The thermosphere is the hottest layer of the Earth.
Answer:
d. different traits
Explanation:
Human cell are diploid (with the exception of gametes) which means that they have two sets of chromosomes: one inherited from mother and another inherited from father (23 chromosomes in each set, total of 46 chromosomes per cell). Those chromosomes in pair are called homologous chromosomes, they are the same in size and shape, contain the same genes but code for different traits.
Prokaryotic cells do not contain a nucleus or any other membrane-bound organelle. Eukaryotic cells contain membrane-bound organelles, including a nucleus. So I belive the answer is A :P Hope it helps
<h2>Part 1 Answer</h2>
<u>Limestone is a type of</u><u> sedimentary rock </u>
<h2>Explanation:</h2>
Limestone is a type of sedimentary rock which is composed mainly of skeletal parts of organisms living in water such as coral, forams and molluscs. The major materials of limestone are the minerals such as calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO3). Limestone can turn into the metamorphic rock called marble if the right conditions occur.
<h2>Part 2 Answer:</h2>
<u>Over time limestone </u><u>can be deformed and crystallized</u>
<h2>Explanation:</h2>
Limestone and chalk are mostly made up of calcium carbonate. When acidic rainwater falls on limestone or chalk, these rocks may react with the rainwater, causing the rock to be weathered. With the passage of time if limestone has been squeezed and reshaped by temperature and pressure, its structure and composition changes to form a recrystallised limestone which is called marble.
