Vacuoles are storage organelles that are found in both animal and plant cells. They store food or any other forms of nutrients, they also store waste products so as to protect the contamination of the cell environment. These waste products are sent out of the cell via vacuoles. In plants the vacuoles are larger than in animals. The vacuole provides plant nourishment in the scarcity of water in the external environment hence, prevents the wilting of plants.

Answer:
Gram positive bacteria are more resistant than gram negative bacteria to antimicrobials that disrupt plasma membranes because they have cell wall that is made up of a thick layer of peptidologlycan that contain teichoic and lipoteichoic acid to peptidoglycan.
Explanation:
Gram positive bacteria are bacteria that have thick wall made up of peptidoglycan and have no lipid membrane while gram negative bacteria are bacteria that have thin cell wall composed of peptidoglycan with lipid membrane.
Gram positive bacteria is resistant to antibiotics because of their thick cell wall composed of peptidoglylcan which contain teichoic and lipoteichoic acid , this help strengthen the plasma membranes and make them not to be attached by antimicrobial compared to gram negative that lack this.
More than 90 percent of the weight of fat in foods and more than 95 percent of the stored fat in the human body are in the form of: triglycerides.
<h3>
What is triglycerides?</h3>
Among fats, triglycerides are one. They make up the majority of the fat in your body. They originate in food, particularly in the butter, oils, and other fats you consume. Additionally, extra calories provide triglycerides. You consume these calories, which your body does not immediately require. These extra calories are converted by your body into triglycerides and stored as fat. The triglycerides are released when your body requires energy. The triglycerides are transported to your tissues by VLDL cholesterol particles.
Your chance of developing heart conditions like coronary artery disease is increased if your triglyceride levels are high.
