2. Describe the structure of hemoglobin using the words globin, heme, & oxygen.

Answers

Answer 1

Explanation:

Each hemoglobin molecule is made up of four heme groups surrounding a globin group, forming a tetrahedral structure. ... There are four iron atoms in each molecule of hemoglobin, which accordingly can bind four atoms of oxygen. Globin consists of two linked pairs of polypeptide chains.

Answer 2
Hemoglobin, also spelled haemoglobin, iron-containing protein in the blood of many animals—in the red blood cells (erythrocytes) of vertebrates—that transports oxygen to the tissues. Hemoglobin forms an unstable reversible bond with oxygen. In the oxygenated state, it is called oxyhemoglobin and is bright red; in the reduced state, it is purplish blue. Hemoglobin develops in cells in the bone marrow that become red blood cells. When red cells die, hemoglobin is broken up: iron is salvaged, transported to the bone marrow by proteins called transferrins, and used again in the production of new red blood cells; the remainder of the hemoglobin forms the basis of bilirubin, a chemical that is excreted into the bile and gives the feces their characteristic yellow-brown colour. Each hemoglobin molecule is made up of four heme groups surrounding a globin group, forming a tetrahedral structure. Heme, which accounts for only 4 percent of the weight of the molecule, is composed of a ringlike organic compound known as a porphyrin to which an iron atom is attached. It is the iron atom that binds oxygen as the blood travels between the lungs and the tissues. There are four iron atoms in each molecule of hemoglobin, which accordingly can bind four atoms of oxygen. Globin consists of two linked pairs of polypeptide chains. Hemoglobin S is a variant form of hemoglobin that is present in persons who have sickle cell anemia, a severe hereditary form of anemia in which the cells become crescent-shaped when oxygen is lacking. The abnormal sickle-shaped cells die prematurely and may become lodged in small blood vessels, potentially obstructing the microcirculation and leading to tissue damage. The sickling trait is found mainly in people of African descent, though the disease also occurs in persons of Middle Eastern, Mediterranean, or Indian descent.

Name two disinfectants that are unsafe for salon use

Answers

Answer:

Treponema and papillidam

Explanation:

Treponema and papillidam ae unsafe to salon use.

Which are salon drugs?

Three salons were found to have unsafe amounts of formaldehyde in the air while using specified products, and OSHA cited the salon owners for failing to protect their staff from excessive formaldehyde exposure.

Additionally, OSHA cited and fined salons and other establishments (such as beauty schools) for using formaldehyde-containing or -releasing products and for not adhering to the guidelines in OSHA's formaldehyde standard (e.g., testing the air to determine formaldehyde levels, providing protective equipment, providing training).

Additionally, OSHA examined a number of items and discovered formaldehyde in them even though they were marked "formaldehyde free" or did not mention it on the label. OSHA issued citations to the producers and sellers of these goods for mislabeling the goods.

Therefore, Treponema and papillidam ae unsafe to salon use.

Which technique uses constructive feedback effectively?

giving feedback in front of a group

pointing out weaknesses first, then acknowledge the good points of a person's idea

focusing on the specific problem at hand rather than the person

focusing on what happened in the past and how to build on it

Answers

Answer:

focusing on the specific problem at hand rather than the person

Explanation:

When one receives a constructive feedback from someone, one of the ways to effectively use such feedbacks is to focus on the specific problem at hand rather than focusing on the personality of the person.

If you focus on the person, there is tendency that you might form bias that would hinder you from being objective in accepting and putting such constructive feedback into effective use.

Focusing on the person might make you discard the feedback and see it as an attack or destructive, especially if you've previously had an unpleasant encounter with the person people.

All other options given are not part of the technique that uses constructive feedback effectively.

The answer is: focusing on the specific problem at hand rather than the person

The correct answer is:

C) focusing on the specific problem at hand rather than the person

Explanation:

Answer:

I'm not sure what you're asking but here are some answers to help you:

-

All premature babies are small, require complex medical care, and may face serious complications both in the NICU and at home. A baby born 3 to 4 months early, though, will face far different complications from a baby born 1 to 2 months early.

-

By all means, let your sleeping baby sleep. Once babies learn to roll over onto their tummies, a milestone that typically happens between 4 and 6 months but can be as early as 3 months, there's usually no turning them back (especially if they prefer snoozing belly-down)
