What are the advantages and disadvantages of wildlife conservation?

Biology
1 answer:
Setler [38]3 years ago
5 0

Answer: Wildlife conservation preserves animals, plants, and trees from destruction. It also creates jobs and allows us to learn more about the environment because we can further study the plants and animals. A disadvantage might be the time and money used to do this.

Feeding scrub-jays can lead to starvation of fledgling scrub-jays.
Lilit [14]

The statement “Feeding scrub-jays can lead to starvation of fledgling scrub-jays” is true because if humans feed the birds, they may become reliant on humans and be unable to get their own food, which can lead to starvation and malnutrition

Which pathway is affected by an inherited mutation in the atm gene?
Katena32 [7]

The question is incomplete as it does not have the options which are:

photoreactivation

reactivation repair pathway

nucleotide excision repair pathway

UV repair pathway

p53 repair pathway

Answer:

p53 repair pathway

Explanation:

ATM gene or ataxia telangiectasia-mutated is a gene which codes for the protein kinase involved in the DNA double-stranded break.

The DNA double-stranded break is repaired easily as the protein kinase is recruited to the site of the break where it allows the DNA repair machinery to repair the DNA.

The gene also controls the cell growth therefore this gene is important to study cancer.  Since the p53 protein is a suppressor protein which if mutated is repaired by the ATM gene and if the gene becomes mutated then the p53 repair pathway is affected.

Thus, p53 repair pathway is the correct answer.

One g of fecal matter was suspended in 99 ml saline solution (tube 1). After mixing gently but thoroughly, one ml from tube 1 wa
malfutka [58]

Answer: the cfu/g Gram-negative bacteria in the fecal sample is C = 3.0 × 10^3

Explanation:

We know that; Gram negative bacteria looks  pale reddish in color under a light microscope from Gram staining.

therefore

There are 30 red bacterial colonies counted.

1 mL of from tube 1 was removed and added to tube with 99 mL saline (tube 2) dilution is 1/100.

transferred volume  into the plate is 1 mL.

Now, we have to determine the cfu/g Gram-negative bacteria in the fecal sample

Formula to calculate CFU/g bacteria in fecal sample is expressed as;

C = n/(s×d )

where C is concentration (CFU/g) , n is number of colonies , s is volume transferred to plate , d is dilution factor.

so we substitute

C = 30 / ((1/100) × 1)

C = 30 / 0.01

C = 3000

C = 3.0 × 10^3

THERFERE, the cfu/g Gram-negative bacteria in the fecal sample is C = 3.0 × 10^3
