Answer:
Control group - the plant group which has not received the fertilizers treatment.
Experimental group- the groups treated with different varieties of fertilizers.
Independent variable- amount of water and fertilizers
Dependent variable- growth of plants
Explanation:
A scientific experiment is performed in a way that the experimental samples are classified into the control and experimental groups. Also, the experiment involves various variables to be studied which can be classified as an independent variable and dependent variable.
In the given question, the experimental samples are:
1. Control group- The samples which are not provided with the variable being studied like the experiment is performed to test the effect of fertilizers and "the plant group which has not received the fertilizers treatment" can be considered the control group.
2. Experimental group- the samples in which the variable to be studied are provided with that is "the groups treated with different varieties of fertilizers."
In the given question, the variables are:
1. Independent variable- the variable which can be changed or modified or can change on their own like "amount of water and fertilizers" in the experiment.
2. Dependent variable- the variable which is being tested, can be measured and is dependent on an independent variable like the " growth of plants" in the experiment.
Which of the following is an indicator of chemical change?
a change in phase of the materials
a change in the shape of the materials
a change in the volume of the materials
a change in the temperature of the materials
Answer: a change in the temperature of the materials

What is a Schwarzchild radius and what does it have to do with a black hole
Answer:
The Schwarzschild radius (sometimes historically referred to as the gravitational radius) is a physical parameter that shows up in the Schwarzschild solution to Einstein's field equations, corresponding to the radius defining the event horizon of a Schwarzschild black hole
Explanation:
The Schwarzschild radius define the “size” of a black hole. Theorists believe that all the “stuff” inside a black hole collapses into a singularity, an infinitely small and infinitely dense point well inside the boundary defined by the Schwarzschild radius.

What term describes a species whose removal would affect many other species, both directly and indirectly
A. predator species
B. Keystone species
OC. cascading species
OD. phoresy species
Next
Answer:
Keystone species
Explanation:
Keystone species is that species whose presence and number in the ecosystem plays an important role in balancing the ecosystem and without them, the other species would be affected directly and indirectly.
A dominant predator is considered to be a keystone species because the removal of that predator allow their prey to explode in numbers which will decrease the overall biodiversity of the area. Prairie dogs, otters, bison are the examples of keystone species. So the correct answer is B. Key stone species.

write a paragraph to show your knowledge about diabetes that include the following terms:
Glucose, Glucagon, Pancreas, Negative Feedback, Homeostasis, and Liver
Answer:
Glucose is a simple sugar molecule that helps play a role in high/low blood sugar levels. If your blood level is too low Glucagon is released to increase your blood sugar and if it’s too high Insulin is secreted to lower blood sugar; both Insulin and Glucagon are hormones.This being said these two hormones are secreted by the pancreas. Both of these two hormones are examples of negative feedback leading to a stability In homeostasis. It is regulated by the liver, however if homeostasis is disrupted the body will stop functioning properly leaving no insulin to be produced. Therefore the end result is Diabetes

Seth will attend college in the fall and live in the dormitory, so he is required to obtain a blank against bacterial meningitis, which will stimulate his body to produce immunity to the disease. He reads that meningitis is a fast-acting and potentially fatal disease, transmitted by blank in the respiratory droplets of infected individuals. The bacteria are blank that cause disease by destroying blank and releasing blank that disrupt the body’s normal homeostasis. Bacterial infections are treated with blank , which block the growth and reproduction of bacteria.
Key answer: bacteria, vaccine, cells, pathogens, toxins, antibiotics
Answer:
vaccine
bacteria
pathogens
cells
toxins
antibiotics
Explanation:
Bacterial meningitis is a serious disease that is caused by an infection which results into Inflammation of brain and spinal cord membranes.
It is generally caused by virus but also caused by fungus and bacteria. A vaccine is required to fight against the bacterial meningitis. Symptoms include fever, stiff neck and headache. This disease is carried by the bacteria present in the throat of infectious person and can transmit through coughing, sneezing and kissing. The bacteria are the pathogens, releases a toxin which destroy cells and surface components of nervous system.
This disease is treated with intravenous antibiotics and corticosteroids (sometimes).
Hence, the correct answers for blanks are vaccine, bacteria, pathogens, cells, toxins, and antibiotics in sequential order.
After removing a cutting from a parent plant, farmers usually:
Answer:
Plant the cutting in a different location
Explanation:
A cutting is a piece of a plant that is usually cut by farmers during agricultural practices. It is a means of vegetative (asexual) propagation.
The part of the plant which is cut is usually the stem or root of the parent plant. The cutting is then placed in a favorable environment which is mostly moist soil for proper growth .

What part of the respiratory tract is considered the respiratory zone?
A. Bronchioles
B. Larynx
C. Trachea
D. Alveoli
Answer:
D. Alveoli
Explanation:
Functionally, the respiratory system is separated into a conducting zone and respiratory zone:
Conducting zone consists of the nose, pharynx, larynx, trachea, bronchi, and bronchioles. These structures form a continuous passageway for air to move in and out of the lungs.
Respiratory zone is found deep inside the lungs and is made up of the respiratory bronchioles, alveolar ducts, and alveoli. These thin-walled structures allow inhaled oxygen (O2) to diffuse into the lung capillaries in exchange for carbon dioxide (CO2).
The respiratory zone begins where the terminal bronchioles join a respiratory bronchiole, the smallest type of bronchiole, which then leads to an alveolar duct, opening into a cluster of alveoli.
Answer:
Yep, the correct answer is D.) Alveoli
Explanation:
Hope this helped you!Have a great day(:

Alternate forms of a gene having the same position on a pair of chromosomes and affecting the same trait
are called ______. A) phenotypes B) alleles
C) DNA
D) mutations E) genotypes
Answer:
The answer is B) alleles
Explanation:
Alternate forms of a gene having the same position on a pair of chromosomes and affecting the same trait are called alleles.
What do you mean by traits?Traits may be defined as the appearance or manifestation of the desired characters. Traits are also known as phenotypes.
Every factor or gene has two alternative copies, one comes from the father and one comes from the mother. These two copies are present in the same location on the homologous chromosome. They are known as alleles of each other.
Therefore, Alternate forms of a gene having the same position on a pair of chromosomes and affecting the same trait are called alleles.

Answer: 1: allergic disorders
2. Immunodeficiency disorders
3. Autoimmune disorders
4. Cancers
Immune system overreacts to an antigen part of the immune system does not function properly the body's immune system attacks its healthy cells, mistaking them for pathogens masses of cells form and steal nutrients from healthy.
What do you mean by Allergy?Allergy may be defined as a reaction by our immune system to something that does not trouble most other people. It affects a person more specifically.
When a person gets affected by any allergy, the immune system of that person may overreact by producing more antibodies. These antibodies attack the allergen particles and cause adverse symptoms.
A person who has allergies has them because his or her body over reacts to a material that would otherwise be ignored. It is an overreaction of the immune system triggering a immune attack response that is unneeded.
Therefore, a person who has allergies has a compromised immune system because the body's immune system overreacts to an antigen.
