What would be the physical sign that a bone cannot continue longitudinal growth?
faltersainse [42]

Answer:

c) The presence of an ephiphyseal line

Explanation:

The options should be:

a) the presence of osteoblasts

b) the presence of osteons

c) The presence of an ephiphyseal line

d) the presence of hyaline cartilage on the ends of the bone

Explanation:

In vertebrates, the epiphyseal line is formed once the bone is completely grown. This occurs inside a plate known as the epiphyseal plate.

From the age of 18 to 21, the bone stops growing and the cartilage inside this plate gets replaced by bone. However, bones can keep growing in width until we are approximately 25 years old.

Therefore, the physical sign that indicates that a bone cannot continue longitudinal growth would be the presence of an ephiphyseal line.

Protein disulfide isomerase (PDI) is a protein folding enzyme that catalyzes disulfide–sulfhydryl exchange reactions. Ribonuclea
lakkis [162]

Answer:

The effect of protein disulfide isomerase on insulin signifies that the active conformation of insulin is not the most thermodynamically favored form. The main reason behind this is that the protein disulfide isomerase seems to decline the free energy, that is, it makes them more steady form predominant.  

In the case of insulin, the prevalence of the stable form results in its inactivation. Thus, it signifies that the active form is not thermodynamically stable.

As the sample size increases, the t-distribution becomes more similar to the ________ distribution. a. normal b. binomial c. chi
kvv77 [185]

As the sample size increases, the t-distribution becomes more similar to the <u>normal</u> distribution.

<u>Option:</u> A

<u>Explanation:</u>

Student t-distribution is any member of a group or family of constant probability distributions that emerge in circumstances where the sample size is limited and the standard deviation of the population is unspecified when calculating the mean of a naturally distributed population.

The z-distribution implies you are conscious of the normal population deviation (never in case) when used for sample means. The t-distribution is focused on using the standard sample deviation as an approximation of the standard deviation in population.

Describe the chemical make up and type of bonding found in water molecules?
andre [41]
Water molecules consist of 2 Hydrogen and 1 Oxygen atom. They are bonded by a polar covalent bond, meaning the electrons shared by the covalanet bonds are not evenly distributed. Oxygen is more electronegative than Hydrogen and will pull the electrons from its bonds with Hydrogen closer to itself. Thus results in a partial positive dipole on the Hydrogen of the water molecule and a partial negative dipole on the Oxygen of the water molecule. These partial charges allow water to hydrogen bond with one another through a process called cohesion.
