Answer:
Please find the explanation of independent and dependent variables below using the experiment in this question.
Explanation:
Independent variable is the variable that the experimenter changes or manipulates in an experiment while the dependent variable is the variable being measured in the experiment.
According to this question, a biology student who has grown tomato plants for several years wants to know whether using natural compost will cause his tomato plants to grow faster and taller than his artificial fertilizer, which he used previously.
In this case, the "natural compost" is the independent variable while the dependent variable is how tall and fast the tomato plant will grow. Hence, the tallness or fastness is the dependent variable.

What is the relationship between Distance and average number of species?
Answer: The relationship between species and distance is that more distance or space has more species and less space has less species.
Explanation:
It can easily be understood by taking the example of the island in such a way that the larger islands contains more species than smaller islands.
There are a diversity of species seen in a bigger islands, more in number and more in variety.
It is very important for the studying the various species and its conservation, protection and other factors.
So, more is the distance , more will be the number of species.

In the testes, sperm cells replicate and differentiate in the _________. Question 2 options: urethra septum tunica albuginea seminiferous tubules ductus deferens
Answer:
seminiferous tubules
Explanation:
Seminiferous tubules are coiled tubes where sperm cells are produced by a process referred to as spermatogenesis. These tubes are located in the testes or testicles (i.e., male reproductive glands/gonads). Each testicle contains approximately 250 compartments known as testicular lobules, while each testicular lobule has 1 to 4 seminiferous tubules which converge to form a single straight tubule. Once sperm cells mature, they travel through the seminiferous tubules to be stored in a coiled tube called the epididymis.

What are the possible benefits of hybridization?
Answer:
Advantages of hybridization include passing along favorable traits and prolonging the survival of a threatened or endangered species, but a disadvantage is that hybrid animals have more difficulty finding mates and successfully breeding. Hybridization occurs naturally and through human initiation.

If the sodium/potassium ion pump were to stop functioning, what would eventually happen to the concentration gradients of sodium and potassium ions across the membrane
Answer:
The correct answer would be - concentration gradient will reach to equilibrium.
Explanation:
If the Na+/K= ion pump stops working which is to pump the sodium and potassium ion across the cell membrane. The movement takes place in 3:2 ratio with the help of ATP.
Eventually, the concentration gradients of sodium and potassium would be equal and found equilibrium across the membrane. This equilibrium would be reached due to passive transport that occurs in either direction across the membrane.

5. What would be the effect if a gene has a mutation in the location of the stop codon? (4 points)
During translation protein synthesis won't stop when it should so amino acids will continue to be placed and the peptide will be bigger.
Answer:
In genetics, a point-nonsense mutation is a point mutation in a sequence of DNA that results in a premature stop codon, or a point-nonsense codon in the transcribed mRNA, and in a truncated, incomplete, and usually nonfunctional protein product.

What is the medical term for the process or procedure that destroys or inhibits disease-causing microorganisms to prevent infection:
Answer: Sterilization.
Explanation:
Sterilization is the process that kills, or deactivates all forms of life so then a product is considered free of viable microorganisms. This process must be designed, validated and carried out to ensure that it is capable of eliminating the microbial load of the product.
Since sterility cannot be demonstrated without causing the complete destruction of the products, sterility is considered when the probability of a product being contaminated is acceptably remote. A critical product is considered sterile when the probability of a microorganism being present in an active or latent form is equal to or less than 1 in 1,000,000 (sterility safety factor 10^-6).
Agents that kill microorganisms are called microbicides or more commonly called "germicides". If the agent kills bacteria, it is called a bactericide. And if it kills fungi, then it is called a fungicide. It is important to consider than after an exposure of the sterilized object to the air or its surroundings, it will have become contaminated again with microorganisms.
Examples of sterilization include physical methods and chemical methods. Physical methods include:
Wet heat (in steam autoclave) Dry heat (in sterilization oven) Radiation (gamma radiatio, electron beam, X-ray, ultraviolet, microwave, white light)Chemical methods include a variety of chemicals in liquid and vapor form, for example:
Hydrogen peroxideChlorine dioxideOzone gasesEthylene oxidePropylene oxidePeracetic acidRejection occurs when the recipient’s immune system recognizes the donor tissue as foreign
