Both plants and animals have these. It is a eukaryotic cell.
The correct answer for this question is D - lipids. Lipids are also
known as fat, and are useful not only as protection, but also as long
term storage for energy, protection for vital organs. A certain type of
lipid even assists with communication between cells.

Pediculosis capitis also known as
the head lice infestation is the infection of the head hair and scalp by the
head louse (Pediculus humanus capitis). Head lice are spread by direct contact
with the hair of someone who is infected. Itching from lice bites is common and
may cause problems with sleeping. The itch may not develop for up to six weeks
when a person is infected. Symptoms may begin much more quickly if a person is
infected again. However, it is not a serious condition.
The three (3) measures the nurse
will inform the mother about to address the infestation of pediculosis capitis
were
<span>a. </span>Combing
the hair frequently with a fine tooth comb or shaving the head completely.
<span>b. </span>Washing
the Child’s clothing in hot water with detergents
<span>c. </span>Applying
Spinosad 0.9% topical suspension on his hair.
Answer:
The correct answer is "There are several mechanisms that explain why a hormone have different effects in different cells. These mechanisms include: multiple receptors for the same hormone, a single receptor coupled to different pathways and hormones interacting with receptors for other molecules".
Explanation:
Hormones are among the most versatile molecules of the body, responsible for different biological processes such as human growth, sex development and metabolisms. Hormones are responsible of these complex biological processes because they have drastically different effects in different cells. There are several mechanisms that explain why a hormone have different effects in different cells. These mechanisms include:
- Multiple receptors for the same hormone. For instance, there are multiple receptor for dopamine, a hormone and neurotransmitter responsible for different functions such as movement, memory, sleep and motivation.
- A single receptor coupled to different pathways. Most hormone receptors act with a cascade of signaling. This in consequence results in a single receptor interacting with different molecules having multiple effects.
- Hormones interacting with receptors for other molecules. One example is the action of one metabolite of progesterone named allopregnanolone. This metabolite interacts with GABA-A receptor, which gives it anxiolitic properties.
Answer:
Voltage describes the amount of energy associated with electric charge as it moves around in a circuit. Its standard unit, the volt, is related to the standard units of electric charge (the coulomb) and energy (the joule) such that one volt is equal to one joule of energy for each coulomb of electric charge.
