8 0

Answer:

Intramembranous ossification begins with differentiation of mesenchymal  cells.

Explanation:

Fibrous membranes are involved in the development of the bones. The process through which this occurs is termed as the intramembranous ossification.

The cells of the mesenchyma begin to split. These cells differentiate into specialized cells each performing different functions. The following bones are formed by the process of intramembranous ossification:

  • mandible
  • clavicle
  • some bones of the skull

Nadya [2.5K]

Answer:

The correct answer would be - "bacterial populations evolve in response to the selection pressure imposed by antibiotics".

Explanation:

The given information provided in the question about the bacterial infection supports the hypothesis that the bacterial population shows the evolution in response to the selection pressure caused by the antibiotics due to the fact that bacteria increased resistance gradually with time. This resistance towards antibiotics increased the percentage of bacterially infected children in the late 1980s and early 1990s.

In this case, the population of bacteria having resistance genes is selected to evolved selected to increase their offsprings.

NAD+ is a limiting factor in glycolysis. In the absence of ____________________ the conversion of (1) ____________________ to NA
scoray [572]

The correct options to fill in the gaps are:

  • ADP; NADH, and electron transport chain
  • alcohol fermentation; lactic acid fermentation; acetaldehyde; NADH; and NAD+

<h3>What is the role of NAD+ in glycolysis?</h3>

NAD+ serves as an electron acceptor in glycolysis. It accepts two electrons to become reduced to NADH + H+.

NAD+ is a limiting factor in glycolysis. In the absence of ADP, the conversion of NADH to NAD+ via the electron transport chain is prevented from happening.

In eukaryotes, the hydrogen atoms of the molecules mentioned in are transferred to certain organic molecules in one of two methods: alcohol fermentation as can occur in yeast and lactic acid fermentation as can occur in human cells. In the process mentioned in, the hydrogen atoms are passed to acetaldehyde, which is then converted to a molecule of ethanol. During this a molecule of NADH is oxidized to a molecule of NAD+, which allows glycolysis to continue on.

In conclusion, NAD+ concentration is limiting to glycolysis.
