5 0

Answer:

3 materials

Explanation:

The jacket and trousers worn by a firefighter have to be constructed from materials that will withstand intense heat. Aramid fiber is a synthetic fiber that is highly regarded for its strength and heat resistance. Nomex is the trade name for arimid fiber clothing, and this type of material is used in the construction of a firefighter jacket and trousers. Nomex is often combined with Kevlar to increase the strength of the material.

Earth is the largest terrestrial planet in the solar system. Earth's huge size enables it to exert enough gravitational force to
denpristay [2]

Answer:

Lower gravitational force due to lower mass.

Explanation:

Mars has lower gravitational force than Earth because of its lower size because mass has a direct effect on gravitational force of an object. Earth has mass of 5.972 × 10^24 kg which is 10 times greater than mass of Mars which is 6.4171 x 10^23 kg. So due to earth's more mass, it has more gravitational force than planet Mars which has lower mass than earth.

In a study of genetic variation of the Graceland gene, a researcher finds that there are two alleles in a population. In a large
Licemer1 [7]

Answer:

Option 1, No. The highest frequency of heterozygotes under Hardy-Weinberg equilibrium is 0.5

Explanation:

As per Hardy Weinberg’s equilibrium principle, the maximum frequency of heterozytotic individuals occur only when half of the population is dominant and recessive homozygous.  

In other way when the sum of frequency of dominant and recessive species is equal to 0.5, only then the frequency of heterozygotes is maximum which in any case would not be higher than 0.5.  

Hence, option 1 is correct

Hemophilia is a sex-linked disorder that is caused by a defective gene on the X chromosome. What will be the pattern of inherita
MrRa [10]
Hemophilia is considered a sex-linked recessive disorder which means the disease does not occur if only one gene in a pair is abnormal.

Inheritance pattern of the offspring of a father who has hemophilia and a mother who does not have hemophilia and is not a carrier:
- all sons will be born normal
- all daughters will be carriers

Inheritance pattern of the offspring of a father who has hemophilia and a mother who is a carrier:
- 25% chance of having a hemophiliac son
- 25% chance of having a son with no hemophilia
- 25% chance of having a daughter who is a carrier
- 25% chance of having a hemophiliac daughter
