The ribosomes makes proteins using coded instructions that come from the nucleus
Fatty substances such as cholestrol and saturated fats may be deposited on the inner surface of the coronary arteries. This narrows the lumen of these arteries and increases blood pressure. Such an affected artery develops a rough inner surface. This increases the risk of a blood clot being trapped in the artery. A blood clot that forms in an artery is called a thrombosis. Blood supply to the heart muscles can be greatly reduced due to the blockage of the coronary arteries. This can cause a heart attack. Hope this helps!
Answer:
B) an error occurred, the mass of the reactants should equal the mass of the products.
Explanation:
The answer choices are:
A) no error occurred, some of the products are always lost as heat.
B) an error occurred, the mass of the reactants should equal the mass of the products.
C) an error occurred, the products should weigh more than the reactants.
D) no error occurred, water is not weighed when determining the weight of the products.
Solution
The basis to answer this question is the law of conservation of mass.
Any chemical reaction satisfies the law of conservation of mass: mass cannot be either created nor destroyed, so, always, the mass of the reactants equal the mass of the products.
Thus, since he measured the mass of his reactant materials to be 35g and he reported that his products weighed 32g, his data are in clear contradiction of the law of conservation of mass. So, there is an error in his results: the mass of the reactants should equal the mass of the products.

I. Fruits aid in the dispersal of seeds by wind or by animals that carry or eat the fruits.
F. Seeds protect and nourish plant embryos, and fruits protect the seeds.
C. In many angiosperms, the male gametophyte contained in a pollen grain can be transported many miles away by wind or animal pollinators.
B. Seeds enable plant embryos to be dispersed long distances from the parent plant via wind or animals.
A. Flowers attract animal pollinators carrying pollen from other plants of the same species.
D. Floral parts of the saprophyte protect the reduced female gametophyte from drying out and from UV radiation.
