The carbon cycle is the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth.
Margaret [11]3 years ago

Answer: 1 The growth of plants shows that there is a pressence of carbon in the atmosphere. The plants take carbon dioxide and sunlight from the atmosphere for the process of photosynthesis, this provides food to the plants. This food helps in growth and development of the plants and this proves that .

Answer: 2 The carbon exists mainly in the form of carbon dioxide in atmosphere, organic matter in the biosphere and  coal, graphite, diamond in geosphere.

Epithelial tissue can be ____________ according to cell shape and number of layers. one layer of cells is called ____________ ,
alexira [117]

Epithelial tissue is composed of the innervated and avascular layer of cells which are tightly packed. It forms the outermost layer of the body and protects the internal layers and organs.

This tissue can be classified into different categories based on the shape of its cell, and the total number of the layers.

The epithelial tissue with only one layers is known as the simple epithelial tissue.

The epithelial cells that are thin, flat, and scaly are known as the squamous cells.

While the cubodial cells are round or square in shape.

Hence, the given blanks can be filled with classified, simple, squamous, and square.

The nucleoside analogue acyclovir, which is used to treat herpes simplex virus (HSV) infections, lacks a 3′ hydroxyl group (–OH)
Dima020 [189]

Answer:

There won't be any functional viral DNA synthesis

Explanation:

First of all, you must consider that the HSV has a double-stranded, linear DNA genome. Furthermore, the DNA skeleton is made of the 5'-3' phosphodiester bond. In other words, the 5-phosphat of a nucleotide will bond the 3' OH of the Deoxyribose (see image).

Therefore, if you add a molecule which lacks the 3' OH, such as acyclovir, and has a similar chemical structure to a regular nucleotide, the DNA polimerase will be able to add acyclovir to the main backbone of the viral genome. All in all, you'd be ''cheating'' the DNA pol.

Hence, wherever acyclovir was integrated, there won't be any chance to form a 5'-3' phosphodiester bond. The protomolecule will not be stable and will soon be degradated.
