Spontaneous generation is the idea that life can emerge from nonliving matter. Spontaneous
many in the scientific community up until the mid-nineteenth century. A series of simple experiments tested the validity of
this idea. Evidence used to
support spontaneous generation was the observation that foods over time became covered in maggots or fungal and
bacterial growth, implying that these just appeared." The inference behind spontaneous generation is that there is no
"parent" organism
In 1668, Francesco Redi proposed a different hypothesis to explain the specific example of maggots that appeared on spoiled
food. Explain how Redi disproved the idea of spontaneous generation and helped contribute to the idea that cells come from pre-
existing cells.
A)
B)
Redi reasoned that maggots appeared after meat spoiled, breaking down
the rotten meat
Redi reasoned that flies laid eggs on meat, so meat kept away from adult

Redi reasoned that meat had to be exposed to air for maggots to appear.
Meat not exposed to air would remain free from maggots.
Redi reasoned that maggots emerged from condensation. As long as the
meat was kept from water sources, there would be no maggots.

Answer 2

Redi reasoned that flies laid eggs on meat, so meat kept away from adult

flies would remain free of maggots it is the example .

What contribution did Francesco Redi make to cell theory?

Redi went on to show that while live maggots or flies will reproduce when placed on decomposing flesh in a sealed jar, dead ones would not. This ruled out the existence of any necessary component in extinct organisms as well as the requirement of fresh air for the creation of life.

In a well controlled experiment, Francesco Redi demonstrated how living things are descended from other living things. The third tenet of the cell theory—that cells originate from other living cells—was developed as a result of this research and that of succeeding researchers.

The prehistoric beliefs were put to the test. Francesco Redi disputed the notion that maggots appeared out of thin air from rotting meat in 1668.

Keisha's fish tank has 13 liters of water in it. She plans to add 4 liters per minute until the tank has at least 41 liters. What are the possible numbers of minutes Keisha could add water? Use t for the number of minutes. Write your answer as an inequality solved for t.

Answers

Answer:

7≥t

Step-by-step explanation:

The tank already has 13litres of water in it.

Keisha plans on increasing the quantity of the water to 41 litres. Hence,

41 litres - 13litres = 28litres

The above implies that she needed 28litres to be added to the fish tank.

She adds 4 litres per minute

Now, the question can now be reframed as how many minutes will be needed to add 28litre.

Considering to proportion method

4litres = 1 minute

28litres = t minutes

4litres × t minutes = 28litres

t = 28/4

t = 7 minutes

Hence, at least 7 minutes will be needed to increase the quantity of the tank water from 13litres to 41litres

But since we are to write the answer in an inequality form.

41≥ 13+4t

Solve for t

41≥13+4t

41-13≥4t

28≥4t

Divide both sides by 4

28/4≥4t/4

A triangle has sides with lengths of 6 feet, 16 feet, and 17 feet. Is it a right triangle?

Answers

No it isn’t a right triangle

Answer:

No.

Step-by-step explanation:

This is not a right triangle. Use the Pythagorean Theorem, [tex]a^{2} + b^{2}=c^{2} \\[/tex], but write it as [tex]c^{2}= a^{2}+b^{2}[/tex]. The hypotenuse would be 17 feet, so you can insert 17 as [tex]c^{2}[/tex]. [tex]a[/tex] and [tex]b[/tex] could be 6 or 16. It can be written either way. The simplified equation would be:

[tex]c^{2}=a^{2} +b^{2} \\17^{2} = 6^{2} + 16^{2} \\17^{2} = 36+ 256\\17^{2}= 292\\289\neq 292[/tex]

This isn't a right triangle.

= 1 / 13

Solve for b. Use (-6, 6)

y = mx + b

6 = 1/13 (-6) + b

6 = -6/13 + b

6 + 6/13 = b

84/13 = b

Substitute the m and b:

y = mx + b

y = 1/13 x + 84/13 or 13y = x + 84

Work out the sizes of angles a, b and c. Give reasons for your answers.

Answers

Answer:

I think that you are wrong with that question

Answer:

a = 50° , b = 60° , c = 70°

Step-by-step explanation:

a and 130° are adjacent angles on a straight line and sum to 180° , then

a = 180° - 130° = 50°

b and 60° are vertically opposite angles and are congruent , so

b = 60°

the sum of the 3 angles in a triangle = 180° , that is

a + b + c = 180°

50° + 60° + c = 180°

110° + c = 180° ( subtract 110° from both sides )

c = 70°
