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.

Explanation:
why does a male body produce more testosterone than a female's body
Answer:
Levels depend on a person's age, sex, and health. Males usually have much higher levels of testosterone in their body than females
Explanation:
As the metabolism of testosterone in males is more pronounced, the daily production is about 20 times greater in men. Females are also more sensitive to the hormone

what is the potential disadvantage of external digestion
Whoever gets it right i will mark brainest
Answer:
For Desssert: C
For Taiga: A
For Tropical Rainforest: B
Explanation: Because desserts are very hot, we know that there aren't much plants due to the lack of rain/water, they're dry. Rainforests have lots of plants, so it's not B, and since the dessert is high temperature, A is obviously off the list.
Taiga is cold so it won't be good for soil and the plants won't grow as good as the wet rainforest so we can pick A. Then B for #2

Each kidney contains ____ of nephrons. Each is _____ but extremely _____, much like a neuron(but shorter).
Answer:
One million.
Explanation:
Each kidney contains about one million of nephrons. The nephron is the structural and functional unit of the kidney means that our kidney is made up of nephrons. The main function of nephron is to produces urine in the process of removing waste, toxic and excess substances from the blood. kidney is responsible for the filtration of blood by removing all the waste materials and taken these waste materials to the excretory organs in order to remove from the body.

The most likely reason(s) a metastatic tumor cell might lose its connection to the basal lamina would be: a change in the integrin proteins from the cell's surface. a change in the cadherin proteins on the cell surface. a change in connexins disrupting gap junctions. All of these choices are correct.
Answer:
A change in the integrin proteins from the cell's surface.
Explanation:
Integrin proteins' principal function is to attach the cell to the basal lamina. Also, they transmit signals from the extracellular matrix to the interior of the cell. A change in the integrin could result in loss of connection between the mutated cell and the basal lamina.
Cadherin proteins connect one cell to another. A change in these proteins will not result in the loss of connection between the metastatic tumor cell and its extracellular matrix. It most likely will affect the communication and adhesion of cells.
A change in connexins will disrupt the communication between cells but not the connection to the lamina basal. Connexins are transmembrane proteins that connect one cell to another with gap junctions that allow the passage of different components from cell to cell.

Where can proteins be found when part of a plasma membrane?
Answer:
Peripheral membrane proteins are found on the outside and inside surfaces of membranes, attached either to integral proteins or to phospholipids. Unlike integral membrane proteins, peripheral membrane proteins do not stick into the hydrophobic core of the membrane, and they tend to be more loosely attached.

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.

Brain lateralization refers to the ability of the brain to process multisensory information ability of the brain to process multisensory information A capacity of the brain to control basic motor movements capacity of the brain to control basic motor movements B aptitude of the brain to produce speech aptitude of the brain to produce speech C ability of the brain to control basic functions such as respiration and blood circulation ability of the brain to control basic functions such as respiration and blood circulation D inclination for certain cognitive processes to be specialized to one hemis
Answer:
The correct answer is D ''inclination for certain cognitive processes to be specialized to one hemisphere of the brain or the other.'
Explanation:
Lateralization refers to the different specialization of the cerebral hemispheres, that is, it is the functional specialization of the nervous system that is observed to a different degree on one side or the other of the neuroaxis. Our brain is subdivided into two hemispheres, the right and the left. The left hemisphere is more specialized in language and control of emotions and the right in spatial thinking, perception of emotions and facial recognition.

Answer:
The new regulation will help reduce the amount of green house gases available in the atmosphere thereby saving our environment from the Green house effect
Explanation:
Chlorofluorocarbons are examples of greenhouse gases which contribute to the Green house effect been experienced in our environment, by destroying the earths' Ozone layer
If the Government sets a new regulation that prohibit its use in sprays and refrigerants it will help reduce the amount of green house gases available in the atmosphere thereby saving our environment from the Green house effect
Answer:
that act will help the sustainability of out environment because : C. It will slow down the degradation of the ozone layer
The usage of CFC will crate chlorine atoms that catalyze ozone degradation. By prohibiting this product, Government will slow down Ozone's degradation
