Why would mutation of a tyrosine residue to glutamate in the intracellular portion of a growth factor receptor lead to increased tumor formation
Answer:
this mutation leads to a constitutively active state where the receptor can not be inactivated by dephosphorylation
Explanation:
Phosphorylation is a posttranslational modification that usually occurs at the side chains of serine, tyrosine and threonine residues, thereby regulating protein function. Phosphomimetic amino acids are substitutions (mutations) able to mimic the phosphorylated form of the protein, resulting in constitutive activation/inactivation of the corresponding protein. In this case, it is expected that the substitution of tyrosine to glutamate gives rise to a constitutively active state of the receptor by replacing tyrosine with a phosphomimetic residue.
What is the pH of a 2.4 x 10-5 M
OH-solution?
Answer: pH = 9.4
Explanation: in water, -log(molar concentration OH-) + -log(molar concentration H+) = 14
-log(H+) is pH
so pH = 14 - -log(OH-)
= 14 - -log(2.4*10^-5)
= 14 - 4.6
= 9.4

What patterns do you see in the similarities and differences between Hox genes in
humans and in fruit flies?
Explanation:
Hox genes are the master regulators of embryonic development for all animals, including humans, flies and worms. They decide what body parts go where. ... "We have exactly the same genes, and use them in exactly the same way," he says. "By understanding them in Drosophila, we can understand them in humans."
The study of genes is called genetics.

The F1 mother of these progeny (F2) resulted from a cross between two flies from true breeding lines (P generation). What are the genotypes of these two lines
The question is incomplete. The complete question is :
In fruit flies, the recessive pr and cn mutations cause brown and bright-red eyes, respectively (wild-type flies have brick-red eyes). The double mutant pr cn combination has orange eyes. A female who has wild-type eyes is crossed to an orange-eyed male. Their progeny have the following distribution of eye colors:
wild-type8
brown241
bright-red239
orange12

The F1 mother of these progeny (F2) resulted from a cross between two flies from true breeding lines (P generation). What are the genotypes of these two lines ?
Answer:
prprcn+cn+ and pr+pr+cncn
Explanation:
Progeny is the offspring or descendants of any animal, plant, human or a species.
In the context, it is given that the cn mutation and recessive pr in the fruit flies makes brown and bright red color eyes. And the double mutant of pr and cn combination makes orange eyes. An oragne eye males is crossed with a female having a wild type eyes. Now for this, the F1 mother of the progeny F2 which results from the cross of two flies, the genotypes is " prprcn+cn+ and pr+pr+cncn. "

Mike created the following table... what needs to be corrected
Answer:
The outer core is liquid and the inner core is solid.
Explanation:
This statement is true, the inner core is not liquid it's solid.
The outer core is liquid and the inner core is solid. The opportunity cost of 1 chair is 1/5 table for Mike and 1/3 table for Sandy.
What is cost opportunity?Opportunity cost of the next best option forgone when one alternative is chosen over other alternatives. In order to determine the opportunity cost of making chairs, divide the number of tables made for each person by the number of chairs.
Mike's opportunity cost in making one chair = 4/20 = 1/5
Sandy's opportunity cost in making one chair = 6/18 = 1 / 3
Petrifcation can be defined as the process in which the organic material of the dead living being becomes fossil by the replacement of mineral deposition in the bony, hard material. Thus, although the body components gets decomposed wiped out due to this process. The body shape of the dead organism remains the same as that was in living.
Therefore, The is liquid and the inner core is solid. The opportunity cost of 1 chair is 1/5 table for Mike and 1/3 table for Sandy.

would be best for studying cilia
Answer:
Scanning electron microscope and electron microscope.
Explanation:
Scanning electron microscope is a type of microscope which can produced the image of cilia. Electron microscope is a type of microscope would be the best for studying cilia because it has higher magnification power i. e. 10,000,000x, which able us to study different parts of cilia so we can say that electron microscope is the right choice for studying cilia.
24. Four identical rocks four four identical rocks were dropped into a stream and were
washed downstream. Which of the rocks below was prob-
ably transported the least distance.
Less distance may be traveled with grains whose sizes are greater and more erratic. This is because as a stream moves downstream, its velocity progressively diminishes, causing the big and irregular grains to settle the first, hence option 3 is correct.
How are sediments transported?Both a reduction in particle size and rounding of initially angular pieces are effects of the protracted transport of material by water and wind current. The grains get smaller and more spherical the farther they have to travel.
Erosion, transport, and deposition all result in the formation of sedimentary rocks. A sediment's grain size provides crucial details on (1) the agent that caused the erosion/transport of the sediment and (2) the current's speed.
Therefore, as a stream moves downstream, its velocity progressively diminishes, causing the big and irregular grains to settle the first, hence option 3 is correct.
