Which of the following is an advantage of internal fertilization
slavikrds [6]

Answer and Explanation:

Internal fertilization is characterized by sperm fertilizing the egg within the female. More protection against outside environments and predators, and therefore a higher chance of surviving until birth .  The young develop within the female, receiving nourishment from the mother’s blood through a placenta. Less chance of desiccation of gametes. Internal fertilization also enhances the fertilization of eggs by a specific male since the females are more selective of their mates thus increasing chances of gametes meeting . Even though fewer offspring are produced through this method, their survival rate is higher.

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.

Which statement about abiotic changes to an ecosystem is true ?
Lena [83]
The very first one is the answer-

Abiotic changes have the ability to dictate biotic ones. This can be caused by humans.
For example: an abiotic thing can be an element like water. If the water in a lake gets poisoned by chemical compounds, this is an abiotic change. However, since the lake is now poisoned it’ll likely harm or even kill fish, bacteria, algae, and any other wildlife living within the lake. It doesn’t stop there though, without the lake surrounding animals won’t have clean water to drink, they can now die from either the poisoning, dehydration, or starvation if they lived off of the aquatic life from the lake.
