True vertebrates have a true head that develops from a neural crest of cells and hard structures surrounding the notochord.
Bond [772]

Yes. True vertebrates have a true head that develops from a neural crest of cells and hard structures surrounding the notochord.

The neural crest, which forms early in the development process in vertebrate embryos, is a fold on the neural plate where the neural and epidermal ectoderms converge. As an embryo grows, the neural crest produces neural crest cells (NCCs), which can differentiate into a variety of different cell types and contribute to tissues and organs.

The notochord is a temporary structure that plays a crucial role in higher animals. It secretes substances that communicate with all neighbouring tissues, telling them where they are and what will happen to them.

Therefore, True vertebrates have a true head that develops from a neural crest of cells and hard structures surrounding the notochord.

Which of the following is a use for a weather radar a. forecasting weather b. preventing precipitation c. measuring rainfall d.
Elden [556K]

Correct answer: A). Forecasting weather

A weather radar is an instrument that is used to locate precipitation, calculate its motion and determine the type i.e hail, snow or rain. It sends electromagnetic energy pulse into the atmosphere. If that pulse of energy interacts with something, then it reflects back the energy, which can be sensed by the weather radar.

Nowadays, most radar used are Doppler effect, which has dual polarization, it determines that movement is toward or away from the radar.

Hence, the correct answer would be option A.

1. Cool, falling air is associated with __________ pressure areas.
ehidna [41]

Answer:

Cool air falls, this is associated with greater pressures areas.

Warm air rises, this is associated with low-pressure areas.

<u>Explanation:</u>

Due to the <em>differences in air pressure</em>, <em>the wind is blown from 'one location to another location'</em>. The cool air is denser than warm air hence the cool air fells which has high density. The warm air has less density and it rises. So the cool air is related to greater pressure areas and warm air is related to lower pressure areas.
