when you move your hand up and down while holding on a jump rope, you make a wave. What is the medium
Answer:
The medium of the wave is the Rope.
Explanation:
This is because it is transverse wave and transverse wave need a medium to transfer energy and this is because in transverse wave,particles of the medium move in a direction that is perpendicular to the direction of the transverse wave. From the question, when you move you hand up and down, you make a wave and the direction of the wave is also up and down which is perpendicular to the direction of the wave.
The second farmer used Technique B: Used a genetically modified variety of corn. The plant produces an insecticide which selectively kills only the moth larvae as it feeds on the corn. What is a likely impact on the farmer of growing such a variety of corn?
A) The financial costs for the farmer would be lowered since LESS crops would be lost to pests.
B)The financial costs for the farmer would be lowered since MORE crops would be lost to pests.
C) The farmer may be held responsible for increasing chemical pollution.
D) The farmer's expenses for pest control would increase due to an increase in bee population.
Answer:
A) The financial costs for the farmer would be lowered since LESS crops would be lost to pests.
Explanation:
Planting of variety with a resistance strain to pest is one of the gene modification that occurs in plants, this has greatly help farmers improve on productivity, reducing the amount of money spent on controlling insect pest invasion on their farm.
Because the crop is resistant to pest no extra cost of purchasing chemicals to control pest on the farm and the number of damage to crop will be reduce in turn reducing the amount of plant lost to pest invasion this will lower the financial cost of the farmer and also an increase productivity.

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

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).

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?
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.
In pea plants purple flowers are dominant to white flowers.
If two white flowered plants are cross, what percentage of their
offspring will be white flowered?
Answer:
100%
Explanation:
This question involves a single gene coding for flower color in pea plants. The allele for purple flowers (P) are dominant to white flowers (p). This means that purple color will be expressed in a heterozygous state.
According to this question, If two white flowered plants are cross i.e. pp × pp, the following gametes will be produced by each of the parent: p and p. Using these gametes in a punnet square (see attached image), ALL (100%) of the offsprings will be white colored (pp).
Therefore, 100% of the offsprings will be white flowered.

1. Tina is a microbiology student using an HOL kit for her online course. She shares a small apartment with her two cats, and has a full time job across town. Suggest two potential locations in the apartment for Tina to store the lab materials and incubate cultures. Explain why these locations are appropriate choices for Tina.
Answer:
A cabinet and a small closet.
Explanation:
A cabinet and a small closet are the best locations to incubate cultures because these location are safe from the cats interaction with the microbial culture. A cabinet consist of a cupboard with shelves or drawers for storing things. Closet is a tall cupboard which is used for storage things so due to height the cats can't reach to these place so the culture is safe.

Base from your opinion, why we need to study the beginning of the universe? Give at least five reasons.
Answer:
To know the origin of life, to have an idea of our ancestors, to be aware of the immensity of the universe, for informational reasons and to respect nature.
Explanation:
Many scientists and psychologists affirm that it is very complex for the human mind to understand the cycle of life and the origin of the universe, due to its immensity.
This is how it is necessary to be in constant scientific updating so as not to transmit false information and unravel human myths that are generated by lack of understanding of life-death.
Is an ionic bond more like a polar covalent bond or a non-polar covalent bond? Explain
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.

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.
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.
A neurologist noticed that in one patient, damage to brain structure A resulted in a major
disruption in speech production, but left hearing ability intact. However, in another patient,
damage to structure B left major hearing impairment, but did not affect speech production.
This scenario is an example of...
Wernicke's aphasia.
a double dissociation.
Broca's aphasia.
a single dissociation.
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.

A study is being done to test the effects of temperature on the number of microbial colonies. Four different incubators are set up, each at a different temperature with one culture plate in each. Each plate has the same nutrient content, pH, and are inoculated with microorganism samples from the same source. At the end of the experiment, the number of colonies on each plate is counted. What is the independent variable
Answer:
The correct answer is - the different temperatures of incubators.
Explanation:
An independent variable is a variable in a study or research which is manipulated or changed to check or find the effect on the dependent variable. The independent variable is the only factor that changes in research while other factors remain constant that can affect the result in the study.
In this case or study, there is the only factor that is manipulated is the temperature of incubators is manipulated to see the effect of temperature on the number of microbial colonies. Thus, the different temperatures of incubators is the independent variable here.
