A change in the responsiveness of the sensory system based on the average level of surrounding stimulation is called sensory ___
vagabundo [1.1K]

Answer:

Sensory adaptation.

Explanation:

  • An exposure to constant or prolonged stimulus will slowly decrease our response.
  • For example, when we rested our arm or hand on the table then the surface of the table will abruptly feel against our hand.
  • Sensory adaptation helps us in daily life work by decreasing our response to constant stimulus that's why we give our attention to other environmental aspects. If our response will remain constant to prolonged stimulus then we can't detect new or important environmental aspects.

Which statement correctly describes cancer formation?
AleksandrR [38]

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).

Unlike in prokaryotic cells, replication in eukaryotic cells
elena-14-01-66 [18.8K]
<span>a. is continuous in two directions until the whole chromosome is copied.

</span><span>The two identical daughter cells resulting from mitosis and cytokinesis are identical in the following ways:1. Mitosis occurs when the nucleus of the cell divides into two identical nuclei, each with the same type and number of chromosomes. The cell's DNA is duplicated during this phase. Sometimes the cell's DNA isn't copied properly resulting in cancer-type cells. 2. Cytokinesis is when the cytoplasm divides into two identical daughter cells. Each cell is genetically identical and both are a similar size. </span>

Carbohydrate residues attached to the membrane lipids are always positioned on the extracellular side of the membrane

Carbohydrates are significant parts of the cell membrane, present just on the external surface of the plasma layer, and are appended to proteins, framing glycoproteins, or lipids, and framing glycolipids. These carbohydrate chains might comprise 2-60 monosaccharide units and can be either straight or branched.

The carbohydrates of the membrane are engaged with cell bond and acknowledgment and go about as a physical barrier. Enormous, uncharged particles, for example, glucose can't diffuse through the membrane.

These carbohydrates structure particular cell markers, that permit cells to perceive one another. These markers are vital in the resistant framework, permitting safe cells to separate between body cells, which they shouldn't assault, and unfamiliar cells or tissues, which they ought to.
