Explanation: The green algae population will increase because if the crustaceans are killed, there is no consumption of algae hence resulting in increased levels of algae.
After that the blue gill fish that is the consumer of crustaceans will also be affected, their numbers will start to reduce with time and they might die off unless they move to another habitat so the option "D" is wrong
The term ''tissue'' refers to a group of similar cells. Being a combination of equal cells, a tissue has the same function in any part of the body.
The four types of tissues are:
. The epithelial tissue
. The connective tissue
. Muscle tissue
. The nervous tissue
. The epithelial tissue serves as a cover, among these are the skin and the lining of several ducts inside the body. It is divided into two general classifications: Simple Epithelium and Stratified Epithelium.
. The connective tissue supports and joins other tissues such as bone, blood and lymphatic as well as adipose tissue and reticular tissue.
. Muscle tissue consists of striated or voluntary muscles that move the skeleton and smooth muscle, such as the one that surrounds the stomach. It is divided into three types: Skeletal Muscle Tissue, Cardiac Muscle Tissue and Smooth Muscle Tissue.
. Nervous tissue is formed by nerve cells or neurons and serves to carry messages to and from various parts of the body. This tissue is present mostly in the brains and spinal cord. It has two types of tissue: The Nerve Cell and the Neuroglia.
Question:- what is the net charge of the structure in the figure below?
A. 1-
B. 1+
C. 2+
D. 2-
Answer
there are 3 protons (+ve charge) and 2 electrons (-ve charges )
so net charge is positive one
Answer:
Consider all forces acting in the body. Resolved them in x-y-z axes. On every axis, take one direction to be positive and subtract the force of opposite direction from that force.
