Answer:

What Is Blood and What Does It Do?

Blood is needed to keep us alive. It brings oxygen and nutrients to all the parts of the body so they can keep working. Blood carries carbon dioxide and other waste materials to the lungs, kidneys, and digestive system to be REMOVED from the body. Blood also fights infections, and carries hormones around the body.

Blood is made up of blood cells and plasma. Plasma (say: PLAZ-muh) is a yellowish fluid that has nutrients, proteins, hormones, and waste products. The different types of blood cells have different jobs.

What Are the Types of Blood Cells?

Red blood cells: Red blood cells (RBCs, also called erythrocytes; say: ih-RITH-ruh-sytes) are shaped like slightly indented, flattened disks. RBCs contain hemoglobin (say: HEE-muh-glow-bin), a protein that carries oxygen. Blood gets its bright red color when hemoglobin picks up oxygen in the lungs. As the blood travels through the body, the hemoglobin releases oxygen to the different body parts.

Each RBC lives for about 4 months. Each day, the body makes new RBCs to replace those that die or are lost from the body. RBCs are made in the inside part of bones called the bone marrow.

White blood cells: White blood cells (WBCs, also called leukocytes, say: LOO-kuh-sytes) are a key part of the immune system. The immune system helps the body defend itself against infection. Different types of WBCs fight germs, such as bacteria and viruses. Some types of WBCs make ANTIBODIES, which are special proteins that recognize foreign materials and help the body get RID of them.

There are several types of WBCs, and their life spans vary from hours to YEARS. New cells are constantly being formed — some in the bone marrow and some in other parts of the body such as the spleen, thymus, and lymph nodes.

Blood contains far fewer WBCs than red blood cells, although the body can increase WBC production to fight infection. The white blood cell count (the number of cells in a given amount of blood) in someone with an infection often is higher than usual because more WBCs are being made or are entering the bloodstream to battle the infection.

Platelets: Platelets (also called thrombocytes, say: THROM-buh-sytes) are tiny oval-shaped cells that help in the clotting process. When a blood vessel breaks, platelets gather in the area and help seal off the leak. Platelets WORK with proteins called clotting factors to control bleeding inside our bodies and on our skin.

Platelets survive only about 9 days in the bloodstream and are constantly being replaced by new platelets made by the bone marrow.

Answer:

Simple Permanent Tissues

These tissues are simple. They are made up of only one type of cell. Here, all the cells that MAKE up the tissue are similar and have the same structure, with the same type parts. Simple permanent tissues are again classified into three main TYPES. They are parenchyma, collenchyma, and sclerenchyma.

Parenchyma – The cells of this tissue are living, with thin cell walls. Cells can be oval or round in shape. They have a large central vacuole and a dense cytoplasm. The parenchyma tissue is located in the soft parts of the plant such as cortex and pith. It mainly acts as a packing tissue, providing mechanical SUPPORT. It also helps in the storage of food. Based on the specific functions, parenchyma can be further classified into Aerenchyma and Chlorenchyma.

Collenchyma – These cells are living cells and have an elongated shape. The corners of the cell wall are thickened. There is very little intercellular space present. The collenchyma tissue can be located in the leaf stalks, below the epidermis etc. Its main function is to provide flexibility to the plants as well as mechanical support.

Sclerenchyma – The cells of the sclerenchyma tissue are DEAD. The cell wall is very thick due to the deposition of lignin. The cells of this tissue can be in different shapes and sizes. They are generally located in the leaf veins, hard coverings of the seeds and can also be found SURROUNDING the vascular bundle. The main function of the sclerenchymatic tissue is to provide rigidity and mechanical support to the plant body. They also make the plant stiff and hard.

Answer:1. Herbivores- ANIMALS that only eat plant.

Herbivore is the anglicized form of a modern Latin coinage, herbivora, cited in Charles Lyell‘s 1830 Principles of Geology. Richard Owen employed the anglicized term in an 1854 work on fossil teeth and skeletons. Herbivora is DERIVED from the Latin herba meaning a small plant or herb and vora, from vorare, to eat or devour.

A herbivore is an animal that gets its energy from eating plants, and only plants. Many herbivores have special digestive systems that let them digest all kinds of plants, including grasses.

Example: Cow

2. Carnivores - Animals eat only other animals.

A carnivore meaning ‘meat eater’ (Latin, carne meaning ‘flesh’ and vorare meaning ‘to devour’) is an organism that derives its energy and nutrient requirements from a diet consisting mainly or exclusively of animal tissue, whether through predation orscavenging. Animals that depend solely on animal flesh for their nutrient requirements are considered obligate carnivores while those that also consume non-animal food are considered facultative carnivores. A carnivore that sits at the top of the foodchain is an apex predator.

Example: Tiger3. Omnivores- Animals that eat both plants and animals.

An Omnivore, meaning ‘all-eater’ (Latin omni, vorare: “all, everything”, “to devour”), is a polyphage (“many foods“) species that is a consumer of a variety of material as significant food sources in their natural diet. These foods may include plants, animals, algae and fungi.

Omnivores often are opportunistic, general feeders with neither carnivore nor herbivore specializations for acquiring or processing food, and are CAPABLE of consuming and do consume both animal protein and vegetation. Many omnivores depend on a suitable mix of animal and plant food for long-term good health and reproduction.

Omnivores eat plants, but not all kinds of plants. Unlike herbivores, omnivores can’t digest some of the substances in grains or other plants that do not produce fruit. They can eat fruits and vegetables, though. Some of the insect omnivores in this simulation are pollinators, which are very IMPORTANT to the life cycle of some kinds of plants.

Explanation:

As coronavirus (COVID-19) has impacted communities around the world, many people have wondered whether there are steps they can take to stay healthy. Everyday preventive measures—such as handwashing, avoiding contact with sick individuals, and good hygiene—can GO a long way in reducing your risk for viruses, bacteria, and other pathogens.

In addition, however, there is evidence that nutrition and other lifestyle measures influence immune strength and susceptibility to infectious diseases. Whether these measures do or do not influence susceptibility to COVID-19 or its clinical course is not yet known. However, there is every reason to put what we do know about foods and immune defenses to use. Here is what we know now:

Diet

Eating a low-fat, plant-based diet may help give the immune system a boost. The immune system relies on white blood cells that produce antibodies to combat bacteria, viruses, and other invaders. Vegetarians have been shown to have more effective white blood cells when compared to nonvegetarians, DUE to a high intake of VITAMINS and low intake of fat.1

Eating a low-fat diet may also be protective. STUDIES have shown that limiting dietary fat helps strengthen immune defenses. Research also shows that oil may impair white blood cell function and that high-fat diets may alter the gut microbiota that aid in immunity.2

Maintaining a healthy weight can also benefit the immune system. Obesity has been linked to increased risk for influenza and other infections such as pneumonia.3 Plant-based diets are effective for weight loss, because they are rich in fiber, which helps fill you up, without adding extra calories. Fiber can also lower BMI, which is linked to improved immunity.4 A plant-based diet has also been shown to reduce inflammatory biomarkers.5

Vitamins, Minerals, and Antioxidants

Studies have shown that fruits and vegetables PROVIDE nutrients—like beta-carotene, vitamin C, and vitamin E—that can boost immune function. Because many vegetables, fruits, and other plant-based foods are also rich in antioxidants, they help reduce oxidative stress.6

This article needs additional citations for verification.

Merriam-Webster defines chemotaxonomy as the method of biological classification based on similarities in the structure of certain COMPOUNDS among the organisms being classified. Advocates ARGUE that, as proteins are more closely controlled by genes and less subjected to NATURAL selection than the anatomical features, they are more reliable indicators of genetic relationships. The compounds studied most are proteins, amino acids, nucleic acids, peptides etc.

Physiology is the study of working of organs in a living being. Since working of the organs involves chemicals of the body, these compounds are called biochemical EVIDENCES. The study of morphological change has shown that there are changes in the structure of animals which result in evolution. When changes take place in the structure of a living organism, they will naturally be accompanied by changes in the physiological or biochemical processes.

John Griffith Vaughan was one of the pioneers of chemotaxonomy.
