Answer:
Pseudopodia are temporary and cytoplasm-filled parts of the cell membrane that are able to change their form in order to move.
Explanation:
Pseudopodia are temporary and cytoplasm-filled parts of the cell membrane that are able to change their form in order to move. They are used in some eukaryotic cells to move around or to eat. Most cells that do this are called amoeboids. The amoeba is a common example. ... Pseudopods can also capture prey by phagocytosis.
B. a form of gene is the correct answer
Answer:
Stomata
Explanation:
Photosynthesis is a unique phenomenon which occurs in the Chloroplast of plant cells. It is the way they synthesize their food in form of glucose. However, like every metabolic reaction, photosynthesis requires certain reactants and products.
Photosynthesis combines carbondioxide (CO2) gas and water (H2O) in the presence of sunlight to produce Glucose (C6H12O6) and oxygen gas (O2). The gaseous components of this metabolic activity enters (C02) and leaves (O2) the plant via a structure in the leaves called STOMATA.
STOMATA is a pore found in the epidermis layer of plant leaves that aids in the exchange of gases i.e. carbondioxide in, oxygen out during Photosynthesis.

Answer:
The answer is 'D'- Their arm bones have the same structure, but not function. These are homologous structures.
Explanation:
Homologous structures are those which share a basic common structure but perform different function. The hand of a human performs functions like <em>writing, cutting, washing, chopping</em> etc. The wings of a bat are used for the purpose of <em>flying</em>.
Also, <em>a dolphin's flippers, a bird's wing, a cat's leg</em> are all <u>homologous structures</u>. The structures which are homologous have the following features:
- They share a <em>common origin</em>
- Their <em>anatomy</em> is similar
- They have a <em>similar pattern of development</em>.
