Give scientists clues about the kind of organisms that lived in an ancient environment

Answers

The answer is a fossil.

The fossil represents a preserved remain of an organism from the past and gives scientists clues about the kind of organisms that lived in an ancient environment.
Usually, hard tissue, such as bones and teeth or exoskeleton is much more preserved than soft tissue (organs, skin, etc.). Fossils become fossils by a process of mineralization. Hard tissues are more mineralized during life than organs. So it is no surprise that hard tissues take part in the process of mineralization and is preserved in fossils, unlike soft tissues

(Answer 1 points 3)

A. Taxon

3. the categories used in classifying organisms.

Explanation:

In other words, we can also say that taxon is also known as a taxonomic group of any rank, such as a species, family, or class. It is a group of one or more than one different populations of an organism or the organisms viewed by taxonomists to make a system. These are the rules for naming new animals.

D. domain

2. The largest taxonomic category.

Explanation:

In the three-domain system of taxonomy, if we talk about the domain then we would define it as the superkingdom or empire. It can also be said to be as it is the highest taxonomic rank of organisms. It is a taxonomic category above the kingdom level. There are three domain such as Bacteria, Archean, and Eukarya, which we can say are the major categories of life.

Which is the most common cause of erosion in deserts? liquid water ice wind plants

Answers

wind; it blows the dirt off of the ground. Plants would stop the erosion; plants would keep the dirt in place. Water and ice are not common in MOST deserts. 

Answer: wind

Erosion is a natural phenomena, in which surface or subsurface soil is removed due to the action of agents like wind, water and others. In deserts sand is the only soil, which is found predominantly. The sand particles does not aggregate and highly porous in nature. The sand particles being lighter in weight are easily blown by the wind currents in the deserts, the phenomena associated with it is called as sand dunes.

Hence, the most common cause of erosion in deserts is wind.
