The most appropriate advice to give Charles at this time about Caesar salad is - a. This salad will likely meet your needs of vitamins, minerals, and fiber.

A classic Caesar is one of the simplest salads out there. it is a mix of romaine lettuce, parmesan cheese, and croutons.

It has a high content of calories in comparison to the other salads.Caesar salad is well-known for being unhealthy, and that is mostly due to its dressing.If dressing is removed from it then the salad would be a better option for lunch. Without dressing it provides vitamins, fat, fiber, and minerals to the body.

will make you brainiest please help

Answers

Tertiary consumers in a food chain or food web are animals that obtain their nutrients and energy by feeding on other animals within the same food chain or web.

Tertiary consumers are usually at the top of the food chains in their ecosystem. They have the capacity to feed on animals that consume grasses directly (primary consumers) or even on animals that feed on other animals (secondary consumers).

Secondary consumers, on the other hand, are animals that feed on primary consumers. They, at the same time, serve as prey for tertiary consumers in the ecosystem.

Thus, an animal that has the capacity to be both a secondary and a tertiary consumer would have the capacity to feed on other animals as well as be hunted as food by other members of the ecosystem.

Umm...I'm not entirely sure since there isn't an image displayed prior to the question, but I think out of the options given, the animal that it both a secondary and a tertiary consumer would be the lion.

how the function of the basal cells depends on the relationship among its parts?(respiratory system )​

Answers

Answer:

Basal cells are found at the bottom of the epidermis — the outermost layer of skin. Basal cells produce new skin cells. As new skin cells are produced, they push older cells toward the skin's surface, where the old cells die and are sloughed off.

Answer:

The respiratory system works directly with the circulatory system to provide oxygen to the body. The primary function of the respiratory system is to deliver oxygen to the cells of the body's tissues and remove carbon dioxide, a cell waste product.Respiratory systems work together to circulate blood and oxygen throughout the body.The respiratory system subdivides into a conducting portion and a respiratory portion. The majority of the respiratory tree, from the nasal cavity to the bronchi, is lined by pseudostratified columnar ciliated epithelium. The bronchioles are lined by simple columnar to the cuboidal epithelium, and the alveoli possess a lining of thin squamous epithelium that allows for gas exchange.The conducting piece of the respiratory system consists of the nasal cavity, trachea, bronchi, and bronchioles. The luminal surfaces of this entire portion have a lining of ciliated pseudostratified columnar epithelium and contain goblet cells. Their role is to secrete mucus that serves as the first line of defense against incoming environmental pathogens. Cilia move the mucus-bound particulate up and away for expulsion from the body. The various types and abundance of cells are dependent on which region of the airway they are.

A 100-pound bag of makes 345 pounds of nitrogen with hydro

Fertilizers are the chemical element for improvement of productivity of plants. Here, 0-15-15 shows nitrogen 70 pounds, phosphorous 15 pounds and potassium 15 pounds.

Why to label fertilizer?

Labeling of fertilizer is to show the content of major nutrients.  They are usually labeled with three numbers i.e.,  N-P-K label, i.e., Nitrogen-Phosphorous-potassium label , such as, 0-15-15. the first number is the percentage of nitrogen, second is for phosphorus and third is for potassium.

Thus, here as per the marking, the quantity of the nutrients are: nitrogen 70 pounds, phosphorous 15 pounds and potassium 15 pounds.

Q6.2. There are many diseases that do not infect a person more than once, such as chicken pox
and measles. What is responsible for this lifetime immunity?

The innate immune response, because barriers to entering the body improve with age.

The innate immune response, because adults have more white blood cells than children.

The acquired immune response, because antibodies are developed from previous infections.

The acquired immune response, because it responds rapidly to broad classes of pathogens.

Answers

The responsible for this lifetime immunity is the acquired immune response because antibodies are developed from previous infections. The generation of antibodies is a response to these infections.

The acquired immune system eliminates pathogenic organisms and any toxic molecules they produce.

The acquired immune system has two mechanisms of action: humoral immunity and cellular immunity.

Humoral immunity, also known as antibody-mediated immunity, involves the activation of specific blood cells (B cells) and subsequent secretion of antibodies when in contact with a pathogen.

Thus, the acquired immune system develops specific antibodies as a response to infections (e.g., chickenpox and measles).

Enzyme activity generally increases as temperature increases within an enzyme’s optimal range because an increase in temperature causes an increase in molecular motion. This increase in molecular motion results in the enzyme and its substrate coming into contact with each other more often. At too high a temperature, however, the enzyme will become denatured and no longer be able to function. As the video describes, that is what happens when someone has a high fever.

What do you think happens to enzyme activity as temperature decreases outside an enzyme’s optimal range? Explain your answer in terms of molecular motion.

Answers

This most reliable temperature is commonly around human frame temperature (37.5 °C) for the enzymes in human cells. Above this temperature, the enzyme shape begins to interrupt down denature given that at better temperatures intra- and intermolecular bonds are broken because of the enzyme molecules' advantage of even greater kinetic electricity.

Each enzyme has a temperature variety in which a maximal charge of response is accomplished. This maximum is referred to as the temperature most desirable of the enzyme. The most excellent temperature for maximum enzymes is set at ninety-eight. 6 tiers Fahrenheit (37 ranges Celsius). There also are enzymes that work nicely at decreased and better temperatures.

Most activity is accomplished on the enzyme's ultimate temperature. The lively website online of the enzyme modifications shape as the temperature rises above the surest temperature, resulting in a decline in interest. Above and under the highest quality temperature, activity decreases.

Most enzyme functions are done at 37∘C in humans due to the fact the enzymes are capable of holding their structure at that temperature, allowing it to break down complex molecules efficiently.
