Regarding horizontal gene transfer between bacteria by conjugation, transduction, or transformation:
Mice21 [21]

Answer:

Distinct mechanisms are used by bacteria in order to transfer the gene from one bacteria to another. These are transformation, transduction, and conjugation. Transformation refers to the process of uptaking extracellular DNA by the recipient of the other bacterial cell.  

In the process of transduction, the donor DNA gets packed within the bacteriophage and infects the recipient bacteria. In the process of conjugation, the genetic substance is transferred by the donor bacteria to the recipient via the process of mating.  

a. Of all these three mechanisms, transformation is the process that exhibits a broad range and can be easily performed in the lab. As in the process, there is a slight chance of rejection or failure due to direct compatibility between the bacteria.  

b. While the narrowest broad range is found in the process of conjugation, as in order to transfer the genetic substance between the two bacterial species, there should be a similarity between the two species so that they can mate and exchange the genetic substance in between them.

In normal skeletal muscle tissue, binding of acetylcholine to its receptors at the neuromuscular junction results in:
BARSIC [14]
<span>Answer: Opening of Na+ and K+ Explanation: Acetycholine binding opens Na+ and K+ ion channels in the receptors that allow simultaneous passage of Naâş into the muscle fiber and Kâş out of the muscle fiber. More Naâş ions enter than Kâş ions exit, which produces a local change in the membrane potential called the end plate potential. Binding of acetycholine to receptor proteins opens Na+ and K+ channels resulting in jump in resting membrane potential(RMP) from -90mV to +75mV forming an end-plate potential (EPP).</span>

Drag the tiles to the correct boxes to complete the pairs.
Darina [25.2K]

After matching each set of values of a function to the pair of points that satisfy the function, we get

1-4

2-2

3-1

4-3

(4,3) and (6.7) rate of change = 2, and initial value = -5

k= 7-3/6-4 = 2, y=2x-5

(2,10) and (5, 19) rate of change=3, and initial value = 4

k= 19-10/5-2 = 9/3 = 3, y=3x+4

(2,5) and (5.2)→ rate of change = -1, and initial value = 7.

k= 2-5/5-2 =  -3/3 = -1, y= -x+7

(2.4) and (4,3) →→ rate of change = -0.5, and initial value =5

k= 3-4/4-2 = -1/2 =-0.5, y=-0.5x+5

The set of input values and the set of output values for a function each have their own names. The domain of the function is the collection of input values. The range of the function is the collection of output values.

Correct question: Drag the tiles to the correct boxes to complete the pairs. Match each set of values of a function to the pair of points that satisfy the function. rate of change = -1, and initial value = 7 rate of change = 2, and initial value = -5 rate of change = -0.5, and initial value = 5 rate of change = 3, and initial value = 4 (4, 3) and (6, 7) arrowRight (2, 10) and (5, 19) arrowRight (2, 5) and (5, 2) arrowRight (2, 4) and (4, 3) arrowRight

If t=talk and t= short what will be the physical appearance of the offspring in the cross
qwelly [4]

Answer:

If T=tall and t=short, what will be the physical appearance of the offspring in the cross?

Explanation:

It looks like your question is incomplete, so I'll try to fill in the blanks.

The offspring will depend on the parents.  Each parent will need two alleles, so each parent would have to be TT (tall), Tt (tall) or tt (short--this is the only way to have a short individual).

Here are all the possible crosses:

TT X TT  = 100% TT (all tall)

TT X Tt = 50% TT, 50% Tt (all tall)

TT X tt = 100% Tt (all tall)

Tt X Tt = 25% TT (tall), 50% Tt (tall), 25% tt (short)

tt X tt = 100% tt (short)

Note that if there is a T present in the genotype (TT or Tt), that individual will be tall.  The only way to produce short offspring is for the both parents to have a copy of the short allele (t).
