The property that allows large organisms like the blue whale to swim in the ocean an not be crushed by their body weight is density. If the whale has a higher density than water, it will submerge in the water.
Answer:
1. Efficiency
2. Kinetic energy
3. Pulley
4. Screw
5. Wedge
Explanation:
1. Efficiency: the ratio of work output to work input or the ratio of actual mechanical advantage (AMA) to ideal mechanical advantage (IMA).
Mathematically, the efficiency of a machine is given by the formula;
2. Kinetic energy: the energy of a moving object. Kinetic energy (KE) is an energy possessed by an object or body due to its motion.
Mathematically, kinetic energy is given by the formula;

Where;
K.E represents kinetic energy measured in Joules.
M represents mass measured in kilograms.
V represents velocity measured in metres per seconds square.
3. Pulley: a grooved wheel over which a rope can move. It is made up of a wheel and rope which allows force to be multiplied such as in a drawing well.
4. Screw: a double-sided inclined plane. It is held in position and then used to tighten two or more objects together.
5. Wedge: an inclined plane wrapped around a cylinder. It can be used to split objects into halves.
The frequency of the disorder in the population is 0.000081, So, the percentage of heterozygous carriers would be 0.018.
Unlike homozygous, being heterozygous means you have two different alleles. You inherited a different version from each parent. In a heterozygous genotype, the dominant allele overrules the recessive one. Therefore, the dominant trait will be expressed. The recessive trait won't show, but you're still a carrier.
The presence of two different alleles at a particular gene locus. A heterozygous genotype may include one normal allele and one mutated allele or two different mutated alleles.
The Hardy-Weinberg equation is given by :
⇒ p² + 2pq + q² = 1
Here, p and q represent the individual allele frequencies.
Therefore, p² = frequency of homozygous condition represented by p.
q² = frequency of homozygous alleles represented by q.
and 2pq = frequency of heterozygous condition.
So, the correct answer is '2pq'.
⇒ (aa) q² = 0.000081,
⇒ (a) q = 0.009,
⇒ (A) p = 0.991,
⇒ (Aa) 2pq,
⇒ 0.018.

Answer:
C. The diameter of a wire
Explanation:
A micrometer screw gauge is a device used for the measurement of small dimensions which may not be measured accurately by the use of a vernier caliper, e.g diameter of a thin wire. it has a high degree of accuracy.
From the given option in the question, the measurement that can be made using a micrometer screw gauge is the diameter of a wire
