1) Read the following paragraph and answer the following questions.
The countries which do not have oil reservoirs in their land, import oil from other countries. But sometimes during transportation of oil through sea routes, accidental oil spill occurs. This oil spilled in the ocean may prove fatal and toxic to aquatic animals. Therefore, removal of this spilled oil is essential for protection of aquatic life. For removing this oil layer, certain microbes like Pseudomonas spp and Alcanivorax borkumensis are used. These microbes have the ability to destroy the pyridines and other toxic chemicals. The hydrocarbonoclastic bacteria (HCB) are able to decompose the hydrocarbons and bring about the reaction of carbons with oxygen resulting in formation of CO2 and water. Like oil spills cause damage
to aquatic life, plastic forms the major part of the garbage on the land. Plastics are difficult to degrade as they are made up of PET, by research various species like Vibrio and Ideonella sakaiensis which can degrade PET have been identified. There are certain species of microbes which can decompose rubber from garbage.
a) How are aquatic organisms affected by oil spills in the ocean?
b) Which type of chemical compounds are degraded by microbes used for
clearing oil spills?
c) Name any two species of microbes which can degrade rubber from
garbage.
d) Why should there be a ban on plastic bags?
Answer: See explanation
Explanation:
a) How are aquatic organisms affected by oil spills in the ocean?
Aquatic organisms are affected by oil spilled as it is fatal and toxic to them. It can cause death, habitat degradation, vulnerability to predators and can also lead to the inability to hatch their eggs.
b) Which type of chemical compounds are degraded by microbes used for
clearing oil spills?
The chemical compound degraded by microbes are clearing oil spills are Pseudomonas spp and Alcanivorax borkumensis.
c) Name any two species of microbes which can degrade rubber from
garbage.
These are Vibrio and Ideonella sakaiensis.
d) Why should there be a ban on plastic bags?
There should be a ban on plastic bags as they're difficult to degrade as they are made up of PET.

How do toothed whales produce echolocating sounds?
Answer:
Toothed whales (including dolphins) have developed a remarkable sensory ability used for locating food and for navigation underwater called echolocation. Toothed whales produce a variety of sounds by moving air between air-spaces or sinuses in the head.
Explanation:
Answer:
Toothed whales can direct sound by bouncing it off air sacs in their nose and possibly by using face muscles to alter the shape of the melon.

Which of the following is NOT an example of evidence that supports the theory of evolution?
A. common genetic ancestors among diverse species
B. fossil evidence suggesting ancient genetic ancestors
C. unnecessary or nonfunctional organs in modern species
D. fossils of the same species found diverse geographic locations
The statement that is not an example of evidence that supports the theory of evolution is fossils of the same species found in diverse geographic locations.
What do you mean by Evolution?Evolution may be defined as a gradual and continuous process that runs over many generations, during which species of animals, plants, or insects slowly change some of their physical characteristics.
Common genetic ancestors may be diverse into the number of other species due to the theory of evolution. Unnecessary or non-functional organs may be eliminated or shortened due to evolution.
Therefore, the statement that is not an example of evidence that supports the theory of evolution is fossils of the same species found in diverse geographic locations.

Why do the different genetic types of albinism result in a similar phenotype?
Answer:
Why are there different variations of albinism and why it results in the same basic phenotype?
The phenotypic heterogeneity of albinism is due to the different gene mutations affecting various points along the melanin pathway, resulting in varying degrees of decreased melanin production. Additionally, associated developmental changes occur in the optic system as a result from this hypopigmentation.

How are the different parts of the plant reproductive system function to carry out sexual reproduction?The stamen is composed of anthers and filaments and is responsible for making the male gamete. The pistil is the female reproductive part of the flower and it is divided into three parts namely stigma, ovary, and style. It produces the female gamete. The primary function of the flower involves the production of male and female gametes and it carries out the process of sexual reproduction in plants.
The process of meiosis is used to produce the gametes. It occurs in the anther and ovary which are the reproductive parts of the plant. Fertilization takes place in the ovary in plants.

Why would allowing a plant to undergo photosynthesis 24 hours a day cause it to grow faster?
Compared to freshwater fishes, marine fishes: drink seawater and produce a large volume of urine. do not drink seawater in an effort to conserve as much water as possible. produce a large volume of dilute urine in an effort to rid their bodies of excess water. tend to gain water by osmosis since their internal salt concentration is higher than that of seawater. tend to lose water by osmosis since their internal salt concentration is lower than that of seawater.
Answer:
The correct answer is - tend to lose water by osmosis since their internal salt concentration is lower than that of seawater.
Explanation:
In freshwater fishes, the body of fishes has a higher salt concentration inside their body than the surrounding water, water enters through the osmosis process. Without any active regulation of this process, fishes would swell and get bigger and bigger. They have specialized cells called chloride cells in gills to take ions from water as they do not have kidneys.
In contrast, the marine fishes have a lower salt concentration in their body than surrounding water of sea or ocean and they lose water continuously and to compensate for this they need to drink water regularly.
