Design your own scenario related to Bacteria or Viruses. Identify the independent and dependent variables.
Answer:
An experiment where an antibiotic is tested against bacteria. The antibiotic can vary in its concentration for example, different amounts are applied to a sample of bacteria to see if it is affected by the action of the antibiotic and if so, in what concentration. So, the independent variable is the concentration of antibiotic while the dependent variable is the survival (or not) of the bacteria.
Explanation:
An independent variable is a variable that represents a quantity that the scientist modifies in an experiment. A dependent variable represents a quantity whose value depends on how the independent variable is modified. This is the variable being studied and measured.
So, an example of this applied to bacteria or viruses could be:
An experiment where an antibiotic is tested against bacteria. The antibiotic can vary in its concentration, different amounts are applied to a sample of bacteria to see if it is affected by the action of the antibiotic and if so, in what concentration. So, the independent variable is the concentration of antibiotic while the dependent variable is the survival (or not) of the bacteria.
To complete the experiment, an antibiotic whose effect is already known can be used as a positive control. That is, it is already known to kill the bacteria. And as a negative control you can simply use water, which has no effect and is known not to kill the bacteria. In this way, we validate the results and make sure that there is not something else that is affecting the bacteria and that only the antibiotic being studied has an influence.

Answer:
Explanation:
Transpiration can be regarded as process involving water movement through a plant, it involves evaporation from aerial parts. These aerial part could be such leaves, stems or flowers.
A)Temperature
During the day period when the weather is hot there would be increase in evaporation of water from the leaves of plants, due to this transpiration is increased
B)Light intensity
When there is bright light, when the light intensity heat the plants, the stomata would be opened so that carbon dioxide is supplied for photosynthesis, and more water would be evaporated out through the leaves of the plant, then transpiration increase

What happens to the effenciency of the exchange of oxygen in the human body at a high altitude
Answer:
The effiency decreases at higher altitudes
Explanation:
The higher up a person is on a mountain, the thinner the air is due to the lack of plants that can grow. An example of this is Mount Everest. At a certian point on the mountain, called the "Death Zone", the air is too thin to supply enough oxygen to the human body to survive. That's why they bring oxygen tanks with them on their adventures.

1. Describe what occurs in the body of a type 1 diabetic after they consume a carbohydrate-heavy meal. In your response, include the following terms
Metabolized, Glucose, Insulin, Cell receptors, Pancreas, Energy
The process which would occur in the body of a type 1 diabetic after they consume a carbohydrate-heavy meal is:
The digestive system tries to break down the complex sugars which increases the blood sugar level which leads to the production of insulin to maintain the blood sugar level throughout the body.A Type 1 diabetic person is one who has been diagnosed with the level of diabetes, where the pancreas does not produce enough insulin to control the sugar levels of the body.
With this in mind, when such person consumes a high carbohydrate meal, it means that he has ingested complex sugars which would be difficult for the digestive system to break down which would overwork the pancreas, but as there is little or no insulin production, then there would likely be health complications.

A. Convection currents in magma drive plate tectonics.
B.Convection currents in magma are a result of density differences.
C. Convection currents play a role in the movement of Earth’s inner core.
D. Convection currents in magma are caused by temperature differences.
Answer: C....Convection currents play a role in the movement of Earth’s inner core
The statement which is not correct with regard to convection currents is as follows:
Convection currents play a role in the movement of Earth’s inner core.Thus, the correct option for this question is C.
What is Convection current?Convection current may be defined as a procedure that significantly involves the movement of energy from one place to another. It is basically the existence of current in a fluid through convection.
The inner core of the earth has appeared as solid as compared to other parts like the crust and mantle. Most liquid particles are definitely found on the mantle of the earth's surface.
Due to the presence of excessive liquid particles and compounds, the convection current is significantly noticed there.
Apart from this, magma is also a fluid that derives current through convection. It produces in a number of ways like magma driving plate tectonics, density differences in the magma, and temperature differences.
Convection currents are basically the movement of fluid with respect to temperature or density difference within the material.
Therefore, the correct option for this question is C.

Question 1/7 The Nile River carries sediments to the ocean. Over time, the sediments are compressed as more sediments are deposited on top of them. Which type of rock will be formed?
Answer:
Sedimentary Rock
Explanation:
Sedimentary rocks are formed from pieces of sediments or other existing organic matter or rock.
The sedimentary rock formation process begins with weathering which involves the breakdown of the sediments into small fragments. The next process is erosion, where water like the Nile River carries them to other places - in this case, the Ocean.
Over time, the sediments settle and become compressed as more sediments are deposited on top of them.
This leads to the formation of Sedimentary Rocks.

What is chromosome ?
A chromosome is a thread-like structure present in the nucleus of cells such as both prokaryotic and eukaryotic cell and it is made of a molecule of DNA (Deoxyribonucleic acid) and histone proteins.
It is composed of three components, DNA, proteins and RNA, amount of the DNA content ranges from 30 to 40 %, the amount of proteins from 50 to 65%, and small amount of RNA from 1 to 10%.
Two types of protein present in DNA such as histone and non-histones proteins, histone constitute large amount (90% of total protein), whereas non-histone is present in small amount (around 10% of total protein).
The histone protein is basic, whereas, the DNA is acidic, so it can be neutralized; DNA in chromosome is present in two forms such as Euchromatin and Heterochromatin.

What are protists?
Protists are single-celled microorganisms that belong to the kingdom Protista. They are unicellular organisms that are not classified as bacteria, fungi, or animals, and are the simplest of the eukaryotes (organisms with a true nucleus and other membrane-bound organelles). Protists are found in a wide variety of habitats, from freshwater to marine environments, and are important for their role in the food chain, as well as for their impact on human health.
Protists come in a wide range of shapes and sizes, from amoeba-like organisms that can change shape, to algae with chloroplasts, to parasites that can cause diseases in humans and other animals. Some protists can move on their own, while others are immobile. Some can reproduce asexually, while others reproduce sexually. Despite their diverse forms and functions, all protists are considered to be part of the same kingdom because of their shared characteristics and evolutionary relationships.
