Answer:

Explanation:

"The use of smartphones and tablet computers at bedtime can

disrupt sleep, affecting people's health."

Even though smartphones and tablet computers are great technological advances from what technology used to be, they disrupt our sleep, affecting our health. The people who made the advance, probably weren't thinking that they would affect us in a health involved way. They're making even better advancements to our technology today, even right now, hopefully fixing the negative impact it has on us, but also searching for anymore that might become an issue for our health.

.. Which of the following mutations would have the potential to affect future generations of

ch4aika [34]

Answer choices:

A frame shift mutation in the X chromosome of a cheek cell
A chromosomal mutation in the Y chromosome of a kidney cell
A point mutation in the first chromosome of a sperm cell
A substitution mutation in the third chromosome of a uterus cell

Answers:

A point mutation in the first chromosome of a sperm cell

Explanation:

Only mutations that affect the germ line are passed on to the next generation. Therefore, only mutations in the egg and sperm of an individual have the potential to affect the next generation.

Mutations in cheek cells, kidney cells, and uterus cells might cause cell death or cancer. This genetic material is not passed on to the next generation, only the egg and sperm contribute this material. Therefore, only mutations here will affect the generation.

What is spontaneous generation?

kkurt [141]

Answer:

Spontaneous generation, the hypothetical process by which living organisms develop from nonliving matter.

Explanation:

In 1668, Francesco Redi, an Italian scientist, designed a scientific experiment to test the spontaneous creation of maggots by placing fresh meat in each of two different jars. One jar was left open; the other was covered with a cloth. Days later, the open jar contained maggots, whereas the covered jar contained no maggots. He did note that maggots were found on the exterior surface of the cloth that covered the jar. Redi successfully demonstrated that the maggots came from fly eggs and thereby helped to disprove spontaneous generation.

Describe pulmonary circulation pathway using the following terms: deoxygenated blood, left atrium, lungs, oxygenated blood, pulm

ehidna [41]

Definition:
"The type of circulation pathway in which venous blood is passed
from the right atrium of the heart through the right ventricle and
 pulmonary arteries to the lungs where it is oxygenated and its return via the pulmonary veins to enter the left auricle and participate in the systemic circulation".

Explanation:
There are two circulatory path in cardiovascular system namely pulmonary circulation and systemic circulation. Pulmonary circulation path allows for blood circulation through lungs for oxygenation while systemic circulation allows for transport of oxygenated blood to all parts of the body.

Pulmonary Circulation Pathway:
Pulmonary circulation pathway consist of:

1. Superior and inferior vena cava:
De-oxygenated blood from lower parts of the body enter to right atrium through inferior vena cava. Similary, deoxygenated blood from upper parts of the body enter to right atrium through superior vena cava.

2. Right atrium and right ventricle:
From right atrium the blood passes to right ventricle through tricuspid valve.

 3. Pulmonary artery:
Afterwards, the blood enters the pulmonary artery via the pulmonary valve. The pulmonary artery divides into two arteries with one artery entering the right lung and the other artery entering the left lung. When the blood reaches the lungs through the left and right pulmonary arteries, it moves over alveoli via the capillary beds. 

4. Left atrium and left ventricle:
After the blood gets oxygenated, it moves back to the heart and this time moves into the left atrium, completing the pulmonary circulation path.
