A relationship in which one species kills and consumes another species which is called as the Predation. So, the correct option is A.
What is Predation?Predation is defined as the relationship in which one species kills and consumes another species. It is a type of community relationship in which organisms of one species, also known as predator, consume the tissues of organisms of another species, called prey, which means killing the prey and killing all or most of the prey organisms.
Herbivores are explained as predators in which the prey organism is a plant. Predation is described as the natural way of transferring the energy fixed by plants to higher trophic such as snake eating a frog tiger killing and eating a deer.
Therefore, the correct option is A.

difference between incomplete and complete ventilation? any 4
Answer:
Due to exchange of gases i.e. normal and abnormal.
Explanation:
The main difference between incomplete and complete ventilation is the occurrence of normal and abnormal exchange of gases. The mechanism in which the exchange of gas happens completely without any difficulty is called complete ventilation. It is the process in which the required amount of oxygen is inhaled or inspired and appropriate amount of carbon dioxide is exhaled out of the body while on the other hand, incomplete ventilation is a mechanism in which exchange of gases is not normal.
The bacterium Methylophilus methylotrophus can use methanol and ammonia for protein synthesis. The glutamate dehydrogenase gene from E. coli was introduced into M. methylotrophus using recombinant DNA techniques. Under high ammonia conditions, the introduction of the glutamate dehydrogenase gene into M. methylotrophus resulted in an increase in protein yield. Select the statements that are reasonable explanations for the increased protein yield in the modified M. methylotrophus. Glutamate dehydrogenase catalyzes the formation of glutamate and glutamine in a two-step process. Both glutamate and glutamine play a key role in amino acid synthesis, thus an increase in levels of glutamate and glutamine increase protein synthesis. Glutamate dehydrogenase has a low affinity for NH^+_4, and can only catalyze the formation of glutamate from alpha-ketoglutarate and NH^+_4, when the concentration of NH^+_4 is high. Glutamate dehydrogenase has a high affinity for NH^+_4, thus the rate of glutamate synthesis increases exponentially under high ammonia conditions. Glutamate is the amino group donor for most transamination reactions involving amino acids, thus an increase in glutamate concentration increases protein synthesis.
Answer:
- Glutamate dehydrogenase has a low affinity for NH+4, and can only catalyze the formation of glutamate from alpha-ketoglutarate and NH+4, when the concentration of NH+4 is high.
- Glutamate is the amino group donor for most transamination reactions involving amino acids, thus an increase in glutamate concentration increases protein synthesis.
Explanation:
Glutamate dehydrogenase (GLDH) is an enzyme found in prokaryotic and eukaryotic cells, which is known to catalyze the reversible oxidative deamination of glutamate (Glu) to alpha-ketoglutarate and ammonia at the same time the oxidation of NADH to NAD. In bacteria, this enzyme (GLDH) is efficient only at high concentrations of the ammonium cation (NH4+), because it has a low affinity for NH4+. Moreover, transamination is a pathway that involves the transfer of an amino group from one amino acid to a ketoacid in order to form new amino acids (this reaction is responsible for the deamination of most amino acids). Glu is the donor of amino groups in most of the reactions catalyzed by enzymes involved in the transamination between an amino acid and an alpha-keto acid. In consequence, in presence of GLDH, a high concentration of Glu will increase the production of new amino acids and therefore also protein synthesis.
Excess postexercise oxygen consumption (EPOC) is also known as oxygen debt.
a. True
b. False
Answer:
True.
Explanation:
Excessive postexercise oxygen consumption can also be called oxygen deficit. It occurs after an individual completes a physical activity. Physical effort does not allow oxygen consumption to be normalized as soon as the body comes to rest and for this reason, the body begins to breathe and demand oxygen more intensely. This moment is known as excessive postexercise oxygen consumption, or oxygen debit. The intensity of breathing at this time will depend on the physical effort made, the weight loss and the increase in total caloric expenditure.

how many homologous pairs of chromosomes are present in a haploid cell that has 8 chromosomes and is in anaphase II of meiosis ll? explain your answer
Answer:
In many ways, meiosis is a lot like mitosis. The cell goes through similar stages and uses similar strategies to organize and separate chromosomes. In meiosis, however, the cell has a more complex task. It still needs to separate sister chromatids (the two halves of a duplicated chromosome), as in mitosis. But it must also separate homologous chromosomes, the similar but nonidentical chromosome pairs an organism receives from its two parents.
These goals are accomplished in meiosis using a two-step division process. Homologue pairs separate during a first round of cell division, called meiosis I. Sister chromatids separate during a second round, called meiosis II.
Since cell division occurs twice during meiosis, one starting cell can produce four gametes (eggs or sperm). In each round of division, cells go through four stages: prophase, metaphase, anaphase, and telophase.

Explain why you would recommend the nguni cattle meat to consumers in your locality.
Answer:
Below
Explanation:
All different combinations were catalogued in the beginning of the century by a South African herdmaster. This work inspired the Nguni Cattle Register, a compilation of terms to describe in full a Nguni cow or bull. The cattle are medium-sized, with bulls weighing between 500 and 600 kg,[3] while cows weigh between 300 and 400 kg.
If the initial ratio of 14C to 12C in the bones was one part per trillion (the current ratio of 14C to 12C in the atmosphere), approximately what ratio would we expect in bones that come from wolves trapped 28,500 years ago
Answer:
For the bones of wolves trapped 28,500 years ago, the approximate ratio of carbon-14 to carbon-12, 14C to 12C, will be one part per 32 trillion.
Explanation:
Radioactive isotopes of elements are useful for many purposes. Carbon has three isotopes, carbon-12, carbon-13, and carbon-14. Of these, carbon-14 is radioactive.
The half-life of an carbon-14 is used to determine the age of fossils in a process known as carbon-dating.
Carbon-14 has a half-life of approximately 5700 years. The half-life being the time for half the amount of the radioactive nuclei present in a radioactive element to decay.
The number of half-lives in 28500 years = 28500/57000 = 5 half-lives
This means that the original amount of atoms present in the atoms has undergone radiactive decay five times.
The ratio of the original amount of 14C to the present amount of 14C = (1/2)⁵ = 1/32
Ratio of 14C to 12C that will be found in the bones = 1/32 × 1/ 1 trillion = 1/32 trillion.
Therefore, for the bones of wolves trapped 28,500 years ago, the approximate ratio of carbon-14 to carbon-12, 14C to 12C, will be one part per 32 trillion.

How does the high specific heat of water help maintain the temperature of earth?
A By heating and cooling more slowly than land or air
B. By heating and cooling faster than land or air
с.
By heating faster but cooling more slowly than land or air
The high specific heat of water help maintain the temperature of the Earth by heating and cooling more slowly than land or air. Thus, the correct option is A.
What is the specific heat of water?The specific heat of an object is the amount of heat which is required to increase or raise the temperature of unit mass of that particular substance through one degree celsius. Specific heat is represented by the symbol 'c'. Its unit in SI system is Joule /(kg °C) and in CGS is cal / (gm °C).
The high specific heat of water helps in regulating the rate at which air changes its temperature, which is why the temperature of the planet change between different seasons is gradual rather than sudden, especially the geographical locations near the ocean.
Therefore, the correct option is A.
