Plates at our planet's surface move because of the intense heat in the earth's core that causes molten rock in the mantel layer to move.It moves in a pattern called a convection cell forms when warm material rises,cools,and eventually sink down.

Answer:

See explanation

Explanation:

Taxonomy actually means “arrangement law”. It is the branch of biology that deals with the classification of organisms.

The taxonomic classification system was invented by Carl Linnaeus. It is a hierarchical model of classifying living organisms based on shared characteristics.

Dogs are referred to as 'man's best friend' partly owing to some level of taxonomic relationship between the two species. Dogs and man belong to a class of vertebrates known as mammals- one of the shared characteristics of mammals is that they give birth to their young ones alive.

The taxonomic classification of man is:

Domain: Eukaryote - Kingdom - Animalia Phylum - Chordata Subphylum - Vertebrata Class - Mammalia Order - Primates Family - Hominidae Genus - Homo Species - sapiens.

The taxonomic classification of dog is:

Domain: Eukaryote - Kingdom - Animalia Phylum - Chordata Subphylum - Vertebrata Class - Mammalia Order - Carnivora Family - Canidae Genus - Canis Species - lupus familiaris

Please help me!
Artemon [7]

Answer and explanation:

To address this question, we could design an experiment where the effect of soil and gravel can be tested independently. One approach is to test this via <u>Completely Random Design (CRD)</u>. Here, the <u>treatments would be assigned to experimental units completely at random</u> and each treatment will be tested in <u>replication</u> (e.g. triplicates).

The treatment levels would be (1) <u>Grass growing in the soil (triplicates)</u> and (2) <u>grass growing in the gravel (triplicates)</u>. There will be total 6 experimental units and they will be placed randomly. The growth parameters of grass would be then tested after growing for a certain period of time, let's say 90 days.

After this period, the <u>grass will be harvested</u> and the <u>biomass, root length and shoot length</u> will be measured. Because each treatment has three replicate, we will have a clear estimation of soil and gravel on plant growth. The standard deviation would help estimate the effect of natural variations in different treatments. However, they would be consistent because of same environment given for the growth.

The <u>independent variables</u> would be "<u>soil and gravel</u>" and <u>dependent</u> variables would be "<u>growth parameters of the grass (plant root and shoot length and biomass)</u>".

How do mutations increase genetic diversity in populations?

Flow of individuals in and out of a population introduces new alleles and increase genetic variation within that population. Mutations: changes to an organisms DNA that create diversity within a population by introducing new alleles.
