and I think "Cancer does not obey contact inhibition." is one too... I hope this helps! :D

Explanation:

Cancer cells:

• Divide uncontrollably

• Comes in many forms

Invade healthy tissues

• Does not obey contact inhibition

What is cancer?

Cancer is a diseased condition in which uncontrolled cell division takes place.

Cancer are of two main types: benign and malignant.

Benign tumours are localized to a particular organ and thus can be removed through chemotherapy or surgery.

Malignant tumours spread to body parts through blood stream and attack the healthy cells. This property of metastasis is unique to cancer cells.

Normal cells show their contact with the adjacent cells. In cancer, contact inhibition is lost and so they divide in an uncontrolled manner.

Breast cancer, leukaemia, lung cancer etc are some of the examples of cancer.

Cancer is detected through tissue biopsy. X-Rays, CT-Scan, MRI are some other techniques that detect cancer in the body.

Cancer can be treated if diagnosed early. Radiotherapy, chemotherapy and surgical intervention are the part of cancer treatment.

Therefore, cancer is considered a serious medical complication.

New Zealand has a population of 4,326,380 and has an area of 103,736 miles squared while Australia has an area of 2,967,909 miles squared and a population of 21,905,140. Explain how New Zealand can have a larger population density than Australia even though it has a smaller total population.

Answers

The reason they have a higher population density is because they have more people on average in a certain area, because New Zealand is smaller they are given less space to live, this means that more people are crammed together, making the density of people within a square mile higher. When you give less square miles, you reduce the amount you have to divide the population by, which makes the density go up.

( In case you wanted the calculations for the density on New Zealand and Australia, it is about 41 to 42 people a square mile in Zealand, and maybe 7 or 8 per square mile in Australia.)

Answers

Answer:

1. In the process of photosynthesis, plants convert the energy of sunlight into chemical energy stored in the bonds of carbohydrates.

a. The light-dependent reactions use light energy to make two molecules needed for the next stage of photosynthesis: the energy storage molecule ATP and the reduced electron carrier NADPH. In plants, the light reactions take place in the thylakoid membranes of organelles called chloroplasts.

b. In the Calvin cycle (light independent reactions), carbon atoms from CO2 are fixed (incorporated into organic molecules) and used to build three-carbon sugars. This process is fueled by, and dependent on, ATP and NADPH from the light reactions. Unlike the light reactions, which take place in the thylakoid membrane, the reactions of the Calvin cycle take place in the stroma (the inner space of chloroplasts).

2. When transitioning to respiration, photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.

3. Cellular respiration is the aerobic process by which living cells break down glucose molecules, release energy, and form molecules of ATP. Overall, this three-stage process involves glucose and oxygen reacting to form carbon dioxide and water.

a. Fermentation refers to the metabolic process by which organic molecules (normally glucose) are converted into acids, gases, or alcohol in the absence of oxygen or any electron transport chain.

4. They are similar because they both produce energy but in two different forms.

Photosynthesis- It produces oxygen and G3P, simple carbohydrate molecules that are high in energy and can be converted into glucose, sucrose, or other sugar molecules.

cellular respiration-During cellular respiration, a glucose molecule is gradually broken down into carbon dioxide and water.

Explanation:

1. A process in which the plants prepares their food from inorganic compounds and light energy is called photosynthesis.

The energy stored in the carbohydrates is used in the preparation of chemical energy.

a. In reactions that use light for the process is called light-dependent reactions. It transpires in the thylakoid organelle of the chloroplast. The light is needed for the synthesis of ATP and NADPH which is a reduced electron carrier.

b. The reactions in which the carbon dioxide is fixed from the carbon source to produce three-carbon sugars is called light-independent reactions. The process of the Calvin cycle transpires in the stroma of the chloroplast.

2. When transpiration changes to the respiratory pathway then glucose is produced during photosynthesis and is used in the process of cellular respiration to produce ATP.

The produced glucose gets converted back into carbon dioxide through the process of expiration.

The water molecules get broken into oxygen during photosynthesis and in another process of cellular respiration, the oxygen combines with hydrogen to yield water.

3. The aerobic process that requires oxygen molecules to break glucose molecules in living organisms to produce ATP and releases energy is called cellular respiration.

The process comprises a reaction between glucose and oxygen to produce carbon dioxide and water.

a. The metabolic process in which the organic molecules are converted to gases, alcohol and acids in the absence of ETC or oxygen is called fermentation.

4. The process of photosynthesis and cellular respiration have similar molecules as:

In the photosynthesis process molecules produced are oxygen, carbohydrates that are high in energy and get converted to glucose or other sugar molecules. In cellular respiration, glucose gets broken into water and carbon dioxide.

Answers

Answer:

I think the cytoplasm keeps the cell solid.

Explanation:

Cytoplasm keeps all the cellular organelles suspended. The cytoplasm helps to keep them in place. It is also the site of most metabolic activities in the cell, and it allows materials to pass easily throughout the cell.

The cytoplasm is the liquid that keeps the cell solid. The correct option is C.

What is cytoplasm?

The cytoplasm is a liquid that is filled inside the cell. Between the cell membrane and the nucleus, there is a jelly-like fluid called cytoplasm. It facilitates material exchange and storage among cell organelles.

Cytoplasm helps the cell to stay still and rigid. It places all the cell organelle into a fixed place and the transfer of ions and molecules is also done by the cytoplasm. It is made up of water, salts, and other various material.

They help in the coming in of the materials and going out of the materials. They also protect the cell from shock and other invasive, they make the cell rigid and flexible and also protect recall from each other.

Thus, the correct option is C. solid.

An agricultural biologist was evaluating two newly developed varieties of wheat as potential crops. In an experiment, seedlings were germinated on moist paper towels at 20ºC for 48 hours. Oxygen consumption of the two-day-old seedlings was measured at different temperatures. The data are shown in the graph below. In a second experiment, variety A seedlings at both temperatures were treated with a chemical that prevents NADH from being oxidized to NAD+. Predict the most likely effect of the chemical on metabolism and oxygen consumption of the treated seedlings. Explain your prediction.

Answers

Answer:

The definition is listed in the clarification segment below, and according to the present circumstances.

Explanation:

It undergoes different morphological as well as biochemical modifications mostly during germination. Product contains nutrients and even some hydrolases such as energy, carbohydrates. Owing to the availability of phytic compounds, the seed coat seems to be very durable in nature. Hydrolytic enzymes launch their function by consuming oxygen throughout order to remove this hard coating. In several other processes, including the electron transport system as well as the Kreb process, oxygen also becomes necessary.

The initial phase of germinating seeds requires anaerobic environments where even the enzymes dehydrogenase can function. The subsequent dehydrogenase enzyme brings the electron throughout the electron transport system from either the base to oxygen.  Unless the oxygen frequency is compared with varieties A and B, it can be seen through the analysis that variety B actually absorbed more oxygen. Oxygen intake rates are also depending upon period.The impact of temperature mostly on absorption of oxygen seems to be present. Shift the supply at low temperatures have a low intake of oxygen, while varieties grown over extreme temperatures use much more oxygen. The metabolism of such a seedling is influenced by temperature. Metabolically active young plants display a larger intake of oxygen.

A pair of fruit flies reproduces and has 1000 offspring. All 1000 offspring have the alleles Gg. What is the most likely combination of alleles that each parent has, and why are other combinations not likely.

Answers

Answer:

The correct answer would be - GG and gg.

Explanation:

As it is given that all the 1000 offspring having the same allele Gg which is only possible in one condition that is cross between GG and gg because it is a heterozygous condition in the offspring. So there must be both allele present and it can not be heterozygous parents as there would be a different combinations of offspring in that case.

If the parents either GG only all the offspring would be GG the same with gg than all the offspring will be gg, thus the correct answer would be GG and gg.

Explain at least three ways in which a mutation in an individual's DNA could occur, and describe at least 2 effects a mutation could have on an individual's traits.

Answers

Answer:

Explanation:

Three ways in which mutation could occur are

1) If an error occurs during DNA replication and it's not corrected in time by DNA polymerase.

2) If there is a deletion of a base(s) in the sequence of the DNA. The deletion of a DNA nucleotide/base could also cause a mutation as that could affect the formation of an enzyme or protein useful in building and/processing certain body parts/processes.

3) Thymine dimerization: Thymine dimers are mutations that prevent DNA from replication or even transcription hence preventing a cell from undergoing division (hence causes cancer). They are formed when covalent bonds are formed between the bases of a DNA sequence (somewhere around the carbon-carbon double bond).

The two effects are

1) It could cause cancer as described in (3) above (in the case of thymine dimer)

2) It could lead to deformity in an individual because of the gene that is supposed to code for the last finger has a base deletion, that could eventually lead to the absence of that finger or a shorter or "strange" finger.
