How does removing the "overburden" during coal extraction affect the environment?
Answer: Strip mining eliminates existing vegetation and alters the soil profile, or the natural soil layers.
Explanation:
Mining disturbs and may even destroy the beneficial micro-organisms in the topsoil. Soil also may be damaged if reclamation operations mix the topsoil with subsoils, diluting matter in the surface soil.
How do you create a dichotomous key?PLEASE WRITE IT GOOD BC I HAVE A TEST TOMORROW
Answer:
In the field of biology, classification plays a major role. With new species being discovered every day, it’s important to have techniques in place to identify and classify them. One such tool is the dichotomous key. It helps identify organisms by directing the user to look at the known organisms.
Explanation:
What is a Dichotomous Key
What is a Dichotomous KeyStudents and professionals use the dichotomous key to identify and classify objects (i.e. people, animals, plants, bacteria, etc.) into specific categories based on their characteristics. It’s the most commonly used form of classification or type of identification key used in biology as it simplifies identifying unknown organisms.

By correctly selecting the right choice at each stage, the user will be able to identify the name of the organism at the end. The further you divide the key, the more you learn about the specimen you are trying to identify.

Most often, they are used to identify plant and animal species, although it can be used to classify any object that can be identified by a set of observable characteristics.

How is the DNA sequence AATTA replicated in a new strand during semiconservative replication?
Answer:
According to the semi-conservative DNA replication, the AATTA sequence is transcribed into a new strand as TTAAT, taking into account the complementarity of nitrogenous bases.
Explanation:
Semi-conservative DNA replication means that two molecules are obtained from a double-stranded DNA molecule, each with an original strand and a new strand.
The DNA is composed of sequences of nitrogenous bases, which are adenine (A), guanine (G), thymine (T) and cytosine (C). The bases of one chain are matched with the bases of another, according to the complementarity of nitrogenous bases, where:
Adenine is complemented with Thymine A=TGuanine is complemented with Cytosine G≡CThen, for the sequence AATTA of the strand DNA mold, the sequence on the new strand would be complementary, i.e., TTAAT.

The recombination frequency between linked genes A and B is 40%, between B and C is 20%, between C and D is 10%, between C and A is 20%, and between D and B is 10%. What is the sequence of the genes on the chromosome?
Answer:
ACDB (or BDCA)
Explanation:
The linked genes A and B have a greater frequency of recombination (40%) and therefore they are found furthest away on the chromosome. Conversely, the smaller distance is between D and B, which exhibit a lower frequency of recombination (10%), while C is localized at the same physical distance of both A and B (20%), so the physical map is ACDB.
Physical map:
A--------C-----D-----B

A group of students wants to build a ramp to move boxes from the floor up to a stage. How can the students reduce the amount of effort needed to push the boxes up the ramp?
Question 8 options:
by making the ramp as long as possible
by making the ramp’s height and length equal
by building the ramp out of a lightweight material
by covering the ramp’s surface with a soft rubber mat
If students wants to reduce the amount of effort needed to push the boxes up the ramp, it is possible by making the ramp’s height and length equal, hence option 2 is correct.
Why does it take more force to move a heavy box up a ramp?If students moves a heavy box up a ramp, there is so much friction on the undersurface of the box when going up a ramp.
To reduce the amount of effort needed to push the boxes up the ramp by making the ramp’s height and length equal, in second option by making the ramp as long as possible needs more effort.
In the fourth option, by covering the ramp’s surface with a soft rubber mat, make it harder to slide up boxes.
Therefore, by making the ramp’s height and length equal, it is easier to reduce the amount of effort.

What is the substrate of enzyme 2?
What is the substrate of enzyme 3?
What is the product catalyzed by enzyme 1?
What is the starting reactant for enzyme 3? Blank 4
Answer:
anwer is down
Explanation:
A substrate is a molecule that an enzyme reacts with. The enzyme's active site, or the location where weak bonds between the two molecules can form, is loaded with a substrate. An enzyme substrate complex is formed, and the enzyme's pressures on the substrate drive it to react and become the planned reaction's result.
How does resistance, such as pesticides resistance or antibiotic resistance, develop?
Answer:
Antibiotic resistance is a consequence of evolution via natural selection. The antibiotic action is an environmental pressure; those bacteria which have a mutation allowing them to survive will live on to reproduce. They will then pass this trait to their offspring, which will be a fully resistant generation.

A few minutes of incubation at room temperature in the laboratory will inactivate HIV, but the flu virus is still active after incubating for several hours. What are the practical consequences of these findings?
Answer:
Flu virus cause more infection than HIV virus.
Explanation:
The practical consequences of these findings indicates that the flu virus has more chances to cause infection in the person due to its active nature as compared to HIV virus which is inactive after incubation. This active nature of the flu virus results in the infection of more people in the world as compared to HIV patients so we can conclude that flu virus is more common than HIV virus due to its activeness.

In a site that contains multiple domain controllers, how long will a domain controller wait after notifying its first replication partner before sending the change notification to its next replication partner?
Answer:
3 seconds
Explanation:
3 seconds
In this kind of a situation where there exists multiple replica domain controllers that are present in the site, then the source domain controller being the one, will have to wait three seconds after issuing the first change notification. Thereafter, it then sends a change notification to the next domain controller.
In a histology lab a scientist observes the following features under the microscope. Which of these
observations supports cell theory?
I. Cardiac cells are joined by gap junctions and contain three nuclei.
II. Mature platelet cells do not contain a nucleus, but do contain mitochondria.
III. Spermatogonia undergoing mitosis.
IV. The bulk of tissue samples from endocrine glands contain cells as their main building blocks.
option III and IV supports cell theory.
The three essential concepts of cell theory are that: 1. cells are the fundamental building block of life; 2. living creatures consist of one or more cells; and 3. cells originate from preexisting cells.
Hint #2 2 / 4
In cell theory, the quantity of nuclei is not taken into account.
Hint #3 3 / 4
A new cell is produced during the process of cell division known as mitosis. This idea—that cells form from already-existing cells—is exact.
Hint #4 4 / 4
III and IV are both illustrations of cell theory in the actual world. Mitosis, which is the process by which preexisting cells divide to form new ones, demonstrates how cells make up living things, as does the cellular makeup of glands.
