Answer:
Radial symmetry
Explanation:
One of the most prominent features of echinoderms is their radial symmetry. This means that if we divide the organism around any main axis it should be divided in two exactly similar halves across any plane passing through the body. This is because the mouth is surrounded by a central disk that contain specific structures called podia that radiate outwards and gives the radial symmetry to organism.
For example: The body of ctenophores, echinoderm, sea-anemone and many sponges have radial symmetry. Some echinoderms that have radial symmetry include sea urchin, Sea cucumber, bitter star etc.

Answer:
RNA
Explanation:
Transcription is the first process of protein synthesis and it involves copying the information encoded in the genetic material (DNA) to a RNA molecule. It involves making a complementary strand of mRNA from a DNA template.
The process of transcription commences when an enzyme called RNA polymerase binds to the promoter region of a gene on the DNA, signalling the unwinding of its double-stranded structure. The RNA polymerase then adds nucleotides to the growing RNA molecule, complementary to the ones it reads on the DNA. The RNA synthesized during transcription is called messenger RNA (mRNA).
The mRNA is then used as a template for amino acids synthesis during translation.

Nowadays, many people across the world are reducing the consumption of dietary fats to avoid the onset of chronic heart and kidney diseases. However, a low-fat diet is not always a great diet for health.
The fact is that all fats do not affect the body in same way. The refined and processed fats found in restaurant and packaged foods cannot be good to health. But natural fats have very healthy effects on us.
Fats perform many important functions in our body. They play important role in regulation of body temperature, weight management, nutrient absorption, boosting immune function,insulation of body organs and maintenance of healthy hair and nails.
A diet poor in fats can cause serious issues for the health of an individual, such as:
- Poor Brain Function
- Compromised Heart Health
- Hormone Imbalances (Including Sex Hormones Testosterone and Estrogen)
- Weight Gain and Overeating
- Higher Risk of Insulin Resistance and Diabetes
- Higher Risk for Depression and Anxiety
- Gut-Related Problems
Therefore, a moderate intake of fats (>15 % of energy) is important to maintain a good health of the individual.
Answer:
they can learn how protein sequences affect genes
Explanation:
Because they're are different kinds of genes and different kinds of proteins in each organism
