Answer:

The correct answer is - reduction by accepting an electron from NADH.

Explanation:

During fermentation, the conversion of the pyruvate into lactic acid takes place which is a part of the anaerobic process. This process required a reducing agent to accept the electron by pyruvate and convert it to lactic acid.

Pyruvate + NADH → Lactic acid + NAD+

NADH oxidized again for the glycolysis process in anaerobic conditions.

In garden peas, the yellow seed trait is dominant over green seeds. Also, the round seed trait is dominant over the wrinkled-see

Darina [25.2K]

Answer:

405 individuals will be yellow and round seeded.

Explanation:

Available data:

the yellow seed trait is dominant over green seeds
round seed trait is dominant over the wrinkled-seed trait
These genes are on separate chromosomes

Let´s name the seed color genes Y, and the seed shape gene R

Y is the dominant allele for seed color expressing yellow

y is the recessive allele for seed color expressing green

R is the dominant allele for seed shape expressing round

r is the recessive allele for seed shape expressing wrinkled

Cross: between two plants that are heterozygous for both traits

Parental) Yy Rr x Yy Rr

Gametes) YR yR Yr yr YR yR Yr yr

Punnet Square) YR yR Yr yr

YR YYRR YyRR YYRr YyRr

yR YyRR yyRR YyRr yyRr

Yr YYRr YyRr YYrr Yyrr

yr YyRr yyRr Yyrr yyrr

F1) 720 individuals

9/16 yellow and round seeded individuals, Y-R-

3/16 green and round seeded individuals, yyR-

3/16 yellow and wrinkle seeded individuals, Y-rr

1/16 green and wrinkle seeded individuals, yyrr

Note: the "-" symbol in the phenotypes means that there it could be either a dominant or recessive allele.

If 720 is the total number of individuals in the F1, then:

16 possible genotypes ---------- 100% of the progeny -------- 720 individuals

9 yellow and rounded----------- 56.25% ----------------------------405 individuals

3 green and rounded-------------18.75%------------------------------135 individuals

3 yellow and wrinkled-------------18.75%------------------------------135 individuals

1 green and wrinkled--------------6.25%-------------------------------45 individuals

Plants maintain homeostasis by ____. 1) opening and closing stomata. 2) converting excess sugar molecules to a lesser number of

Nuetrik [128]

D)all of the above

Homeostasis is the property of a system, either open or closed, that regulates its internal environment and tends to maintain a stable, constant condition within an organism. (Eg controlling amount of sugar in the bloodstream, keeping waste levels at acceptable levels.) 

Opening and closing stomata controls the gas levels within the plant. 
Converting excess sugar molecules to a lesser number of starch molecules regulates sugar levels. 
Excreting waste through the cell membrane prevents waste build-up.

In a certain breed of dogs, black hair is dominant and brown hair is recessive. If two parents are heterozygous for black hair,

Bezzdna [24]

There is a 3/4 chance their offspring will be black. If you make a Punnett's (I hope that's how you spell it) square then you will find that one offspring will be homozygous for black hair, two will be heterozygous with black hair, and one will be homozygous with brown hair. Therefore, there's a 3/4 chance the offspring will have black hair. Hope this helped!
