Answer:
Think about it. Worms move with MUSCLES. So the first answer is None.
The appendage of a roundworm is not present.
How do you think worms turn and move? They are segmented. The symmetry of a worm is Bilateral.
Explanation:
I'm doing the assignment myself. Look up the answers and use common logic.
Answer: The base pair rule for RNA is that adenine pairs with uracil, thymine pairs with adenine and cytosine pairs with guanine.
Explanation: RNA contains adenine, uracil, cytosine and guanine while DNA contains adenine, thymine, cytosine and guanine. Thymine is not found in RNA while uracil is not found in DNA. In RNA base pairing, Watson and Crick proposed a rule that wherever adenine is found in DNA, Uracil occurs in the complementary RNA strand, wherever thymine is found in the DNA strand, adenine is found in the complementary RNA strand and wherever guanine occurs in the DNA strand, cytosine is found in the complementary RNA strand.
Pigment molecules capturing photons in the chloroplast are organized in distinct structures called photosystems.
Photosynthetic pigments, which include chlorophyll a, chlorophyll b, and carotenoids, are light-harvesting molecules found in chloroplast thylakoid membranes. As previously stated, pigments and proteins are organized into complexes known as photosystems.
Photosystems are functional units for photosynthesis that are defined by specific pigment organization and association patterns. Their work is the absorption and transfer of light energy, which implies electron transfer. Photosystems are physically found in thylakoid membranes.
Chloroplasts are chlorophyll-containing organelles found in plant cells; they are essential for life on Earth because photosynthesis occurs in chloroplasts. Proplastids give rise to chloroplasts, as do chromoplasts, leucoplasts, and other plastids. Light energy absorption and conversion into biological energy

Women are being advised to sleep on their side in the last three months of pregnancy, women in their third trimester are encouraged not to sleep on their backs. When they sleep on their back, the chances of the heavy uterus can reduce blood flow to the uterus and fetus, which can result in a stillbirth. Also, women are encouraged to sleep on their left side, as this is considered the best choice because the uterus naturally alternates to the right during pregnancy and left-sided lying will bring it more to the center and improve blood flow.
To help her sleep, a pillow can be placed between her legs or a long body pillow to support the back are often helpful. When a pillow is placed direct at her back and front, it helps support her body, resulting in a more comfortable position for sleep.
The major reason why she is having lightheadedness and dizziness when she lies on her back is that the weight of her uterus can compress a major blood vessel, called the vena cava, this then disrupts blood flow to the baby, leaving her nauseated, dizzy, and short of breath.
