Which layer of Earth is made up partly of crust and partly of Mantle material?

Answer:

When properly stimulated, electrons in these materials move from a lower level of energy up to a higher level of energy and occupy a different orbital. Then, at some point, these higher energy electrons give up their "extra" energy in the form of a photon of light, and fall back down to their original energy level.

Answer:

The young man is not the son of Howard Hughes.

Explanation:

The human blood system works on codominance type of inheritance in the case of blood group A and blood group B present together however, in blood group O it still follows the law of dominance as antigen O is recessive in present of any other antigen.

We know Howard Hughes had blood type AB

So, the genotype would be - IAIB

We also know that the mother of the young man claiming has a blood type A

So, possible genotypes would be - IAIA (case 1) or IAi (case 2)

For case 1,

The possible genotypes for the man claiming would be

IAIB X IAIA --------> IA IA, and IAIB.

According to case 1, he is not the son of Howard.

For case 2,

The possible genotypes for the man claiming would be

IAIB. X I A i ---------> IA IA , IAIB   I A i and IB i

Both cases show that the man claiming is not the son of Howard as the blood group of the man is O and the genotype should be ii.

Answer:

habitat destruction, unpredictable precipitation, and freeing temperatures.

Explanation:

i took the quiz

The destruction of the habitat, unpredictable precipitation, and freezing temperatures decreases biodiversity. Thus, options a, b, and d are correct.

Biodiversity is the variety of life that sustains on earth and lives in a particular habitat. The biodiversity can be measured based on the ecosystem, species, and genetics. It comprises the ecological and evolutionary process.

The destruction of the habitat of a species can lead to a decrease in biodiversity as it affects the ecosystem and the ecological pyramid as a whole and will affect the population of the species.

The unpredictable precipitation can affect the species and the habitat as it may lead to floods that will destroy the habitat hence resulting in the loss of species.

Similarly, the decrease in temperature will affect many species as they will not be able to cope with low temperature resulting in their death.

Therefore, the unpredictable precipitation, freezing temperature, and destruction of habitat lead to a decrease in biodiversity.

Answer and Explanation:

Engine irrigation pumps are used to propel water into the irrigation channels, providing full water supply to agricultural crops. The use of the engine pump has advantages and disadvantages. Among the advantages, we can present the simplicity of operation of these pumps, being easily operated efficiently. They also save energy and are essential for irrigation with more viscous liquids, when necessary. This feature is the main reason for using this type of pump.

Among the disadvantages we can say that these pumps have a slower and less accurate work.

When a barometer is supplied with a nonlinear calibration so as to indicate altitude, the instrument is called a pressure altimeter or barometric altimete

Explanation:

Altimeters

An altimeter is a device that measures altitude, the distance of a point above sea level. Altimeters are important navigation instruments for aircraft and spacecraft pilots who monitor their height above the Earth's surface.

Answer:

•100%

Explanation:

Mitosis is a type of cell division which results in two daughter cells that are genetically identical to the original or parent cell. The identical nature of the daughter cells to the parent cell means that the number/amount of genetic material is maintained in the cells i.e. a diploid (2n) cell with 10 chromosomes will undergo mitosis to produce two diploid (2n) daughter cells with 10 chromosomes each.

Based on the explanation above, at the end of mitosis, 100% of the original cell's genetic information (DNA) can now be found in each daughter cell. Note that, this is contrary in meiosis, which reduces the genetic content by half.

Answer: Red blood cells carry oxygen from our lungs to the rest of our bodies. Then they make the return trip, taking carbon dioxide back to our lungs to be exhaled. The function of the red cell and its hemoglobin is to carry oxygen from the lungs or gills to all the body tissues and to carry carbon dioxide, a waste product of metabolism, to the lungs, where it is excreted.

Gravity is not the same thing as magnetism. They are in fact entirely distinct forces. Gravity is a force that works with weight between two objects. Magnetism can pull or separate the two objects, depending on how the magnets point.

Explanation:

Answer:

allopatric speciation.

Explanation:

Reproduction can be defined as a biological process which typically involves living organisms producing an offspring.

Basically, there are two (2) methods of reproduction and these are;

I. Sexual reproduction.

II. Asexual reproduction.

In this scenario, a freshwater snail species is divided into two (2) large isolated populations by a mountain range. This range is then lowered by an erosion and as such bringing the two populations of the freshwater snail species together again.

However, when the two snail species mate, the resulting hybrids all produce sterile young snails. Thus, this scenario is an example of allopatric speciation.

Allopatric speciation is also referred to as geographical speciation and it can be defined as a process in which two (2) biological populations of the same species become isolated from each other by geographical barriers or changes such as mountain range, emigration, etc. Thus, allopatric speciation is dominant with living organisms that reproduces sexually and it causes the isolated species to evolve newly with distinctive traits.

Answer:

Incomplete dominance is when the phenotypes of the two parents blend together to create a new phenotype for their offspring.

An example is a white flower and a red flower producing pink flowers. Codominance is when the two parent phenotypes are expressed together in the offspring

The correct answer is 4. They convert salt and iron into energy and nutrients.

Explanation

Xenophiophores are large single-celled organisms generally found deep in the deep sea. They are characterized by being very delicate organisms, which makes it difficult for scientists who intend to study them since they are easily damaged by manipulation. However, in the studies that have been carried out on these organisms, it has been found that they are irreplaceable agents in the sediment deposition process and the maintenance of the biological diversity of benthic organisms. Also, it has been shown that in the areas where these organisms are found there are three to four times more benthic crustaceans, echinoderms, and mollusks than the equivalent areas not inhabited by these organisms. On the other hand, none of these studies has proven that They convert salt and iron into energy and nutrients. Therefore, the correct answer is 4. They convert salt and iron into energy and nutrients.

Answer:

Nondisjunction during sperm arrangement and formation brought about her getting no sex-chromosome from her dad and an X chromosome from her mom, she is XO.

Explanation:

Nondisjunction during sperm arrangement and formation brought about her getting no sex-chromosome from her dad and an X chromosome from her mom; she is XO.  

It is on the grounds that her mother happens to be a carrier of hemophilia and she transferred that mutant allele to her daughter and due to the fact that she did not get any sex-chromosome from her dad.

However, such mutant (X) communicates and expresses itself and she is hemophilic.

This (X) is not express in her mother because she possesses a recessive trait; as such it appears in the hom8zygous state.

Explanation:

Scientists have predicted that long-term effects of climate change will include a decrease in sea ice and an increase in permafrost thawing, an increase in heat waves and heavy precipitation, and decreased water resources in semi-arid regions.

Below are some of the regional impacts of global change forecast by the Intergovernmental Panel on Climate Change:

North America: Decreasing snowpack in the western mountains; 5-20 percent increase in yields of rain-fed agriculture in some regions; increased frequency, intensity and duration of heat waves in cities that currently experience them.

Latin America: Gradual replacement of tropical forest by savannah in eastern Amazonia; risk of significant biodiversity loss through species extinction in many tropical areas; significant changes in water availability for human consumption, agriculture and energy generation.

Europe: Increased risk of inland flash floods; more frequent coastal flooding and increased erosion from storms and sea level rise; glacial retreat in mountainous areas; reduced snow cover and winter tourism; extensive species losses; reductions of crop productivity in southern Europe.

Africa: By 2020, between 75 and 250 million people are projected to be exposed to increased water stress; yields from rain-fed agriculture could be reduced by up to 50 percent in some regions by 2020; agricultural production, including access to food, may be severely compromised.

Asia: Freshwater availability projected to decrease in Central, South, East and Southeast Asia by the 2050s; coastal areas will be at risk due to increased flooding; death rate from disease associated with floods and droughts expected to rise in some regions
