Answer:

C

Explanation:

Natural selection will not occur unless genetic variation has an effect on organism survival and reproduction.

The trait must first be advantageous, or improve the likelihood that the organism will survive and reproduce. In order for a trait to be passed on to an organism's progeny, it must also be heritable.

An evolutionary mechanism is natural selection. Environment-adapted organisms have a higher chance of surviving and dispersing the genes that contributed to their success. Over time, this mechanism leads to the evolution and divergence of species.

The area around a charge in which the electric force is experienced by other charged objects is the electric field.

The electric field is a property of the space around a charged object and is created by the presence of that charge. Any other charged object placed within the electric field will experience a force exerted on it due to the interactions between the electric charges.

The electric field can be thought of as a field of influence that extends throughout space, representing the force that would be experienced by a positive test charge placed at any given point within the field. The strength and direction of the electric field depend on the magnitude and sign of the charge creating the field. Electric field lines, which are used to visualize the electric field, point away from positive charges and towards negative charges.

The electric field plays a crucial role in understanding and describing the behavior of charged particles and the interactions between them. It is a fundamental concept in electromagnetism and has applications in various fields, including electronics, electrical engineering, and physics.

Answer:

At the respiratory membrane, where the alveolar and capillary walls meet, gases move across the membranes, with oxygen entering the bloodstream and carbon dioxide exiting. It is through this mechanism that blood is oxygenated and carbon dioxide, the waste product of cellular respiration, is removed from the body.

All of the given statements are true about Calvin cycle:

Calvin cycle is the first process of light-independent reactions where the inorganic carbon dioxide is trapped from environment to convert it into a stable organic molecule. There are three steps of Calvin cycle: carbon fixation, reduction and regeneration.

Reduction phase of the Calvin cycle is where the first stable organic product of the Calvin cycle undergoes reduction to form glyceraldehyde-3-phosphate (G3P).

2. The organ system that helps waste gases such as carbon dioxide leave the body is the respiratory system.

3. The organ system that includes the brain is the nervous system.

4. The kidneys and the urethra are part of the urinary system.

1.The circulatory system is the organ system in charge of delivering nutrients, gases, and hormones throughout the body. It consists of the heart, blood vessels, and blood, which work together to transport oxygen, nutrients, hormones, and waste products throughout the body. The heart pumps oxygenated blood to the tissues, delivering nutrients and oxygen, while the blood vessels act as a network of highways to distribute these substances to cells and organs.

2. The respiratory system is the organ system that assists waste gases such as carbon dioxide in leaving the body. The lungs, airways, and respiratory muscle are all part of it. During respiration, oxygen is taken in and carbon dioxide is removed from the body. The lungs exchange gases by inhaling oxygen-rich air and exhaling carbon dioxide.

3. The nervous system is the organ system that contains the brain, as well as the spinal cord and nerves. The brain is the body's command and control Centre, coordinating and regulating many physical activities and processes.

4. The kidneys and the urethra are part of the urinary system. The urinary system is responsible for filtering waste products, excess water, and toxins from the blood, producing urine, and eliminating it from the body.

If the hydrogen ion pumps in the tiger's mitochondria stopped functioning, it would have severe consequences on the process of oxidative phosphorylation and the overall production of ATP (adenosine triphosphate), which is the energy currency of cells.

The hydrogen ion pumps, also known as the electron transport chain complexes, play a crucial role in oxidative phosphorylation. They are responsible for creating a proton gradient across the inner mitochondrial membrane by pumping hydrogen ions (protons) from the mitochondrial matrix to the intermembrane space. This proton gradient is essential for the functioning of ATP synthase, an enzyme that synthesizes ATP.

Without functioning hydrogen ion pumps, the proton gradient would not be established. As a result, ATP synthase would not be able to generate ATP efficiently. This would lead to a significant reduction in ATP production, which is essential for various cellular processes, including muscle contraction, biosynthesis of molecules, active transport, and maintenance of cellular homeostasis.

The lack of ATP production would cause a rapid depletion of cellular energy reserves. Cells would struggle to carry out their normal functions, and the tiger would experience a loss of energy and overall decline in physical performance. Vital processes such as muscle movement, digestion, and even basic metabolic functions would be compromised.

Additionally, the accumulation of hydrogen ions within the mitochondrial matrix would disrupt the pH balance, affecting the efficiency of other metabolic pathways and potentially leading to cellular damage or dysfunction.

In summary, the dysfunction of hydrogen ion pumps in the tiger's mitochondria would severely impair ATP production, resulting in a decline in energy levels and overall cellular function. It would have significant implications for the tiger's survival and well-being.

Answer: True

Explanation: As sediment is transported by erosion, it can become sorted by grain size. The reason for this is because gravity forces the heavier particles to settle out first, while the lighter and smaller particles are carried further. This process is called sorting; sorting can render the separation of particles by grain size as it is transported by erosion.

Fossils are animals and vegetable remains that get deposited or printed in sedimentary layers. Option A is correct: There have been changes in Earth's lifeforms over time.

Fossils are animal and vegetable rests found in different strata of sedimentary rocks. Sedimentary layers deposit chronologically, so they are used to reflect history. They keep in each layer some of the forms of life that inhabited that area in the past.

Fossils are very useful while dating ages. Index fossils are the fossilized organizms that only used to exist in a given era or geological period during evolution.

Fossil registers show that similar or different structured have been inhabiting the same area in the same period of time.

According to this framework, we can assume option A is correct: There have been changes in Earth's lifeforms over time.

Explanation:

Enzymes are specialized proteins that function as biological catalysts- they speed up chemical reactions. As proteins, these are susceptible to changes in temperature and pH- they function best at optimal values for both conditions, but can be denatured, rendering them inactive at relative extremes.

Each enzyme provided has its own optimal temperature and pH values.

Thus from the table A- pepsin, B- Amylase and C- thermophilic enzyme can be hypothesized.
