Why did Mendel prevent his plants from self-pollinating? to control the crossing of the traits in order to insure that each plant's offspring would remain identical to the parents to maintain a pure strain so they could not produce offspring

The answer is to control the crossing of the traits.

The idea of preventing plants from self-pollinating is to control the crossing of the traits. If plants were self-pollinating, he could not know if the traits are inherited from the same plant or from the other. By preventing this, he could cross parents with known phenotype and that way learn about crossing process and inheriting process.

The temperature to which a mass of air must cool in order to be saturated is the____?

Correct answer would be Dew Point of Temperature

Dew point of temperature is defined as the temperature at which the air must cool in order to become saturated.

At normal conditions of temperature and pressure, the dew point of temperature will not be more than the air temperature because relative humidity cannot be 100 percent. It the temperature is lower than its dew point, then it is called as supersaturated.

Thus, the correct answer would be Dew point.

Which of the following about the copperhead snake is true? a. The copperhead snake is one of six venomous species in North America. b. Copperhead snakes average 4.5 feet in length. c. Copperhead snakes are not camouflaged. d. Copperhead snakes detect heat given off by potential prey.

Answer;

D. Copperhead snakes detect heat given off by potential prey.

Explanation;

-Copperhead snakes are mobile ambush predators. Mostly, they get their prey by "sit-and-wait ambush", however, they sometimes hunt using their heat-sensing pits to find prey.

-When attacking large prey, copperheads bite the victim, and then release it. They let the venom work, and then track down the prey once it has died. The snakes usually hold smaller prey in their mouths until the victim dies.

Succession occurs because _______. a. organisms gradually change the environment b. climax communities are not possible c. dominant organisms drive out pioneer species d. ecosystems never reach a sustainable point

Correct answer: A) Organisms gradually change the environment

Succession occurs when a disturbance takes place in the environment, it can occur either by the disturbance of minor or major order disturbance.

The major disturbance can be caused due to the natural cause like the volcanic eruption and minor disturbance caused due to a natural or human cause like the forest fire.

Based on the type of disturbance succession is classified into two types of primary and secondary succession.

Primary succession is said to occur when a community or a group of the species evolve from a barren land. The land is fresh and new and no life is found on it.

Example: Succession after the volcanic eruption is said to be primary succession.

Secondary succession is said to occur when the disturbance destroys the whole ecosystem, but still, there is an availability of soil, nutrient, and seed in the ecosystem.

Example: Forest fire

Which statement best summarizes "Save the Coral Reefs”?Coral reefs are a very important component of the ocean’s ecosystem because they support sea life, such as crabs and sea turtles. In fact, over four thousand species depend on the survival of the reefs, which are being destroyed by bleaching. More must be done immediately to save the reefs. Development along the coastal regions has significant negative effects on coral reefs. The reefs are an essential part of the ocean’s ecosystem, and when people build structures on top of them, they are easily damaged because they are so fragile.

Answer;

-Coral reefs are a very important component of the ocean’s ecosystem because they support sea life, such as crabs and sea turtles. In fact, over four thousand species depend on the survival of the reefs, which are being destroyed by bleaching. More must be done immediately to save the reefs.

Explanation;

-Coral reefs are important for many different reasons aside from supposedly containing the most diverse ecosystems on the planet.

-They protect coastlines from the damaging effects of wave action and tropical storms ( they provide a buffer, protecting our coasts from waves, storms, and floods, helping to prevent loss of life, property damage, and erosion) and also provide habitats and shelter for many marine organisms.

Which of the following represents change to an ecosystem brought about by abiotic factors? a. the decrease in plant populations due to a decrease in the available water supply b. the increase in a predator population due to the increase in prey population c. the decrease in plant species due to herd grazing d. the extinction of a plant species due to bacterial infection

The answer is A. Abiotic factors are the non-living parts of a species’ habitat. Examplses of abiotic factors are water, moiuntains, wind, rain, temperatuatres, and etcetera. Abiotic factors are significant in an ecosystem because they affect the biotic factors in that they affect their growth and development of organisms in the ecosystem and also their reproduction.
