Answer:
Processing and storing food.
Explanation:
The coelom is the hollow structure formed in the organisms filled with the coelom fluid. The coelom is formed during embryogenesis which may be lined by the mesodermal layer or not.
The formation of coelom serves many functions in different organisms like it allows the internal movement of the organs in the body, allows the independent movement of the digestive tract, the fluid present in the cavity acts as a hydrostatic skeleton in the lower organism and cushions the internal organs.
The function that is not performed by the coelom is that it is not involved in the processing and storing food in organisms.
Thus, Processing and storing food is correct.
Phalloidin is a peptide that can be conjugated to fluorescent dyes, such as fluorescein, and used to label actin in cells. Phalloidin-fluorescein was added to dividing, ciliated cells in culture. Where will the fluorescence be localized in the cells when looking at the treated cultures using fluorescence microscopy?
a. at the inner surface of the inner nuclear membrane
b. at the inner surface of the plasma membrane
c. microtubule-organizing centers (MTOC) cilia
d. more than one of the above.
Answer:
b. at the inner surface of the plasma membraneExplanation:
Phalloidin is a type of toxic substance that is found in dead cap mushrooms. It has a bicyclic structure of heptapeptide. It has a great ability to bind with the filamentous actin selectively and tightly. So it is used in the fluorescent microscopic study to detect or identify the structure or position of the F- actin. Due to phalloidin small structure, generally it is used in the labeling of cellular protein during the fluorescent microscopy to increases high resolutions. Since most of the actin is connected with the inner surface of the plasma membrane so the cells that are treated with phalloidin, has fluorescence at the inner surface of the plasma membrane.The reactants of cellular respiration are

Which of the following observations best supports the cell theory? Cells from animals only create other animal cells. Cells come in a variety of shapes and sizes. Cells have different names for different structures. Cells can live a very short time.
What type of information is encoded within genes
a gene is a sequence of nucleotides in DNA or RNA that encodes the synthesis of a gene product, either RNA or protein.
Final answer:
Genes encode information in the form of sequences of nitrogenous bases in DNA, grouped into codons in mRNA, which specify amino acids for proteins. The genome contains all hereditary information, directing cells to produce specific proteins essential for life. This genetic information is passed down through generations.
Explanation:
The information encoded within genes is essentially the blueprints for building an organism and is found in the organism's DNA. This information is stored as a sequence of nitrogenous bases represented by the letters A (adenine), C (cytosine), G (guanine), and T (thymine) in DNA, which translate to A, C, G, U (uracil) in mRNA. These sequences are grouped into sets of three called codons, and each codon specifies a particular amino acid, the building block of proteins, or signals the start or end of protein synthesis.
An organism's genome comprises all the hereditary information, which includes both the genes and non-coding sequences of DNA. Just like instructions in a manual lead to the construction of a model airplane or the knitting of a sweater, the DNA 'instructions' guide the cell in the production of proteins. The resultant proteins are critical for the cell's structure and function, with various proteins like interleukin-2 and alpha-2u-globulin serving as examples of the diversity of structures that are directed by genetic information.
Each gene on a chromosome can be seen as a section of DNA that provides the code not only for the corresponding RNA but also for the proteins required for all life processes. Thus, through the replication of DNA, genetic information is faithfully transmitted from one generation to the next, ensuring the continuity of biological traits.

The relationship between a carnivore and an herbivore can be stated as
The relationship between a carnivore and an herbivore is a predator-prey relationship that plays a crucial role in maintaining ecosystem balance.
Explanation:The relationship between a carnivore and an herbivore can be stated as a predator-prey relationship. Carnivores are animals that consume other animals, while herbivores are animals that feed primarily on plants. The carnivore hunts and captures the herbivore for food, and this interaction is essential for maintaining ecosystem balance.
For example, in an African savanna, lions are carnivores that prey on herbivores like zebras and antelopes. The lions rely on the herbivores for food, and the herbivores play a crucial role in keeping the vegetation in check.
The relationship between carnivores and herbivores is an integral part of the food chain and helps regulate populations and energy flow within an ecosystem.

The relationship between a carnivore and an herbivore is a predation relationship where the carnivore is the predator and the herbivore is the prey. Herbivory is a specific type of predation focused on the consumption of plants by animals, which can also help in plant reproduction through seed distribution.
The relationship between a carnivore and an herbivore is an example of predation, where the carnivore acts as the predator that hunts and consumes the herbivore, which is the prey. This interaction is a fundamental ecological process that accounts for most energy transfers in food chains and webs. Carnivores like lionesses consume animals, while herbivores such as zebras eat plant species. Despite both being consumers, the principal difference is that carnivores feed on other animals, whereas herbivores feed on plants.
While herbivory is also a form of predation, it specifically describes the consumption of plants by animals. Most plants cannot escape or camouflage themselves from predators, so they have evolved various defense mechanisms against herbivory. Additionally, some plants utilize herbivory to their advantage by using animals as a method for seed distribution and plant reproduction.

Imagine a scenario where a disease has infected many species of grass in the savanna. How would this situation affect the animals that live there?
Answer:
The effect that a situation like this:
Imagine a scenario where a disease has infected many species of grass in the savanna.
Would have in is A disbalance in the ecosystem because the infected plants would die and they won't be able to feed the animals that eat them and they would have to migrate to look for plants to eat. That would also lead to predators that eat the animals that feed on plants to follow them and both types of animals would be reduced in the trip.
Explanation:
To understand this answer we need to analyze the full context. First of all the plants are used as food by the herbivores, therefore they would see themselves in the need to look for healthy plants that could be used as food. Predators would follow them and this trip will reduce the number of both because they would require energy and food to keep traveling. The herbivores would take the worse part because they are bigger in number and their food would scarce, while they would be used as easy food for the carnivores.
Answer:
If a disease infected most of the grass in the savanna, the animals that thrive on the grass wouldn’t have enough food. Some of the smaller organisms use the grass for shelter and protection. Without these grasses, many organisms would either die or move to a better location for food. Then meat-eating animals would also have less food to eat.

Do you think Peacocks would be in Hardy-Weinberg Equilibrium? Why or why not?
Peacocks would not be in Hardy-Weinberg Equilibrium
Explanation:
This can be justified by the mating patterns of the female peacocks. They do not choose their mates randomly but look out specifically for bright attractive plumage in their male partners and then select them.
Hardy-Weinberg's Equilibrium of evolution mechanism was based on facts like random mating, no natural selection, mutation, absence of gene flow, and infinite population size.
They stated that organisms mate randomly with each other without any specific or a particular preference in the phenotypes of their opposite mates
How do cigarettes and radiation cause cancer? View Available Hint(s) How do cigarettes and radiation cause cancer? by destroying healthy cells by repressing the cell cycle by toxic chemicals (in smoke) or radiation that can damage the DNA in cells by destroying DNA by activating DNA mismatch-repair enzymes
Answer: B. by toxic chemicals (in smoke) or radiation that can damage the DNA in cells.
Explanation:
The carcinogens presents in cigerates covalently bind to DNA and form DNA adducts which results into miscoding (e.g., insertion of the wrong base) during replication of DNA and this genetic mutation causes uncontrolled cellular growth which causes cancer.
Ionising radiation including X-rays, radioactive particles, and gamma rays,can cause cancer by damaging DNA. high-energy radiation damages DNA and cause genetic mutation same as cigerates and causes cancer.
Both toxic chemicals (in smoke) or radiation damages DNA inthe cells which leads to cancer.
Hence, the correct option is B.

During which phase of mitosis do sister chromatids separate?
Answer:
I think Anaphase II
Explanation:
Hope this help
Sister chromatids separate during the anaphase phase of mitosis. This critical phase ensures that each new cell has a precise copy of the genetic material contained in the original cell.
Explanation:Sister chromatids separate during the anaphase phase of mitosis. It's a critical juncture in cell division when replicating chromosomes split into two new identical sets. The chromatids, initially paired together at the beginning of mitosis, comply with the pull of the spindle fibers, moving each sister chromatid to opposite ends of the cell. The separation of sister chromatids ensures that each new cell formed during division will have a precise copy of the genetic material contained in the original cell.

Answer:
The signs and symptoms of HELLP syndrome include high blood pressure, protein in the urine, headache , nausea , abdominal pain, backache , changes in vision, anemia and tiredness , swelling, etc.
Explanation:
Preeclampsia is a pregnancy complication occurring in pregnant women that usually happens late in pregnancy and is characterized by high blood pressure, protein in urine, edema or swelling in hands, legs, feet, face, etc.
HELLP syndrome (H - hemolysis, EL - elevated liver enzymes, LP - low platelet count) is another disorder that arises usually in association with preeclampsia. It usually occurs during the last trimester of pregnancy or postpartum and is characterized by hemolysis due to the rupturing of red blood cells, elevated liver enzymes due to leakage of high amounts of enzymes from injured liver cells, and a low platelet count. Hemolysis or breakdown of red blood cells results in low red blood cell levels and eventually leads to anemia. Low platelet count prevents clotting and can cause excessive bleeding.
The first signs of this syndrome seem like preeclampsia which includes high blood pressure and protein in the urine. Later, other symptoms such as
headache nausea swelling due to fluid retention anemia and tiredness indigestion with pain after eating abdominal pain (upper right side pain from liver distention) backache shoulder pain pain when breathing deeply blurry vision or other visual issues excessive and sudden weight gain bleeding seizuresComplications may also include rupture of the liver capsule, placental abruption, disseminated intravascular coagulation, kidney failure, etc.

The m phase checkpoint ensures that all chromosomes are attached to the mitotic spindle. If this does not happen, then
Answer:
The cells would most likely get arrested in the metaphase stage.
Explanation:
Certain points found in the cell cycle of eukaryotes, at which the advancement of the cell to the next stage of the cycle can be prevented until and unless all the conditions become favorable are known as the check points. One of these checkpoints is the M checkpoint, which is found close to the termination of the mitosis metaphase stage.
It is also known as the spindle checkpoint as it determines the accurate attachment of the sister chromatids with the spindle microtubules. At the time of the anaphase stage, the distinction of the sister chromatids is an irreversible step, thus, unless and until each sister chromatids pair are attached strongly with the spindle fibers originating from the reverse poles of the cell, the cycle will not progress further.
Therefore, if all the chromosomes are not attached to the mitotic spindle the M checkpoint will not allow the cell to go the next stage and will arrest the cell in the metaphase stage.
The M phase checkpoint ensures that all chromosomes are attached to the mitotic spindle. If this does not happen, then the cell will be arrested in metaphase.
The cell cycle can be divided into interphase and a mitotic 'M' phase in which the cell divides. The M phase can in turn be divided into prophase, metaphase, anaphase and telophase.The M checkpoint ensures the correct attachment of chromosomes to the mitotic spindle. During metaphase, the chromosomes align at the equator (middle) of the cell.In conclusion, the M phase checkpoint ensures that all chromosomes are attached to the mitotic spindle. If this does not happen, then the cell will be arrested in metaphase.

The following diagram shows an oceanic food web. At what trophic level do the killer whales primarily feed?
Killer whales, based on a general oceanic food web, primarily feed at the fourth trophic level. This is because they feed on secondary consumers like seals, positioning them as tertiary consumers or apex predators.
Explanation:In a food web, the trophic level refers to the position an organism occupies based on its feeding habits. Primary producers make up the first trophic level, followed by herbivores or primary consumers at the second trophic level, and carnivores or secondary consumers make up the third trophic level. If Killer Whales feed on organisms like seals, which are secondary consumers, then Killer Whales would be positioned at the fourth trophic level—also known as tertiary consumers or apex predators.
This is based on a generalized oceanic food web and may not represent every environment. Additionally, depending on the specific diet of the Killer Whale in different environments, it could occupy more than one trophic level. For example, if a Killer Whale also eats fish, it could be a secondary as well as a tertiary consumer.

You have arrived on the scene of an incident involving an explosion. People in the immediate vicinity are all experiencing runny noses and difficulty breathing. Some are having convulsions. You suspect a terrorist incident involving a:
A. biological agent
B. blister agent
C. nerve agent
D. blood agent
Answer:
Nerve agent
Explanation:
A nerve agent is a chemical in which on exposure to humans affects the functioning of the nervous system. These chemicals are known to disrupt the process by which messages are transferred to the organs from the nerve. This disruption occurs by blocking the activity of acetylcholinesterase, which is responsible for the catabolism of a neurotransmitter, acetylcholine.
On exposure to a nerve agent, the muscles of the body become paralyzed and early symptoms is production of excess mucous such as in runny nose, pupil constriction and also difficulty in breathing.
These agents are sometimes used in chemical warfare. Examples include sarin, tabun etc.
At first glance, it might seem counterintuitive with respect to energy use that many sharks must swim continuously or they will die. why is it important to their metabolic needs that sharks keep swimming? check all that apply.
Answer: seen below
Explanation:
This is because they have gills which function through the concurrent exchange of oxygen between the water and the blood of the sharks. This water passes over the gills in the opposite directional flow of the sharks blood in the gills. So the carbon dioxide concentration in the water outside their gills increases due to increase cellular respiration in their muscles.
Therefore, it is important that sharks must swim constantly in order to keep oxygen-rich water flowing over their gills.
Answer:
At first glance, it might seem counterintuitive with respect to energy use that many sharks must swim continuously or they will die. why is it important to their metabolic needs that sharks keep swimming? check all that apply.
The answer to the question above is explained below:
Explanation:
Gill involve external extensions from the body surface, it is the respiratory organ in many aquatic animals. They have feathery parts which cause water to move across the animal's body.
Gills are characterized by large amounts of surface area that function in gas exchange.
Sharks are type of fish that have no bones, only cartilage.
Why Sharks needs to keep swimming:
Sharks lack the swim bladder that most fish use to adjust their buoyancy. Swimming creates lift that prevents sharks from sinking.Sharks, like other marine animals, get their oxygen from the water. Nurse sharks, however, do have mechanisms to move water through their gills, and thus do not need to swim constantly to “breathe,Sharks use a ramjet ventilation system that requires them to swim to force water to the gills. Species that cannot pump water through their gills, they have to constantly swim to be able to breathe.Some sharks must swim constantly in order to keep oxygen-rich water flowing over their gills. This allows them to rest on the sea floor and still breathe. However, Some sharks, such as the tiger shark, can switch between buccal pumping and ram ventilation depending on quickly they're swimming.Carbon dioxide concentration in the water outside their gills increases due to the increased cellular respiration in their muscles.
Sharks have prominent spiracles, or respiratory openings behind the eyes that allow the fish to pull in water while buried under sand. Carbon dioxide waste also passes from the shark's blood and out of its body through the gill tissue.
As water passes over the gill's membranes, tiny blood vessels extract oxygen from the water.
