Many different species of songbirds migrate into the United States and Canada from Central and South America each summer in order to take advantage of the caterpillars and other insects that hatch in the northern forests during the summer. Over the past several decades songbird populations have been declining. How might a decrease in the number of songbirds be expected to affect the trees in a northern forest?

Answers

Answer 1

Answer: The main way in which a decrease in the number of songbirds might be expected to affect the trees in a northern forest is that the would be overrun with more instincts due to a lack or predators.

Answer 2

Answer:

The trees in the northern hemisphere will be very negatively effected by the declining numbers of the migrating songbirds.

The reason for that is that the songbirds are the predators of the caterpillars. With the declining number of the songbirds, the caterpillars will grow in numbers.

The caterpillars are feeding on the leaves of the trees. As the numbers of the caterpillars grow, they will eat more and more leaves from the trees, thus making huge problems for the trees because they will not be able to properly perform the photosynthesis which is crucial for their survival. The trees will start to get diseased and lot of forests in the Northern Hemisphere will be destroyed.

Individuals with HIV/AIDS are viewed and treated the same as uninfected individuals in society. Please select the best answer from the choices provided.a. True
b. False

Answers

Answer:

False

Explanation:

People suffering from HIV/AIDS face taboos as they are considered as someone suffering from a non treatable disease which may spread if they are in contact with the affected person. Though there are several awareness campaign, which are run (by government, private agencies/NGOs) just to make people aware that this disease is not communicable but yet people consider it as communicable disease. Hence, some one who is having HIV/AIDS is not at all treated as an uninfected individual in society.

Hence, the given statement is false.

False because many of the time people are uninformed and are scared.

Histamine is a chemical substance released in inflammatory and allergic responses. The histamine H1 receptor on target cells is a G protein-coupled receptor that activates phospholipase C in response to the binding of histamine. Which statements are true about the binding of histamine to the histamine H1 receptor? Select all that apply. Histamine diffuses across the plasma membrane to bind to the H1 receptor. Histamine binds extracellularly to the H1 receptor. When histamine binds to the H1 receptor, the receptor undergoes a conformation change and binds the inactive G protein. Histamine binds intracellularly to the inactive G protein, activating the G protein. Once the G protein is active, it binds to the enzyme phospholipase C, activating it. Histamine is likely hydrophilic.

Answers

The statements 'histamine binds extracellularly to the H1 receptor', 'when histamine binds to the H1 receptor, the receptor undergoes a conformation change and binds the inactive G protein', 'once the G protein is active, it binds to the enzyme phospholipase C, activating it', and 'histamine is likely hydrophilic' are TRUE.

Histamine is a molecule released during inflammatory and allergic responses.

This molecule (histamine) binds to the G-protein coupled histamine (H1) receptor. This binding triggers a conformational change in the three-dimensional (3D) shape of the G-protein coupled H1 receptor.

Subsequently, the heterodimeric G protein is activated by GTP binding. The G-protein–GTP complex then dissociates from the G-protein coupled H1 receptor and interacts with phospholipase C, thereby activating a transduction signaling pathway.

Finally, the G protein accelerates the hydrolysis of GTP to GDP and thus terminates the transduced signal.

In conclusion, the statements 'histamine binds extracellularly to the H1 receptor', 'when histamine binds to the H1 receptor, the receptor undergoes a conformation change and binds the inactive G protein', 'once the G protein is active, it binds to the enzyme phospholipase C, activating it', and 'histamine is likely hydrophilic' are TRUE.

Answer:

-Histamine binds extracellularly to the H1 receptor.

-When histamine binds to the H1 receptor. the receptor undergoes a conformation change and binds the inactive G protein.

-Once the G protein is active, it binds to the enzyme phospholipase C, activating it.

-Histamine is likely hydrophilic.

When histamine encounters a target cell, it binds extracellularly to the H1 receptor, causing a change in the shape of the receptor. This change in shape allows the G protein to bind to the H1 receptor, causing a GTP molecule to displace a GDP molecule and activating the G protein. The active G protein dissociates from the H1 receptor and binds to the enzyme phospholipase C, activating it. The active phospholipase C triggers a cellular response. The G protein then functions as a GTPase and hydrolyzes the GTP to GDP. The G protein dissociates from the enzyme and is inactive again and ready for reuse.

In which of the following ways might the effects of a mutation in a skin cell be different from those of a mutation in a sperm cell?Sperm cell mutations are more likely to get corrected since meiosis has two phases, while skin cell mutations have only the single phase of mitosis in which to be corrected. A mutated sperm cell will always be destroyed during meiosis before it leaves the testes, while skin mutations remain within the skin. There is little chance that a sperm mutation will affect the testes, while skin mutations almost always develop into cancer. The mutation in the sperm cell could be passed on to offspring, while the skin cell mutation could only affect the individual.
