Answer:
Histidine
Explanation:
A heme group is a prosthetic group composed of a protoporphyrin ring and an iron (Fe) atom that binds to oxygen (O2) in hemoglobin and myoglobin. Hemoglobin (Hb) is a protein in red blood cells (erythrocytes) that carries oxygen from the lungs to the tissues, which is composed of four polypeptide chains, each with a heme group. Moreover, myoglobin is a monomeric protein located mainly in the muscles, which contains one heme group, being thus similar to hemoglobin monomers. The proximal and distal are evolutionarily conserved amino acid (histidine) residues whose names (proximal and distal) refer to their position with the iron (Fe) atom in the heme group. The proximal histidine connects the heme group with the proteins (either in monomeric myoglobin or in one subunit of Hb), whereas distal histidine contributes to stabilize these proteins while carrying O2.
When exposed to the mucous membranes on the face, biohazards can contaminate the eye as well as enter the circulation and stomach.
- Biological compounds that endanger the health of living things, particularly humans, are referred to as biohazards, sometimes known as biological hazards.
- Medical trash or samples of microorganisms, viruses, or toxins (from a biological source) that may be harmful to human health are examples of biohazards.
- Bacteria, viruses, parasites, and molds or fungi are examples of biological health risks.
- When they come into touch with skin, are eaten, or are inhaled, they can be harmful to human health.
- They have the potential to spread diseases such parasite infections, tetanus, lung infections, and food poisoning.
- The method via which a person can come into touch with a dangerous material is referred to as an exposure pathway. There are three primary exposure routes: direct touch, ingestion, and inhalation.

The correct answer is A because G and C work together, and T and A work together, except A turns into U when transferring to mRNA.
Enzyme-containing laundry detergents will remove stains more effectively than detergents without enzymes. Stains will be removed more successfully from clothing with homemade laundry detergent than from commercial detergents.
A variable that is independent is precisely what it sounds like. It is a stand-alone variable that is unaffected by the other variables you are attempting to assess. Age, for instance, could be an independent variable. A person's age won't alter as a result of other circumstances like what they eat, how much they attend school, or how much television they watch. In actuality, when attempting to establish a link between two variables, you are attempting to determine whether the independent variable affects the dependent variables in any way.
A dependent variable is precisely what it sounds like, just like an independent variable. It is something on which other elements depend. A test score, for instance, maybe a dependent variable because it could vary based on a number of variables, including how much you studied, how much sleep you got the night before the test, and even how hungry you were.

A. 1000 grams. 1000 is divided by ten each time it goes up the trophic scale. since it goes up 2, 3 and 4, the answer is 1000. (1000/10/10/10=1)
