Answer:

The amount of matter inside the balloon.

Explanation:

4.00 g/mol

Helium, which has a mass of 4.00 g/mol, has a density of 0.164 g/l. Thus, a one-liter balloon of helium can lift a mass of (1.18-0.164) = 1.02 g.

Answer:

The main properties of water are its polarity, cohesion, adhesion, surface tension, high specific heat, and evaporative cooling. A water molecule is slightly charged on both ends. This is because oxygen is more electronegative than hydrogen. The stream of water bends due to the polarity of water molecules.

All the properties of water are related to one another by the polar nature that is caused by the partial electronegativity difference of the hydrogen and oxygen molecules of water molecules.

A water molecule has  uneven distribution of charges between different atoms  of the different molecules. All types of properties of water due to attractions between these polar  molecules.

Answer:

Photosynthesis takes place inside plant cells in small objects called chloroplasts. During photosynthesis, Plants get carbon dioxide from the air through their leaves, and water from the ground through their roots. Light energy comes from the Sun. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.

Explanation: All biological organisms play a part in the earth's ecosystem, but consumers get energy from eating other organisms and producers make energy on their own. Grass is a producer, a self-sustaining organism that obtains its energy from the sun. In the process, it introduces new organic substances into the food chain and plays a key role for consumers. Grass forms the basis of the food chain because of this ability.

Explanation:

it was correct.

photosynthesis and cellular respiration work together to create the life cycle. without Cellular respiration we would die and without photosynthesis we would die. They are equally important without one the other could not function

have a great day

Only anaerobic respiration would take place in the absence of photosynthesis, hence option B is correct.

Oxygen and glucose are used in cellular respiration to create carbon dioxide and water. The equation for photosynthesis is the inverse of the equation for cellular respiration, further emphasizing this concept.

The cycle of cellular respiration and photosynthesis is essential for the survival of humans, animals, and plants. The term "cellular respiration" describes a chain of metabolic processes that convert glucose into water and carbon dioxide and ATP.

Therefore, in the absence of photosynthesis, there would be no glucose or oxygen for respiration, and since photosynthesis requires carbon dioxide, only anaerobic respiration would be possible.

Answer: alkali metals and halogens

Explanation:

The two groups of elements in the periodic table those are the most reactive are alkali metals and halogens. The correct option is C.

The periodic table (also known as the periodic table of elements) is organized so that scientists can quickly determine individual element properties such as mass, electron number, electron configuration, and unique chemical properties.

Non-metallic elements in the periodic table include hydrogen, carbon, nitrogen, oxygen, phosphorus, arsenic, and selenium.

Metals are minerals found underground in rocks, such as iron or lead. Heat is used to separate these from the rocks. Metals are extremely useful.

The periodic table is significant because it is organized to provide a wealth of information about elements and how they relate to one another in a single, easily accessible reference.

The table can be used to predict the properties of elements, including those yet to be discovered.

Considering their valence electrons, the alkali metals and halogens are the two most reactive groups of elements.

Thus, the correct option is C.

Answer:

Enantiomers or optical isomers are chiral molecules which are non-superimposable mirror images of each other. ... Different enantiomers fit differently into the various enzymes that drive biochemistry. This explains why they often taste and smell differently and have different effects as drugs.

Answer:

Cell theory meets the definition of a scientific theory  because it can be proven, it has been tested for a long period of time and therefore there are many evidences that support the theory but not enough to become a law. Well scientific laws are statements based on repeated experiments or observation, but also, a law is something that always applies under the same conditions. Evolution occurs in the characteristics of living things within a species overtime. . A theory is much more complex: it explains why something happens. A law only describes what happens.

Answer:

Explanation:

The different climates of the Earth are governed by their average annual precipitation and temperature. By plotting a graph (as shown below) of the relationship of these two variables we can determine a region where similar types of organisms can exists no matter where the biome occurs on the planet.

Graphing biomes is a good way to assess average annual precipitation and temperature because biomes depend on climate and climate change occurs due to changes in annual precipitation and temperature.

A biome is a place that is defined by the type of organisms present there. The temperature, soil, and presence of water and food are unique in a biome that makes suitable conditions for species.

Graphing a biome can tell us which animals are living there, and the changes in the environment of a biome can tell about the changes happening in the lives of the organisms.

Thus, because biomes depend on climate and climate change is a result of variations in yearly precipitation and temperature, graphing biomes is an effective technique to evaluate average annual precipitation and temperature.

Explanation:

Answer:

You could check the pH!

Explanation:

This is an idea, when you break down H2O2 (Hydrogen peroxide) you will be left with H2O (Water) and O2 (Oxygen gas). H2O2 theoretically would have a lower pH than water. Water has an average pH of around 7 while H2O2 will have a pH of about 4.5.

So theoretically to figure out if hydrogen peroxide is being broken down you can test for the pH. This is a very simply process, you just stick a little peice of litmus paper into the solution and immediatly it will change color to tell you the pH.
