Answer:
With a BB homozygous the probability of a gamete having the B allele is 100%, and no chance of having the b allele.
Explanation:
For a given trait, B represents the dominant allele, while b is the recessive one. The fact that an individual has a homozygous (dominant) form for this trait means that their homologous chromosomes contain the B allele and, therefore, his gametes can only have the B allele.
In the case that the individual was heterozygous, the chances of having a gamete with B or b would be 50:50.

Answer:
Radiocarbon dating
Explanation:
Radiocarbon dating measures radioactive isotopes in once-living organic material instead of rock, using the decay of carbon-14 to nitrogen-14. Because of the fairly fast decay rate of carbon-14, it can only be used on material up to about 60,000 years old.
Answer:
D. Changing land use and burning fossil fuels.
Explanation:
Today, the carbon cycle is changing. Humans are moving more carbon into the atmosphere from other parts of the Earth system. More carbon is moving to the atmosphere when fossil fuels, like coal and oil, are burned. More carbon is moving to the atmosphere as humans get rid of forests by burning the trees.
Answer:
A. inheritance and reproduction
Explanation:
These two terms are interrelated as the act of one (reproduction) gives rise to the other (inheritance). The process whereby offsprings are produced using gametes (sexual reproduction) or without gametes (asexual reproduction) from a an organism called the parent is called REPRODUCTION. Reproduction is necessary to ensure the survival of a particular species.
During reproduction, the genetic material (DNA) in form of chromosomes of an organism is passed down from parents to offsprings in a process called INHERITANCE or HEREDITY. The information needed for certain processes like growth, reproduction, survival and others are contained in the genetic material, and are transferred from the parents to their progenies.
In sexual reproduction, this biological information encoded in the genetic material is passed on via gametes produced by each parent (male and female) during meiosis.
