Answer:

and got tooka killed Explanation:
The amount of energy at each trophic level in an ecosystem decreases as it moves through the ecosystem. Typically, only about 10 percent of the energy at one trophic level is transferred to the next level. The remaining energy is lost through metabolic processes as heat.
Suppose that, in the ecosystem modeled above, 150,000 kcal (kilocalories) of energy are contained within green plants. Assuming that the amount of energy transferred from one trophic level to the next is exactly 10 percent, determine the following amounts of energy in the ecosystem.
Answer:
Explanation:
Energy transferred to next trophic level=10%×150,000kcal
=10/100×150,000
=15,000kcal
The amount of the energy in the ecosystem should be considered as the 15,000kcal.
Calculation of the amount of energy:Since there is 150,000 kcal (kilocalories) of energy are contained within green plants.
And, 10 percent of the energy at one trophic level is transferred to the next level.
So here the amount of energy be like
= 10% of 150,000
= 15,000 kcal
Hence, The amount of the energy in the ecosystem should be considered as the 15,000kcal.

Answer:
Which class of RNA is correctly paired with its function? Transfer RNA (tRNA): attaches to an amino acid. What is the difference between the template strand and the nontemplate strand? The template strand is the DNA strand that is transcribed into an RNA molecule, whereas the nontemplate strand is not transcribed
why is reproductive isolation insufficient to define a species?
A. This definition overlooks artificial preproduction, such as in zoos
B. Reproductive isolation doesn't take outgroups into account
C. This definition excludes organisms that reproduce asexually
D. Reproductive isolation can be accomplished in a variety of ways
The correct option is (c) This definition excludes organisms that reproduce asexually.
Asexual reproduction is also possible in bacteria, yeast, fungi, plants, and other organisms. Most frequently, yeast proliferate by budding. Plants and fungi both use spores for asexual reproduction. Additionally, plants are capable of reproducing asexually by vegetative propagation.Numerous eukaryotic creatures, such as plants, animals, and fungus, are also capable of asexual reproduction. Parthenogenesis, the most prevalent type of asexual reproduction in vertebrates, is frequently employed as an alternative to sexual reproduction when sexual reproduction isn't an option.What are the 4 types of asexual reproduction?Asexual reproduction includes fission, budding, fragmentation, and parthenogenesis, while sexual reproduction is achieved through the combination of reproductive cells from two individuals.

Why are most systems in the human body negative feedback systems?
Most systems in the human body are negative feedback systems because negative feedback systems allow humans to regulate and stabilize their systems, which is the first option as a negative feedback system regulates the body's functioning.
What is the negative feedback system?Negative feedback is a regulatory mechanism in which a change in a physiological variable triggers a response that opposes the initial change, for example, in the regulation of body temperature, when the body becomes too hot, thermoreceptors in the skin and other tissues detect the change in temperature and send signals to the hypothalamus, which acts as the body's thermostat and as a feedback mechanism, hypothalamus triggers responses that cool the body, such as vasodilation to increase blood flow to the skin, sweating to release heat, etc.
Hence, most systems in the human body are negative feedback systems because negative feedback systems allow humans to regulate and stabilize their systems, which is the first option.

Explanation:
What is the primary mechanism associated with the role of fluoride in prevention of dental caries? a. Fluoride increases calcium absorption, which increases crystal formation of teeth b. Fluoride increases salivation which aids in the removal of bacteria and the foods needed to sustain bacterial growth c. Decay is reduced due to the inhibitory effects of fluoride on growth of bacteria on the teeth d. Fluoride becomes incorporated into the crystalline structure of teeth, making them less susceptible to decay e. Decay is inhibited due to neutralization of organic acids produced by bacteria on the teeth
Answer:
d. Fluoride becomes incorporated into the crystalline structure of teeth, making them less susceptible to decay
Explanation:
Dental caries results when cariogenic (caries-causing) bacteria metabolize carbohydrates or sugars present in the mouth for their energy needs, producing organic acids as byproducts, thus lowering the pH of the plaque biofilm.
The hydroxyapatite of tooth enamel is composed mainly of phosphate ions (PO₄³⁻) and calcium ions (Ca⁺). Under normal conditions, there is a stable equilibrium between the calcium and phosphate ions in saliva and the crystalline hydroxyapatite. At low pH (acidic conditions), there is a shift in equilibrium resulting in the dissolution of hydroxyapatite from tooth enamel, a process known as demineralization. A reverse process called remineralization (the process of incorporation of minerals in tooth enamel) occurs when the saliva, acting as a buffer elevates pH. When equilibrium is shifted to favor continued demineralization, dental caries results.
However, when fluoride is present in saliva, fluorapatite, rather than hydroxyapatite, forms during the remineralization process as fluoride ions replace hydroxyl groups in the formation of the apatite crystal lattice.
Fluorapatite is less soluble than hydroxyapatite making it more resistant to demineralization, even under conditions of low pH. Thus, fluoride acts as an effective anticaries agent.

1.) A person walks 12.5 km in 1.9 h. What is the person's
average velocity in km/h and m/s?
Answer:
1. 6.56 km/hr
2. 1.83 m/s
Explanation:
The average velocity/speed can be calculated using the formula;
Average speed/velocity = distance/time
According to the information provided in the question, distance = 12.5km, time = 1.9h
Average velocity in km/hr = 12.5/1.9
= 6.578
= 6.56km/hr
However, in order to calculate the average speed in m/s, we have to convert distance in km to m, and time in hour to seconds.
1km = 1000m
12.5km = 12.5 × 1000
= 12500m
1 hour = 3600seconds
1.9hours = 1.9 × 3600
= 6840seconds
Average velocity = 12500/6840
= 1.827
= 1.83m/s

Answer:
Scotland
Law is a surname, of English, Scottish, Cantonese, or Chinese origin. In Scotland, the surname means dweller at the low; as in a hill. Another origin of the surname is a contraction of Lawrence, or Lawson.
Explanation:
Answer:When recombination occurs during meiosis, the cell's homologous chromosomes line up extremely close to one another. Then, the DNA strand within each chromosome breaks in the exact same location, leaving two free ends. Each end then crosses over into the other chromosome and forms a connection called a chiasma.

A newly identified virus infects a eukaryotic host cell without producing virions right away, with a long period where the host is largely unaffected by the infection. What's the best description of this virus?
A: This virus rapidly causes lysis of the host cell
B: This virus has a long period of latency
C: This virus is a bacteriophage
D: This virus can't replicate
The best description of the virus is that the virus cannot replicate. The correct option is D.
What is a virus?A virus is an infectious agent which is non-living normally, but it becomes alive when come in contact with any living cell. It causes many diseases in humans, animals, and plants.
Here, the virus is not producing virions, which means it doesn't cause lysis. It doesn't affect the host, so do not have a long period of latency, and is not a bacteriophage, so the virus is not replicating.
Thus, option D: This virus can't replicate is correct.
