A--What do you get if you add the number of maternalchromosomesin a somatic cell to the number of autosomes in a sex
cell, thensubtract the number of Barr bodies in a somatic cell of a
personwith kleinfelter's syndrome?

Answers

Answer 1
Answer:

Answer:

• Men with Klinefelter's syndrome have an extra X chromosome.

• Of the 23 pairs of chromosomes, one pair is called the sex chromosomes because they determine a person's sex. One sex chromosome is inherited from the mother and the other from the father. Mothers always pass on an X chromosome, but fathers can pass on an X or a Y chromosome. -

•The normal male chromosome arrangement is 46XY, but men with Klinefelter's syndrome have 47XXY. The extra X chromosome can come from either parent.

You work in a laboratory that studies the molecular biology of tribbles. [Although tribbles are an alien life form, assume here that the molecular biology of tribbles is identical to that of eukaryotes on Earth.]Your lab has a genomic library of tribble DNA, as well as a cDNA library made with mRNA extracted from whole tribbles. The lab also has a collection of live tribbles that can be used to isolate RNA or DNA, and a supply of fixed tribbles that can be stained for gene expression.Your advisor provides you with a cloned 100 bp DNA fragment that represents part of the protein-coding region of a tribble gene. Using the tools described in the previous paragraph and the molecular biology techniques we have discussed in class, how would you accomplish each of the following aims? Note: try to come up with the simplest and modest direct approach that will give you the desired information.A. Determine the amino acid sequence of the complete protein produced by that gene.B. Determine whether or not the gene contains introns.C. Determine whether the RNA produced by that gene experiences alternative splicing.D. Determine the length of the mature mRNA(s) produced by the gene. This includes the UTRs and the poly-A tail.E. Determine which cells in the tribble body do and do not express mRNA from this gene.F. You discover a blood stain in the lab, and you want to determine whether it is human blood or tribble blood. How can you do this using the molecular biology tools described above?

If you were trying to identify an unknown adult animal that must be either an echinoderm or chordate, which morphological feature(s) would guarantee that your organism was an echinoderm rather than a chordate.

Answers

Answer:

The radial symmetry and mesodermal skeleton in echinodems

Bilateral symmetry and internal skeleton of chordates

Explanation:

The echinoderms have radial symmetry and their skeleton is mesodermal made up of calcites known as ossicles while the chordates have bilateral symmetry and their internal skeleton is made up of bones and cartilages.

Adipose tissues belong to ___________a. nervous tissues
b. muscle tissues
c. connective tissues
d. epithelial tissues

Answers

Answer:

c. connective tissues

Explanation:

Adipose tissue is a connective tissue which is composed of cells called adipocytes. Since it a loose connective tissue located beneath the skin and around internal organs.

The main function of this tissue is to store fat, although it also cushions and insulates the body. It provides protective covering around internal organs. Since it stores fat it also functions as a reserve of nutrients.

Adipose tissue also acts as an endocrine organ. It has the ability to make a number of biologically active compounds that regulate metabolic homeostasis.
