Mutations:
Mutations are the changes produced in the nucleotide sequence of the genome.
There are four main types of mutations
Substitution
Insertion
Deletion
Duplication.
_____________________________________
DELETION:
A small segment of chromosome mat be missing. This condition is known as deletion.
For example, Normal chromosome has A B C D E F G. If deletion mutation occurs then mutated chromosome has A D E F G and B C got deleted.
_____________________________________
DUPLICATION:
In this condition, a part of chromosome present in exec ess to the normal chromosome.
For example, Normal Chromosome has A B C D E F G. If duplication mutation occurs, then mutated chromosome had A B C B C D E F G and B C is duplicated.
_____________________________________
SUBSTITUTION MUTATION:
Substitution is a type of mutation where one base pair is replaced by a different base pair.
For example, in the sequence CAAGT, if C replaces G, it is a substitution mutation.
INSERTION MUTATION:
In genetics, an insertion is the addition of one or more nucleotide base pairs into a DNA sequence.
For example, in the sequence CAAGT, if extra base G gets inserted after C, the new sequence would be CGAAGT.
_____________________________________
Both substitution and insertion mutations change the position of nucleotide thus, the type of amino acid. Option A is correct because B and D are wrong as increase in number of bases and decrease in number of bases is because of deletion and duplication mutations here it asks for substitution and insertion mutations. C is wrong as In mutation there is always a change in bases or chromosome. So all the other choices seem incorrect as it is asking for substitution and insertion the base pair changes which results in the change in type of amino acid.

Answer:
D. Rolling a six-sided number cube and using the number on the top side.
Explanation:
I majored in Biology
The best method for randomly determining how many eggs an imaginary bird lays in a simulation would be to roll a six-sided number cube and use the number on the top side. Therefore, option (D) is correct.
What is a simulation?A simulation is a computer program or model that imitates a real-world system or process. It allows researchers, scientists, engineers, or other users to understand, predict, or test the behavior of a system or process under different conditions or scenarios. Simulations are used in various fields, including engineering, physics, chemistry, economics, medicine, and social sciences, among others.
They often involve mathematical or statistical models, algorithms, and computer graphics or visualizations to represent the system or process being simulated. By running a simulation, users can observe the results, draw conclusions, and make predictions about the behavior of the real-world system or process. Simulations can be helpful in decision-making, experimentation, training, and education, among other applications.

Which one of the following is the name for the way cells divide in asexual reproduction?
Twins
Mitosis
Meiosis

Answer:
Mitosis
Explanation:
When a eukaryotic cell divides asexually, the nucleus and its genetic contents must divide too, in a process called mitosis. Both haploid (n) and diploid (2n) cells can divide asexually, at which time their nuclei divide mitotically.

Describe how 4 different organ systems are used to help you ride a bicycle. Be detailed about the job of each organ system to complete this task. Answer in complete sentences for full credit.
Answer:
Your skeletal system supports your body as you move your legs to pedal. Your muscular system lets you tighten your hand around the handlebars to steer the bicycle. As you pedal faster, the speed of your breathing increases. This means that your respiratory system is breathing in more oxygen for your cells to use.

Question 11
Which statement best describes the relationship between inherited traits and genes?
A
An individual's inherited traits are determined by genes, which are located inside a person's chromosomes.
B
An individual's inherited traits are based on a person's environment, and the traits change over time.
С
Inherited traits are determined by a person's health and nutrition.
D
Inherited traits are determined only by a person's maternal parent
Answer: A. Genotype is inherited
Explanation: b,c are about phenotype
D, since the maternal parent is mentioned, one can assume a diploid, sexually reproducing species, in which case both parents’ genes contribute.
Through their genes, parents transmit features or qualities to their offspring, such as eye color and blood type. Thus, option A is correct.
What is relationship between the inherited traits and genes?We can pass on inherited features to the next generation since they are encoded in our DNA.
Examples include eye color, height, skin tone, and hair color. The differences that come from reproduction may be passed down through families, increasing the likelihood that entities will survive.
Dominant and recessive alleles are the two categories. A recessive allele is written with a lowercase letter, and a dominant allele is written with a capital letter.
The progeny will exhibit the dominant trait if a gene pair contains the dominant allele.
Therefore, An individual's inherited traits are determined by genes, which are located inside a person's chromosomes.

Explanation:
Which part of the female reproductive system sheds during the menstrual cycle?
Answer:
Endometrium / Uterine lining
Explanation:
The change in the production of the hormones Estrogen and Progesterone dictate a female's menstrual cycle. For about three weeks, the endometrium which lines the inside of the uterus thickens. If that female becomes pregnant, the endometrium stays as it's actually what a fetus uses to grow, like the yolk in an egg. If the female does not become pregnant, the uterine lining is shed. Most mammals simply absorb it back into the body, but in humans, the uterus contracts and sloughs it off, sending it through the vaginal canal and out of the body, a process which takes about a week.
