D. 5​

Answer:

A force must be provided to overcome gravity.

Hydrogen bonds in water molecules are formed between hydrogen and oxygen atoms of adjacent molecules. Hence, option c is the correct answer for the statement.

There are various types of bonds, such as covalent bonds, hydrogen bonds, ionic bonds, etc. In covalent bonds, valence electrons are shared; hence, this bond is called a covalent bond. It is one of the strongest bonds. In ionic bonds, two ions, such as an anion and a cation, form a bond. An example is sodium chloride.

The hydrogen bond is not a covalent bond; it is made between oxygen and hydrogen, hydrogen and fluoride, etc. Inside water, each molecule is connected to another by hydrogen bonds. Hydrogen (H) and oxygen (O) of one water molecule make hydrogen bonds with hydrogen and oxygen of another water molecule. Inside a single water molecule, covalent bonds are present between hydrogen and oxygen.

Hence, a hydrogen bond is present between the hydrogen and oxygen atoms of adjacent water molecules. Option C is the correct answer .

Answer:

Oxygen is produced during photosynthesis and used during cellular respiration

Explanation:

Photosynthesis and cellular respiration are two metabolic activities that are considered opposite of one another. This is because the reactants of one serves as the products of the other and vice versa.

- Photosynthesis is the process that occurs in green plants which utilizes CO2 and water in the presence of sunlight to produce glucose and oxygen as products.

- Cellular respiration, on the other hand, occurs in every living cell and uses glucose and oxygen to produce CO2 and water.

Hence, based on the options provided in this question, both processes are opposite of one another because Oxygen is produced during photosynthesis and used during cellular respiration.

The biological procedure of nitrogen fixation alters nitrogen gas into a form that is advantageous to plants and other microbes. Thus, option C is correct.

In response to ambient oxygen and ammonium levels, transcriptional regulation of nitrogen fixing occurs.

It is advantageous for bacteria to suppress transcription when oxygen levels are high because the nitrogenase components are oxygen labile.

Rhizobium bacteria are involved in nitrogen fixation. These bacteria are found in the roots of leguminous plants, such as pea and bean plants, and by fixing nitrogen in the soil through the use of certain enzymes.

Therefore, In this process, atmospheric nitrogen gas is transformed into ammonia and other nitrogenous molecules that are related.

Eating plants. Hope this helps :)

Explanation:

Answer:

By eating plants

Explanation:

The plants uptake the nitrogen by the help of the nitrogen fixing bacteria found in the soil. The nitrogen from the plants is taken by the animals eating the plants. The source of the nitrogen to the animals is the plants containing nitrogen. The plants are also supplied with some of the fertilizers that contains adequate amount of nitrogen in it, which is transferred to the animals when they eat it.

Of the forms of friction listed, a cyclist experience "rolling friction, sliding friction and air resistance" during this type of race.

The rolling friction is known to be the type of friction that when a body rolls on a surface. In this type of friction, there is a force that tends to resist the motion. As the cyclist ride their bicycles, rolling friction occurs between the tyre of the bicycles and the surface of the road.

Sliding friction also occurs during this type of race. It's a contact that actually resists the sliding motion that occurs between two objects - an object and a surface.

Air resistance is the type of friction that occurs when objects move through air. It's a friction between air and an object. In this type of race, air resistance is experienced as the cyclists experience resistance from the air when the ride.
