reasons for seasons
Answer:
As the earth spins on its axis, producing night and day, it also moves about the sun in an elliptical (elongated circle) orbit that requires about 365 1/4 days to complete. The earth's spin axis is tilted with respect to its orbital plane. This is what causes the seasons. At different times of the year, the sun's rays hit different parts of the globe more directly. The angle of the Earth's axis tilts the Northern Hemisphere towards the sun during the summer. Without the tilt of the earth's axis, we wouldn't have seasons.

Electrophysiological cell-recording studies have indicated that the _______ may be especially important in the control of internally guided motor sequences, whereas the _______ may be especially important in the control of externally guided motor sequences. A. supplementary motor cortex; premotor cortex B. premotor cortex; supplementary motor cortex C. cerebellum; basal ganglia D. basal ganglia; cerebellum
Answer:
A. supplementary motor cortex; premotor cortex
Explanation:
The supplementary motor cortex, also known as the supplementary motor area (SMA), is an area of the cerebral cortex located anterior to the premotor cortex. This area (SMA) is involved in the execution of complex and rapid sequential movements (e.g., typing). Moreover, the premotor cortex is an area of the motor cortex located between the primary motor cortex and the prefrontal cortex. This area (premotor cortex) is activated during motor tasks including, among others, spatial and sensory guidance of movement.

Explanation:
Select the correct statement about the three-chambered hearts of amphibians and nonbird reptiles. A scheme of blood circulation of reptiles except for birds. The reptiles have a three-chambered heart that consists of two atria and one ventricle with an incomplete septum. There are two circuits: pulmonary and systemic. In the pulmonary circuit, the blood from the right ventricle is pumped in to lung capillaries and returned to the left atria. In the systemic circuit, the blood is pumped from the left ventricle to the systemic capillaries via the left systemic aorta and is then returned to the right atria. There is also one vessel going from the right ventricle to the aorta right before it branches to smaller arteries. This vessel carries mixed blood. All blood on the right side of the circuits is venous and all blood on the left side is arterial. Select the correct statement about the three-chambered hearts of amphibians and nonbird reptiles. The three-chambered hearts of amphibians and nonbird reptiles are facultative, allowing variation in blood flow through the heart. The three-chambered heart is inferior to the four-chambered hearts of birds and mammals, limiting the evolutionary success of amphibians and nonbird reptiles. Pulmonary and systemic blood fully mixes in the ventricle of a three-chambered heart.
Answer:
The three-chambered hearts of amphibians and nonbird reptiles are facultative, allowing variation in blood flow through the heart.
Explanation:
In Anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.
Generally, the cardiac cycle occurs in two (2) stages;
I. Diastole : in this stage, the ventricles is relaxed and would be filled with blood.
II. Systole: at this stage, the muscles contracts and thus, allow blood to be pushed through the atria.
All amphibians and reptiles except for crocodiles (having four-chambered heart) have three-chambered hearts, which typically comprises of a partially divided ventricle and two atria.
Hence, the correct statement about the three-chambered hearts of amphibians and nonbird reptiles is that, the three-chambered hearts of amphibians and nonbird reptiles are facultative, allowing variation in blood flow through the heart due to the partially divided ventricle.

True or false--
All the modern species of bison have evolved overtime just as all living organisms evolve over time.
Answer:
The working assumption for many years was that, like North American bison, European bison evolved from steppe bison. ... Their results suggest that the European bison is the result of inter-breeding, over 120,000 years ago, between steppe bison and aurochs; the wild ancestors of modern domestic cattle.
Our study suggests that the first bison arrived in North America 195 - 135 thousand years ago over a land bridge between Asia and Alaska. They quickly spread and evolved (changed) into different forms to adapt to their new environments.

Algae possess chlorophyll in their cells. They use carbon dioxide in a manner that is analogous to how we use food. Thus, option B is correct.
What is a characteristic feature of algae?By converting light energy to chemical energy through the process of photosynthesis, carbon dioxide and water are transformed into organic molecules.
Nearly all algae engage in the process, and in fact, much of what is currently known about photosynthesis was first uncovered through research on the green alga Chlorella.
Like other plants, algae benefit from sunlight, therefore denying them of it will limit or even completely stop their growth. For several days, completely shading the tank or aquarium from light is essential.
Therefore, algae require sunshine because algae can photosynthesize, or use sunlight to change carbon dioxide into biological material.

Answer: 7. Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. ... While photosynthesis requires carbon dioxide and releases oxygen, cellular respiration requires oxygen and releases carbon dioxide. 8.

The number of chemical industries along Florida's rivers is increasing. What is the most
likely consequence of this increased industrialization?
O a decrease in the amount of water pollution
O an increase in the amount of water available for recreational use
an increase in the destruction of natural food webs
O a decrease int he amount of water needed by industry
Answer:
The correct answer would be - an increase in the destruction of natural food webs.
Explanation:
Increasing chemical industries near the river cause harmful effects to the environment by various means, including air pollution, dumping untreated chemical or industrial waste, and wastewater in the river. This will lead to a lack of potable water, contamination of the food chain, destruction of biodiversity, and many more.
The destruction of biodiversity can be caused by the increasing the unbridled growth of phytoplankton, eutrophication process that will consume more oxygen and cause algal bloom and decrease the oxygen in the water and destroys the organism and natural food web.
The real length of one villus is 0.8 mm
Calculate the image length if the villus is viewed at a magnification of x20
magnification = size of image / size of real object
