Answer: All vertebrates have circulatory systems based on a common plan, and so vertebrate systems show much less variety than do those of invertebrates. Although it is impossible to trace the evolution of the circulatory system by using fossils (because blood vessels do not fossilize as do bones and teeth), it is possible to theorize on its evolution by studying different groups of vertebrates and their developing embryos. Many of the variations from the common plan are related to the different requirements of living in water and on land.

Answer:

Anacharis in High Light produces more mLof oxygen per min than Anacharis in Low Light Anacharis and in Medium  Light.

Explanation:

The increased  light intensity also increases the rate of photosynthetic activity. As photosynthesis occurs, the energy from sunlight, along with CO2 is converted to chemical energy in the form of glucose.

6CO2 + 6H20 + (energy) → C6H12O6 + 6O2

or Carbon dioxide + water = energy (glucose) + oxygen

Photosynthesizing cells in green plants produce oxygen as a waste product. As this process is rate-limited, certain factors may increase the reaction rate. These include:

carbon dioxide concentration

water availability

ambient temperature

light intensity;

Answer:

A) It is composed of a network of moist passageways that permit air to flow from the external environment to the lungs.

Explanation:

The correct statement that describes the RESPIRATORY SYSTEM of human being is option A which states that, It is composed of a network of moist passageways that permit air to flow from the external environment to the lungs.

The sequence of processes leading to the release of energy in living cells is called respiration. The most complex respiratory system is found in mammals ( human beings). This involves the following:

Because human beings are exposed to the atmosphere and have dry body coverings. Gaseous exchange cannot occur through their body surfaces, instead they possess respiratory structures to being dry air in contact with moist surfaces within their bodies. These structures includes:

TRACHEA or the wind pipe channels the air to the lungs. At the thorax, the trachea into two forming the right and left BRONCHI.

The alveoli is where the gaseous exchange takes place. Tiny blood vessels, called capillaries, are closely wrapped around the outside of the alveoli. This enables oxygen to diffuse across the walls of the alveoli into the blood.

Therefore the correct option that describes the RESPIRATORY SYSTEM of human being is A which states that It is composed of a network of moist passageways that permit air to flow from the external environment to the lungs.

Option B is WRONG because human beings are not unicellular organisms like Amoeba where their gaseous exchange organs are cell membrane or body surfaces.

Option C and D are equally wrong because human beings are not simple animals like amphibians that involves in cutaneous (skin) respiration.

Answer:

A few genes produce other molecules that help the cell assemble proteins.

Explanation:

During the process of transcription, the information stored in a gene's DNA is transferred to a similar molecule called RNA (ribonucleic acid) in the cell nucleus. Both RNA and DNA are made up of a chain of nucleotide bases, but they have slightly different chemical properties. The type of RNA that contains the information for making a protein is called messenger RNA (mRNA) because it carries the information, or message, from the DNA out of the nucleus into the cytoplasm.

Answer:

This makes them move faster and further apart and the substance expands. This makes the object's volume increase which changes causes the density to decrease.

When a substance is cooled, the particles lose energy. This makes them move slower and closer together and the substance contracts. This makes the object's volume decrease which changes causes the density to increase.

Explanation:

When an object is heating up its molecules will move faster and expand the object, this means the volume is increasing. Density is equal to mass over volume meaning if the volume is increasing the density will decrease. The opposite is true for when the substance is cooled. Molecules will move slower and the object will contract. The volume will decrease and the density will increase.

Answer:

I'm not 100% sure

Explanation:

Different regions have access to different renewable or nonrenewable natural resources such as freshwater, fossil fuels, fertile soil, or timber based on their geographic location and past geologic processes. Access, or the lack thereof, contributes to a place’s economic development, political relationships, and culture. For example, the Great Plains region of the United States is known for its abundance of fertile soil. As a result, its main industry is agriculture. Corn, soybeans, and wheat are globally exported from this region and serve as the main economy. On the other side of the spectrum, the desert southwestern region of the United States depends on the Central Arizona Project canals to transport water from the Colorado River in order to support agriculture and urban areas. Arizona’s right to use water from this river stems from the Colorado Compact, an agreement established in 1922.

Answer:

Evaporation, Condensation, Precipitation, Surface Runoff

Explanation:

Evaporation: Water turns into gas and goes into the clouds.

Condensation: Water vapor in the air is changed into liquid water.

Precipitation: Water leaves the cloud as rain, hail, or snow.

Surface Runoff: Water left on land after it rains.

       The green sea turtle, also known as the green turtle, black turtle, or Pacific green turtle, is a species of large sea turtle found in warm subtropical and tropical ocean waters.  The green sea turtle is an endangered species and its population number decreases every year.  Recent estimates show us that there are 1.5 million green sea turtles worldwide, and only 300,000 remaining in the Caribbean.  Researchers estimate that 4,600 green sea turtles perish each year because of fishing gear, poachers, vessel strikes, loss of foraging habitat, entanglement in or ingestion of marine debris, and the harvesting of their eggs.  We can stop the green sea turtles from going extinct by making fishing gear safe for the turtles, staying away from their nesting areas, protect them from poachers, stop the harvesting of their eggs, and keeping the oceans and beaches clean so there is nothing to strangle or poison them.  These are just a few ways people can help save the green sea turtles from going extinct.

Answer and Explanation:

I think the dewpoint is 11.09°C or 11.1°C. I'm not sure though..

let me know if I'm wrong..

The dew point temperature is at 11.62°C for a relative humidity of 64%

The dew point is the temperature the air needs to be cooled to (at constant pressure)

Given that:

Relative humidity (R) = 64%, Dry-bulb temperature(T) = 18 °C.

The dew point (D) is:

[tex]D=\frac{237.3*B}{1-B} =\frac{237.4*0.0467}{1-0.0467} =11.62[/tex]

The dew point temperature is at 11.62°C for a relative humidity of 64%
