The map of a walking trail is drawn on a coordinate grid with three points of interest. The trail starts at R(−2, 4) and goes to S(3, 4) and continues to T(3, −1). The total length of the walking trail is ___
Answer:
The total length will be "10 units". A further explanation is given below.
Explanation:
The given points are:
R(−2, 4)
S(3, 4)
T(3, −1)
On applying the distance formula,
⇒ [tex]RS=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
⇒ [tex]=\sqrt{(3-(-2))^2+(4-4)^2}[/tex]
⇒ [tex]=\sqrt{(3+2)^2+(0)^2}[/tex]
⇒ [tex]=\sqrt{25}[/tex]
⇒ [tex]=5 \ units[/tex]
and,
⇒ [tex]ST=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
⇒ [tex]=\sqrt{(3-3)^2+(-1-4)^2}[/tex]
⇒ [tex]=\sqrt{0+(-5)^2}[/tex]
⇒ [tex]=5 \ units[/tex]
Now,
The total trail length will be:
= [tex]RS+ST[/tex]
= [tex]5+5[/tex]
= [tex]10 \ units[/tex]

The best demostration that applies to Newton's Third Law of motion would be D) When you walk your foot pushes down on the ground while the ground pushes back on your foot.
Explanation:Newton's Third Law states that for every action, there is an equal and opposite reaction. This is actually explains that forces come in pairs and forces are an interaction between two objects. As per the correct option given in the question explains Newton’s Third Law.
When you walk your foot (say object A) pushes down on the ground while the ground (say object Q) pushes back on your foot with the same force but in the opposite direction.
Place the Polymerase Chain Reaction events listed below in the order in which they occur. - Double-stranded DNA is produced - DNA sample is heated - Test tube with DNA sample is placed in machine - Taq polymerase initiates DNA synthesis - DNA denatures
Answer:
1- Test tube with DNA sample is placed in machine
2- DNA sample is heated
3- DNA denatures
4- Taq polymerase initiates DNA synthesis
5- Double-stranded DNA is produced
Explanation:
The Polymerase Chain Reaction (PCR) is a technique widely used in molecular biology laboratories in order to produce many copies of a specific DNA sample. Thermocyclers are machines designed for a cyclic temperature change of the PCR. First, an initial denaturation step where DNA sample is heated to separate the double-stranded DNA into two single strands. Subsequently, 20-40 PCR cycles are repeated to produce millions of copies of a specific DNA sequence. There are three steps in each PCR cycle: 1-Denaturation to 94–98 °C (DNA strands are separated), 2-Annealing to 50–67 °C (primers bind to each DNA strand on the opposite ends of the DNA strands to be copied) and 3-Extension to 75–80 °C (Taq polymerase initiates the synthesis of complementary DNA strands).
Your professor tells you that there are 32 possible genotype combinations for an organism. How many genes does the organism have?
Answer:
The organism will probably have 16 Genes
Explanation:
Genetics is the part of science managing the standards of variety and legacy in creatures and plants. The investigation of hereditary qualities gives us more prominent comprehension of how we can decide the probability of acquiring certain characteristics and clarifies and anticipate examples of legacy in family lines.
Each living life form is comprised of a wide range of qualities, or recognizing attributes, that make it a special person. Certain characteristics in plants and creatures may have characteristics that individuals need to advance.

E. coli strain B is doubly infected with two rII mutants of phage T4. 0.2 ml of a 108 dilution of the progeny is plated on E. coli B and 0.1 ml of a 104 dilution of the progeny is plated on E. coli K. 16 plaques appeared on strain B, 400 on strain K. Calculate the recombination frequency between these two mutations.
To Find :
The recombination frequency between these two mutations.
Solution :
Formula of calculating recombination frequency is :
[tex]R.F = \text{Number of mutations}\times \dfrac{\text{number of k plaques} \times D.F }{\text{Volume used}}\times \dfrac{Volume'}{\text{Number of B plaques} \times D.F' }}[/tex]
Putting all given values in above equation, we get :
[tex]R.F = \dfrac{2\times 400\times 0.2 \times 10^4}{16\times 0.1\times 10^8}\\\\R.F = 0.01[/tex]
Therefore, the recombination frequency between these two mutations is 0.01 or 1 %.
Given:
No. of mutation = 2Volume, [tex]V = 0.1[/tex][tex]V'= 0.2[/tex]
k plaques = 400The formula:
→ [tex]R.F = No. \ of \ mutations\times \frac{No. \ of \ k \ plaques\times D.F }{Volume}\times \frac{Volume'}{No. \ of \ B \ plaques\times D.F'}[/tex]
By putting the values in the above formula, we get
→ [tex]= \frac{2\times 400\times 0.2\times 10^4}{16\times 0.1\times 10^8}[/tex]
→ [tex]= \frac{160\times 10^4}{1.6\times 10^8}[/tex]
→ [tex]= 0.01[/tex]
Thus the solution above is the right approach.

Rocks and minerals activity Reflection questions:
1. Describe the ways mining in the real world can affect society, ecosystems, and the environment of a specific region.
2. Using your answers to the question above, list the criteria you believe should be addressed by land reclamation. Prioritize your criteria by order of importance. Explain the order you selected for your criteria.
3. Complete redamation of mined land is the solution you practiced in this cookie mining lab. What reasoning supports this solution as one that will provide the largest benefits and least costs to society and the environment ?
4. Legislation requiring the reclamation of the land makes mining more expensive. How important is this constraint to achieving complete reclamation of mined land?
Answer:
1. Across the world, mining contributes to erosion, sinkholes, deforestation, loss of biodiversity, significant use of water resources, dammed rivers and ponded waters, wastewater disposal issues, acid mine drainage and contamination of soil, ground and surface water, all of which can lead to health issues in local.. 2.Mining in the real world can affect society, ecosystems, and the environment of a specific region because all the minerals that you are looking for won't be right where you want them to be. It is not going to be in the same area. Instead, it will be scattered throughout the mines and you will have to search for them. 3.Students act as mining engineers and simulate ore mining production by using chocolate chip cookies. They focus on the cost-benefit analysis of the chocolate ore production throughout the simulation, which helps them understand the cost of production. As students “mine” with tools such as paperclips and toothpicks, they keep records of their costs—land (cookie), equipment used, cookie size before and after production, and time spent. While the goal is to make as much profit as possible, other costs and goals are taken into consideration—as in real-world mining engineering. For example, mining engineers also consider the resulting amount of destruction to the lithosphere when deciding the best method to obtain ore. Thus, a line item for land reclamation cost is included from the beginning. A provided worksheet serves as a profit and loss statement. 4.Mine reclamation is the process of restoring land that has been mined to a natural or economically usable state. Although the process of mine reclamation occurs once mining is completed, the planning of mine reclamation activities occurs prior to a mine being permitted or started.
Explanation:
i don't have a explanation but i hope this helps
The extraction of minerals or other geological elements from the earth is known as mining.
How does mining affect society, ecosystems, and the environment?Society: Mining increases social conflicts, causes relocation of the community, affects the health of humans and animals and causes loss of land. However, it helps increase economic growth. Ecosystem: Mining adversely affects biodiversity and destroys the habitat.Environment: Mining causes erosion, sinkholes, deforestation, overuse of water resources, waste disposal issues, acidification of soils and water bodies, and their contamination.What is land reclamation?It is the process by which the mined lands are filled, thereby producing land that can be used. They can be used to restore the environment. However, the ecosystem and society's restoration takes a long time.
Is it beneficial?While the land that cannot be used now has been restored, the materials that have been used have been taken from a source, and that can lead to changes in the ecosystem at the source.
What is the reasoning that supports land reclamation as the solution?The goal is to produce as much profit as feasible. When determining the optimum approach to collecting ore, mining engineers, take into account the amount of lithosphere destruction, and hence, from the start, land reclamation costs are included.
What is the role of mine reclamation legislation?It ensures that land reclamation activities are planned before a mine is licensed or started.

Why is the cell like a city?
Answer:
The cell is basically like a city because there are different parts of the cell that work together to keep a system running, therefore incredibly similar to a cell. There are parts to the cell such as the vacuole which acts as the storage for a cell, like the storeroom or bank in the city, and the lysosome which cleans up and recycles for the cell in away, acting as the recycle center or such for a city. Just like these few cell parts, there are many other parts which each have their respective "role" to functioning as a "city", and for those reasons a cell is like a city.

A: predict percentage of offspring with a trait
B: predict genotypic probabilities
C: track inherited traits through generations
D: identify the genotype of parents
Answer:
A pedigree chart is used to track inherited traits through generations (option C).
Explanation:
A pedigree chart is a graphical representation, similar to a family tree, showing specific traits present in parents, children and relatives. It is a diagram commonly used in genetics.
A certain phenotype, product of genetic traits, is represented in a pedigree chart by pre-established symbols, which is useful for tracking inherited traits through generations.
The other options, predict percentage of offspring with a trait , predict genotypic probabilities or identify the genotype of parents require a Punnett square to be identified.Answer:

There are three alleles for the ABO blood group in humans. Why are there only two alleles normally present in any individual?
1. The alleles for the ABO blood group always segregate independently during meiosis.
2. Each parent contributes only one allele for the ABO blood group to the offspring
3. Every gene for the ABO blood group must be recessive.
4. The alleles that determine the ABO blood group are on the X-chromosome.
Answer:
2. Each parent contributes only one allele for the ABO blood group to the offspring
Explanation:
Humans are diploid organisms, which means that our cells have two copies of the same gene. These copies are called alleles. We inherit one allele from each parent.
Just like most of our traits, we inherit our blood group from our parents. There are three alleles that determine our blood group: A, B, and O. We can get only two of them, though. Whether our blood group is A, B, AB, or O will depend on the combination of the alleles we inherited.
When Lake Mendota was completely covered with algae, biologists used the concept of trophic cascades to solve the problem by introducing predatory fish. When they did this, a\an ________ in predatory fish caused a\an ________ in plankton feeding fish, which resulted in a\an ________ in\ herbivorous plankton with a consequent ________ in algae. Group of answer choices increase; increase; increase; decrease increase; increase; decrease; increase decrease; increase; increase; decrease increase; increase; decrease; increase increase; decrease; increase; decrease
Answer:
increase; decrease; increase; decrease
Explanation:
When Lake Mendota was completely covered with algae, biologists used the concept of trophic cascades to solve the problem by introducing predatory fish. When they did this, an increase in predatory fish caused a decrease in plankton feeding fish, which resulted in an increase in herbivorous plankton with a consequent decrease in algae.
With the introduction of predatory fish, a decrease in the population of zooplankton-eating fish would occur due to predation by the newly introduced fishes. This will cause the population of zooplankton to thrive or increase.
Zooplanktons feed on algae. Hence, an increase in their population will put pressure on the alga in the ecosystem and cause a decrease in their population.

Explanation:
Enzymes that work in the stomach must adjust to the unique environment by being able to function in an acidic environment.
Which enzyme would most likely function in the stomach?One or more polypeptide chains of amino acids make up a big protein enzyme molecule. The unique protein folding patterns, which are crucial for enzyme specificity, are determined by the amino acid sequence.
Pepsin and rennin are the two primary enzymes found in gastric juice. While rennin coagulates the soluble milk protein, casein, into an insoluble curd, which is then attacked by pepsin, pepsin breaks down proteins into short polypeptide chains. Pepsin is produced by the chief cells of the stomach as pepsinogen, an inactive zymogen.
