which organelles are needed to bring in or move out materials from the cell
Answer:
Molecules can diffuse across membranes via transport proteins, or they can be aided in active transport by other proteins. Organelles such as the endoplasmic reticulum, Golgi apparatus, mitochondria and peroxisomes all play a role in membrane transport.
A researcher analyzes the interaction between two investigational drugs. He begins by plotting the dose–response curve for the first drug, administered alone. He then administers both drugs in combination and plots a second dose–response curve. When the two drugs are co-administered, the dose–response curve is shifted significantly to the right. He concludes, therefore, that the interaction between the two drugs is:__________
Answer: antagonistic
Explanation:
A researcher analyzes the interaction between two investigational drugs. He begins by plotting the dose–response curve for the first drug, administered alone. He then administers both drugs in combination and plots a second dose–response curve. When the two drugs are co-administered, the dose–response curve is shifted significantly to the right. He concludes, therefore, that the interaction between the two drugs is antagonistic.
An antagonist is sometimes called blockers and it is simply referred to as a type of drug that avoids a biological reaction. An antagonist doesn't activate when it binds to the receptor but what it does is that it blocks the receptor. From the question, we are told that when the two drugs are co-administered, the dose–response curve is shifted significantly to the right, this implies that the interaction is antagonistic.

Sugars and amino acids are the important biomolecules which make the genetic material of an organism. These are made up of same elements except amino acids also contain nitrogen in them. Thus, the correct option is C.
What are biomolecules?Biomolecules are the organic compounds which are important for the survival of an organism. Sugars and amino acids are the two important classes of biomolecules which carry the genetic information in them.
Sugars are the carbohydrates which contain carbon, hydrogen, and oxygen elements. These include ribose sugar and deoxyribose sugar which are the components of genetic material- DNA and RNA.
Amino acids are the amphoteric acids which contain both carboxylic acid group and amino group in them. Amino acids combine to form protein molecules. Amino acids are made up of carbon, hydrogen, oxygen, and nitrogen elements.
Therefore, the correct option is C.

The correct answer is C. It is not degraded by most microorganisms and solid agar remains solid until the temperature is raised to 90°C, and liquid agar remains liquid if the temperature is lowered to 45°C are correct.
Explanation:
Agar is a substance derived from red algae mainly used as part of some foods and microbiology works. In microbiology, agar is an ideal substance due to its stability and low susceptibility to temperature. Indeed, agar will remain solid below 90° C and liquid below 45°.
Moreover, agar is used in microbiology because this substance cannot be degraded by most microorganisms. Due to this, it is commonly used as a culture medium that will preserve stable properties as it is not affected by the bacteria, and other organisms growing in it. According to this, the correct answer is C.

You are an almond grower and want to determine whether almond size (measured as shelled almond weight) is a heritable trait. A survey of 800 trees from several groves indicates that the average shelled almond weight is 5.71 g. You select the 40 trees producing the biggest almonds (average shelled almond weight of 6.48 g), then cross-pollinate the flowers from these trees. You plant the almonds produced by these flowers and when the resulting trees reach maturity, you measure the size of their almonds and find that the average shelled almond weight is 5.85 g.
1. Calculate the selection differential.
2. Calculate the response to selection.
3. Calculate heritability (h2).
4. If you were to carry out this breeding program for multiple generations would you expect to see almond production to be strongly influenced by genetics, environment, or a combination? Explain.
Answer: 1. S = 0.77
2. R = 0.14
Explanation:
1. Selection differential is the difference between the population mean and the average of the selected parents. Its symbol is S.
S = mean of selected parents - population mean
S = 6.48 - 5.71
S = 0.77
2. Response to Selection is how much gain you make when crossing over selected parents. Its symbol is R.
R = mean of offspring of selected parents - population mean
R = 5.85 - 5.71
R = 0.14
3. Heritability is, basically, a statistical variable that shows how much the variation in a trait is due to genetic factors. Its symbol is h².
To calculate it, use Breeder's Equation:
R = h²S
[tex]h^{2}=\frac{R}{S}[/tex]
[tex]h^{2}=\frac{0.14}{0.77}[/tex]
h² = 0.18
4. You would expect the production to be strongly influenced by environment, because heritability lies between 0 and 1. Low heritability means there is low level of resemblance between offspring and parents. As this program heritability is low, the resemblance is small, which means the characteristics are influenced mostly by the enviroment.
Which of these is more likely to have winter ice?
A)
lakes
B)
open ocean
C)
salt marsh
D)
mangrove forest
E)
estuary
Answer:
A. Lakes
Explanation:
Usually the open ocean has too much movement and higher temperatures to freeze over, so that excludes salt marches and estuary as well. Mangrove forests usually survive in salt water areas, which again the salt and movement of salt water allows for the water to not freeze over. With lakes, they are usually smaller bodies of water found all over the world, and can easily have the top freeze over, since there's no salt, not as much movement, and temperatures can vary more often.

Which description refers to cirrus clouds? are fluffy are wispy produce snow form at low altitudes
Answer:
Wispy is the answer :))

• These clouds are delicate, are wispy, look like tufts of hair and are silky sheen.
• They are whiter than any of the clouds during the daytime.
• With the rising or setting of the Sun, they make take the colors of the sunset.
• The cirrus clouds are formed completely of ice crystals that provides them the white color.
• They are formed from the ascent of dry air, which makes the small quantity of water vapor in the air to get deposit into ice.

b) Habita en los ríos
c) Es un parásito
d) Son pequeñas
e) Pertenece a los platelmintos
Answer:
The correct answer is option c) Es un parásito.
Explanation:
The planarians are a group of "flat worms" that previously corresponded to the class Turbellaria, which is why they are also called as peat bogs. Around 4500 species are known, most of them aquatic in benthic ecosystems, although there are also species adapted to humid environments on land.
The vast majority of planarians are free-living animals, unlike the rest of flatworms that are totally parasitic. Most are aquatic and live in the bottoms (benthos) feeding on other small animals or on remains of decomposing organic matter.

This image shows the ionic bond between sodium and chloride in NaCl (table salt), and the covalent bond between oxygen and hydrogen in H2O (water.) How are the bonds different?molecular structure
Question 3 options:
The hydrogen transfers its electrons to oxygen in water; sodium and chlorine in salt share their electrons.
The hydrogen and oxygen atoms in water share their electrons; sodium transfers an electron to chlorine in sodium chloride.
The oxygen transfers its electrons to hydrogen in water; sodium and chlorine in salt share their electrons.
Answer:
B. The hydrogen and oxygen atoms in water share their electrons; sodium transfers an electron to chlorine in sodium chloride.
Explanation:
The bonds between sodium and chloride in NaCl (table salt), and oxygen and hydrogen in water are different as sodium and chloride in NaCl have ionic bond and oxygen and hydrogen in water have the covalent bond.
Sodium transfers an electron to chlorine in sodium chloride (NaCl), so that they both have full outer shell and form ionic bonds. sodium and chloride ions exerts electrostatic force on each other and bond together with ionic bonds.
The hydrogen and oxygen atoms in water have covalent bonds because they are bonded by sharing electrons. Both hydrogen and oxygen atoms share unequal electrons with each other and form V-shaped water molecule.
Hence, the correct answer is "B."
