Arteries need to be thick, muscular and elastic IN ORDER TO WITHSTAND THE PRESSURE OF THE BLOOD THAT IS BEING PUMPED BY THE HEART.
The walls of the arteries are thicker and more muscular than that of veins because of the work that they perform. The arteries have thick and muscular walls, which help them to withstand and absorb the pressure waves that are generated as a result of blood pumping from the heart. The elasticity of the arteries help them to generate appropriate pressure for supporting blood flow.
The answer is nonvascular plants.
The plants that are similar to algae are called nonvascular plants. They are the plants small plants with the absence of vascular system. They do not have roots. They have small hair likes that insert to substrate to keep the plants in place instead of roots. These are called rhizoids.
b. The sun
c. Terrestrial planets
d. Solar winds
Answer:
a. Material from previous stars
Explanation:
Solar nebula was a molecular cloud, composed of dust and gases from which the sun and planets were born. The solar nebula material came from the material from the previous stars. When a star dies, it expels out most of its mass and from this material, nebula is formed from which new stars and planets form.
Solar wind is composed of high speed charged particles emitting out from the sun.
Terrestrial planets have rocky surface.
Answer:
Carbohydrate Metabolism.
Explanation:
Carbohydrate metabolism refers to the biochemical processes which are accountable for metabolic formation, breaking down of carbohydrates and conversion of carbohydrates in the body of living organisms. I'm plants, carbohydrates are combined from carbon dioxide and water using photosynthesis, which store energy from sunlight. Animals use cellular respiration to break down stored energy in plants which they have consumed, for the availability of energy to cells. I'm human, carbohydrates are broken down to glucose, fructose and galactose through digestion. In aerobic respiration, glucose and oxygen undergo metabolism to release energy which carbon dioxide and water are secondary products.
B. the alkali metals and the transition metals.
C. the actinide series and the alkaline earth metals.
D. the lanthanide series and the actinide series.
Answer: D. the lanthanide series and the actinide series.

Answer;
-5-carbon sugar
Explanation;
-The basic repeating unit of nucleic acids are known as nucleotides. There are two types of nucleic acids, namely RNA and DNA.
-A nucleotide consists of three distinct chemical groups, a 5-carbon sugar (ribose or deoxyribose), a nitrogen-rich base - (cytosine (C), guanine (G), adenine (A), thymine (T) in DNA or uracil (U) instead of T (in RNA), and phosphate.
Nucleotides consist of a phosphate group, a nitrogenous base, and a 5-carbon sugar.
Nucleotides, the building blocks of nucleic acids, consist of a phosphate group, a nitrogenous base, and a 5-carbon sugar. The 5-carbon sugar is called a pentose sugar. In DNA, the 5-carbon sugar is deoxyribose, while in RNA, it is ribose.
