Answer:
D.
Both the femur and humerus bone have what's called 'spongy bone' inside them and hollow spaces full of yellow and red bone marrow. Additionally, both bones do not attach to the axial skeleton but rather attach to the pelvic or hip bones; while they are both strong bones, they are not made of only compact bone but are made of 'spongy bone' inside them. Lastly, they do not protect any organs but rather allow for movement. D, They both have hollow spaces filled with bone-generating cells, is the best answer in this case
Explanation:
I think the polymers are the hydrocarbons.
If this helped please mark me as brainliest.
Its definitely not A, nor is it D because food webs and food chains can be either land or aquatic animals. i think its B because a food chain goes up and a food web includes more organisms
Meiosis produces haploid cells rather than diploid cells because they need to make gametes (egg, and sperm cell) for reproduction.
Answer:
The Markonikov's rule determines where to add a nucleotide in the reaction
Explanation:
In organic chemistry, the organic carbonyl reactions are governed by a set of rules. One of them is the Markovnikov's rule. Basically, the rule determines where the addition of the nucleophile and a hydrogen will take place in a chemical reaction involving alkene addition. In the reaction principles, there are rules to follow based on the syn and anti addition. This refers to which side the two groups will face. they add to the same side an called the syn. When its opposite side, then its anti.
