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:

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.

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.

The cell theory meets the definition of a scientific theory but i do not think it should be a scientific law.

proteins: eggs and beef, lots of animal derived foods contain proteins since thy are the basis of life.

Explanation:

Here are two examples for each of the three macromolecules; Carbohydrates; Bread, Rice. Lipids (Fats); Avocado, Salmon. Proteins; Chicken Breast, and Beans.

Carbohydrates;

Bread; Bread is rich in carbohydrates, primarily in the form of starch. It provides a quick source of energy due to its high carbohydrate content.

Rice; Rice, especially white rice, is another significant source of carbohydrates. It is a staple food in many cultures and contributes to daily energy intake.

Lipids (Fats);

Avocado; Avocado is a fruit that contains healthy monounsaturated fats. It is often used in salads, spreads, and various dishes.

Salmon; Salmon is a fatty fish that provides omega-3 fatty acids, which are essential for heart and brain health.

Proteins;

Chicken Breast; Chicken breast is a lean source of protein, low in fat. It is commonly consumed for its high-quality protein content.

Beans; Legumes such as beans (e.g., kidney beans, black beans) are rich in plant-based proteins. They are a staple in many vegetarian as well as vegan diets.

b) Nucleic acids are made up of a sugar, a sulfate, and a phosphate. option b is incorrect.

Explanation:

Nucleic acids are made up of of a sugar, a phosphate, and a nitrogen base.

Hence all options are correct except b.

Hope this helps.

The incorrect statement is option b i.e., nucleic acids are made up of a sugar, a sulfate, and a phosphate.

Nucleic acids are large biomolecules that are required by all cells and viruses to function.

Nucleic acids play an important role in the storage and expression of genomic information. DNA, or deoxyribonucleic acid, encodes the information that cells require to produce proteins.

Nucleic acids are massive biomolecules composed of monomers known as nucleotides. Nucleotides are made up of three parts including a pentose sugar (5-carbon sugar), a phosphate group, and a nitrogenous base.

There are two types of nucleic acids: natural and synthetic nucleic acids.

Nucleic acids are macromolecules composed of nucleotide units that occur naturally in two forms namely deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).

DNA is the genetic material found in all living organisms, from bacteria to multicellular mammals.

Thus, the correct option is b.

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.

Answer: A!

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.

Melting point: 1536 °C

Ionic radius: 0.076 nm (+2); 0.064 nm (+3)

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.

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:

The broadest, most inclusive level of organization is the biosphere. This includes both biotic and abiotic components of the earth and the part of the atmosphere that supports life.

The Habitat is an ecological level that does not describe interacting biotic and abiotic factors in an area.

Habitat may be defined as a type of natural environment for which a particular species is best adapted due to natural selection. In other words, it may also be characterized as the area where the basic demands of an organism are fulfilled like food, space, and mating partner.

Habitat is something that only signifies the effect of abiotic factors which are favorable for the survival of any individual of any species under controlled variations.

In this question, the rest of the options include the biome, community, and ecosystem. All such ecological levels significantly illustrate the interaction between biotic and abiotic factors of a given area.

Therefore, the Habitat is an ecological level that does not describe interacting biotic and abiotic factors in an area.
