Create a dichotomous key based on the characteristics of various fruits
1. Choose a group of five or more different fruits. It may be helpful to keep a picture of your group of fruits or the fruits
themselves together so that it is easier to make your key and identify the fruits that you are using
2. If you do not have the fruit on hand, look up a picture online or from any other suitable reference material.
3. Carefully examine or think about the characteristics of the fruits and create a dichotomous key using some of these
characteristics. The list provided in the experiment should give you an idea of some of the fruits and/or characteristics
that could be used, but you are free to use any of your own choosing

The picture above is an example of what type of tissue?
Answer: Epithelial Cell
Explanation:
The given picture above is an example of epithelial tissue. Option 3 is correct.
Epithelial tissue is a type of tissue that covers the outside of the body and lines the inside of organs and cavities. It is made up of tightly packed cells that form a continuous sheet. Epithelial tissue has many functions, including:
Protection: Epithelial tissue protects the body from harmful substances and pathogens.Secretion: Epithelial tissue secretes substances such as mucus, sweat, and tears.Absorption: Epithelial tissue absorbs nutrients and other substances from the environment.Excretion: Epithelial tissue excretes waste products from the body.There are four main types of epithelial tissue:
Simple squamous epithelium: This type of epithelium is made up of a single layer of flat cells. It is found in the lining of the blood vessels, lungs, and kidneys.
Simple cuboidal epithelium: This type of epithelium is made up of a single layer of cube-shaped cells. It is found in the lining of the kidney tubules and the small intestine.
Simple columnar epithelium: This type of epithelium is made up of a single layer of column-shaped cells. It is found in the lining of the stomach, intestines, and uterus.
Stratified squamous epithelium: This type of epithelium is made up of multiple layers of flat cells. It is found in the skin, the lining of the mouth, and the esophagus.

The drug given to the participants in Group A was the clinical trial drug.
After the manufacturing of a drug, the new drug needs to be evaluated before being pushed into the market for population use.
Researchers usually follow three main steps:
Preclinical drug trialsAnimal trials Human clinical trialsDuring the human clinical trials, drugs that have passed animal tests are used for human clinical trials.
This involves the use of two groups:
Group A: A pill containing a new drug known as the clinical trial drug will be given to participantsGroup B: A pill containing NO drug known as placebo will be given to the same number of participants.The results obtained from both grouped would be evaluated. This will give the manufacturer a clear view concerning the new drug, if it is safe and effective in people.

Pablo and Johanna must complete a yearlong study for their biology course. After some discussion, they decide to compare dog diets. To test their hypothesis that the local veterinarian's special dog food mix will enhance growth and development, each student adopts a puppy from the local pound. Pablo plans to feed his goldendoodle the special diet, while Johanna plans to use generic dry kibble from the supermarket for her bulldog. Pablo and Johanna have too many ________.
Pablo and Johanna have too many independent variables.
In order to conduct an experiment, 3 kinds of variables are used. These are:
Dependent variable Independent variable Control variableA dependent variable is a variable that the experiment seeks to observe and measure, this variable is expected to change in value throughout the experiment and depends on other variables. An independent variable is one that the researcher changes throughout the experiment in order to see what effect it will have on the dependent variable. Finally, the control variable is the variable that remains the same throughout the experiment in order to limit the influence they will have on the outcome. If the value we wish to measure changes, the presence of control variables helps to narrow down and correctly credit the cause of this change, leading to a valid experiment.
In the situation given, Pablo and Johanna have too many independent variables. The dependent variables that Pablo and Johanna wish to measure are dog growth and development. The independent variable is the one they change in order to see what effect it will have on the dependent variable, in this case, the dog food. However, the experiment would not be valid because the breed of dog should be a control variable to ensure correct data, given that different breeds of dogs grow and develop at varying rates. This variable is instead an independent variable in this given experiment, given that it changes between the two groups and will affect the outcome.

How would cellular respiration be impacted in the absence of photosynthesis?
Only aerobic respiration would take place.
Only anaerobic respiration would take place.
Fewer ATP would be produced during cellular respiration.
Both reactants of cellular respiration would not be available.
Answer:
I believe it is D. Both reactants of cellular respiration would not be available
Explanation:
I do FLVS too im on the test rn :D
it was correct.
photosynthesis and cellular respiration work together to create the life cycle. without Cellular respiration we would die and without photosynthesis we would die. They are equally important without one the other could not function
have a great day
:)
Only anaerobic respiration would take place in the absence of photosynthesis, hence option B is correct.
What is the relation between cellular respiration and photosynthesis?Oxygen and glucose are used in cellular respiration to create carbon dioxide and water. The equation for photosynthesis is the inverse of the equation for cellular respiration, further emphasizing this concept.
The cycle of cellular respiration and photosynthesis is essential for the survival of humans, animals, and plants. The term "cellular respiration" describes a chain of metabolic processes that convert glucose into water and carbon dioxide and ATP.
Therefore, in the absence of photosynthesis, there would be no glucose or oxygen for respiration, and since photosynthesis requires carbon dioxide, only anaerobic respiration would be possible.

List the abiotic and the biotic factors in the following image.
The factors considered as living are biotic factors and includes trees, scorpion, bug, and plants, whereas non-living things like snow, cloud, ice, wind, ice flakes, etc., are abiotic factors.
What are abiotic and biotic factors?Organic and living things have various characteristics that include organic matter, plants, microorganisms, and animals. The scorpion, bug, trees, cactus, etc., are biotic factors that show the properties of living things.
The abiotic factor is said to be non-living things that do not show any property of the living beings and includes climate, sun, soil, and temperature. Clouds, snow, flakes, ice cubes, etc. are examples of abiotic factors.
Therefore, biotic and abiotic factors together make the ecosystem.

What evidence contradicts the theory that moving two-ton stones was physically impossible for the Egyptians, and must have been done using alien technology?
Answer:
Archaeological evidence shows that Egyptians worked together to build the pyramids. Remains of quarries and ancient tools suggest that large slabs were created from rock beds. The slabs were placed on sleds and pulled to the building site. To make this process easier, men most likely poured oil on the roadway. This process is depicted in tomb paintings that date back to 1900 BCE.
