Which statement illustrates bias in scientific research?(1 point)
A. A microbiologist publishes data funded by the National Institutes of Health that does not support their original hypothesis.
B. A botanist publishes data about plant growth that does not support their original hypothesis and is replicable.
C. An ecologist publishes data funded by a construction company which supports their original hypothesis that an endangered animal's territory is not endangered.
D. A zoologist publishes incomplete data on sloths which supports their original hypothesis and notes that more research is required.
Answer:
D
Explanation:
The statement that illustrates bias in scientific research is an ecologist publishes data funded by a construction company that supports their original hypothesis that endangered animal's territory is not endangered (option C)
In scientific research, bias can occur when the results or processes are manipulated on purpose. This usually occurs if:
The researcher wants the hypothesis to match the resultsThe researcher or sponsor has an economic interestScientific research occurs in situation B because it is convenient for the construction company to show that endangered animal's territory is not endangered as this would allow the company to build in certain areas and therefore, they are likely to manipulate the results of this research.
According to this, option B shows scientific bias. On the other hand, other options do not show bias because in these the results do not seem to be manipulated.

WBC's that produces a non-specific inflammatory response?
Answer:
inflammatory cytokines
Explanation:
In host cellular defense systems, non-specific immune responses are integral. It is a general white blood cell-mediated reaction where cells respond quickly to pathogenic infiltration.
Here, receptors on cells detect or even respond to signals from damaged, injured or stressed cells- these signals, such as inflammatory cytokines in a cytokine storm of molecules, in response to signatures shared by a wide range of pathogens.

Explanation:
hoped this helped :)
The characteristics that protists and fungi both have that make them eukaryotes is the possession of a membrane bound nucleus and other organelles.
EUKARYOTES:
Eukaryotic cells are cells that possess a membrane-bound nucleus to house their genetic material (DNA). Eukaryotes also possess other membrane bound organelles like mitochondria, golgi apparatus etc. This feature particularly differentiates them from prokaryotic cells. Eukaryotic organisms include plants, animals, fungi, some protists etc. Therefore, it can be said that the possession of a membrane bound nucleus and other organelles is the characteristics that makes fungi and protists be considered eukaryotes.Learn more: https://brainly.com/question/21196976?referrer=searchResults
which of the following is not a difference between DNA and RNA ?
Group of answer choices
they have different phosphate groups in their backbones
They have different sugars in their backbones
DNA is a double strand and RNA is a single strand
RNA replaces thymine with uricel
Answer:
I believe the answer is:
They both have different phosphate groups in their backbones
Option A is correct. DNA and RNA have the same phosphate groups in their backbones.
DNA is deoxyribonucleic acid. DNA contains deoxyribose sugar. DNA is usually found in double strands. In DNA thymine is present.
RNA is ribonucleic acid. RNA contains ribose sugar. RNA is usually found in single strands. In RNA thymine is replaced by Uracil.
Nucleic acid is made up of phosphate group, ribose sugar, and nitrogenous bases.
Hence, options B, C, and D are incorrect.

which series lists the structural components of the light-dependents reactions in order, from smallest to largest
Answer:
Chlorophyll >thylakoid> grana >chloroplast.
Explanation:
a cell is placed in solution which has the same solute concentration as the inside of the cell isotonic. because the concentration is the same on both sides of the membrane which direction will the water move via osmosis
Answer:
If a cell is in a medium with the same concentration of solutes with respect to intracellular space —isotonic— there will be no movement of water because there is no osmotic gradient or osmosis.
Explanation:
Osmosis implies the passage of water through a semi-permeable membrane from a place with a lower concentration of solutes to one where the concentration of solutes is higher. This difference in solutes concentration on both sides of the membrane produces an osmotic gradient, where the water will move towards the space with the highest concentration of solutes.
If a cell is in an isotonic medium —the same concentration of solutes inside and outside the cell— there is an equilibrium and the osmotic gradient is non-existent, so there is no movement of water or osmosis.
What is the function of the valves in the lymphatic vessels?
Answer:
1. pick up any fluid that has escaped the blood vessels
2. return the escaped fluid to the heart
3. remove any foreign material from the lymph
Explanation:
Lymph vessels pick up any fluid that has escaped the blood vessels and return it to the heart. Lymph nodes remove any foreign material from the lymph (bacteria, viruses, tumors) and contain lymphocytes (WBC!!!)
Each and every fluid that had already exited the blood arteries is collected by lymphatic vessels as well as returned towards the heart. Lymph nodules filter out foreign particles from either the lymph as well as house lymphocytes.

Sugars
Which of the following is true about the Calvin cycle?
Rubisco fixes O2 to a carbohydrate molecule.
Both ATP and NADPH are needed to make sugars.
Light energy is converted to chemical energy.
Answer:
1. ATP - decrease
2.NADPH - decrease
3. sugars - decrease
And True- Both ATP and NADPH are needed to make sugars.
Explanation:
Photosynthesis is a form of biosynthesis that produces glucose from the reactants; it uses energy from sunlight, along with carbon dioxide and water. It happens in the chloroplast in two phases; the light-dependent and dark reactions. In the light reaction, solar energy stimulates photosystems, formed from pigments like chlorophylls.
Chlorophyll forms photosystems of proteins known as complex proteins (PS I & PSII). PS II absorbs and moves the reaction center with light energy.
H+, and oxygen, are formed from a water molecule as it's broken apart. From photosystem II, electrons are transferred to photosystem I. ATP is synthesized from ADP along with inorganic phosphate. To form NADPHH, H+ is added to NADPIf PS II no longer works, there will be less ATP, NADPH, (both used later on) and no sugars produced.
In the dark reaction, products of the light reaction are used to make sugars. Here, in the Calvin cycle, the enzyme, RuBisCO, catalyzes the fixation of CO2 with Ribulose 1,5-bisphosphate (RuBP).

What happens between the two monosaccharides once water is removed?
Answer:
Dehydration synthesis is a chemical reaction that takes smaller, simpler molecules and combines them to form larger, more complex molecules with the removal of one WATER molecule. So, two monosaccharide (glucose) molecules come together and make a disaccharide (maltose).
Explanation:
At the end of the Calvin cycle, what molecules have the energy that originally came from light?
Answer:
The Calvin cycle has two parts. First carbon dioxide is ''fixed''. Then ATP and NADPH from the light reactions provide energy to combine the fixed carbons to make sugar.
Explanation:
At the end of the Calvin cycle, ATP and NADPH are the molecules have the energy that originally came from light.
Calvin cycle reactions are referred to as light independent reactions, because they can take place in the dark, provided the products of the light reactions (ATP and NADPH) are provided.
Cells do not store large amounts of ATP and NADPH, so the Calvin cycle depends on these molecules being contributed again by light reactions.
In these reactions (each one of them catalyzed by a specific enzyme), ATP and NADPH are used up, the two final products of the transformation of light energy into chemical binding energy by the chloroplast.
The Calvin cycle uses energy-rich products of light reactions (ATP and NADPH) to incorporate three CO2 molecules (one at a time) into a three-carbon sugar phosphate.
The carbon atoms fixed in the form of sugar in the Calvin cycle eventually become the carbons of all the organic molecules present in plants, animals and almost any form of life.
Therefore, we can conclude that at the end of the Calvin cycle, ATP and NADPH are the molecules have the energy that originally came from light.

A scientist claims that he has protected animal test subjects from a newly mutated virus using an experimental vaccine.The experimental vaccine was injected into five animal test subjects. The scientist also injected a placebo vaccine into five other animal test subjects.One month later, all of the test subjects were exposed to the mutated virus. The subjects that received the vaccination showed no sign of the disease and blood tests confirmed the presence of antibodies against the disease, but the subjects given the placebo developed symptoms of this condition.Why did one group have a placebo injected before being exposed to the virus?A) They were part of the experimental groupB) They would be protected from the diseaseC) They would be exposed to a weaker form of the virusD) They were part of the control group
Answer:
The correct answer is option D. they were part of the control group.
Explanation:
A control group is a group of subjects different from the other test subject as they did not get the independent variable's effect on them and separated from the rest of the experiment. This group of subjects is used to rule out any other explanation of the effect of the independent variable.
In this experiment, subjects that received a placebo injection are the control group as they did not expose to the mutated virus and there are the presence of antibodies in the blood.
