Ribosomes, Rough endoplasmic reticulum (RER), and golgi apparatus- all the three organelles participate in the packaging of proteins. Proteins synthsized in ER, are packed in the golgi apparatus.

Golgi apparatus is the main organelle which is responsible for the packaging and transportation of the proteins, and lipids. The nucleolus present in the nucleus is responsible for the synthesis of ribosomal RNA (rRNA) and proteins. Ribosomes are responsible for the synthesis of protein.

Proteins generated by the ribosomes in the endoplasmic reticulum are packed in the Golgi apparatus, where lipids are wrapped around them in a membrane which is then exported out of the cells. Molecules which enter the Golgi apparatus are charged, stored, and then released into the cytoplasm in the form of secretory vesicles to the final destination.

Answer: Option (c) is the correct answer.

Explanation:

It is known that chemical changes are the changes which tend to show difference in chemical composition of a substance.

For example, toxicity, reactivity, combustion etc are all chemical properties.

When gasoline is burning then a chemical change takes place as combustion is taking place.

A chemical change will always lead to the formation of a new compound and this change is irreversible in nature by any physical means.

On the other hand, a change which is unable to bring any difference in chemical composition of a substance is known as a physical change.

For example, change in shape, size, mass, volume etc are all physical properties.

Breaking glass, melting ice on windshield and denying a bumper are all physical changes.

Thus, we can conclude that out of the given options burning gasoline is an example of chemical change.

In cellular respiration, glucose is used as the primary fuel to produce ATP, while oxygen acts as an essential electron acceptor for efficient ATP production. Without oxygen, much less ATP is produced, demonstrating the necessity of both glucose and oxygen in energy metabolism within cells.

During the process of cellular respiration, glucose and oxygen play critical roles. Glucose serves as the primary fuel, with its breakdown releasing the energy necessary for the synthesis of adenosine triphosphate (ATP). Oxygen, meanwhile, is crucial for accepting electrons at the end of the electron transport chain, allowing for the efficient production of ATP. Without oxygen, only a limited amount of ATP can be produced through anaerobic pathways.

Glucose enters the body from food intake and is transported by the cardiovascular system from the digestive system to the cells. Oxygen is inhaled into the lungs, diffuses into the bloodstream, and is also carried to the cells. In the presence of oxygen, cellular respiration begins with glycolysis, releasing just two molecules of ATP, and culminates in the mitochondria through the citric acid cycle and the electron transport chain. This leads to the production of the majority of ATP, with carbon dioxide and water as waste products.

Most steps of cellular respiration, including the final and most ATP-productive ones, occur within the mitochondria of cells. All organisms that require oxygen perform cellular respiration to convert glucose into the usable energy of ATP. The overall transformation during cellular respiration involves the consumption of glucose and oxygen and the release of carbon dioxide, water, and ATP. As a result, cellular respiration is essential for powering various cellular processes across organ systems, notably involving the digestive, cardiovascular, and respiratory systems.

Final answer:

In cellular respiration, glucose is broken down with the help of oxygen to produce ATP, carbon dioxide, and water. Oxygen's crucial role is to serve as the final electron acceptor in the electron transport chain, allowing for efficient ATP production. Without oxygen, the ATP yield would be greatly reduced.

Explanation:

Glucose and oxygen play crucial roles in the process known as cellular respiration, which is the method by which cells convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products. Oxygen acts as the final electron acceptor in the electron transport chain, which is necessary for the production of ATP. Without oxygen, the electron transport chain would not function, significantly reducing the amount of ATP produced by cellular respiration.

In the presence of oxygen, glucose undergoes a series of reactions that result in the production of carbon dioxide and water as waste products, and the most importantly, ATP, which is the main energy currency of the cell. Each molecule of glucose, through the process of cellular respiration, can produce a significant number of ATP molecules, which the cell uses for various energy-requiring functions.

Cellular respiration is a multi-step process starting with glycolysis, continuing through the citric acid cycle, and concluding with oxidative phosphorylation at the electron transport chain. This intricate process involves the digestive, cardiovascular, and respiratory systems, as glucose comes from the food we eat, and the oxygen needed for respiration is obtained from the air we breathe.

Density of liquid having a volume of 30.0 mL and a mass of 6 g is

[tex]0.2 \frac{g}{ml}[/tex]

Explanation:

Density of a substance is given by mass divided by volume

Mathematically it can be represented as

[tex]D = \frac{M}{V}[/tex]

Where D represents the density

M represents the mass and

V represents the volume

Substituting the given values in above equation we get -

[tex]D = \frac{6}{30} \\= 0.2\frac{g}{ml} \\= 200 \frac{Kg}{m^3}[/tex]

Hence, density of liquid having a volume of 30.0 mL and a mass of 6 g is

[tex]0.2 \frac{g}{ml}[/tex]

The option which is true about algae, bacteria, and flowering plants is that they all are composed of cells. Thus, the correct option for this question is A.

Bacteria may be defined as single-celled, prokaryotic, and microscopic organisms that lack a well-defined nucleus and other membrane-bound cell organelles. They are most potent to cause numerous diseases in plants and animals.

Except for cyanobacteria, none of the other bacteria have chlorophyll. Some photosynthetic algae have only chlorophyll, while almost all flowering plants possess a chlorophyll pigment.

According to the three premises of the cell theory, all living organisms whether plants or animals are made up of cells because a cell is the only one that is the structural and functional unit of life for each living entity.

A molecule is a saturated fat when it consists of carbon chains having only single bonds between carbons, making it fully 'saturated' with hydrogen atoms. These fats have straight chains, can pack tightly together, and are solids at room temperature.

A molecule is classified as a saturated fat when it is a type of simple lipid molecule with a carbon chain bonded to the maximum number of hydrogen atoms possible. This means that each carbon atom in the chain is linked to adjacent carbons by single bonds only, without any carbon-to-carbon double bonds (C=C). Saturated fatty acids comprise these simple lipid molecules and contribute to the molecule's straight chain structure, which allows them to pack closely together. Consequently, saturated fats tend to have high melting points and are typically solids at room temperature.
