Answer:
Mutations can occur from the following ways:
1. Errors that occur in DNA replication during cell division
2. Exposure to high-energy electromagnetic radiation
3. Exposure to chemicals mutagens
Effects of mutation include:
1. Genetic disorders
2. Cancers
Explanation:
A mutation is a change or alteration that occurs in the DNA sequence of a cell of an organism. These mutations can be passed on to offsprings of that organism. Mutations can occur from the following ways:
1. Errors that occur in DNA replication during cell division: during the process of cell division, the DNA in cell are copied many times. Some errors result when copying DNA, most of which are corrected during proofreading. However, some changes in the DNA sequence may not be corrected, thus resulting in a mutation.
2. Exposure to high-energy electromagnetic radiation: some types of electromagnetic radiation are ionizing, such as UV rays and X-rays. Prolonged exposure to these ionizing radiation may result in permanent damage to parts of the DNA, thereby resulting in a mutation.
3. Exposure to chemicals mutagens: mutagens are substances which are able to cause mutations. Some common chemical mutagens are alkylating agents such as ethylmethane sulfonate and N-methyl-N-nitrosourea.
Effects of mutation include:
1. Genetic disorders: in genetic disorders, certain normal functioning of the body processes are impaired. For example, hemophilia whereby blood lacks the ability to clot normally resulting in excessive bleeding.
2. Cancers: cancers occur when the cell of the body differentiate and grow abnormally. Various types of cancers include breast cancer, prostrate cancer, blood cancer etc.
Interogenes are genes that cause a cell to continuously divide. These genes are usually targeted by doctors who are trying to stop tumors from developing. If a doctor wanted to prevent mutations that cause interogenes from being copied, which part of the cell cycle would the doctor be trying to prevent?

Answer:
By crossing plants with purple flowers, dominant, with plants with white flowers the offspring will be 100% purple because all the offspring will receive at least one dominant allele.
Explanation:
The crossing of two plants of pure line, one dominant and one recessive, for a trait —the color of the flowers— will produce a hybrid offspring which will express the dominant trait in its phenotype.
Parental generation:
Plant with purple flowers PP Plant with white flowers ppCross: PP X pp
Punnett Square :
Alleles P P
p Pp Pp
p Pp Pp
Offspring: 100% Plants whose phenotype is purple flowers and Pp genotype.
According to this, the descendants will be 100% plants with purple flowers, hybrids, since all the offspring received at least one dominant allele.

1) A vehicle is traveling at 150 km/h after 3 hours it is traveling 240 km/h.
Was the vehicle accelerating or decelerating and at what rate?
(And this is for science not biology)
Answer:
Accelerating (30km/hr²).
Explanation:
In physics, acceleration can be defined as the rate of change of the velocity of an object with respect to time.
This simply means that, acceleration is given by the subtraction of initial velocity from the final velocity all over time.
Hence, if we subtract the initial velocity from the final velocity and divide that by the time, we can calculate an object’s acceleration.
Mathematically, acceleration is given by the equation;
[tex]Acceleration (a) = \frac{final \; velocity - initial \; velocity}{time}[/tex]
[tex]a = \frac{v - u}{t}[/tex]
Where,
a is acceleration measured in [tex]ms^{-2}[/tex]v and u is final and initial velocity respectively, measured in [tex]ms^{-1}[/tex]t is time measured in seconds.Given the following data;
Initial velocity, u = 150km/h
Final velocity, v = 240km/h
Time, t = 3 hours
Substituting into the equation, we have;
[tex]a = \frac{240 - 150}{3}[/tex]
[tex]a = \frac{90}{3}[/tex]
Acceleration, a = 30km/hr²
Therefore, the vehicle is accelerating at the rate of 30km/hr² because its final velocity is greater than its initial velocity.
For deceleration, the final velocity of an object such as a vehicle would be lesser than the initial velocity.

The geologic species scale has units based on changes in rocks and fossils.
True
False
The geological time scale/species scale is divided into different units of time depending on changes in the rocks and fossils. So the statement is true.
What is the geological time scale?
The lengthy period of time that the Earth's geologic history has taken up is known as geologic time. Starting at the beginning of the Archean Eon (4.0 to 2.5 billion years ago), formal geologic time runs to the present.
The Hadean Eon, an informal time period that runs from around 4.6 billion years ago (corresponding to Earth's first creation) to 4.0 billion years ago, is also frequently included in modern geologic time scales. The period of Earth's history that is reflected by and preserved in the planet's rock layers is known as geologic time.
Events throughout Earth's history are "calendared" according to the geologic time scale. It divides all of the time into named units of abstract time known as eons, eras, periods, epochs, and ages, in declining order of duration. Those geologic time units are counted according to stratigraphy, the correlation, and the categorization of rock layers.
Therefore, the geological time scale is used for dividing different units of time according to changes in rocks and fossils. Hence the statement is true.

Answer:
Chargaff's rules state that DNA from any species of any organism should have a 1:1 stoichiometric ratio of pyrimidine and purine bases and, more specifically, that the amount of guanine should be equal to cytosine and the amount of adenine should be equal to thymine. This pattern is found in both strands of the DNA.

The correct and most appropriate words to fill in the blanks are: peptide, water and protein.
An amino acid can be defined as a simple organic chemical compound that is made up of an acidic carboxyl group (COOH), a basic amino group ([tex]NH_2[/tex]), and a variable (unique) side chain group.
Generally, an amino acid is typically named after two (2) of its functional groups and these are:
An acidic carboxyl group (COOH): it acts like an acid.A basic amino group ([tex]NH_2[/tex]): it acts like a base.
Basically, a peptide bond is formed between two amino acids when they unite. Also, this chemical reaction lead to the release of a molecule of water.
Finally, the union of many amino acids forms a macromolecule called a protein.
In conclusion, protein is a macromolecule which is formed as a result of the union of many amino acids.
