Epinephrine is a hormone that regulates cellular energy metabolism to break down glycogen into glucose. The signal transduction pathway involves the production of cAMP. If caffeine blocks the activity of cAMP, what would happen to the signal transduction pathway?
The signaling pathway will amplify and produce more glucose.
The signaling pathway will conform to bind to the receptor cells.
The downstream components will be altered and ultimately affect production of glucose.
The downstream components will function normally.
Answer: The downstream components will be altered and ultimately affect production of glucose.
Explanation: Epinephrine is a hormone that belongs to a class of biomolecules called catecholamines. When it reaches the target cell it binds to a receptor that is connected to an enzyme called adenylate cyclase that converts ATP into cAMP(cyclic adenosine monophosphate). cAMP plays an important role in the phosphorylation of proteins which alters their activity. In this case the activity of the enzyme that hydrolyses glycogen to glucose. When caffeine blocks the activity of cAMP it ultimately inhibits the action of the downstream components.
If caffeine blocks the activity of cAMP, then in the signal transduction pathway the downstream components will be altered and ultimately affect the production of glucose. Thus, the correct option is C.

Carbon dioxide is used by plants for why
Answer: they use carbon dioxide to help them grow.
Explanation:
Answer:
In a process called “photosynthesis,” plants use the energy in sunlight to convert CO2 and water to sugar and oxygen. The plants use the sugar for food—food that we use, too, when we eat plants or animals that have eaten plants — and they release the oxygen into the atmosphere.

Which best explains how nutrients, salt, sediment and pollutants get into estuaries and oceans?
A. from rivers and streams flowing into estuaries and oceans
B. from organisms living and dying in estuaries and oceans
C. from asteroids and comets impacting Earth at estuaries and oceans
D. from precipitation falling over the estuaries and oceans
Rivers take nutrients, salts, sediments, and pollutants from their source at high altitudes, to estuaries and oceans, where they end. The correct option is A. from rivers and streams flowing into estuaries and oceans.
-----------------------------
A river is composed of three main courses:
The highest course ⇒ near the source.
The medium course
There is a low slope. There is a decrease in the speed of the waters, the erosive effect, and the dragging capacity. The flow increases due to the contribution of tributaries. The valley widens.The low course
It is near the mouth, where the slope is low, and the river speed decreases notoriously. There are wider valleys -plains- and wide meanders. The most characteristic feature of this part of the river is the deposit of the last materials that have been uprooted and transported in the previous phases. Hight sedimentation degree.So, from their source at different latitudes and altitudes, rivers go through different states and, as they do so, they carry with their wildlife, sediments, suspended elements, available nutrients, and dissolved oxygen, among others.
As streams pass near farmlands, cities, factories, they also carry pollutant elements, such as chemicals, microbeads, plastics, etcetera.
These elements characterize by their durability in time and resistance, which means that once in the river, they end up in the oceans, where they remain for centuries.
According to this explanation, the option that best explains how nutrients, salt, sediment and pollutants get into estuaries and oceans is option A. from rivers and streams flowing into estuaries and oceans.

A patient is given antihistamines due to an allergic reaction where vascular permeability is increased, causing watery eyes. Which of the following describes how antihistamines affect a signal transduction pathway?
Antihistamines block histamine from binding to the appropriate receptor.
Antihistamines reduce histamine in the blood by binding to and destroying it.
Antihistamines reduce the amount of histamine in the bloodstream by binding to and inactivating histamine.
Antihistamines produce a second messenger that interrupts and reverses the direction of the signaling pathway.
Answer:
Antihistamines affect a signal transduction pathway by blocking histamine from binding to the appropriate receptor (First option).
Explanation:
Antihistamines are a group of drugs used in allergic reactions mediated by the immune system. Specifically, antihistamines are competitive inhibitors of histamine binding to its specific receptor, the histamine H1 receptor.
Histamine is an inflammatory mediator, being one of the substances of the humoral immune response. It is secreted by mast cells and is responsible for the production of allergic effects, such as nasal congestion, sneezing, skin rash, and red, watery eyes. Antihistamines block histamine from binding to the appropriate receptor, preventing these effects.
The other options are not correct, because they do not correspond to the effects of antihistamines, that is, it does not bind to histamine, destroy it or render it inactive..
