C) A red blood cell and hair follicle cell have the same genes, but they are expressed differently

Explanation:

All cells of a living organism contain the same genetic sequence i.e. they contain the same set of genes, however, differences in the expression of these genes may occur. This is responsible for the different specific roles or functions played by organs of the body system.

The expression of a gene refers to the process by which a gene is transcribed and translated into a protein molecule, which is responsible for traits in the body. Genes are expressed differently in order for certain cells to function differently and specifically. For example, difference in expression of genes is responsible for the ability of red blood cells to produce hemoglobin and the inability of hair follicle cells to, even if they contain same genes.

Bones are covered as well as lined by a protective tissue renowned to as periosteum. The inner layer comprised basically of osteoblasts and osteoclasts.

Osteoblasts are in charge of creating new bones and are essential for bone growth and repair.

They create and secrete the collagen and other organic elements of the bone matrix, which helps to speed up mineralization.

On the other side, osteoclasts are involved in the process of eliminating and disintegrating old or damaged bone tissue, which is known as bone resorption.

The mineralized matrix is broken down by the enzymes and acids they produce, allowing for the remodelling and reshaping of bones.

Thus, together, osteoblasts and osteoclasts keep the ratio of bone creation to resorption in check, which benefits the general well-being and structural integrity of bones.

Cumulus clouds are one of the three basic types of clouds classified according to their height and shape. These clouds are white and fluffy with a flat base and a rounded top, resembling a cotton ball or cauliflower.

Cumulus clouds form through convection as warm air rises and cools, and the moisture in the air condenses to form visible water droplets. Cumulus clouds are typically associated with fair weather, but they can also indicate the potential for thunderstorms.

Cumulus clouds are important in the water cycle because they are responsible for releasing precipitation in the form of rain, hail, or snow. As the cloud grows and reaches higher altitudes, the water droplets inside it continue to grow through collision and coalescence. Eventually, the droplets become too heavy to be supported by the updrafts that created the cloud, and they fall to the ground as precipitation. The size of the droplets and the temperature at different altitudes determine the type of precipitation that falls from the cloud.

The cloud type that will only produce precipitation by the collision-coalescence process is cumulus clouds.

Key stone species should be protected from hunting or gathering in order to keep the healthiest ecosystem. One illustration of a keystone species in North America is the American Beaver (Castor canadensis).

Claim: Some species are essential to the survival of the other species in the ecosystem in every environment.

Reason: A large predator or a little plant could be the keystone species, but without them the ecosystem might not exist. If a keystone species vanished, some ecosystems might not be able to adjust to environmental changes.

Evidence: Often, it takes the extinction of a keystone species for the importance of that species in an ecosystem to be fully understood. Robert Paine, an ecologist who popularised the phrase "keystone species" in the 1960s, discovered the significance of such species while researching starfish along Washington state's rugged Pacific coast.

The option (B) is correct. ATP

Adenosine triphosphate (ATP) is the source of energy for use and storage at the cellular level. The structure of ATP is a nucleoside triphosphate, consisting of a nitrogenous base (adenine), a ribose sugar, and three serially bonded phosphate groups.

Moreover, adenosine triphosphate is an organic compound that provides energy to drive many processes in living cells, such as muscle contraction, nerve impulse propagation, condensate dissolution, and chemical synthesis.

Therefore, ATP can be used to store energy for future reactions or be withdrawn to pay for reactions when energy is required by the cell. Animals store the energy obtained from the breakdown of food as ATP. Likewise, plants capture and store the energy they derive from light during photosynthesis in ATP molecules.

The percentage of guanine in DNA can be calculated based on the complementary base-pairing rule. If DNA has 20% adenine, then it will also have 20% thymine. Since the total percentage of bases in DNA must add up to 100%, the remaining percentage will be divided equally between guanine and cytosine. Therefore, the percentage of guanine in this case will be 30%. The correct option is B.

According to the complementary base-pairing rule in DNA, adenine (A) pairs with thymine (T) through two hydrogen bonds, and guanine (G) pairs with cytosine (C) through three hydrogen bonds. In a DNA molecule, the total percentage of adenine and thymine is equal to the total percentage of guanine and cytosine.

If DNA has 20% adenine, it means it also has 20% thymine because of base-pairing. Together, adenine and thymine make up 40% of the DNA. Since the total percentage must add up to 100%, the remaining 60% will be divided equally between guanine and cytosine.

Therefore, the percentage of guanine in the DNA will be 30% (half of the remaining 60%). The options provided in the question can be eliminated, and the correct answer is B. 30%.

Mitochondria are able to use the hydride ions carried by FADH₂ to make ATP through the electron transport chain and oxidative phosphorylation.

The electron transport chain consists of four protein complexes (I, II, III, IV) and electron carriers that are embedded in the inner mitochondrial membrane. Electrons carried by FADH₂ enter the electron transport chain at complex II and are transferred to complex III via ubiquinone (CoQ) which forms part of the electron transport chain.The energy released by the transfer of electrons between the complexes is used to transport protons (H+) across the inner mitochondrial membrane from the mitochondrial matrix to the intermembrane space.

The proton gradient created across the inner mitochondrial membrane is used by the ATP synthase to generate ATP from ADP and inorganic phosphate. This process is known as oxidative phosphorylation.The reason why FADH₂ produces less ATP than NADH is that the entry of electrons into the electron transport chain at complex I generates a larger proton gradient than entry at complex II. This is because the electrons from NADH are transferred to complex I which pumps more protons across the inner mitochondrial membrane than complex II. Therefore, NADH generates more ATP than FADH₂ because it generates a larger proton gradient.

The likely source of the 1918 and 1968 influenza pandemic strains were both avian-origin viruses. The 1918 strain is thought to have originated from an avian H1N1 virus, while the 1968 strain resulted from the recombination of an avian H3N2 virus with a human H2N2 virus. Both strains are believed to have arisen via recombination, also known as genetic reassortment.

We know this through scientific research and analysis of the viral genome sequences. Researchers have been able to study preserved samples of the virus from infected individuals and compare the genetic material with those of known avian and human viruses.

Most of the ATP produced by aerobic cellular respiration is made by oxidative phosphorylation

Oxidative phosphorylation is responsible for the majority of the ATP generated by aerobic cellular respiration. Protons are pumped through a membrane to produce a chemiosmotic potential using the energy released. Then, ATP synthase is engaged by this potential to synthesis ATP from ADP and a phosphate group. During aerobic respiration, glucose and oxygen combine to produce ATP, which the cell can utilise. As products, water and carbon dioxide are produced. In the general equation for aerobic cellular respiration, glucose and oxygen combine to create ATP. Oxidative phosphorylation is the biochemical cycle that generates a most net ATP per molecule of glucose. The majority of ATP synthesis takes place during cellular respiration in the mitochondrial matrix, producing about 32 ATP molecules for every glucose molecule.
