The bacteria must be outcompeted and substituted by bacteria that have gone this genetic factor. In addition, antibiotic resistance is a natural phenomenon.  Once an antibiotic is used, bacteria that can fight that antibiotic have a greater chance of existence than those that are vulnerable. The vulnerable bacteria are exterminated or inhibited by an antibiotic, subsequent to a selective weight for the existence of resilient tensions of bacteria. Around opposition happens without human deed as bacteria can yield and use antibiotics in contradiction of other microorganisms, prominent to a low-level of the natural assortment of opposition to antibiotics. Though, the presently advanced points of antibiotic resilient bacteria are credited to the abuse and abuse of antibiotics.

The observed numbers for dominant and recessive types in an F2 generation are 154 and 46. What would the expected number of indi
katen-ka-za [31]

Answer: Expected heterozygous genotype = 2×46 = 92

Explanation:

According to the hypothesis of segregation of paired genes in heterozygous F1 generation crosses produces 1:2:1 genotype ratio. This means that all these three possible genotypes should be produced in the F2 generation meaning that we have 1(Dominant homozygous) :2 (Dominant heterozygous): 1 (Recessive Homozygous).

Phenotypic ratio shared (dominant: recessive) = 154 and 46

If recessive homozygous phenotype = recessive homozygous genotype = 46

The expected dominant heterozygous genotype= 2 × (recessive homozygous genotype)

= 2 × 46 = 92

10.A 600 kg great white shark is lurking below an observation cage. His movement is
Nadya [2.5K]

The work done by the shark is 128000 J which is greater than the maximum force the cage can withstand (124500 J), the man in the cage should be worried.

<h3>What is work done?</h3>

Work done is the product of force and the distance covered by the force.

Mathematically;

  • Work done = Force × distance

The unit of work done is Joules.

The work done by the shark is calculated as follows:

Work done = 12800 × 10

Work done = 128000 J

Maximum force the can withstand = 124500 J

Since the work done by the shark is greater than the maximum force the cage can withstand, the man in th cage should be worried.

When is lactic acid produced
dedylja [7]
During intense exercise, there may not be enough oxygen available to complete the process, so a substance called lactate is made. Your body can convert this lactate to energy without using oxygen. But this lactate or lactic acid can build up in your bloodstream faster than you can burn it.

hope this helps :)
