Proposed mode of DNA replication where one daughter cells gets both strands of parent DNA and the other daughter cell gets both
Vera_Pavlovna [14]

Answer:

c. Conservative replication

Explanation:

  • In conservative mode of replication, the parent DNA molecule will direct the synthesis of entirely new DNA molecule. Hence, one daughter cell will get the old  DNA with both parental strands and the other daughter cell will get the new DNA with both new strands.
  • But the widely accepted replication model is semi conservative model. Where both the strands separate and act as template for new strands. Hence, the new DNA molecules will have one parental DNA strand and one new DNA strand.
  • According to dispersive replication model, the newly synthesized DNA randomly gets fragments of parental DNA.

Hence, the answer is conservative replication.

Match the following terms and definitions. 1. alternative form for a specific gene (either dominant or recessive) hybrid 2. can
galben [10]

The answers would be:

1. Allele - alternative form for a specific gene (either dominant or recessive)

2. Dominant - can prevent the allele from being expressed in a pair of genes

3. Genotype - the genes present in an organism

4. Heterozygous - it is a pair of non-identical genes that influence a trait in different ways.

5. Homozygous - a pair of genes that are identical in the way they influence a trait.

6. Hybrid - offspring from a cross between parents; has different phenotypes for a specific trait.

Here's a little bit more on the topic to help you out in the future:

Alleles are variant forms of genes. Each allele is found in a specific location of a chromosome and that location determines the trait that will be expressed.

There are two types of alleles: Dominant alleles and Recessive alleles.

A dominant allele is expressed physically while a recessive allele is the trait that is masked. If both alleles are present, the dominant allele usually masks the recessive allele. This phenomenon is called <u>complete dominance</u>. There are some traits where both alleles are equally expressed, which is called <u>co-dominance. </u>

Genotype is the set of genes present in an organism that is responsible for specific traits. Phenotype on the other hand is the physical expression of the trait, which depends on the genotype of the organism.

Alleles come in pairs, they could either be homozygous or heterozygous.

Homozygous pairs consist of either 2 dominant alleles or 2 recessive alleles. The genotype would look something like this:

2 dominant :RR                 or     2 recessive: rr

Heterozygous pairs consist of non-identical alleles, or it has one dominant and one recessive allele. So the genotype would look like this:

Rr

Finally, hybrid is the cross-breeding of two different species that are genetically different. There are many examples of hybrid species like the liger and the mule. The resulting off springs express traits that are different than both parents.

Answer:

It began after the stock market crash of October 1929, which sent Wall Street into a panic and wiped out millions of investors. Over the next several years, consumer spending and investment dropped, causing steep declines in industrial output and employment as failing companies laid off workers

Suppose the volume of milk in a glass is 230 cubic cm. If 1 gallon of milk equals 3.79 liters, there are how many glasses of mil
balu736 [363]
Volume of milk that a glass can hold = 230 cubic cm
It is already given that
1 gallon of milk = 3.79 liters
W already know
1 liter = 1000 cubic cm
Then
3.79 liters = 1000 * 3.79 cubic cm
                = 3790 cubic cm
Now
Number of glasses needed to contain 230 cm^3 of milk = 1
So
<span>Number of glasses needed to contain 3790 cm^3 of milk = 3790/230
</span>                                                                                           = 16.48
From the above deduction, we can conclude that 17 glasses of milk are required to hold 1 gallon of milk.
