Answer: Components of cell junctions

Explanation:

<u>Fibroblasts are cells located in the dermis,</u> responsible for the formation and remodeling of tissue. They synthesize fibers and maintains the extracellular matrix of the tissue of animals. So, t<u>he extracellular matrix is a structurally complex entity that surrounds and supports the cells found in tissues</u>.

A cell junction a structure that exists within the tissues of animals and they consist of protein complexes that provide contact between cells or between a cell and the extracellular matrix. So if the cells do not appear flattened and do not attach to the extracellular matrix, then there is a problem with the components of cell junctions, which are mostly proteins as it was said before. And since proteins are coded by genetic information stored in DNA, then if there is a mutation in any of those genes, the fibroblast will fail to attach because the protein of the cell junction will be abnormal.

<h3>Answer: </h3><h3 />

25%

<h3>Explanation:</h3>

Following a cross between <u>Ttbb</u> and <u>ttBb</u>, the resulting offspring would be:

TtbB , TtbB , Ttbb , Ttbb , ttbB , ttbB , ttbb , ttbb , TtbB , TtbB , Ttbb , Ttbb , ttbB , ttbB , ttbb , ttbb

To have a clearer idea, see the attached image.

Of the 16 possible combinations from this dihybrid cross, there will be:

4 tall plants with blue flowers

4 tall plants with white flowers

4 short plants with blue flowers

4 short plants with white flowers

There are 4 possible genotypic recombinations that would yield short plants with white flowers out of a possible 16, so the chance that the offspring will be short with white flowers would be 4/16 which is 1/4 or 25%

The grades of a science test are normally distributed. Thanh finds that his grade on the test has a z-score of –2.5. Which of th

Tom [10]

The right answer is Thanh's grade is 2.5 standard deviations below the mean of the test grades.

The z scores are standard deviations. If, for example, a tool returns a z score of +2.5, it means that the result is a standard deviation of 2.5.

Very high or very low (negative) z scores associated with very low p values are at the ends of the normal distribution.
