How many atoms of the element hydrogen are there for each atom of oxygen in the compound we know of as 'water'?

Both starch and glycogen are forms of carbohydrates. Right?

I am Lyosha [343]

Yes, you are correct. Both starch and glycogen are carbohydrates. Starch and glycogen are both complex carbohydrates because they consist of polysaccharides.

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

_______ support mangrove trees out of the water

dolphi86 [110]

The answer is b. Prop roots.

Mangroves are small trees and shrubs that live in the coastal zone. Mangrove trees must fight rough tides, huge waves, strong winds, and storms. One of adaptation is prop roots. The prop roots grow out the mangrove trunk, branches or other prop roots until they touch the ground. There they develop an underground root system. These roots serve as a support in the conditions characteristic for mangrove.
