which organism is responsible for returning nutrients back to the soil
According to the research, decomposers are organisms responsible for returning nutrients back to the soil.
What are decomposers?They are different organisms such as bacteria and fungi whose main function is to break down the waste of plants and animals.
With the decomposition process where organic matter is processed into inorganic, simple elements (nutrients) reappear in the soil that are used as food by plants.
Therefore, we can conclude that according to the research, decomposers are organisms responsible for returning nutrients back to the soil.

Read the scenario.
A biologist sets up an experiment to see how different antibiotics affect the growth of the bacteria Clostridium perfringens. She grows colonies of the bacteria on four different Petri dishes filled with agar, a growth medium containing nutrients for the bacteria. She then applies a different antibiotic to three of the bacteria colonies in the Petri dishes. She leaves the fourth Petri dish to grow bacteria without any antibiotic.
Each Petri dish is the same size, contains the same nutrient agar, and is placed in an incubation chamber at the same temperature. At the end of the experiment, the biologist measures the diameter of the bacteria colonies on the Petri dishes.
Question
What factors must be kept constant in the experiment to obtain valid results?
size of the Petri dish, nutrient agar, diameter of the bacteria colony
bacteria species, type of antibiotic, diameter of the bacteria colony
type of antibiotic, nutrient agar, temperature
nutrient agar, temperature, bacteria species
Factors that must be kept constant in the experiment to obtain valid results are option (c) i.e, type of antibiotic, nutrient agar, and temperature.
what are antibiotics?A particular class of antimicrobial agents that works against bacteria is an antibiotic. Antibiotic drugs are frequently employed in the treatment and prevention of bacterial infections because they are the most effective type of antibacterial agent for doing so. Bacteria may be killed or have their growth suppressed.
They could harm the bacterial cell directly by attacking the cell wall. These cells can no longer do additional harm to the body since the bacteria cannot attack it. Other antibacterials, such as tetracycline and erythromycin, prevent the germs from multiplying or growing.
Antibiotics limit bacterial growth and replication by interfering with the bacterial cell wall. Because many types of bacteria have cell walls but human cells do not, antibiotics can kill bacteria while sparing human cells.

Design an imaginary food web or describe a real one. Include at least 4 living organisms that interact in your ecosystem.
The trophic web is the interaction between different organisms in which there is energy transference. In the attached example, we consider plants, beetle, rabbit, frog, eagle, fox, mountainlion, and fungi.
What is the trophic web?The trophic web is the interaction between different organisms involving transference of energy when some of them feed on the other ones.
The ones placed at lower levels pass energy to the ones at the higher levels.
Organisms at each level feed on the preceding one and become food for the next one.
• The first link corresponds to a producer organism -autotroph-.
• The following links are the consumers -heterotrophs- ⇒ herbivores and carnivores.
• The last links are the decomposers that degrade organic matter from dead organisms.
Because it is a web, all organisms are in equilibrium until a change occurs. When a sudden change affects any of the involved links, there can be a cascade effect on the web.
Any change in a link population size (increasing or decreasing) will affect the superior links and the immediately anterior link.
Example.
To make the trophic web, first, we need to have at least four links.
So first, let us list the organisms we are working with, and then define the position of each of the organisms on the web.
plants,beetle,rabbit,frog,fox,mountain lion, eagle,FungiProducer → this is the autotroph organism that takes energy from the sun or any other inorganic source → An example of this is any plant.
Consumers → heterotroph
⇒ Herbivores → These are the animals that feed on any part of the plants → These are the beetle and the rabbit
⇒ Carnivores → These are the animals that feed on herbivores → These are the frog, the fox, the eagle, and the mountain lion
Decomposer → detritivorous organisms that take energy from dead matter → Fungi
Trophic web,
Plants directly provide energy to the beetle and the rabbitPlant >> Beetle and Rabbit
The eagle takes energy from the rabbit and the frog takes energy from the beetle.Rabbit >> Eagle
Beetle >> Frog
The fox takes energy from the frog and from the rabbitFrog and rabbit >> Fox
The Fox and the eagle transmit energy to the mountain lion.Fox and Eagle >> Mountain lion
Fungi takes energy from dead organic matterPlants, beetle, Rabbit, Fox, Eagle, Mountain lion >> Fungi

ASAP PLS There are lots of big words in genetics! One way to start thinking about the process of meiosis is to ask yourself some questions.
If two parents are contributing genetic material to their offspring, why don’t the genes and chromosomes double in each generation?
If each parent has two sets of genes and chromosomes, why do their offspring receive only one set from each parent?
Answer:
1) the genes and chromosomes do not double after each generations because parental sex cells are haploid and only contain one set of chromosomes. During fertilization the two cells fuse to form a diploid zygote with two copies of genes and chromosomes. For example a normal human has 46 chromosomes (2 copies of 23 chromosomes) during reproduction gametes which contain 23 chromosomes (haploid) fuse to form an offspring with the correct number of chromosomes ( 23 + 23 = 46).
2) offspring only receive one set of chromosomes from each parent so to maintain the chromosome number of humans. If this did not happen you would not be the same species.
Explain why using different seed types along with different water temperatures is an improper experimental design.

What is the term for the measurement of how well a machine converts input
work into output work?
OA. Machinery
OB. Power
OC. Mechanical efficiency
OD. Work
Answer: OC. Mechanical Efficiency
Explanation: The percentage of user input (input work) that is converted into output work by a machine is known as efficiency (output work). The output work is never more than the input work because some of the input labour is used to remove friction. Efficiency therefore never approaches 100%.

Max's teacher use to gain the student's support by adding the obstacle of framing effect in the examinations. Thus, the correct option is C.
What is Framing effect?The framing effect is a cognitive bias in which the brain makes all the decisions about information depending upon how the information is presented to them. In this, people decide the options which were based on whether the options are presented with positive or negative connotations to them. For examples: the students doing examination.
People tend to avoid the risk when a positive frame is presented to them however they seek the risks when a negative frame is presented to them. Framing effect occurs when the decisions which people make are changed as a result of the way in which the outcomes are described to them.
Therefore, the correct option is C.

A particular ant species has four pairs of chromosomes. Identify genetic possibilities from independent assortment of a gamete
There are "256" different genetic combinations that a gamete may make by independent assortment.
What is meant by independent assortment?
Homologous chromosomes are allocated at random to daughter cells during meiosis, while distinct chromosomes segregate apart from one another. The term for this is independent assortment. It produces gametes with distinctive chromosomal arrangements.
Calculation:
Here, the number of chromosomal pairs in the ant = 4.
Every pair of chromosomes is going to be divided into a single gamete during the gametogenesis process.
Therefore, there are 4 unpaired chromosomes in all.
Now that the gametes lack paired chromosomes, they are haploid.
Now, a gamete would only contain one of the single chromosome pairs.
Let's assume that the chromosomal gene in the cell is heterozygous.
There are thus going to be options = 2.
Therefore, their likelihood will provide possibilities =2 x 2= 4.
Then there would be 4⁴ chromosomes = 256 chromosomes.
Therefore it is concluded that the genetic possibilities from the independent assortment of a gamete are "256".
