Red blood cells are the smallest cells in the body. So, they can easily diffuse through a capillary and facilitate oxygen transport.

Red bloods cells (RBCs), also called as erythrocytes are the chief cells present in the blood stream.

Red blood cells contain a red coloured pigment called haemoglobin. This pigment has affinity for oxygen and thus is important for oxygen exchange in the body.

Mammalian Red blood cells are biconcave, disc shaped and lack nucleus (exception frog).

Red blood cells are produced in the bone marrow and are degraded in spleen.

Red blood cells have an average life span of 120 days in the circulatory system.

The number of red blood cells is little higher in males as compared to females. Low Red blood cell count in the body leads to a medical condition called anemia.

Therefore, Red blood cells are important for transport of gases in the body.

Plant cells and cyanobacteria (also photosynthetic) get the ATP they need to power their regular cellular processes from: b. Cellular respiration

Plant cells and cyanobacteria are photosynthetic organisms that are capable of producing their own food through the process of photosynthesis. During this process, they use light energy to convert carbon dioxide and water into glucose and oxygen. However, to power their regular cellular processes, including protein synthesis, DNA replication, and cell division, they need a constant supply of energy in the form of ATP.

The ATP required by plant cells and cyanobacteria is produced through the process of cellular respiration. While photosynthesis produces glucose and oxygen, cellular respiration breaks down glucose molecules to release energy in the form of ATP. This process takes place in the mitochondria of plant cells and cyanobacteria.

Cellular respiration can be divided into three stages: glycolysis, the Krebs cycle, and oxidative phosphorylation. In the first stage, glycolysis, glucose molecules are broken down into pyruvate, which releases a small amount of ATP. In the second stage, the Krebs cycle, pyruvate is converted into acetyl-CoA, which enters a cycle of reactions that produces more ATP and carbon dioxide. Finally, in the third stage, oxidative phosphorylation, electrons from the Krebs cycle are passed through a series of protein complexes, which creates a proton gradient across the mitochondrial membrane. This gradient is then used to power ATP synthesis.

While photosynthesis also produces ATP through the light reactions, this ATP is primarily used to power the process of photosynthesis itself, rather than the regular cellular processes of the plant cell or cyanobacterium. Therefore, the correct answer to the question is b. Cellular respiration.

The Phylogenetic Species Concept would be the most useful to a team of biology students conducting a biodiversity survey on their campus. This concept is based on the evolutionary history of organisms and focuses on the evolutionary relationships between species. It is useful for identifying species boundaries and understanding the evolutionary history of a given group of organisms.

The species concept most useful to a team of biology students conducting a biodiversity survey on their campus would be the Biological Species Concept. This concept defines a species as a group of individuals that are able to interbreed and produce viable, fertile offspring. This concept is useful because it provides a clear and objective way to identify species based on their reproductive capabilities.

To use this concept, the team of biology students would first need to collect data on the various organisms they encounter on their campus. They would need to document the physical characteristics of each species as well as any other ecological or behavioral data that might be relevant to their survey.

Once the data has been collected, the team of biology students would need to determine which organisms on their campus were able to interbreed. This could involve observing mating behaviors or conducting genetic tests to assess whether two individuals were related.

Once the team has identified which organisms are capable of interbreeding, they can then assign them to the same species. By using the Biological Species Concept, the team of biology students can more accurately assess the biodiversity of their campus, allowing them to better understand and protect the local ecosystems.

The Ogallala Aquifer, a glacier, and the Pacific Ocean would all be considered water sources.

These diverse natural formations play crucial roles in supplying fresh water and maintaining the global water cycle.

The Ogallala Aquifer, located in the United States, is one of the largest underground sources of fresh water. It spans eight states and provides irrigation for agricultural lands, contributing significantly to the nation's food production.

Glaciers, which are large masses of ice and snow, also serve as freshwater reservoirs. As they slowly melt, they release water into rivers, lakes, and oceans, supporting the ecosystems in their vicinity and providing water for human consumption and agriculture.

The Pacific Ocean, as the world's largest and deepest ocean, contains a vast volume of water. While its water is salty and not directly suitable for human consumption or irrigation, it plays an essential role in the global water cycle. Evaporation from the ocean surface generates atmospheric moisture, which eventually falls as precipitation over land, replenishing fresh water sources.

In summary, the Ogallala Aquifer, glaciers, and the Pacific Ocean are all vital water sources that contribute to sustaining life on Earth through their involvement in the water cycle and provision of fresh water resources.

Successful placement of a cervical spinal cord stimulator lead after anterior cervical discectomy and fusion (ACDF) and posterior cervical fusion is a surgical procedure that aims to alleviate chronic pain and improve the functioning of the cervical spinal cord.

This procedure is typically performed in individuals who have persistent pain following previous cervical spine surgeries.

During the surgery, a cervical spinal cord stimulator lead is implanted near the spinal cord in the cervical region. The lead consists of small electrodes that deliver electrical impulses to the spinal cord, modulating pain signals and providing pain relief. The lead is connected to a pulse generator, which is typically implanted in the chest or abdomen area.

ACDF involves removing a damaged or degenerated cervical disc and fusing adjacent vertebrae together using a bone graft or a metal implant. Posterior cervical fusion involves the fusion of the cervical vertebrae from the back of the neck using bone grafts or screws and rods.

The placement of a spinal cord stimulator lead after ACDF and posterior cervical fusion can help manage chronic pain, reduce reliance on medications, and improve overall quality of life for individuals with persistent cervical spine-related pain. It is typically considered after other conservative treatment options have been exhausted.

During repolarization, calcium channels close and voltage-gated potassium channels open  is the correct answer.

Repolarization is the change in membrane potential that occurs immediately following the depolarization phase of an action potential, which changes the membrane potential to a positive value, and restores it to a negative one. The membrane potential typically recovers to the resting membrane potential during the repolarization phase. Action potentials enter the falling phase as a result of the outflow of potassium (K+) ions. The K+ channel pore's selectivity filter allows the ions to flow through. The open calcium channels pass more calcium ions when the driving force for calcium entry increases during the repolarization of the AP, which causes an increase in calcium influx.
