Explanation: just took the test and got it right
This cancer is the direct result of a mutation in the genetic material.
What is Mutation?Genetic mutations, which occur as your cells divide and generate duplicates of themselves, are modifications to your DNA sequence. Your DNA teaches your body how to develop and work.
Genetic changes may result in diseases like cancer or, in the long run, may enable people to adapt to their environment more successfully.
A change in the DNA sequence is referred to as a genetic mutation. Your cells receive the information they require to carry out their functions from your DNA sequence.
Therefore, This cancer is the direct result of a mutation in the genetic material.

- What is the ultimate process that moves the tectonic plates?
A. Gravitational Forces
B. Convection
C. Solar Winds
D. Unknown - Still Investigating
Answer:
I would say B - Convection
Explanation:
it is volcanos and earthquakes that move the tectonic plates... but those act like convection currents...
-Solar Winds come from the Sun and they are reflected off of Earth's magnetic shield so that can't be correct.
-Gravitation does play a role yes but I can not say that it actually causes it... (Gravity holds everything in orbit and also together... and it helps keep things on Earths surface -it is the reason why we can still breath-)
-Unknown - Still Investigating, The reason why the tectonic plates move "was" discovered... or at least it is believed to have been. But I do not doubt that they are still studying it... because they probably are still investigating
-The convection currents move the plates. Where convection currents diverge near the Earth's crust, plates move apart. Where convection currents converge, plates move towards each other.
I have a nice day and I hope it helps!

c. Genes are partly in chromosomes and partly in DNA.Genes are partly in chromosomes and partly in DNA.
d. There are sections of chromosomes that are not genes.There are sections of chromosomes that are not genes. , ,
Answer:
A chromosome is made of a very long strand of DNA and contains many genes (hundreds to thousands). ... The genes on each chromosome are arranged in a particular sequence, and each gene has a particular location on the chromosome (called its locus).
Explanation:
Human gametes should contain chromosomes each. This number would be considered the
(haploid/diploid) number for humans. The symbol for this is
Answer:
Human gametes should contain 23 chromosomes each. This number would be considered the haploid number for humans. The symbol for this is n.
Explanation:
Gametes are an organism's reproductive cells. Female gametes are called egg cells, and male gametes are called sperm.
In most organisms, somatic cells (all cells except for gametes) are diploid, whereas the gametes tend to be haploid. Haploid cells have a single set of chromosomes, while diploid cells have two sets of chromosomes.
When it comes to human cells, somatic cells have 46 chromosomes. This means that each gamete has 23 chromosomes. This is called the haploid number and is marked by a lowercase n. This number refers to the total number of chromosomes found in a gamete (for human cells n=23).

Water molecules have select answer a lesser a greater an equal attraction for sodium and chloride ions than sodium and chloride ions have to each other.
Answer:
A greater attraction
Explanation:
Water molecules have A GREATER ATTRACTION for sodium and chloride ions than sodium and chloride ions have to each other.
This is because when salt is added to water, it dissolves, which depicts the level of the covalent bond of water is stronger by separating the ionic bond between sodium and chloride, otherwise, the salt would not have been able to dissolve.
The habitat of a rattlesnake is the hot, dry desert. Could this organism live in the
cold, Artic habitat? *
Answer:
No, a rattlesnake would not be able to survive in the Arctic. This reptile is specially equipped with features suited to a hot desert, which would be a hinderance in a cold desert rather than an advantage. Also cold-blooded organisms must be able to bask in the sun to maintain a stable body temperature, but in the Arctic, that wouldn't be possible.

Which statement best describes a difference between saturated fats and unsaturated fats?
A. Unsaturated fats tend to have higher melting points because they have only single carbon-carbon bonds, which allow the molecules to be straight.
B. Unsaturated fats tend to have lower melting points because they have at least one carbon-carbon double bond, which causes the molecule to bend.
C. Unsaturated fats tend to have lower melting points because they have only single carbon-carbon bonds, which allow the molecules to bend.
D. Unsaturated fats tend to have higher melting points because they have at least one carbon-carbon double bond, which causes the molecule to be straight.
Answer:
B.
Explanation:
Unsaturated fats are fats that have one or more carbon-carbon double bond in their chain. The double bond causes the molecule to bend. The molecules do not stack well, which causes the intermolecular forces to be much weaker than those of saturated fats. This causes the melting points to be lower for unsaturated fats.
Hope that helps.
The statement that differentiates unsaturated and saturated fats is "Unsaturated fats tend to have lower melting points because they have at least one carbon-carbon double bond, which causes the molecule to bend".
WHAT IS SATURATED AND UNSATURATED FATS?
Saturated fats are a type of fats that lack carbon to carbon double bonds in their structure, however, in unsaturated fatty acids, there is at least one double bond in the chain. Due to the double bonds possessed by unsaturated fats, their molecules tend to bend structurally. Unsaturated fats are mostly liquids at room temperature, as opposed to saturated fats which are solids. Hence, unsaturated fats will possess a low melting point compared to saturated fats.Therefore, Unsaturated fats tend to have lower melting points because they have at least one carbon-carbon double bond, which causes the molecule to bend.

C. Genes are located inside the nucleus, and chromosomes are located outside the nucleus .
D. Chromosomes are located inside the nucleus and genes are located outside the nucleus
maceus
Answer:
A. Genes are found within chromosomes.
Explanation:
A chromosome is a single linear, coiled DNA molecule that contains part or even all the genetic material of an individual. On the other hand, genes are chromosomal segments that contain the instructions required to encode a specific protein, which is stored in the form of a sequence of nucleotides. In consequence, a chromosome may have many genes. In biology, a gene is considered to be the basic physical and functional unit of heredity.
