Cadaver Decomposition Island

-  When a body is buried directly in the soil, then it is subject to decomposition by insects and microorganisms. 

<span>- </span>During this process, a self-digestion of the cells occurs as well as anaerobic decomposition of animal proteins resulting in a release of various chemical components.

<span>- </span>This nutrient-rich fluid is trapped in the soil matrix for a long period of time resulting in the formation of Cadaver Decomposition Island

<span>- The formation of Cadaver Decomposition Island is associated with increased microbial biomass and activity.</span>

Before a captive breeding program and subsequent reintroduction of the black-footed ferret it is believed that their total popul
irga5000 [103]

Answer:

a) 99.93%

b) 99.98%

Explanation:

Given that:

Total population size was only around 18 individuals ( for  black-footed ferret)

If the annual survival rate in the wild was 0.4%.

a)

What is the probability that all 18 would have died in a single year?

To find that; we multiply the annual survival rate in the wild with the total population; which is:

(0.4%×18) = 0.072%

Then; we subtract it from a total of 100% in order to determine the probability that all 18 would have died in a single year.

= (100.00% - 0.072%)

= 99.93%

b)

What is the probability that all 18 would have died in a single year if canine distemper was present?

Given that;

Because of the presence of canine distemper disease, the annual mortality rate might have been as high as 0.89.

To determine the probability; we have:

1 - Annual mortality rate = annual survival rate

1 - 0.89 = 0.11 %

Therefore, 0.11% of 18 individuals = (0.0011 × 18)

= 0.0198%

Probability that all 18 would have died in a single year if canine distemper was present = 100 - probability of annual survival rate

= (100 - 0.0198)%

= 99.98%

The table below summarizes Mendel’s results for the F2 generation. Mendel’s Results Plant height 787 tall 277 short Flower color
Gnom [1K]

Answer:

2001

Explanation:

This question showcases a table that displays Mendel's results (figures) when he crossed pea plants and observed different characters in the plant. Mendel worked with different phenotypic characteristics in the pea plant.

According to the table, the result were for seven characteristics including height, flower color, flower position, pod color, pod shape, seed color, seed shape. Based on the observation of the number of F2 offsprings that possessed dominant trait and recessive trait for each character, we will notice that it follows an approximate phenotypic ratio of 3:1

1. Plant height 787 tall 277 short (3:1)

2. Flower color 705 purple 224 white (3:1)

3. Flower position 651 middle of stem 207 end of stem (3:1)

4. Pod color 428 green 152 yellow (3:1)

5. Pod shape 882 inflated 299 constricted (3:1)

6. Seed color 6,022 yellow X green

7. Seed shape 5,474 smooth 1,850 wrinkled (3:1)

This 3 dominant : 1 recessive ratio is the ratio got in the F2 offsprings when he observed the seven characteristics in pea plants. Hence, the seed color will also follow the same 3:1 ratio

Therefore, 2001 is the result Mendel obtained in the F2 offsprings for the recessive trait of seed color characteristics in his experiment, which actually depicts the 3:1 ratio. Hence, X (green seed color) is 2001

Minerals can a. provide energy to the body. b. become part of the body's structural systems. c. be degraded by the body. d. be d
slamgirl [31]

Answer:

b. become part of the body's structural systems.

Explanation:

  • Minerals are the inorganic regulators needed for different functions inside the body.
  • Minerals donot provide energy but involved in generation of energ through their metabolic function. (Hence option A is excluded)
  • They provide a good medium for the protoplasmic activities (permeability of cell membrane and normal functioning of cell)
  • Maintaining bod fluid balance.
  • For structural units.
  • Cannot be degraded in the body neither can be destroyed while cooking ( Hence option c and d are excluded)
  • They become the part of the body's strctral systems (Hence option B is the right answer)

In eukaryotes, the size of the primary transcript is generally ________ the gene in the template dna strand.
Hunter-Best [27]
Had to look for the options and here is my answer. 
Basically, when we say eukaryotes, these are kinds of organisms which consists of cells that has DNA and other organelles that are enclosed by a membrane. In this case, the size of the primary transcript is generally THE SAME LENGTH the gene in the template of the DNA strand. Hope this helps.
