Answer:
What are the three basic parts of the cell theory?
Cells are the basic units of composition for living things.All living things are composed of cells.All cells come from pre-existing cells.Carbon dioxide is A a toxic gas produced by landfills. B produced by plants during photosynthesis. C needed by industry to power generators. D a greenhouse gas that traps heat in the atmosphere.
Answer:
The correct answer is option D, that is, a greenhouse gas that traps heat in the atmosphere.
Explanation:
A natural phenomenon in which the atmospheric gases captivates heat and permits Earth to retain enough solar energy to be livable is termed as the greenhouse effect. The greenhouse gases are the methane, carbon dioxide, nitrous oxide, and other gases, which gathers in the atmosphere and produces a heat-reflective layer that helps in trapping sunlight and keeps the Earth warm.
Of these greenhouse gases, carbon dioxide is the largest contributor to climate change. It is largely emitted at the time of burning fossil fuels like natural gas, oil, and other carbon-rich sources. Due to this, the level of carbon dioxide increases in the atmosphere resulting in the global phenomenon termed global warming.

Which of the following sustainable farming practices allows farmers to rely on their own water supply, rather than bringing in water from different locations? using wells crop rotation drip irrigation using insecticide
Answer:
drip irrigation
Explanation:
The correct answer would be drip irrigation.
It is a small scale irrigation system that is usually set up to minimize water usage compared to other forms of irrigations. The system consists of different pipes that start from the water source and networks to the stands of plants. Control valves also exist and these ensure that water slowly drips directly to the root of plants. The drip could be either from the above or below the ground surface.
Due to the efficiency associated with dripping water directly to the root of plants which is where it is primarily needed, the drip irrigation system requires minimal water supply and is sustainable.

How did the “Father of Anatomy” contribute to the study of the human body?
Answer:
Andreas Vesalius became first to study human anatomy.
Explanation:
Andreas Vesalius wrote a book called Seven Chapters on the Structure of the Human Body that caused to the rise of advanced human anatomy. His work became very notable for medicine because it gave physicians a thorough knowledge of human anatomy, and it propelled them to examine the claims of ancient medical experts, which were unusual than Vesalius hypotheses. He's seen as a Renaissance figure of the 16th Century and considered being the father of modern medicine.

How is a Hypothesis different from a Theory?
Identify the type of growth response that each plant demonstrates. your options are Phototropism and Gravitropism
The purple and sunflower are phototropism and the big tree and the little tree upside down are gravitropism.
What do you mean by gravitropism and phototropism?
Roots, in general, bend away from light (i.e. negative phototropism) in the direction of gravity, whereas stem-like organs orient their growth toward light (i.e. positive phototropism) and away from gravity (i.e. negative gravitropism).
In given images, the purple and sunflower are phototropism and the big tree and the little tree upside down are gravitropism.

o the independent variable is the number of mosquito bites and the dependent variable is the
repellant
the independent variable is the repellant and the dependent variable is the 2 hour time
the independent variable is the repellant and the dependent variable is the number of mosquito
bites
Answer:
Dependent variable: Number of bug bites
Independent variable: Sprayed arm
Control group: Arm not sprayed.
Experimental group: Sprayed arm
Explanation:
If you know the definitions for the independent variable, dependent variable, control and experimental group in a problem than it would be less complicated to figure out what they are in any given example. So, here are the definitions:
Independent variable: the factor that you change
Dependent variable: the factor that is measured
Control group: the factor that is kept the same
Experimental group: the group in an experiment that receives the variable being tested

What part of the body reproduces, grows, repairs itself, uses oxygen and nutrients, digests food, eliminates waste, produces heat and energy, and is able to move around
Answer:
A Human Cell
Explanation:
A Human Cell can do many things. All your organs, hair, skin, and muscle tissue are all made up of cells. Each human cell from a different part of your body can do and create different things. For example, the cells duplicate (which is reproduction), when it duplicates, it grows. It also uses the oxygen and nutrients for cellular respiration, when it takes in the oxygen and nutrients, it turns it into ATP, which is used to help your cells function. There are many other ways the human cell may relate to the question above. But here are some of the ways a human cell can be all those things.
A toy car is placed at 0 on a number line. It moves 9 cm to the left, then 4 cm to the right, and then 6 cm to the left. What is the total distance the toy car traveled? 1 cm 5 cm 11 cm 19 cm
Answer:
19 cm
Explanation:
The total distance traveled by the toy cay would be 19 cm.
The total distance traveled should not be mistaken for total displacement. While displacement measures the distance and direction from the starting position of the toy car relative to its final position, the total distance traveled is calculated by adding all the movements of the toy car together. Hence;
Total distance traveled = 9 + 4 + 6 = 19 cm
The total distance the toy car traveled is 19cm
Distance measures how far a body or an object has moved no matter the direction has taken (either positive or negative)
For the toy car that is placed at 0 on a number line, the toy moved the following distance:
9 cm to the left4 cm to the right6 cm to the left.Total distance = Total distances to the left + total distance to the right
Total distance = 9cm + 6cm + 4cm
Total distance = 19cm
Hence the total distance the toy car traveled is 19cm

a. what process is occurring in the plant's cells to produce the gas in the bubbles that appear?
b. what gas is the plant producing?
c. what source of energy is the plant using to conduct the process recorded in part a?
Answer:
a. Photosynthesis
b. Oxygen
c. Light from the lamp
Explanation:
a. The process that is occurring in the plant's cell to produce the gas in the bubble is photosynthesis. The process involves the use of inorganic substances such as carbon dioxide and water in the presence of light to manufacture carbohydrates. Oxygen is evolved in the process. The equation for the process is as below:
[tex]6 CO_2 + 6 H_2O + light --> C_6H_1_2O_6 + 6 O_2[/tex]
b. The gas produced by the plant is oxygen as shown in the equation above.
c. The source of energy the plant is using to conduct the process is the light from the lamp. Light catalyzes the excitation of photosystems, causing the release of electrons that causes the splitting of water.

what would be the affect on pcr reaction, if primers are not added in the reaction?
Answer:
In absence of the primer the reaction lacks a primer template junction, and thus a free 3′-hydroxyl group will cause the reaction to fail.
Explanation:
In the PCR reactions primers are used to bind to ssDNA template hybridize itself and define the segment or part of the sample that will be amplified. This hybridize template makes the primer template junction.
If primers not added this junction would not be created then the enzyme DNA polymerase cannot make new DNA due to there is no free 3′-hydroxyl group which is essential to bind with the first deoxynucleotide.
Thus, In absence of the primer the reaction lacks a primer template junction, and thus a free 3′-hydroxyl group will cause the reaction to fail.
