Answer:
The answer is "[tex]\bold{4.0 \times 10^7 \ \frac{CFU}{mL}}[/tex]"
Explanation:
The very first thing we must do is figure out where the plate was really a countable sheet. By default, at least 30 and 300 colonists must have been on a computable plate. It is deemed incorrect beyond and below this range. We also will pick the studded 0.25 size, leading towards 72 and 65 colonies. Now calculate the double average.
[tex]\to 72+ \frac{65}{2} = 68.5[/tex]
We need to calculate its dilution factor for both the second item. Increase for all of this
All of the dilutions you also made:
[tex]\to \frac{7}{17} \times \frac{1}{60} \times \frac{1}{1000} \\\\= \frac{7}{1020000}\\\\= 6.8 \times 10^{-6}[/tex]
[tex]\to \frac{14 \ ml \ soup}{14 \ ml} + 20\ mL\\\\[/tex]
[tex]\to \frac{CFU}{mL} = \frac{Colonial \ number}{Dilution \ Factor \times Volume \ plated}\\\\[/tex]
[tex]= \frac{68.5}{6.8 \times 10^{-6} \times 0.25 \ mL} \\\\ = 4.0 \times 10^7[/tex]

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.

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.

Light Microscope:The light microscope is an instrument for visualizing fine detail of an object. It does this by creating a magnified image through the use of a series of glass lenses, which first focus a beam of light onto or through an object, and convex objective lenses to enlarge the image formed.The resolution of the light microscope cannot be small than the half of the wavelength of the visible light, which is 0.4-0.7 µm. The resolution of a light microscope is limited by the wavelength of light. Resolution is a somewhat subjective value in optical microscopy because at high magnification an image may appear unsharp but still be resolved to the maximum ability of the objective.Thus, statements 3 and 4 are correct. Therefore option C is right choice.

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.What can a fertilized egg grow into?

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.

Explanation:
Section 2: Conduct internet research on your selected ecosystem to help you generate a list of three criteria and two constraints. Your criteria and constraints should consider relevant factors to the problem, such as costs, reliability, safety (to humans and wildlife), human needs, environmental impact, local biodiversity, and the aesthetics of the area. List the criteria in order of most to least important and assign each to a related sub-problem. In the rationale column, explain why you placed your criteria in the order you selected.
Answer:
Constraints:
Funding
Protective equipment
Research
Installation
Criteria
Fertilizers
Rationale:
This is a big deal being that fertilizers are needed to help plants experts are still looking for ways to knock down the amount used.
Which Sub-Problems does this criteria address?
The main environmental problem associated with fertilizer use is contamination of water with nitrates and phosphates. The nitrogen from fertilizers and manures are eventually converted by bacteria in the soil to nitrates. ... High nitrate levels in drinking water are considered to be dangerous to human health.
Criteria:
Human Waste
Rationale:
Human waste is a large problem and the government is trying to stop the public from disposing of it.
Which Sub-Problems does this criteria address?:
Globally, almost 80 percent of the world's wastewater flows back into the ecosystem without proper treatment. This means that almost a quarter of people drink water contaminated with human waste, according to United Nations Water. That incubates deadly diseases, including cholera, dysentery, typhoid and polio.
Criteria:
Oil
Rationale:
Oil is needed for just about everything but it is very costly when it comes to the environment.
Which Sub-Problems does this criteria address?
Oil spills have a devastating effect on the environment, ruining habitats and killing the organisms that live there by sticking to them, destroying their food sources and poisoning them. Additionally, oil hurts the economy by harming the fishing industry, as well as other trades that rely on the ocean.
