Which combination of alleles best describes a sex-linked trait? A. heterozygous alleles
B. homozygous alleles
C. alleles that are carried on X and Y chromosomes
D. alleles that are carried on somatic cells

Answers

Answer 1

Answer: B. homozygous alleles

Each human body is composed of genes, and these usually come in pairs that are slightly different from each other. The different versions of genes are called alleles. Alleles are responsible for determining physical or notable characteristics and traits a specific person has.

The food web above represents feeding relationships in a biological community near a deep-sea hydrothermal vent. Hydrothermal vents are geysers on the seafloor that gush super-heated, mineral-rich water. The seawater surrounding hydrothermal vents typically contains carbon dioxide (CO2), molecular hydrogen (H2), hydrogen sulfide (H2S), and methane (CH4). Sunlight, however, fails to reach the seafloor where deep-sea hydrothermal vents are located.As part of an investigation, researchers collected living specimens from an area near a deep-sea hydrothermal vent. Mussels in the collection were found to be dependent on molecular hydrogen in seawater. Also, the researchers discovered multiple species of bacteria living in the gills of the mussels. Mussels use gills for filter-feeding and gas exchange with the surrounding seawater. On the basis of their experimental results, the researchers hypothesized that some bacteria living in the gills of the mussels are capable of chemosynthesis. Based on an analysis of the food web, an observation that deep-sea bacteria consume molecular hydrogen (H2) is most relevant to resolving which of the following apparent contradictions?Some organisms rely on energy captured from inorganic compounds to drive basic biological processes.Some deep-sea organisms appear to be primary consumers, but no plants live near the hydrothermal vents.

What is the difference between membrane distillation and pervaporation?

Answers

The pervaporation process is a relatively new, having common elements, reverse osmosis and gas permeation . The separating liquid mixtures by pervaporation difference in vapor pressure between the feed and the permeate. This difference in vapor pressure can be obtained in different ways: by vacuum applied to the permeate ,the most used laboratory procedure, or by cooling the permeate vapor, causing a partial vacuum, and most common industrially.The membrane destillation use heat streans to provide the evaporations. The pervaporation uses differente methods.I hope it help.

Which is correctly expressed?A. toco cartas
B. juego el violín
C. juego fútbol
D. toco béisbol

Answers

The option that is correctly expressed is C. juego futbol.
The verb toco means to touch, so this cannot be correct. And the verb juego is used with sports, so you cannot use it for instruments.

Extra points for answers Compare the ways in which iron-magnesium minerals and feldspars crystallize from magma

Answers

The comparison of the ways in which iron-magnesium minerals and feldspars crystallize from magma is;

Feldspars continually react with magma and change composition but stay as feldspar whereas iron - magnesium react with magma and change into other minerals.

In Bowen's reaction series, feldspar minerals tend to continually change composition, whereas iron - magnesium minerals tend to have an abrupt change of their mineral types.

Now, the feldspars that are formed from cooling of magnma are usually very rich in calcium. Thus, as cooling continues, the feldspars will start reacting with the magma and as such the feldspar composition will undergo some changes. This reaction will lead to zoned crystals that have outer layers very rich in sodium while the core is very rich in calcium.

For the iron - magnesium minerals, when magma starts to cool, a mineral will now start to crystallize but the more the magma cools the more the temperature drops and a whole new mineral will be formed.

Finally, the minerals formed initially reacts with the magma which makes it to be converted into the new mineral.

the magma melts then hardens for a long time then iron magnesium pretty much sugar coats it and crystallizes it.
