Answer:

The correct answer is A  bacteriophages inject only DNA into the bacteria.

Explanation:

Bacteriophages are a specific type of virus that infect bacteria.During the course of infection bacteriophage releases an enzyme known as lysozyme which creates a hole in the cell wall of the bacteria.

   After doing that(creating a hole) bacteriophage inject its DNA inside the bacterium.

   The injected DNA undergo gene expression by utilizing the gene expression machinery of bacteria which ultimately result in the formation of coat protein.The DNA is then packed within the coat protein to form progeny phages.The progeny phages then disrupt the cell wall and get released from the bacterium in search of a new host.

Some synovial joints contain special crescent-shaped pads that provide additional shock absorption, and provide for a better fit
Ksivusya [100]

Answer:

menisci

Explanation:

Some synovial joints such as that of knees have crescent-shaped pads. These pads are made up of fibrocartilage and are present between the articular surfaces of the bones. These cartilaginous pads are attached to the fibrous capsule and are called articular discs or menisci.  

The function of the menisci is to serve in shock absorption and minimize the wear and tear of the joint. Meniscus also allows the articulating bony surfaces to fit properly and facilitate an adaptable surface for combined movements. Meniscus serves to distribute the weight over a greater contact surface and thereby makes the joint stable. It also spreads the synovial lubricant across the articular surfaces of the joint.

A pea plant with round seeds has the genotype rr. if you cross this plant with a wrinkled-seed plant, genotype rr, what is the p
Lapatulllka [165]
I think you wrote this wrong? Is it not round rr vs wrinkled RR?? I'll answer it with that assumption:

You are crossing a rr with an RR:
You only get Rr back so they will phenotypically be all wrinkled

If you are crossing rr with an Rr (so a heterozygote wrinkled):
50% will be Rr (wrinkled)
50% will be rr (round)
