Explanation:
Whenever any clinical trail is conducted then the complete process is kept unbaised. Double blind testing can be defined as an experiment in which neither the researcher nor the person who is getting placebo and who is getting treatment knows. This is done in the clinical trials to keep the whole process unbaised.

The pros to climate change would include anything positive. Soooo
1. Fewer winter deaths
2. Low energy costs
3. Better agricultural yields
4. Fewer droughts.
Here is your conclusion.
Climate change may have a couple of pros but overall it’s terrible and we don’t want it to happen. It’s dangerous and could end the world. We need to take care of our earth and it’s as simple as not littering. Climate change is bad and just about every living thing would go extinct. Aka animals and humans.

Which of the following statements best describes the behavior of DNA during electrophoresis?
Longer DNA fragments migrate farther than shorter fragments
Migration distance is inversely proportional to the fragment size,
ОО
Uncut DNA migrates farther than DNA cut with restriction enzymes
O Positively charged DNA migrates more rapidly than negatively charged DNA.
Answers
Answer:
Migration distance is inversely proportional to the fragment size,
Explanation:
Gel electrophoresis is a technique used in molecular biology that uses electricity to separate biological molecules based on size (DNA) or charge (proteins). For the DNA molecule, different sizes are separated from one another based on how fast they can migrate through the gel matrix.
In this technique, small fragments or sizes of DNA migrates farther than long sizes of DNA due to low friction in the matrix. In other words, the smaller the size of the DNA fragment, the farther the migration distance and vice versa. This shows that an INVERSE RELATIONSHIP exists between the migration distance and the fragment size in the electrophoresis procedure.
Which is true about the DNA Molecule?
A.
It is made of many small parts that are separated by proteins.
B.
It is used as a way to defend against intense radiation.
C.
It is an incredibly long molecule with thousands of genes.

What would best describe the structure of the plasma membrane?
1.rigid (not flexible)
2.gaseous
3.solid
4.fluid (flexible)
Answers
Answer:
4. Fluid (Flexible)
Explanation:
Plasma membranes must be very flexible in order to allow certain cells, such as red blood cells and white blood cells, to change shape as they pass through narrow capillaries. The primary function of the plasma membrane is to protect the cell from its surroundings. Composed of a phospholipid bilayer with embedded proteins, the plasma membrane is selectively permeable to ions and organic molecules and regulates the movement of substances in and out of cells.
Describe how positive control in prokaryotes can be altered by the external environment
Answers
Answer:
The positive control is control when there is an activator present which acts as a regulatory protein so the operon and activator binds and initiates the stimulation of transcription to express the gene. In absence of this activator or regulatory protein, the operon will be inactivated.
External environmental stimuli can lead to alteration of the positive control in prokaryotes such as excess lactose in the environment. These environmental stimuli can induce transcription in prokaryotes.
In this example, if glucose is not available in the environment, the transcription of the lac operon will be induced by the presence of lactose in the environment.
What cell parts are common to What cell parts are found only in plant cells? What are found only in animal cells?
all of these cells?
Answers
Answer:
The organelles found only in plant cells include- chloroplast, cell wall, plastids, and a large central vacuole. The chloroplasts contain a green pigment chlorophyll that is responsible for the process of photosynthesis. What is the composition of a plant cell wall? The cell wall of a plant is made up of cellulose
Animal cells are eukaryotic cells or cells with a membrane-bound nucleus. Unlike prokaryotic cells, DNA in animal cells is housed within the nucleus. In addition to having a nucleus, animal cells also contain other membrane-bound organelles, or tiny cellular structures, that carry out specific functions necessary for normal cellular operation
Answer: the plant cell has a cell wall, chloroplasts, plastids, and central vacuole structures not found in animal cells. Plant cells do not have lysosomes or centrosomes.
Do all living things obtain the matter and energy they need to live and grow in the same way?
Answers
Answer:
Explanation:
This means all living organisms must obtain and use energy to live. Energy is the power to do things. ... A living organism can either make its food or depend on others to make food for them. For example, green plants produce their food from a process called photosynthesis.
Living things obtain energy and food to grow but different organisms do in different ways plants depend on the sun for photosynthesis.
How do living things obtain energy?Every living thing has a unique method of getting nutrients. Protozoans and other animals are among the creatures that obtain nutrition by eating food. Through the process of photosynthesis, plants and algae produce their own sustenance.
Animals consume food and drink to get the substance and energy they require for their biological activities.
A producer is an organism that produces its own nourishment. Sugars, a source of both energy and substance, are produced by plants using the energy from sunshine.
Therefore Plants are one type of creature that can produce its own food, to obtain energy.

Answer:
Water, Sunlight, Soil, and Air
Explanation:
Abiotic factors are the non-living components of an ecosystem. These are physical factors, such as water, sunlight, soil, and air.
In contrast, biotic factors are the living components and include birds and plants.
The way the biotic and abiotic factors interact with one another forms the ecosystem. The biotic factors rely on the abiotic factors to sustain their life.

Answers
Hi there!
Photosynthesis involves carbon dioxide (CO2) and water (H2O) as the reactants with glucose (C6H12O6) and oxygen (O2) as the products. We can write a basic chemical equation:
[tex]CO_{2} + H_{2} O - (light) -> C_{6} H_{12} O_{6} + O_{2}[/tex]
The equation has to be balanced, so the final equation for photosynthesis would be:
[tex]6CO_{2} + 6H_{2} O - (light) -> C_{6} H_{12} O_{6} + 6O_{2}[/tex]
The chemicals in correct order are:
[tex]CO_{2}\\H_{2}O\\ C_{6}H_{12}O_{6}\\ O_{2}[/tex]
A group of students wanted to know if millipedes prefer moist or dry environments. They suspected that millipedes would prefer moist environments because they had observed that millipedes are usually found under decaying logs.
Answers
Answer:
The suspicion of the students are very correct. Millipedes prefer damp environments. They need water moisture to survive.
Explanation:
Millipedes are known as arthropods. An Arthropod is an animal without a spinal vertebra, which possesses a segmented body, paired jointed appendages, and an exoskeleton.
They are found to be very ardent and quicker at recycling natural waste than animals and plants.
Without adequate moisture, Millipedes can die within 48 hours.

What other factors did you modify for BEE? Why do you think you need to consider these factors with caloric intake?
Answers
Answer:
The activity factor was modified. Ambulating indicates that the person is active. Even small activities require energy. So, people who can walk around and aren’t bedridden expend more calories than people who need to be on bedrest all day. Also, when the stress factor was changed to severe infection, the caloric requirement increased. This increase is probably because the immune system requires more energy to fight off the infection

The answer to this question is option C or "the leaves." The major site of photosynthesis in a plant is where the chloroplasts are located because it contains chlorophyll which is where photosynthesis takes place, chloroplasts is in all the green parts of a plant stem, leaves, and even the branches but it takes place mainly in the leaves of a plant because there is more leaves then roots or branches.
