Why are invasive species dangerous to the environment?
A)They pollute the environment.
B)They are always predators.
C)They threaten biodiversity.
D)They bring abiotic factors.
Answers
Answer:
C
Explanation:
They threaten the other animals. They can take their food, homes, and they don't have natural predators.
Invasive species are dangerous to the environment as they threaten the biodiversity. Thus, the correct option is C.
Invasive species are those imported species that are able to thrive rapidly in another foreign area by adapting and reproducing quickly.
Invasive species of plants and animals lead to an increase in the competition for survival, which results in decrease in the population of the native species.
The invasive species also affect the food web that is existing in the particular ecosystem, because of which other all organisms which are part of the food web are affected. They outcompete the native species for food,
Thus, biodiversity is threatened due to the invasive species.

A rich variety of genetic material in an ecosystem will increase the chances that some organisms will survive change.
What is an ecosystem?An ecosystem contains all the organisms and the biological environment (which contain abiotic and biotic factors ) with which they show interaction.
These biotic and abiotic components are related concurrently through nutrient and water cycles and energy discharges.
Energy joins the procedure through photosynthesis and is interspersed into plant tissue.

These chemical reactions produce waste products such as carbon dioxide, water, salts, urea and uric acid. Accumulation of these wastes beyond a level inside the body is harmful to the body. The excretory organs remove these wastes. This process of removal of metabolic waste from the body is known as excretion.

Morphological distinction is one of the steps necessary for speciation to occur.
What are the other two?
Answers
Answer:
Genetic Separation / Geographic isolation
Explanation:
Morphological distinction (or phenotypic differentiation) can be defined as the diversification of a set of observable physical characteristics in a population, capable of differentiating certain species.
The genetic separation occurs when the division of a group of genes into two or more pools of genes separated over time and depending on several other situational factors.
Geographic isolation occurs due to the physical separation of subpopulations of a given species. The barriers that isolate these subpopulations can be, for example, a river that cuts through a plain, a valley that divides plateaus or a portion of the sea that separates islands and continents.

The amusement park will be located in a hot climate. The engineers want to select a material for the giant slide that will prevent the surface from getting too hot. Based on the specific heat values, what material would be the best choice? A.Plastic, because it takes more energy to raise its temperature B.Iron, because it takes more energy to raise its temperature C.Plastic, because it takes less energy to raise its temperature D.Iron, because it less energy to raise its temperature
Answers
Answer:
A
Explanation:
The correct answer would be plastic because it takes more energy to raise its temperature.
The specific heat capacity of a substance is the amount of heat required to raise the temperature of the substance by one degree. The more the specific heat capacity of a substance, the more the heat required to raise its temperature.
The specific heat capacity of plastics is generally more than that of metals. Hence, metals will get heated faster than plastics under the same condition. More energy would be needed to raise the temperature of plastics when compared to metals.
the correct option is A.

For her science fair project, your little sister replicated one of Mendel's experiments. From a P0 pea plant with purple flowers and a pea plant with white flowers, she got 1 purple F1 hybrid (she had forgotten to water, so just one survived). From this self-fertilized F1 she got 8 F2 offspring. 7 were purple and 1 was white, for a 7:1 ratio. Did your little sister just disprove Mendel's laws
Answers
Answer: No, the 7:1 ratio is close to the expected 6:2 ratio even with the limited sample size.
Explanation:
Let the alleles be P (purple) and W (white).
The possible crosses are
PP x WW, PP x PW, PW x WW, PW x PW
the F1 is PP or PW
one F2 is white so the F1 must be PW and
the F2 are PP, WW, PW and
the expected 8 progeny are 2PP, 2WW, 4PW
Because 7/8 are purple, we can infer that P is dominant and W recessive, so the expectation is 6 purple, 2 white
The observed ratio is similar to the expected ratio, so we can’t say that this result disproves Mendel, particularly with a small sample.
7:1 is close to 6:2, even if the sample is smaller. We cannot invalidate Mendel with such a small sample size because the observed ratio was not statistically different from the anticipated ratio.
What is Mendelian Ratio?The term "Mendelian inheritance" refers to specific patterns that can be observed in the way characteristics are passed down from parents to children. In the 19th century, the Austrian monk Gregor Mendel conducted thousands of tests with pea plants in order to develop these broad patterns. He did this in order to determine the genetic makeup of pea plants.
The frequency with which diverse phenotypes are produced as a result of any cross incorporating Mendelian traits. in particular, the three to one ratio that is displayed by the second generation of descendants from parents who are different from one another in regard to a single character.
