Answer:
His observations that chromosomes double is significant to the later-discovered theory of inheritance. ... His discoveries, known as Chargaff's Rules, proved that guanine and cytosine units, as well as adenine and thymine units, were the same in double-stranded DNA, and he also discovered that DNA varies among species

What is the source of sediment? A. fragments of other rocks B. chemicals and minerals dissolved in water C. sea shells D. all of the above
Answer:
D: All of the above
These are all sources for sediments
The correct option is D. all of the above are a source of sediments.
What are sediments?
According to geologists, sediment is any solid Earth surface material that can be transferred and dumped in a new location, whether it be on land or in water.
Because sediment particles are easily picked up by water, wind, and ice and transported to new locations, erosion is a significant driver of sediment mobility.
Pebbles and gravel are deposited further downstream, notably in lowland deltas where river mouths open up to the ocean, as water runs over land and through the creek and river basins.
Therefore, The correct option is D. all of the above are a source of sediments.

Each parent gives one of these to the offspring to form a genotype.
Answer: Alleles
Explanation: Genes come in different varieties, called alleles. Somatic cells contain two alleles for every gene, with one allele provided by each parent of an organism.
Each parent gives one ALLELE to the offspring to form a genotype.
An allele is a gene variant. which is inherited from each parent.
During fecundation, each parental gamete provides a different allele of a given gene/locus in order to form the genotype of an individual.
If both parents provide the same allele of a given gene/locus, then the individual is homo-zygous for that gene.
If both parents provide different alleles of a given gene/locus, then the individual is heterozygous for that gene.
In conclusion, one allele is inherited from the mother and the other allele from the father.

Answer:
A tumor :) i just ask my biology teacher
The mass of cells formed a result of accelerated rate of division is called tumour.
CELL DIVISION:
All living cells are capable of replicating themselves and this is done via the process of cell division. However, the rate at which cell division occurs must be regulated.Due to series of reasons like mutation, cells can lose the ability to regulate their cell cycle leading to a proliferation in the rate of cell division. Uncontrollable increase in the rate of cell division leads to the formation of a mass of cells called TUMOUR. Therefore, a mass of cells formed a result of accelerated rate of division is called tumour.Learn more: https://brainly.com/question/24155890?referrer=searchResults

Recognize what energy is and how it is transferred throughout living systems.
Explanation:
Energy is the ability to do work. There are two main forms of energy, potential and kinetic energy.
Potential energy is the energy at rest in a body
Kinetic energy is the energy due to motion
Energy is usually transferred throughout living systems when are transformed from one form to another. For example, chemical energy in food produced by plants is taken by animals as food. They then convert the chemical energy into other forms of energy like heat energy which they use for their daily activities.What are volume and density? How do they relate to each other?

Using the information in the Periodic Table, it is possible to determine that atoms of the
Answer:
D . The atomic number and atomic mass decrease from left to right across a period;
energy levels increase from top to bottom down a group.
Explanation:
On the periodic table, elements are arranged based on the periodic law. This law states that "the properties of elements are a periodic function of their atomic number".
The atomic number is the number of protons in an atom.
Atomic mass is the number of protons and neutrons in an atom
The energy level is the number of shells in an atom
As we move from left to right on the periodic table, both atomic mass and atomic number increases. Also, down a group, the energy level increases as the number period increases. From left to right, the energy level stays the same.
