Which part of a mushroom would be eaten?
Thallus
Sporangium
Mycelium
Septum
Hyphae
Answer:
Ascomycetes have zygotes
Mycelium
Explanation:
Ascomycetes have zygotes which is the main distinction between Ascomycetes and Basidiomycetes. Mycelium is a part of mushroom that is edible and can be eaten. Mycelium is the vegetative part of a fungus that consist of a mass of branching, thread-like hyphae. Hypha is a long, branching, filamentous body of mushroom as well as oomycete and actinobacteria. Hyphae are the primary mode of vegetative growth of fungi which is generally known as mycelium so mycelium is the edible part of mushroom.

Which of the following statements is false? Choose one: A. Some Bcl2 family members promote apoptosis, whereas others inhibit apoptosis. B. Bax and Bak are death-promoting members of the Bcl2 family that induce the release of cytochrome c from mitochondria into the cytosol. C. Some death-inhibiting members of the Bcl2 family inhibit apoptosis by blocking cytochrome c release from mitochondria. D. The death-promoting members of the Bcl2 family include Bcl2 itself.
Answer: The statement that is FALSE is D (The death-promoting members of the Bcl2 family include Bcl2 itself.)
Explanation:
Apoptosis is a process found in multicellular organisms whereby cells follows a order of events which eventually leads to their death without releasing harmful substances into the surrounding area of the cells. Through this process, old cells, unnecessary cells, and unhealthy cells are eliminated from the body.
The process of apoptosis can be regulated by cell regulator proteins such as Bcl-2 family.
Bcl-2 stands for B-cell lymphoma 2 which are encoded in human cells by BCL2 gene. The Bcl-2 family are capable of regulating apoptosis by either inducing it or inhibiting it.
Bcl-2 and Bcl-XL, PREVENT apoptosis by preventing the release of mitochondrial apoptogenic factors such as cytochrome c and AIF (apoptosis-inducing factor) into the cytoplasm
Part of the Bcl-2 family is the Bax and Bak and they are the core regulators of the intrinsic pathway of apoptosis. They PROMOTE apoptosis by inducing the release of cytochrome c from mitochondria into the cytosol. Therefore, the death-promoting members of the Bcl2 family does not include Bcl2 itself.
Explain why the lack of surfactant would result in respiratory distress. Furthermore, what type of acid-base disorder might she develop and how would her body compensate. Be detailed in your explanation and support your answer with facts from your textbook, research, and articles from scholarly journals.
Answer:
Due to lack of expansion of lungs.
Explanation:
The lack of surfactant compound would result in respiratory distress because Surfactant enables the lungs to expand more easily which allows easiness in respiration. Without surfactant, the air sacs in the lungs will collapse very easily. This collapse leads to decreased amounts of air or oxygen in the lungs which makes it very difficult for the people or infant to breathe.

A forest was cleared and turned into a field of organic soybean plants. Which of the following most likely occurred?
A. The variety of plants and animals both increased
B. The number of insects increased
C. The number of insects decreased
D. The number of plant species increased
When a forest is cleared, biodiversity decreases. The correct answer is option C: The number of insects decreased
Biodiversity refers to different species of plants and animals in a habitat. We will all agree that the biodiversity in a forest ecosystem is much higher than the biodiversity in a field of organic soybean plants.
There are less species of organisms in the field of organic soybean plants.
Therefore, the variety of plants and animals both decrease.

The following types of tissue all are part of the category named muscle tissue:
Skeletal muscle
Smooth muscle
Cardiac muscle
3
Visceral muscle
A. B. and Care all correct.
Answer:
A, B and C are all correct.
Explanation:
There are three main muscle types:
Muscle skeleton — the specialized tissue that connects to the bones and enables movement. The musculoskeletal system is called skeleton muscles and bones together (also known as the locomotor system). Generally speaking, the biceps and triceps of the front or the back of the upper arm are arranged into opposing pairs. Skeletal muscles are controlled by humans, and so are also called voluntary muscles. Another term is streaked muscles, as the tissue looks streaked on a microscope. smooth muscle -located throughout several internal tissues such as the digestive tract, the uterus, and blood vessels such as the artery. The smooth muscle in layered sheets is placed along the construction length in waves. Another typical word is an involuntary muscle, because, without our knowledge, the motion of the smooth muscle takes place.The cardiac muscle - the heart muscle. Without our conscious awareness the heart contracts and relaxes.Mr. L was walking through the woods wearing shorts and sandals. He noticed a small tick on his ankle the same evening, and several weeks later he developed flu-like symptoms. A sample of his blood revealed the presence of long, wavelike cells that were twisting and waving. Based on the microscopic findings, which type of microorganism is responsible for Mr. L's symptoms
Answer:
Protozoa
Explanation:
The long, wavelike cells seen under the microscope would most likely be protozoa and the microorganism responsible for Mr. L's symptoms.
Tick as a vector is capable of causing diseases such as lyme disease, anaplasmosis, babesiosis, Powassan virus disease, tularemia, and a host of other diseases. Among all the diseases, babesiosis is particularly caused by a protozoan known as Babesia microti and it elicits malaria-like symptoms in individuals. Most of the other diseases are caused by bacteria pathogens while a few are caused by virus.
Apart from the above, the morphological characterization of the microorganism responsible for Mr. L's disease is typical for protozoans. Many of them are long and flagellated with a wave-like motion as a movement.
Hence, the case of Mr. L would be that of protozoa.

A geneticist finds that a strain of bacteria to produces a non-functional sigma factor. Which among the following steps in transcription would most likely be first affected?
A.Assembly of RNAP onto the DNA strand
B.Identification and binding of RNAP on to the promoter sequence
C.Conversion of open initiation complex to closed initiation complex
D.Synthesis of RNA after the formation of open initiation complex
Answer:
The correct answer is - B. Identification and binding of RNAP onto the promoter sequence.
Explanation:
Bacterial RNA polymerases have subunits known as Sigma factors responsible for the identification and specificity of promoter binding of RNAP and regulate the efficiency of RNA synthesis during transcription is initiated.
These bacteria producing the nonfunctional subunits of RNA polymerase or sigma factor will be unable to identify and tightly bind to promoter elements that are RNAP.
In an experiment to determine the acceleration due to gravity, one student holds a pencil at arm’s length and drops it. Another student starts a timer when the first student lets go and stops the timer when the pencil hits the ground. They repeat this several times and take an average. Is this a valid experiment, why or why not?
Answer:
The correct answer is - No, it is not valid because the short distance means there will be a lot of error due to the student's reaction time.
Explanation:
In this experiment to determine the acceleration due to gravity, there may be errors because of the student’s reaction time. The reaction can be late or early than prior reactions.
The other error can be caused by the distance was only at arm’s length throughout the experiment, which means that there was no independent variable that is the difference or change in the distance. This also makes the experiment invalid.
The locus B on the X chromosome of a malaria-carrying mosquito shows a 49% recombination rate with respect to the locus M. Since a recombination rate of 50% is essentially indistinguishable from independent assortment, you might be tempted to look for a locus that falls between B and M. Before you decide to do all that work, you run a chi square test to determine the P value of your experiment.
Required:
What range of P values would tell you that you should accept the conclusion that locus B and locus M are, indeed, 49mu apart and that another locus is not necessary?
Answer:
The correct answer is - P = 0.45
Explanation:
The Chi-square test is a test that determines the assorted genes independently. Here p-values used to make conclusions in significance testing.
If the p value is less than the significance level we expect or choose, then this null hypothesis is rejected in favor of the alternative hypothesis. It p value is greater than or equal to the significance level, then we fail to reject the null hypothesis.
So in this case, as the recombination rate is 49% so the p value which satisfies the conclusion will be around 0.45 and values near to it.

Suppose that you close a window because you notice that rain is falling. Your action in closing the window is a(n)
A. involuntary reaction.
B. depressant.
C. stimulus.
D. response.
Answer:
D. Response
Explanation:
Basically, You Are Coordinating What Is Happening Which Triggers The Brain For A Response.
Answer:
D.
Explanation:
You are responding to the rain by closing the window.
- it is not an involuntary action because that is something that doesn't require thinking such as breathing and blinking.
- it is not a depressant because that is something that reduces functional activity - so affects the body.
- it is not a stimulus because a stimulus is a change or signal in the environment that can make an organism react. So, in this case the rain would be the stimulus.

The development of DNA technology is bringing profound changes to science, agriculture and healthcare. Provide one example of a DNA technology and provide at least one advantage and one example of a concern or problem associated with its use.
Answer:
The CRISPR-Cas9 genome editing system can be used to edit genes and correct mutations associated with inherited diseases. However, this technology also has the potential to edit genes in germline cells in order to irreversibly modify the human species and the natural evolution of life
Explanation:
The CRISPR-Cas9 (Clustered regularly interspaced short palindromic repeats and CRISPR-associated protein 9) system is a natural prokaryotic defense system used by bacteria to defend against invading DNA. In the laboratory, the CRISPR-Cas9 system has been repurposed to create a versatile genome-editing tool that allows us to modify the genome of mammalian cells in a targeted fashion. The CRISPR-Cas9 is a simple gene-editing tool that consists of a single guide RNA (sgRNA) that guides the Cas9 enzyme to the exact genomic location where Cas9 needs to make a cut, which is then repaired by different DNA repair mechanisms. During DNA repair, nucleotides can be replaced and/or deleted, thereby producing desired genomic modifications. The CRISPR-Cas9 has an enormous potential to repair mutations in genes associated with inherited genetic disorders and cancer (i.e., oncogenes might be reversed in vivo by using this technology). However, the CRISPR-Cas9 genome editing system is also a subject of concern due to its dual use. For example, this technology can be used to modify the genome of germline cells by inducing mutations that can be passed across generations, thereby irreversibly modifying human DNA and altering the normal course of evolution.
