Answer:

A: Discovery of DNA as the genetic material

Explanation:

DNA is the genetic material and stretch of DNA that codes for a specific protein is called as gene. Discovery of DNA as genetic material provided the physical proof of Mendel's factors that were responsible for transmission of genetic traits in his experiment.

Discovery of DNA as genetic material also established that genetic variations among individuals of the species as described by Darwin are due to minor differences in their DNA molecules.

Hence, discovery of DNA as genetic material led to acceptance of both Mendel's law and Darwin's theory.

Answer:

No, not really. Over time, organisms have grown much more complex. Photosynthesis happened around 3.4 billion years ago and respiration around 2 billion years ago. These all serve as a testimony to the fact that organisms are in fact growing more complex. We have seen photoautotrophs arise, from the simpler chemoautotrophs, and they now in fact dominate the array of producers! Organisms don't only do fermentation now; they can also do anaerobic respiration and aerobic respiration too! Thus, current life forms are a lot more different today than 3.8 billion years ago.

Answer:

in dogs there is a hereditary type of deafness caused by a recessive gene. Two dogs who carry the gene for deafness but have normal hearing are mated. what are the possible genotypes and phenotypes of their offspring and the percent of chance for each?

Dd x Dd = DD, Dd, Dd, and dd

3:1 genotype

phenotype shows that there is 3 dominant gene for normal hearing while 1 for deafness (two homozygous where 1 is dominant and the other is recessive) and (two heterozygous with normal hearing dominant over deafness recessive)

Zolol [24]

Answer:

In quiet breathing inspiration involves muscular contractions and expiration is passive.

Explanation:

Respiration process involves two different stages, inspiration - inhalation- and expiration - exhalation-.

During inspiration, the diaphragm contracts and goes down, while intercostal muscles also contract and go up. These actions enhance the size of the thoracic box and reduce internal pressure. As a result, air flows in and fills the lungs.

During expiration, the diaphragm relaxes and the volume of the thoracic box diminishes, which causes the pressure inside to increase. In consequence, the lungs contract and the air is expulsed outside.
