Which statement correctly describes cancer formation?

Biology
1 answer:
AleksandrR [38]3 years ago
4 0

Answer:

Cancer is formed when there are mutations in a number of genes.

Explanation:

Malignant tumors are gene diseases which do not mean that cancer is necessarily an inherited disease (only in 5-10% of cases the cancer is inherited) because the vast majority of other tumors are the result of somatic, ie secondary, mutations that lead to malignant transformation.

Only 2% of human diseases are monogenic (caused by a change in one gene). The remaining 98% of the disease is either polygenic (caused by a change in several genes at the same time) or epigenetic (caused by non-genetic or post-genetic disorders of cellular molecules).

Why are cellular respiration and photosynthesis considered opposite reactions
Andreas93 [3]

Explanation:

They are opposites because they are the same chemical reaction but reversed. Cellular respiration takes glucose (from nutrient/food) and oxygen (from atmosphere) in order to make CO2 (think about exhaling) and H20 (water).

Mice21 [21]
The linear sequence that passes energy from one organism to another is called the food chain. The energy is transferred starting from the Sun which is necessary for the plant's photosynthesis then move towards animals consuming plants as food. This is usually followed by humans eating animals like pigs and chickens for food.

Forests, mountains, rivers, and marshes are examples of the wide variety of ecosystems in net york state. The diversity of these
seropon [69]

The main answer is Climate. Here's why:

The climate of different places can be hot, cold, or just right. Because New York is on the eastern side of the United States (which is a very rainy place), there is enough water for forests, marshes, and rivers. There are mountians because of the land being above sea level, likely caused by erosion or earthquakes.

Unlike eukaryotes prokaryotes do not contain a system of internal membranes. Any organelles, proteins, and genetic material are
Schach [20]

Answer:

The difference in protein synthesis in prokaryotic and eukaryotic cells, due to the compartmentalization of the latter, is that transcription and translation can occur simultaneously in a prokaryote but not in a eukaryote (option C).

Explanation:

Eukaryotic cells are characterized by a true nucleus, surrounded by a nuclear membrane. Since transcription occurs in the nucleus and translation for protein synthesis occurs in the cytoplasm, the former process occurs before the latter.

In prokaryotic cells the absence of a nucleus and compartmentalization system makes it possible for<em> transcription of DNA into RNA and translation to occur simultaneously</em>.

The other options are not correct because:

<em>     A. RNA processing, in both prokaryotes and eukaryotes, occurs in the cytoplasm.</em>

<em>     B. Transcription precedes translation in all organisms.</em>

<em>     D. Ribosomes are present and are necessary for protein synthesis in both prokaryotes and eukaryotes.</em>
