Answer:
squamous epithelium consists of a single layer of flat cells. It is found in lungs,heart and blood vessels.It allows the movement of materials across it.
stratified epithelium has many layer of flat cells.It is present in lining of oesophagus and mouth and also over the skin
Answer: i guess it is the option (c) because Pesticides are poisonous and, unfortunately, they can harm more than just the “pests” at which they are targeted. They are toxic, and exposure to pesticides can cause a number of health effects. They are linked to a range of serious illnesses and diseases from respiratory problems to cancer.
Explanation:
<span>The lining of the digestive tract is an example of "Epithelial Tissues"
In short, Your Answer would be: "False"

Answer:
each of your kidney is made up of about a millions filtering units called nephron.
- each nephrons are include the filter called the glomerules and a tubule.
- the nephron uses four mechanism to convert blood into urine.
- filteration
- excreation
- secration
- reabsorption
Explanation:
a structure that contain vascular loop of the glomerules at at the sight of blood filtrationand a tubular segment that reabsorption and excreation solutes and connect to the collecting duct system..

Explanation:
A)Image A represents a peptide hormone that interacts with a receptor, and image B represents a steroid hormone that interacts with the cell’s DNA
The endocrine system involves chemical signalling via the secretion of molecules called hormones into extracellular fluid.
- Steroid hormones are lipophilic, and readily diffuse across cell membranes. They bind to receptors in the interior of the cell to form a complex which regulates gene expression.
- Peptide hormones however,are hydrophilic, and thus cannot readily diffuse across the membrane. They remain outside the cell, binding to receptors which then activate secondary messenger signalling and a subsequent cellular response.
Further Explanation:
Hormones bind to chemical receptors in order to cause specific changes in target cells, these lead to changes in the body's internal environment called homeostasis. It includes the thyroid, parathyroid, pituitary, pineal and adrenal glands along with other regions.
The bone, adipose tissue, heart, pancreas and liver are a few of the regions of the body which show endocrine function. The brain, or control center functions to receive and process the information from the receptor. Effectors receive the control center's command and elicits a response in the form of a feedback loop, that may oppose or enhance the stimulus.
Cells in a multicellular organism become specialized for particular tasks and communicate with one another in order to maintain homeostasis. Within the human body these are known as hormone cascades, where several complex steps occur- the tissues signal to one another with the use of hormones released by the endocrine system. The regulation (increase and decrease) of these secretions is achieved by negative feedback loops, where the release of certain substances during a cascade in turn halts the secretion of hormones at earlier stages.
