Answer:

A reflex arc with single synapse (integrating center) is a monosynaptic reflex arc.

Explanation:

A reflex arc consists of sensory neurons, motor neurons, integrating center, sensory receptors, and effectors.

A monosynaptic reflex arc is the one that consists of only a single synapse in the central nervous system. This means that the whole monosynaptic reflex arc has only one synapse between single sensory and motor neurons.

In horses, black color(B) dominates chestnut color(b). The trotting gait(T) dominates the pacing gait (t). A cross is made betwe

bulgar [2K]

Answer:

<h2>a. BbTt;</h2><h2>b. BbTt X BbTt ;</h2><h2> Parent 1: BT bt Bt bT </h2><h2> Parent 2: BT bt Bt bT ;</h2><h2>c. BBTT , BbTt , BBTt , BbTT , BbTt , BbTt , BBTt , BbTT , BBTt , Bbtt , BBtt , BbTt , BbTT , bbTt , BbTt , bbTT.</h2><h2> d. 12:1:1:2</h2>

Explanation:

As given Block color is dominant over chesnut color, so B is dominant over b.

Chestnut color=bb ;

Trotting gait is dominant over pacing gait, so T is dominant over t .

Pacing gait=tt

Now; cross between

(a) homozygous black, pacing gait is= BBtt; and horse homozygous for chestnut color, trotting gait is= bbTT

BBtt x bbTT

gametes are ; Bt and bT,

Progeny are BbTt, BbTt,

All progeny will be BbTt heterozygous Black color and heterozygous trotting gait

b. a cross is made between two horses, both of who are heterozygous black trotter = BbTt X BbTt

Possible gametes of each parent are;

Parent 1: BT bt Bt bT

Parent 2: BT bt Bt bT

c. Punnett square and all the possible gene combinations that results are;

Cross between these gametes

BT bt Bt bT

possible gene combinations ; BBTT , BbTt , BBTt , BbTT , BbTt , BbTt , BBTt , BbTT , BBTt , Bbtt , BBtt , BbTt , BbTT , bbTt , BbTt , bbTT.

d. expected phenotype ration of the offspring.

Black color and trotting gait horse 12: chestnut and trotting gait horse 1: Black color pacing gait horse 1: chestnut and trotting gait horse 2.

so 12:1:1:2

A patient suffering from breast cancer chooses to undergo surgery. Doctors remove the breast where the tumor is. However, doctor

-Dominant- [34]

Answer:

The correct answers are: A single diseased cell can multiply into a new tumor; cancer cells can travel through the blood and spread into new areas; many cancer cells multiply so fast that new tumors can form.

Explanation:

Cancer is the term that groups different conditions that have all one thing in common: there's an abnormal cell growth that can potentially irradiate to other parts of the body.

A single diseased cell can develop a tumor, because this abnormal cell has the capacity to replicate so fast and, of course, transmit its abnormality to every other cell that it generates.

These abnormalities occur because there is some sort of damage in the DNA of a cell, which most of the time is detected by the body and eliminated - but when it's not, the cell quickly multiplies itself and generates a tumor. The difference between a benign tumor and cancer is that cancer can spread through the body and a benign tumor can not.

Cancer is very dangerous and potentially fatal if not treated fast because it can travel through the bloodstream or the lymphatic system and invade other organs, causing metastasis.

There's a lot of research being done on how to cure cancer, but the disparities in every different type of cancer make finding the solution much harder. Nowadays, depending on the type of cancer and the stage where the cancer is, this condition can be treated with radiotherapy, chemotherapy, or surgery.
