What is the result of a mutation during meiosis
Answers
Answer:
There's a change in the DNA sequence
Explanation:
If a mutation occurs in cells that will make gametes by meiosis or during meiosis itself, it can be passed on to offspring and contribute to genetic variability of the population. Mutations are the sole source of genetic variability that can occur in asexual reproduction. But the effects of mutations can vary widely, from being beneficial, to having no effect, to having lethal consequences, and every possibility in between.
Spatial perception and the recognition of familiar objects require activity in which of the following cortical regions?
a. Auditory association areas
b. Primary olfactory cortex
c. Visual association areas
d. Orbitofrontal cortex
Answers
Answer:
c. Visual association areas
Explanation:
The visual association areas are part of the cerebral cortex and are responsible for allowing human beings to have special perception, movement perception, visual perception processing and recognition of familiar objects. These areas are extremely important for the maintenance of human activities, and the deterioration or disturbance of these causes serious problems, difficult to be resolved.

How do somatic and Inherited mutations differ?
O A. Somatic mutations exist in all cells in the body and Inherited mutations only exist In the cell type that mutated.
O B. Inherlted mutations exist in all cells in the body and somatic mutations only exist In the cell type that mutated.
O C. Somatic mutations only affect males and inherited mutations affect any gender.
O D. Inherited mutations only affect males and somatic mutations affect any gender.
Answers
Inherited mutations are gene mutations that exist in almost every cell in the body throughout an individual’s life. Inherited mutations are inherited from a parent and can also be transmitted. They are also called germline mutations because they exist in the parent’s egg or sperm cells (gametes).
Somatic mutations are gene mutations that exist in only certain cell types that are mutated, not in every cell in the body and it take place at some time during an individual’s life. Somatic mutations are not inherited and cannot be passed. They are caused due to environmental factors (such as cigarette smoke or ultraviolet (UV) radiation) or due to error during DNA replication.

You are a research biologist working at the U.S. research station in Antarctica. You discover a new single-celled organism that is able to survive in the frigid conditions. During your research you observe that the organism has a nucleus. Which domain would this new organism be classified into
Answers
Answer: Eukarya.
Explanation:
The cell is the functional and morphological unit of all living beings. Organisms can be classified as follows: if they are composed of a single cell, they are called unicellular (such as protozoa or bacteria which are microscopic organisms), or mutlicellular if they have more cells.
The three-domain system is a biological classification into three groups:
Archaea Bacteria Eukarya.It is based on the differences found in the sequence of the ribosomal RNA of the minor subunit to conclude that these groups developed separately from a common progenitor.
Archaea are a group of unicellular prokaryotic microorganisms that have no nucleus or any internal membranous organelles. However they are different from bacteria, so that they form their own domain.
Bacteria are prokaryotic microorganisms that do not have a defined nucleus nor do they generally have internal membranous organelles.
Although archaea and bacteria are morphologically very similar, archaea are closer to eukaryotes in some genes and pathways of transcription and translation. Thanks to studies of genetic material, now we knot that the evolution of archaea and bacteria had been independent, so archaea could no longer be considered as a group of bacteria. However, the Archaea and Bacteria domains include prokaryotic organisms, i.e. those whose cells do not have a differentiated cell nucleus.
The Eukarya domain includes the best known and most complex forms of life (protists, animals, plants and fungi). It includes organisms formed by cells with a true nucleus. These organisms consist of one or more eukaryotic cells, ranging from unicellular to multicellular organisms in which the different cells are specialized for different tasks and which, in general, cannot survive in isolation.
So, if the observed organism possesses a nucleus, then it is a eukaryote.
Melanie has had a recent cold with symptoms of runny nose, sneezing, coughing, congestion, and malaise. Today, she is concerned that she has a sharp pain in her chest. She goes to see her health care provider, and is diagnosed with costochondritis, an inflammation in the cartilage between the ribs. From your reading related to cellular injury and adaptations as well as inflammation, answer the following questions:
a. What anatomic problem most likely leads to costochondritis?
b. What is the injury in costochondritis?
c. What would the acute inflammatory response look like?
Answers
Answer:
a. Viral infections may lead to inflammation between the ribs (i.e., costochondritis)
b. Viral infection
c. Viral infection may lead to the influx of chemical mediators (cytokines), increased blood flow, and movement of plasma and white blood cells (leukocytes) from the blood into the injured site
Explanation:
Costochondritis is a painful condition caused by the inflammation of the cartilage that joins the ribs to the breastbone (this joint is known as the “costochondral joint”). Costochondritis is caused by inflammation of the costochondral joint, which may be triggered by multiple causes including, among others, viral/bacterial/fungal infections, exercise or strenuous activity, chest trauma, osteoarthritis, presence of tumors, etc. Acute inflammation is the immediate immune response of the body to harmful stimuli (e.g., viral infections), which is characterized by the increased movement of white blood cells (such as neutrophils and macrophages) that rapidly travel from the blood into the injured area. This plasma contains chemical mediators like pro-inflammatory cytokines which are secreted from immune cells (e.g., Th1 cells, CD4+ cells, macrophages) in order to promote inflammation.

2074/What is mutation? Explain different types of mutation involving changes in
chromosome number and chromosome structure?
Answers
Answer:
Mutation is the changing of the structure of genes resulting in a varied form that may be transmitted to subsequent generations, caused by the alteration of single base units in DNA or the deletion, insertion, or rearrangement of larger sections of genes or chromosomes.
A silent mutation is a mutation where the codon still corresponds to the same amino acid. The sequence of amino acids is not changed so the protein that gets made is the same as the wild type, or normal protein.
A missense mutation changes the codon so that it codes for a different amino acid.
Finally, a nonsense mutation causes protein creation to stop early, which makes a non-functioning protein.
Substitution means that one base is exchanged for another. This is kinda like having a substitute teacher. The sub isn't your normal teacher, but they are still a teacher. A protein that is made with a substitution might still function normally, or it could be nonfunctional.
Deletion is kinda self-explanatory. It happens when a base is deleted or, in other words, is just missing.
Finally, insertion means an extra nucleotide is added.

b. Acetylcholine diffuses across the synaptic cleft before binding to its receptor, which is located on the _____
c. When the membrane potential reaches ________an action potential spreads across the sarcolemma due to the opening of ___________
d. In response to acetylcholine binding, ________ move into the muscle fiber causing the membrane potential to rise.
Answers
Answer:
a). Voltage-gated Ca2+ channels
b). the motor end plate
c). Threshold, voltage-gated Na channels
d). sodium ions
Explanation:
a). The voltage-gated [tex]Ca^{2+}[/tex] channels are the key transducers of the membrane potential that changes into a intracellular [tex]Ca^{2+}[/tex] transients which initiates the physiological events. When the action potential makes a contact with axon terminal, the voltage-gated [tex]Ca^{2+}[/tex] channels opens.
b). The acetylcholine is the main neurotransmitter of the parasympathetic nervous system. It helps in blood vessels dilation, muscle contraction, and perform many more functions.
It diffuses with the synaptic cleft that is located on the motor end plate of the nervous system.
c). The membrane potential is also known as the membrane voltage or the transmembrane potential. When it recaches the threshold, the voltage-gated Na channels opens to spread the action potential across sarcolemma.
d). The sodium ions in case of acetylcholine binding moves to the muscle fiber due to which the membrane potential rises.

Factors determine energy a human being requires in a day
Answers
Energy balance is achieved when input (i.e. dietary energy intake) is equal to output (i.e. total energy expenditure), plus the energy cost of growth in childhood and pregnancy, or the energy cost to produce milk during lactation. When energy balance is maintained over a prolonged period, an individual is considered to be in a steady state. This can include short periods during which the day-to-day balance between intake and expenditure does not occur. An optimal steady state is achieved when energy intake compensates for total energy expenditure and allows for adequate growth in children, and pregnancy and lactation in women, without imposing metabolic, physiological or behavioural restrictions that limit the full expression of a person’s biological, social and economic potential.
Within certain limits, humans can adapt to transient or enduring changes in energy intake through possible physiological and behavioural responses related to energy expenditure and/or changes in growth. Energy balance is maintained, and a new steady state is then achieved. However, adjustments to low or high energy intakes may sometimes entail biological and behavioural penalties, such as reduced growth velocity, loss of lean body mass, excessive accumulation of body fat, increased risk of disease, forced rest periods, and physical or social limitations in performing certain activities and tasks. Some of these adjustments are important and may even increase the chances of survival in times of food scarcity.
