Answer:

The procedure is present below.

Explanation:

Take four pots having mint plant with same sizes and then apply 2% salt to pot no.1, then apply 5% salt to pot no.2, apply 10% salt to pot no.3, and apply 15% salt to pot no.4. After a 1 week or 2, see the growth of the mint plants. You will notice some mint plants are not effected to salt concentration because they are present in low quantity whereas some plants experience stunted growth due to higher concentration of salt which is unbearable for the mint plant.

Was the streak plate method effective at diluting the population size in all 4 plates?
Inessa05 [86]

Answer:

"Yes" The streak plate method is very effective in diluting the population size in all 4 plates.

Explanation:

The streak plate method is effective because it is one among the rapid isolation method which further allows for easy observation of the bacteria. This method is also being used for getting the color of the certain substances. Its main principle is to isolate the specific bacteria from the sample of various microbes. It dilutes the microbes number and often reduces their density. It is useful in separation of organisms from the group. These are isolated in the agar plate.

Today I.d.k what to ask. I asked what is wrong with me because I am lactose intolerance, and basically I hate milk, and why are
harina [27]
Our bodies produce an enzyme called lactase. This enzyme helps our bodies digest lactose (a sugar found in milk). As we age, the amount of lactase our bodies produce decreases. Some people don’t produce as much as others. If you are lactose intolerant, it means your body doesn’t produce a lot of lactase. One option is to drink milk with lactase added to it.

A geneticist is studying two traits in the fruit fly - eye color and wing shape. They perform a dihybrid cross. If the genes for
Len [333]

Answer:

3/16

Explanation:

<u>According to Mendel's law of independent assortment of genes, when a dihybrid cross involves two genes that assort independently and one of the parents is dominant for the two genes and the other is recessive, the phenotypic ratio of the offspring at F2 would be 9:3:3:1</u>. The proportion of the offspring with the dominant parental traits would be 9/16, those with the recessive parental traits would be 1/16, while those with mixed traits would be 3/16 each.

Assuming the eye color is represented by E and the wing shape is represented by W. At F2

     EeWw    x    EeWw

E_W_ - 9/16 (dominant for both eye color and wing shape)

E_ww - 3/16 (dominant for eye color and recessive for wing shape)

eeW_ - 3/16 (recessive for eye color and dominant for wing shape)

eeww - 1/16 (recessive for both eye color and wing shape)

<em>Hence, the proportion of the offspring with dominant phenotype for eye color and recessive phenotype for wing shape would be </em><em>3/16.</em>

A food chain or food web can provide good information including _____. how much energy is transferred from one organism to anoth
Artemon [7]

Answer: A food chain or food web provide information on the eating patterns of organisms, how energy is transfered from one organisms to another and the flow if energy in the ecosystem.

Explanation:

Food chain is the link of network that that starts from producer to the consumer and finally ends at the predator species and decomposer species in the ecosystem. It describe the feeding relationships among organisms.

Food web contains interconnection of several food chains in the ecosystem. It shows several feeding relationships in food chains .

Both food chain and food web provide information of how organisms are interconnected, their eating patterns, how energy is transferred from one organisms to another and flow of energy in the ecosystem.
