Answer:

your answer would be These external agents of genetic change are called mutagens. Exposure to mutagens often causes alterations in the molecular structure of nucleotides, ultimately causing substitutions, insertions, and deletions in the DNA sequence.

Answer:

a) 12 brown eyes

b) 12 brown hair

c) 3 Brown eyes blonde hair

d) 9 brown eyes brown hair

e) 3 blue eyes brown hair

f) 1 blue eyes blonde hair

The correct complementary DNA sequence of 3'AGGTCAGGT 5 is - D. 5' TCCAGTCCA 3'

DNA is made of two strands of DNA strands coiled together and form a ladder-like shape. DNA molecules have four nucleotide bases that joined both strands together that are Adenine (A), Guanine (G), Thymine (T), and Cytosine(C).

      So, in the given sequence:       3'AGGTCAGGT 5

     Complementary sequence:       5' TCCAGTCCA 3

Thus, the correct option is: option D. 5' TCCAGTCCA 3

Explanation:because A turns to T and G turns to C for DNA but for RNA A turns to U and vise versa

Answer:

Explanation:

The allele are fixed because there is no variation that exist in the population and the allele are almost completely the same hence no new combination of gene the same Allele will continue to reoccur

Variability exist because of random mating that occurs in the population initially when the toad filled up the entire central valley

Random mating ensures fitness in the initial population

Genetic drift acted upon the population drifting away allele that are very few in population or that occur less in the population and perpetuating alleles that frequently occur leading to a fixed allele.

There was a decrease in the population as a result of the change in the environment.

Answer:

Nucleotides

Explanation:

The nucleotides forming each DNA strand are connected by noncovalent bonds called hydrogen bonds.

Nucleotide is the unit that repeatedly joined together to form a strand of DNA.

Deoxyribose + phosphate group + thymine could be a nucleotide of DNA and defined as deoxyribonuclic acid and it is a polymer made up of two polynucleotide chains that arranged in foiled structure to form a double helix carrying genetic information for the various processes such as growth development  functioning and reproduction.

There are four nitrogen bases of DNA nucleotides are such as adinine, thymine, guanine and cytosine.

Friedrich miescher discovered DNA in the year of 1860.The shape of DNA is double helical structure

The main function of DNA is to carry information from one generation to another generation this is the reason due to which DNA is also known information molecule.

In our body DNA is found in the nucleus of the cell and it is known as nuclear DNA. The shape of DNA is double helical structure.

Siblings share only about 50% of same DNA due to the reason of recombination. The life span of DNA is 521 years.

Therefore, Nucleotide is the unit that repeatedly joined together to form a strand of DNA.

Answer:

it will compare that neither has an affect on the population and it will also compare that both will be equal to one another.Hope this helps let me know if its wrong or not have a good day.

Explanation:

It will compare that neither has an affect on the population and it will also compare that both will be equal to one another.

The term "population" refers to all citizens who are either permanently residing in a country or who are just passing through. This indicator reveals how many people typically reside in a certain area.

Growth rates are the population changes that occur each year as a result of births, deaths, and net migration.

The total population also includes national military forces deployed overseas, merchant mariners at sea, diplomatic staff based abroad, civilian foreign nationals residing in the nation, and internally displaced people residing in the nation. Demographic tools like population predictions are frequently used.

Therefore, It will compare that neither has an affect on the population and it will also compare that both will be equal to one another.

Answer:

The soil in the alpine biome is rocky and nutrient poor.  Plants that live in the alpine biome must be suited to the nutrient poor soil.

Explanation:

The plants living in the alpine biome are adapted to survive on limited nutrients as the conditions in the alpine biome is harsh and not favorable. Hence, the plants have to adapt the mountain climate.

An adaptation is any physical or behavioral feature of an organism that helps them to survive better in their environment. In other words, an adaptation is something that helps them in finding food, water, mates, and shelter.

The alpine climate is the typical climate for elevations above the tree line, where the trees fail to grow due to cold conditions. The climate of alpine biomes is also referred to as the mountain climate or highland climate.

Plants which are living in alpine biomes are typically low growing due to the extreme environmental conditions. There are only about 200 species of alpine biome plants which have adapted to life in cold temperatures and sparse rainfall.

No living beings can survive alone. There always exists a close relationship between living and non - living things. The environment of the earth consists of physical and biological factors. The physical and biological factors together constitute an ecosystem. The ecosystem may be natural or artificial , temporary or permanent. Thus, an ecosystem is an ecological unit which consists of both biotic ( living ) and abiotic ( non - living ) factors of the environment. The organisms and the environment are inseparably interrelated and interactive in their nature. A.G. Tansley ( 1935 ) , a British ecologist used the term ecosystem first.
