A geneticist is studying two traits in corn: kernel color and kernel appearance or ‘shine'. The R/r alleles determine kernel color (R – purple color; r – yellow color). The W/w alleles determine kernel ‘shine' (W – waxy; w – dull). The geneticist crosses two corn plants that are Rr Ww and Rr ww . What phenotypic ratio is expected from these two parents?
Answer:
Purple, waxy (R_W_) = 6
Purple, dull (R_ww) = 6
Yellow, waxy (rrW_) = 2
Yellow, dull (rrww) = 2
Phenotypic ratio = 3 (purple, waxy) :3 (purple dull) :1 (yellow waxy) :1 (yellow dull)
Explanation:
This question involves two genes coding for kernel color and kernel appearance or ‘shine in corn plants. The alleles for purple kernel (R) and kernel waxy (W) are dominant over the alleles of yellow color (r) and kernel dull (w).
According to this question, a geneticist cross two corn plants that have the genotype: RrWw and Rrww. The following gametes will be produced by each parent:
RrWw - RW, Rw, rW, and rw
Rrww - Rw, Rw, rw, and rw
Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:
Purple, waxy (R_W_) = 6
Purple, dull (R_ww) = 6
Yellow, waxy (rrW_) = 2
Yellow, dull (rrww) = 2
The phenotypic ratio expected from crossing these two parents is 3 (purple, waxy) :3 (purple dull) :1 (yellow waxy) :1 (yellow dull).

Which of the following statements is NOT correct?
O Heat energy is needed to melt ice into water.
O The most important source of water in the atmosphere is conduction from the oceans.
O Water reaches the land surface as rain or snow and is transported to the ocean by streams, rivers, and lakes.
O Liquid water from the Earth's surface is evaporated into a gaseous form and enters the atmosphere as water vapor.
Answer:
it's O n2. So, The most important source of water in the atmosphere is conduction...
Explanation:
Hope that helps! (Btw I did this test and got it correct)
The statement "The most important source of water in the atmosphere is conduction from the oceans" is not correct.
The most important source of water in the atmosphere is evaporation.
What is evaporation?Evaporation is a process through which a liquid transforms into a gas. It's a type of vaporization that occurs specifically at the surface of a liquid. Whenever a liquid gets heated the molecules, near its surface gain energy. Become more active. These energetic molecules tend to collide with each other resulting in some of them escaping from the liquids surface and entering the gas phase.
In terms of sourcing water for the atmosphere, evaporation of water from the Earths surface plays a role. Although water vapor does come from the oceans through conduction it's not the source that we rely on.

A scientist performed an experiment during which she measured the energy transferred in each step of her experiment. The total quantity of energy transferred in all of the steps was less than the amount she measured at the beginning. What is the most likely explanation for this result?
Answer:
Option D
Explanation:
The complete question is
A scientist performed an experiment during which she measured the energy transferred in each step of her experiment. The total quantity of energy transferred in all of the steps was less than the amount she measured at the beginning. What is the most likely explanation for this result?
a) Energy was destroyed during certain steps in the experiment.
b) The steps in the experiment required more energy than was available
c) The experiments created energy that was then used up at a faster rate.
d) Some energy was transformed into unwanted heat or sound that was not detected
Solution -
Option D is correct
While transfer of energy through any medium, some energy is lost in the form of heat and light. This loss of energy is not accounted at the beginning of the process and hence the initial energy loss was zero. With the succession of the process energy kept loosing and hence the final energy count was low at all steps.

Transcription is the process of mRNA synthesis. It occurs in the nucleus before translation. During transcription, RNA bases pair DNA bases, replacing Thymine with Uracyl. You will find the example in the explanation.
Note: The DNA sequence is missing, so I will provide a new sequence and explain the procedure. I suggest you perform the same steps with your molecule fragment and reach the correct mRNA.
Protein synthesisProteins synthesis is done in two stages: transcription and translation. The whole process begins in the nucleus and finishes in the cytoplasm.Protein synthesis initiates in the AUG start codon -Metionin-, and ends when reaching either of the stop codons UAA, UAG, UGA. Once the new molecule is completed, it is sent to its final destiny.Transcription:The first step before protein arrangement is to synthesize messenger RNA, mRNA. This is the transcription process and occurs in the nucleus. When the DNI molecule separates into two strands to form the transcription bubble, we can identify two separate segments: coding strand and template strand. The coding strand goes in direction 5' to 3', while the complementary strand -template strand- grows in direction 3' to 5'. This last segment is the one that is going to be complemented by the mRNA. It is the template strand. A template DNI strand is read in direction 3'→ 5' to build the mRNA molecule that grows in direction 5'→ 3'.During transcription bases forms pairs. RNA replaces Thymine with Uracyl, so pairs are as follows,DNA mRNA
Adenine pairs Uracyl, Thymine pairs Adenine, Guanine pair Cytosine, Cytosine pair Guanine.Translation:
Translation occurs in the cytoplasm. During translation, rRNA reads mRNA in 5' to 3' direction, and tRNA adds the correct amino acid to the growing chain. The first extreme to be translated carries the amino-terminal group, while the other extreme carries the carboxy-terminus group.ExampleWe will consider for this example the following DNA template strand.
DNI strand ⇒ 5'-TAGAACGCCTCGAAATTTCATACT-3'
Transcription
template DNI strand ⇒ 5'-TAGAACGCCTCGAAATTTCATACT-3'
mRNA ⇒ 3´-AUCUUGCGGAGCUUUAAAGUAUGA- 5´
The new mRNA strand is
mRNA ⇒ 3´-AUCUUGCGGAGCUUUAAAGUAUGA- 5´
Once the mRNA synthesis is over, the molecule leaves the nucleus and proceeds with translation in the cytoplasm.

Chromosome 11 is one of the 23 pairs of chromosomes in humans. Humans normally have two copies of this chromosome. Chromosome 11 spans about 135 million base pairs (the building material of DNA) and represents between 4 and 4.5 percent of the total DNA in cells.
Show different life cycle patterns with the help of near labelled diagram
Answer:
The life cycles of all sexually reproducing plants follow a pattern of alternation between a haploid, sexual generation called gametophyte with a diploid, asexual generation called sporophyte.
This phenomenon of alternation between gametophyte (n) and sporophyte (2n) in the life cycle of a plant is called alternation of generations (Hofmeister, 1851).
Alternation of generations is of two types- isomorphic and heteromorphy. In isomorphic (or homologous) type both the alternating generations are morphologically similar, while in heteromophic (or heterologous) type of alternation of generations both the generations of life cycle are morphologically dissimilar.
