•A cell junction is a type of structure that exists within the tissue of some multicellular organisms, such as animals. •Cell junctions consist of multiprotein complexes that provide contact between neighboring cells or between a cell and the extracellular matrix.

We must conserve our forests to conserve the biodiversity which we have inherited. This is because the loss of biodiversity leads to the loss of ecological stability of the forest ecosystem.

Causes for deforestation taking place :

(1) The forest wood is used as a fuel.

(2) The forest wood is used for construction purposes like making doors, windows and f

Plants are necessary for us in all ways, the materials we get from them are worth more, There is no survival without plants.

Here are some things that we get from plants-:

•Oxygen- Plants take in CO2 and give out Oxygen, living gas for all humans and animals. This way plants are the most important part of our life as without oxygen there will be no survival.

•Medicinal products - Plants has many things inside them which can cure a disease, Ayurveda products ,we call it as. Like turmeric, neem, etc.

•Wood- We get wood for the trunks of trees, we use wood for many purposes, like for furniture, decorations, etc.

•Cotton- Cotton plants provide us cotton which is used in hospitals, and as an aid, also cotton is used for other more purposes.

•Gum, paper, jute- Everything is provided from these plants.

Ans :- a small gland that secretes sweat, situated in the dermis of the skin. Such glands are found over most of the body, and have a simple coiled tubular structure.

Sweat glands, also known as sudoriferous or sudoriparous glands, from Latin sudor, meaning 'sweat', are small tubular structures of the skin that produce sweat. Sweat glands are a type of exocrine gland, which are glands that produce and secrete substances onto an epithelial surface by way of a duct.

The accessory glands of the male reproductive system are the seminal vesicles, prostate gland, and the bulbourethral glands. These glands secrete fluids that enter the urethra

Gastric JuicesIn addition to the mechanical digestion caused by churning, there is also chemical digestion happening within the stomach. Specifically, we see the chemical digestion of proteins by digestive fluids. These acidic digestive fluids that are secreted by the gastric glands in the mucous membrane of the stomach are collectively referred to as gastric juices. We previously learned that secretions of gastric juices from the gastric glands are regulated by the parasympathetic nervous system. This involuntary nervous system increases secretions when activated by the sight, smell or physical presence of food in the digestive tract. In addition, the presence of food and the change in the pH of the stomach stimulate the release of a hormone called gastrin. This is a hormone secreted by glands in the mucous membrane of the stomach that stimulates the production of gastric juices.

Epithelial cells secrete enzymes in the gastric glandsGastric Epithelial CellsSo, you can see that there are a couple of triggers for the production of gastric juices, and this leads to a surprisingly large volume of gastric juice produced during the day. Under normal circumstances, approximately two or three liters of gastric juices are produced in your stomach in a 24-hour period. That is enough to fill at least one 2-liter bottle of soda, and this is all happening inside of you without your conscious awareness.

The parathyroid glands are four tiny glands, located in the neck, that control the body's calcium levels. Each gland is about the size of a grain of rice (weighs approximately 30 milligrams and is 3-4 millimeters in diameter). The parathyroids produce a hormone called parathyroid hormone (PTH).PTHraises the blood calcium level by:

a.breaking down the bone (where most of the body's calcium is stored) and causing calcium release

b.increasing the body's ability to absorb calcium from food

c.increasing the kidney's ability to hold on to calcium that would otherwise be lost in the urine.

Classification is based on similarities and differences among organisms.Organisms having same type of features and level of development are kept in the same class. Organisms resemble with each other because if we trace back their origin we find that they were developed from common ancestors. Evolution means studying organisms based on the complexity of their structure and features and arranging them in their order of complexity. So it is evident that both classification and evolution are interlinked.

1. The 2 main thyroid hormones are T3 (triiodothyronine) and T4 (thyroxine). T3 and T4 regulate your body's temperature, metabolism and heart rate. The amount of thyroid hormones secreted is controlled by another hormone, called thyroid stimulating hormone (TSH), which is released from thepituitarygland in your brain.

2.Hormones produced by the pituitary gland. Adrenocorticotrophic hormone (ACTH) Thyroid-stimulating hormone (TSH) Luteinising hormone (LH) Follicle-stimulating hormone (FSH) Prolactin (PRL) Growth hormone (GH) Melanocyte-stimulating hormone (MSH)

3. Primary hormones secreted by the pancreas include:Gastrin: This hormone aids digestion by stimulating certain cells in the stomach to produce acid.Glucagon:Glucagonhelpsinsulinmaintain normal blood glucose by working in the opposite way ofinsulin.

Mammals are the vertebrates within the class Mammalia, a clade of endothermic amniotes distinguished from reptiles by the possession of a neocortex, hair, three middle ear bones, and mammary glands. Females of all mammal species nurse their young with milk, secreted from the mammary glands.Mammary Glands

Mammals got their name from this evolutionary adaptation. Mammary glands are only found on mammalian species, and no other species. Mammary glands evolved from modified sweat glands to produce milk for offspring. Only female mammals produce milk, an adaptation that requires an investment of time and energy to care for the newborn offspring.

Hair

Hair on mammals is an adaptation that provides insulation to keep the animal warm, provide protection to the animal's skin, provides camouflage through color patterns and helps the animal by providing greater sensory input through touch.

Middle Ear Bones

All mammals have three middle ear bones, commonly called the hammer, anvil and stirrup. Their scientific names are malleus, incus and stapes. The hammer and anvil evolved from the jaw bones from primitive mammal ancestors. These bones work together to transmit vibrations to the eardrum.

Sweat Glands

Sweat glands, while being unique to mammals, aren't present in all mammals. For example, the whale has no sweat glands, but doesn't need them because it lives in the ocean.

Temperature Regulation

While most mammals are warm-blooded, not all are able to regulate their temperature, which is the definition of being warm-blooded. Bats and mole rats can't regulate their body temperatures; whereas bees, birds and the hawk moth can.

option (a) is correct.

Pteridophytes have a dependence on water. Reproduction and fusion of gametes can happen in the presence of water.

when dead cells come near lysosomes they burst and release destructive enzyme to digest the dead cells in this process they digest their own cells so lysosomes are known as suicidal bags of the cells

Lysosomes are known as suicidal bags of cell because they are capable of breaking down all waste materials.Its function is to digest waste materials in the cell.

Ans :- Lysosomesare cellular organelles that contain digestive enzymes that break down waste materials, foreign material and cellular debris. Lysosomes are capable of digesting nucleic acid, polysaccharides, fats, and proteins. Along with them lysosomes also digest or damage its own cells by its own enzymes, which lead to cell death. This process is called as autolysis. Hence lysosomes are also called as suicide bags.

please like the solution 👍 ✔️👍

When the cell is damaged then the lysosomes may burst releasing all the digestive enzymes and thus killing the cell as well as themselves. That is why lysosomes are known as suicidal bags

DNAs are the carriers of genetic information. For an organism to produce its own kind, it becomes necessary that the offspring get similar DNAs as in parents. DNA replication is the way through which a cell makes additional copies of DNA so that they can be transferred to the offspring. This explains how DNA copying is an essential part of the process of replication.

Eachwater lilyflower produces pollen. ... Pollen from otherwater lilyflowers is washed off of the insect's body into the pool of liquid, where it dissolves and enters the stigma, fertilizing the flower and beginning the seed production cycle.In Vallisneria pollination is through hdrophilly ie through water. In Valilisneria, the female flower appear on the surface of the water as it have a long stalk. The pollen grains released by the male flower reaches to female flower for fertilisation through water currents.In sea grass, the female flowers are seen submerged in water and the pollen grains are released inside the water. The pollen grains reach stigma for pollination.The moth and Yucca plant is mutually benefited by their association. The moth lay eggs in the ovary of yucca flower which helps the plant in pollination. When the egg hatches, the larva feed the fruits and seeds of the plant. Thus the plant provide food and shelter to the moth and moth helps the plant to pollinate.

Lungscontain millions ofalveoliwhich provide asurfacefor theexchange of gases. An extensive network of blood vessels is present in the wall of thealveoli. By lifting our ribs and flatten the diaphragm, the chest cavity becomes spacious. Air is sucked into thelungsandalveoli.

Nutrients are molecules in food that all organisms need to make energy, grow, develop, and reproduce. There are two major types of nutrients that we need to supply our bodies with energy, macronutrients and micronutrients.

It helps in the following ways:-1) It breaks downs large pieces of soilinto finer particleswhich helps in better soaking of water in soil and for planting seeds.2)It brings up the nutrients present below the soil up so that the plants can get the necessary nutrients easily.3) It also helps in the removal of weeds and undesirable roots.

Vegetative propagation has some inherent advantages. It takes less time to grow a plant through vegetative propagation. Different traits of a species can be developed on the same plant through this process. Many plants grown through vegetative propagation take less time to give fruits and other beneficial plant produce. These are the reason, vegetative propagation is practiced for growing some types of plants.

Vegetative propagation method is used for growing certain plants which do not produce viable seeds. It is also used for growing of plants bearing superior traits, because they produce genetically identical plants.

Hydroponics is a subset of hydroculture, which is a method of growing plants without soil by using mineral nutrient solutions in a water solvent.
