Which are the four major groups of human pathogens?
A. bacteria, Viruses, Fungi and Protists
B. Protists, insects, bacteria and viruses
C. Fungi, Protists, Toxins and Bacteria
D. Viruses, Fungi, Protists and Toxins
Answers
Bacteria, Viruses, Fungi and Protists are the four major groups of human pathogens. Therefore, option (A) is correct.
What are human pathogens?Bacteria are microorganisms that are made up of a single cell and can be the source of illnesses such as strep throat, TB, and infections of the urinary system. The common cold, influenza, and COVID-19 are all illnesses that can be caused by viruses, which are non-living particles that can only multiply inside of a living host cell.
Infections such as ringworm, athlete's foot, and thrush can be caused by fungi, which are multicellular organisms that can spread from person to person. Protists are single-celled organisms that are capable of causing a variety of diseases, including giardiasis, malaria, and amoebic dysentery.
Insects and toxins, despite the fact that they are capable of inflicting harm on humans as well, are not considered to be major classes of human pathogens.

Explanation:
Why DNA is absent in blood plasma?
Answers
Answer:
Why do blood cells not have DNA?
Because of the lack of nuclei and organelles, mature red blood cells do not contain DNA and cannot synthesize any RNA, and consequently cannot divide and have limited repair capabilities. The inability to carry out protein synthesis means that no virus can evolve to target mammalian red blood cells.
Explanation:
Blood plasma is a light amber-coloured liquid component of blood in which blood cells are absent but contains proteins and other constituents of whole blood in suspension. It makes up about 55% of the body's total blood volume. It is the intravascular part of extracellular fluid (all body fluid outside cells). It is mostly water (up to 95% by volume) and contains important dissolved proteins, hormones, carbon dioxide (plasma being the main medium for excretory product transportation), and oxygen. It plays a vital role in an intravascular osmotic effect that keeps electrolyte concentration balanced and protects the body from infection and other blood-related disorders.
Blood plasma is separated from the blood by spinning a tube of fresh blood containing an anticoagulant in a centrifuge until the blood cells fall to the bottom of the tube. The blood plasma is then poured or drawn off. For point-of-care testing applications, plasma can be extracted from whole blood via filtration or via agglutination to allow for rapid testing of specific biomarkers. Blood plasma has a density of approximately 1,025 kg/m3 (1.025 g/ml).
Blood serum is blood plasma without clotting factors.
Plasmapheresis is a medical therapy that involves blood plasma extraction, treatment, and reintegration.
Fresh frozen plasma is on the WHO Model List of Essential Medicines, the most important medications needed in a basic health system. It is of critical importance in the treatment of many types of trauma that result in blood loss and is therefore kept stocked universally in all medical facilities capable of treating trauma.

eous rocks are formed?
Answers
Igneous rocks contain randomly arranged interlocking crystals. The size of the crystals depends on how quickly the molten magma solidified: magma that cools slowly will form an igneous rock with large crystals. lava that cools quickly will form an igneous rock with small crystals. their visual appearance shows individual crystals interlocked together to form the rock mass. The cooling of magma deep in the Earth is typically much slower than the cooling process at the surface, so larger crystals can grow. Intrusive igneous rocks form in magma chambers that are deep underground. Many kilometers below the Earth's surface, molten rock called magma flows into cracks or underground chambers. There, the magma sits, cooling very slowly over thousands to millions of years. An intrusion is a body of igneous (created under intense heat) rock that has crystallized from molten magma. Gravity influences the placement of igneous rocks because it acts on the density differences between the magma and the surrounding wall rocks (country or local rocks). The most common river rocks used in landscaping and decorative construction are made of granite. Granite belongs to the "intrusive" category of igneous rock, which means it formed below the earth's surface as magma slowly cooled and crystallized. The rocks that form Earth's crust are continually destroyed and remade in an endless process called the rock cycle. Rock is formed by melting; by cooling and solidifying; by changing through heat and pressure; by weathering and erosion; and by compression and cementation.

On the other hand, if the competition for resources involves organisms of different species, the competition is said to be indirect or interspecific.
Thus, all gray wolves feeding on the same type of prey and two male deers fighting over a mate are examples of direct or intraspecific competition.

The dense needle of Douglas fir trees preventing light from reaching the forest floor will have an immediate effect on the understory producers.
What are producers?Producers are green plants that are capable of utilizing solar radiation to fix carbon dioxide into carbohydrates.
A forest contains several layers of trees and may or may not have a herbaceous cover of herbaceous plants.
If the tree layers permit light to reach the floor of the forest, herbaceous ground cover may thrive. Otherwise, only a few, shade-tolerant herbs will grow on the ground layer.
