Bacteria are extremely successful and resilient life forms, and they are designed to be adaptable to their environment. Some adaptation of bacteria only last as long as certain pressure is exerted over them, and thus are reversible. Others are permanent. Four features of bacteria that enable them to survive in a wide variety of habitats are:

  • Bacteria can adapt to changes in temperature and pH.
  • Bacteria can form adherent populations on solid surfaces (biofilm).
  • Chemotaxis (occurs when a bacterium senses the chemical composition of the environment and moves toward or away from compounds).
  • Bacteria have a basic sort of "memory" that compares different situations  at different times.

<h2><u>Answer:</u></h2>

The 4 principle requirements for microorganisms survival are:

1) Food

2) Moisture

3) Warmth

4) Time

There are microscopic organisms that can develop in cold temperatures and some that blossom with warm temperatures.

A few bacteria go after the other microscopic organisms for survival. Different microscopic organisms get by getting supplements from dead items. Some microorganisms use photosynthesis to make their nourishment.

How does a catalyst work? using these options...
Gelneren [198K]

Answer: D) By decreasing the activation energy of a reaction

A catalyst is a substance that speed up the rate of chemical reaction without affecting the product of the reaction. They only affect the rate of reaction not the yield of reaction.

Catalyst provide an alternative reaction pathway that has lower activation energy  than that of uncatalysed reaction. It increases the frequency of collision and because of these greater collision which lowers the activation energy of the reaction.

In corn, red kernel color (R) is dominant to yellow (r) and smooth kernel texture (W) is dominant to wrinkled (w).
Wewaii [24]

Answer:

a. df =  3, chi-square = 1.7333, p value = 7.815

b. we fail to reject null hypothesis

c. it is independent of kernel texture

Explanation:

h0; there is independence

h1; no independence

9:3:3:1 this is the phenotypic ratio

9+3+3+1 = 16

330 red smooth  + 97 red wrinkled  + 101 yellow smooth  + 32 yellow wrinkled

total observed = 560

1. the degree of freedom = n-1

n =4, 4-1 = 3

to get the chi square computation

(O-E)²/E

expected value for red smooth,

9/16 x 560 = 315

chisquare = (330-315)²/315 = 0.7143

expected for red wrinkled

3/16*560 = 105

chisquare = (97-105)²/105 = 0.6095

expected for yellow smooth

3/16*560 = 105

chisquare = (101-105)²/105 = 0.1524

expected for yelow wrinkled

1/16 * 560 = 35

chisquare = (32-35)²/35 = 0.2571

total chisquare = 0.7143+0.6095+0.1524+0.2571

= 1.7333

with probability = 0.05, df = 3, the value of the chi square from x² table = 7.815

1.7333 < 7.815

so  we fail to reject the null

c. we conclude that kernel color is independent of kernel texture

How would the specific gravity of urine be different after a vigorous workout without the consumption of significant quantities
Zina [86]
After a vigorous workout without consuming significant amounts of water, the specific gravity will have a higher concentration. A vigorous workout increases the breakdown of glucose, without enough water to flush it out it remains in the urine;meaning specific gravity will be high because of the of the high glucose content.
