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.

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.

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.

Answer:

they should have 46 chromosomes

Answer:

l

Explanation:

When an organism or insect develops a mechanism for the removal of the pesticide compound is known as pesticide resistance.

The organism or insects develop mechanisms such as the alternation of the binding site of the compound present in the pesticide leading to the development of resistance against the used pesticides. The development of resistance against the pesticide is a slow process, it takes time. The usage of pesticides becomes a failure if organisms develop resistance.

The frequent use of pesticide and insecticides cause changes in the genetic material of the organisms. They help in the development of enzymes and changes in the binding sites. These changes are passed on to the next generation of the organism, which makes the entire population resistant to the particular pesticide and insecticide.

The use of the chemicals should be monitored. Only use when required with rotation.

Answer:

The female part of the flower is called gynoecium or pistil

Explanation:

The female part of a flower is called the gynoecium or pistil. The pistil is located in the center of the flower and consists of three parts: the stigma, style, and ovary.

The stigma is a sticky knob-like structure located  at the top of the pistil. It is covered with a sticky substance so pollen grains will stick to it. It is attached to the long, tubelike structure called the style.

The style is a long  long tubelike structure which connects the stigma to the ovary. The style provides the pathway through which the pollen grains will travel to the ovary in order to fertilize the eggs or ovule

The ovary is the enlarged portion of the pistil found at the base of the pistil. It contains the eggs or ovules.  After fertilization, the ovary develops into the fruit and the ovules become seeds. Based on where the ovary of a plant is located, a plant can be classified as having a superior ovary, an inferior ovary or a half-inferior ovary.

Answer:

Metabolism is the chemical reactions that take place inside a living organism. The reaction occurs in the cells.  Digestion can be the best association to metabolism. The metabolic system recognizes which substances can be nutritious or poisonous. In order to complete this process, water is needed.  The chemicals are dissolved in water and transported. Without water, no reaction can take place.

Metabolism is considered as the set of life-sustaining chemical reactions within the living organism’s body cells.

Answer:

For Gregor Mendel, pea plants were fundamental in allowing him to understand the means by which traits are inherited between parent and offspring. He chose pea plants because they were easy to grow, could be bred rapidly, and had several observable characteristics, like petal color and pea color.

Explanation:

Gregor Mendel chose the pea plants for his experiments because the garden pea is an ideal subject in the study of genetics for the following reasons: The presence of observable traits with contrasting forms. It produces many offspring in one cross. Short life cycle.

Solution: Pea plants were chosen for Mendel's experiments because they are easy to grow, have a short life period, and produce larger flowers. Pea plants are also self-pollinated.

Gregor Mendel describes his experiments with peas showing that heredity is transmitted in discrete units. From the earliest time, people noticed the resemblance between parents and offspring, among animals and plants as well as in human families. Gregor Johann Mendel turned the study of heredity into a science.
