Which statement best describes cancer cells?
They grow as a single layer of cells.
They cease to reproduce after 20–50 mitotic divisions.
They reproduce only when needed to replace missing cells.
They are not regulated by contact inhibition.

Answers

Answer 1

Answer: They are not regulated by contact inhibition.

Explanation:

Contact inhibition is a form of controlling cells. Cancer doesn't have contact inhibition, which is one of the reasons why it spirals out of place so easily.

Answer 2

Answer:

They are Not regulated by contact inhibition.

Explanation:

The other 3 options are not characteristics of a cancer cell. Cancer cells have unlimited cell division, no anchorage dependent inhibition, no contact inhibition, and forms tumors - hence they don't form a single layer of cells.

Within the mitochondrial matrix of mitochondria, the Krebs cycle occurs. In the cytoplasm of the cell, glycolysis happens, hence option C is correct.

What is Krebs's cycle?

The Krebs cycle processes occur in the mitochondrial matrix, a dense solution that surrounds the mitochondrial crests in eukaryotes. In addition to water, the matrix also includes all the enzymes, coenzymes, and phosphates required for the cycle's biochemical reactions.

While the majority of anaerobic (without oxygen) and aerobic (with oxygen) respiration respectively occurs in the cytoplasm and mitochondria of the cell.

The cycle occurs in the mitochondrial matrix and results in the production of chemical energy in the forms of ATP, FADH2, and NADH.

Therefore, in the mitochondrial matrix of mitochondria, the Krebs cycle occurs, hence option C is correct.

Why is it more common for birds to have nests with a few eggs rather than just one or a lot?

Answers

Explanation:

The large size of a egg makes it difficult for the female to retain more than a single one egg at a time - carrying eggs would make flying harder and require more energy. (Bird eggs vary in size from the tiny 0.2 gramme eggs of hummingbirds to the enormous 9 kilogram eggs of the extinct elephant bird.)

Just as an aircraft cannot fly if it is overweight, all female birds must dispense with the fertile egg as soon as it is formed. And because the egg is such a protein-rich high-nuitrition prize to all sorts of predators, birds must find a secure place to hatch their eggs. Although birds' eggs appear to be fragile, they are in fact extremely robust. The oval shape applies the same rules of engineering as an arched bridge; the convex surface can withstand considerable pressure without breaking. This is essential if the egg is not to crack under the weight of the sitting bird. It takes 26 pounds of pressure to break a swan's egg and 120 pounds to smash the egg of an ostrich.

Female birds have one working ovary, unlike mammals, which have two. Ovaries are the organs where eggs are produced. A bird's ovary looks like a tiny bunch of different-sized grapes.

how does the action og wind affect a rock appearance

Answers

Wind causes the lifting and transport of lighter particles from a dry soil, leaving behind a surface of coarse grained sand and rocks. The removed particles will be transported to another region where they may form sand dunes on a beach or in a desert. Wind erosion is referred to as eolian erosion. Differences in atmospheric pressure will cause the motion of air that can erode surface material when velocities are high enough to move particles.

How does the information from the stimuli get communicated to the brain?

Answers

Answer:

Explanation:

Sensory receptor interact with stimuli, such as light sound temperature and pain which is transformed into the code that is carried to the brain by the chain of neurons. Once the signal reaches the end of an axon, which is at the end of neuron, a neurotransmitter is released and the process repeats.

The information is sent in the form of nerve impulses and reaches the spinal cord through the sensory neurons of the PNS.

Metal are malleable and ductile. Explain on the basis of the electron sea level?

Answers

ANSWER:__________________________________________________Metallic Bonding:

Metallic Bonding is restricted to metals only. In the metallic bonding, There is a electrostatic force of atrraction between the metal ions (which are positive)

and the electrons(which are negative).

The metal ions are arranged in a lattice pattern which is the regular repetitive structure.

_____________________________________Electron Sea Level:

Every metal atom donate one or two valence electrons, so due to the BULK presence of the electrons, It results in a formation of sea of electrons. So the valence electrons don't just stay on their own atom, they roam around the whole metal. They are just like a sea of electrons. This is why it is called the electron sea model. basically metal ions are present as a iceberg or island in the freely floating sea of electrons.

_____________________________________How is Sea of electron related to the malleable and ductile property?

The sea of electron works as a electron GLUE, That means the metal ions are strongly ATTRACTED to the electron, so When apply pressure on the metals they DONT BREAK that means they are not brittle but malleable and ductile. This is because of the moving electrons and because the cations slide easily past each other, The ability of the atoms to roll over each other into new positions without breaking the metallic bond is because of the electron glue.

_____________________________________IMPORTANT STATEMENTS

Brittle; Hard but breakable due to absence of sea of electron.

Malleable and Ductile; Transformed into sheets and thin wires so they are somewhat ELASTIC.

Why do you think surface waves are the slowest moving waves?

Answers

Answer:

S waves are more dangerous than P waves because they have greater amplitude and produce vertical and horizontal motion of the ground surface. The slowest waves, surface waves, arrive last. They travel only along the surface of the Earth.

Explanation:

Answer:

They move a little more slowly than P waves, and can only pass through solids. As S waves move, they displace rock particles outward, pushing them perpendicular to the path of the waves. ... Surface waves are the slowest moving of all waves, which means they arrive the last

Electron Carriers (NADH and FADH2), ATP, and Carbon Dioxide.

Hope this helps!

Answer:

What are the Krebs Cycle products? Electron Carriers (NADH and FADH2), ATP, and Carbon Dioxide.

Explanation:

For one cycle, two molecules of carbon, three molecules of NADH, one molecule of FADH2 and one molecule of ATP or GTP are produced. Each glucose molecule produces two molecules of acetyl CoA, enough for two cycles. These products can be multiplied by two to produce the per-glucose yield. Though only one ATP (or GTP) is produced directly per cycle, the products NADH and FADH2, can produce ATP (or GTP) in a further process of cellular respiration called oxidative phosphorylation. The main function of the Krebs cycle is to produce energy, stored and transported as ATP or GTP. The cycle is also central to other biosynthetic reactions where the intermediates produced are required to make other molecules, such as amino acids, nucleotide bases and cholesterol. The Krebs cycle is found in all cells that use oxygen. Combined with the process of oxidative phosphorylation, the Krebs cycle produces the majority of energy used by aerobic cells with the percentage energy provided for humans being greater than 95%.

The study of genes and inheritance is called genetics. In a gene pair, one allele is dominant and the other is recessive.

The correct answer is the variation in gene combination.

What is polygenic inheritance?A character that is controlled by more than one pair of alleles is called polygenic inheritance. The best example is skin pigmentation which is controlled by 6 alleles or 3 gene pairs.

According to the question, pigmentation is different due to the combination of the different genes. These genes produced melatonin which decides the skin tone, The dominant genes code for a darker tone, and the recessive gene code for a lighter tone.

Hence,  the correct answer is mentioned above.

The crossing of a hybrid and a dominant purebred will always result in offspring which are what?

Answers

Answer:

Dominant

Explanation:

A hybrid trait is also known as heterozygous, which is the combination of the dominant and recessive alleles of a gene. On the other hand, a purebred is combination of the same two dominant alleles or the same two recessive alleles. For example, in the gene coding for height, allele for tallness (T) is dominant over the allele for shortness (t).

A purebred for this trait will either be "TT" or "tt" while a heterozygous or hybrid will be Tt. Hence, according to this question, crossing of a hybrid (Tt) and a dominant purebred (TT) will always result in offspring which are DOMINANT (see attached image).
