When all the vital functions which are necessary for life are performed by a single cell then such cell is called unicellular organism. Some examples of unicellular organisms are Amoeba, Paramecium,photoplanktons etc.

Red blood cells are formed in the red bone marrow of bones. Stem cells in the red bone marrow called hemocytoblasts give rise to all of the formed elements in blood. If a hemocytoblast commits to becoming a cell called a proerythroblast, it will develop into a new red blood cell.

The formation of a red blood cell from hemocytoblast takes about 2 days. The body makes about two million red blood cells every second.

Waterway Pollution. The use of chemical fertilizers on crops can have adverse effects on waterways caused by chemical run off of the excess fertilizer. The over-abundance of nutrients in the water reduces the amount of oxygen. ... The result is oxygen depletion causing the fish to die

Anomalous expansion of water refers to water's unusual ability, due to which it expands instead of contracting when cooled. Due to some reasons like rains or a flowing river, water enters the rocks through small spaces in between them. In winters, in areas with extremely low temperatures, this water expands due to its abilities and thus causes the rocks to crack.

Biogas refers to a mixture of different gases produced by the breakdown of organic matter in the absence of oxygen. Biogas can be produced from raw materials such as agricultural waste, manure, municipal waste, plant material, sewage, green waste or food waste. Biogas is a renewable energy source.

Like fossil natural gas, the essentialcomponent of biogas, which is responsible for the energy it contains, is methane (CH4), a flammable gas. Othercomponents of biogasare water (H2O), oxygen (O2) and traces of sulphur (S2) and hydrogen sulphide (H2S).

In unicellular They are single celled organisms like Amoeba and they have a large surface area to volume ratio. They obtain nutrients by diffusion, facilitated diffusion or active transport across their cell membrane. They use holzoic nutrition, taking in larger molecules by endocytosis to food vacuoles which then fuse with lysosomes and their contents are then digested by lysosomal enzymes.The products of digestion are then absorbed into the cytoplasm and anthing indigestible is egested by exocytosis

Amoeba undergoes binary fission each cell splits into two daughter cells which is all similar to its parent cell. Binary fission is a never ending process.

The life span of parent cell is little more than 2 days. After that mother cell splits and daughter cells form.

Anaerobic respiration is respiration using electron acceptors other than molecular oxygen. Although oxygen is not used as the final electron acceptor, the process still uses a respiratory electron transport chain called physolmere; it is respiration without oxygen.

It is the break down of glucose in absence of oxygen.Less energy is released.

Producerscan make their own food by capturing the sun's energy, but consumers anddecomposerscan't. Consumers need to eat other organisms to obtain energy.Decomposersare like the recyclers of nature. They obtain energy for their own needs while returning simple molecules to the environment.

Consumers, on the other hand, consume materials generated by theproducersand hence they use the food, nutrients and oxygen. Animals, man, etc. are good examples ofconsumers.Producersare capable of photosynthesis, a process by which they covert light energy into chemical energy, whileconsumersuse respiration.

Ciliated epitheliumis a thin tissue that has hair-like structures on it. These hairs, calledcilia, move back and forth to help move particles out of our body. We findciliated epithelialtissue in our respiratory tract and in the fallopian tubes of women.

Ciliated epithelium performs the function of moving particles or fluid over the epithelial surface in such structures as the trachea, bronchial tubes, and nasal cavities. It often occurs in the vicinity of mucus-secretinggoblet cells.

These are those cells which have cilia on their surface and their main function to remove mucous in wind pipe; ciliated epithelium is also present in fallopian tube, uterus and central part of spinal cord.

ciliated epithelial tissue is the tissue of which cell are long and have hair like projection called cilia so it is called ciliated epithelial tissue

cilia containing epithelium is called ciliated epithelium.. eg.in fallopian tube,respiratory tract etc..Cilia helps in the movement of particles in one direction..

Cuboidal epithelial cells are cube like. They form the lining of kidney tubules and ducts of salivary glands, where it provides mechanical support.

A simple squamous epithelium is a single layer of flat cell in contact with the basal lamina of the epithelium

simple squamous epitheliumis a single layer of flat cells in contact with thebasal lamina(one of the two layers of thebasement membrane) of theepithelium.[1]This type of epithelium is often permeable and occurs where small molecules need to pass quickly through membranes viafiltrationordiffusion. Simple squamous epithelia are found incapillaries,alveoli,glomeruli, and other tissues where rapid diffusion is required.[2]

squmous epithelium is the group of cells with irregular boundaries which forms the air sacs of lungs and walls of blood vessels...and form the diffusion boundary..

simple squamous epithelial is a single layer of cell in contact With the basal lamina of the epithelium

Epithelium is not vascularized (capillaries do not directly reach its cells). It exchanges substances by diffusion with the connective tissue located under it.

Since epithelium is not vascularized, the tiny skin injuries or scratches that happen all the time do not cause bleeding and do not expose the blood to contamination from foreign agents. This is an important protective strategy of evolution.

The structural homology among streamlined, biflagellated male gametes of Selaginella and bryophytes

So, the answer is option B

A simple columnar epithelium is a tissue made of a single layer of long epithelial cells that are often seen in regions where absorptionand secretion are important features. The cells of this epithelium are arranged in a neat row with the nuclei at the same level, near the basal end. In a cross-section of the organ, these cells appear like thin columns, differentiating them from flattened squamous cells and square-shaped cuboidal cells. Among simple epithelia, this sub-type can withstand some degree of wear and tear.

For the eggs to be fertilized, the hen and rooster must mate first, and this process must occur prior to the formation of the egg. Thus, if the hen has mated and she lays an egg, then that egg is fertilized. ... In this process, hold the egg up to the candlelight so you can point out the blood spots and embryo.

Given, power of pump = 2kW =2000W

Time (t)= 60sec

Height (h) = 20m

g = 10m/s2

As you know, power =work done per unit time.

Work done = mgh = m ×10×20 =200m

Therefore, 2000W = 200m/60s

Therefore, m = 600kg

So, the pump can raise 600kg of water in one minute.

Speed of sound depends primarily on thedensityand viscosity of the medium through which it propagates. Sotemperature,humidity(ifnonliquid medium) andpressureare also factors as they impact thedensityand viscosity of the medium, especially if the sound wave propagates through fluids.

Pollution is the introduction of contaminants into the natural environment that cause adverse change. Pollution can take the form of chemical substances or energy, such as noise, heat or light. Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants.

Inside our human body, there are many organs and systems that perform various actions for our survival. But still many don't know completely about our inside body. It's a vast subject! Thus, man is called a moving museum as there are still wonders to be explored and view within us. And it's a wonder that it makes up a great museum indeed a moving one.

Anthocyanins are water soluble pigments comes under phenolic flavanoids category.

It is responsible for providing colors to flowers therefore helpful in attraction of pollinators and chief component in plant defensive systems from preventing grazing from herbivores.

In the absence of anthocyanin pollination will be suffered and grazing by herviores will increase.

answer = (3) endodemis

Casparian strip a band of suberin, an impermeable substance, found in the endodermal cell walls of plant roots

endoderm is the correct answer

root epidermis, epidermal hairs, termed root hairs are common and are specialized for absorption of water and mineral nutrients. In plants with secondary growth, the epidermis of roots and stems is usually replaced by a periderm through the action of a cork cambium.

Function of the Epidermis:

Theepidermisis the outermost layer of our skin. Tough and resilient, protection is its number one job. Think of a parka you may wear in the winter. The inside is lined with soft fleece, providing a layer of warmth. But the outside is made of a strong waterproof material that lets nothing through. It is a similar situation with our own epidermis

The protective qualities of our outer layer are vast. Our epidermis is waterproof, which is why we don't swell with liquid each time we bathe. The cellular structure of the epidermis also forms a highly effective barrier against germs. When skin is healthy and intact, it is difficult for bacteria and viruses to make an entrance. In addition, cells of the epidermis have the miraculous ability to regenerate, or grow back, unlike many other cells in the body. When we suffer from a wound, healthy skin heals and replaces damaged cells with ease.

It prevents the contamination of plant tissues with external water, dirt and microorganisms. Thecuticleof Nelumbo nucifera have ultra hydrophobic and self cleaning properties. A plantcuticleis a protective film covering theepidermisof leaves, young shoots and other aerial plant organs without periderm.

epidermis provide outer protection covering fo plants and protects it from external influence

Epidermis : 1.Features : *It is the outer protecting layer of plant. *It covers whole plant body. *:Stomata' are present on the outer layer of the epidermis. *It contains chemical substance with water proof qualities called 'cutin'. 2.Functions : *It protects the plant from injury. *It protects the plant from germs. *It protects the plant from water. *It controls the exchange of gases by controlling the 'stomata'.

A food chain begins with plants because a herbivore eats plants and a carnivore or an omnivore eats the herbivore. In this way the chain continues as green plants as their starting point. If green plants weren't there at the staring of a food chain, no life would have existed today.

Cells get nutrients from their environment, but where do those nutrients come from? Virtually all organic material on Earth has been produced by cells that convert energy from the Sun into energy-containing macromolecules. This process, called photosynthesis, is essential to the global carbon cycle and organisms that conduct photosynthesis represent the lowest level in most food chains
