Let's use process of elimination to answer this question!
D is wrong, and we know this because of the names of DNA and RNA. The D in DNA stands for deoxyribose, and the R in RNA stands for ribose. These are the types of sugars in each nucleic acid. Therefore, they don't both contain a ribose sugar.
C is wrong, and this is because RNA does not contain thymine, but uracil instead.
B is wrong, and we know this because we know that RNA is composed of only one strand, and therefore it is not composed of multiple stands (plural).
Therefore, A must be right. We can confirm this, because we know that polymers are large molecules consisting of repeated subunits. DNA and RNA are both polymers consisting of nucleotides.<span />
Answer:
a. the segmented body plan of the annelids
Explanation:
- lophotrochozoan is a taxonomy of animals that includes annelids, bryozoans, and brachiopods.
- This taxonomy of creatures was defined in 1995 as the last ancestor of the taxa of worms, mollusks, and annelids. Their classical definition depends on the topology of the spiral tree of life.
- Annelids have a segmented body part wherein the external morphological features are repeated in every body segment. It allows the animal to become bigger and makes their movement more fat and efficient.
Answer:
Joan Walks
miles farther than maria
Explanation:
Given:
Distance walked by Nicole = 1. 11/12 miles
Distance walked by Tasha= 2. 1/12 miles
Distance walked by Maria = 1. 7 /12 miles
Distance walked by Joan = 2. 2/12 miles
To find:
How much farther Joan walks to school than Maria = ?
Solution:
We can find the distance that Joan walk more than maria by subtraction
Joan distance - maria distance
here the distance are given in mixed fraction , so lets covert them into fraction and perform subtraction

Acid rain is man made and there is more types of acid. Normal rainwater is dissolving Carbon Dioxide as it falls through the sky. When a volcano erupts actually slightly acidic with a pH of just over 6. This is due to the rain it releases gases such as Sulphur Dioxide into the air which makes the rainwater more acidic with a pH of about 4. Air pollution caused by man also contributes <span>to the acid rain.</span>
