Answer 1

Answer:

Explanation:

The most important role of lipids is the fats, phospholipids, waxes, and steroids. Lipid is a compound that contains carbon and hydrogen and is used to store energy, provide structure, and transmit information. Fats are stored in adipose tissue. Adipose tissue a group of cells that store fat, generally found under the skin and around organs.

Phospholipids are the main component of cell membranes. Waxes provide a waterproof coating on leaves and feathers. Steroids are part of cell membranes and chemical messengers in the body. It has long-term energy storage, provides insulation and protection.

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.

Where sugar concentration is high, what is the source of water taken in by phloem

Answers

let's start with the fact the the phloem of a plant is a special tissue that mainly transports food sources for the plant. one of the products it transports is various sugars - more commonly known as sap. the higher the concentration of sugars, the lower the concentration of water. in that case, the plant slows down on sugar making as it has a surplus, and once the sugars dilute within the sap and water's been taken in, the plant goes back to sugar making.

If an infectious disease can be transmitted directly from one person to another, it is a: A) Susceptible host. B) Communicable disease. C) Port of entry to a host. D) Port of exit from the reservoir.

Answers

Final Answer:

If an infectious disease can be transmitted directly from one person to another, it is a B) Communicable disease.

Explanation:

Communicable diseases are those that can be transmitted from one person to another, either directly or indirectly. These diseases are caused by infectious agents such as bacteria, viruses, or parasites. When an individual with a communicable disease comes into contact with a susceptible host, there is a potential for transmission.

The term "communicable" refers to the ability of the disease to be communicated or spread from one person to another through various means, including direct contact, respiratory droplets, bodily fluids, or other modes of transmission. Susceptible hosts are individuals who are at risk of contracting the disease when exposed to the infectious agent.

Options C and D, "Port of entry to a host" and "Port of exit from the reservoir," are related to the mechanisms of disease transmission but do not define the type of disease. The correct answer, in this case, is B) Communicable disease, as it directly addresses the nature of the disease that can be transmitted from person to person.

Answer:

B) Communicable disease

Explanation:

A communicable disease is an illness cause by a pathogen (like bacteria, virus, or parasite) that can be spread from person to person through forms of transmission, such as direct contact, sneezing/coughing, or contaminated objects. Examples of communicable diseases include the common cold and COVID-19.
