Geographic isolation is a process that occurs when a physical barrier separates a population, preventing or limiting gene flow between them. The importance of geographic isolation is supported by the fact that it is a critical factor that leads to the development of new species.

In the article, the speciation of plants is mentioned as one of the factors that support the importance of geographic isolation. When populations of plants become isolated from each other, they can develop unique genetic variations and adaptations that can eventually lead to the evolution of a new species.

Additionally, the distribution and abundance of organisms can also support the importance of geographic isolation. If a species is restricted to a specific area due to physical barriers, such as mountains or water bodies, it may have a smaller population size and limited gene flow with other populations. This can result in genetic differences and eventually lead to speciation.

The Antarctic convergence is another example of geographic isolation that supports its importance. This region marks the boundary between the cold Antarctic waters and the warmer waters to the north. This physical barrier limits the mixing of marine organisms and promotes the development of unique species in both regions.

Therefore, the correct boxes to check in support of the importance of geographic isolation as stated in the article are: speciation of plants, distribution and abundance of organisms, and Antarctic convergence.

Selection: Organisms live within ecosystems, which are made up of various biotic and abiotic factors. These factors contribute to selecting which variations provide the individual with an increased chance of surviving. ... Examples of abiotic factors include temperature, shelter, sunlight, water and nutrients.

Answer:

Biotic and abiotic factors are the environmental conditions that the organisms have to face to live in a specified environment.

Abiotic factors

Abiotic factors are the physical and chemical conditions of an environment. For example : heat, salinity, pressure, light, wind, pH ...

Biotic factors

Biotic factors are all the biological conditions of an environment for a specie/taxa. It can include prey and predator abundance, available food amount, available space, intra and interspecific competition...

The development of organims is under the control of abiotic factors. Some are adapted to heat, cold etc ... The abiotic factors will define which organisms are able or not to live in a specified place.

The living organisms will constitute the biotic factors, which define if and how can an organism live in a specified environment.

So, the abiotic factors are controling the biotic factors of an environment.

Biodiversity decreases because plants and animals adapted for fresh water will not survive and reproduce in a different environment.

The term sea rise has to do with a situation in which there is a sudden increase in the sea level. This could lead to a sudden overflow of water into rivers lakes and ponds.

We know that sea water is salty, there is excess salt concentration in a sea water while fresh water does not contain salt at all. In these cases whereby there is an overflow of seawater, the water carries salt along with it. This implies that land and fresh water could become contaminated with this salt and that would have catastrophic effects on these ecosystems.

Since fresh water organisms can not tolerate a sudden increase in the concentration of salt in the ecosystem, biodiversity decreases because plants and animals adapted for fresh water will not survive and reproduce in a different environment.

An iron cube has sides that measure 0. 5 meter. The cube is cooled from 95°C to 75°C. the change in volume of the iron cube is -9 × 10⁻⁵ m³.

The change in volume of the iron cube can be calculated using the formula: ΔV = 3αV₀ΔT, where ΔV is the change in volume, α is the coefficient of linear expansion, V₀ is the initial volume, and ΔT is the change in temperature.
Given:
α = 12 × 10⁻⁶ °C⁻¹ (coefficient of linear expansion for iron)
V₀ = 0.5³ = 0.125 m³ (initial volume of the cube)
ΔT = 75 - 95 = -20°C (change in temperature)
Plugging in the values into the formula:
ΔV = 3αV₀ΔT
ΔV = 3 × 12 × 10⁻⁶ °C⁻¹ × 0.125 m³ × (-20°C)
ΔV = -9 × 10⁻⁵ m³

heredity is defined as the characteristic we get genetically from our parents and our relatives before them. an example of heredity is a likelihood that you will have blue eyes. an example of heredity is your possibility of having cancer based on family history

Explanation:

Characteristics like eye colour, hair colour etc are examples of heredity.

The genetic-based heritage passed down to us from our parents is referred to as heredity. It can also be defined as traits transferred from one generation to the next one.

Blood groups and eye colour are common examples of these traits. Heredity can even transmit some diseases from the parents to the offspring. These are called hereditary diseases or genetic diseases. These diseases are usually non-curable.

These are genetic traits and a thus determined by the genes. Also, there are multiple variants of a single gene. These are called alleles. Every gene in our cells is present in 2 copies, except genes on sex chromosomes. These two copies can either be identical and be called homozygous, or they can be different and be called heterozygous.

The gene which is expressed as the phenotype is called dominant and the one which is not expressed is called recessive.

Therefore, heredity is the traits obtained from the biological parents.

Answer:

Hypotonic

Explanation:

Answer:

True

Explanation:

A general misconception is that insulin is only involved in energy and fat metabolism.  When energy needs are high, insulin transports sugar from the blood into the muscle where it can be converted into energy.  When energy needs are low, insulin facilitates the conversion of excess sugar into fat where it can be stored for future use.

What is often overlooked is the powerful effect of insulin on stimulating muscle protein growth and repair.  An essential action of insulin is to increase the transport into muscle of amino acids, the building blocks of protein, where they can be used for rebuilding and repair. Insulin’s anabolic effects do not end there. Insulin also plays an important role in turning on one of the metabolic switches that control protein synthesis.

This action explains why combinations of carbohydrate and protein are far more effective in stimulating protein synthesis than protein alone.  Two switches are responsible for turning on protein synthesis.  One is activated by protein, specifically amino acid levels in the blood, and the second by insulin.  Consuming carbohydrate (which raises insulin levels) and protein in your recovery drink gives you a dual benefit.  In fact, research has shown that a carbohydrate protein drink is 38% more effective than a protein drink in stimulating muscle protein synthesis post exercise.

Another important effect of insulin is inhibition of protein breakdown.  At any given time, muscle protein is in a state of flux – it is being synthesized and broken down.  When more protein is synthesized than broken down, you have a net gain in lean body mass.  After exercise, protein degradation is higher, primarily because during extended endurance activity up to 20% of the working muscle’s energy is derived from protein.  That’s why consuming protein in your sports drink offers significant advantages.  It reduces the amount of muscle protein used for energy.  Higher breakdown rates of protein after exercise increases muscle soreness and slows the overall recovery process. By inhibiting protein breakdown, insulin mediates a faster recovery.

The bottom line – by taking advantage of how and when insulin works and how nutrition can affect insulin activity, endurance athletes can optimize muscle recovery and achieve significant improvements in endurance performance.
