Answer:

The light reflection is the returning back of light waves in the same medium on meeting a reflecting surface, and the surface at which the reflection takes place is called the reflecting surface, The light reflection is classified according to the nature of the reflecting surface into the regular (uniform) reflection, and the irregular (non-uniform) reflection.

First of all, this was a bit garbled up, so it is sort of incomplete.

You gave me a total of 43 words, and I only counted 41 slots on the crossword graph itself, which is problematic.

I got as far as I could, but some of the words either weren't provided, or the spaces were made incorrectly for the length of these words.

Across:
2. (black / pitch)
7. conservation
9. radiation
12. crest
13 ?
14. whatever you wrote
15. dense
18. ? (radiant)
19. ? (radiant)
20. amperes
23. medium
25. density
26. ?
30. resistance
31. (pitch / black)
34. voltage
35. insulator
38. amplitudes
39. thermal
40. ?
41. wavelength

Down:
1. electromagnetic
3. (conduction/ convection)
4. (convection/ conduction)
5. (current/ radiation)
6. heat
7. chemical
8. transverse
10. energy
11. nuclear
12. circuit
16. electrical
17. electrons
21. mechanical
24. source
28. ?
32. rise
33. MRS CHEN
34. volts
36. sound

Eukaryotic sexual life cycles show tremendous variation. Of the following elements, which do ALL sexual life cycles have in comm

larisa [96]

Answer:

II. meiosis

III. fertilization

IV. gametes

Explanation:

Gamete formation and fertilization are the processes performed by all the sexually reproducing organisms. Gametes are the cells that are formed in the male and female sexual organs of these organisms. Formation of gametes occurs by meiosis and therefore, the gametes of a diploid organism are always haploid.

Male and female gametes fuse during the process of fertilization and form the zygote which in turn divide repeatedly to produce an embryo. For instance, sperms and eggs are the male and female gametes that are formed in testes and ovaries of male and female human individuals respectively. The fusion of sperm and egg produces a zygote that finally develops into a young one.

In a population of plants, the allele for long stems is completely dominant over the allele for short stems. If 35% of the popul

KatRina [158]

Assumptions:
1. Equilibrium has been reached for the allele proportions
2. Absence of evolutionary influences such as mate choice, mutation, selection, genetic drift, gene flow and meiotic drive.

Defining L=long stem, l=short stem, and L is dominant over l.
f(x) = frequency of allele x (expressed as a fraction of population)
Then the Hardy-Weinberg equilibrium law applies:
p^2+2pq+q^2=1
where
f(LL)=p^2
f(Ll)=2pq
f(ll)=q^2

Given f(ll)=0.35=q^2, we have
q=sqrt(0.35)=0.591608
p=1-q=0.408392
=>
f(Ll)
=2pq
=2*0.408392*0.591608=0.483216
= proportion of heterozygous population

Answer: percentage of heterozygous population is 48.32%
