Which statement best describe a chromosome?
A. It is a single piece of DNA that contains genes.
O B. It forms the hereditary material of all life on Earth.
OʻC. It is the passing of characteristics from one generation to the next.
O D. It is the part of a chromosome that ties together two chromatids.
Answer: A
Explanation: It most definetly not B, becuase not every form of life has DNA. A chromosome is a single chain of DNA that is coiled and super coiled to form dense thread-like pieces. The term chromosome is derived from the Greek words "chroma" or color and "some" or body and is so named because chromosomes have the ability to be stained with dyes.

Which of the following statements explains the importance of enzymes that check for and repair mistakes during DNA replication?
A
The enzymes replace the DNA with RNA
B
The enzymes speed up the rate of RNA synthesis.
C
The enzymes prevent many genetic mutations from being expressed
D
The enzymes remove many recessive gene copies from the nucleus.
Answer:
C!!
Explanation:
The statement explains the importance of enzymes that check for and repair mistakes during DNA replication is the enzymes prevent many genetic mutations from being expressed. Thus, the option C is correct.
What is RNA polymerase?RNA polymerase is an enzyme that aids in the transcription of DNA into RNA during transcript in the nucleus. The enzymes prevent many genetic mutations from being expressed.
Primase is an enzyme that synthesizes short RNA sequences called primers. These primers serve as a starting point for DNA synthesis during replication as the DNA polymerases cannot begin the synthesis of the new strand, they only extend it after primase begins it and primase produces RNA molecules, the enzyme can be said to be a type of RNA polymerase.
Therefore, The statement explains the importance of enzymes that check for and repair mistakes during DNA replication is the enzymes prevent many genetic mutations from being expressed. Thus, the option C is correct.

what is needed for dna replication
Answer:
enzymes
ATP energy
nucleotides
Explanation:
All of the above are needed. Nucleotides are the basic building blocks of new DNA, ATP energy is needed because replication is an active process, and enzymes catalyze the reactions needed to carry it out (e.g. helicase to separate the strands to be replicated, DNA polymerase to build the new strands, and ligase to "glue" the fragments together).

Use your knowledge of osmosis to explain why the mass of each cube increased.
Osmosis passes from a medium with a high concentration of water molecules to another with a low concentration of water molecules and since the potato has low water concentration so the water transfers to it increasing its mass
The mass of each potato cube increased because they have gained water by osmosis.
Recall that: osmosis is the movement of water molecules from the region of high water concentration (high water potential) to the region of low water concentration (low water potential) through a semipermeable membrane.
A solution with a high solute concentration will have low water potential and vice versa. They are also said to be hypertonic when compared to a solution with a low solute concentration (hypotonic).
Thus, the potato cubes increased in size because the cells of the potato have low water potential when compared to the distilled water in which they were thrown. In other words, the cell sap of the potato cubes is hypertonic while the distilled water is hypotonic.

Answer:
A. Individual organisms are able to change their genetic adaptations in
order to better survive in changing environments.
Explanation:
Natural selection can be defined as a biological process in which species of living organisms having certain traits that enable them to adapt to environmental factors such as predators, competition for food, climate change, sex mates, etc., tend to survive and reproduce, as well as passing on their genes to subsequent generations.
Simply stated, natural selection entails the survival of the fittest. Therefore, the species that are able to adapt to the environment will increase in number while the ones who can't adapt will die and go into extinction.
The statements which are consistent with the concept of natural selection includes;
I. More offspring are produced than can survive in an environment (overproduction of offspring). This ultimately implies that, the more offsprings that are reproduced by the parent organism, the more likely are they to survive.
II. There is genetic variation within populations. This simply means that tere is a better chance of having good or beneficial traits being passed from the parent organism to her offsprings.
III. Organisms with beneficial variations are more likely to survive and reproduce, as well as passing on their genes to subsequent generations.

What are the 5 main functions of soil? List and describe each
Soil covers the surface of the Earth and is a valuable ecosystem. Soil is made up of minerals, nutrients, water, air, organic matter and microorganisms. Because of its makeup, soil has a variety of uses in a variety of industries.
Agriculture
Soil has vital nutrients for plants. As a result, it is used in agriculture to nourish plants. The roots of a plant receive nutrients from the soil to help it grow. The North Carolina Department of Agriculture and Consumer Services notes that 13 essential plant nutrients come from the soil.
Building
Soil is an important part of the building process. Soil compaction, which increases the density of the soil, is done as part of the building process. The purpose of the compaction is to improve the load support. If not done, structural failure can result. Soil can also be used as building materials such as adobe and red bricks.
Pottery
Clay soil is used in making ceramics, or pottery. When water is added to clay soil, it can be used to create the ceramics. Once formed, you can leave it to dry and it will retain its shape. Any type of ceramic can be created with the clay soil, such as a vase, bowl, cup or sculpture.
Medicine
Soil is commonly used in antibiotics. Microbes created in the soil are harmful to bacteria, which is why soil is used in medicine. Medicines created by soil include skin ointments, tuberculosis drugs and anti-tumor drugs.
Beauty Products
Some beauty products are made with soil. Commonly used beauty products where used soil is used in the production include blush and foundation. Soil rich in clay can also be used in facial masks and toothpastes.
The main function of the soil is to serve as a seat, facilitate the permeability and circulation of water and air, being important for plant life.
What is soil?It is the layer that covers the most superficial part of the planet and it is where plants grow and animals live.
Functions of soilBiomass production.It supplies water, air, and nutrients to plants, provides food, energy, raw materials, and natural traits.
Hydrological function.It intervenes in the regulation of infiltration, storage and flow of surface and subsurface water and its quality.
Environmental function of filtering, storage and transformation.Filtering, pH buffering, retention of hazardous waste compounds and polluting discharges, etc.
Biological habitat and gene pool.Reserve of genes of animals and plants essential for the maintenance of biodiversity.
Wheater regulating function.Sink of greenhouse gases and effects on the global energy balance and the global hydrological cycle.
Therefore, we can conclude that soils acts as a filter, buffer medium and storage of water, air, nutrients and chemical products or discharges.

How did the temperature relate to the “recommended temperature limit” (solid horizontal red line)?
Will give extra points for right answer or explanation
Answer:
The “recommended temperature limit” represents limit of the temperature that is good for our world.
Explanation:
The temperature related to the “recommended temperature limit” means that in the graph there is a limit of temperature for our world's environment. if the temperature is between this limit, there is less or no adverse effect on our environment while on the hand, if the temperature exceeds from this limit, then it adversely affected our world because the emission of carbondioxide gas in the atmosphere increases due to this increase temperature..
