Answer:
The hydrophilic nature of the stain explains that these molecules are polar and charge molecules. therefore, attracts the water molecule but due to their polar nature, it will avoid lipid or fat molecules.
Adipocytes are the cells that are made up of fat or lipids that are hydrophobic due to their non-polar nature and due to this fact, these hydrophilic stains will not be able to stain adipocytes and will not be colored by the stain.
5 Clear Mark for Review Sacculina carcini is a barnacle that attaches to the underside of the green crab. The barnacle finds a hole in the green crab's exoskeleton, then uses microscopic hairs to feed on nutrients from the green crab's blood. The barnacle also lays its eggs in the green crab reproductive system, which sterilizes the green crab. Which term describes the role of S. carcini in this relationship?
Answer:
S. carcini is a parasitic barnacle species
Explanation:
Parasitism: In this case, one of the species is beneficiated, while the other suffers a consequence, reducing its fitness. These interactions are mostly about nutrition, although there might be other benefits too. Some parasite species might coexist with their host, while some others might get them ill to the point of causing death. Parasitic attacks might be very nocive, and even though they are not lethal in a short period of time, they might slowly kill the host.
Parasitic species consume part of the host, but not the whole body. They develop an intimate relationship with their host.
The Host increases the fitness of the parasite speciesThe parasitic species decreases the fitness of the host.By taking the nutrients from the green crab's blood and sterilizing it, the barnacle causes a decrease in the fitness of the crab. The crab becomes weaker and its survival chances decrease, and they have no opportunity to reproduce. Meanwhile, the barnacle gets stronger and reproduces normally.
Use your knowledge of amino acids for energy metabolism to select the term that best completes each description. Glucose cannot be made when amino acids are converted to_________ . In the TCA cycle, some amino acids enter directly and, therefore, can continue in the cycle to generate energy and_______ . When is available, the body can use and glycerol to make some non-essential amino acids.
Answer:
Acetyl CoA; glucose
Explanation:
Acetyl-CoA is a molecule known to be part of different reactions during carbohydrate, protein, and lipid metabolism. Pyruvate (also known as pyruvic acid) is a molecule whose decarboxylation produces acetyl-CoA. Glucose cannot be synthesized when amino acids are converted to Acetyl CoA because this molecule (Acetyl CoA) cannot be converted back to pyruvate. The citric acid cycle (CAC), also known as the tricarboxylic acid (TCA) cycle, is a group of biochemical reactions that release energy by oxidation of acetyl-CoA obtained from sources such as proteins, carbohydrates and fats. During amino acid metabolism, glucogenic amino acids and TCA intermediates can be converted into glucose through gluconeogenesis.
What might happen if the
order of expression of the
highlighted Hox gene was
disrupted, moved, or changed by mutation?
If the order of expression of the highlighted Hox gene was disrupted, moved, or changed by mutation, it would cause the replacement of a part of the body by a structure whose normal location would correspond to another site.
The differentiation of the limbs occurs during embryogenesis, thanks to the action of a group of specialized genes, called Hox gene.
This gene is involved in the developmental program that determines the location of organs along the anteroposterior axis.
These subdivide the embryo along the head-tail axis into cell fields with different developmental potentials, which will transform into limbs and other structures.
Hox gene mutations thus show that there are genes that can control the different regions of the genome that determine the structures of an organism.
These produce considerable anatomical transformations that, in the case of the fly, can consist of:
The formation of wings instead of halteres or legs.An extra pair of wings where small appendages called stabilizers would normally be.Therefore, we can conclude that if the order of expression of the Hox gene was disrupted, moved, or changed by mutation, it would cause the structures normally found in one body segment of the fly to be replaced by found in another segment.

A: 0%
B: 25%
C: 50%
D: 100%
Answer:
The correct answer is - option A. 0%
Explanation:
The zygote formation or fertilization in flowering plants occurs by the fusion of pollen of one plant with the ovum of another plant of the same species normally. This process includes the exchange of an equal amount of the genetic contribution from both plants.
The egg cell of the mother is responsible for the mitochondria and chloroplast of the progeny so the percentage of chloroplast genes provided via Plant R is 0% as ovum and egg cell comes from only plant Q.

What might happen to the magma convection currents if there were no radiogenic heat produced in the core?
How would this affect life on Earth?
Plz help me
Answer:
If there were no radiogenic heat produced in the core, there would be no convection currents, and life on the Earth would not be possible.
Explanation:
The convection currents are the result of heating by temperature gradients. Differences in temperature and density produce these currents. Warm materials are lighter and can ascend, while cold materials are heavier and denser, so they tend to descend. These materials movements create a circular motion pattern known as convective currents. They occur in the atmosphere, in the water, and the Earth mantle. In the last case, while the hot material emerges from the bottom areas, the cold mantle sinks, creating a circular convection current. These play a significant role in fluids circulation and might be responsible for the movements of the lithospheric plates that are over the mantle. The temperature on the surface is much inferior that the mantle´s temperature, so the lithospheric pieces sink, creating a descendent current. Near the terrestrial core, the heat might reach up to 3,500ºC, and solid materials in these areas melt and fuse. When fusing, materials lose density, becoming lighter and ascending again to the surface, creating the ascending currents. The currents of ascending materials are known as thermal feathers or plumes.
Hot ascending material keeps the surface warm, making life possible. Also, radiogenic heat produced in the core is responsible for the electromagnetic field.
The electromagnetic field protects the Earth from many particles that come forward to the surface from space, specifically from the sun. The electromagnetic field also influences the atmosphere, keeping it in its place, necessary for life on Earth.
The plate´s movement produces earthquakes and volcanic activity. Both of them also necessary for many reasons, such as keeping fertile soils and producing necessary atmospheric gasses.
Through the years, the core losses heat, and eventually, it will become solid. When this happens, convective currents will stop because there will be no heat from the bottom to make them move. The electromagnetic field will disappear, and the atmosphere will be affected as well. The Earth surface will become cold. Mantle movement will stop, and there will be no earthquakes nor volcanic activities. Every living being on Earth will be affected by this fact. Life on Earth will not be possible.

When is genetic drift a major factor in evolution?
O A. When there is low gene flow
O B. When there is high selective pressure
O C. When there is sexual selection
O D. When there is female choice
Answer:look at pic
Explanation:
When there is high selective pressure is the major factor in evolution.
What is Genetic drift?Genetic drift is the arbitrary change in the population's frequency of a gene variant that already exists. Gene variations may totally vanish due to genetic drift, which would limit genetic diversity. Moreover, it can make previously uncommon alleles far more common and even fixed.
Genetic drift is an evolutionary process in which the frequency of a given gene allele varies randomly across a population.
The impacts of genetic drift can be severe, often causing traits to become excessively common or to vanish from a community, even though it predominantly affects small, isolated populations.
Therefore, When there is high selective pressure is the major factor in evolution.

1. Why is California at hingher for earthquakes than North Dakota
Answer:
because California is located on the San Andreas Fault
Explanation:
California is one of the states that have higher seismic activity because it lies on an individual fault known as the San Andreas Fault. Faults are regions where two tectonic plates are moving with respect to one another, thereby they are prone to suffer earthquakes. The San Andreas Fault is a continental fault that extends approximately 800 miles (1,200 kilometers) through the US state. Conversely, earthquakes in North Dakota are uncommon because this state is located in the middle of a tectonic plate. The last earthquake in North Dakota had a magnitude of 3.3 (Richter Scale) and it happened almost 10 years ago (2012), in Williston.
