Answer:
The correct answer is : addresses a gap in knowledge
Explanation:
A scientific question is an inquiry or question that may prompt a hypothesis and help us in explaining or the answering the reason behind the question by observation. A hypothesis is a speculative, testable response to a scientific question.
A proper scientific question has certain qualities.
It should be answerable but not in ye or no,
It should lead to testable hypothesis
prompts a speculation that is falsifiable
should focus on only the one aspect that is asked
Thus, the correct answer is : addresses a gap in knowledge

Explanation:
Sirius A is 8.6 light-years from Earth. What is this distance in Kilometers?
Answer: 81,362,880,000,000 kilometres
Explanation:
A Light year refers to the distance that light travels in a year.
Light travels at a rate of 300,000 km/s.
This means that in a year it travels;
= 300,000 * 60 seconds * 60 minutes * 24 hours * 365 days
= 9,460,800,000,000 km in a year
Sirius A is therefore;
= 9,460,800,000,000 * 8.6
= 81,362,880,000,000 kilometres from Earth.

Pelvic inflammatory disease commonly affects all of the following organs, except the:_________.
A) uterus.
B) ovaries.
C) urinary bladder.
D) fallopian tubes.
Answer:
C) urinary bladder
Explanation:
Pelvic inflammatory disease commonly affects all of the following organs, except the urinary bladder
Pelvic inflammatory disease commonly affects all of the following organs, except the urinary bladder. Option C is correct.
Pelvic inflammatory disease (PID) is an infection of the female reproductive organs. The most common cause of PID is a sexually transmitted infection (STI), such as chlamydia or gonorrhea. PID can also be caused by bacteria that normally live in the vagina.
The organs that are most commonly affected by PID are the uterus, fallopian tubes, and ovaries. The urinary bladder is not typically affected by PID.
Here are some of the symptoms of PID:

Which of the following are final destinations of proteins directed to the secretory pathway? ▼endoplasmic reticulum ▼mitochondria ▼the plasma membrane ▼the outside of the cell▼ the nucleus ▼the golgi apparatus ▼lysosomes A. TRUE B. FALSE
Answer:
False, the final destination is the outside of the cell
Explanation:
The secretory pathway moves proteins to the cell membrane, where they are released to the extracellular medium. In this pathway, the proteins enter into the membrane of the rough Endoplasmic Reticulum (ER) in a cotranslationally way (i.e., during their synthesis in ribosomes). This pathway can be summarized by the following transporter activities: Endoplasmic Reticulum >> Golgi apparatus >> secretory vesicles (such as lysosomes) >> cell membrane, where proteins are finally released by exocytosis.
Explain the difference between repetition and replication. plz
Answer:
Repetition: Doing something over and over/doing something repeatedly
Replication: Duplicating something/duplicating yourself
Explanation:
I hope this helps :)
Answer:
Repetition refers to performing multiple trials throughout an experiment.
Repetition reduces mistakes and increases one’s confidence in the results.
Replication refers to the ability of a process to be repeated by another individual.
When a scientist replicates another’s experiment, the experiment should produce the same results.

Questions:
1. How is a cell membrane like the plastic bag in the experiment?
2. Define diffusion.
3. List two reasons why molecules will not diffuse into cells.
Explanation:
1. cell membranes are partialy permeable, only allowing passage to some certain molecules.
2. diffusion is the movement of molecules across partially permeable membrane down concentration gradient.
3. the molecules are too big to pass through partially permeable membrane. the concentration of the molecule might be higher in the cell than in the solution/surroundings.

Which of the following statements about eukaryotes is not true?A) They contain organelles like mitochondria, chloroplasts, the endoplasmic reticulum and the nucleus.B) They are usually 10 to 100 microns in diameter.C) They can be either unicellular or multicellular.D) They are also called archaea.E) All of the above are true of eukaryotes.
Answer: Option B, D and E.
They are usually 10 to 100 microns in diameter.
They are also called archaea.
All of the above are true of eukaryotes.
Explanation:
Eukaryotes are organisms that have nucleus and it is surrounded by nuclear envelope and membrane bound organelles in the cell cytoplasm.
They can either be unicellular or multicellular compared to prokaryotes that are Majorly unicellular.
They are not usually 10 to 100 microns because most eukaryotes are multicellular organisms and they are bigger in sizes visible to the eyes like fish, goat,humans.
Eukaryotes are not usually archaea because archaea is are Majorly prokaryotic organisms that are unicellular and have no nucleus.
The diagram is a model of the structure of glucose. The structural formula of glucose, C6H1206, shows a ring of 5 carbon atoms and 1 oxygen atom. 4 carbons in the ring are each bonded to an -H and an -OH group in addition to 2 neighboring atoms in the ring. The fifth carbon is bonded to a CH2OH group. What structural feature does glucose share with larger carbohydrates? A. a ratio of 1 carbon atom to 2 hydrogen atoms to 1 oxygen atom B. the presence of double covalent bonds between carbon atoms C. strong bonds between carbon atoms that cannot be broken D. ionic bonds between carbon atoms and oxygen atoms
Answer:
The correct answer is : A. a ratio of 1 carbon atom to 2 hydrogen atoms to 1 oxygen atom
Explanation:
Carbohydrates are the primary and major component of diet, these molecules give vitality to the body, predominantly by means of glucose, a fundamental sugar, which is an part of the starch and a fixing in different staple nourishment diet choices.
the significant chemical formula of carbohydrates is (CH2O)n. It can be exhibited or express by the proportion of the carbon to hydrogen to oxygen which is 1: 2: 1 in the particles of starches. Starches are additionally arranged into three sub-sorts, that is, monosaccharides, disaccharides, and polysaccharides. The monosaccharides are the basic sugars, for instance, glucose.
Thus, the correct answer is : A. a ratio of 1 carbon atom to 2 hydrogen atoms to 1 oxygen atom

Why do you think invasive species are more of a problem in human altered biomes (anthromes) than they are in a biome that has not been altered by human activities?
Answer:
invasive species are a problem both in anthropogenically altered and natural environments
Explanation:
An invasive species can be defined as a non-native species introduced into a new environment which then becomes abundant. Only in the US, it is believed that there are approximately 4,000 invasive species (some examples include the feral pigs, grey squirrels, European rabbits, etc.). In general, invasive species have a negative impact on the ecosystem, especially by displacing native species and thereby altering the trophic chain. In anthropogenically altered environments (anthromes), human beings are considered to be an invasive species.
why might the nucleus be referred to as the brain of the cell
