Answer 2

Hair is not considered a living thing. Hair is composed of dead cells that are produced by living cells in hair follicles.

Is hair a living thing?

Hair is primarily made up of a protein called keratin, which is produced by specialized cells within the hair follicles. These cells, called keratinocytes, undergo a process of differentiation as they move upward through the hair follicle, eventually becoming fully keratinized and forming the hair shaft. Once the hair shaft is fully formed, it no longer possesses any metabolic or cellular activities. It lacks a blood supply, nerve endings, and other cellular structures that are characteristic of living tissues.

While hair itself is not alive, the hair follicles that produce hair are living structures and play a crucial role in hair growth and maintenance. Hair growth occurs in cycles, with each hair follicle going through a growth phase (anagen), a transitional phase (catagen), and a resting phase (telogen). During the anagen phase, the hair follicles actively produce new hair cells, which eventually become part of the hair shafts.

Answer:

1. cedar, mango and pine

2. elm and maple

3. pine and cedar  

4. mango, elm and maple

Explanation:

Evergreen trees are plant tree species that remain green across seasons, even in cold/dry conditions, thereby contrasting with deciduous trees that lose their leaves in cold/dry conditions.  Conifers (Coniferophyta) are gymnosperm plants that produce seeds without fruit/flowers. Conifers are vascular land plants composed of one that one class named Pinopsida, which consists of perennial plants with secondary growth. Moreover, mango, elm, and maple are hardwood trees that have seeds within fruits (i.e., they are angiosperms), which lose their leaves seasonally (i.e.,  they are deciduous trees).

Which of the following describes a non-sense mutation?
A.Base pair change results in a premature stop codon; protein is nonfunctional.

B.Base is changed but the resulting amino acid is the same as in the non mutant DNA. No outward changes
.
C.A base is either added or deleted and causes the codons to be read incorrectly.

D.Base pair change results in a different amino acid; this may or may not affect the protein that result.

Answers

Answer:

A.Base pair change results in a premature stop codon; protein is nonfunctional.

Explanation:

Mutation, generally, refers to any change that occurs to the genetic sequence of a DNA. It can occur in different forms, hence, has different types. One particular type is the base pair substitution mutation, which involves the replacement of one or more nucleotide base by another in a sequence.

Base pair substitution can either result in one of the following namely: silent, missense, and nonsense. In NONSENSE mutation, the replacement of bases in the sequence causes the translation process to stop because a STOP CODON is prematurely encountered. Hence, the protein is non-functional.

Wernicke's aphasia.

a double dissociation.

Broca's aphasia.

a single dissociation.

Answers

Answer:

a double dissociation.

Explanation:

Double dissociation is a psychological term used to describe a scenario whereby two mentally concerned processes are independent in function i.e they work specifically for different functions. In double dissociation, damage to one neurological (brain) area affects only one of two functions and have no effect on the other.

This is the case in this question where a neurologist noticed that damage to brain structure A of a patient resulted in a major disruption in speech production, but left hearing ability intact while a damage to structure B in another patient left major hearing impairment, but did not affect speech production. This example portrays what DOUBLE DISSOCIATION explains.

Why do some organisms make one type of protein for a feature while other organisms make two? RIGHT ANSWER GETS CROWN

Answers

Answer:

For every gene, there may be several possible versions. Different genes carry instructions for making different proteins. If the gene copies are heterozygous, two types of protein are produced, if the gene copies are h0m0zyg0us, one type of protein is produced.

Explanation:

Every gene has several variants. Genes encode proteins. If the gene copies are heterozygous, two types of protein are produced; if they are homozygous, one type of protein is produced.

What is a gene?

DNA, or in the case of certain viruses, RNA, is the medium in which an organism's genome is written. A gene is a section of the genome that contains the genetic instructions for making a particular protein or RNA. Codons are units of three nucleotides in a gene that each code for a specific amino acid. Genes that code for proteins are made up of these codons.

There might be multiple variants of each gene, depending on the circumstances. Instructions for the production of a variety of proteins are contained within each gene. If the gene copies are homozygous, then only one type of protein will be produced; however, if the gene copies are heterozygous, then two different types of protein will be produced.

The incidence of V. vulnificus infections is increasing, especially in northern parts of the United States, compared to 20 years ago. Can you think of any reason why this might be happening?

Answers

Answer:

The effects of climate change may be associated with the increased incidence of V. vulnificus infection

Explanation:

Vibrio vulnificus is a harmful bacterium that causes a serious disease due to eating contaminated seafood, which is the main cause of seafood-related deaths in the USA. V. vulnificus is naturally present in the flora of coastal waters around the world and this bacterium has been isolated from a variety of seafood (e.g.., fish, oysters, shrimp, etc). Epidemiologic studies have shown that the incidence of V. vulnificus infection has increased dramatically since 1996. During this same period, climate change has been responsible for the increase in salinity and temperature of the coastal waters (i.e., the natural habitat of this bacterium). In consequence, it is reasonable to suppose that the change in climatic conditions may be associated with the increased incidence of V. vulnificus infection.

Is an ionic bond more like a polar covalent bond or a non-polar covalent bond? Explain

Answers

Answer:

POLAR

Explanation:

The formation of an ionic bond is the result of the transfer of one or more electrons from a metal onto a non-metal.

Non-polar is an equal sharing of electrons, whereas polar is an unequal sharing of electrons.

Ionic bonding is on one extreme with a complete transfer of electrons forming charged ions. Non-polar covalent bonding with equal sharing of electrons is at the other extreme.

Even though ionic bonding is kinda in the middle, it leans more towards polar because they aren't two opposite extremes.

Should Marijuana be legalized? Why or Why not?

Answers

Marijuana is only not legalized to incarcerate minorities, predominantly Mexican/Black people. At the turn of the 20th century, cannabis, as it was then commonly known in the United States was a little-used drug among Americans. With the start of the Mexican Revolution in 1910, many Mexicans began moving to the United States, and they brought with them the tradition of smoking marijuana. Anslinger (1930s Harry J. Anslinger, head of the Federal Bureau of Narcotics) sought a federal ban on the drug, and to this end he initiated a high-profile campaign that relied heavily on racism. Anslinger claimed that the majority of pot smokers were minorities, including African Americans, and that marijuana had a negative effect on these “degenerate races,” such as inducing violence or causing insanity. Quite ironically Marijuana is less harmful than alcohol, and that adults should have a right to use it if they wish. Marijuana could also help with medical complications such as Anxiety and “chronic pain that plagues millions of Americans, especially as they age. Part of its allure is that it is clearly safer than opiates (it is impossible to overdose on and far less addictive) and it can take the place of NSAIDs such as Advil or Aleve, if people can’t take them due to problems with their kidneys or ulcers or GERD” said Harvard University.
