Answer:
Hi, you probably already submitted but I believe it will be A: All living things use energy to carry out essential life functions.
B. Not all living things have brains. For example, plants are living and they don't have brains. Neither do unicellular organisms.
C. Not all living things have stomachs. Plants eat, but not with a stomach. They absorb nutrients.
D. Phagocytosis is ingestion. Not all living things undergo it. Again, going back to the plants example, they do not, so therefore it isn't all living things.
Although cells are diverse, all cells have certain parts in common. The parts include a plasma membrane, cytoplasm, ribosomes, and DNA. The plasma membrane (also called the cell membrane) is a thin coat of lipids that surrounds a cell.
Hope it helps ^^
Answer:
We get oxygen from the air i.e. atmosphere. Green plants release oxygen in the atmosphere as a byproduct of photosynthesis. Respiratory system is responsible for obtaining oxygen from the environment. Circulatory system on other hand helps in delivering this oxygen to different cells of the body with the help of blood.
We get nutrients from the food that we eat. Digestive system breaks down all the complex compounds (such as polysaccharides, polypeptides, fats etc) into simpler elements which are easy to absorb.
produced as a waste product by the cells is carried by the blood to alveoli in the lungs where it gets diffused out and come out of the body as a part of exhale air. Hence, circulatory system helps in he transportation of from cells to the lungs and respiratory system helps in expelling it out from the lungs to the outside environment.
Solid wastes are mainly excreted out of the body from anus which is a part of digestive system. On the other hand, liquid waste (urine) is excreted out of the body with the help of urethra which is the part of excretory system. In addition, excess salts and water can also excrete out of the body through skin.
Muscles and bones together help us in our locomotion. Nervous system is important for proper functioning of bones and muscles.
Meiosis is the type of cell division used to produce haploid cells or gametes from a diploid parent cell. Hence, it is used in reproduction system to produce sperm in males and eggs in females.
Answer:
What inhibits rainwater seepage into the ground is the concrete floor.
Explanation:
In general, water from rain is usually absorbed by the ground, due to its relative porosity. Concrete is solid and non-porous, forming an impermeable layer that prevents water from passing through it.
Concrete comes from a mixture of cement, sand and water, forming a malleable mass that hardens when dry. It is used for the manufacture of floors and buildings, and is characterized by its relative impermeability.
Other options are not correct because:
<em> Playground, grass lawn and forest land allow the absorption of water from rain.</em>
<span>Fish that can tolerate a wide range of salinity at some phase in their life-cycle are called euryhaline species. These fish, which include salmon, eels, red drum, striped bass and flounder, can live or survive in wide ranges of salinity, varying from fresh to brackish to marine waters.</span>
