B. point B
C. point A
D. point D
Answer:
The correct answer is option D. point D.
Explanation:
Carrying capacity is characterized as the maximum populace size that a domain can continue inconclusively. For most species, there are four factors that factor into figuring the carrying capacity of an individual population: food accessibility, water resources, habitat, and ecological conditions.
In a graph representation of population size in a time period increases until it reaches carrying capacity, carrying capacity is representing in the graph where the increase in curve becomes stable and makes a plateau.
Thus, the correct answer is option D. point D.
Answer:
D point D
Explanation:
The last universal common ancestor (LUCA) is the most recent organism from which all organisms on Earth descended. While it is challenging to definitively determine the specific characteristics of LUCA, scientists have proposed certain properties that it likely possessed based on evolutionary and genetic evidence. Let's analyze each property mentioned in the question:
1. Simple cellular structure:
- LUCA is believed to have had a simple cellular structure. This means it likely had basic cellular components, such as a cell membrane, cytoplasm, and possibly some form of genetic material.
2. Anaerobic metabolism:
- LUCA is thought to have relied on anaerobic metabolism, which means it obtained energy from sources other than oxygen. This is because molecular oxygen was not abundant in the early Earth's atmosphere when LUCA is believed to have existed.
3. Prokaryotic cell type:
- It is widely accepted that LUCA was a prokaryote, meaning it had cells lacking a nucleus or other membrane-bound organelles. Prokaryotes are considered the most ancient type of cells on Earth.
4. Extremophile characteristics:
- While it is difficult to determine the specific environmental conditions in which LUCA lived, some scientists propose that it could have been an extremophile, capable of surviving in extreme environments like high temperatures, high salinity, or acidic conditions. However, this is still a topic of scientific debate and further research is needed.
5. Heterotrophic nutritional strategy:
- LUCA is believed to have been heterotrophic, meaning it obtained nutrients by consuming organic compounds produced by other organisms. This is in contrast to autotrophs, which can produce their own food through processes like photosynthesis.
In conclusion, based on current scientific understanding, LUCA is likely to have possessed the properties of a simple cellular structure, anaerobic metabolism, prokaryotic cell type, and a heterotrophic nutritional strategy. The presence of extremophile characteristics is still a subject of ongoing research and scientific investigation.
I hope this explanation clarifies the properties that LUCA is believed to have had. Let me know if you have any further questions.
B. 2.48 MJ
C. 3.09 MJ
D. 2.13 MJ
I think the answer is B. 2.48 MJ, correct me if I’m wrong I’m studying this
The body's reaction to information is to send neurons to the brain. This can be facilitated by the transmission of nerve impulses throughout the body with the help of neurons.
Neurons may be characterized as nerve cells that significantly sends or receives signal to and from the brain. These cells typically communicated with other cells of the body with the help of a junction which is known as a Synapse.
According to the physiology of the function of neurons, sensory neurons perceive as a set of information or messages from various sense organs like eyes, ears, nose, tongue, and skin and send them directly to the brain.
While the function of motor neurons is understood by the fact that these neurons send the perceived information and messages from the brain to the entire body at the target site.
Therefore, the body's reaction to information is to send neurons to the brain.

Answer:
The law of mass action and molecular concentration
Explanation:
Law of mass action: According to this law, the rate of chemical reaction is directly proportional to the masses of the reacting substance, at a constant temperature.
Molecular concentration: It is no of moles of solute dissolved in a liter of solution. No of molecules of reactants increases when we increase the molecular concentration of the reactant, which in turn increases the frequency of collision and hence the rate of reaction and direction.
