impact of climate change on ecosystems in Karnataka
right answer will be awarded

Answers

Answer:

Explanation:

Flanked by the Arabian Sea, Karnataka is a coastal state in

the south west of India. It is the eighth largest state by size

and the ninth by population.While the Western Ghats

account for a bulk of the state’s forest cover, over 77 per cent

of its geographical area is arid or semi-arid. Much of this is

concentrated in North Karnataka. Karnataka is also the third

most urbanised state in the country and water availability is a

major concern. In terms of its economy, over 50 per cent of the

state’s Gross State Domestic Product comes from the services

sector.  There has, however, been a dip in manufacturing and a

reduction in mining and quarrying operations.

Much of Karnataka’s environmental legacy revolves around two

issues; industrial activity in the Ghats in the form of paper mills,

gold and iron mining, and hydro power generation; and the

supply and usage of water.10 The most notable manifestation of

the latter is the Cauvery water dispute between Karnataka and

Tamil Nadu.11 A related concern is the sharp disappearance of

lakes and water bodies, owing to encroachment, pollution and

infrastructural activity in the state. Karnataka has a number of prominent scientific and researchbased institutions based in its capital city Bengaluru (formerly

Bangalore) and this has played an important part in the framing

and content of Karnataka’s SAPCC.

B Mutations increase the genetic variation within a population, and some of the variants may provide an advantage to individuals over time
C Mutations help stabilize the genetic variation within a population, and only one or two variants generally provide an advantage to individuals.
D Mutations help reduce the genetic variation within a population, and thus increasing the rate that new adaptations develop.

Answers

Answer:

B. Mutations increase the genetic variation within a population, and some of the variants may provide an advantage to individuals over time

The role of mutations in evolution by natural selection is option b. Mutations increase the genetic variation within a population.

Role of mutation in evolution:

The mutation is significant as the first step of evolution since it developed the new DNA sequence for the specific gene that developed the new allele.

Also, at the same time, it rise the genetic variation within the population also it provides as an advantage to individual

helium is an element..............

Answer:

A. Element

Explanation:

He is a symbol of an element called helium. Helium is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas (gas whose atoms are not bound to each other). It's the first in the noble gas group in the periodic table. As we can see in the attached image, its atomic number is 2.

Helium is known for causing people to have a high-pitched voice after being inhaled. Because it is lighter than air, when you inhale it and try to talk, the sound waves travel faster through the lower-density gas, resulting in a high-pitched voice.

A 3 base section of mRNA. The ribosome reads 1 codon at a time; translation of a new protein always begins with _________, or Methionine, the START codon, and ends with a STOP codon.

Answers

Answer:

The start codon is AUG

Explanation:

A three nucleotide sequence (represented with bases) of a DNA or a RNA which translates to a specific amino acid is referred to as codon. To begin the translation into a new protein, the first three nucleotide is always AUG (called the START codon) which is the codon for methionine.

NOTE: AUG is the initial of the bases; Adenine, Uracil and Guanine
