Answer:
2c. Jamestown Settlement and the "Starving Time"
Explanation:
The first joint-stock company to launch a lasting venture to the New World was the VIRGINIA COMPANY OF LONDON. The investors had one goal in mind: gold. They hoped to repeat the success of Spaniards who found gold in South America.
In 1607, 144 English men and boys established the JAMESTOWN colony, named after King James I.
The colonists were told that if they did not generate any wealth, financial support for their efforts would end. Many of the men spent their days vainly searching for gold.
As a consequence, the colonists spent little time farming. Food supplies dwindled. MALARIA and the harsh winter besieged the colonists, as well. After the first year, only 38 of the original 144 had survived.
PLZ MARK BRAINLIEST
<span>The
peripheral nervous system (PNS) are all neurons located outside the brain and
spinal cord (which is the central nervous system [CNS]). There are two types of
peripheral nervous system: sensory (afferent) neurons and motor (efferent)
neurons. The former carries bits of information from the sense organs (touch,
smell, taste, hearing, and sight) around the body to the brain and spinal cord,
while the latter transports messages from the central nervous system (brain and
spinal cord to the muscles and glands.</span>
During inhalation, you breathe in and this contracts the diaphragm and moves downwards. This increments the chest cavity space which means the lungs are expanding. The intercostal muscles or the muscles in between the ribs also aids in the enlargement of the chest cavity. Both muscles contract to pull your rib cage upward and outward when you inhale. As your lungs expand, air is sucked through your nose and mouth. It then travels down to the windpipe and into the lungs to the bronchus, bronchioles and eventually in the alveoli where air exchange between carbon dioxide and oxygen happens.
The additional accessory muscles of respiration are typically used only under conditions that are of high metabolic demand or respiratory dysfunction. However, in instances where these muscles become stiff and hard, expansion of the rib cage can be quite restricted. The accessory muscles of respiration include sternocleidomastoid and the scalene muscles namely anterior, middle and posterior scalene. Both aid in elevating the rib cage. However, their involvement seems to depend on the degree of respiratory effort. During quiet breathing, the scalenes are consistently active at certain phases while the sternocleidomastoid is quite.
Answer:
Option B.
The level of carbon in the atmosphere will decrease if humans do nothing to cycle.
Explanation:
- The carbon cycle which is also known as the bio Geo chemical cycle is the process that involves the exchange of carbon between the layers: biosphere, geosphere, hydrosphere, and atmosphere of the Earth.
- In this cycle process, the carbon dioxide is eliminated from the atmosphere primarily by the process called as the photosynthesis process (which occurs in green plants) and get into the terrestrial and oceanic biospheres by dissolving into rainwater.
