The leakiest capillaries, which allow large substances such as cells to cross the capillary walls are called sinusoidal capillaries.
Sinusoidal capillaries are a unique kind of capillaries that are wide in diameter. The diameter of a sinusoidal capillary is 30 to 40 nm.
Sinusoidal capillaries can be found in the liver, spleen, and bone marrow. In the spleen, sinusoidal capillaries help in the filtration of blood. They remove broken red blood cells, antigens and other pathogens remains in the blood.
Sinusoidal capillaries are known as leakiest capillaries because all other capillaries have a narrow diameter and do not allow the passing of large substances. Sinusoidal capillaries are the only ones with a large diameter that allows the passing of larger substances.

Answer: its called an operon
Explanation:
In genetics, an operon is a functioning unit of DNA containing a cluster of genes under the control of a single promoter. ... Operons are also found in viruses such as bacteriophages.
Answer:
Helium
Explanation:
We know that this atom has two positive particles on the nucleus (protons) with two neutral particles (neutrons). We can also see that it hass two electrons on the orbitals. Knowing this, we can say that the element is Helium.
Helium has a relative atomic mass of 4 and it's atomic number is 2. The atomic number is equal to the number of protons and electrons the atom has, and the atomic mass can be used to calculate the number of neutrons:
Relative atomic mass = Neutrons + atomic number
So we know that:
Neutrons = relative atomic mass - atomic number
Neutrons = 4 - 2 = 2.
Answer:
Science inquiry means to learn or find out about something new, and using evidence from the investigations to create logical explanations, so the answer is most likely false
<span>The answer to this question is the second option-" carbohydrate polymers formed as water is removed". In the dehydration synthesis, polymers are created. This is when two molecules formed a new product which results the loss of water. So, this is a process of forming or making a new compound together with the removal of water.</span>
