B. lack vascular tissue. Mosses need to absorb water directly from the soil close to the ground because they don't have stems, roots, and leaves that plants use to absorb water .
This is called selective breeding
hope this helped!
Answer:
Characterstics of larva of silkworm on the basis of body structure is given :
1) The body of larva of silkworm consist of head, thorax and abdomen. The mouth part consist of pair of strong mandibles and a pair of lip.
2) There are three segments of thorax region. Each segment bears a pair of legs. The abdomen part is divided into ten segments. The third, fourth, fifth, sixth and ninth abdominal part produces abdominal appendages called false legs.
Answer: adenosine triphosphate (ATP) - the high energy chemical compound with three phosphate groups that provides energy for all other cell activities
endocytosis - when cells engulf or ingest substances
cellular respiration - chemical reactions in plants and animals that break down food molecules into energy (ATP)
movement of particles or molecules from higher concentration to lower concentration - diffusion
when cells expel or get rid of substances from within- exocytosis
a solution that has a higher salt concentration than the salt - hypertonic
the relatively constant state in the internal environment of an organism - homeostasis
Explanation:
Adenosine triphosphate or ATP is the energy currency that is required for providing energy for metabolic functions and activities in the body.
Endocytosis can be defined as the process through which a cell engulfs another cell or substances to get rid of them.
Cellular respiration can be defined as the process through which the food in the organisms is oxidized and broken into parts to release energy.
Diffusion involves the movement or transfer of gas, liquid, and solid particles from a region of higher to lower concentration without the requirement of semi-permeable membrane.
Exocytosis is a process in which the cell releases those substances that are required by the cell.
Hypertonic is a solution that has more solute concentration than solvent concentration.
Homeostasis is a tendency to maintain constancy in the internal environment of body in relation to changes occurring in the surrounding.
