Answer:
Explanation:
Mutations are alterations in the genetic code that may occur due to environmental or chemical mutagens. Mutagens, are substances or agents that induce changes in the genetic code.
Photosynthesis is a complex biochemical process; plants convert solar energy into chemical energy as sugars like the polysaccharide glucose. They also use inorganic carbon from along with .
Plants photosynthesize in their leaves- these organs contain tissues for intake, along with the chloroplasts and mitochondria, the sites of photosynthesis and respiration. If the number of leaves are reduced, this reduces the amount of tissue capable of carrying out this essential process, limiting the plant's chance for meeting its energetic needs, and thus survival.

b.tentacles
c. specialized cells
d. bilateral symmetry
Answer:
c. specialised cells
Explanation:
Sponges are invertebrates that belong to phylum Porifera. Most of them live in marine environment. They do not have true tissues or organs but specialised cells that perform specific functions for example porocytes, amoebocytes, pinacocytes and choanocytes. Porocytes control the water amount entering inside the sponge pores and choanocytes control the water movement inside the sponge body.
Sponges consume food via phagocytosis. They reproduce both asexually and sexually. They are sessile i.e. immobile.
Sponges have specialized cells that perform specific functions like filtering food and excreting waste. They do not have a coelom, tentacles, or bilateral symmetry.
Sponges have specialized cells. These cells are responsible for the various functions of sponges, such as filtering their food and excreting waste. Some examples of specialized cells in sponges are collar cells, which line the inside of the sponge and generate water flow, and amoebocytes, which transport nutrients throughout the sponge. Sponges do not have a coelom, tentacles, or bilateral symmetry.

Answer: Temporarily separated
Explanation:
The species that once lived together and now are separated due to the time can be termed as temporarily separated.
This happens when two similar species live together but with time they get separated and theirs habits change.
Here, one of the bat species feed on animals during the daytime and other one feeds at night.
The statement for the transport of water and minerals from roots to plant by phloem is false.
The transport of food, water, and minerals from the roots to the leaves is mediated by the vascular tissues xylem and phloem in the plants.
The water and minerals are absorbed by the plant's roots from the soil, and are transported from the roots to the stem and leaves by the process of osmosis.
The transport of food in the plants is carried by phloem tissues, and the transport of water and minerals is carried by the xylem tissues.
Thus, the given statement is false.
