Before the discovery of cells, people believed in the theory of spontaneous generation. According to this theory, living things

can come from nonliving things. On the basis of this theory, people believed that maggots that formed on cheese spontaneously arose from the cheese. Which two statements disprove this theory of spontaneous generation?
All matter is made of cells.
All living things are made of cells.
Cells are generally microscopic and impossible to detect with the naked eye.
Living cells can only come from previously existing matter.
Cells form from previously existing cells.

The two statements that disapproves the theory of spontaneous generation are:

All living things are made of cells.

Living cells can only come from previously existing matter.

<u>Explanation:</u>

The theory of Spontaneous generation mainly focuses on the fact that Living organisms does not depends on the similar organisms for its regeneration. It states that the living organisms can also be generated by even any non living matters.For examples fleas can be generated from the place where there are dust.  

Dead flesh of any thing can lead to the formation of Maggots. With these example we can conclude that Living cells can only come from previously existing matter is not related to the spontaneous generation theory. The statement that says that all living organisms are made of cells also not associated with this theory.

vichka [17]

Answer:

a. Genotype of male parent= BbNn

Genotype of female parent: bbnn

b: Progeny ratio= 1: 1: 1: 1

c: 1/4

Explanation:

a. Genotype of male parent= BbNn

Genotype of female parent: bbnn

b. Gamete formed by the male parent: BN: Bn: bN: bn in 1:1:1:1 ratio.

Gametes formed by female parent: All gametes with "bn" alleles.

c.  The probability that the offspring will have a genotype of Bbnn=

Bb x bb= 1/2 Bb: 1/2 bb

Nn x nn= 1/2 Nn: 1/2 nn

Therefore, probability that the offspring will have a genotype of Bbnn= 1/2 Bb x 1/2 nn= 1/2.

List some general characteristics of producers and list a few examples.
arsen [322]

A producer is like... a green plant or bacterium (plural for bacteria) and it's part of the first level of the food chain. Phototrophs and chemotrophs are two major producers. Phototrophs use the energy from the sun to convert carbon dioxide into carbohydrates, in other words, photosynthesis. Chemotrophs are almost microscopic- they are found in places where water and light are scarce (or rare) or even not there at all.

Sorry if this isn't any help... I'm trying my best, I don't know much. But if it does help, you're welcome! Have a nice day!

identify the missing numbers below to show the result of multiplying the numbers. (3.5 × 1016)(2.2 × 1010) = a × 10b
11Alexandr11 [23.1K]
<span>In order to find the value of "a" and "b", first of all perform the multiplication in the parenthesis. 
Thus

(3.5x1016) = 3556
and 
(2.2x1010) = 2222

As per question;
(3556)x(2222) = 10 axb
By dividing both sides by "10"
we get
(3556)x(222.2) = axb
or 
(355.6)x(2222) = axb
by comparing both sides of the equation, 
we get that a = 3556  and b = 222.2
or
a = 355.6 and b = 2222

What chemicals regulate the cell cycle how do they work?
Molodets [167]
Cyclins are the chemicals that regulate the cell cycle. Cyclins work by regulating the timing of the cell cycle in eukaryotic cell. Cyclins activates cyclin dependent kinases (CDKs) (an enzyme that works by adding <span>negatively charged phosphate groups to other molecules in a process called phosphorylation) by binding to it to form a cyclin-Cdk complex. This complex then functions by acting as a signal to the cell to move to the next cell cycle phase. At the end of the event, the cyclin is degraded, Cdk is deactivated, therefore signaling exit from a specific phase.</span>
