Answer:

Genetic mutations are passed from parent to offspring by mutated gametes (sex cells) which are fuse to create offspring.

Explanation:

Genetic mutations or germline mutations can be defined as permanent change in the DNA sequence of germ cells (cells, which form ovum and sperm). These mutations can pass from one generation to other, when a mutated sperm or mutated oocyte (gametes) get fertilized with other oocyte or sperm.

When a single celled zygote containing genetic mutations divides then this mutation spreads to the whole cells of an organism.

DNA that is only passed on from mothers to their children is stored in mitochondria,Mutations in mitochondrial DNA (mtDNA) are important causes of various types of diseases.

THUS THE GENETIC MUTATIONS ARE PASSED FROM PARENTS TO OFFSPRING BY MUTATED GAMETES ,FUSING TO CREATE OFFSPRING.

The only mutations that matter to large-scale evolution are those that can be passed on to offspring. These occur in reproductive cells like eggs and sperm and are called germ line mutations. A single germ line mutation can have a range of effects: No change occurs in phenotype.

During cellular respiration, the first CO2 is generated during _____ and the remaining carbons are given off as CO2 during _____

Julli [10]

Answer:

Glycolysis and Krebs cycle.

Explanation:

During cellular respiration, the first carbondioxide gas is generated during glycolysis while the remaining carbons are given off as carbondioxide during Krebs cycle. During the process of glycolysis in cellular respiration, glucose is oxidized forming carbondioxide and water whereas during the Krebs cycle, the two carbon atoms of acetyl-CoA are released and each turns into a carbondioxide molecule.

Failure in a particular structure of the heart tends to cause a backup of blood in the lungs, known as pulmonary congestive hear

xeze [42]

Answer:

Left ventricle.

Explanation:

Human heart is divided into four chambers - two auricles and two ventricles. Heart acts as the pumping organ and carries both oxygenated and deoxygenated blood in the right and left ventricles.

The failure of functioning of any chamber of heart may cause a particular disease in the individuals. The pulmonary congestive heart failure occurs due to the failure of the left ventricles of the heart. The left ventricle carries blood from heart to the body tissues, its failure leads to the backup of blood in the lungs.

Thus, the answer is left ventricle.
