what represents the control group
Answer:
which control group are you talking about?
Answer:
A control group shall be the subject group without treatment or standard treatment. The Control group shall be the subject group. Nothing would be compared to the treatment group without the control group. Where statistics refer to "X times higher" the difference in measures between the treatment group and the control group is referred to. A basic feature in the experiment is the control group.
Explanation:
Exactly the same conditions as therapy groups will apply to the control group. This makes it possible to measure only the effects produced by the variable. For example, in a plant study, each plant would ideally be in the same space, under the same conditions of light and air.
Control groups are also used when medicines are tested on humans. While control groups were only considered to be good science, drug trials found an interesting phenomenon. Control groups are frequently found in drug studies in people who have a disease or ailment but are not tested for the medicine.
A fake medicine is given to the control group, and patients begin to see findings. This is called placebo by scientists and is still mainly unexplained. Some scientists suggested that people improve simply because they thought they would get better, but this theory is not tested.

What are some advantages and disadvantage for cloning
Answer:
Advantages:
1.) You can run tests on the experimental clones. This will help treat diseases that are specific to each individual.
2.) You can increase the number of test subjects. This will significantly improve efficiency.
3.) You can test different cures on different subjects that have the same DNA.
Disadvantages:
1.) It is morally wrong. You likely are only cloning for two reasons: to "bring back" somebody's loved one (or important person in society) or you are doing it for experimental purposes. These organisms are NOT the same as the originals, so you are only doing it for selfish reasons.
2.) It is "playing God." This means that you are creating another life that should have only been lived once. Although the new organism has its own thoughts and feelings, there is already another one of it that exists or has existed.

Answer:
Geology involves integration of various different sciences (chemistry, physics, and biology for example), but also requires an understanding of the importance of billions of years of geological time.
Paleontology is an important aspect of geology and requires an understanding of biology, including evolution, the physiology of animals and plants and ecological relationships.
Research since Mendel's time has established that the law of segregation of genes during gamete formation Research since Mendel's time has established that the law of segregation of genes during gamete formation applies to all sexually reproducing organisms. applies to all asexually reproducing organisms. applies to all forms of life.
Answer:
applies to all sexually reproducing organisms.
Explanation:
The law of segregation of genes applies to all sexually reproducing organisms because segregation occurs in the gametes. The Mendelian trait alleles may be dominant or recessive and they will passed down from parent to child. In plants, for example, the color trait of the flower will depend on the type of allele inherited by the offspring. Each parent plant transfers one of the alleles to their offspring and the dominant allele shows itself in the appearance.
Answer:
The correct answer is: applies to all sexually reproducing organisms.
Explanation:
Mendel's laws of segregation are a group of basic rules that explain how gene transmission (inheritance) occurs from parents to children in every species that reproduces sexually and constitute the foundation of Genetics.
Diploid species, such as rats or humans, for example, possess two sets of chromosomes, one that comes from our mother and one that comes from our father. To make the perpetuation of species possible, diploid individuals produce, through a process called Meiosis, sex cells called gametes - which contain only one set of chromosomes (each chromosome will have only one copy of each gene) that will add up to another set of chromosomes when they encounter another gamete from the opposite sex.
Each chromosome will have specific genes, and these genes can manifest in different variations that are called alleles. Depending on the alleles present in the chromosomes that we inherited from our mother and father, the gene will express itself in one way or another. This is thanks to the law of segregation that states that each gamete randomly receives one allele for each gene.
Individuals that reproduce asexually do not produce gametes; their progeny is identical to themselves, This is why Mendel's laws of segregation only apply to species that reproduce sexually and not all living organisms.
A force of 200N is applied to an object with a mass of 15kg. What is its acceleration?
Answer:
Force = mass x acceleration
So Acceleration = Force / mass
Given,
Force= 200 N
Mass = 15kg
SO, Acceleration= 200/15 m/s
=13.33 m/s

Answer:
most likely B and you know why? native plants are more dangerous!!!
Explanation:
yes that is my explanation, i learned this in like middle school.
If left unattended, non-native plants can take over the area and kill the native plants. Thus, the correct option is A.
What is no mow zone?A “no mow zone” is refer as a designated section of land purposely not mowed in order to encourage native plant species growth. If left alone for a century or longer, the lawn will transform into a forest.
Low mow zones are ideal habitats for small animals and insects and become rich with species.

describe the difference between covalent and ionic bonds. give one example of each
Answer:
Actually, a covalent bond is formed between two non-metals. Electrons are shared between the two atoms in order for them to achieve a full outer shell. Covalent compounds do not conduct electricity. An ionic bond is formed between a mental and a non-metal. Electrons are transferred from the metal atoms to the non-mental atoms to form ions. Ionic compounds conduct electricity when dissolved.
Once bacteria have fixed nitrogen, it can be taken up by plants and animals, where it is used in the production of
energy and food.
mark me brainliestttt :))
Once bacteria have fixed nitrogen, it can be taken up by plants and animals, where it is used in the production of chlorophyll, amino acids, nucleic acids, and ATP.
Nitrogen serves several important functions in plants:
It is an important element in the synthesis of chlorophyll in plants. The chlorophyll itself is important for trapping the energy from the sun during photosynthesis.Nitrogen is a major component of amino acids which themselves are the building blocks of proteins. Proteins are important functional and structural biomolecules in all living organisms.Nitrogen is an integral component of nucleic acids which are essential for the storage of information, protein synthesis, and overall function of plants and animals.The element is also an important component of ATP, the energy currency of living organisms.Hence, once nitrogen is taken up by plants and animals, it is utilized in the biosynthesis of important structural and functional molecules such as ATP, chlorophyll, nucleic, and amino acids.

Explanation:
The best definition of technology is the practice applications of the scientific knowledge. The correct option is D.
What is Technology?Technology involves the practical use of scientific knowledge to create tools, machines, and systems that improve our lives and solve problems. It is not limited to just electronic devices, but encompasses a wide range of fields including engineering, medicine, and agriculture.
Technology is the means through which we put scientific knowledge to use. It encompasses both tools (like computers) and methods (like how we make computer chips), as well as both. Although the majority of contemporary technology is electronic, this does not mean that all technology is.
While the pursuit of scientific knowledge is important, it is the application of that knowledge that defines technology.
Therefore, the correct option is D.
