C.It is a conditioned response that occurs only to prevent injury!
D. It is a voluntary response that is initiated only after the impulse has been caried to the relevant area of the brain
Answer:
B. It is a reflex response that causes various muscles to contract in order to move away from the object.

Explain how the TATA box and transcription factors work together to ensure that RNA polymerase is transcribing the correct region of the DNA molecule.
Answer:
How does RNA polymerase know where to start transcribing a gene?
To begin transcribing a gene, RNA polymerase binds to the DNA of the gene at a region called the promoter. Basically, the promoter tells the polymerase where to "sit down" on the DNA and begin transcribing. ... A promoter contains DNA sequences that let RNA polymerase or its helper proteins attach to the DNA.
TATA box and transcription factors work together to ensure that RNA polymerase is transcribing the correct region of the DNA molecule.
What is transcription?Transcription, the synthesis of RNA from DNA. Genetic information flows from DNA into protein, the substance that gives an organism its form.
The TATA box is able to define the direction of transcription and also indicates the DNA strand to be read. Proteins called transcription factors can bind to the TATA box and recruit an enzyme called RNA polymerase, which synthesizes RNA from DNA.. The TATA box marks a point just before the point at which transcription begins, so that RNA polymerease transcribe the correct region of DNA molecule.

In an early experiment, it was found that a mouse in a sealed glass jar soon died, but if a plant was included in the jar, the mouse lived much longer. Explain theses results.
Answer:
The correct answer is - mouse produces carbon dioxide which is used by the plants for photosynthesis that in turn produces oxygen that is used for cellular respiration.
Explanation:
A mouse can not live in a sealed container or jar for a long time whereas with a plant in a closed and sealed jar mouse can live longer. This is due to the fact that in absence of the plant there is no oxygen for the mouse to get perform cellular respiration.
in a jar with a plant, the mouse lives longer because the plant still produces oxygen by the process of photosynthesis which is used by the mouse for cellular respiration and produces carbon dioxide that is taken by the plant.

How has the Gila Monster adapted to the breeding patterns of its prey the Gambel quail and desert cottontail rabbits?
The Gila Monster has therefore adapted to consume its entire yearly energy supply in a few meals in the spring. It stores much of its energy as fat in its tail so it can survive the rest of the year.
Answer:
As the Gila monster consumes the eggs or young of the desert cottontail and Gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. However, for this, the Gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.

The peppered moth provides a well-known example of natural selection. The light-colored form of the moth was predominant in England before the Industrial Revolution. In the mid-nineteenth century, a dark-colored form appeared. The difference is produced by a dominant allele of one gene. By about 1900, approximately 90% of the moths around industrial areas were dark colored, whereas light-colored moths were still abundant elsewhere. Apparently, birds could really find the light morhs against the soot-darkened background in industrial areas and, therefore, were eating more light moths. Recently, use of cleaner fuels has greatly reduced soot in the landscape, and the dark-colored moths have been disappearing.
1.What forces are causing evolutionary change in these populations?
2. Should the two forma be considered separate species?
3. How would you determine if these are separate species?
4. Give a prediction for what future generations of moths will look like and explain why.
Answer:
a) Natural selection
b) Different
c) Different genotypes
d) Evolution of dark colored moth species from the light colored moth species
Explanation:
a) The pressure of selection due to the changing color of bark of tree because of air pollution caused by industries leads to natural selection in a way that dark colored moth are emerging
b) Yes the two forms of moths are two different species.
c) The genotype of the two species is different
d) All the moths will be of dark color in order to save themselves from predation. This will lead to evolution of dark colored moth species from the light colored moth species and hence will lead to extinction of light colored moth

1.1 Cell division is found to occur in:
A growth
B reproduction
С
cancer
D all options.
Answer:
Cell division is found to occur in both groth and reproduction.The answer is D
Answer:
D all options.
Explanation:
Cancer
Cancer is unchecked cell growth. Mutations in genes can cause cancer by accelerating cell division rates or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death.
Reproduction
Cell division usually occurs as part of a larger cell cycle. Both of these cell division cycles are used in the process of sexual reproduction at some point in their life cycle.
Growth
In unicellular organisms, cell division is the means of reproduction; in multicellular organisms, it is the means of tissue growth and maintenance. Most tissues of the body grow by increasing their cell number, but this growth is highly regulated to maintain a balance between different tissues

how are adaptation and variation similar?
Answer:
Adaptations are physical or behavioral traits that make an organism better suited to its environment. Heritable variation comes from random mutations. Random mutations are the initial cause of new heritable traits. For example, a rabbit can't choose to have a different fur color.

The Competitive Exclusion Principle states that: Group of answer choices a. When two species occur together, competition is always prevented by some behavioral adjustment. b. Two species that use a limited resource in the same way cannot coexist indefinitely. c. Two species that use the same community can use limited resources in different ways. d. When two species each compete for the same resource in the same location, competition will always evolve into commensalism. e. None of the choices are correct.
Answer:
b. Two species that use a limited resource in the same way cannot coexist indefinitely
Explanation:
The competitive exclusion principle establishes that two or more species that share the same niche requirements, in the same habitat, and are in biological competition for the same resources, won´t be able to coexist indefinitely in the same space if the other ecological factors are constant. This is because species with identical niches have the same necessities, which means that they will compete for the same resources. If these species have the same requirements, they can not coexist. When the superior competitor occupies the inferior competitor´s fundamental niche, the first species has advantages over the second species and monopolizes all the resources. From that moment, the inferior species is displaced and must adapt to use other resources changing its behavior, or must migrate to another area where it can get access to its needs or get extinct.
When two competing species coexist, this is because of niche partitioning or niche differentiation. One of the species uses a different resource, occupies another area, or uses the resources at different times during the day. If there is not any differentiation between them, the dominant species displaces the weak species.
Niche specialization might produce genotypic separation. Subpopulations of a species diverge into new species.
So, competitive exclusion refers to the exclusion of the inferior competitor by the superior competitor when there is not habitat differentiation, and both species can not share the same niche.
Answer:
B. Two species that use a limited resource in the same way cannot coexist indefinitely.
Explanation:
The Competitive Exclusion Principle states that: Two species that use a limited resource in the same way cannot coexist indefinitely.
