<h2>Answer:</h2>

The result is <u>D) Mixtures</u>.

<h2>Explanation:</h2>

In science, mixture refers to substance in which two substances are joined with the end goal that every substance holds its very own compound character. Compound bonds between the parts are neither broken nor shaped. Note that despite the fact that the concoction properties of the segments haven't changed, a mixture may display new physical properties.  

The mixtures are of two types namely homogenous mixture and heterogeneous mixture. When the solute and solvent in the mixture are not identified separately, it is homogenous mixture. When it can be identified, it is called as heterogeneous mixture.

To which substance does ferredoxin transfer an electron?
Sonbull [250]

The right answer is NADP+.

Ferredoxin is an iron-sulfur protein that effects electron transfer in a large number of redox reactions in cell metabolism through Fe-S clusters whose iron cations oscillate between +2 (ferrous) oxidation states. and +3 (ferric). The first protein of this type was isolated in 1962 from the anaerobic bacterium Clostridium pasteurianum. A chloroplast-specific ferredoxin is involved in the cyclic and noncyclic photophosphorylation reactions of photosynthesis. In non-cyclic photophosphorylation, ferredoxin is the ultimate electron acceptor and reduces NADP + under the action of ferredoxin-NADP + reductase (EC 1.18.1.2) with FAD and a flavin group as cofactors:

2 ferredoxin- [Fe (2+) Fe (3+) S2 (-2)] + NADP (+) + H (+) ==> 2 ferredoxin- [Fe3 (+2) S2 (-2)] + NADPH .

Charlie lifts a box with a force of 500 N and sets it on a table top 1.2 m above its starting position. Lauren pushes an identic
astra-53 [7]

Answer:

Explanation:

Workdone is the force applied to move a body in a specified direction.  

  Work done  = Force x distance

For first box;

          Work done  = 500 x 1.2  = 600J

For the second box = 500 x 5  = 2500J

Lauren did more work compared to Charlie because he move the box through a larger height which is the distance in this scenario.

The LMand LNalleles at the MN blood-group locus exhibit codominance. Give the expected genotypes and phenotypes and their ratios
Dmitry [639]

Answer:

Please find the expected genotypes and phenotypes of the progenies of each cross below.

Explanation:

In the MN blood-group locus of the gene, alleles LM and LN exhibit codominance i.e one allele is not dominant or recessive to the other, hence, they are both expressed when they occur in a heterozygous state (MN).

Considering the following crosses (find the punnet square attached);

a)LMLM x LMLN - The progeny are LMLM and LMLN in the genotypic ratio 1:1. Phenotypic ratio is Blood type M (1) : blood type MN (1)

b) LNLN x LNLN - The progeny are all LNLN offsprings with a phenotypic and genotypic ratio 4:0. All offsprings will have a blood type N (4)

c) LMLN x LMLN - The progenies are LMLM, LMLN and LNLN in the genotypic ratio 1:2:1 respectively. The phenotypic ratio is Blood type M (1) : L

Blood type MN (2) : Blood type N (1)

d) LMLN x LNLN - The progeny are LMLN and LNLN with genotypic ratio 1:1 and phenotypic ratio blood type MN (1) : blood type N (1)

e) LMLM x LNLN - The progeny are all LMLN offsprings with penotypic ratio blood type MN (4)
