From the table, we can see that; 1 = beta; 2 = alpha, 3 = gamma. Option A
<h3>What is radiation?</h3>
Radiation is a form of energy that can not be seen. We know that beta radiation can be stopped by such things as a piece of cloth while alpha particles can be stopped by an aluminums foil. Also, gamma rays can only be stopped by thick concrete or lead.
Hence; we can conclude that; 1 = beta; 2 = alpha, 3 = gamma. Option A.

the answer is a basalt rock.
Answer:
The correct answer is- tertiary consumer.
Explanation:
The position of organisms which they occupy in a food chain or food web in a ecological pyramid is called trophic level. Base of the pyramid is occupied by the producers and the level is occupied by primary consumer and then secondary conumers and so on.
In the given list of organims present in the Amazon rainforest, jaguar and anaconda are largest predators which occupy the top level of pyramid, thus they are tertiary or top consumers of Amazon rainforest food web.
Answer:
Scientists define density as the mass of a substance per unit volume. The word “per”
signals that thinking about density requires thinking about a relationship. It is the relation
between the mass (or weight) of one unit of a material and the volume of that one unit.
Density cannot be directly perceived or measured. It must be inferred from the
relationship of the mass and volume. However, it can be determined by calculation
which is how many schools teach it. To calculate density, you first measure the weight
and volume of an object precisely, then you divide the mass by the volume (i.e. d=m/v,
density equals mass divided by volume). So for example, the density of water is 1 gram
per cubic centimeter because a volume of 1 cubic centimeter of water has a mass of 1
gram. A substance which has a mass of greater than one gram per cubic centimeter
has a density greater than 1.0 gram per cubic centimeter; a substance which has a
mass of less than one gram per cubic centimeter has a density of less than 1.0 gram
per cubic centimeter.
