8) A _____ has a nucleus, a corona, and a tail.
meteors
comet
stars
planet
asteroid
Answer:
I'm pretty sure it's a comet!
Explanation:
A comet's nucleus is like a snowball made of ice. As the comet nears the Sun, the ice starts to melt off, along with particles of dust. These particles and gases make a cloud around the nucleus, called a coma. A comet's nucleus, or heart, is the solid chunk of something in the center of its fuzzy coma.
Most comets have two tails. ... Because the comet dust particles are so small, they are pushed away from the Sun into a long tail. Another tail is made of electrically charged molecules of gas (called ions). Very rarely a comet will have a third tail made of sodium, which we usually don't see with our unaided eyes.

Drinking alcoholic or caffeinated beverages increases urine output more than drinking an equivalent amount of water.
RequireD:
a. How do you think these beverages affect ADH secretion?
b. Would urine osmolarity be increased or decreased?
Answer:
A) ADH secretion decreases. B) Urine osmolarity decreases.
Explanation:
Antidiuretic Hormone or ADH is responsible for the reabsorption of water through the kidneys.
A) Drinking alcoholic and/or caffeinated beverages decreases the release and effect of ADH so the water does not get absorbed as much as it should, which in turn results in more urination.
B) Osmolarity is a term used to express the concentration of a solution in terms of a certain particle. Since less ADH secretion results in more water being in the urine, this lowers the concentration of the urine. So urine osmolarity would be decreased.
I hope this answer helps.

The natural role of restriction enzymes in bacteria is to make conjugation more efficient. allow transposons to move to another place in the chromosome. protect the cell from invading phages. allow cells to accept foreign DNA. provide the cell with new phenotypes, such as antibiotic resistance.
Answer:
protect the cell from invading phages
Explanation:
The natural role of the restriction enzymes is to protect the cell from invading phages.
The restriction enzyme is an enzyme that functions by cutting DNAs from some pre-identified sites on the DNA. They are primarily found in bacteria where they protect the cell from invasion by foreign DNA from phages.
Once a phage invades a bacterium, the restriction enzyme quickly acts by cutting the phage's DNA into smaller pieces, leading to the destruction of the DNA and hence, the protection of the bacterium cell.
What are the ordered pairs?
Answer:
Ordered pairs are 2 numbers that show where a specific point is on a gird
Example:
(3,2)

According to MacArthur and Wilson's theory of island biogeography, both the land area of an island and the _____________________ contribute to species diversity
Answer:
According to MacArthur and Wilson's theory of island biogeography, both the land area of an island and the distance from the mainland or continent contribute to species diversity
Explanation:
The ecologists MacArthur and Wilson took the term island biogeography theory to refer to the predictions about the number of species that could be inhabiting on an island.
Island biogeography theory establishes that the two factors that affect species richness in natural communities on an island are the distance from the mainland and the size of the island.
At the same time, these factors affect inmigration and extinction rates. According to the theory, islands that are closer to the continent have higher possibilities of receiving immigrants than those islands that are located farther from the mainland. This is the effect of distance.
The effect of size is reflected in the relation between island size and species diversity. In smaller islands, the probability of extinction is higher than in bigger islands. Bigger islands can have more species than smaller ones.
In the case of two islands of the same size and different distance to the mainland, both of them will have the same extinction rate, but the one closer to the continent will have a higher immigration rate, and so, a higher amount of species. The S value will be higher on the island closer to the continent.
A student wants to test the hypothesis that plants need soil to grow. Identify the independent
and dependent variables for this experiment, and three variables the student should control
during the experiment.
Answer:
Independent variable: Adding/not adding soil.
Dependent variables: Does the plant grow? Amount of leaves, plant length.
Controlled variables: Type of plant used, amount of sunlight received, pot used for plant, amount of water given, temperature of soil, etc.
Explanation:
Independent variable: The thing that you want to change. To see if plants need soil to grow, you would need to either add or remove soil altogether.
Dependent variables: The thing that is being measured. By adding your independent variable, you should be able to answer certain questions.
Controlled variables: Things you want to keep the same for each experimental group. For example, if you used different plants, your results could be affected negatively as some plants might rely on soil less than others/grow at a slower or faster pace.

A population of birds colonizes an area in which the insects upon which they feed live inside trees. Which of the following events accounts for an observed increase in average beak size in the bird population over time?
a. Decreased fitness of the insects, allowing the birds to catch them more easily
b. Increased fitness of large-beaked birds, leading to natural selection
c. Increased fitness of the large-beaked birds, creating a new species
d. Decreased fitness of small-beaked birds, creating a new species
Increased fitness of large-beaked birds, leading to natural selection. So, the correct option is (B).
What is Natural Selection?Natural selection is defined as the differential survival and reproduction of individuals due to differences in phenotype which is a major mechanism of evolution, a change in the genetic properties of populations over generations.
For Darwin, natural selection is a drawn-out, complex process involving many interrelated causes where it requires variation in populations of organisms. For the process to work, at least some of that variation must be heritable and passed on to the organism's descendants in some way.
Example of Natural selection is birds with larger beaks are better able to survive in the new environment.
Thus, increased fitness of large-beaked birds, leading to natural selection. So, the correct option is (B).

Which of the following most directly influences a measurable outcome in an experiment. An independent variable A variable hypothesis A dependent variable Previous information
Answer:
An independent variable
Explanation:
An experiment consists of two variables viz: independent and dependent variable. Independent variable is the variable that the experimenter controls in order to influence or effect a change in the measurable variable called dependent variable. As the name suggests, the dependent variable is dependent on the independent variable.
For example, a scientist is trying to conduct an experiment on how the caffeine level in different types of drink affects the time of sleep in individuals. The independent variable in this experiment is the TYPE OF DRINKS because it is the variable controlled by the experimenter in order to influence the time of sleep (measurable outcome).

You watch a scientist dissolve some sugar in a liter of water and then place some of this
solution into a dialysis bag, tying both ends shut. The she places the bag into a beaker of
distilled water. What word best describes the solution outside of the bag?
Answer:
Hypotonic
Explanation:
The tonicity of a solution describes its solute composition and its ability to exert osmotic pressure on a membrane. A solution can attain three tonicity states viz: hypotonic, hypertonic and isotonic.
A solution is said to be HYPOTONIC if its solute concentration is lesser than that of its surrounding environment. In other words, the concentration of solute in the solution is lower in comparison to another. This is the case of the solution outside the dialysis bag.
The solution inside the dialysis bag contains more concentration of solute because of the sugar placed in it. The solution outside the bag contains distilled water with no solute, hence, it is HYPOTONIC to the solution inside the bag.
