Answer:
Option A) is correct.
Explanation:
Electromagnetic waves refer to waves that are created due to vibrations between a magnetic field and an electric field.
Electromagnetic waves do not require a medium to travel through space without a medium. Electromagnetic waves can travel through air, vacuum of space and solid materials.
So,
Option A) is correct.
Answer:
Maltose is a disaccharide sugar made up of two units of glucose.
In cyclic structure, the glucose exists in two anomeric forms; alpha and beta.
These glucose units can either joined by α (1→4) glycosidic bond or by β (1→4) glycosidic bond.
Thus, the maltose exists in two anomeric form alpha and beta.
Answer:
In strict mode, the narrow-sense heritability is the proportion of the additive genetic variance that contributes to the total of the phenotypic variance. This value can be associated with the inheritance of the a-thalassemia
.
Explanation:
A-thalassemia is a genetic disorder caused by mutations affecting four different genes that encode alpha-globin, thus affecting the hemoglobin production process and, consequently, oxygen transport. The mode of inheritance of the a-thalassemia may be associated with narrow sense heritability since the phenotype is manifested by gradation, i.e., each allele might contribute in similar mode to this genetic condition.
Answer:
Different acids make different salts.
Explanation:
a hydrochloric acid
b sulphuric acid
c nitric acid
<u>Answer:</u>
Genetic disorder that can result when sister chromatids fail to separate properly is likely to occur in meta-phase (m-phase) because in mitosis during m-phase there is separation of DNA to two equal halves.
<u>Explanation:</u>
- Genetic disorder is the problem that is caused by the abnormal activities in gene.
- This is also called mutation which may cause due to error during replication of DNA and also due to some environmental factors such as radiation exposure, smokes.
- So, during meta-phase, genes might not separate and genetic disorder might happen.
