Answer:
c. causes cells to swell and burst, whereas apoptotic cells shrink and condense
Explanation:
These two mechanism are responsible for death of cells in multi cellular organisms.Apoptosis is naturally occurring process which is well organised and programmed.It is ensures the automatic death of old and worn out cells, needed for certain cellular developments. This is demonstrated by DNA fragmentation,cell shrinkage,and the break down of the nuclear walls.It can be initiated through two pathways of intrinsic and extrinsic,The latter leads to death from internal factors,while in the former is when external factor causes the death .
However,when cell death is influenced by external factors(toxins) in the cell environments,which lead to unpredictable or unregulated process leading to cell death ,the process is called Necrosis.it is demonstrated with the swelling and busting of the cell.and characterised with inflammation. It is an accidental death which causes injuries to the cells and tissues.
How does the wheat stem rust fungus harm its host plant?
Answer:
The stem rust fungus produces several different structures during its life cycle. The most obvious of these on wheat are the reddish-colored urediniospores that form on leaves, stems, and heads during the growing season. These spores are spread by wind and infect wheat or barley plants.

Explanation:
many endangered species are predators that belong to the higher trophic levels. Which is the process that primarily affects animals at the highest trophic levels?
Answer:
Top predators at the highest trophic levels eat lower-level predators and herbivores
Explanation:
A trophic level is defined as one group of organisms in the ecosystem occupying the same level in the food chain, which is composed of different levels (primary, secondary and higher levels). Top predators at the higher levels maintain the trophic balance by eating other species that eat on primary producers/consumers, thereby favoring the homeostasis of the ecosystem.
What is Ependymal cell?
Answer:
Explanation: Ependymal cell is a type of neuronal support cell the forms the epithelial lining of the brain ventricles in the brain and the central canal of the spinal cord ependymal cells similar to all other neuroglia, are derived from a layer of embryonic tissue known as neuroectoderm.
Ependymal cells are ciliated-epithelial glial cells. It develops from radial glia alongside the surface of the ventricles of the brain and spinal canal.
What is the function of Ependymal cells?The main role of Ependymal cells is formation of CSF.
The CSF refers to cerebrospinal fluid. It is done by movement of sodium ion, chlorine ion and bicarbonate ion from blood to ventricles of brain.
Inside ventricles of the brain, collection of ependymal cells and capillaries together i.e., the tela choroidea form choroid plexus, which produces the CSF.
Thus, Ependymal cells are involved in formation of CSF.

Which of the following not an enzyme
mediated process
1) G1
and G2
phases of meiosis
2) S-phase of mitosis
3) Pachytene of meiosis-I
4) None of the above
Answer:
4) None of the above
Explanation:
Enzymes are known for mediating biological or chemical processes.
Meiosis and mitosis both are part of a biological process called cell cycle or cell division.
The cell cycle is mediated by enzyme cyclins and cyclin-dependent kinases (CDK). cyclin-CDK in G1 phase helps to prepare the cell for S phase. cyclin-CDK also drives Pachytene of meiosis-I
During S-phase of mitosis, ubiquitin ligase helps in mitotic spindle assembly.
Hence, the correct answer is "4) None of the above"
Discuss Connell and Slatyer three mechanisms of succession. Start your answer with a definition and an example of what is succession, and describe how succession begins.
Answer:
Facilitation, tolerance and inhibition models
Explanation:
J. H. Connell and R. O. Slatyer stated three different ecological succession models that explain how species composition may change by the effects of disturbances in the ecosystem. These models are as follow:
1- Tolerance model: in this model, the new species don't affect the growth and success of existing species, thereby the process of succession is purely associated with life-history strategies.
2- Facilitation model: only 'ideal traits' found in colonizing species lead to the initial succession. These ideal traits include for example effective mechanism of dispersal, water storage tissues to survive in dry regions, long-term seed dormancy, etc.
3-Inhibition model: Species that appeared during early succession are capable of inhibiting growth of species appeared in later stages, as well as reduce colonizing species abundance.

List three protozoan infections of the circulatory system that are transmitted by arthropods. Include the disease name, specific organism (genus species), vector that is the intermediate between hosts, and disease progress in humans.
Answer:
List three protozoan infections of the circulatory system that are transmitted by arthropods:
Malaria
Toxoplasmosis
Chagas disease (American trypanosomiasis)
Explanation:
Malaria is a prozotoan infection, that can be produced by several protozoan, in the genus Plasmodium. This Plasmodium infect red blood cells and the vector that trasmites it is the Anopheles mosquitoe. In this disease, red blood cells can have severe damage in different organs because of the hemolysis.
Toxoplasmosis is a disease caused by the protozoan Toxoplasma gondii. The main vector of them are domestic cats. When cats are infected, T. gondii oocysts is found in their feces and it can spread to humans. This disease is generally asymptomatic, except when the patient has AIDS or in pregnancy, which can be very dangerous and fatal.
Chagas disease, or American trypanosomiasis is caused by protozoan Trypanosoma cruzi and is generally transmitted to people thanks to the feces of triatomine bugs. Some of the acute symptoms include fever, vomiting, headache, and in severe cases people can develop a chronic disease. In the worst cases it can produce flaccid cardiomegaly (enlargement of the heart) leading to heart failure and death.

A client reports extremely frequent urination, sometimes urinating 10 to 12 times each day.
What fluid balance disorder would be expected with these symptoms?
Answer:
Lack of Antidiuretic hormone.
Explanation:
Antidiuretic hormone is a type of hormone which is responsible for controlling urination. It is produced in hypothalamus which is a part of a brain. Antidiuretic hormone is responsible to tell the kidney how much water in the body should be conserve to avoid dehydration. If less antidiuretic hormone is produced by the body so more urine is produced. Frequent urination is also occurs due to Diabetes insipidus. This disease produce more urination in order to control the concentration of glucose in the blood.

If pattern of inheritance is complete dominance what would you expect when a red and yellow fish were crossed
In the question, it is not mentioned that which fish is dominant and recessive, so lets consider red fish is dominant and yellow fish is recessive.
Answer:
In complete dominance, the dominant trait completely masks the recessive trait and the offspring shows dominant characters only.
When a red and yellow fish were crossed, the pattern of inheritance is complete dominance which means the offspring would have dominant characters.
As we considered, red fish has dominant trait so the offspring produced will also have red color as yellow color (recessive) will be masked by dominant red color fish.

Examine the following diagrams. Columns I and II contain rock layers A, B, C, D, E, and F. Both columns were taken from the same dig site at different locations. Which two layers are of approximately the same age? (Note: The diagrams are attached).
Answer:
C and D
Explanation:
Layers C and D apparently contain the same fossilized organisms in the same substrate. Their appearance is very similar. By knowing that certain organisms used to live in a certain period of time, if we find two strata that show the same fossilized organisms, then we can estimate that these two strata are the same age. Fossilized organisms are used to estimate the age of a rocky stratum.
Life history can be illustrated through fossilized organisms trapped or converted into rocks. These fossils are known as index or guide fossils, of animal or vegetal nature, and they can apport information about the rocky stratum in which they are located or incrusted. These fossils are used to determine the age of the rocky sediments or the environmental conditions under which they were deposited.

You palpate a soft, slightly tender mass in the right scrotum of an adult male. You attempt to reduce the size of the mass, and there is no change in the mass size. Your next assessment maneuver is to:________
a. use two fingers to attempt to reduce the mass.
b. palpate the left scrotum simultaneously.
c. lift the right testicle and then compare pain level.
d. transilluminate the mass
Answer:
d. transilluminate the mass
Explanation:
Sometimes, painless hard or tender mass develop in the scrotum of men and can cause testicular tumors.
After detecting a scrotal mass, to reduce the size of the mass, the next assessment required is to transilluminate the mass in which testicles will be appear opaque on transillumination. Transillumination of mass will help to detect the orientation of mass which can be treated further.
Hence, the correct answer is d. transilluminate the mass
Production of maltose, by ___________________ condensation, dehydration, hydrolysis) of starch, in the presence of amylase, can be detected by colorimetric assay.
Answer:
Hydrolysis.
Explanation:
Maltose is produced by hydrolysis of starch, in the presence of amylase, can be detected by colorimetric assay. As per the assay of hydrolysis of starch we have concluded from the test of enzyme activity of amylase is that maltose being a reducing sugar which reacts and reduces the DNS (3,5-dinitrosalicylic acid) that is basically a pale yellow colored alkaline which results after some minutes into 3-amino,5-nitrosalicyclic acid which orange red colored alkaline after heating.

Answer:
Personalized genomic medicine
Explanation:
Personalized genomic medicine is a field that uses genomics data to develop personalized technologies and therapies for clinical care. All people share a sequence homology level higher than 99%; however a very small fraction of the genome (lesser than 1%) contains genetic polymorphisms among individuals, and this variation is associated with the likelihood of suffering diseases, either by increasing or by reducing disease susceptibility. Personalized genomic medicine first identifies genetic variations and then develops new strategies and personalized drugs to treat genetic disorders.

n your lab you are studying the genome of venomous rattlesnakes to find the gene which codes for their venom glands. You have two rattlesnakes, one rattlesnake has a mutation but can still produce venom. You compare his DNA to a normal rattlesnake. What type of mutation has occurred? Normal: AATCGCTACGCACGTCAG Mutated: TATCGCTACGCACGTCAG
Answer:
There are no options but the kind of mutation that occurred by carefully observing both sequences is:
POINT SUBSTITUTION MUTATION
Explanation:
Mutation is any change, whether small or big, in the nucleotide sequence of a gene (DNA). Mutation occurs from time to time in an organism either by a mistake during DNA replication or induced by a mutagen (mutation-causing substance). Mutation can be of different types depending on the effect on the mutant.
In this case of comparing the DNA sequence two rattle snakes, the sequences of the two snakes are:
Normal: AATCGCTACGCACGTCAG
Mutated: TATCGCTACGCACGTCAG
By carefully observing the two DNA sequences, one would realize that the only difference in the two sequences is the first nucleotide base. That is, in the normal sequence, th first base is Adenine (A) while in the mutated sequence, the first base is Thymine (T).
This type of mutation that involves only one nucleotide base is called POINT MUTATION. It can also be noticed that base "A" was changed "T". Hence, this is a type of SUBSTITUTION MUTATION because a single base was replaced by another in the sequence.
Angiosperms exhibit a great variety of forms, as well as means of obtaining nutrients. Angiosperms can be ___________. (Circle the correct answer.) g
Answer: Options are not given.
Here are the options.
A. Autotrophs
B. Saprophytic
C. Parasitic.
D. Both a and b.
E. All of the above.
The correct option is all of the above.
Explanation:
Angiosperms are flowers and seed producing plants and their seeds are enclosed in ovary.The angiosperms are vascular seed plants in which the ovule (egg) is fertilized and then develops
into a or become a seed in an enclosed hollow ovary. They are most diverse and largest group of animal kingdom.
Some angiosperms are autotrophs that uses carbondioxide, water and sunlight energy to produce their own food and releases oxygen.
Examples include maize, rice..
Some angiosperms are saprophytic which obtain energy from dead and decaying matter in the soil. They form a symbiotic relationship with fungi. Example is Neottia.
Some angiosperms are parasitic and they attach to their host through haustoria their by feeding on the host and causing harm on the host.
