Answer:
DNA replication is the process by which DNA makes a copy of itself during cell division.
Hope it helps!!
Answer:
DNA replication is the process by which DNA makes a copy of itself during cell division. The first step in DNA replication is to 'unzip' the double helix structure of the DNA? molecule. ... The separation of the two single strands of DNA creates a 'Y' shape called a replication 'fork'.

Answer:
process of fossilization , which mineral deposits form internal casts of organisms.
Explanation:
Answer:
this is a process of fossilization in which mineral deposits from internal casts of organisms. when carried by water, these minerals fill the spaces within organic tissues. examples are most dinosaur bones, petrified wood and many trilobite fossils
Explanation:
when an organism is berried, the minerals which are carried by water, for example, silica, calcite or pyrite will replace the organic material in the fossil.

Answer:
the mRNA goes through extensive modifications such as addition of a poly tail and a 5' cap in eukaryotes but not in prokaryotes.
Differences:
- the promoters in prokaryotes have a -35 and -10 box while in eukaryotes they are variable but have a TATA box from
- the transcription initiation site there is a single RNA polymerase in prokaryotes while eukaryotes have multiple RNA polymerases
- the sigma factor associates with the promoter region in prokaryotes but in eukaryotes there are many basal transcription factors
Explanation:
Ribosomal and transfer RNAs are processed both in prokaryotic and eukaryotic organisms. However, mRNA is only processed in eukaryotes. In eukaryotic cells, mRNA processing involves:
1. Capping at the 5' end. This process has several functions including regulation of nuclear export, prevention of eukaryotic mRNA degradation and promotion of translation.
2. Splicing in order to remove introns and conserve coding exons. Splicing helps to increase the diversity of the eukaryotic mRNAs (and therefore eukaryotic proteins)
3. Polyadenylation by the addition of a poly(A) tail at the 3' end. The poly(A) tail makes the eukaryotic mRNA molecule more stable and also prevents its degradation by exonucleases.

Which of the following is an inherited trait?
A. Freckles
B. Being a good reader
C. A birthmark
D. A scar
Answer:
A. freckles
Explanation:
inherited traits are things you are born with that resemble your parents like freckles, color hair and skin even eyes and other such things
The inheritance of traits depends on the genes, not on the somatic cells. In the given choices, freckles are inherited from parents to offspring.
What are freckles?Freckles are caused by either sun or by genes. The presence of this can be due to the genes carrying it.
Genetics and sun exposure is the main cause of freckles. There are a number of genes involved, and they can interact with one another in lots of different ways.
Somatic variations are not likely to get inherited.
Thus, the correct option is A.

There are several buffer systems involved in maintaining blood pH, but one is more important than the others for maintaining acid-base homeostasis in blood. To understand why an acid-base imbalance in the blood results from respiratory depression, you must first identify the major buffer system responsible for controlling blood pH. Which equilibrium reaction is the most important for maintaining acid-base homeostasis in the blood?
Answer:
The Carbonic-Acid-Bicarbonate Buffer. In animals with lungs, the carbon / bicarbonate buffer system is especially effective. In these animals, the H2CO3 in the blood plasma is in equilibrium with the gaseous CO2 present in the airspace of the lungs, which represents a practically unlimited reserve of CO2 that can participate in the equilibrium.
Explanation:
In the Carbonic-Acid-Bicarbonate buffer system, 3 reversible equilibria take place between the CO2 gas in the lungs and the bicarbonate dissolved in the blood. The bicarbonate ion (HCO3-) can combine with a proton (H +) to form carbonic acid (H2CO3), thus absorbing protons from solution and raising blood pH. Carbonic acid, which can be formed from CO2 and water, can dissociate into H + and HCO3- to provide H + and lower blood pH. Carbonic acid, which can be formed from bicarbonate, is converted to CO2 and water by a very fast enzymatic reaction. CO2, being volatile, can be rapidly eliminated from the body in variable amounts through respiration.In the clinic, the system that is measured for the assessment of the acid-base status is the carbonic / bicarbonate system.

A cleft chin in humans is coded by the dominant allele C. A chin without a cleft is coded by the recessive allele c. A man with a cc allele combination for the trait produces a zygote with a woman with a Cc allele combination for the trait. Which allele combinations could occur in the zygote?
Answer:
The allele combinations are: Cc, cc, Cc, cc
Phenotypically there is a 50% chance that the child will be born with or without the cleft
The allele combinations that could occur in the zygote is Cc or cc.
What is an allele combination?An identification of the specific alleles found at each of the relevant mouse loci on the two homologous chromosomes (i.e., all allele pairs of a genotype). One or more allele pairs can make up an allele combination.
Genetic linkage is the capacity of a chromosome to transmit alleles that are near to one another as a whole unit through meiosis. Inheritance of traits is also understood by this principle. It is useful in locating the genes that are in charge of characteristics and diseases.
The person is homozygous for the allele if the two alleles are the same. The person is heterozygous if the alleles are different.
Therefore, the zygote may include the allele combinations Cc or cc.

The skin cells of an organism are analyzed and cells identified in G1 and have an average of 12 picograms of DNA. In the same organism a cell from gonadal tissues is identified and that single cell contains 6 picograms of DNA. Given this information, which of the following is true about the single gonadal tissue cell with 6pg of DNA?
1. The cell is at the beginning of Prophase I.
2. The cell has already completed meiosis.
3. The cell is not dividing (is in interphase).
4. The cell contains unduplicated chromosomes.
Answer:
El Rasho Macuin
Explanation:
The statement which is true about the single gonadal tissue cell with 6 picograms of DNA is that the cell has already completed meiosis. So, the correct option is B.
What do you mean by DNA?It is a complex molecule that contains all the information necessary to build and maintain an organism. It stands for Deoxyribonucleic acid. It is considered the genetic material in most organisms.
The skin cells in the G1 phase have an average of 12 picograms of DNA. As the amount of DNA in the G1 phase is 2C, hence 2C = 12 pg of DNA.
Now in the same organism, a cell from gonadal tissue is identified and that single cell contains 6 pg of DNA, which means, the amount of DNA is 6 pg that is C. Therefore, after the completion of meiosis, the cell contains half the amount of DNA as compared to the parent cell in G1.
So, Amount of DNA = C = 6 pg.
Therefore, the statement which is true about the single gonadal tissue cell with 6 picograms of DNA is that the cell has already completed meiosis.

According to the chart below, which planet contains the most hydrogen gas?
Saturn
Jupiter
Venus
Earth
Answer:
Saturn
Explanation:
As you can see from the chart, the hydrogen gas is labeled by the turqoise part of the bar chart. To find which one has the most hydrogen gas, select the planet where the bar with hydrogen gas is the highest. If you compare, you will notice that neptune and jupiter have the least because the hydrogen gas is lowest on the bar chart, Saturn and uranus have a higher concentration of this gas but saturn has more than uranus respectively.
Mercury is often used in thermometers. The mercury sits in a bulb on the bottom of the thermometer and rises up a thin capillary tube as the temperature rises. Suppose a mercury thermometer contains 3.380g of mercury and has a capillary that is 0.200mm in diameter. How far does the mercury rise in the capillary when the temperature changes from 0.0 0C to 25.0 0C
Answer:
3.5 cm
Explanation:
Mass of mercury = 3.380
Diameter = 0.200
At t = 0 and 25 degrees we have 13.596 and 13.543 as density
At 0 degree = v = 3.380/13.596 = 0.2485
At 25 degrees = 3.380/13.534 = 0.2497
We use volume of cylinder to get height
At 0⁰ height = 7.91
At 25⁰ = 7.944
The difference in height = 0.035
Multiply by 100 = 0.35 x100
= 3.5cm
