A Logging removes trees from a hill, leaving a barren landscape.
Classification:
Explanation:
Answer:
Sediment pollution
Explanation:
There is no more vegetation on the hill to prevent sediment from being carried away
Logging removes trees from a hill, leaving a barren landscape is sediment pollution.
Pollution refers to any contamination of the natural environment with unwanted material or energy which renders the environment unfit for life. There are many kinds of pollution that affect various spheres of the environment such as land, air water etc.
When trees are logged from a hill in such a manner that the landscape is left barren, sediments can now easily be washed away by runoff into surrounding water bodies or other areas. This is an example of sediment pollution.

In a plant, leaf color and leaf shape are controlled by two linked genes. Leaves of the wild plant are red (R) while a recessive mutation in this gene causes leaves to be white (r). Wild-type leaves are pointed (P), while a recessive mutation in this gene causes them to be smooth (p). For a parent plant that is heterozygous for both traits with both recessive mutations on one chromosome, what genotypes will its gametes be
Answer:
The genotypes of the gametes are:
RP (parental), rp (parental), Rp (recombinant), rP (recombinant)
Explanation:

Answer:
rRNA - Ribosomal RNA, a molecular component of a ribosome, the cell's essential protein factory. Strictly speaking, ribosomal RNA (rRNA) does not make proteins. It makes polypeptides (assemblies of amino acids) that go to make up proteins
tRNA - Transfer ribonucleic acid (tRNA) is a type of RNA molecule that helps decode a messenger RNA (mRNA) sequence into a protein. tRNAs function at specific sites in the ribosome during translation, which is a process that synthesizes a protein from an mRNA molecule.

What is the difference between domestication and natural selection?
Answer:
By definition, natural selection is the survival of the fittest.
Explanation:
Natural selection, in itself, is not a generator or creator of evolutionary novelties, but it only exposes certain variants.
Variants do not arise under the induction of the environment, but randomly, by chance, by a combination of genetic material, something that already exists in the genetic fund of a species.
Domestication is a term used for the process by which various biological organisms adapt to survive in society or through the work of human beings.

Which event in meiosis increases genetic variation within a population?
A. DNA condenses to form chromosomes.
B. Segments of chromosomes cross over.
C. Chromosomes duplicate themselves.
D. Chromosomes form pairs.
Answer:
Because of recombination and independent assortment in meiosis, each gamete contains a different set of DNA. This produces a unique combination of genes in the resulting zygote. Recombination or crossing over occur during prophase 1

Which of the following correctly summarizes the development of the fetus during the second trimester?
Body functions, reflex development, and skin details
Cell division and tissue specialization
Gastrulation, neurulation, and rhythmic breathing
Specialization, function, and growth
Answer:
Body functions, reflex development, and skin details
Explanation:
The second trimester marks the period between the thirteenth to the twenty-sixth week. During this period of fetal development, the fetus begins reflex development such as sucking and swallowing. He is also now able to respond to stimuli.
Body functions are also developing at this stage. The baby can now kick, turn, and move his body. The brains are developing, the hairs and fingernails are also beginning to develop.
Skin details are also developed at this stage. For example, the vernix caseosa is produced to protect the skin of the fetus.

What is the role of energy in living organisms? Is ti a mor or less important role than other characteristics of life?
Answer:
A huge number of chemical reactions take place continuously in a living cell. The whole of all chemical processes, that is, the total turnover of matter and energy is called metabolism.
Explanation:
All organisms need the energy to grow, reproduce, and respond to their surroundings. All these processes are achieved through metabolism that allows the energy available to them.
