Answer:

Tissue.

Explanation:

A tissue is a <u>group of cells</u> which performs a specialized function in the body of a multi-cellular organism.

In a unicellular organism tissue level of organisation does not exist and only a single cell performs all the vital functions like respiration, digestion, reproduction etc. But since a single cell performs all the functions, it is unable to perform all these functions with high efficiency because <u>a single cell can not perform all the functions efficiently.</u>

In contrast to this, a multi-cellular organism has a tissue level of organisation. In such organisms many cells form a group to make a tissue which performs only one specialized function which leads to great efficiency. For example, nervous tissue performs the function of responding to various stimuli only and does not indulge in any other work in the body, cardiac tissue is meant for circulation of blood etc. This is known as division of labor. Each tissue performs its own specialized function for one individual and hence enhance the efficiency of work in the organism.

Viktor [21]

Answer:

Genetic drift

Explanation:

Genetic drift is an evolutionary mechanism that in a population it changes allelic frequencies over generations just by chance. For this reason, small populations are more susceptible to be affected by genetic drift than bigger populations.  

In this example, Indiana Jones visited a small village of 50 people and over generations allele A probably was lost just by chance, or by genetic drift.

Which of the following options lists the stages in cellular respiration in the correct order? glycolysis, the citric acid cycle,
marishachu [46]

Answer:

The correct answer is  glycolysis, the citric acid cycle, and oxidative phosphorylation

Explanation:

Aerobic respiration contains three major processes that are glycolysis, the citric acid cycle, and oxidative phosphorylation.  

In glycolysis, partial oxidation of one mole of glucose gives two moles of pyruvate and 2 NADH and 2 ATP. Then this pyruvate is converted into acetyl-CoA in the mitochondrial matrix(in eukaryotes) and acts as a fuel for the Krebs cycle.

In the Krebs cycle, acetyl CoA gives rise to 4 CO₂, 2 ATP, 6 NADH, and 2 FADH₂. So from glycolysis and Krebs cycle, only 4 ATP is produced and most of the energy remains in the form of NADH and FADH₂.

So in oxidative phosphorylation electrons are released from these molecules into machinery of oxidative phosphorylation to synthesize ATP.

g 20. Name two bones connected by an interosseous membrane found in the crus and/or sural region. Which one is the medial bone
slamgirl [31]

Answer:

Tibia and fibula. Tibia (medial bone)

Explanation:

The tibia is the medial bone of the lower leg (it is the second-largest bone next to the femur), whereas the fibula is the lateral bone of the lower leg. The tibia functions to transmit the majority of the force in the lower leg. The tibia articulates at the proximal end with the femur and fibula; where this bone (tibia) articulates at the distal end with the fibula and the talus bone of the ankle. The tibia and fibula are connected via an interosseous membrane, which is a thin sheet of connective tissue that spans the space between two bones.
