Explanation:

A convergent boundary (also known as a destructive boundary) is an area on Earth where two or more lithospheric plates collide. One plate eventually slides beneath the other, a process known as subduction. The subduction zone can be defined by a plane where many earthquakes occur, called the Wadati–Benioff zone.[1] These collisions happen on scales of millions to tens of millions of years and can lead to volcanism, earthquakes, orogenesis, destruction of lithosphere, and deformation. Convergent boundaries occur between oceanic-oceanic lithosphere, oceanic-continental lithosphere, and continental-continental lithosphere. The geologic features related to convergent boundaries vary depending on crust types.

Plate tectonics is driven by convection cells in the mantle. Convection cells are the result of heat generated by radioactive decay of elements in the mantle escaping to the surface and the return of cool materials from the surface to the mantle.[2] These convection cells bring hot mantle material to the surface along spreading centers creating new crust. As this new crust is pushed away from the spreading center by the formation of newer crust, it cools, thins, and becomes denser. Subduction begins when this dense crust converges with less dense crust. The force of gravity helps drive the subducting slab into the mantle.[3] As the relatively cool subducting slab sinks deeper into the mantle, it is heated, causing hydrous minerals to break down. This releases water into the hotter asthenosphere, which leads to partial melting of asthenosphere and volcanism. Both dehydration and partial melting occurs along the 1,000 °C (1,830 °F) isotherm, generally at depths of 65 to 130 km (40 to 81 mi).[4][5]

Some lithospheric plates consist of both continental and oceanic lithosphere. In some instances, initial convergence with another plate will destroy oceanic lithosphere, leading to convergence of two continental plates. Neither continental plate will subduct. It is likely that the plate may break along the boundary of continental and oceanic crust. Seismic tomography reveals pieces of lithosphere that have broken off during convergence

The motion of the car shows that the first car is moving at a constant speed while.the second car's speed isn't uniform.

The motion of a car can be described in several ways, depending on the level of detail and accuracy required. Here are a few examples:

Speed: The speed of a car is the rate at which it is moving, usually measured in miles per hour or kilometers per hour. It can be described as constant, increasing, or decreasing depending on whether the car is maintaining a steady speed, accelerating, or decelerating.

Direction: The direction of a car's motion can be described as forward, backward, left, right, or any combination of these. For example, a car turning left at an intersection is moving forward but also changing direction.

Distance: The distance a car travels is the length of the path it follows, usually measured in miles or kilometers. It can be described as a function of time, with the distance increasing as the car moves.

Enzo's conclusion regarding the primates is most likely to be that they are less irritable now that they have more habitat to spread out.

The construction of the wire tunnel that runs through the trees and connects to a second habitat on the opposite side of the park gives the primates such as orangutans greater room to roam and explore, which can lessen the likelihood of fights and violent behavior.

Consequently, it is reasonable to infer that the greater space and more habitat offered to them are the causes of the decrease in conflicts between Kwame and Ikon.

A high mass star will not be able to generate enough energy beyond the silicon fusion cycle to stop its collapse because iron fusion doesn't generate excess energy and gas pressure to prevent the core from collapsing. Instead, it requires additional energy.

A high mass star or massive star is a star that is more than 8 times the mass of the sun. For nuclear fusion to continue to occur in such a star, two things are needed, high temperature and pressure. The more temperature and pressure a star has, the more likely it is able to fuse heavier elements like silicon and iron.

Towards the end of the life cycle of a massive star, it starts to fuse silicon, forming iron atoms. These heavy iron particles remain at the core of the star without undergoing any further nuclear fusions. This is because iron has a too much positively charged protons in its nuclei, which causes it to repel the protons in other smaller nuclei like helium, preventing nuclear fusion. Thus, more energy is needed for iron fusion to occur and doesn't give back excess energy or any gas pressure to prevent the core from collapsing, leading to a supernova.

Hence, the reason why nuclear fusion does not work beyond the silicon fusion is that iron fusion requires energy and does not produce any gas pressure.

Answer:

by crossing the sheep with a homo-zygous recessive sheep for “fluff” alleles

Explanation:

In genetics, the term homo-zygous refers to an individual that carries two copies of the same gene variant or 'allele' for a given gene. An individual that is homo-zygous dominant carries two copies of the same dominant allele. A dominant allele is a gene variant that can mask the expression of a recessive allele in heterozygous individuals (i.e., individuals that carry one copy of the dominant allele and one copy of the recessive allele). In a test cross, an individual that is suspected to be heterozygous for a given gene is crossed with a homo-zygous recessive individual in order to examine the phenotypes of the offspring. In this case, if the sheep that is suspected to be heterozygous (i.e., hybrid) is really heterozygous for the fur gene (genotype Ff), then the phenotypic ratio of the testcross progeny (F1) would be 1:1, i.e. 50% of the F1 individuals would have the 'dominant fluffy fur' phenotype (genotype Ff) and 50% of the F1 individuals would have the 'recessive non-fluffy fur' phenotype (genotype ff). Conversely, if the sheep that is suspected to be heterozygous is homo-zygous dominant for the fur gene (genotype FF), then 100% of the F1 individuals would have the 'dominant fluffy fur' phenotype (genotype Ff).

The removal of a keystone species from a community will initiate changes in that community's structure and typically results in a reduction in diversity or collapse of community structure.

This is a kind of cascading effect or a domino effect, where other species are affected due to the absence of the keystone species. This can lead to significant changes in the ecosystem, such as a decline in biodiversity and changes in the food web.

An example of this is the intertidal sea star Pisaster ochraceous.  It is found in the northwestern United States. In a study, the sea stars were experimentally removed from the intertidal zone where they lived. As a result, populations of their prey (mussels) increased, altering the species composition of the community and sharply reducing species diversity. When the sea stars were present, about 25 species of barnacles and algae were found in the lower part of the intertidal zone, but when they were missing, the mussel population expanded downward and almost entirely replaced these other species.

Answer:

W - Facilitates movement of air by expansion and contraction, X - Traps dust and helps to filter inhaled air, Y - Prevents the wind pipe from collapsing, Z - Help in exchange of gases.

Explanation:

Diaphragm is the muscle that separates the thoracic cavity from the abdomen. The diaphragm is the main muscle of respiration. Contraction of the diaphragm muscle expands the lungs during inspiration when breathing air in. The function of the nasal cavity is to warm, moisturize, and filter air entering the body before it reaches the lungs. Hairs and mucus lining the nasal cavity help to trap dust, mold, pollen and other environmental contaminants before they can reach the inner portions of the body. The trachea, or windpipe, is a 5-inch long tube made of C-shaped hyaline cartilage rings lined with pseudostratified ciliated columnar epithelium. The trachea connects the larynx to the bronchi and allows air to pass through the neck and into the thorax. The rings of cartilage making up the trachea allow it to remain open to air at all times. Gas exchange of oxygen and carbon dioxide takes place in the alveoli. Oxygen from the inhaled air diffuses through the walls of the alveoli and adjacent capillaries into the red blood cells. The oxygen is then carried by the blood to the body tissues.

The part of the lungs where Carbon Dioxide concentration is highest is in the part labeled A.

The entire diagram is called ALVEOLI.

This structure is a semi-permeable membrane wired with blood vessels on its walls. It is in these sacs that the body gives off carbon dioxide and takes in oxygen. The blood vessels which are wired around the sacs are called Capillaries.

The part labeled B is the pulmonary artery. It feeds de-oxygenated blood to the capillaries. Through the walls of the capillaries, the carbon dioxide is removed from the blood into the alveoli and takes up oxygen from the air in the alveoli. The oxygenated blood then moves back into the body via the pulmonary vein which is labeled D on the diagram.
