Answer:
D. they are unicellular
Explanation:
unicellular organisms are not part of the kingdom animalia .Animalia consists of aves(birds),amphibians,reptiles,mammals and so on and all these organisms are multicellular that is having more than one cell.
Breathing is the process of moving air out and in the lungs and Respiration is the movement of oxygen from the outside environment to the cells within tissues, and the removal of carbon dioxide in the opposite direction.
Answer:
The lungs
Explanation:
The lungs in your body get filled up with air when you inhale. There are blood vessels around the alveoli in your lungs (which are tiny air sacs that hold the air). The blood vessels absorb the oxygen in a process called diffusion where gas diffuses through the one cell thick wall of the alveoli into the blood vessels. The circulatory system then pumps the blood around your body to the cells that need the oxygen.
Phage therapy or viral phage therapy is the therapeutic use of bacteriophages to treat pathogenic bacterial infections. Phage therapy has many potential applications in human medicine as well as dentistry, veterinary science, and agriculture. If the target host of a phage therapy treatment is not an animal, the term "biocontrol" (as in phage-mediated biocontrol of bacteria) is usually employed, rather than "phage therapy".
Bacteriophages are much more specific than antibiotics. They are typically harmless not only to the host organism, but also to other beneficial bacteria, such as the gut flora, reducing the chances of opportunistic infections.They have a high therapeutic index, that is, phage therapy would be expected to give rise to few side effects. Because phages replicate in vivo (in cells of living organism), a smaller effective dose can be used.
The biotic factors can be defined as those living elements of an ecosystem that affects the other members of the ecosystem and also shapes it. The examples include animals and plants. The abiotic factors can be defined as those elements which are non-living and have effect on the other components of the ecosystem. The examples include water, air, soil etc.
A rabbit having long ears in order to disperse heat is adapting to the abiotic factor, i.e. the heat.
The spines of cactus are an adaptation to another abiotic factor, water.
The bright red color of the petunia is to attract the hummingbirds for pollination. They are adapting to the biotic factor (hummingbird).
The blending ability of stick-bugs to hide in the trees is an adaptation to the biotic factor (predators).
The diving ability of the moth is an adaptation to the biotic factor bat, in order to escape predation.
The adaptation of the lizard to sun itself on the rock in order to stay warm is in response to an abiotic factor (heat).
