The correct option is this: POTENTIALLY LESS PAINFUL ALTERNATIVES TO RETROORBITAL BLOOD COLLECTION INCLUDE LATERAL SAPHENOUS AND JUGULAR VEIN BLOOD COLLECTION.
Rats are very important in research work and they are often used to test the effects of various substances in the body. To do this, blood has to be collected from the rats and this can be done in various ways. But some methods of blood collection is more painful than the others.

IgorLugansk [536]
They are solitary animals, especially males who do not live in groups, unlike the female which can form small groups of three or four members with their young.

The males are very territorial, so take care of their personal space and the females with whom they mate. To mark their territory, they spray the trees and rocks with a mixture of urine and musk.

Both male and female, they are related only in times of mating and reproduction. There have been cases where the male is responsible for feeding breeding if the mother has died.

The gestation period lasts between 98 and 108 days and give birth to two to four cubs weighing just over a kilo. They have a short life expectancy, as only get to live 10 to 12 years in the wild, but in captivity Natural mortality manage to live up to 26. It is mainly due to the fighting between males

how do engineers use models and earthquakes simulations to test designs for earthquake resistant buildings and structure
Oksana_A [137]

In Earthquake testing, the engineers are using the world largest shake tables to test new construction methods for buildings in the areas prone to the earthquake.

<u>Explanation:</u>

They believed that they have the devised a system to build the taller wood-frame buildings that can still safely withstand even very powerful tremors. To withstand the collapse, the buildings need to redistribute the forces that travel through them during a seismic event.

Shear wells, cross braces, diaphragm, and moment-resisting frame are the central reinforcing the building. Shear wells are the technology of the useful building. That helpful to transfer the earthquake forces.

Readme [11.4K]

Answer:

option 1

Explanation:

In assemblying the nucleosome, this reaction occurs in two main steps. the H3 and H4 are recruited first to the DNA in pairs forming the H3/H4 tetramer; meaning two of H3 and two of H4. This gives rise to the nucleosome precursor. Then after this, the dimers of both H2A/H2B are recruited to this precursor, to give rise to the octamer structure around which the DNA is wrapped.
