The pericytes used in these experiments were probably in which phase of the cell cycle

Answers

Answer 1

Answer:

Answer: Interphase

The pericytes are in the interphase of the cell cycle. This is the phase of the cell cyclebetween each cell division and is the phase in which the cell obtains nutrients,grows, reads its DNA, and conducts other normal cell functions including thearrest of the growth of the pericytes that were treated so that they would notdivide but continue to function normally.

An experiment is designed to study the mechanism of sucrose uptake by plant cells. Cells are immersed in a sucrose solution, and the pH of the solution is monitored. Samples of the cells are taken at intervals and their sucrose concentration measured. The pH is observed to decrease until it reaches a steady, slightly acidic level, and then sucrose uptake begins. (a) Evaluate these results and propose a hypothesis to explain them. (b) Predict what would happen if an inhibitor of ATP regeneration by the cell were added to the beaker once the pH was at a steady level? Explain your thinking.

If a DNA molecule was a spiral staircase, what would the steps of the staircase be?

Answers

Answer:

Nitrogenous bases

Explanation:

DNA is a nucleic acid molecule that acts as the genetic material of the organisms. The structure of DNA is made of two strands of nucleotides that are linked together and form a helical structure. The helical structure is known as the double-helical model with a ladder-like appearance.

The backbone of the ladder is composed of the sugar and phosphate groups at alternate positions whereas the staircase of the ladder are made of the different type of nitrogenous bases (A, G, T, C) joined by the hydrogen bond.

Thus, Nitrogenous bases is the correct answer.

What is Index Fossil and Unconformity?

Index fossils are the fossils used to define and identify the different geological periods. The fossils must have a short vertical range with a wide range of geographic distribution and the rapid evolutionary trends.

A fossil indicates the relative age of a rock in which it is found. Index fossils come from species that were widespread but existed for a short period of time.

An unconformity is a buried erosional surface which separates two rock masses or strata of different ages, indicating that the sediment deposition was not continuous. A geologic unconformity is when an older rock formation has been deformed or partially eroded before a younger rock layer, usually a sedimentary rock is laid down which results in mismatched rock layers.

Thus, index fossils can be used as an evidence of unconformity.

True

Explanation:

Structure moves up against epiglottis when food is swallowed to prevent passage of food into it.a. The larynx
b. The nose
c. The pharynx

Answers

Answer:

The correct answer is A. The larynx moves up against epiglottis when food is swallowed to prevent passage of food into it.

Explanation:

The epiglottis is a moist, cartilaginous structure that is part of the cartilaginous skeleton of the larynx. It also marks the boundary between the oropharynx and the laryngopharynx. The epiglottis obstructs the passage of the bolus at the time of swallowing preventing it from going to the respiratory system.

Larynx closure occurs when the vestibular and vocal folds approach the midline during swallowing. Occasionally, when you eat very fast, solid foods or liquids can enter the larynx.
