Choose true or false for each statement listed below 1. The total number of autosomal linkage groups in a cell equals the number

of different pairs of homologous autosomes in a cell. 2. The closer two genes are on a chromosome the less likely recombination will occur between them. 3. Two genes that are on the same chromosome can never appear unlinked. 4. Recombinant offspring inherit the same allele combinations as their parents had. 5. Crossing over occurs during meiosis I. 6.When using chi square analysis and possibly linked genes, your null hypothesis must be that the genes are not linked.

<h2>Linkage groups </h2>

Explanation:

1. The number of autosomal linkage groups in a cell is equal to the homologous autosomes in a cell-this statement is true;Number of autosomal linkage group will determine the homologous autosomes

2. The closer two genes are on a chromosome the less likely is the chance that recombination will occur between them-this statement is true;Linkage is directly proportional to distance between two genes

3. Two genes that are on the same chromosome can never appear unlinked-this statement is false;When genes are found on different chromosomes or far apart on the same chromosome, they assort independently and are said to be unlinked.

4. Recombinant offspring inherit the same allele combinations as their parents had-this statement is false;Offspring allele combination might differ because half chromosomes are received from mother and other half from father

5. Crossing over occurs during meiosis I-this statement is true;Crossing over occurs during the Pachytene stage of Prophase I of meiosis I

6.When using chi square analysis and possibly linked genes, your null hypothesis must be that the genes are not linked-this statement is true;Chi-squared tests are a statistical measure that are used to determine whether the difference between an observed and expected frequency distribution is statistically significant

Crinoids, also known as sea lilies, appear to be sea plants but are not plants at all. Crinoids are an echinoderm species which
almond37 [142]

The correct answer is - D) covered by warm shallow seas.

The fact that the crinoids are have an abundance in the fossil records in Pennsylvania in the Mississippian Period, tells us that this area was covered with shallow and warm seas. The reason why we can get that conclusion is that the crinoids live only in that kind of environment, so it simply a logical conclusion.

The geological data is also confirming this, as it is easily noticeable in the layers that during this period of the geologic past, what is now Pennsylvania, was covered with shallow sea waters. Also, this waters were warm too, as the climate was warm and humid and that period, so it was a perfect environment for the crinoids to flourish.

Match the following: A) Smooth muscle B) Skin epidermis C) Tendon D) Cardiac muscle 17) Derived from mesenchyme. ___________ 18)
Stolb23 [73]

1.  

17) Derived from mesenchyme. C) Tendon  

Tendon is fibrous connective tissue (made of collagen) that connects muscle to bone.

18) Has a surface to which nothing is attached B) Skin epidermis.  

Epidermis is one of the three skin layers (other two are dermis and hypodermis) of skin that provides a barrier to infection from environmental pathogens.

9) Moves blood through the body. D) Cardiac muscle  

Cardiac muscle is found in heart which pumps blood through the whole body.

20) Moves food through the GI tract. A) Smooth muscle  

Motility through the GI tract is achieved by the contractions of ring smooth muscles (peristalsis).

2.  

21) Smooth muscle. B) Moderate regenerative ability.  

Cells called pericytes are cells that can regenerate smooth muscle cells. Also, smooth muscle cells themselves retain the ability to divide and thus regenerate (increase their own number).

22) Skeletal muscle C) Weak regenerative ability

Skeletal muscle contain  'satellite cells'-stem cells that have the ability to regenerate and repair the damaged fibres.  

23) Cardiac muscle A) Virtually no functional regenerative ability.  

When the cell of cardiac muscle-cardiac muscle cells die, they are not replaced.

24) Areolar connective tissue. D) Regenerates extremely well

Areolar connective tissue is loose connective tissue that hold organs in place. Fibroblasts are cells widely dispersed in this tissue

25) Tendons and ligaments. B) Moderate regenerative ability  

Healing or regeneration of ligaments and tendons can come from the surrounding soft tissues ("extrinsic healing"), or from the ligament /tendon itself ("intrinsic healing").
