As the yeast feeds on the sugar, it produces carbon dioxide. With no place to go but up, this gas slowly fills the balloon.

A very similar process happens as bread rises. Carbon dioxide from yeast fills thousands of balloonlike bubbles in the dough. Once the bread has baked, this is what gives the loaf its airy texture.

mina [271]

Answer:

The argument can be contradicted by assuming that both animals and fungi exhibit heterotrophy and have intracellular spindles.

Explanation:

If an argument is required to demonstrate that fungi have common characteristics, it can be taken into account that:

  1. <em>They are</em><em> heterotrophic organisms</em><em>, since they are not able to synthesize their own nutrients, such as plants. </em>
  2. <em>Both </em><em>have intracellular spindles</em><em> in their structure, useful when performing the corresponding cell division. </em>
  3. <em>Additionally, both animals and fungi can </em><em>store glycogen</em><em> as a reserve of energetic substrate.</em>

It is currently thought that fungi and animals have a convergent or parallel evolution.

As discussed in Unit 10 of The Physics Classroom Tutorial, electromagnetic waves are waves that are capable of traveling through a vacuum. Unlike mechanical waves that require a medium in order to transport their energy, electromagnetic waves are capable of transporting energy through the vacuum of outer space. Electromagnetic waves are produced by a vibrating electric charge and as such, they consist of both an electric and a magnetic component. The precise nature of such electromagnetic waves is not discussed in The Physics Classroom Tutorial. Nonetheless, there are a variety of statements that can be made about such waves.

makkiz [27]

Answer:

The correct answer will be-

1. Nucleosomes

2. Chromatin

3. Sister chroamtid

4. Centromere

Explanation:

The DNA is a very long molecule which if has to be passed on to the daughter cell as it is will cause problems. So, to reduce problems a cell form tightly packed structure of DNA so that they can be passed easily to the daughter cell.

The packaging of DNA begins with the wrapping of the DNA around histone proteins which forms the 11 nm basic structural units called nucleosomes. The nucleosomes start condensing each other and form 30 nm structure chromatin fibres.

The chromatin fibres undergo replication during S phase which produces an exact copy of the chromatin called sister chromatids bound to each other at a central point called centromere which helps the separation of the chromatids during M phase.
