Suppose a disease spread through all the red oak trees in a forest economic.
kupik [55]
A: if the oak trees are I'll then it would affect their health which they'll star dying which means that all the biotic organisms that depended on those oak trees for shelter would also start dying which means all the organisms that depended on the oak tree organisms would also die and so on. That way this small change will affect the whole animal community in that area.
B: this change in biodiversity will greatly affect the sustainability of the forest because the animals dying would disrupt the food chain in that ecosystem while killing the whole forest.

A bacterial sample has a cell density of 1.85 x106 CFU/mL. What plate dilution should yield a countable plate? Which two dilutio
insens350 [35]

Answer:

Explanation:

Bacterial count in stock- 1.85x10^6 cfu/ml

Dilution methods

Take 100 uL or (0.1ml) from stock and add to 900ul (0.9ml) saline and mixed it- this makes 10^1dilution.

Now take 100ul from 10^1 dilution and add to next 900ul saline this is 10^2 dilution, similarly do upto 10^5 dilution.

Then take 100ul from 10^ 4 and 10^5 dilution seperately and plate on LB agar plate seperetely and count the colonies.

Cfu/ml formula= (No.of colonies x dilution factor)/0.1 ml

So suppose, 18 colonies formed on 10^4 dilution then total no. Of cells in stock will be 18x10^4/ 0.1= 18x10^5 cfu/ml.

If we dilute 10^4 or 10^5 that's leads to colony count of 18-19 colonies on 10^4 dilution while 2 colonies should come on plate of 10^5 dilution.

Galactosemia is a metabolic disorder characterized by the inability to metabolize the sugar galactose. People with galactosemia
Umnica [9.8K]

Answer:

Genetic mapping for unequivocal identification of the potentially causative mutation  

Explanation:

Galactosemia is a genetic disorder caused by mutations in the Galactose-1-phosphate uridylyltransferase (GALT) gene, which encodes an enzyme involved in the metabolism of galactose. Gene mapping is a technique widely used in genetics to identify the position of one locus a chromosome by using molecular markers to estimate genetic distances. Genetic mapping provides useful evidence in order to identify when a disease that is transmitted from parent to offspring can be associated with one or more genes and then determine which gene/s is/are responsible for this condition.
