Answer:
Soils are composed of mixtures of mineral and organic materials, but are classified according to the size of their mineral particles. The three main texture groups are sandy, silty, and clay.
Sandy soil contains particles that can be seen with the naked eye and feels gritty when rubbed between the thumb and forefinger. Sandy soils will generally not stick together when wet.
Silty soil contains particles, which are smaller than sand particles but larger than clay particles. Silt feels powdery when rubbed between the thumb and forefinger. Silty soil sticks together when wet, but will not hold its shape after it is dry.
Clay soil contains the smallest particle size. Clay particles form a sticky soil when wet and will generally hold a shape after drying. Soils are rarely composed of just sand, silt, or clay. They are usually a mixture of the three with a larger percentage of one size of particles.
Answer:
Depending upon the average grain-size and the conditions under which soils are formed and deposited in their natural state, they may be categorized into following types on the basis of their structure: In the grain-size classification, soils are designated according to the grain-size or particle-size. The more common classification systems are enlisted below: Geological Classification
Classification by Structure
Classification based on Grain-size
Unified Soil Classification System
Preliminary Classification by soil types
Based on the agencies responsible for their present state, soils may be classified under following types: Residual Soils
Transported Soils:
Alluvial or sedimentary soils
Aeolian soils
Glacial soils
Lacustrine soils
Marine soils.
Then you have inorganic and organic soils.

Which DNA-containing central cell structure found in plant and animal cells is absent in bacterial cells?
The DNA-containing central cell structure found in plant and animal cells is absent in bacterial cells is nucleus.
What is nucleus?The part of a cell that houses the chromosomes in biology. The membrane-enclosed nucleus is where RNA is synthesised from the chromosomal DNA.
DNA is organised into chromosomes in the nucleus, which is located in the centre of the cell.
The double nuclear membrane (outer and inner) that separates the nucleus from the cytoplasm, known as the nuclear envelope, envelops it. The rough endoplasmic reticulum and the outer membrane are one unit.
The nucleolus' main job is to facilitate ribosome biogenesis by assembling and digesting rRNA into preribosomal particles.
Bacterial cells lack the nucleus, the primary cell structure that houses DNA, that is present in plant and animal cells.
Thus, nucleus is only present is eukaryotic cells.

10. Which statement correctly describes the roles of mRNA and tRNA in protein synthesis?
A. tRNA delivers DNA code to the ribosome and mRNA delivers amino acids to the ribosome
B. mRNA delivers DNA code to the ribosome and tRNA delivers amino acids to the ribosome
C. tRNA delivers DNA code to the nucleus and mRNA delivers proteins to the ribosome
D. mRNA delivers DNA code to the nucleus and tRNA delivers proteins to the ribosome
Answer:
The right answer is D.
Explanation:
The messenger ribonucleic acid, messenger RNA, or mRNA is a transient copy of a portion of the DNA corresponding to one or more genes. mRNA is used as an intermediate by cells for protein synthesis. Jacques Monod, François Jacob, and their collaborators issued and showed the concept of messenger RNA in 1960.

A farmer uses DDT to kill insects in his field. The first year nearly all of the insects were killed. By the fourth year, however, nearly all of the insects survived the DDT treatment. Explain the process of natural selection in this population of insects. Include these words - mutation, phenotype, variation, resistance, adaptation, and differential survival.
Answer:
Explanation:
Selection is the greatest force that alters gene frequency and brings about variation that is evidence in a population. There are both natural and artificial selection.
Mutation is one of the force that alters population frequency it is an heritable change that is sudden and occur in the gene, it can be induced or caused naturally.
The insect survived the DDT used because over the years they have build immunity and resistance against the chemical, they now mutate and produce gene that becomes resistance to the chemical and now adapted or adaptable to the environment. Natural selection helps in the continuous perpetuation of the new phenotype and a new differential survival rate.

Answer:
If an organism is able to survive the increase in airborne toxins and reproduce, there is a high chance that their offspring will also be able survive in airborne toxins, although some may not. But all the organisms that can survive and reproduce will produce more and more organisms that are able to survive from an increase in airborne toxins.

Could artificial selection occur without natural variation?
Answer:
In artificial selection, nature provides the variations, and humans select those they find useful. No because inherited variation occurs out of everything or occurs in all breeding.

Explain how the availability of resources in the environment is linked to exponential growth of a species
Answer: Exponential growth occurs when resources in the environment are abundantly available to a species.
Explanation: When a food source amount drops, so does the survival rate of the predator that eats that specific food source. When a food source grows too abundantly at too fast a rate, predators increase in numbers.

Answer:
The Gulf Stream is caused by a large system of circular currents and powerful winds, called an oceanic gyre.
