Answer:

The correct answers are option b. "replication bubbles" and d. "replication forks".

Explanation:

The nucleic acids replication systems share some similarities between eukaryotes and prokaryotes. For instance, both organism have replication bubbles. However, prokaryotes have a single replication bubble because its replication process starts from a single origin, while eukaryotes have several replication bubbles. Also, the replication forks are well conserved from prokaryotes to eukaryotes with only some differences among the enzymes present within the fork.

Triss [41]

Answer:A) Nitrogen

Explanation: nitrogen cycle ensures the movement of nutrients through the biosphere.it ensures that nitrogen is constantly reused and made available.

Nitrogen gas is available in the atmosphere but plants and animals cannot use it in that form.it must be converted to compounds such as ammonia or nitrate.

It is gotten from the atmosphere during rainfalls where it Is broken down and combines with oxygen to from nitrogen peroxide.

Nitrogen can also be fixated into ammonia by saprophytic bacteria.

Also when plants die their body tissues are broken down to form ammonia.ammonia can be oxidized into nitrates and nitrite which plants can use.

Nitrites can be released back into the atmosphere through denitrifying bacteria and the cycle continues.

inna [77]

The cell cycle involves the growth, replication, and division of a eukaryotic cell. Mitosis most directly plays a role in the division of a cell's nucleus.
Mitosis is the process that takes place in the somatic cells or the body cells, where the diploid cells divides to yield two diploid daughter cells. The process occurs in five stages which includes; interphase, prophase, metaphase, anaphase and telophase.

1. A couple of mice with brown fur and black eyes had litter with the following distribution of traits: 9 with brown fur and bla

Ierofanga [76]

Answer:

The genotype of the couple of mice is heterozygous.

Explanation:

First, we going to classify each trait as dominant or recessive allele:

Brown fur: It’s a dominant allele because 12 of 16 mice have brown fur, therefore 75% of the litter have this trait.

Black eyes: It’s a dominant allele because 12 of 16 mice have black eyes, therefore 75% of the litter have this attribute.

Grey fur: It’s a recessive allele because only 4 of 16 mice have this trait, so 25% of the litter have grey fur.

Red eyes: It’s a recessive allele because 4 of 16 mice have red eyes, so 25% of the litter show this trait.

Second, we going to name each phenotype with a letter and use a capital letter for dominant allele or a small letter for recessive allele.

For the color of the fur, let’s use letter “F”:

F: Brown fur

f: Grey fur

For the color of the eyes, let’s use letter “E”:

E: Black eyes

e: Red eyes

The genotype of each phenotype is conformed by two letters that indicates, the recessive allele is showed in the phenotype only when both letters in the genotype are small letter.

For example, for fur, there are three combinations:

FF: Brown fur (two dominant alleles)

Ff: Brown fur (A dominant allele and a recessive allele)

ff: Grey fur (Two recessive alleles)

For eyes, there are also three combinations:

EE: Black eyes (two dominant alleles) (

Ee: Black eyes (A dominant allele and a recessive allele)

ee: Red eyes (Two recessive alleles)

When both allele of the genotype are dominant or recessive, it is heterozygous, if there are a dominant allele and a recessive one, it is a homozygous.

Since there are 7 mice that show recessive phenotype, that means the genotype of the couple of mice are heterozygous. Although, both mice show a dominant phenotype, the genotype have a dominant allele and a recessive allele.

The genotype for the couple of mice is:

FfEe x FfEe

So, when we apply the Mendel's third law, we got the results showed in the chart.

The correct answer is option C) A wet spring before vegetation is growing. A lack of roots holding soils and sediments together and an over-abundance of water can result in mass movements.
