Malaria develops resistance to anti-malarial medications due to antibiotic use. The P. falciparum malaria oarasite is evolving drug resistance.

Just two of the four adult malaria parasite species, Plasmodium falciparum & P. malariae, have been demonstrated to be resistant to anti-malarial medications currently on the market. Inadequate therapeutic treatment options of active infectious diseases, overuse of anti - malarial drugs for prophylaxis, a high level of parasite ability to adapt at the metabolic and genetic levels, as well as a massive proliferation rate which permits selection are some of the causes of resistance to malaria parasites. The causes of this pattern are unknown, but two possible explanations are tenable: earlier initiation of resistance due to more frequent migration patterns between East Africa and Asia, the region where highly resistant parasites are most frequently found; and faster spread of mutations due to higher.

B. genetic material
C. energy storage
D. cell waste

Answers

Answer:

C

Explanation:

ATP has to do with energy so the correct answer would be energy storage.

The one that describes ATP is energy storage. The correct option is C.

What is ATP?

A chemical that is a part of all living cells and gives energy to a variety of metabolic processes, including the production of RNA.

In patients with advanced solid tumors, the effects of laboratory-produced ATP on weight loss and muscle strength are being investigated. Likewise known as adenosine triphosphate.

The principal energy source for critical biological processes such muscular contraction, nerve impulse transmission, and protein synthesis is ATP generated in mitochondria.

For example, large levels of ATP signal that the cell has enough ATP and does not need to produce any more through cellular respiration. In this instance, a product "feeds back" to block its pathway, which is a form of feedback inhibition.

Thus, the correct option is C.

How might an ecologist test whether a species is occupying its complete fundamental niche or only a portion of it

Answers

By conducting this analysis, an ecologist can better understand the relationship between a species and its environment,

and make informed decisions about conservation and management efforts. An ecologist might test whether a species is occupying its complete fundamental niche or only a portion of it by following these

steps: 1. Identify the species: First, the ecologist needs to determine the specific species they want to study.



2. Define the fundamental niche: The ecologist will establish the range of environmental conditions (e.g., temperature, moisture, resource availability) under which the species can survive and reproduce, based on their knowledge of the species' biology and ecological requirements.



3. Observe the species' distribution: The ecologist will collect data on the species' current distribution in the ecosystem, documenting where the species is found and the environmental conditions in those locations.



4. Compare the fundamental niche to the realized niche: The realized niche is the actual set of conditions under which the species is observed to survive and reproduce in the field.

By comparing the fundamental niche (theoretical) to the realized niche (observed), the ecologist can determine if the species is occupying its complete fundamental niche or only a portion of it.



5. Investigate limiting factors: If the species is found to be occupying only a portion of its fundamental niche, the ecologist will investigate potential factors that may be limiting its distribution, such as competition, predation, or human disturbance.


By conducting this analysis, an ecologist can better understand the relationship between a species and its environment, and make informed decisions about conservation and management efforts.

microtubules start at the centrosome and then connect to the kinetochores, which are structures at the central region of chromosomes

Answers

Microtubules start at the centrosome and then connect to the kinetochores, which are structures at the central region of chromosomes. The centrosome is the main microtubule-organizing center (MTOC) in most animal cells, whereas plant cells lack a typical centrosome.

The two spindle poles are the central region of a chromosome where a kinetochore is connected. Microtubules are a type of cytoskeletal protein filament that plays a crucial role in the mechanics of cell division.

Microtubules, together with actin and intermediate filaments, form the cytoskeleton, which is the structural framework of the cell. Microtubules also transport vesicles and organelles, support cell shape, and mediate cell signaling.

They are also crucial in cell division, serving as a framework for the mitotic spindle, a structure that segregates chromosomes during cell division.

how are dideoxynucleotides (ddntps) different from dna nucleotides and why are ddntps needed in dna sequencing? group of answer choices ddntps are the same as dna nucleotides but have a radioactively labelled nucleotide and are used interchangeably with regular nucleotides. there is only one ddntp instead of 4 different ones and are used in terminating dna synthesis. there is no difference between the two nucleotides and ddntps can be used instead of dna nucleotides during dna sequencing. ddntps have a hydrogen at the 3' position instead of an oh group and are used to terminate dna synthesis. ddntps have an extra oh group at the 2' position and are used to terminate dna synthesis.

Answers

Dideoxynucleotides (ddNTPs) are different from DNA nucleotides in that they have a hydrogen atom at the 3' position instead of an OH group. In DNA sequencing, ddNTPs are used because they terminate DNA synthesis.

They lack a hydroxyl group (-OH) on the 3' carbon atom of the deoxyribose sugar, which is required for the formation of a phosphodiester bond between nucleotides. As a result, when a ddNTP is incorporated into a DNA strand, it cannot bind to the next nucleotide because it is missing the 3' OH group, and synthesis stops.

This results in a set of DNA fragments of varying lengths that are complementary to the original DNA strand and are a measure of its sequence. Therefore, ddNTPs are required in DNA sequencing to allow researchers to read the DNA sequence of a specific gene.

Target BCS at the end of the peak lactation or end of the NEB period is 1.5 2.0 2.5 3.0 How long can you feed colostrum and get any sort of immunoglobulin absorption? 6 hrs. 12 hrs. 24 hrs.

Answers

The target BCS (Body Condition Score) at the end of the peak lactation or end of the NEB (Negative Energy Balance) period may vary depending on specific management goals and individual animal requirements. As for the duration of colostrum feeding for immunoglobulin absorption, the recommended timeframe is within the first 24 hours after birth.

Feeding colostrum to newborn animals is crucial for their passive transfer of immunity. Colostrum contains high concentrations of immunoglobulins, which are essential for providing temporary protection against diseases until the newborn's own immune system develops. It is generally recommended to feed colostrum within the first 6 to 12 hours after birth to ensure optimal absorption of immunoglobulins. However, absorption can still occur to some extent within the first 24 hours. After this period, the intestinal absorption of immunoglobulins diminishes significantly, reducing the effectiveness of colostrum as a source of passive immunity. Therefore, it is important to provide colostrum to newborn animals as early as possible to maximize immunoglobulin absorption and improve their overall health and disease resistance.

The molar ratios [A] = [T] and [C] = [G] were present in all species, and the ratio [C + G] / [A + T] was often lower than unity since [C + G] is a less common element. And Chargaff's rule name is given to these ratios.

Additionally, the molar similarities of A with T and C with G naturally support a certain type of combination link. Furthermore, Chargaff himself is unwilling to take a chance on claims of his experimental observation in the absence of new experimental ideas.

Additionally, he believed that Watson and Crick's model-building strategy was not grounded in science. Most notably, he later disparaged molecular biology in general and eventually grew frustrated at what he perceived as a refusal to acknowledge the significance of his work.

Therefore, in this case, 30% is Adenine and 30% will be Thymine, so the remaining 40% will be GC, out of which 20% will be Guanine.

Answers

Answer:

the state of maintaining a stable internal environment despite changing external conditions

Explanation:

homeostasis is all about regulating, whether it be regulating body temperature through shivering, regulating body water levels, etc..

The best description of homeostasis is "the state of maintaining a stable internal environment despite changing external conditions." Homeostasis is a vital physiological process that helps to maintain the internal environment of an organism.

What is homeostasis?

To achieve homeostasis, the body uses various physiological and biochemical mechanisms to monitor and respond to changes in the external environment. For example, if the external temperature becomes too high, the body will respond by sweating to cool down and maintain a stable internal temperature. Similarly, if the blood pH becomes too acidic, the body will respond by increasing the excretion of hydrogen ions to restore a more neutral pH.

Hence, the best description of homeostasis is "the state of maintaining a stable internal environment despite changing external conditions."

ii) Rusting occurs most in tube 1 because both air and water which are necessary for rusting are present.

Explanation:

Rusting is a chemical change which involves a redox reaction. During the process of rusting, metallic iron is oxidized to hydrated iron (iii) oxide by oxygen present in air.

For rusting to take place effectively, each of these three factors mist be available: metallic iron, oxygen and water.

In the figure above, the iron nails in the three tester tubes will rust to different extents based on the availability of the three factors.

In test tube 1, the iron nails will rust the most because all the three factors: metallic iron, oxygen present in air, and water are abundantly present.

In test tube 2, the iron nails will rust the least or not at all because boiling of water removes dissolved oxygen from water and the oil layer above the boiled water prevents entry of oxygen from air. Thus, the nail do not rust because one of the three factors for rusting to take place, in this instance, oxygen is absent.

In test tube 3, the iron nails rusts the least or not at all as well because moisture or water is absent. Calcium chloride, a drying agent removes all the moisture from inside the tube. Hence, even though air is present, rusting do not occur as there is no moisture or water present.
