On a scratch sheet of paper, complete the Punnett square of the cross between two heterozygous red-eyed flies (Rr). What color eyes will the offspring have?
Answer:
75% red, 25% other color (brown?)
Explanation:
A cross between two heterozygous red eye flies (Rr x Rr)
R r
R RR Rr
r Rr rr
The possible genotypes are RR, Rr, and rr. There are two possibilities of Rr.
Since the heterozygotes have red eyes, the red eye allele must be dominant. Therefore, RR and Rr genotypes will all have red eyes. That means 3/4 (75%) of offspring will have red eyes. 1/4 25% are h0m0zygous recessive (rr), and will therefore have the other eye color (question doesn't mention which colour this is, it is likely brown)

How do you know something is dead
Is this without equipment?
Depending on what organism you are talking about, animals that can be seen with the unaided eye you can tell that they are dead by studying their bodily movements such as the rise or falling of their chest.
Plants with the unaided eye, the best indicator is to take a branch or piece off and study the insides color, if it is green then mostly likely they are alive.
Now microscopic organisms are harder to say, it depends on what you are referring to.

How many chromosomes will be found in
each of the two new cells formed as a result
of mitotic cell division?
23 pairs of chromosomes will be found in each of the two new cells formed as a result of mitotic cell division.
WHAT IS MITOSIS:
Mitosis is a kind of cell division that results in the formation of two daughter cells with the same number of chromosomes as the parent cell. Mitosis is used for growth and tissue repair in living organisms. In mitosis, a parent cell divides into two new daughter cells, however, each cell possess the same number of chromosomes as the parent. In a somatic human cell, there are 23 pairs of chromosomes (46 chromosomes). If this cell undergoes mitotic division, then, there will be 23 pairs of chromosomes in each cell formed.Learn more: https://brainly.com/question/3327479?referrer=searchResults

Removing a specific group of trees within a small area over a long period of time is
a. clearcutting
b. seed tree cutting
C. group selection
d. single tree selection
Answer:
C. group
Explanation:
Removing a specific group of trees within a small area over a long period of time is group selection. The correct option is C.
What is group selection?A quantitative definition of group selection is when the average group fitness is greater or less than the mean of the fitness values of the individual members.
Another definition of group selection is when features evolve in accordance with the fitness (survival and reproductive success) of groups.
The conclusion was that although group selection is theoretically feasible, in practice it almost always favors one group over another.
Group selection is the long-term removal of a certain group of trees in a constrained region. In a clearcut, all the trees in a specific region are taken out at once.
The removal of shelterwood cutting clears an area's also clears land cleared for shelterwood cutting, which also involves cutting downing shelterwood cutting, but it is a completes a method of clearing
Thus, the correct option is C.

What is the use of reverse transcriptase?Reverse transcriptase enzyme has been generally used by the retrovirus for their genome replication. This enzyme has been discovered by the Howard tenim.
Reverse transcriptase enzyme generates the complementary DNA from the mRNA template by the process of reverse transcription. The presence of RNase H, RNA-dependent DNA polymerase and DNA-dependent DNA polymerase activity enable the enzyme to convert the mRNA into DNA.
The position of the mRNA is to carry protein facts from the DNA in a cell's nucleus to the cellular's cytoplasm (watery interior), where the protein-making machinery reads the mRNA sequence and translates every three-base codon into its corresponding amino acid in a growing protein chain.
Therefore, The mRNA sequence will best match the section of DNA shown below is C-U-A-G-G-A. Thus, option C is correct.
