Answer:
b) They are produced only by organs called endocrine organs.
Explanation:
Hypothalamus can be defined as a small portion of the mammalian brain responsible for the secretion of hormones through the stimulation of the pituitary gland.
It is located between the midbrain and the thalamus. Also, hypothalamus is the most inferior portion in the diencephalon of the forebrain.
Basically, hypothalamus is the most important portion of the brain in vertebrates that controls various bodily functions.
An endocrine system refers to a series of ductless glands and organs responsible for the production and secretion of hormones that are used by the body for the performance of various functions such as metabolism, controlling growth, reproduction, mood, sleep, etc. These hormones are secreted directly into the circulatory system (blood) and then transported to the organs and tissues in the body.
The following statements about hormones are correct;
I. Glands saddled with the responsibility of producing hormones are ductless glands i.e directly secreting hormones into the bloodstream.
II. Hormones are either soluble in water or insoluble in water.
III. Hormones are often responsible for maintaining steady-state conditions in the body of a living organism through homeostasis.
IV. Hormones are typically able to turn genes off or on.
Describe the components of a buffer and the role each
plays in helping maintain a constant pH.
The components of a buffer and the role each plays in helping maintain a constant pH are acid-base and its salt.
What is a buffer?
A weak acid and its conjugate base, or a weak base and its conjugate acid, make form a buffer solution. When strong acids or bases are added, the pH balance of the two components remains stable.
A buffer is a solution that withstands any pH change when a little amount of both an acid and a base is added to it. The salt of the acid or base must be present for a solution to qualify as a buffer.
For an acidic buffer, acid and its salt with a strong or weak base are necessary ingredients. As an illustration, consider an acetic acid and sodium acetate solution.
For a basic buffer, a base salt with a strong or weak acid is a necessary component.
Thus, the components of a buffer are acid, base, and salts.

Answer:
the CORRECT answer is internet
Explanation:
Suppose you travel to a tropical place like the Bahamas and watch the coastal poikilotherms, such as fish, crabs, and starfish, swim and crawl about in the warm waters. Suppose then that you travel to northern Maine and watch the related species of poikilotherms in the cold waters there. It would not be unreasonable to expect to see the animals in Maine moving about in slow motion compared to those in the Bahamas. In fact, however, rates of locomotion are likely to look to your eye to be more similar than different in the two places. Design experiments to assess whether the Maine animals are especially able to be active in cold waters. If you find that they are, how might their high ability for activity in cold waters be explained
Answer:
The correct answer is -
exposure of the opposite environments to the species and see if they are able to be active in cold waters.
If they are then species of organism in Maine and could have more ice-nucleating agents which are responsible for their high ability for activity in cold waters.
Explanation:
To test the assess if the Maine species of organisms are especially able to be active in cold waters an experiment can be designed where one needs to place the species or animals from Maine and Bahamas in reverse conditions.
Maine animals are placed in warm water environments and species from the Bahamas can be placed in cold water. Finding if they are able to adapt in reverse condition by calculating various processes and motion, if yes then it shows that it is not a special ability to survive in cold temps. However, if it is not then the Maine poikilotherms are specially designed for their environment. In case of yes then species of organism in Maine and could have more ice-nucleating agents

What family of KBOs does Orcus belong to?
Answer:
Pluto
Explanation:
Orcus is a plutino, a trans-Neptunian object that is locked in a 2:3 resonance with the ice giant Neptune, making two revolutions around the sun to every three of Neptunes. This is much as pluto, except that the phase of Orcus's orbit is opposite from Pluto's: Orcus is at aphelion when pluto is at aphelion when Pluto is at perihelion and vice versa. This was a major consideration in selecting its name, as deity Orcus was the Etruscan equivalent of the Roman Pluto, and later becamean alternate name for Pluto
Family of KBOs orcuas belongs to plutino, it is a plutino object revolves around the sun.
What is Family of KBOs?Orcus is a plutino, a trans-Neptunian object that revolves about the sun twice as often as Neptune and is locked in a 2:3 resonance with it.
This is quite similar to Pluto, but Orcus's orbital phase is the opposite of Pluto's, Orcus is at aphelion while Pluto is at perihelion, and vice versa.
This was a key factor in naming it since the deity Orcus was the Etruscan counterpart to the Roman Pluto and eventually developed into a different name for Pluto.
Therefore, revolves around the sun twice as often as Neptune is the plutino is a orcus in the family of KBOs.

Energy is released during chemical reactions that occur in
Answer:
Mitochondria
Explanation:
Living organisms, no matter how microscopic, require energy for their metabolic activities. However, this energy is released for use in form of ATP when the organism undergo the process of cellular respiration, a metabolic process that breaks down food to release its stored energy.
However, this cellular respiration is a chemical reaction that takes place in an organelle of an eukaryotic cell called MITOCHONDRION (plu- mitochondria).

AMP-PNP is the abbreviation for a structural analogue of ATP in which the second and third phosphate groups are linked by an NH group (instead of an oxygen atom). AMP- PNP can bind to the ATP-binding site of most ATPases. It differs from ATP in that the
terminal phosphate cannot be removed by hydrolysis (so you cannot create ADP, therefore, you cannot get energy from AMP-PNP). Based on this information, explain the following
a. When isolated myofibrils are placed in a flask containing Ca2+ and AMP-PNP, contraction is quickly arrested. Where in the contraction cycle will contraction stop? Be specific.
b. What affects would you predict for cilia on a paramecium to which AMP-PNP is added? Be specific as to the proteins / molecules whose function would be inhibited and what would be the overall affect?
c. When researchers incubated purified vesicles, axoplasm (containing motor proteins), and MT from the giant squid axon and added AMP-PNP, the vesicles did not move along the MT. Explain this observation using specific proteins / processes affected.
Answer:
Explanation:
a.
Actin and myosin, two contractile proteins, make up myofibrils. ATPase activity is present in the myosin head. Troponin tropomyosin complex is displaced by calcium ions, exposing myosin's entire surrounding binding site on actin. Myosin heads execute the power stroke, and detachment of the head is needed for the second cycle. Myosin head detachment is aided by ATP binding & hydrolysis. Since the solution contains AMP-PNP instead of ATP, myosin heads are unable to hydrolyze and detach from myosin-binding sites on actin, thereby preventing contraction.
b.
The active ATPase correlated with both the dynein arms is found in cilia and flagella. Dynein is a motion motor protein family that walks around microtubules. The core of cilia is made up of microtubule bundles linked to the motor protein dynein. In the presence of AMP-PNP, the net reaction will be to stop the ciliary movement by inhibiting dynein motor proteins.
c.
Kinesins and Dyneins, two groups of motion motor proteins with ATPase activity, are involved in axonal transportation. All the motion motor proteins use energy from ATP hydrolysis to transfer secretory vesicles through microtubules. Since the inclusion of AMP-PNP does not supply electricity, vesicular transport does not occur.
