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."

Answer:
Diffusion
Explanation:
Diffusion can be explained or described as the movement of molecules from the region of higher concentration to the region of lower concentration.
It should be understood that this process is different from osmosis in that, osmosis requires a semi permeable membrane while diffusion does not.
In this sense, diffusion is considered to have occurred in both the activities.
37. What is the distance from Passas Street at the
margin of the map to where it meets Route 84?
Answer:
3 1/2
Explanation:
The distance from Passes Street at the margin of the map to where it meets Route 84 is 3 1/2 miles.
What are measurements?The comparison of an unknown amount with a known quantity is referred to as measurement. The measurement yields a numerical value with specific units. Any given object's length, mass, capacity (volume), and temperature can be measured.
Distance is defined as an object's entire movement without regard for direction. The distance can be defined as how much ground an object has covered, regardless of its starting or ending place.
Mile, any of several distance units, such as the statute mile of 5,280 feet (1.609 km). It was derived from the Roman mille passus, or "thousand paces," which was equivalent to 5,000 Roman feet.
Therefore, the distance from Passes Street at the map's edge to where it intersects Route 84 is 3 1/2 miles.

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.

prey
The mistletoe's role in this relationship is a parasite. The correct option is C, parasite.
Mistletoe is a parasitic plant that grows on other plants, typically trees and obtains water and nutrients from its host plant.
What is a parasitic relationship?
A parasitic relationship is a type of relationship between two organisms where one organism, known as the parasite, benefits at the expense of the other organism, known as the host.
The parasite obtains various resources such as nutrients, water, shelter, or even a place to reproduce from the host organism.
The root-like structures of mistletoe, called haustoria, penetrate the host plant's tissues and extract water, minerals, and sugars.
This relationship is considered parasitic because mistletoe benefits at the expense of the host plant, potentially causing harm or weakening the host's health.
Therefore, the correct option is C.

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.

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.
