In a DNA molecule, the complementary strand is the one composed of bases that pair -complement- the bases of the original strand. The complementary strand is TACCCGATCAGAA.
What is a complementary strand?During DNA replication, the molecule unwinds and the two strands are separated. These are the original strands.
Once the strands are separated, the elongation process begins, in which new nucleotides are added to complement each of the original strands.
A DNA molecule grows composed of an old existing strand, which is used to synthesize the new complementary strand.
After DNI replication each new molecule carries an original DNI strand and a new one.
So, the complementary strand is the new one composed of bases that pair the bases from the original strand.
In DNA molecules, Adenine pairs Thymine, and Cytosine pairs Guanine.
In the exposed example,
Original strand ⇒ ATGGGCTAGTCTT
Complementary strand ⇒ TACCCGATCAGAA

Mr. Devereaux's students were in science lab trying to identify biomolecules: carbohydrates, fats and proteins. During the lab experience, Assistant Principal Haskins came in to evaluate the teacher and the learning environment. Ms. Haskins reacted positively to the fact that the students were conducting a hands-in investigation, but she reacted negatively to the overall classroom environment. Take a look at one lab group. Justify Ms. Haskins' concern. What procedures should Mr. Devereaux have followed before the lab began?
Your teacher will probably go over the lab procedures with you and your classmates before you lead an experiment.
You will often receive a printed guide that describes the experiment in depth in addition to verbal instructions, frequently with pictures and drawings.
It's important to pay attention as your teacher goes over the directions so you can complete the experiment correctly and securely when class starts.
What precaution should we take while experimenting in lab?Be careful when handling chemicals, reagents, and stains, and heed all instructions. The contents and any potential hazards are listed on the labels of all bottles and containers. Avoid contact with the chemical and fumes, for instance, if the label instructs you to.
Your teacher will probably go over the lab procedures with you and your classmates before you lead an experiment.
You can keep yourself safe in the lab with the appropriate clothing and tools. Depending on the experiment, your teacher should provide you with particular directions on what to wear to each class as each one calls for the use of various tools and substances that have varying degrees of hazard.
Though they are not something you should be preoccupied by, as mentioned above, accidents in school laboratories are rather common. Your teacher should review with you what safety equipment your lab contains.

A microscope has a low-power magnification of 200x and a high-power magnification of 1600x. If the low-power field diameter is 1.2 mm, calculate the high power field diameter in micrometers
The diameter of the high power field in micrometers is 9600 micrometer (9.6 mm).
[tex]\frac{200}{1600} =\frac{1,2}{x}[/tex] = 9,6 mm
What are microscope lenses?Compound microscope lenses are called objective lens and ocular lens. The objective lens is a lens that is installed very close to the object being observed. The ocular lens is very close to the observer's eye.
With this information, we can conclude that the high power field in micrometers is 9600 micrometer (9.6 mm).

A hairdryer uses 1500 J of electrical energy in 1 second. The hairdryer changes 1300 J of this to useful thermal energy in 1 second. Calculate the quantity of energy that is wasted by the hairdryer in 1 second. Show your work.
200 J of energy is wasted by the hair dryer.
Steps
The hairdryer is provided with 1500 J of electrical energy per secondOf this 1500 J, 1300 J of energy is actually used and converted to useful thermal energy per secondThe remaining energy, 1500 - 1300 = 200 J is dissipatedDissipated energy
The energy that is not efficiently transported or changed is wasted energy. We cannot create or destroy energy. An employable type of energy is created through transformation. Only a portion of energy that is changed or transferred can be done so in a way that is helpful.Thus, 200 J of energy is wasted by the hair dryer.

How do acacia trees communicate with each other in response to insect attack?
O They produce a gas called ethylene.
O They drop their leaves.
O They release pollen.
O They produce thorns and spines
Acacias communicate with each other in response to insect attack by producing a gas called ethylene.
How do acacias communicate?When antelopes begin to eat the leaves of an acacia tree, the tree emits a signal of ethylene gas into the air through the pores of its leaves. This signal can travel up to 45 meters warning other nearby trees of the presence of herbivores. Once the signal is received, acacias begin to produce tannin in their leaves in amounts that are lethal to antelopes.
With this information, we can conclude that Acacia trees, when eaten by grazing giraffes, release ethylene gas, which prompts other acacias to flood their leaves with bitter tannins.

The correct option for the image showing carbon dioxide moving is the biosphere to the atmosphere. Therefore, the correct option is C.
Respiration and combustion are the main processes by which carbon dioxide [tex]\rm (CO_2)[/tex] is transferred from the biosphere to the atmosphere. In the biosphere, which is made up of all living things and organic matter on Earth, plants and animals release carbon dioxide as a result of consuming oxygen [tex]\rm (O_2)[/tex].
Additionally, human activities such as the combustion of fossil fuels for energy also contribute significantly to atmospheric emissions of carbon dioxide. This human-caused process is a major contributor to the increase in atmospheric carbon dioxide levels, which is a major contributor to climate change.

The correct answer is (A). Deforestation.
What do you mean by deforestation?Deforestation or forest clearance is the removal of a forest or stand of trees from land that is then converted to non-forest use. Deforestation can involve conversion of forest land to farms, ranches, or urban use. The most concentrated deforestation occurs in tropical rainforests.
Moreover, deforestation is the purposeful clearing of forested land. Throughout history and into modern times, forests have been razed to make space for agriculture and animal grazing, and to obtain wood for fuel, manufacturing, and construction. Deforestation has greatly altered landscapes around the world.
Hence, the loss of trees and other vegetation can cause climate change, desertification, soil erosion, fewer crops, flooding, increased greenhouse gases in the atmosphere, and a host of problems for Indigenous people.
