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.
Answer:
Birds have a different mating season this evidence will go against the argument and suggest that the birds are actually different species. Generally, two factors seasonal and behavioral identifies the differences among the species. Species generally interbred among the same population of species according to the season and hence they loose mating opportunities. Although being sexually compatible they do not interbreed. Behaviorally, a biological clock in species naturally sets breeding cycle according to the resources availability, suitable nesting sites and mating opportunities. Different species have different seasonal requirements to accomplish this.
Answer:
B
Explanation:
Start by making a punnet square with the female’s genotype on top and the male’s along the left side. Because the traits are independent of one another, you have to put all possibilities for what the mother and the father can give to the offspring:
ST St sT st
ST SSTT SsTt SsTT SsTt
St SSTt SStt SsTt Sstt
sT SsTT SsTt ssTT ssTt
st SsTt Sstt ssTt sstt
Now for a leopard offspring to be sassy, their genotype would need to be ss because the S gene is dominant over s. Following that same logic, a timely offspring can have the genotype TT or Tt. Now we look back to the punnet square to see which squares match a sassy and timely offspring. These will be marked by a * next to it:
ST St sT st
ST SSTT SsTt SsTT SsTt
St SSTt SStt SsTt Sstt
sT SsTT SsTt ssTT* ssTt*
st SsTt Sstt ssTt* sstt
So the probability of having a sassy and timely offspring would be 3 out of a total of 16 squares. Convert that to a percentage and voila, you have your answer.
3/16 = 0.1875 x 100 = 18.75%
Meiosis<span> has </span>two<span> rounds of genetic separation and cellular division while </span>mitosis<span>only has one of each. In </span>meiosis<span> homologous chromosomes separate leading to daughter cells that are not genetically identical. In </span>mitosis<span> the daughter cells are identical to the parent as well as to each other.</span>
Its important because if not there could be an entire scarcity of things to eat and live off of so tech. the entire earth would not survive
