Answer:

proteins called expansins

Explanation:

The complete question is :

<em>According to the acid-growth hypothesis, auxin causes increased acidity in cell walls, which then activates ____ that disrupt(s) bonds between cellulose microfibrils, allowing cell expansion.</em>

<em>a. a membrane potential </em>

<em>b. an mRNA </em>

<em>c. AUX1 transporters </em>

<em>d. K+ ions </em>

<em>e. proteins called expansins</em>

<em></em>

  • The acid growth hypothesis explains the growth of cells and organs in the plants.
  • According to this hypothesis, the plant hormone auxin causes induction of the H+ proton extrusion into the apoplast which leads to the activation of expansin which a pH-sensitive protein.
  • Expansin is responsible for wall stretching and relaxation and causes hydrolysis of hydrogen bonds and thus helps in cell expansion.

Consider the models of cell reproduction. Evaluate the statements and select ALL that are NOT supported by the models.
Novosadov [1.4K]

Answer and Explanation:

The cell division cycle is responsible for increasing and maintaining cell number and size. This cycle is an essential feature of living organisms. There are four phases of cell division mitotic phase (M phase), growth phase 1 (G1), growth phase 2 (G2), and synthesis phase (S). One phase of the cell cycle ends, and the other starts; this is named a phase transition—a unidirectional alteration in the cell cycle phases. During G1, G2, and S phase cell grows and during the M phase cell divides. There are two models of cell reproduction as the clock model and the domino model. The domino model implies that cell division phases must occur in a distinct order and at a definite time. The domino model recommends that the cell cycle events are independent, while the clock model shows that the effectiveness of mitosis entrance was not persuaded by other actions.

An area of raised land in the middle of a river. Mountains and glacier in the distance. A geologist finds this ridge of sediment
Nadusha1986 [10]

A moraine is a landform feature which is formed by the glacier retreating. The ridge of sediments that geologists found has a feature namely moraine.

<h3>What is moraine?</h3>

The materials usually soil or rocks left behind by the glaciers are called moraine.

Just like rivers that carries all sorts of debris and silt and eventually builds up to form deltas, similarly glaciers moves all sorts of dirt and boulders that assembles to form moraines.

As the geologist found a ridge of sediments and notices a glacier in the distance so this is the moraine.

Thus, the correct answer is C.

A) Explain why antibiotics would kill a prokaryotic cell. (2 points)
lisov135 [29]

Answer:

Antibiotics are simply chemicals that kill prokaryotic cells but do not harm eukaryotic cells. They are natural chemicals produced by fungi and bacteria that act to control their bacterial competitors. For example, streptomycin stops protein synthesis in prokaryotic cells by binding to their unusual ribosomes.

Explanation:

Sorry if this makes no sense. Basically, the antibiotics will harm/kill cells like the prokaryotic cell, but it won't harm or kill any human cells that are essential. They'll kill bacteria, though. The chemicals in the antibiotics aren't compatible with the ones in the prokaryotic cell, so it'll kill it.
