Answer:

A

Explanation:

Before we try to answer the question lets define a few key terms

Key Terms:

Carrying capacity - The max population that can be sustained by the amount of resources in a specific environment

Limited factor are usually expressed as a lack of a particular resource.

Now lets look back at the answer choices

For A,

A. When resources are available, populations grow until they reach carrying capacity.

This statement makes sense because with available resources, a population will continue to increase until the amount of resources isn't enough for the population, in other words the population will increase until its reached its carrying capacity. So this might be the answer, however lets look at the other answer choices just in case.

For b,

B. The more limiting factors affect a population, the greater the population growth.

This statement would not be true because limiting factors usually are expressed as a lack of a particular resources. A lack of resources ( more limiting factors ) would lead to a population decreasing, not increasing, therefore B is not a true statement

For C,

C. The carrying capacity will decrease when there are no limiting factors affecting the population.​

This statement would not be true because if there are no limiting factors ( which remember are expressed as a lack of particular resource ) the carrying capacity ( or the max population that can be sustained by the amount of resources in a specific environment ) would not change at all because there are no limiting factors changing the availability of the resources, therefore C is not the answer.

Answer:

C

Explanation:

Answer:

Our energy supply comes mainly from fossil fuels, with nuclear power and renewable sources rounding out the mix. These sources originate mostly in our local star, the Sun.

That light energy will be absorbed and converted to heat. Then it will radiate out into space as infrared thermal radiation. It will travel in that form for a long time, once it gets out of the Earth's atmosphere.

Answer:

They are made up of protein.

Explanation:

Through out the cells life they all need protein to keep function.

The name of the structure labeled as A is 'myosin'. Moreover, the name of the structure labeled as B is 'actin'.

A sarcomere is the basic unit of muscle contraction. This unit is defined as the region between two Z-lines.

Band A is a central band composed of the thick filaments of myosin.

Moreover, the sarcomere also has two halves of a band known as I-band, which consists of thin filaments of actin.

Muscle contraction is caused by the interaction between actin and myosin protein filaments in the sarcomeres.

Resolution is the ability that a microscope has to distinguish fine details. Without making any other adjustments the RESOLUTION can be increased by focusing properly in a brightfield microscope.

A brightfield microscope (also called compound light microscope) is a light microscope that produces dark images against a bright background.

The brightfield microscope is widely used in cellular biology and microbiological laboratories.

The resolution of the brightfield microscope is limited to 0.2 micrometers (µm).

This maximum value can be reached by changing the objective lens.

Answer:

The ability of flight allows them to migrate to different plants if needed. They can only leave a plant and walk away if there is a predator or if their food source's quality has deteriorated, otherwise they remain on their original host plant until then.

Answer:

True.

Explanation:

Bryophytes lack the conventional vascular tissues which usually contain the substance lignin. Without vascular tissues, these plants have no means of transporting water and/or nutrients from their lower organs to the higher organs which explains their limited height.

Abstract -

The rapid increase of human population is putting an incredible strain on our environment. While developed countries continue to pollute the environment and deplete its resources, developing countries are under increasing pressure to compete economically and their industrial advancements are damaging as well. The demands that this growth places on our global environment are threatening the future of sustainable life on earth. One of the largest environmental effects of human population growth is the problem of global warming. Some scientists fear that global warming will lead to rising sea levels and extreme weather conditions in the future. In order to support the growing population, forests are being destroyed at an alarming rate. Humans also continue to put a great demand on the natural resources of our planet. Many non-renewable resources are being depleted due to the unrestrained use of fuel and energy. Many parts of the world also suffer from a shortage of food and water. The growth of population puts larger demands on our already limited resources. The environment on earth is suffering from the growth of global population. The depletion of resources and biodiversity, the production of waste, and the destroying of natural habitat are serious problems that must be addressed in order to ensure that life on earth will be sustainable throughout the next century.

Stem cells in developing bone that give rise to osteoblasts are called Osteoprogenitor cells.

Osteoprogenitor cells are stem cells found in the developing bone that have the ability to differentiate into osteoblasts, which are the cells responsible for the formation and mineralization of bone tissue.

These cells are crucial for the development and growth of the skeleton and the maintenance of healthy bones throughout life. They also play a role in bone repair and regeneration following injury or disease. By giving rise to osteoblasts, osteoprogenitor cells help to ensure the proper development and maintenance of the skeletal system.

Answer:

True

Explanation:

Cellulose is a carbohydrate, meaning it can be identified as a polysacharide. It is often used by plants in the construction of a cell wall in cells. Meaning it also functions as a structural carbohydrate.

Thus, it can be thought that cellulose is a polysaccharide that functions as a structural carbohydrate.

Explanation:

The tails of the cell membrane are __hydrophobic__ while the phosphate heads are __hydrophilic__.

I hope the following image helps to further explain the answer.

The tails of the cell membrane are hydrophobic while the phosphate heads are hydrophilic. The correct option is B.

The phospholipid bilayer, which forms a stable barrier between two aqueous compartments, is the membrane's fundamental structure. These compartments are the inside and outside of the cell in the case of the plasma membrane.

The cell membrane, also known as the plasma membrane, is found in all cells and serves to separate the cell's interior from the outside environment.

The membrane of the cell is composed of a semipermeable lipid bilayer. The cell membrane controls the transport of materials into and out of the cell.

The heads (phosphate) are polar, whereas the tails (lipid) are non-polar. The heads, which form the outer as well as inner linings, seem to be "hydrophilic" (love water), whereas the tails, which face the cell membrane's interior, are "hydrophobic" (water fearing).

Thus, the correct option is B.

the muscles and organs need a certain level of glucose in the blood to work properly. When the body is missing an enzyme or has a flawed enzyme and is not able to use glycogen the right way, it leads to a condition called glycogen storage disease (GSD). Many different enzymes are used by the body to process glycogen.
