Many farmers and gardeners compost their plant and animal waste. The living material naturally decays in
compost bins, forming a dirt-like substance that's rich in nutrients. The next season, farmers use this
substance as a natural fertilizer for their crops.
A biology student has grown tomato plants for several years. Until now, he used an artificial fertilizer
formulated for tomato plants. This fertilizer caused his plants to grow faster and taller than they grew in
unfertilized soil. The student wants to know whether using natural compost will cause his tomato plants to
grow faster and taller than his artificial fertilizer. Explain independent and dependent variables

Answers

Answer 1

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.

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

Answers

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.

What is the medical term for the process or procedure that destroys or inhibits disease-causing microorganisms to prevent infection:

Answers

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 acid

Answers

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.
