which best describes a gene?
Answer:
Asegment of chromosomal DNA
Explanation:
A gene is a hereditary unit consisting of a sequence of DNA that occupies a specific location on a chromosome and determines a particular characteristic in an organism. Genes undergo mutation when their DNA sequence changes. It is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. However, many genes do not code for proteins. Alleles are forms of the same gene with small differences in their sequence of DNA bases. These small differences contribute to each person's unique physical features.

What happens when magma cools during the rock cycle? Igneous rock is formed. Metamorphic rock is melted. Sediments form sedimentary rock. Metamorphic rock forms sediments.
Answer: igneous rock is formed
Explanation:
When magma cools down during the rock cycle then igneous rock is formed. Thus, the correct option is A.
What are Igneous rocks?Igneous rock is one of the three main rock types, while the other being sedimentary and metamorphic rocks. Igneous rocks are the rocks formed through the cooling and solidification of magma or lava from volcano. The magma can be derived from partial melts of existing rocks in either a planet's mantle or the crust.
Lava from the volcano cools to form volcanic rock as well as volcanic glass. This magma can also extrude into Earth's atmosphere as part of a violent volcanic explosion. This magma then solidifies in the atmosphere to form volcanic rock called as tephra. In the atmosphere, tephra is more often called as volcanic ash.
Therefore, the correct option is A.

Explanation:
if an organism has a diploid number of 12, how many possible combinations of chromosomes could exist in its gametes with no crossing over?
a.) 8
b.)16
c.)32
d.)64
Answer: D
Explanation:
Chromosomes are the inherited unit of the organism which transfers the parental gene to the offspring.
The diploid is the paired chromosome quantity present in the cell that originates from each parent.
The correct answer is:
Option D. 64
This can be explained as:
The diploid (2n) number of chromosomes = 12Haploid (n) number of chromosome = 6The possible number of chromosome pairs is given by 2ⁿ. Where n = a haploid number of chromosomes.So, the possible combinations of chromosomes that could be found in the gametes with no crossing over will be:
= 2⁶
= 64
Therefore, 64 possible combinations of chromosomes can be present.

1)) The average depth of a lake is 10 meters. Do you think sunlight acts a limiting factor the same way it does in the ocean? Why or why not?
2)An area with a high population of crayfish in local lakes and rivers has begun experiencing acid rain, rain that has a pH of 3.0 - 4.0. Predict how this rain will impact the crayfish population.
Answer:
No.
Explanation:
No, the sunlight does not act as a limiting factor the same way it does in the ocean because the lake has lower depth as compared to ocean which is very deep i. e. more than 3000 meters where sunlight does not reach and we know that sunlight is very important for the survival of plants. Sunlight reach in the water about 1000 meters so plants can survive and do photosynthesis due to its low depth.
Acid rain will impact the crayfish population because acid rain decreases the pH of water and this lower pH causes death of the crayfish and also the food of crayfish and thus lower the population of crayfish due to unavailability of food..

What does an organism's genotype describe?
the allele combination for a trait
the physical appearance of a trait
the number of alleles on a gene
the number of different traits inherited
Answer:
the allele combination for a trait
Explanation:
The genotype describes which alleles (versions) of a gene an organism has. Diploid organisms, such as humans, have two copies of each gene. Sometimes these alleles are the same and the individual is h0m0zygous for that gene. If they are different, the individual is heterozygous for that gene.
The physical appearance of a trait is the phenotype.

Answer:
Any living creature that lives beneath the Pacific surface will absorb the sunlight for nourishment. If the sun banishes all the living organisms (plants and algae) will suffer due to the lack of photosynthesis. The sun has a massive effect on the aquatic life in the oceans, lakes, or any body of water; including the Pacific Ocean.

What is different about normal cell division and cancer cell division?
Answer/Explanation:
Normal cell division is a very controlled process.
There are several checkpoints where the cell ensures the cell is:
receiving the correct signals to dividethat the environmental conditions are favourable for the cell to dividethat there is no damage to the DNA.However, cancerous cells proliferate uncontrollably. This is because they can bypass the checkpoints and divide without the necessary signals. This means cell division keeps occurring even when conditions are unfavourable and the DNA is damaged.

Answer:
The higher the density, the more closely packed the particles called atoms and molecules. The lower the density the more spaced muy the particles are
If density = mass divided by volume, than the more volume a material has the less dense it is. For example, if there are five people in a room that is 5ft. by 5ft. the people will be tightly packed together and more dense. If those same five people were in a room that is 20ft. by 20ft. they would have more space and it would not be as dense in the room.

Sam does an experiment in his lab. He discovers that the mass of the reactants before his
experiment is the same as the mass of the products after his experiment. What did he prove?
Answer:
The law of conservation of mass
Explanation:
In the given scenario of the experiment, Sam is proving here the law of conservation of mass.
What is law of mass conservation?The law of conservation of mass basically implies that mass can neither be created nor be destroyed in any chemical reaction.
When coal is burned, for instance, the carbon atom altered into carbon dioxide. The carbon atom changes from a solid to a gas, but its mass remains constant.
The law of conservation of mass is a fundamental physics principle. In other words, no matter how the parts are rearranged, the mass of an object or collection of objects remains constant.
The law of conservation of mass was critical to the advancement of chemistry because it helped scientists understand that substances did not vanish as a result of a reaction, but rather transformed into another substance of equal mass.
Thus, here Sam is demonstrating law of mass conservation.
