Whales are closely related to hoofed mammals with an even number of toes, such as horse, because they evolved from them. Before whales were what we know them as today, they were relatively similar to horses. They used the water to flee from predators, and they evolved slowly to heighten their swimming ability, eventually becoming modern day whales. Fish have always been aquatic animals that have gills. Whales cannot breathe underwater, so they take in oxygen the same way a horse does. Also, both horses and whales are mammals that give birth to their offspring and are warm-blooded. Fish lay eggs and are cold-blooded.

Hope this helped! Please give brainliest! :)

Define the following terms in regards to the brain: ventricles, hemispheres, gyri, sulci, fissures, lobes, cerebral cortex.
Ymorist [56]

Answer:

ventricules.-The ventricles of the brain are a communicating network of cavities filled with cerebrospinal fluid (CSF) and located within the brain parenchyma. The ventricular system is composed of 2 lateral ventricles, the third ventricle, the cerebral aqueduct, and the fourth ventricle.

Hemispheres.-The left side of the brain is responsible for controlling the right side of the body. It also performs tasks that have to do with logic, such as in science and mathematics. On the other hand, the right hemisphere coordinates the left side of the body, and performs tasks that have do with creativity and the arts.

Gyri and Sulci.- Sulci, the grooves, and gyri, the folds or ridges, make up the folded surface of the cerebral cortex.  A sulcus is a shallower groove that surrounds a gyrus.

Fissures.- A fissure is a large furrow that divides the brain into lobes and also into the two hemispheres as the longitudinal fissure.

Lobes.- Each side of your brain contains four lobes. The frontal lobe is important for cognitive functions and control of voluntary movement or activity. The parietal lobe processes information about temperature, taste, touch and movement, while the occipital lobe is primarily responsible for vision.

Cerebral cortex.- the furrowed outer layer of gray matter in the cerebrum of the brain, associated with the higher brain functions, as voluntary movement, coordination of sensory information, learning and memory, and the expression of individuality.

How would your body respond if your blood pH raised to 7.46?
trapecia [35]
Well an increase in alkaline causes pH levels to rise. When the levels of acid in your blood are too high, it's called acidosis. When your blood is too alkaline, it is called alkalosis. Respiratory acidosis and alkalosis are due to a problem with the lungs.

Explain how convection currents drive the movement of tectonic plates in the lithosphere by describing the two plate interaction
Goryan [66]

Answer:

The semi-plastic rock of the mantle behaves like water being heated. The lower mantle is hotter than upper mantle because it is closer to the hotter core of the earth. Therefore, this part of the mantle is less dense and tends to rise as the upper cooler denser mantle close to the crust sink to the bottom. These convection currents are similar to those of water in a container being heated from below.

The circular motion of these currents tends to drag along the crust due to force of friction between the lower crust and upper mantle. This is what powers tectonic plate movements. When two plates are driven by currents that intersect and churn in the same direction, they collide, at a convergent boundary as shown in position D in the illustration. The denser plate is subducted beneath the other. At position E, two plates are moving away from each other (called a divergent boundary) because each plate is being driven by a different convention current in the mantle. These current are cycling in opposing directions (one clockwise the other anti-clockwise).
