1-A mineral is a naturally occurring inorganic element or compound having an orderly internal structure and characteristic chemical composition, crystal form, and physical properties. ... A rock is an aggregate of one or more minerals, or a body of undifferentiated mineral matter.
2-Part of Hall of Planet Earth. There are three kinds of rock: igneous, sedimentary, and metamorphic.
3-Intrusive rocks are formed from magma that cools and solidifies within the crust of the planet. When lava comes out of a volcano and solidifies into extrusive igneous rock, also called volcanic, the rock cools very quickly.
4-Igneous rocks are formed from lava or magma. Magma is molten rock that is underground and lava is molten rock that erupts out on the surface. The two main types of igneous rocks are plutonic rocks and volcanic rocks. Plutonic rocks are formed when magma cools and solidifies underground.

14. Round off all numbers in the ratios to whole numbers. What ratio do you get?
Answer:
3:1, 2.95:1, 2.82:1, 2.95:1, 3.14:1 AND 1.84:1.
Explanation:
The ratio between yellow and green seed colour is 3: 1. The higher ratio of yellow colour occur because the yellow colour is dominant as compared to green seed colour.
The ratio between round and wrinkled seed shape is 2.95 : 1.
The ratio between green and yellow pod colour is 2.82 : 1.
The ratio between smooth and bumpy pod shape is 2.95 :1.
The ratio between along stem and at the tip of flower position is 3.14 : 1.
The ratio between tall and short plant height is 2.84 : 1.
Look at the graph...What is the optimal temperature for this enzyme?
A. 60 degrees C
B. 45 degrees C
C. 15 degrees C
D. 35 degrees C
Answer:
B: 45 degrees C
Explanation:
However, above 40-45 degrees Celsius, enzymes are usually denatured and can no longer catalyse the reaction, because the hydrogen bonds are broken, so the enzyme permanently loses its shape. The temperature at which the reaction rate is fastest is the optimum temperature.
As per the graph, the optimum temperature for the enzyme is 45 degree Celsius. The correct option is C.
What is optimum temperature?The temperature at which the enzyme exhibits the greatest activity is referred to as the optimum temperature.
Enzyme activity decreases as the temperature rises or falls. It can even become inactive at times. It is equivalent to the body temperature of a warm-blooded animal.
The kinetic energy in the substrate and enzyme molecules is optimal for the maximum number of collisions at the optimal temperature.
At high temperatures, the enzyme's shape changes, and it no longer complements its specific substrate.
It is the temperature at which the enzyme's reaction rate is fastest. It will be the point on the graph where the line reaches a peak at 45 degrees Celsius.
Thus, the correct option is C.

What is DNA polymerase?
Answer:
A DNA polymerase is a member of a family of enzymes that catalyze the synthesis of DNA molecules from nucleoside triphosphates, the molecular precursors of DNA. These enzymes are essential for DNA replication and usually work in groups to create two identical DNA duplexes from a single original DNA duplex

Variations between organisms are caused by differences in
Answer:
Genetic variation occurs because beneficial traits exist in a collection of genes, and gene flow makes these traits more prevalent in populations.
Further explanation
Genetic diversity is a level of biodiversity that refers to the total amount of genetic variation in the whole species that inhabits some or all of the earth's surface that can be inhabited.
Genetic diversity uses several simple measurements:
Gene diversity is the proportion of polymorphic loci throughout the genome.
Heterozygosity is the average number of individuals with polymorphic loci.
Alleles per locus, also used to demonstrate variability.

Answer:
Terrestrial ecosystems are known for their diversity; they are grouped into large categories called biomes. Grouping these ecosystems into just a few biome categories obscures the great diversity of the individual ecosystems within them. For example, there is great variation in desert vegetation: the saguaro cacti and other plant life in the Sonoran Desert, in the United States, are relatively abundant compared to the desolate rocky desert of Boa Vista, an island off the coast of Western Africa

Which of the following describes the result of independent
assortment and crossing over during meiosis?
A: it creates genetic differences in sperm and egg
B: it produces higher quantities of sperm and egg
C: it produces individuals that are very similar to their parents
D: it makes fertilization go smoothly
Answer:
A.)
Explanation:
Independent assortment and crossing over is important because it creates genetic variation between gametes. This immediately eliminates (C) and in no way does crossing over or independent assortment cause more gametes to be produced so cross out (B). Only (A) and (D) is left, while both answers makes sense, (A) is the better one.
Meiosis takes place in the germ cells and give rise to haploid gametes. Due to the events including crossing over and independent assortment, it causes genetic differences in sperm and egg, i.e., option A.
What is crossing over?Chromosomal crossover also referred as crossing over, represents the exchange of genetic material during gamete formation,
It occurs between two non-sister chromatids of homologous chromosomes that results in recombinant chromosomes.
This creates genetic differences in the sperms and eggs.
Thus, the correct option is A.
