirements of the species.
The pygmy shrew has such a high metabolism that it must eat at least every 30 minutes otherwise it will die. This can be explained by food mass and energy is that due to very high metabolism most of the food mass which is rapidly used up to form shrew, and a large proportion of the food is lost from the body surface because of its very small size.
The combination of these two factors are
1. A very high metabolism which is rapidly utilizes food material, and generates large amounts of heat in a very short period of time.
2. Very small size due to which high surface area to volume ratio leading to heat loss.
Thus, Mass used for growth, stored or excreted as waste. Energy is stored that is used in cellular respiration which is lost to the environment in the form of heat. So, the correct option is (C).

If a person had not drunk any water for 8 hours before collecting a sample, would you expect his/her urine to have a high or low specific gravity? Why?
Answer:
The person’s urine will have a high specific gravity
Explanation:
A high specific gravity is characterized by an increased concentration of solutes in the urine of am individual. A low specific gravity is characterized by a low or decreased concentration of the solutes.This is usually due to dehydration as a result of environmental conditions or tedious physical activities.
This explains why a person who had not drank any water for 8 hours and is dehydrated before collecting a sample is thought to have a urine with a high specific gravity

In meiosis, each centromere has a spindle fiber attached only to one side. In mitosis, each centromere has a spindle attached to how many sides?
Answer:
In mitosis, each centromere has a spindle attached on both side of centromere
Explanation:
In mitosis, each centromere has a spindle attached on both side of centromere because Spindle fibers move chromosomes during cell division by attaching to chromosome arms and centromeres. A centromere is the specific region of a chromosome where replicates are linked together.
Spindle fibers are active in mitosis and also meiosis and they move throughout the cells and also direct chromosomes to move to where they need to move to.
Spindle fibers function in centromere in mitosis and meiosis by pulling homologous chromosomes apart after they might have been replicated to prepare for division.

In the image, the arrow Is pointing to a celestial object. Which attribute disqualifies the object from being a planet?
A. It appears to have no moons.
B. It is spherical in shape.
C. Its neighborhood is not clear.
D. It has horizontal bands on its surface.
The correct answer is C. Its neighborhood is not clear.
Explanation:
One of the key features of a planet is that it clears its neighborhood; this means the planet gravitational force is strong enough that there are no other celestial bodies on its orbit or next to it except by its moons or satellites. This does not occur in the image presented because there are smaller celestial bodies near to the main or bigger celestial body. This likely occurs if the celestial body is not big enough to clear its neighborhood, and therefore it is not a planet.
which of the following would differ if you compared the same reaction taking place with and without an enzyme
a. the chemical energy of the reactants
b. the chemical change of the product
c. the energy required to the reaction
Answer:
The correct answer is - option C.
Explanation:
Chemical energy is the energy that every substance or chemical have and its not affected by the presence or absence of the enzyme, while the activation energy is the required energy to initiate for a chemical reaction. If the energy of the chemical reaction is less than the activation energy reaction will not take place.
Presence of a enzyme lowers the amount of the energy for the initiating the reaction which is activation energy and the chemical reaction takes place.
Thus, the correct answer is - option C.
Which of the following reflects the relationship between the posterior and the anterior pituitary glands?A. Unlike the posterior pituitary, the anterior pituitary makes and releases its own hormones without input from the hypothalamus.B. One is always a little behind.C. The anterior pituitary is under the control of the hypothalamus but the posterior pituitary is not.D. Unlike the posterior pituitary, the anterior pituitary releases "releasing or inhibiting" hormones.E. The posterior pituitary releases neurohormones and the anterior pituitary releases hormones.F. They are both extensions of the hypothalamus.
Answer:
The correct answer is - option E.
Explanation:
The anterior and posterior pituitary glands are he two distinct lobes of the pituitary gland which is controlled by the hypothalamus. The anterior lobe of the master gland is receives its signals from the specific neurons of the hypothalamus known as parvocellular neurons and produces six hormones that release in to circulation by itself.
On other hand the extension of the hypothalamus or the posterior pituitary gland receives the neurohormones from the hypothalamus such as oxytocin and ADH. Neurohormones are the hormones that are released by neurons of the posterior pituitary gland.
Thus, the correct answer is option E.
