Answer:B
Explanation:
The study on zooplankton contribute to the development of ideas in the text as It reveals that some marine creatures can break down plastic particles.
What are planktons?Planktons are the organisms that are found in an aquatic habitat which has been serve as the source of the food to the larger animals and humans. There are two major types of Plankton which are known as the phytoplankton and Zooplankton. The Zooplankton are those planktons that has animal-like features. The main examples of zooplanktons are jelly fish,chordates and amphipods.
Their size is from 1 millimeters and above (within a range of 20 - 200mm) unlike microplankton that is less than 1mm in size. The jelly is a typical example of a macroplankton. Plastic contains hazardous toxins that harm the ecosystem and pollute the land, water, and air. "Plastic should not be used near rivers," one person believes.
Therefore, the zooplanktons are also divided into two namely the macroplankton and the microplankton.

For a certain breed of cat, short tails are dominant (T) and long tails are
recessive (t). The Punnett square below shows a cross between two parents.
What is the phenotype ratio for this cross?
O A. O long, 4 short
O B. 4 long, 0 short
C. 2 long, 2 short
D. 3 long, 1 short
The phenotype ratio for this crosse accurate solution is -
The phenotypic ratio for this move is 3:1 (quick tail: lengthy-tail).
As in step with the statistics withinside the question, the quick tail of a cat (depicted via way of means of T allele) is a dominant trait over lengthy tails of cat (depicted via way of means of t allele), that is a recessive allele.A dominant trait continually masks the expression of a recessive trait.There may be a feasible genotypes for quick tails, which are 'TT' and 'Tt'.On the opposite hand, there may be the handiest one feasible genotype for lengthy tail, that is 'tt'.What is phenotype?
The term "phenotype" refers back to the observable bodily residences of an organism; those encompass the organism's appearance, development, and behavior. An organism's phenotype is decided via way of means of its genotype, that's the set of genes the organism carries, in addition to via way of means of environmental affects upon those genes.
Thus, from the given move, we will finish that the phenotypic ratio, representing the bodily look of the tail that is brief and lengthy tails is 3:1 (quick tails: lengthy tails).

Four hundred beetles of the same species were sprayed with an insecticide. Several weeks later, nearly all the beetles were dead. A few, however, survived. Which statement best describes the future generations of these beetles?
Answer:
................ ....
Future generations of beetles will likely survive the insecticide if it is sprayed again because gene resistance would pass to the next generation. Hence, option D is correct.
What is gene resistance?Microbes develop defense mechanisms against the effects of antibiotics, which leads to the development of antimicrobial resistance. Microbes of all types can develop resistance. Infection-resistant fungi develop. Antiviral resistance among viruses develops.
Once a bacteria have acquired a resistance gene and incorporated it into its DNA, the bacterium can dominate other bacteria and convey the resistance gene to all of its offspring. Bacteria reproduce quickly, which amplifies resistance.
Future generations of beetles will likely survive the insecticide if it is sprayed again. Hence, option D is correct.

NASA scientists use satellites to monitor two important factors that lead too landslides
Answer:
The most important factors that lead to landslides are the declivity of the terrain and the type of soil.
Explanation:
Stony soils are more prone to landslides, especially on steep terrain and without any type of vegetation cover. During heavy rainfall, these two factors can promote landslides that cause major disasters, as water is able to drag this soil violently. To prevent this from happening and people from being harmed, NASA has developed satellites, which capture rainfall data and monitor the slope and composition of soils, being able to see in advance areas that could be landslides. In this way, it is possible to develop strategies that prevent the landslide from happening.

Track the evolutionary path of a butterfly and comment on it.
Answer:
The colorful canvas of the butterfly wing is an example of evolutionary innovation and adaptation. Compared with their ansestors, whose wings wore patterns of black, brown, and gray, the Lepidoptera (butterflies and moths) evolved a more varied palette of pigmentation.
I think it is very cool that they were able to evolve. For example, some butterflies use their bright colors to trick preators into thinking they are poisonous. The early butterflies could not do this.

Walking sticks are insects that may have either a striped body or a body without stripes. In one region where these walking sticks live, the vegetation is a plant with needle-like leaves that resemble the walking stick’s striped body. According to natural selection, what would most likely result from an increase in walking stick predators in the region? (SC.7.L.15.2) A.walking sticks without stripes will reproduce faster B.walking sticks with stripes will become more common C.walking sticks will develop a new, spotted pattern for their bodies D.walking sticks will live on rare plant species rather than the dominant species
Answer:
B. Walking sticks with stripes will become more common.
Explanation:
The striped bodies of the walking sticks will help them camouflage in the plants. The predators will be more likely to kill off the unstriped walking sticks, leaving the striped walking sticks to grow in population and become more common.
