Answer:
The friend is wrong. This chemical equation supports the Law of Conservation of Matter. The reactants are the same amount as the products.
Explanation:
In both sides of the equation, there is 1 Ca, 1 C, and 3 O. This means that this equation follows the Law of Conservation of Matter.
A thanks and/or good rating would be greatly appreciated :D
Answer:
The correct order is:
#3 - will be first
#1 -will be second
#4- will be third
#2 - will be fourth
Explanation:
The third image shows the cell in interphase or early prophase as chromosomes are present in the nucleus of the cell which is dense due to genetic material. The first image shows the metaphase the second stage of mitosis where chromosome are lined up at the metaphase plate and each sister chromatid is joined to a spindle fiber of the equator.
The fourth image given showing anaphase in which chromosome split into two each towards the opposite side of the plate. Due to spindle fiber cell initiates to elongate. The second image showing two daughter cells after cytokinesis which is the separation of cell into two different entities
Answer:
The radial symmetry animals get information through their receptor cells and neurons present all over their body.
Explanation:
Radial symmetry animals can be cut in different directions. The central axis separates it into 2 equal halves and again it can be cut into 4 directions.
e.g. Hydra, sea urchin, starfish, etc
They are invertebrates have sense organs, but these sense organs are not well defined. Each symmetry of the body has sense organs. These radial symmetry organisms have oral and aboral parts.
Sea urchins, starfishes, Hydra are light sensitive. They possess photoreceptor cells in their epithelial linings. Starfishes also sensitive to touch, light, and temperature. Their spines and tube feet have motor nerves, which control their movement.
Eyespots in starfishes also help in detecting objects. It is composed of epithelial cells and responds to light. They lack a brain but have a complex nervous system. This nervous system consists of a sensory nerve and motor nerve. It spreads all over the body. Hence starfishes can react according to the stimuli.
