Answer:1) Chloroplast, mitochondrion and vacuole are the organelles

Explanation:  a leaf is a organ of a plant and is not found in cells. An enzyme creates chemical reactions in the body. the DNA is just the plan on how to build the cell and how to do certain cellular processes. therefore a chloroplast, mitochondria and vacuole are all organells. also the mitochondrion creates energy, a vacuole stores food and water and a chloroplast converts the suns energy into food

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.

Hypogeal germination is when the plant is germinated under the ground. An example of this would be the pea plant.

epigeal germination is the opposite of that. Germination takes place above the ground. normal bean plants have epigeal germination

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.

Explanation:

Biomagnification, also known as bioamplification or biological magnification, is any concentration of a toxin, such as pesticides, in the tissues of tolerant organisms at successively higher levels in a food chain.[1] This increase can occur as a result of:

Persistence – where the substance cannot be broken down by environmental processes

Food chain energetics – where the substance's concentration increases progressively as it moves up a food chain

Low or non-existent rate of internal degradation or excretion of the substance – mainly due to water-insolubility

In biomagnification the concentration of the persistent toxins (crosses) increases higher up the food chain.

In this scenario, a pond has been intoxicated. As we go further into the food chain, the toxin concentration increases, causing the top consumer to eventually die of intoxication.

Biomagnification is the build up of toxins in a food chain. The DDT concentration is in parts per million. As the trophic level increases in a food chain, the amount of toxic build up increases. The x's represent the amount of toxic build up accumulating as the trophic level increases. Toxins build up in organism's fat and tissue. Predators accumulate higher toxins than prey.

Biological magnification often refers to the process whereby certain substances such as pesticides or heavy metals work their way into lakes, rivers and the ocean, and then move up the food chain in progressively greater concentrations as they are incorporated into the diet of aquatic organisms such as zooplankton, which in turn are eaten perhaps by fish, which then may be eaten by bigger fish, large birds, animals, or humans. The substances become increasingly concentrated in tissues or internal organs as they move up the chain. Bioaccumulants are substances that increase in concentration in living organisms as they take in contaminated air, water, or food because the substances are very slowly metabolized or excreted.

Processes Edit

Although sometimes used interchangeably with "bioaccumulation", an important distinction is drawn between the two, and with bioconcentration.

Bioaccumulation occurs within a trophic level, and is the increase in the concentration of a substance in certain tissues of organisms' bodies due to absorption from food and the environment.

Bioconcentration is defined as occurring when uptake from the water is greater than excretion.[2]

Thus, bioconcentration and bioaccumulation occur within an organism, and biomagnification occurs across trophic (food chain) levels.

Biodilution is also a process that occurs to all trophic levels in an aquatic environment; it is the opposite of biomagnification, thus when a pollutant gets smaller in concentration as it progresses up a food web.

Lipid, (lipophilic) or fat soluble substances cannot be diluted, broken down, or excreted in urine, a water-based medium, and so accumulate in fatty tissues of an organism, if the organism lacks enzymes to degrade them. When eaten by another organism, fats are absorbed in the gut, carrying the substance, which then accumulates in the fats of the predator. Since at each level of the food chain there is a lot of energy loss, a predator must consume many prey, including all of their lipophilic substances.

For example, though mercury is only present in small amounts in seawater, it is absorbed by algae (generally as methylmercury). Methyl-mercury is the most harmful variation of mercury. It is efficiently absorbed, but only very slowly excreted by organisms.[3] Bioaccumulation and bioconcentration result in buildup in the adipose tissue of successive trophic levels: zooplankton, small nekton, larger fish, etc. Anything which eats these fish also consumes the higher level of mercury the fish have accumulated. This process explains why predatory fish such as swordfish and sharks or birds like osprey and eagles have higher concentrations of mercury in their tissue than could be accounted for by direct exposure alone. For example, herring contains mercury at approximately 0.01 parts per million (ppm) and shark contains mercury at greater than 1 ppm.[4]

DDT is thought to biomagnify and biomagnification is one of the most significant reasons it was deemed harmful to the environment by the EPA and other organizations. DDT is stored in the fat of animals and takes many years to break down, and as the fat is consumed by predators, the amounts of DDT biomagnify. DDT is now a banned substance in many parts of the world.[5]

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.

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

hence, the option b is correct.

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
