Explanation:
Cardiac output is the amount of blood pumped by the heart in one minute. Which of these will increase cardiac output?
Answer: the factors that increase cardiac output include:
--> Nervous stimulation and
--> Hypertrophy of the heart.
Explanation:
Cardiac output can be defined as the quantity of blood pumped into the aorta each minute by the heart. This is also the quantity of blood that flows through the circulation. There are factors that can cause increased cardiac output or that can lead to a hypereffective heart. They are:
--> NERVOUS STIMULATION: The combination of sympathetic stimulation and parasympathetic inhibition does two things to increase the pumping effectiveness or cardiac output of the heart. These include:
• it greatly increase the heart rate from the normal level of 72 beats/mum up to 180 to 200 beats /mom.
• it increases the strength of heart contraction, which is called increased contractility to twice it's normal strength.
--> HYPERTROPHY OF THE HEART: A long term increased workload, but not so much excess load that it damages the heart, causes the heart muscle to increase in mass and contractile strength in the same way that heavy exercise causes skeletal muscles to hypertrophy. This effect of increased muscle mass of the heart, allows the heart to pump much greater than usual amounts of cardiac output.
Where do consumers directly get matter and energy to live and grow?
Explanation:
Consumers must consume, or eat, other organisms to get matter and energy to live and grow. Consumers have to eat other consumers or plants to get food. Humans are consumers. We consume many kinds of plants and other organisms.
Match the following terms with the correct definition. Arterioles Arteries Capillaries Venules Veins Small vessels that carry blood away from the heart to the capillaries are __________. Muscular-walled vessels that carry blood away from the heart are _______. One-cell-thick microscopic vessels that function to exchange nutrients and wastes are _________. Small vessels that connect to the capillaries that carry blood back to the heart are ________. Vessels that carry blood back to the heart are _________.
Answer:
Small vessels that carry blood away from the heart to the capillaries are Arterioles. Muscular-walled vessels that carry blood away from the heart are Arteries. One-cell-thick microscopic vessels that function to exchange nutrients and wastes are Capillaries. Small vessels that connect to the capillaries that carry blood back to the heart are Venules. Vessels that carry blood back to the heart are Veins.
Explanation:
We have different types of vessels in our bodies. We can divide them by their size and structure. Starting from the ones that carry blood away from the heath, we have the arteries. Arteries are vessels of big diameter that have muscle around them. Then, the arteries branch into arterioles, which have a smaller diameter. The arterioles branch into capillaries. These are small vessels with thin walls that allow the exchange of nutrients, wastes, and gases with the neighboring tissues. Once that the blood flows through the capillaries, it goes to the venules, which are small veins that will carry the blood to the veins and these to the heart. The veins do not have muscles in their structures, and their walls are thinner than the ones in the arteries.

Forensic scientists have been called by police to come to a home. There is a dead body in the living room, which has been found by the victim's dog walker when she entered the home through the back door. The front door was shut and locked, and there is no sign of other forced entry. The dog walker states that a vase is missing from the living room. What would be the best question for the forensic scientists to ask in this situation?
Where is the missing vase?
How did the victim die?
How did the robber get in the house?
Did the dog walker steal the vase?
Answer:
I think it might be how did the victim die because they might have died of a heart attack or something normal. Then they can start asking where the vase went.

please help asap (photosynthesis)
Answer:
ATP and NADPH
Explanation:
Photosynthesis starts out using the energy from sunlight to get things started, but it ends with the dark reactions, which don't need sunshine to complete sugar production. In the Calvin cycle, ATP and NADPH from the light reactions are used to produce sugars.
So, the correct option is, 'ATP and NADPH'.

Many different types of mutations can occur within the body. Cystic fibrosis is a genetic disorder that is caused by different mutations within the CFTR gene. One mutation in the CFTR gene that leads to cystic fibrosis causes translation to end earlier in the gene sequence. Which type of mutation causes this translation error that leads to cystic fibrosis?
Answer:
The type of mutation that causes this translation error is called deletion. Deletion occurs when a section of a DNA is deleted or lost. In cystic fibrosis, three nucleotides are deleted that results in the lost of phenylalanine
The Tibetans and Han Chinese share several genetic traits and DNA. However, the EPAS1 gene, which increases the ability of red blood cells to carry oxygen even in low oxygen environments, is only commonly found in the Tibetan population that live in higher elevations. Explain why this gene is only common in Tibetan populations from the perspective of competitive advantage and natural selection. Write your answer in three to five sentences.(4 points)
Answer:
When in higher altitudes, ticker blond has a tendency to cause problems like heart attack's, however the Tibetans have adapted to the high altitudes and this has made their blood thinner in order to keep them safe in the altitudes, including that it has low oxygen rates in the altitude therefore providing more oxygen in the bloods cells.
Explanation:
:D It's not my best explanation but I hope this helps <3.
Owing to the fact that ability of the redblood cells to to carry oxygen even in low oxygen environments is neccessary at high elevations, the Tibetan population that live in higher elevations are found to possess the EPAS1 gene.
What is natural selection?The term natural selection refers to the fact that organisms that are better adapted to their habitat will live longer and reproduce. Now we have to note that owing to the elevation at which they live, the people that possess this EPAS1 gene can cope with oxygen stress that could likely occur at a high altitude.
As such, the Tibetan population that live in higher elevations are found to possess the EPAS1 gene.

Name 4 morphological and 2 behavioral traits that can distinguish between a seal and a sea lion.
Answer:
#HEY MATE HERE IS YOUR ANSWER#
Explanation:
Both seals and sea lions, together with the walrus, are pinnipeds, which means "fin footed" in Latin.
But seals' furry, generally stubby front feet — thinly webbed flippers, actually, with a claw on each small toe — seem petite in comparison to the mostly skin-covered, elongated fore flippers that sea lions possess.
Secondly, sea lions have small flaps for outer ears. The "earless" or "true" seals lack external ears altogether. You have to get very close to see the tiny holes on the sides of a seal’s sleek head.
Third, sea lions are noisy. Seals are quieter, vocalizing via soft grunts.
Fourth, while both species spend time both in and out of the water, seals are better adapted to live in the water than on land. Though their bodies can appear chubby, seals are generally smaller and more aquadynamic than sea lions. At the same time, their hind flippers angle backward and don't rotate. This makes them fast in the water but basic belly crawlers on terra firma.
Sea lions, on the other hand, are able to "walk" on land by rotating their hind flippers forward and underneath their big bodies. This is why they are more likely to be employed in aquaria and marine shows.
Finally, seals are less social than their sea-lion cousins. They spend more time in the water than sea lions do and often lead solitary lives in the wild, coming ashore together only once a year to meet and mate.
Sea lions congregate in gregarious groups called herds or rafts that can reach upwards of 1,500 individuals. It's common for scores of them to haul out together and loll about in the sand, comprising an amorphous pile in the noonday sun.
