Introduction

Does cell cycle control matter? If you ask an oncologist – a doctor who treats cancer patients – she or he will likely answer with a resounding yes.

Cancer is basically a disease of uncontrolled cell division. Its development and progression are usually linked to a series of changes in the activity of cell cycle regulators. For example, inhibitors of the cell cycle keep cells from dividing when conditions aren’t right, so too little activity of these inhibitors can promote cancer. Similarly, positive regulators of cell division can lead to cancer if they are too active. In most cases, these changes in activity are due to mutations in the genes that encode cell cycle regulator proteins.

Here, we’ll look in more detail at what's wrong with cancer cells. We'll also see how abnormal forms of cell cycle regulators can contribute to cancer.

What’s wrong with cancer cells?

Cancer cells behave differently than normal cells in the body. Many of these differences are related to cell division behavior.

For example, cancer cells can multiply in culture (outside of the body in a dish) without any growth factors, or growth-stimulating protein signals, being added. This is different from normal cells, which need growth factors to grow in culture.

Cancer cells may make their own growth factors, have growth factor pathways that are stuck in the "on" position, or, in the context of the body, even trick neighboring cells into producing growth factors to sustain them^1

Diagram showing different responses of normal and cancer cells to growth factor presence or absence.

Normal cells in a culture dish will not divide without the addition of growth factors.

Cancer cells in a culture dish will divide whether growth factors are provided or not.

Cancer cells also ignore signals that should cause them to stop dividing. For instance, when normal cells grown in a dish are crowded by neighbors on all sides, they will no longer divide. Cancer cells, in contrast, keep dividing and pile on top of each other in lumpy layers.

The environment in a dish is different from the environment in the human body, but scientists think that the loss of contact inhibition in plate-grown cancer cells reflects the loss of a mechanism that normally maintains tissue balance in the body^2

squared.

Another hallmark of cancer cells is their "replicative immortality," a fancy term for the fact that they can divide many more times than a normal cell of the body. In general, human cells can go through only about 40-60 rounds of division before they lose the capacity to divide, "grow old," and eventually die^3

cubed.

Cancer cells can divide many more times than this, largely because they express an enzyme called telomerase, which reverses the wearing down of chromosome ends that normally happens during each cell division^4

Cancer cells are also different from normal cells in other ways that aren’t directly cell cycle-related. These differences help them grow, divide, and form tumors. For instance, cancer cells gain the ability to migrate to other parts of the body, a process called metastasis, and to promote growth of new blood vessels, a process called angiogenesis (which gives tumor cells a source of oxygen and nutrients). Cancer cells also fail to undergo programmed cell death, or apoptosis, under conditions when normal cells would (e.g., due to DNA damage). In addition, emerging research shows that cancer cells may undergo metabolic changes that support increased cell growth and division^5

Answer:

Antibiotics save lives but any time antibiotics are used, they can cause side effects and lead to antibiotic resistance.

Since the 1940s, antibiotics have greatly reduced illness and death from infectious diseases. However, as we use the drugs, germs develop defense strategies against them. This makes the drugs less effective.

Answer:

DNA mutations or Chromosomal mutations are also called chromosomal aberrations, chromosomal abnormality, or chromosomal disorders, all indicating a possible alteration in the morphology and structure of the chromosome.

DNA mutations lead to abnormalities in the function of the cell and organism, as chromosomal or DNA mutations can result in abnormal gene numbers or positions.

These are known to cause different genetic diseases that can be hereditary and are transferred from one generation to another.

These mutations, however, do not always affect the functioning of the cell as some mutations might affect regions of chromosomes that do not make up the genetic makeup of the organism.

Even though gene mutations are usually more severe than chromosomal mutations, some chromosomal mutations might result in gene mutations.

11. There are two main stages of photosynthesis: the light-dependent reactions and the Calvin cycle.

12. Nutrition is necessary for the growth of new cells and the replacement or repair of worn-out cells. Nutrition gives energy for different metabolic processes in the body. Nutrition is required to produce resistance against different diseases.

13. trypsin

14. salivary amylase

15. Hydrochloric acid helps your body to break down, digest, and absorb nutrients such as protein. The hydrochloric acid found in the stomach facilitates digestion by disintegrating complex large food molecules into simpler molecules. The acid activates the pepsinogen enzyme required to digest proteins.

16. Saliva, the watery liquid produced by glands located under the tongue, is an essential component of the digestive process. Saliva is 98% water, so it moistens the mouth and helps compact food into softened particles for easier swallowing.

17. Digestive enzymes play a key role in breaking down the food you eat. These proteins speed up chemical reactions that turn nutrients into substances that your digestive tract can absorb. Your saliva has digestive enzymes in it. Some of your organs, including your pancreas, gallbladder, and liver, also release them.

Answer:

Both depends on one another.

Explanation:

Yes, there is a direct relationship between the number of pollinating plants and the number of honeybees because honeybees are insects that are responsible for pollination in the flowering plants. The population of flowering plants also has a great effect on the survival of honeybees because these flowering plants provides food in the form of nectar on which these honeybees survive and make honey from it. So we can say that both flowering plants and honeybees depends on one another for the successful growth and development.

Explanation:

Lipids are macromolecules composed of fatty acids. The diagram represents the inability of the lipids to break in the water. Thus, option c is correct.

Lipids are said to be polymers as they are large molecules made of the monomers of the fatty acid chains and glycerol bonded together by chemical bonds. They include oils, fats, steroids, waxes, hormones, phospholipids, etc.

They are energy storage molecules along with carbohydrates and act as messengers in the form of hormones. They store energy in fat cells (adipose) for a longer period of time. They make the component of the cell membrane, blood cells, and cholesterol.

They are soluble in an organic solvent but not in water as it is a non-polar compounds with hydrophobicity and hydrophilicity. They are insoluble and remain intact in the water molecule.

Therefore, option c. the lipids do not break in the water.

Answer:

It has four main components: plasma, red blood cells, white blood cells, and platelets. Blood has many different functions, including transporting oxygen and nutrients to the lungs and tissues

Explanation:

Plasma is the main component of blood and consists mostly of water, with proteins, ions, nutrients, and wastes mixed in. Red blood cells are responsible for carrying oxygen and carbon dioxide. Platelets are responsible for blood clotting. White blood cells are part of the immune system and function in immune response.

From studies and research, I believe the proper question would be:

"How do the animals satisfy their need for water?" or "How long do the animals live?"

Explanation 1:

When studying the desert, asking "Can you buy the animals in pet stores?" is not going to help you find information about the desert because it is not a question to get information about the desert, only information if you just buy it at your local pet shop.

Explanation 2:

Asking "How many offspring do the animals have?" does help us learn about animals, but we are trying to find information on the structure of the desert in which the animals live in. We are not looking for how many children the animals will have because it doesn't fully relate to the question we would be asking.

Side Note: Offsprings mean children.

Answer:

Regulation / Homeostasis  you get too hot or too cold:

  If you get either too hot or too cold, sensors in the periphery and the brain tell the temperature regulation center of your brain—in a region called the hypothalamus—that your temperature has strayed from its set point.

Your diaphragm expands and contracts so you can breathe:

  When you breathe in, or inhale, your diaphragm contracts and moves downward. This increases the space in your chest cavity, and your lungs expand into it. The muscles between your ribs also help enlarge the chest cavity. They contract to pull your rib cage both upward and outward when you inhale.

Nutrient Absorption

The reactants needed for cellular respiration are taken in and transported to your cells:

cellular respiration requires oxygen and releases carbon dioxide. It is the released oxygen that is used by us and most other organisms for cellular respiration. We breathe in that oxygen, which is carried through our blood to all our cells.

Defense from Illness

A pathogen enters your body through a cut:

The skin and mucous membranes act as a physical barrier preventing penetration by microbes. If the skin is cut then the blood produces a clot which seals the wound and prevents microbes from entering.

Defense from Injury

A bunny is running away from a wolf:

Rabbits have keen senses of smell, sight and hearing, which help them defend themselves from danger. When they sense a nearby predator, they innately freeze in place to camouflage with the landscape.

Your hand gets too close to a flame:

Skin is difficult to ignite, and usually chars in the presence of heat. It takes up to 10 minutes of direct flame for skin to crack open and start leaking out rendered fat. Even if a horse's body started to leak fat, it would be unlikely to go up in flames on its own.

Reproduction

A woman’s body prepares for a pregnancy:

Every month, usually one egg grows within a structure called the egg follicle (a fluid filled sac that nourishes the egg). The follicle produces estrogen, which helps a woman's body prepare for pregnancy by growing a new lining for the uterus.

A woman’s body prepares for a birth:

As your body prepares for birth, your cervix — the muscular ring between your uterus and vagina — begins to soften, dislodging the mucous plug.

Answer:RNA code for Amino Acids that make Proteins through the process of translation

Explanation:

During translation, tRNA recognizes the mRNA codons, complements them, and add the correct amino acid to the growing protein. CODON and PROTEIN are the missing words.

--------------------------------------------------------------------------

Protein synthesis

Occurs in two steps. Transcription and translation.  

Transcription ⇒ mRNA syntheis

Translation:

⇒ Cytoplasm stage

• Translation takes place when the formed mRNA moves to the cytoplasm through the nucleus membrane pores.  

• Once in the cytoplasm, mRNA meets a ribosome, which is the primary structure for protein synthesis.

• Ribosomes are organelles composed by the association of proteins with rRNA and tRNA. They can be found in the rough endoplasmic reticulum or floating in the cytosol.  

• While the ribosome reads mRNA strain from its 5´ extreme to 3´, tRNA adds the correct amino acids to build the polypeptide.  

                     →    mRNA is composed of different codons.  

                     →    Each codon is a chort sequence of  

                    three nucleotides that codes for one amino acid.  

                     →    When tRNA molecules recognize these                                                                                                  

                            sequencies, they add the correct amino  

                                   acid to the growing protein.  

⇒ Protein synthesis ends when the proteins passes through the Endoplasmic Reticulum and the Golgi complex for their final folding process.

Answer:

2. C - Red pandas in this population have encountered new environmental challenges presented by the increase in deforested land, and this has selected for different adaptations over time.

5. D - A desert that has existed for millennia.

Explanation:

2. Predation (A) and fertility (B) are easy scratch-off answers -- given the situation of deforestation, these factors will not influence genetic diversity. Although eating patterns can lead to new adaptations, the best answer is C because it results directly from the issue at hand: deforestation.

5. To limit the amount of population diversity, you would have to maintain the same environment as much as possible. In other words, migration and isolation lead to the creation of new species per Darwin's theory of Natural Selection. For that reason, the only plausible answer here is D.
