What are TWO factors that could affect the rate of diffusion?

In classical conditioning, an unconditioned stimulus (UCS) is a stimulus that naturally elicits a reflexive response without any prior learning.

This reflexive response is called the unconditioned response (UCR). The UCS is usually a biologically significant stimulus such as food, pain, or a loud noise. When the UCS is presented, the organism automatically responds with the UCR, which is an innate or reflexive response. In classical conditioning, the UCS is paired with a neutral stimulus, which initially does not elicit the UCR.

After repeated pairings, the neutral stimulus becomes a conditioned stimulus (CS) and elicits a conditioned response (CR) similar to the UCR.

Answer:

B- Loss of muscle movement

Explanation:

The nerves that are trying to send signals from the brain to move are no longer functioning, therefore, the impacted area can no longer move

Answer:

TRUE

Explanation:

The nervous system only exists in animals. Neurons are the nerve cells that compose the nervous system.

The neuron´s principal function is to catch stimuli from the exterior convert them into nerve impulses that get transported to the control centers. These control centers interpret the signal and send an answer to the stimuli.

The control centers in invertebrates are ganglia, while the vertebrate´s control centers are the spinal medulla and the encephalon.

The signal transport occurs from cell to cell in inferior animals and through nerves in superior animals.

There is a progressive increase in the complexity of the nervous system. It evolved from primitive animals to the most superior ones. This evolution is especially noticeable in the development of the encephalon as the control center.

However, the basic nerve cell is very similar in all animals.

False, not all pink flamingos are flying birds.

Some species of flamingos are not capable of flying as adults. They are known as "flightless" flamingos. Only two species of flamingos are flightless and they are the Andean and Punta del Este flamingos. They are the only species of flamingos that are known to have existed as flightless species. However, the most commonly recognized flamingos are the ones that can fly.

Flapping their wings and primarily steering with their tails, birds fly. A bird's wing is both a wing and a propeller, unlike the parts of an airplane. The majority of the wing's supporting surface and propelling force are provided by the wing's basal portion.

Answer:

Absorption: The process of absorbing nutrients occurs primarily in the small intestine. Once the food is broken down into smaller molecules through digestion, these molecules are absorbed into the bloodstream. For example, carbohydrates are broken down into simple sugars, proteins into amino acids, and fats into fatty acids and glycerol.

Circulatory System: The circulatory system, composed of the heart, blood vessels, and blood, plays a crucial role in transporting absorbed nutrients. The blood vessels form an extensive network that reaches all tissues and organs in the body.

Hepatic Portal System: After absorption, most of the nutrients are transported to the liver through a specialized system called the hepatic portal system. This system ensures that the liver, which performs various metabolic functions, receives a concentrated supply of nutrients before they are distributed throughout the body.

Bloodstream Transport: Once in the bloodstream, nutrients are carried by the plasma, the liquid component of blood. Different nutrients use specific mechanisms for transport:

Glucose: It is transported by facilitated diffusion or active transport, depending on the concentration gradient, with the help of insulin.

Amino Acids: They are transported through the bloodstream by specific carrier proteins.

Fats: Dietary fats are initially packaged into structures called chylomicrons and transported through the lymphatic system before entering the bloodstream. Once in the bloodstream, fats are carried by lipoproteins such as low-density lipoprotein (LDL) and high-density lipoprotein (HDL).

Distribution to Tissues: As the blood circulates, nutrients are distributed to various tissues and organs according to their specific needs. Nutrients are delivered to cells through the capillaries, the smallest blood vessels in the body, which have thin walls that allow for the efficient exchange of nutrients and waste products.

Cellular Uptake: Nutrients are taken up by cells through various mechanisms. For instance, glucose enters cells with the help of insulin, while amino acids are transported into cells through specific carrier proteins. Fats are taken up by cells through receptor-mediated endocytosis or by diffusion.

Metabolism: Once inside the cells, nutrients undergo metabolic processes to produce energy or build new molecules. Glucose, for example, can be metabolized through glycolysis, the Krebs cycle, and oxidative phosphorylation to generate ATP, the cell's energy currency.

Waste Removal: Metabolic byproducts, such as carbon dioxide and urea, are generated during nutrient metabolism. These waste products are transported back into the bloodstream and eventually eliminated from the body through the lungs (carbon dioxide) or the kidneys (urea).

It's important to note that different nutrients may have different transport mechanisms and pathways. The body's ability to efficiently transport and utilize absorbed nutrients is vital for maintaining proper functioning and overall health.

During the mid 1930s, G. F. Gause studied competition among three species of Paramecium. Through his experiments he formulated a principle of:

G. F. Gause formulated the principle of competitive exclusion, which states that two species competing for the same resources cannot coexist in the long term.

In his experiments with three species of Paramecium, G. F. Gause observed that when two species were grown together in a limited environment with limited resources, one species would eventually outcompete and eliminate the other species. This occurred because both species were competing for the same resources, such as food and space, and one species would be more efficient or better adapted at utilizing those resources, giving it a competitive advantage.

Over time, the competitively superior species would dominate the available resources, while the weaker species would be deprived and eventually die out. Gause found that no two species could coexist indefinitely when their ecological niches overlapped to a significant extent.

G. F. Gause's experiments and observations led to the formulation of the principle of competitive exclusion, which has since become an important concept in ecology. The principle highlights the intense competition for limited resources in nature and suggests that species with similar ecological requirements cannot coexist in the long term. However, it is important to note that in real-world ecosystems, various factors such as environmental fluctuations, adaptations, and niche differentiation can allow for species to coexist to some extent, even if they compete for similar resources.
