11. Diabetics are often required to monitor their blood glucose levels to determine
if/when they require a shot of insulin. Under what conditions should diabetic
individuals give themselves a shot of insulin?
Answer: When blood glucose levels rise beyond the normal level (hyperglycaemia), an insulin injection is needed.
Explanation: This applies to insulin-dependent diabetes, i.e. Type I, where the medical diagnosis is insulin insufficiency. The situation with Type II diabetes is less straightforward.
Insulin is required to enable glucose to be distributed as required, taken up by cells as they need it. Glucose is constantly produced. Without insulin, little glucose is removed from the blood, and the blood glucose concentration rises. The symptoms of this hyperglycaemia include unusual thirst, frequent urination and tiredness. Unless very high levels are reached this may not be severe enough to be noticed, which is why diabetics monitor their blood glucose levels - to avoid those severe episodes. If their blood glucose exceeds normal levels, an insulin injection is needed

When environmental change occurs, variation allows for individuals with characteristics that are most beneficial to survive and reproduce at higher rates than those that are less well-adapted.
a. True
b. False
Answer:
a. True
Explanation:
According to the evolutionary theory proposed by Darwin, adaptation is the process by which organisms adjust to new environments in order to survive and reproduce. An organism that is better able to adjust to the changing environment will have more chances to survive and reproduce in order to pass its genes to the next generation. The differential survival and reproduction of organisms in a population caused by differences in the phenotype is known as "natural selection", which is the most common mechanism of evolution.
Answer:
False
Explanation:
Traits that are not heritable will be lost with time, heritability of a traits lead to its continuity.
Heritability is the proportion of variation that is heritable.
If a traits is not inherited or passed to the successive generation the ability of such traits to continue is low and with time such traits is loss.
An organism may reproduce well, have characteristics that are important it does not lead to survival heritable traits controlled by major genes is what leads to survival of traits and its availability.

Meiosis
During the cell cycle, the cell divides its nucleus and chromosomes during 1._____. The cytoplasm and cell membrane divide during 2_____. Before the cell can divide again, it must grow and synthesize proteins during the 3._____ phase and duplicate its chromosomes during the 4._____ phase.
A. cytokinesis
B. G1
C. mitosis
D. S
Answer:
c: mitosis
Explanation:
In mitosis, the nuclear DNA of the cell condenses into visible chromosomes and is pulled apart by the mitotic spindle, a specialized structure made out of microtubules. Mitosis takes place in four stages: prophase (sometimes divided into early prophase and prometaphase), metaphase, anaphase, and telophase.

One cell phone contains many metals, including about 25 g
of aluminum, about 15 g of copper, about 0.03 g of gold,
and about 0.3 g of silver.
Based on this information, which resource is most likely used to make cell
phones?
A. A large river and its streams
B. An old-growth forest of tall trees
C. A farm with sheep and cattle
D. An underground deposit of minerals
The correct answer is D. An underground deposit of minerals.
Explanation
Metals are minerals, that is, they are natural substances that are normally in a solid-state. These resources are generally the product of physical-chemical processes that occur in the underground layers of the earth that transform different materials into these minerals. These minerals are obtained through mining, a process in which the earth's crust is broken until it reaches the place where these minerals are housed and in this way takes them to the surface to use them in the manufacture of different objects. Therefore, the correct answer is D. An underground deposit of minerals.
What type of cells do antibiotics work on?
Answer: Prokaryotic cells
Explanation:
The reason antibiotics are so effective is because they have properties that selectively attack bacteria cells while leaving human cells unscathed.
Bacteria cells are prokaryotic which means that they have cells walls. Human cells on the other hand are Eukaryotic which do not usually have cell walls.
Antibiotics majorly work by attacking the cell walls of bacteria thus making it weak and prone to bursting or easier to destroy by the body's immune system while leaving human cells which do not have the cell walls.
Other antibiotics work in different ways but generally do so by attacking prokaryotic characteristics.

which of external structure directly impacts the effectiveness of the host immune system
Answer: Capsule
Explanation:
The external structure that directly impacts the effectiveness of the host immune system is the capsule.
The capsule is known to be bad for the immune system of the host as it enhances the bacteria's ability to cause disease to the host organism. This they do through the prevention of phagocytosis. With the help of the capsule, th defense of the host organism can therefore be evaded easily.
Which two statements about forces are true?
A. Every force has an equal but opposite force.
B. Every force requires matter to touch.
C. Forces are always balanced.
D. Forces organize and affect how matter moves.
Answer: A. Every force has an equal but opposite force.
D. Forces organize and affect how matter moves
Explanation:
For every interaction, we should note that we have forces that act on the two objects that are involved. Also, Forces organize and affect how matter moves.
The idea that every force requires matter to touch is wrong. There are some non-contact forces that doesn't need physical touch e.g friction, pull. Also, there are balanced as well as unbalanced forces.
Therefore, the correct options are A and D.

Read the section "Brains Under Construction."
Select the paragraph from the article that suggests
specific regions of the brain can perform multiple
functions.
A. Let's break that down, starting with preteen
and teen behaviors. The brain region that tells
us we shouldn't eat chips all the time and
helps us resist that urge is the last to
mature. Called the prefrontal cortex, this
region doesn't fully develop until we are in our
early 20s.
B. "Most of our complex brain functions happen
in the prefrontal cortex, says Reichelt. This
includes complex math and reading, but she
notes that it also includes "how to assess risky
behavior."
C. In fact, these regions are even more sensitive
when we are young. That's because of a
natural chemical called dopamine. Dopamine
is sometimes called the "feel good chemical,
and it lifts our mood when we experience
something rewarding. And it is especially
active in adolescent brains.
D. The teen brain, thus, has two strikes against it
when it comes to resisting junk food. 'It has a
heightened drive for rewards and reduced self-
regulation," says Reichelt.

Draw an X on the template in the space provided for your response to indicate the phase during which the replication of damaged DNA would occur.
Answer and Explanation:
Replicating DNA is delicate and can breakdown in the process of duplication. The source of DNA rearrangements is broken chromosomes. These chromosomes can alter the cell genetic program. These modifications can activate a growth advantage in a single cell in our body—tumor rise when that cell remains to divide. Cells have defense mechanisms to protect us from these harmful actions. In the eukaryotic cell cycle, chromosomes segregate during the M phase and duplicate during the S phase. The S phase is known as the phase of DNA synthesis, while the M phase is known as the mitosis phase. Any problem with DNA replication activates a checkpoint during the S phase. A checkpoint is a flow of signaling events that places the phase on hold till the issue is resolved—the checkpoint of the S phase work as a surveillance camera. The main purpose of the replication is to produce an identical double strand. Each strand in a DNA molecule functions as a template for a new DNA strand.

An individual running a marathon may experience periods of oxygen deprivation that can lead to
A. anaerobic respiration in muscle cells, forming lactic acid
B. acrobic respiration in muscle cells, generating glycogen
C. anaerobic respiration in liver cells, producing glucose
D. aerobic respiration in liver cells, synthesizing alcohol
Answer:
A. anaerobic respiration in muscle cells, forming lactic acid
Explanation:
Running marathon is a vigorous exercise, which often leads to excessive use of oxygen in the cells of the athlete. This causes the cells to switch from the aerobic (with oxygen) to the anaerobic (without oxygen) mode of respiration. This anaerobic respiration produces a product called LACTATE OR LACTIC ACID.
The lactic acid becomes excessive and gets stored in the muscle cells of the athlete. This often leads to cramps, muscle pulls etc. during the marathon. Therefore, an individual running a marathon may experience periods of oxygen deprivation that can lead to anaerobic respiration in muscle cells, forming lactic acid.
