Answer:
Convection happens when particles with a great deal of warmth vitality in a fluid or gas move and replace particles with less warmth vitality.
Lighter (less thick), warm material ascents while heavier (progressively thick) cool material sinks. It is this development that makes course examples known as convection flows in the environment, in water, and in the mantle of Earth.
Huge amount of pressure and heat inside the earth causes the hot magma to stream in convection ebbs and flows. These flows cause the development of the structural plates that make up the world's outside.
Plates at our planet's surface move in view of the extreme warmth in the Earth's center that causes liquid shake in the mantle layer to move.
It moves in an example considered a convection cell that structures when warm material ascents, cools, and in the long run sink down. As the chilled material sinks off, it is warmed and rises once more.
Explanation:
In order to work as an environmental scientist.
Answer:
You need to use the scientific method and knowledge of the environment in order to work as an environmental scientist.
Explanation:
An environmental scientist should have an excellent knowledge about the systems of the environments and scientific methods. If a scientist is thorough about his understandings of the environment, he will be able to recognize any changes in the environment immediately and formulate the necessary reasons for the changes by using the scientific method of research. By using the scientific method of research, a scientist is able to learn about the various phenomenon occurring in the environment.
B) environmental conditions
C) predator-prey relationships
D) chromosomes and genes
Answer: D) chromosomes and genes
Chromosomes are long thread like structures which are found inside the nucleus of the living organisms. These chromosomes consists of small segment units called as genes. The genes control the genetic information which when expresses result in the production of specialized functional proteins. The gene is a hereditary material which is passed from the parents to the offsprings after reproduction. The expression of genes in the new organisms results in the expression of characters which were found to be similar in both parents and offsprings but some changes occur due genetic variation. Therefore, organisms exhibit anatomical similarities in features due to chromosomes and genes.
Chromosomes and genes determines the similarities in anatomical features among organisms. The correct option is D.
Thus, Chromosomes, which resemble lengthy threads, are found inside the nucleus of living things. The little segment units that make up these chromosomes are known as genes.
The genes regulate the genetic material, which, when expressed, leads to the creation of certain, useful proteins. The gene is a genetic component that, during reproduction, is transferred from parents to children.
Characters that were determined to be comparable in both parents and children are expressed by genes in new creatures, however some modifications take place owing to genetic diversity. The correct option is D.
