______________ is a statistical procedure that can be used to identify clusters of behaviors that are related to a trait.
Mamont248 [21]

Answer:

Factor  Analysis

Explanation:

Factor Analysis is a statistical procedure that can be used to identify clusters of behaviors (such as verbal skills, intelligence) that are related to a trait.

Factor analysis helps to accumulate a lot of data in many variables into a few variables which can be used for further analysis or study. The aim of factor analysis is to aggregate individual behaviors into a minimized number of factors.

What is the minimum pH difference such that transfer of one H ion across the membrane would provide enough energy to make one mo
Studentka2010 [4]

Answer:

The minimum difference is already the value of 1

Explanation:

When the pH is not balanced between the extracellular and intracellular environment, the cell could go into shock, that is why in the face of the minimal differences in pH between the internal or external environment, the proton pump is activated, this is how the hydrogen ion or positively charged protons cross the membrane and indirectly generate ATP molecules.

I nee help brinlist i will give it to you
Montano1993 [528]

Answer:

A

Explanation:

The energy carried by electromagnetic waves is sometimes referred to as radiant energy. Electromagnetic waves do not require a medium for propagation hence they can travel through vacuum and are known to transmit enormous amount of energy.

Electromagnetic waves transmit energy away from the source of the wave. Hence the answer chosen in the answer section above.

In sickle-cell disease, as a result of a single amino acid change, the hemoglobin tetramers associate with each other and assemb
Phoenix [80]

Answer:

One of the common genetic disorders is sickle cell anemia, in which 2 recessive alleles must meet to allow for destruction and alteration in the morphology of red blood cells. This usually leads to loss of proper binding of oxygen to hemoglobin and curved, sickle-shaped erythrocytes. The mutation causing this disease occurs in the 6th codon of the HBB gene encoding the hemoglobin subunit β (β-globin), a protein, serving as an integral part of the adult hemoglobin A (HbA), which is a heterotetramer of 2 α chains and 2 β chains that is responsible for binding to the oxygen in the blood. This mutation changes a charged glutamic acid to a hydrophobic valine residue and disrupts the tertiary structure and stability of the hemoglobin molecule. Since in the field of protein intrinsic disorder, charged and polar residues are typically considered as disorder promoting, in opposite to the order-promoting non-polar hydrophobic residues, in this study we attempted to answer a question if intrinsic disorder might have a role in the pathogenesis of sickle cell anemia. To this end, several disorder predictors were utilized to evaluate the presence of intrinsically disordered regions in all subunits of human hemoglobin: α, β, δ, ε, ζ, γ1, and γ2. Then, structural analysis was completed by using the SWISS-MODEL Repository to visualize the outputs of the disorder predictors. Finally, Uniprot STRING and D2P2 were used to determine biochemical interactome and protein partners for each hemoglobin subunit along with analyzing their posttranslational modifications. All these properties were used to determine any differences between the 6 different types of subunits of hemoglobin and to correlate the mutation leading to sickle cell anemia with intrinsic disorder propensity.
