Answer:

Crossing over is the exchange of genetic material between non-sister chromatids of homologous chromosomes during meiosis, which results in new allelic combinations in the daughter cells.

When chromosomal homologs communicate with one another during Meiosis I's metaphase, crossing over takes place.

When chromosomes of the same type are paired together during meiosis, a biological event called crossing over takes place.

Parts of the chromosome can be exchanged when two chromosomes, one from the mother and one from the father, line up. The same genes may be present on the two chromosomes in different versions.

The exchange of genetic material between non-sister chromatids of homologous chromosomes occurs during crossing over, an enzyme-mediated process. It happens during meiotic prophase I's pachytene stage.

Crossing over occurs during Meiosis I's metaphase when chromosomal homologs interact with one another.

Thus, this way, crossing over takes place during meiosis.

Cell membrane

Explanation:

Cell membrane is the cellular structure in an animal cell helps maintain homeostasis by controlling the transportation of substances into and out of the cell

Homeostasis is a self regulating process that maintain a stability of internal body with respect to the changing external environment which ultimately maintain a steady state of the living system.

It maintain body homeostasis by regulating body temperature, blood pH, blood glucose level,  sodium, potassium and calcium ion concentrations.

Three mechanisms are involved in homeostasis such as Effector, Receptor, Control Center.

The  homeostasis  can be failed due to two factors such as due to an internal environment or other factors like Genetics, Physical condition, diet, nutrition, toxins, Psychological health etc.

Answer:

The correct answer is temperature.

Explanation:

I took the test.

The density-independent limiting factor is any force that affects the size and population, temperature, hence option b is correct.

In ecology, a density-independent factor is any force that has an impact on the size of a population of living creatures regardless of the population's density.

This term is also known as a limiting factor (the number of individuals per unit area). These density-independent causes include nutritional or food scarcity, environmental contaminants, and harsh weather.

Natural catastrophes, seasonal patterns, odd weather, and human activities are density-independent influences.

Therefore, in addition, catastrophes like fires, temperatures, and storms can have an effect on population increase, hence option b is correct.

Answer:

Based on the given information , the cellular structure , which don not function properly in Tay Sachs disease  is Lysosomes

Explanation:

LYSOSOMES -: In many animal cells, a lysosome is a membrane-bound organelle. These are spherical vesicles containing hydrolytic enzymes that can break down many types of biomolecules.  A lysosome, with both its membrane proteins and its lumenal proteins, has a particular composition. There are a number of enzymes in lysosomes, helping the cell to break down different biomolecules that it swallows, including peptides, nucleic acids, carbohydrates , and lipids (lysosomal lipase). For optimal function, the enzymes responsible for this hydrolysis need an acidic environment.

TAY SACHS DISEASE -:  The autosomal recessive disorder Tay-Sachs is caused by mutations in both gene alleles (HEXA) on chromosome 15. HEXA codes for the enzyme β-hexosaminidase A alpha subunit. This enzyme is contained in organelles, lysosomes, which break down large molecules for the cell to recycle.  

Normally, β-hexosaminidase A helps to degrade a lipid called ganglioside GM2, but the enzyme is absent or present only in very small amounts in Tay-Sachs individuals, enabling excessive accumulation of ganglioside GM2 in neurons. In the different types of Tay-Sachs, the progressive neurodegeneration seen depends on the speed and degree of accumulation of GM2 ganglioside, which in turn depends on the amount of functional β-hexosaminidase A present in the body.

Hence , the answer is lysosomes .

Just like the dinosaurs

Answer:

Then I will probably cry. No I'm kidding, well, not kidding. Whatever. If lynxes went extinct there would probably be a large gap in the food chain, resulting in several other extinction events, and possibly overpopulation. Rabbits would likely thrive, seeing as they are the lynxes main food source, and the rabbits would eat too many plants, causing there to be no plants for the other animals in that environment. Many issues would be caused, and I will probably have a mental episode, because lynxes are my FAVORITE animal. Beautiful, cunning, and an apex predator. By far the most amazing animal on earth.

Answer:

No

Explanation:

Based on the exact methodology that Raul is using he will never produce valid results. This is mainly due to the fact that there are too many changing variables in his experiment. In order to produce valid results, the experiment can only have one changing variable (independent variable) at a time, while all of the other variables need to be controlled/constant. This would allow Raul to isolate which change is actually causing the desired effect in the plants. The way that Raul has his experiment set-up he will not be able to pinpoint exactly what variable or aspect is actually causing the growth of the plants.

Answer:

When an earthquake occurs the seismic waves (P and S waves) spread out in all directions through the Earth's interior. Seismic stations located at increasing distances from the earthquake epicenter will record seismic waves that have traveled through increasing depths in the Earth.

Seismic velocities depend on the material properties such as composition, mineral phase and packing structure, temperature, and pressure of the media through which seismic waves pass. Seismic waves travel more quickly through denser materials and therefore generally travel more quickly with depth. Anomalously hot areas slow down seismic waves. Seismic waves move more slowly through a liquid than a solid. Molten areas within the Earth slow down P waves and stop S waves because their shearing motion cannot be transmitted through a liquid. Partially molten areas may slow down the P waves and attenuate or weaken S waves.

When seismic waves pass between geologic layers with contrasting seismic velocities (when any wave passes through media with distinctly differing velocities) reflections, refraction (bending), and the production of new wave phases (e.g., an S wave produced from a P wave) often result. Sudden jumps in seismic velocities across a boundary are known as seismic discontinuities.

Within the Earth, molten areas slow down P-waves and stop S-waves because shearing motion of the waves cannot be transmitted through a liquid.

Earthquake cause the seismic waves (P and S waves) that spread out in all directions even in the Earth's interior. Seismic waves move more slowly through a liquid than a solid.

Within the Earth, molten areas slow down P-waves and stop S-waves because shearing motion of the waves cannot be transmitted through a liquid.

Therefore, most of the S-waves of an earthquake disappear about a distance of 11,500 km from the epicenter.
