Answer:
The increased production of pericardial fluid leading to restriction of the movement of the heart is called <u>cardiac tamponade</u>.
Explanation:
Cardiac tamponade refers to the pressure in the heart caused by the accumulation of blood or fluid between the two layers of the pericardium, compressing the heart. This disorder affects the pumping capacity of the heart, which does not allow the heart to fill with blood. As a result, less blood is pumped into the body, causing a severe picture under cardiac output or shock (with a dangerous decrease in blood pressure) and even death.
Answer:
Weight in mice is a polygenic trait
Explanation:
Her observation might be as a result of the weight trait being a polygenic trait. A polygenic trait is a trait are train that are controlled by two or more genes. Additive interactions of these genes can influence expression of the trait. Thus weight is expression of a trait influenced by two or more genes. This to knock out the trait, she has to all genes involved in the expression and not just one gene.
Answer:
we use the equation
kinetic energy (Ek)=1/2*mv²
when we rearrange the equation we get speed (v) as
root of 2Ek/m=speed
so root of 2(500)/2=10 root 5m/s or 22.36m/s
Urinal system aka renal system
The plant cells have the cell wall made up of cellulose. In case, a cell represents the presence of cell wall then it is most likely to belong to plant cells.
Other than plant cell fungi as well as some protozoa also possess the cell wall, but the cell wall made up of cellulose is exclusively present in the plant cells.
So, the cell sample collected in this case is most likely came from a plant.
