Answer:

D. deamination of cytosine to uracil

Explanation:

Hydrolytic DNA damage is usually a consequence of metabolic reactions and the most common example of this type of damage is hydrolysis of cytosine into uracil with the release of ammonia. This damage can be fixed by the cell's DNA repair system:removal of uracil  by an enzyme uracil-DNA glycosylase and consequently generation of an abasic (AP) site.  AP endonucleases recognise AP site and break a phosphodiester bond so that lesion can be replaced with another cytosine.

What results from the removal of a phosphate group from ATP?
emmainna [20.7K]

Answer:

The correct answer is the release of energy.

Explanation:

ATP or Adenosine tri phosphate is an energy rich compound .ATP contain 3 phosphate group joined by two high energy phosphoanhydride linkage.

   The hydrolysis of ATP releases the terminal phosphate group or the gamma phosphate group resulting in the formation of ADP and inorganic phosphate(Pi).

 The breakdown of 1 molecule of ATP releases -30.5kj energy which is used to our body to carry out different process such as membrane transport,muscle contraction,biosynthesis of macromolecules.

Aquatic species that can tolerate freshwater and salt water would be well-adapted to which of the following aquatic environments
RideAnS [48]
The appropriate C. Estuary. An estuary is a channel where fresh water from the land interact with salt water from the sea and commonly is affected by ocean tides. The water in an estuary is described as brackish which means it has a higher salt concentration than fresh water and a lower salt concentration than a marine environment.

In a quadrat that is 0.5m along each side, you count 3 daisy
Snowcat [4.5K]

Answer:

Interdependence is a key concept in ecology. Whilst this can be taught theoretically, some practical fieldwork greatly enhances pupils’ understanding. Almost certainly the fieldwork would entail looking at plant abundance and distribution and, of course, some work with quadrats!

A quadrat is a simple device for marking out a small area. For young children at primary school the quadrat is often a convenient way of focusing a pupil’s attention on a particular small area. At secondary level, pupils should understand how quadrats can be used to sample a larger area. By recording information from a number of quadrats placed within a larger study area, they can obtain a representative sample of the whole area, which may be too big to describe in full.

This article describes how quadrats can be used to help pupils at lower secondary level estimate the relative abundance of plant species. All the information given here refers to frame quadrats. (Point quadrats can be tedious and difficult for pupils to use and are probably best avoided at this level.
