Answer;
The fibrous pericardium is not distensible, which causes the blood to put pressure on the heart, constricting it and reducing its ability to contract
Explanation;
-Cardiac tamponade is a clinical syndrome caused by the accumulation of fluid in the pericardial space, resulting in reduced ventricular filling and subsequent hemodynamic compromise.
-The most common causes of cardiac tamponade are; rupture of an aortic aneurysm (a bulge in the wall of the aorta), advanced lung cancer, acute pericarditis (inflammation of the pericardium), a heart attack, and heart surgery.
Answer:
Homologous pairs of chromosomes are lined up independently of other such pairs during <u>metaphase I.</u>
Explanation:
Meiosis is a special type of nuclear division that occurs only in organisms with sexual reproduction. The meyotic division gives rise to gametes.
The division begins just after the chromosome DNA has replicated in the S phase. Each chromosome is made up of two identical sister chromatids joined by their centromere. However, chromosomes are not kept separate in the nucleus, but instead bind to their homologous partners. This union called synapse, occurs during prophase I.
In metaphase I, the pairs of chromosomes are aligned in the spindle Ecuador, that is, during this stage, the homologous pairs are aligned in the metaphase plate (which is the equatorial plane of the achromatic spindle) for separation.
During anaphase I, the members are directed to the opposite poles of the cell. Telophase I, this phase begins with the arrival of chromosomes at the poles and with the formation of a nuclear envelope around each group of chromosomes. During Profase II, the nuclear membrane (if formed during Telophase I) dissolves, and spindle fibers appear.
The first meyotic metaphase and anaphase is usually completed in a short time to give rise to the phases of the second division (metaphase II and anaphase II) , which is a mitosis during which the centromeres divide and the chromatides move towards opposite poles to become gamete chromosomes. In telophase II, cytokinesis separates cells.
Biomass decays and produces gases such as nitrogen and very small amount of helium. in many places it is used to produce energy by comustion.it's mass becomes less and a layer of humus type organic substance is left on the soil....if i'm not incorrect :)
It is chloroplast because thats where everything happens and works
