Explanation:
Regan is trying to determine if an unknown element is a metal. She does not want to damage or change the physical appearance of the element in any way. Design an experiment that could determine if the mystery element is a metal without changing its appearance.
Explanation:
Well, one could use a magnet to see if it's ferrous. One could melt it to check which type it is, use a metal detector, or just use their senses: If it dings or clinks like metal, and feels like it’s texture. If it polishes with metal polish, is reflective, can be shaped or shape when heated… It usually is a metal. If it rusts, or oxidizes, it is or contains metal. If it “smells" like metal, most likely, it is metal. Finally, if it walks like metal, and quacks like metal, most likely we have a metal

Classification of organisms is defined as dividing living beings into different kingdoms based on their genetics, traits, and other features.
Why did Classification Schemes of taxonomists change?Taxonomists arrange and divide the organisms based on the DNA, traits, and features of the living organisms. The advancements in technology led the taxonomists to have more information on genetic lineage and arrange them accordingly. Introduction and discoveries of new species, their genetic make-up, and traits also contribute to the change of classification system. Molecular biology, cellular level studies, and genetics of species have contributed to the classification of organisms.
Thus, the given statements about the classification of organisms are correct.

Without genetic variation, natural selection would not be possible. Explain why.
Answer:
Without genetic variation, natural selection is only able to grow the number of allelomorphs that previously exited in the population. Natural selection occurs through an interaction between the environment and the variability of the individual organisms making up a population. If every giraffe had the same neck length, there would be nothing to change and they would never have a long neck by now.

Explanation:
Explain the mechanism of ventilation in human lungs (you should talk about the diaphragm, abdominal muscles and rib cage and intercostal muscles)
Answer: When the diaphragm contracts, it moves inferiorly toward the abdominal cavity, creating a larger thoracic cavity and more space for the lungs. Contraction of the external intercostal muscles moves the ribs upward and outward, causing the rib cage to expand, which increases the volume of the thoracic cavity.
The movement of diaphragm and ribs govern the mechanism of ventilation in human lungs.
The ventilation in human lungs or pulmonary ventilation is defined as the process of intake of air during inhalation, and expiration as the release out of air. It is also termed as breathing.
What is the mechanism of pulmonary ventilation?The lungs are present in the thoracic cavity, with the diaphragm below the lungs separating the thoracic cavity from the abdominal cavity. The rib cage is present outside lungs and prevent them.
Inhalation process in pulmonary ventilationThe inhalation is the process of taking in air. The increase in the volume of lungs results in the increased movement of diaphragm to the abdominal cavity.
The intercostal muscles move upwards and the rib cage move outwards. Thus, the air is inhaled in the system.
Exhalation process in pulmonary ventilationThe exhalation of air is performed antagonist to the inhalation. The relaxation of diaphragm and the movement of rib cage results in the decreased volume of the lungs, and the air is expelled.
Thus, the movement of diaphragm and ribs govern the mechanism of ventilation in human lungs.

Are any change in the sequence of bases in DNA or RNA that can cause by mutagen or can happen spontaneously in the cell
Answer:
MUTATION
Explanation:
Mutation is a change or alteration in the genetic sequence of a DNA or RNA (nucleic acid) that are induced by a chemical substance called MUTAGEN or by a spontaneous occurrence. Mutation are of different types depending on how it occurs in the cell. A mutation can be deletion (removal), substitution (replacement), insertion (addition) etc.
Based on this question that states that "any change in the sequence of bases in DNA or RNA that can be caused by mutagen or can happen spontaneously in the cell", the process of MUTATION is being described.

If a gene has two alleles, there are two possible genotypes.
a. True
b. False
Answer:
b. False
Explanation:
Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.
Heredity refers to the transfer of traits (specific characteristics) from the parent of a living organism to her offspring through sexual reproduction or asexual production. Some examples of hereditary traits are dimples, tongue rolling, baldness, handedness, freckles, curly hair, color blindness, height, etc.
According to Mendel's Law of Dominance, if a gene has two alleles, there are three (3) possible genotypes.
The three (3) possible genotypes are;
I. A combination of alleles such as AA.
II. A dominant combination (phenotype) such as Aa.
III. A recessive combination such as aa.
Where;
A represents the dominant allelea represents the recessive allele.Also, a single version of a gene expressed by a living organism is referred to as an allele.
how can we control bacterial disease?
Answer:
Bacterial diseases are treated with antibiotics. Antibiotics work by killing the harmful bacteria or by stopping them from reproducing and spreading. Different types of antibiotics are effective for treating specific types of bacteria.

Bacteria can convert nitrogen in the air into a form plants can use.
The earth atmosphere contain a huge amount of oxygen which is needed by plants. These Nitrogen can be converted into a form in which can be used by plants through a process known as nitrogen fixation.
Fixation is a process that converts nitrogen in the atmosphere into forms in which plants can use. Nitrogen can be fixed using fertilizer.

what's mitosis and meiosis?
Answer:
MITOSIS AND MEIOSIS*Most of the time when people refer to “cell division,” they mean mitosis, the process of making new body cells. Meiosis is the type of cell division that creates egg and sperm cells. ... During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells.
What meiosis means?Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction. ... Meiosis begins with a parent cell that is diploid, meaning it has two copies of each chromosome.
What is mitosis explain?Mitosis is a process where a single cell divides into two identical daughter cells (cell division). During mitosis one cell? divides once to form two identical cells. The major purpose of mitosis is for growth and to replace worn out cells.
What is meiosis important?Meiosis is important because it ensures that all organisms produced via sexual reproduction contain the correct number of chromosomes. Meiosis also produces genetic variation by way of the process of recombination.
What is Mitosis important?Mitosis is a way of making more cells that are genetically the same as the parent cell. It plays an important part in the development of embryos, and it is important for the growth and development of our bodies as well. Mitosis produces new cells, and replaces cells that are old, lost or damaged.
What is Mitosis means?Mitosis is a process where a single cell divides into two identical daughter cells (cell division). ... The major purpose of mitosis is for growth and to replace worn out cells.
What Meiosis explain?Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction. ... Meiosis begins following one round of DNA replication in cells in the male or female sex organs.
