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.
The allele that can mask the presence of another allele is called dominant. The allele that is masked is recessive and if both alleles can be detected in the phenotype, then they are codominant. If they produce an intermediate phenotype like pink instead of red or white, then they have a relationship of incomplete dominance.
The correct answer of the given question above would be the term NEOPLASM. Based on the given scenario above wherein your uncle has a stem cell treatment in which he has skin cells injected into his lungs and it resulted in a benign tumor, this is called a neoplasm. Hope this answer helps.
Answer:
yes
Explanation:
Compounds: are pure substances that are made up of more than l type of atom and can be broken down or decomposed into its individual elements by chemical methods, but cannot be separated by physical methods. The ratio of the elements in a compound are always constant. (Water is always 11 % Hydrogen and 89 % oxygen).
The nutrients from the soil is taken up by the roots
to be distributed to the entire plant. The plant absorbs the nutrients into its
cells and utilized by the leaves, stem, trunk. They are also used to grow
flowers and to bare fruits.
Moreover, the nutrients are divided into two groups;
first the macronutrients which is needed by the plants in large amount such as
nitrogen, phosphorus, potassium, calcium, magnesium and sulfur. Second group is
the micronutrients, needed in tiny amounts that include zinc, copper,
manganese, boron, iron, sodium and cobalt. These two groups are essential for
normal plant growth and development.
