Answer:
Acetone
Explanation:
Answer: Acetone.
Explanation: Acetone molecules have a polar carbonyl group that allows them to ACCEPT hydrogen bonds from OTHER compounds. The slightly positive charge on each hydrogen can attract slightly negative oxygen atoms on other water molecules, forming hydrogen bonds. If acetone is added to water, acetone would completely dissolve.

Answer:
B
Explanation:
Decommissioned oil rigs are sometimes converted to artificial reefs in the Gulf of Mexico. What is the likely impact to the ecosystem by creating artificial reefs around these retired oil rigs?
a
The large fish population will increase, but the small fish population will decrease.
b
Biodiversity is increased throughout the ecosystem.
c
Biodiversity remains the same because organisms do not like man-made structures
d
Invasive species of fish move into the ecosystem because there are no natural predators.
Answer:
B
Explanation:
B
The likely impact on the ecosystem by creating artificial reefs is that biodiversity would be increased throughout the ecosystem (Option B).
What is biodiversity?The term biodiversity makes reference to all types of forms of life (organisms) present in a given ecosystem.
Biodiversity can also be used to explain the genetic and phenotypic variation in a population.The loss of biodiversity may have drastic consequences on the whole ecosystem.In conclusion, the likely impact on the ecosystem by creating artificial reefs is that biodiversity would be increased throughout the ecosystem (Option B).

List two advantages for synthetic fertilizers
Answer:
Cheaper to purchase than organic
Nutrients are concentrated, only small amounts needed
Nutrients are quickly available for plant absorption
Answer:
They're faster acting than organic making them a good choice for aiding plants in severe distress from nutrient deficiencies. These fertilizers, which come as dry, granular pellets or water-soluble products, also provide even, consistent feeding.

Answer:
Most often there is a unicellular alga chlamydomonas. It moves in water with the help of two flagella located on the front, narrower end of the cell. Outside the chlamydomonas is covered with a transparent membrane, under which there is a cytoplasm with a nucleus, a red "eye" (a photosensitive body of red color), a large vacuole filled with cell juice, and two small pulsating vacuoles. Chlorophyll, contained in the chromatophores, gives a green the cell a green color.

Describe the order of succession for the regrowth of
the fire destroyed forest.
Explanation:
Primary succession is one of two types of biological and ecological succession of plant life, occurring in an environment in which new substrate devoid of vegetation and other organisms usually lacking soil, such as a lava flow or area left from retreated glacier, is deposited.[1] In other words, it is the gradual growth of an ecosystem over a longer period of time.[2][3]
Primary succession occurring over time. The soil depths increase with respect to the increase in decomposition of organic matter. and there is a gradual increase of species diversity in the ecosystem. The labels I-VII represent the different stages of primary succession. I-bare rocks, II-pioneers (mosses, lichen, algae, fungi), III-annual herbaceous plants, IV-perennial herbaceous plants and grasses, V-shrubs, VI-shade intolerant trees, VII-shade tolerant trees.
Primary succession on Rangitoto Island
In contrast, secondary succession occurs on substrate that previously supported vegetation before an ecological disturbance from smaller things like floods, hurricanes, tornadoes, and fires which destroyed the plant life.[4]

Two short-haired guinea pigs are mated several times. Out of 100 offspring, 25 of them have long hair. What are the probable genotypes of the parents? Show the Punnett Square to prove it.
Answer:
Ss (male) × Ss (female)
Explanation:
This question involves a single gene coding for hair length in guinea pigs. Based on the information in this question, the allele for short hair (S) is dominant over the allele for long hair (s). This means that a guinea pig will only be phenotypically long-haired if the genotype is "ss".
According to this question, Two short-haired guinea pigs are mated several times. Out of the 100 offsprings produced by this cross, 25 of them have long hair (recessive). This means that the phenotypic ratio of this cross is 3 short hair : 1 long hair i.e. 100 - 25 = 75 short hair. 75/25 = 3/1 = 3:1
To produce this phenotypic ratio, the parents must both be heterozygous (Ss) for the hair length gene.

Which of the following best describes the matter present in an ecosystem?
A.
New matter is continuously generated by an ecosystem in a process known as photosynthesis.
B.
The waste materials generated by one organism are often reused by other organisms.
C.
The total amount of matter in an ecosystem is constantly decreasing due to the process of decomposition.
D.
When an organism reproduces, new matter is added to its ecosystem.
Answer:
D
Explanation:
When an organism reproduces, new matter is added to its ecosystem, is the correct answer.
Answer: It's is the second one. The waste materials generated by one organism are often reused by other organisms.
Explanation: Mass, or matter, is conserved in all physical and chemical changes. Matter is not created or destroyed within ecosystems, it only undergoes physical or chemical changes. One example of this process is that the waste materials generated by one organism are often reused by other organisms as food or nutrients.
