Answer:
A white colony in tetracyline plates
Explanation:
Beta-galactosidase (also known as beta-gal or β-gal), will not be produced if a gene was cloned into the Lac Z gene. It is because β-galactosidase is produced by the activation of the lacZ gene, and thereby β-gal can not be produced in the absence of this lac operon. In consequence, X-gal will not be hydrolyzed by the β-gal enzyme in a reaction that releases a blue pigment, and thus the colony will be white. In gene cloning, X-gal enables to determine whether a cell is expressing a functional β-gal enzyme, which is known as the "blue/white screening method".

Answer: B trivially easy to copy and redistribute
Explanation:
If the last pair reflects whether the organism is a male or female, which would the organism be?
Complete question:
There is a karyotype in this question, which is missing. You will find it in the attached files.
Answer:
The individual is a male.
Explanation:
In mammals, sex is determined by a pair of sexual chromosomes. Sexual chromosomes in humans and other mammals are X and Y. The females are represented by the combination of two X chromosomes, while males are represented by the combination of an X chromosome with a Y chromosome. This is, females are XX, and males are XY. When looking at the sexual pair of chromosomes in a karyotype, you can figure out which is the individual´s gender by comparing their sizes. The X chromosome is much bigger and longer than the Y chromosome.
In the shown karyotype, the last pair represents the sexual chromosomes. You can see that one of them (the one on the left) is long and express a sort of J shape, while the other chromosome (on the right) is very short and small. According to what we previously mentioned, the X chromosome is the long one on the left, and the Y chromosome is the short one on the right. This is a male individual.
Sex chromosomes are the central determinant that defines the sex of an individual. By analyzing the karyotype one can conclude the sex chromosomes and the autosomes.
The correct answer is:
The individual is male.
Reason for the answer:
In organisms like mammals, the sex of an individual is determined by sex chromosomes. Humans and many other mammals have two sex chromosomes X and Y.The females have two X chromosomes(XX), while males have one X and one Y chromosome (XY).By studying karyotype one can distinguish among the X and Y chromosomes. The X chromosome is bigger than the Y chromosome.The karyotype provided in the question represents sexual chromosomes. The chromosome present on the left is large and is J-shaped which represents the X chromosome, while the chromosome present on the right is small and depicts the Y chromosome.Therefore, the given Chromosome is the Y chromosome and represents a male chromosome.

In '57 Chevy's, the gene for having fuzzy dice (F) on the rear view mirror is dominant
over the gene for having smooth dice (f) on the rear view mirror. The genotype of a
smooth dice is -
FF
heterozygous
ff
cannot be determined
Answer:
ez i just took the test is FF pls give brainly
Explanation:
According to the scenario, the genotype of a smooth dice is ff. Thus, the correct option for this question is C.
What is a Genotype?A genotype may be defined as the ultimate combinations of alleles of those genes which are significantly taken for specific studies in order to determine some facts and knowledge.
According to the context of this question, it is clearly given that the gene for having fuzzy dice (F) on the rearview mirror is dominant over the gene for having smooth dice (f) on the rearview mirror. This means that F>f. So, it the phenotype of a recessive allele has to visualize in any organism, its genotype must carry form forms of the recessive allele.
Therefore, according to the scenario, the genotype of a smooth dice is ff. Thus, the correct option for this question is C.

- Pain, swelling, or redness where the shot was given
- Mild fever
- Chills
Feeling tired
Headache
- Muscle and joint aches"
.
A lot of us can probably state from experience feeling at least a few of these symptoms with
vaccines. I just got my flu shot on Sunday, and I personally experienced pain at the site of the shot,
tiredness, and muscle and joint aches. (These symptoms were mild and completely worth reducing
the risk of contracting and spreading influenza this fall and winter.)
What's really cool is these symptoms actually serve as a sign that our immune system is at work.
Explain how these mild symptoms following a vaccine indicate our immune system is working
properly. Although we often think of how vaccines affect the third line of defense through the
creation of memory cells and production of antibodies, consider what you learned in the previous
chapter on the second line of defense and how this relates to the mild symptoms following
vaccination.

8 facts about the Geosphere
Facts:
The Geosphere is basically the insides of the earth so breaking it up into eight parts will be based on each section of it.
1. The crust is the top layer of the Earth, it consists of the water and land we see. It is a shell that lays atop or covers the Upper mantle piece.
2. The mantle is a layer between the crust and core, Earth's mantle is a rocky shell that is roughly 2,900km thick and is 84% of Earth's volume.
3. The Geosphere is the solid part of the Earth that consists of rock, soils and sediments on the surface of the Earth.
4. The core is the innermost layer of the Earth and is up to 6371km from the surface of the Earth, it consists of Nickel and Iron and are seen as main components of it.
5. The outside of the core is known as the molten core due to it mainly being liquid metal from the heat and the inner portion of the core known as the solid core.
6. Another name or term given to the Geosphere is called the lithosphere, depending on the definition they both mean the same thing but are still argued by scientists.
7. The Geosphere is in constant motion due to the tectonic plates. These plates are what causes earthquakes ,volcanoes to erupt and even tsunamis.
8.There are eight major tectonic plates making up the earth's geosphere. They are constantly moving, but usually only a few centimeters each year, this is known as continental drift.

Describe the osmotic regulation strategies of marine fish
Answer:Water will diffuse into the fish, so it excretes a very hypotonic (dilute) urine to expel all the excess water. A marine fish has an internal osmotic concentration lower than that of the surrounding seawater, so it tends to lose water and gain salt. It actively excretes salt out from the gills.

Explanation:
What evolutionary advantage might on/off signaling have over this continuously variable kind of signaling?
Answer:
Hello the options to your question is missing below are the missing options
A threshold to cause a signal is lower than in graded potentials. Graded potentials can cause a strong but single depolarization signal.
The speed of propagation is much faster as depolarization in one location causes depolarization in the neighboring ones.
Propagation of the on/off signals requires less ATPATP because the neighboring locations can depolarize each other.
The on/off signal may be propagated over long distances without any decay. Therefore, the signal is reliable.
The power of the stimulus does not matter once it triggers the signal. Therefore, different stimuli may cause the desired response.
Answer :The speed of propagation is much faster as depolarization in one location causes depolarization in the neighboring ones.
Propagation of the on/off signals requires less ATPATP because the neighboring locations can depolarize each other.
Explanation:
Some of the evolutionary advantage that on/off signaling have over this continuously variable kind of signaling are :
The speed of propagation is much faster as depolarization in one location causes depolarization in the neighboring ones.Propagation of the on/off signals requires less ATPATP because the neighboring locations can depolarize each other.why are there usually several types of pigments present in cloroplast
