Answer:
False
Explanation:
Mass and volume are two different quantities. In fact:
- Mass is a scalar quantity representing the "amount of matter" contained in a certain substance. It is measured in kilograms (kg), which is one of the 7 fundamental SI units.
- Volume is a scalar quantity representing the amount of "three-dimensional space" occupied by an object or a substance. It is measured in cubic meters (
).
Therefore, mass and volume are two different quantities. They are related through another quantity called density, given by:
where
m is the mass
V is the volume
So the density of a substance represents the amount of mass contained in a certain volume of the substance.
Answer:
Insecta
Explanation:
The classification levels are the following from broadest to the most specific:
Domain
Kingdom
Phylum
Class
Order
Family
Genus
Species
In your selection it is listed in that order:
Domain --- Eukarya
Kingdom --- Animalia
Phylum --- Arthropoda
Class --- Insecta
Order --- Hymenoptera
Family --- Apidae
Genus --- Apis
Species --- Mellifera
When you name the organism, we use the two name or binary naming system, getting the genus and the species. So the scientific name of the honey bee is: Apis mellifera
Ans.
Sex-linked genes are those genes that found on sex-chromosomes (X and Y chromosomes) and their phenotypic expression for a trait depends on the gender of the offspring.
Most of the sex-linked genes are present on X chromosomes as X chromosomes have more number of genes as they are made up of more DNA as compared to Y chromosome.
However, male individuals are more likely to exhibit the sex-linked traits. It is because most of the sex-linked traits are recessive and males have only one copy of X chromosome, while females have two copies of X chromosome. One mutated copy in male can exhibit the trait, while in females, both of the mutated copies are required to exhibit that trait.
Answer:
Option C, Plant A
Explanation:
Control group within an experiment is the substance/organism or subject which shall enact as a base for comparison of impact of experiment created on the dependent variables.
Here, the impact of fertilizer is to be studied on plant. Thus, plant set up is dependent variable and amount of fertilizer is an independent variable. Out of all plants one plants is getting 0 amount of fertilizer hence this plant can be used for comparison with other plants which receives the fertilizers.
That would be true.
The biomass and amount of energy and number of individuals is decreased as we go up the trophic levels.
