Small, highly concentrated cell organelles that produce proteins are called <span>ribosomes. Ribosomes can be free-floating or attached to endoplasmic reticulum.</span>
Answer: Muscle fibers in bundles or fascicles.
Explanation:
Skeletal striated muscle is involved in dense unshaped connective tissue, the Epimysium. From the epimysium depart fine septa of connective tissue to the muscle, separating the bundles and constituting the perimysium, carrying blood vessels and lymphatics and nerves. Every muscle cell is involved in the basal lamina, reticular fibers and a small amount of connective tissue, which form the endomysium. It anchors muscle fibers between them and contains blood capillaries and axons.
Answer: DESERT
Explanation:
Adaptation can be defined as the modification in the form, structure, function and behaviour of organisms in a habitat which enables them to live successfully and reproduce.
Desert is one of the types of the world biomes that is characterized with little or no rain and to extreme temperatures. Organisms, which includes plants and animals, must show some level of adaptation to able to survive the harsh environment.
The type of PLANTS which can survive in desert environment are called the XEROPHYTES. They show the following adaptations:
--> The roots are well developed: they grow down to great depths and branch extensively in order to absorb water
--> they possess swollen stems which contains water storage cells.
--> they have reduced leaves, for example in cacti in the form of spines, which helps to reduce water loss through transpiration.
The type of animal that survive in desert environment spend the hot dry seasons in a sleep-like torpid state called aestivation. This is so in order to avoid the heat. Their body size is usually small and less bulky: greater surface area in relation to body volume, thus enhancing heat loss from the body.
Organisms that live in the _________ must be adapted to little or no rain and to extreme temperatures.
Answer:
D- Phylogenetic Tree
Explanation:
It's in the definition of the word, no real explanation.
Answer: B. Neurotransmitters; C. Enzyme components; E. Hormones
Explanation: Aminoacids have a variety of functions because they can create proteins. These long and complex molecules perform important roles in different biological processes: they are responsible for the formation of enzymes and hormones. In neurotransmitters, the glutamate appears to be related to functions of the brain, like learning and memory. Other functions of the aminoacids are regeneration of muscular cells, have a role in imunology, growth of tissue, production of collagen and others.
