B. While detritivores feed on dead organic matter, decomposers actually break down dead or decaying organisms.
C. While detritivores consume animals, decomposers only consume plants.
D. While detritivores consume both plants and animals, decomposers only consume dead animals.

Question: "What is the difference between a detritivore and a decomposer?"
Answer: "Well, detritivores are known for feeding on dead 'organic matter'. Meanwhile, decomposers (like earthworms for example) actually break down all dead or decaying organisms. This being said, I would say out of the given options above, Option B would be the best answer."
Based on the explanation given, the difference between a detritivore and a decomposer is that while detritivores feed on dead organic matter, decomposers actually break down dead or decaying organisms externally.
What are detritrivores?A detritrivore is an organism which feeds on dead or decaying organic matter, especially plant detritus.
An example of a detritrivore is dung flies, millipedes, etc.
What is decomposer?A decomposer is an organisms which breaks down dead or decaying organic matter.

Answers
Rubidium is a soft, white metal that reacts with water similarly to sodium and potassium, but the reaction is much more violently exothermic.
What is a chemical reaction?When one or more chemicals are converted into one or more other chemicals, a chemical reaction occurs.
A chemical reaction is a practice that reverts one or even more substances, renowned as reactants, to one or even more various compounds, widely recognized as products.
Chemical elements or compounds are examples of substances.
Living things (cells, animals, humans, and insects) use chemical reactions to grow, develop, reproduce, and adapt.
Combination, decomposition, single-replacement, double-replacement, and combustion are the five basic types of chemical reactions.
Analyzing the reactants and products of a specific reaction will allow you to categorize it.
Rubidium is basically a soft, white metal that reacts with water in the same way that sodium as well as potassium do, but the reaction is much more exothermic.
Thus, rubidium and sodium are the two other elements that react the same way in a chemical reaction as potassium.

When an electric light is turned on, the amount of light energy released by the lightbulb is less than the amount of electrical energy going into the lightbulb. Which statement best explains this?
Question 4 options:
Some of the electrical energy is destroyed.
Some of the electrical energy is changed into heat energy.
Some of the electrical energy stays in the wire.
All of the electrical energy is destroyed.
Answers
Answer:
Some of the electrical energy is destroyed.
Explanation:
some of the electrical energy is destroyed because If the excess energy goes beyond the tolerance of the devices, they will overheat and/or burn (cause damage). ... If there is no interest in saving the extra energy, it can be "dumped" into an appropriate load and converted to heat.
When a lightbulb burns out, then that is when all of the electrical energy got desroyed, and that is why it happens over time
The statement that best explains this is some electrical energy is destroyed. The correct option is A.
What is electrical energy?Electrical energy is kinetic energy generated by moving electric charges. The amount of energy relies on the charge's speed; the faster it moves, the more electrical energy it carries.
Some electrical energy is destroyed because if the extra energy exceeds the devices' tolerance, they will overheat and/or burn (causing damage). If there is no desire to save the excess energy, it can be “dumped” onto a suitable load and transformed into heat.
When a lightbulb burns out, all of the electrical energy is destroyed, which is why it happens over time.
Therefore, the correct option is A. Some electrical energy is destroyed.

If the carrying capacity of the pond is 1,500 for this species, what is the expected population size after one year
Answers
Answer:
450
Explanation:
A fish population of 250 in a pond has a maximum annual rate of increase of 0.8. If the carrying capacity of the pond is 1,500 for this species, what is the expected population size after one year?
The annual rate of increase in the population is 0.8 and the population is currently 250 in the pond, hence, the expected population size after one year can be calculated as thus:
Expected increase in the population = 0.8 x 250
= 200
Expected population size after one year = 250 + 200
= 450
Since a population of 450 has not exceeded the carrying capacity of the pond, the expected population size after one year is, therefore, 450.
The expected population size after one year is 450
Data obtained from the question•Current population = 250
•Annual rate of increase = 0.8
•Expected population size =?
Determination of the expected increaseWe'll begin by calculating the expected increase in the pond. This can be obtained as follow:
•Current population = 250
•Rate of increase = 0.8
•Expected increase =?
Expected increase = Current population × rate
Expected increase = 250 × 0.8
Expected increase = 200
Determination of the Expected population size•Current population = 250
•Expected increase = 200
•Expected population size =?
Expected population size = Current population + Expected increase
Expected population size = 250 + 200
Expected population size = 450

During which step of the cell cycle does a cell get a signal to begin cell division?
Answers
Answer:
Prophase
Explanation:
Prophase is not only the first step of Mitosis and Meiosis (I and II), but it is crucial because it helps the chromatin become chromosomes, this is after Interphase where DNA replication occurs this is the signal that starts the dividing process. This phase also helps with condensing the chromosomes which acts as another signal to division because the chromosomes are prepared to be separated from one another. Spindle fibers (microtubules) are also created to get ready for separation. Now that these main things happened during Prophase, it signifies the rest of the cell and the other phases occur.

Gametes, which are sex cells, carry the alleles. Why must a gamete carry one allele (represented by a letter) from each gene? Meaning, why can’t a gamete carry an “hh” instead of an “hs” or an “Hh” instead of a “HS?”
Answers
Answer:
Due to the law of independent assortment
Explanation:
In diploid species like humans, all somatic (body) cells have two complete sets of chromosomes, one chromosome inherited from the maternal gamete and one chromosome inherited from the paternal gamete. Each one of the homologous chromosomes contains one copy of each gene, or allele, such that one allele is inherited from each parent. According to the law of independent assortment, maternal and paternal chromosomes are independently assorted during meiosis, which means that different genes localized on different chromosomes are randomly distributed into gametes. In consequence, alleles of different genes are transmitted from parents to offspring independently of one another.
