An intracellular signaling molecule produced by the binding of a ligand to a membrane-bound receptor is called a __________.
sammy [17]

Answer:

The intracellular molecule produced by the receptor ligand complex is called Second messenger.

Explanation:

Receptors are membrane bound proteins which bind to the ligands which are also called first messengers and cause cellular changes. These intracellular changes are mediated by second messengers such as proliferation, differentiation, migration, apoptosis, transcription, contractions etc. They are specific for specific first messengers such as homones and growth factors. They relay the signals between the ligands to their target molecules in the cytosol or nucleus. Most common second messengers are cAMP, cGMP, DAG, IP3.

Signal amplification by second messenger can be explained by the example of IP3 which cayses the release of Calcium ions from the intracellular stores and cause contractions.

Over the past 300 years, how did the role of the ocean change with respect to the amount of carbon dioxide in the atmosphere
spin [16.1K]

Answer:

Ocean plays the role of regulator.

Explanation:

The role of the ocean change with respect to the amount of carbon dioxide in the atmosphere because oceans plays a role of regulator and balancer. When there is high amount of carbon dioxide in the atmosphere due to burning of fossil fuels and volcanic eruptions so the ocean absorb that extra amount of carbon dioxide from the atmosphere while on the other hand, when there is decrease in the concentration of carbon dioxide in the atmosphere, the ocean gives its carbondioxide gas to the atmosphere to regulate the concentration.

Julio wants to study the effect of water temperature on hatching of fish eggs in a lake which these experiment designs would be
almond37 [142]

Complete Question: Julio wants to study the effect of water temperature on the hatching of fish eggs in a lake. which of these experimental designs would be most practical for julio?

a. he should put fish eggs in aquariums of lake water kept at different temperatures and observe.

b. he should build a computer model of fish eggs in a lake that has many different water temperature settings.

c. he should use cameras to observe fish hatching in the lake and temperature probes to monitor water temperature.

d. he should take water samples from lakes of different temperatures and observe for eggs and newly hatched fish.

Answer: is <em>a). he should put fish eggs in aquariums of lake water kept at different temperatures and observe. </em>

Explanation:

By viewing all four options the most accurate and near to possible is <em>option A. </em>Other three techniques are not doable and have higher chances of inaccuracy. The results fetch from other techniques will contain various error which results in wrong findings. Instead of studying and controlling whole lake water temperature, a sample of water lake should be taken and adjusted it's temperature accordingly under observation in a controlled and monitored environment. By doing so, the eggs can be monitored and observed under an adjusted temperature with full accuracy. Hence option A is more suitable and more realistic approach in finding the desired results.

A small GTP-binding protein called ______________ assembles as a ring around the neck of each deeply invaginated coated pit, pin
Gennadij [26K]

Answer:

A small GTP-binding protein called dynamin assembles as a ring around the neck of each deeply invaginated coated pit, pinch off the vesicle. After the budding is complete, the coat proteins are removed, and the naked vesicle can fuse with its target membrane.

Explanation:

Dynamin - may be a GTPase that takes part in an important role in clathrin-dependent endocytosis and other vesicular trafficking processes by acting like a couple of molecular scissors for newly setup vesicles originating from the cell wall.
