Auxin is the molecule which is related to the phototropism of the plants. In the mutant plants, which do not have hormone auxin, do not respond to light. It activates proton pump, and leads to the decrease in the pH of the leaf. This acidification breaks cell wall structure and cell wall become less rigid, and thus, can bend towards the light, by exerting mechanical pressure.

g100num [7]

In the given scenario, the weather model is showing light rain, the correct option is B.

<h3>What is a weather station model?</h3>

Current weather circumstances, cloud cover, wind speed, prevailing winds, visibility, heating rate, dew point temperature, atmospheric pressure adjusted to sea level, and pressure change over the last three hours are all depicted in the station model.

As we discovered, the station model is a method of displaying a large amount of weather data on a single area using numbers and symbols.

Meteorologists can quickly glance at the map and see a lot of information this way.

In the given image, the three inverted commas are representing moderate drizzles.

Thus, the correct option is B.

Troyanec [42]

Answer:

Cells are the smallest unit of life. This is true.

Cells are important to the structure and function of living things. This is true.

All organisms are made of multiple cells. This is false, because there are many single celled organisms like bacteria.

Cells come in different shapes and sizes. This is true, as there are cells with a variety of shape and size (round shaped cocci and the elongated and flat bacillus). There are cells from squid's nervous system, called the neurons, that are comparatively very large in size than the vast majority of the other cells.

What part of the female system is the usual site of fertilization of the ovulated oocyte?.
Paul [167]

Fertilization of the egg cell by the sperm usually takes place in the fallopian tube. The fertilized egg then travels to the uterus and implants in the endometrium.

<h3>What are fallopian tubes?</h3>
  • Fallopian tubes are also called oviducts or uterine tubes. It is the passage through which the egg enters the uterine cavity from the ovary.
  • Fallopian tubes are part of the reproductive tract. They have a smooth muscle wall, an inner mucous membrane, and an outer layer of loose supporting tissue (serosa).
<h3>Why does fertilization take place in the fallopian tubes?</h3>

The fallopian tube (oviduct) regulates fertilization through sperm induction and sperm hyperactivity. Sperm induction is achieved by rheotaxis, thermotaxis, and chemotaxis. Rheotaxis is caused by tubal fluid that creates a current flow from the tubal ampulla to the tubal isthmus.
