tissue respiration, location in the cell and sequence of reaction
Answer:
The Location of Cellular Respiration
Cellular respiration takes place in both the cytosol and mitochondria of cells. Glycolysis takes place in the cytosol, whereas pyruvate oxidation, the Krebs cycle, and oxidative phosphorylation occur in the mitochondrion.
Tissue respiration occurs internally where the oxygen carried by the blood and RBCs is exchanged with the carbon dioxide produced by the cells of various tissues. ( This answers the location of where tissue respiration occurs
Sequence of tissue respirationThe stages of tissue respiration include:glycolysis - pyruvate oxidation - citric acid or Krebs cycle - oxidative phosphorylation.
Cell tissue respiration
It is the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water
Cellular tissue respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical energy from oxygen molecules or nutrients into adenosine triphosphate, and then release waste products.

What is one of the results of an increase in the amount of greenhouse gases in the atmosphere?
А
increased overall ocean salinity
B
decreased global polar ice melting
с
increased overall atmospheric humidity
D
decreased global surface temperatures
Answer:
C) Increased overall atmospheric humidityIncreasing overall atmospheric humidity is the result of an increase in the amount of greenhouse gases in the atmosphere. Therefore, option C is correct.
What are greenhouse gases?The gases that trap heat in the earth's atmosphere are referred to as greenhouse gases. The earth's surface warms during the day when the light beams through the atmosphere. The earth's surface cools at night, redistributing heat into the atmosphere. However, part of the heat is captured by the atmosphere's greenhouse gases.
Due to minute concentrations of water vapor (H2O), carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) in the atmosphere, the Earth has a natural greenhouse effect.
Increasing overall atmospheric humidity is the result of an increase in the amount of greenhouse gases in the atmosphere. Therefore, option C is correct.

Granite is an intrusive igneous rock with large crystals because it cools slowly. this rock most likely formed on the surface of a volcano. thus option D is correct.
What is rock cycle ?
Rocks are naturally occurred on non-living earth which are made by collection of mineral grains held together in a firm, it can be tiny or big as well and can be easily identified with their texture.
The Rock cycle can be defined as a continuous process through which old rocks are transformed into new rock due to cool down of molten magma, when it solidifies become igneous rock.
In a rock cycle, when the break down of these igneous rocks occur small particles that are transported and deposited to form sedimentary rocks, When the igneous and sedimentary rocks heated up and under the pressure they change into metamorphic rocks.
The metamorphic rocks which are subjected under great heat and pressure melt down to form molten magma which again can cool down and solidify into igneous rocks

if the dna sequence is TAC CCC AAG CTC GGT ATC. what is mRNA
tRNA
AA?
The mRNA sequence would be:
AUG GGG UUC GAG CCA UAG
The mRNA sequence is complementary to the DNA sequence, in other words would just basically mean you do the opposite of the bases to the DNA sequence such that:
Cytosine with Guanine
Thymine (uracil for RNA) with Adenine
However, mRNA has Uracil instead of Thymine, so instead the uracil in mRNA binds with adenine.
Urcacil with Adenine
For tRNA, they have anticodons, meaning they have bases complementary to the mRNA strand, so the tRNA with the complementary anticodon sequence would be:
UAC CCC AAG CUC GGU AUC (DNA sequence but replace thymine with uracil)
For the amino acids, they would bond to the specific tRNA molecules with the specific bases on the anticodons.

Explanation:
Is cloning of endangered species a reliable and acceptable way to repopulate those ecosystems that suffer the loss of important species? Why or why not. (2 paragraph
minimum).
Cloning an extinct species is a possible answer for a suffering ecosystem. The only drawback is that scientists have not yet mastered cloning. When attempting to clone animals often they are deformed and therefore not able to reproduce let alone survive. Even when scientists do manage to clone animals without killing them, it takes many generations of selective breeding to get the species you are trying to revive which takes time, making the ecosystem even more damaged.
The study of a living being is called biology.
The correct answer is not reliable.
The duplication of the genes in the laboratory is called cloning.
The first clone species was the sheep whose name was a dolly.
Those species which are on the verge of extinction is called endangered species and they need extra protection to carry their gene to the next generation.
The cloning will be able to multiply the gene in the in-vitro culture but they will have a direct impact on the natural genes and the combination of the gene present in nature.
The natural species have all the desired genes which help them to survive in nature, whereas the clone species will not have the desired gene which is required to adapt to nature and they will extinct eventually. If these genes pass on to the next generation then the endangered species will also have less chance to survive in nature.
Hence, in my opinion, they cloning is not a suitable way to save endangered species.

Regarding cell walls, which of
these is the MOST accurate?
im
A. Cell walls and cell membranes are the very
same thing
B. Cell walls burst any time the cell takes in too
much water.
C. Cell walls keep a plant, bacteria or fungus cell
from bursting when too much water is absorbed
Answer:
C
Explanation:
cell wall
When water moves into a plant cell, the vacuole gets bigger, pushing the cell membrane against the cell wall. The force of this increases the turgor pressure within the cell making it firm or turgid . The pressure created by the cell wall stops too much water entering and prevents cell lysis.
Which of the following is an example of gene flow?
O The movement of people on Earth steadily increases and alters the course of human evolution
An earthquake results in the formation of a canyon, splitting a population of toads apart
O A fire drastically reduces the size of a white-tailed deer population. The remaining individuals spread out throughout the remaining forest
A small population of grasshoppers gets blown away and isolated during a storm. The gene pool of the new population is different from the original population
An example of gene flow is: A. The migration/movement of people on Earth which gradually increases and alters the course of human evolution.
What is Gene Flow?Gene flow, which can also be referred to as gene migration, is the transfer of genes or genetic material from one population of a species to another.
Migration of humans from one region to another leads to people of one race intermarrying with people of another entire race.
For example, A European migrating to North America, and getting married to a North American thereby giving birth to offspring exhibiting traits of booth a European and a North American. A gene flow has occurred.Therefore, an example of gene flow is: A. The migration/movement of people on Earth which gradually increases and alters the course of human evolution.

List the angles in order from smallest to largest. Note image in not drawn to scale
Using sine rule and cosine rule, the angles from smallest to largest is A,B,C.
Using the cosine rule;
a^2 = b^2 + c^2 - 2bc cos A
When;
a = 9 cm
b = 16 cm
c = 18 cm
9^2 = 16^2 + 18^2 - (2 × 16 × 18) cos A
81 = 256 + 324 - (576) cos A
81 = 580 - 576 cos A
81 - 580 = - 576 cos A
cos A = (81 - 580)/ - 576
A = cos-1[(81 - 580)/ - 576]
A = 30°
Using the sine rule;
a/sin A = b/sinB
asinB = bsinA
sinB = bsinA/a
B = sin-1(bsinA/a)
B = sin-1[(16 × sin30)/9]
B = 63°
Now;
A + B + C = 180(Sum of angles in a triangle)
C = 180 - ( A + B)
C = 180 - ( 30 + 63)
C = 87°
The angles are A, B, C.
