Answer:
Ultramafic rocks contain olivine and are commonly found in mantle.
Explanation:
Ultramafic rocks are a type of ignea rock that are found in the mantle. These rocks have a very low silica content, but have olivine and a high iron content. They are also low in potassium and sodium. The mantle is basically composed of this type of rocks, but they can be seen on the surface in the form of Ophiolitic complexes.

Which of the following statements about the economy of Eritrea after independence is false?
A.
The population and economy of Eritrea face agricultural problems brought on by climate issues.
B.
Nearly 80% of Eritrea's population is employed in the industrial sector.
C.
Eritrea has a command economy.
D.
Eritrea is struggling with costly property damage caused by war.
Answer:
B. Nearly 80% of Eritrea's population is employed in the industrial sector.
Explanation:
The economy of Eritrea, after the independence, and currently, is primarily based on the service sectors, with industry and agriculture being a lot less important, and less productive for the economy as a whole. Thus, it is false to state that nearly 80% of the population of Eritrea is employed in industry.

The tiny fruit fly is a superstar of genetics research. Thousands of experiments have explored how flies inherit traits. Wing shape, body color, eye color, and head shape are a few traits under investigation. Fruit flies make good study subjects because they are inexpensive, take little space, and breed quickly. In addition, humans and fruit flies share 75% of their disease genes. By studying fruit-fly genetics, we can learn about human illness.
Short-winged fruit flies studied in the lab cannot fly because they have an allele that causes them to grow tiny wings (w). Normal fruit flies, known as “wild-types”, have fully functional wings (W). The wild-type wing is the dominant allele.
If you cross one short-winged fly (ww) with a wild-type fly (WW), what is the probability of getting a short-winged offspring in the F1 generation?
Explain your reasoning.
Answer:
a. 0
b. There are no short winged genes expressed in this generation
Explanation:
a. What is the probability of getting a short-winged offspring in the F1 generation?
Since we have the ww gene for the short winged fly and the WW gene for the wild type fly.
In the F1 generation, we have
Ww, Ww, Ww and Ww
Since the W wild-type allele is the dominant gene, in the F1 generation, all the fruit flies have wild-type wing.
Probability of short-winged fly, P(short-winged) = number of short-winged genes/total number of genes =
number of short-winged genes = 0
total number of genes = 4
P(short-winged) = 0/4 = 0
b. Explain your reasoning.
Since the wild winged type allele is the dominant gene, there are no short winged genes expressed in this generation. Thus, the probability of obtaining a short-winged fly in the F1 generation is therefore zero.

Anti-whaling activists argue that the number
of whales hunted by the Japanese each year is unsustainable. What does this mean?
Answer:
The statement means that the number of whales hunted is so large that it is impossible or hard to get it back to normal or tolerate the extent of the reduction in the whale population.
Explanation:
The term "unsustainable" means something that is not bearable, viable, acceptable, tolerable, renewable, etc. This means that an issue cannot be replaced or refilled easily.
In the context of the whaling industry in Japan, the anti-whaling activists expressed the "unsustainable" nature of the extent to which the Asian nation hunted and killed whales. In arguing that "the number of whales hunted by the Japanese each year is unsustainable", they mean to emphasize the large extent to which the whales were killed and the difficulty in replacing or tolerate the act. In short, the activists' argument means that the number of whales hunted will be impossible to regain or filled, or even accepted.

Over time, the movement of people on Earth has steadily increased. This has altered the course of human evolution by increasing gene flow. Thus option last is correct.
What is Earth?Earth is a planet present in the solar system having the existence of life. This is the only planet on which life is possible due to living conditions that ensure the availability of water which is important for survival.
The process of evolution is how communities of organisms evolve through time. These alterations are caused by genetic differences. Divergent, coevolution, parallel, and convergent evolution are among the various forms of evolution.
An individual's chromosomes can enter or leave a group through "gene flow." It involves the transfer of genetic material from one population of a species to another, transforming the composition of the recipient population's gene pool.
Therefore, option last is appropriate.

Help!! 3. Provide a simple explanation for nuclear fusion' and describe how this process produces
energy.
Answer:
Two nuclei form into one nuclei.
Explanation:
Nuclear fusion is a type of reaction in which two atomic nuclei are combined to form one atomic nuclei and subatomic particles i.e. neutrons or protons with the release of energy. In nuclear fusion reaction, some amount of reactant transform into a new atom because the mass of reactant is higher than the single atom while the remaining amount of reactant transform into energy. This reaction occurs in the sun which provides energy to the whole universe.

Which of the following statements is true? Group of answer choices Temperature inversions make pollution problems worse. Normally, cool air near earth's surface expands and rises, carrying pollutants higher into the troposphere. Temperature inversions help prevent air pollution. Temperature inversion occurs when a layer of cold air prevents warm air from rising.
Answer:
Normally, cool air near earth's surface expands and rises, carrying pollutants higher into the troposphere.
Explanation:
Thermal inversion is an atmospheric phenomenon. It tends to occur in large urban centers where industrial production is intense and the amount of polluting gases is greater. When the thermal inversion happens, the cold air is trapped and is prevented from circulating. This cold air is trapped close to the Earth's surface, very close to the toposphere. The problem is that cold air is loaded with polluting gases and this promotes strong atmospheric pollution, which aggravates many environmental and health problems. It is because of the thermal inversion that we can see a gray layer on the horizon of some urban centers.
