Hereditary (genetic) information is stored inside what part of the cell?

Why is mass a better unit for measuring matter than weight?*

SIZIF [17.4K]

Answer:

Because mass is constant, while weight depends on gravity.

Explanation:

For example, your mass on Earth will be the same as your mass on planet Mars. Your weight however, will change depending on the force of gravity exerted on you.

joja [24]

Answer: A segment of dna/chromosome containing the instructions for building a protein which will result in a trait is called a GENE.

Explanation:

CHROMOSOMES are made up of two threads called chromatids joined at a point called the centromere.

In the chemical nature of chromosomes, each is made up of a protein framework which has a long molecule of DNA (deoxyribonucleic acid) coiled round it. A segment of DNA containing the instructions for building a protein which will result in a trait is called a GENE.

The GENES in the cell of a diploid organism contain all the necessary instructions for building up the organism.These instructions are written on a molecular scale.. Most genes contain information to direct the synthesis of specific proteins. Each such protein takes part in the development of a particular character.

A protein is made up of one or more chains of amino acids known as polypeptides. The sequence of bases in a DNA molecule determines the type of amino acid and the sequence in which they are arranged in a polypeptide chain.

A gene therefore is a sequence of triplets of the four bases which specifies the structure of a protein

If a DNA polymerase recognizes a guanine nitrogenous base on the template strand, which nitrogenous base will it polymerize to t

Klio2033 [76]

Chargaff's rules state: adenine is complimentary to thymine and cytosine is complimentary to guanine. For this question, in order for polymerization of the growing complementary strand, guanine must bind with cytosine.

Shifting biomes could have consequences for the regions in which the shifts occur. Read the two cases below and decide which con

Nata [24]

Answer:

increased risk of wildfires- both

local economy suffers- Case 1

carbon storage decreases - Case 2

agricultural production decreases - Case 1

carbon storage increases - Case 1

disease vector range changes - Case 2

decreased water availability - Case 1

local economy thrives - Case 2

species range changes - Case 2

Explanation:

Fires are common to taiga biomes. Owing to the fact that the biome in case 1 changed from an agricultural community to a grassland and subsequently to a desert, agricultural productivity will decrease, the local economy will suffer, water availability is decreased and local economy suffers as a consequence of desertification.

On the other hand, in case 2, the diseases vector range as well as species range changes due to the change in the species of foxes from Artic foxes to red foxes that carry rabies. Carbon storage decreases as the taiga biome acts as a carbon sink. The local economy thrives due to timber production.

Lastly, species range changes both in case 1 and case 2 since there is a loss of species. Species range is the area where a particular species can be found during its lifetime. Certainly, the range of area where species are found changed in cases 1 and 2.
