What is the purpose of the pericardial sac that surrounds the heart in mammals
Nitella [24]

Answer:

Pericardial sac has protective tole

Explanation:

Pericardial sac or pericardium is a fibrous tissue that surrounds the heart. It has two coats:

  1. the outter coat-parietal pericardium
  2. the inner coat-visceral pericardium or epicardium which is double-layered and contains pericardial fluid between those two layers (pericardial fluid is necessary as a lubricant for the heart movement).

Besides lubrication, percardium also protects heart from infections, fixes it and limits its movements.

Identify the substances that can readily pass through the inner mitochondrial membrane.
KIM [24]

Answer:

A,C E

Explanation:

The inner membrane of the mitochondria separate the matrix of the mitochondria from the cytosol(inner membrane space.). It is invaginated  folded inwards  to form the critae. This is an adaptive feature to increase the surface area for biochemical reaction in the mitochondria.

The invagination gives two compartments the inner mitochondria also creates the outer intermembrane space and the inner matrix

These are the substances that can pass freely the inner membrane of the mitochondria.Pyruvate and H+ can not pass through.Specifically,it is not preamble to H+ because, hydrogen ions are needed to generate the electrochemical gradients needed for the chemical energy  for phosphorylation of ADP by  P to form ATPs by the enzyme ATPase synthase.If the inner membrane is permeable to H+ the electochemical gradient will not be produced, and therefore ATPs productions stops.

O2 needs to pass through the inner membrane because it it the final electron acceptor. Therefore if not allowed to pass through oxidative phosphorylation  and ETC will nor occur.

CO2 must pass through because its accumulation will increase the acidity of the inner  mitochondria

Why do you think DNA is duplicated before
Anna71 [15]

The two cells that result from a single cell need to have the same amount of genetic material as the initial cell, therefore the DNA needs to be duplicated before the cell divides.

The sister chromatids are attached together so that during anaphase the daugther cells will receive the same chromosomes
