Genetic mutations are the changes in the genetic code and composition of organisms.

Genetic mutation can occur due to many factors like insertion, deletion, inversion of chromosomes.

The correct answer is:

Option A. Some inherited genetic mutations can be good for the offspring.

• Mutations can be advantageous, inert or dangerous based upon the location of the genes.

• Some mutations like in the case of sicklecell anemia in some communities conferred them resistance towards malaria disease.

• The mutation can be beneficial as it can raise the chance of survival of the offspring.

Therefore, some inherited geneticmutations can be good for the offspring.

Answer:

Your answer is A.Some inherited genetic mutations can be good for the offspring.

Explanation:

The principle of segregation given by Gregor Mendel based on his experiments with the pea plants states that alleles of a gene for any trait are segregated during the formation of the gametes. Therefore, a gamete contains only one allele of a gene. When the male and female gamete combines during fertilization, the two alleles (one from each gamete) combine to form the gene.

Hence, the correct answer is 'Option B - A gamete carries one allele for a gene'.

Answer: The correct answer is- B. A gamete carries one allele for a gene.

Gamete ( also called sex cell or reproductive cell) is a haploid cell ( having half number of chromosome as compared to the parent cell) that is produced through a cell division, termed as meiosis in sexually reproducing organisms.

According to Mendel's second law of inheritance that is law of segregation,

For every trait/ characteristic of an individual, there are two variant forms of a gene (called alleles) that are separated from one another so that every gamete possesses one allele. This law is also known as law of purity of gametes.

Thus, option B) is the right answer.

An advantage of electron microscopes compared to light microscopes is that electron microscopes have higher resolution that allows you to view smaller specimens

The best microscope to view living single-celled organisms in a sample of pond water is called the Compound light microscope

For better understanding, we have to understand what electron microscope and compound light microscope is.

• The Compound Light Microscope is one of the most commonly used microscope. It is said to have a Magnifying intensity that ranges from from 40x up to 1,000x. It is often used to observe specimens that can either be dead or alive. It allows the use of dye on the slide to view tissue samples, blood, microorganisms in pond water, microscopic cells and others. It often allow light to pass through the said specimen and includes the use of two lenses to form an image.

• Electron Microscope is simply known as a type of microscope that involves the use of a beam of electrons instead of the use of light to enlarge objects. It can enlarge up to 500,000 times it's actual size. It has much higher resolving power that is higher clarity than light microscopes due to the fact that it uses electrons instead of light.

From the above, we can say that An advantage of electron microscopes compared to light microscopes is that electron microscopes have higher resolution that allows you to view smaller specimens and
