The statement 'the immune system must attack the body's own cells' makes viral infections difficult to defeat.

<h3>What is an infection?</h3>

Infection is a type of harm that the organism suffers when pathogenic microorganisms and viruses enter the body.

Pathogenic microorganisms include, for example, bacteria, fungi, and virus entities.

These pathogenic microorganisms/entities have specific antigens which can be recognized by the immune system.

Which of the following statements best describes the role of adenylyl cyclase in the epinephrine signaling pathway?
Nesterboy [21]

Answer:

It accelerates the production of a second messenger.

Explanation:

Adenylyl cyclase is an enzyme capable of converting ATP molecules into cyclic adenosine monophosphate AMP (cAMP). The cAMP molecule is considered to be a second messenger that transfers the hormonal signal (i.e., epinephrine) inside the cell. Subsequently, cAMP activates molecular signaling events by binding and thus activating cAMP-dependent protein kinase A (PKA). Finally, this last protein (PKA) phosphorylates different proteins that control many diverse cellular processes.

77julia77 [94]

Answer;

-Birth rate

Explanation;

-The birth rate is the total number of live births per 1,000 in a population in a year or period. For example; in one year, 35 giraffes are born to a population.

-A population is defined as a group of individuals of the same species living and interbreeding within a given area. Members of a population often rely on the same resources, are subject to similar environmental constraints, and depend on the availability of other members to persist over time. Scientists study a population by examining how individuals in that population interact with each other and how the population as a whole interacts with its environment.

An oxygen molecule can easily cross a plasma membrane while sodium (Na+) ions are unable to cross the membrane without assistanc
NemiM [27]

Answer:

The hydrophobic core of the membrane does not allow the charged particles to pass through it.

Explanation:

The inner core of the membrane is made up of hydrophobic fatty acid tails of phospholipids. Due to this, some substances such as large, charged and polar particles cannot cross the membrane. This is why Na+ with a positive charge cross the membrane with the help of transport proteins only. On the other hand, molecular oxygen (O2) has a small structure and does not carry any charge. Therefore, it can cross the membrane without any help of transport proteins.
