Answers
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.

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?
Answers
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.

Sirius A is 8.6 light-years from Earth. What is this distance in Kilometers?
Answers
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.

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
Answers
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.

Answers

No, exercising something you enjoy does not affect a student's grade, if it is controlled.
Explanation:
Playing a couple of hours a day (1-3 MAX) will not affect a student's grade, but excessive playing will affect their grade negatively, as the video game will stay on their mind unconciously (most of the time) which will distract the student and prevents the student from thinking straight, regarding the fact that it could cause eye damage, and increases the chances of epilepsy.

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
Answers
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
