Answer:
Chemical changes cause a substance to change into an entire substance with a new chemical formula. Chemical changes are also known as chemical reactions. The “ingredients” of a reaction are called reactants, and the end results are called products.
Explanation:
Carbon atoms got 4 surface electrons which makes them in the middle regarding the electrical surface charge and they can make a maximum relations of 4
<span>they both have two alleles
</span>they both express the dominant allele (aka the phenotype or physical traits of the allele). They are different in genotype though, which is their genetic make up because homozygous would be two dominant alleles and heterozygous is a combination of dominant and recessive allele. Homozygous recessive and heterozygous are completely different <span>though in genotype and phenotype.</span>
Answer:
club mosses
Explanation:
Microphyll is a type of plant leaf defined by the existence of a single non-branching rib. The present species that have microphiles have small and relatively simple leaves, associated with protosteal stems; however in the past there were representatives with microphiles up to one meter long. The most widely accepted theory about the origin of microfiles is that they evolved from lateral projections of the main axis.
Microphils are characteristic of club mosses, spike mosses, and quillworts leaves.
Fusion and gravity
Fusion and gravity keep the sun from blowing itself up. A large amount of energy is released by the
sun. Protons are fused together to form helium atoms due to the high heat and
pressure at the center of the sun. The Sun does not blow itself up from the
outer pressure of nuclear fusion in as much as the inner force of gravity
balances it.
