What are viruses considered to be non-living?

BARSIC [14]

Answer:

Viruses are often considered non-living because outside of a living cell, they do not exhibit the characteristics of living organisms: they are basically like crystals. But within a living organism, they become activated and are able to carry out life's activities like replication (a form of reproduction).

Image 1.1 -

Stomata are little moth-like structures in leaves, that, when open, allow the exchange of gases between the plant and the exterior.

Answer:

B.

Image 1.2 -

Without the existance of stomata, the process of transpiration wouldn't be possible if there weren't structures thata allowed the exchange of gases.

Answer:

A.

Image 2 -

So, we can elminate plants because they can photosynthesise; bacteria because they are prokaryotes and can photosynthesise; archaea because they are prokaryotes; hat leaves us with animals and fungi because these cannot photosynthesise and are both eukaryotes.

But, we cannot skip information. It is also said that the organism found has a cell wall, and animals do not have cell walls.

Answer:

C.

Image 4 -

Option 1 = cilia

Option 2 = flagella

Option 3 = pseudopods

Option 4 = pili (they're a meant to attacht to surfaces only bacteria)

Image 5 -

Runner stems are those that grow horizontally, therefore the fourth image with the long horizontal stems.

Rhizome stems are underground stems that can form roots or shoots through their nodes. Therefore, the third image with white background (the one with 2 drawn plants).

Tuber stems are large underground (mostly) structures used as storages for the plant. Therefore, this corresponds to the first image (the one with the white background.

Bulb stems are short and "bulby" stems, whith thick, leaves. Therefore, the second image (the one with the grass background).

Hope it helped,

Ras is a g-protein that is activated when a growth factor attaches to egfr. its activation results in the replacement of a gdp m

kodGreya [7K]

Answer:

A mutation in Ras protein which will cause hyperactivity will eventually lead to cancer.

Explanation:

Ras protein was first discovered in Rous sarcoma virus (RSV) and it is a proto-oncogene product. In normal conditions, it plays an important role in cellular signalling but in case of gain of function/hyperactivity it gets converted into cellular oncogene. In several types of cancers a point mutation has been reported in Ras protein.

Just like G protein, it is also a GTPase switch protein but unlike G protein which is trimeric, it is monomeric. In the plasma membrane, it is attached with the help of lipids like prenyl or palmitoyl groups. During signal transduction pathway when it gets activated, it downstream activates MAPK pathway and causes gene expression but when it gets hyperactivated it causes over expression of genes leading to cancer.
