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
Answers
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.
The correct words to fill the gaps in the cell cycle illustration are:
mitosiscytokinesisG1SDuring the cell cycle, the cell divides its nucleus and chromosomes during mitosis. The cytoplasm and cell membrane divide during cytokinesis. Before the cell can divide again, it must grow and synthesize proteins during the G1 phase and duplicate its chromosomes during the S phase.

which of external structure directly impacts the effectiveness of the host immune system
Answers
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.

Chemical analysis of mitochondria indicates that these organelles are found within cell nuclei ос do not contain enzymes transport hemoglobin contain ATP molecules
Answers
Answer:
The correct answer is ''contain ATP molecules.''
Explanation:
Energy is produced through a series of chemical reactions coupled to a chain of transport of electrons to oxygen, transforming the energy that is generated into ATP these reactions are carried out thanks to the joint action of a series of proteins and other substances that transport electrons that are located in the inner membrane of the mitochondria and that constitute the oxidative phosphorylation system. The functions of the mitochondria were limited to some metabolic pathways, such as the respiratory chain - that is, the series of biochemical reactions that release the necessary energy to synthesize adenosine triphosphate, or ATP–, oxidative phosphorylation –the synthesis of the ATP molecule– and thermogenesis, which is the extra generation of heat in adipose tissue called 'brown'. The ATP molecule, due to its chemical structure, constitutes the main energy reserve available to the cell to carry out its functions.
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.
Answers
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.

What type of cells do antibiotics work on?
Answers
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.

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
Answers
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.

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.
Answers
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.

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?
Answers
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

A scientist injected some cells with a drug that blocked glycolysis after NADH was formed, but before ATP and pyruvate were formed. All the other enzymes used in cellular metabolism were unaffected. How would the production of ATP in the cell be affected?
Answers
Answer:
The cell could not make ATP.
Explanation:
Glycolysis may be defined as the process in which a glucose molecule is broken down into the two molecules of the pyruvate. Pyruvate is used to produce energy through various pathways that depends upon the availability of the oxygen. However when the glycolysis in blocked and the pyruvate is not formed, then the cells would not be able to use either the fermentation or aerobic respiration or the perform citric acid cycle. So the cell does not make any ATP.
