Answer:
A. Mendel observed green and yellow pea pods in a 3:1 ratio because the F1 generation was heterozygous.
Explanation:
The two true breeding plants in the parental population were homozygous (that is what true breeding means). Therefore, their cross would lead to all heterozygous offspring (see attached punnet square). Green is the dominant characteristic, so all F1 plants had a green phenotype, but Gg genotype.
The F1 cross would therefore be Gg x Gg. See attached punnet square.
The genotypes in the F2 generation are 1 GG: 2 Gg: 1 gg 1
Therefore, the phenotypic ratio is 3 green pea pods (Gg or GG): 1 yellow (gg)
Complete Question:
Which Kingdom of living things consists entirely of multi-celled, heterotrophic organisms?
A) Animal
B) Fungi
C) Plant
D) Protist
<u>Correct Option:</u>
<u>Animal</u> Kingdom of living things consists entirely of multi-celled, heterotrophic organisms.
Option: A
<u>Explanation:</u>
The system of scientific classification in biological science is categorized into seven main groups: kingdom > phylum > class > order > family > genus > species. Here the kingdom is the largest group while smallest is the species. The term phylum is being used in the Kingdom of Animals, and is the second largest group.
The Kingdom of Animals is made up of multi-cellular, heterotrophic species which feed on other entities to survive. Some of the animal properties in this kingdom are able to establish, function independently, and reproduce during their existence.
Carbon would be the answer to this because it is an element while water is a compound. In addition, carbon had 4 bonding sites which allows it to form a variety of molecules like sugars, proteins, and even DNA that are essential for life as we know it.

Explanation:
Protons are positively charged sub-atomic particles that are in the nucleus of an atom and have a relative mass of 1. Neutrons have a neutral charge, meaning they have no charge, and are also in the nucleus of an atom with a relative mass of 1.Electrons are negatively charged particles that orbit the nucleus in electron clouds. They are said to have a relative mass of 0.
For example, a sodium atom is number 11 on the periodic table. The atomic number of sodium tells us the no. of protons contained within its nucleus as well as the number of electrons orbiting. So we can say that sodiun has 11 electrons and 11 protons. To determine the number of neutrons, simply subtract the number of protons from the mass number( found on periodic table)
23-11=12 neutrons
