Homologous structures share a similar embryonic origin; ANALOGOUS organs have a similar function. For EXAMPLE, the bones in the front FLIPPER of a whale are homologous to the bones in the human ARM. These structures are not analogous. The WINGS of a butterfly and the wings of a bird are analogous but not homologous.

Melatonin is a hormone that the pineal gland in the brain produces. People can also take it as a natural or synthetic supplement to promote restful sleep. Melatonin fulfills many FUNCTIONS in the BODY, but it is MOSTLY known for MAINTAINING circadian rhythms.

on is DEFINED as movement of substances along the concentration gradient. This kind of movement is seen in many of the biological systems normally.Even we get to see the movement of substances against the concentration gradient. This type of movement is also known as "Up Hill" type of movement where ATP acts as the source of energy.This type of Up-Hill movement is facilitated by the help of Pumps which UTILISE ATP and TRANSPORT the molecules from a region of low concentration to a region of HIGH concentration.The reason why this is required is that :Let's take an example first :Whenever we suffer from dehydration , we need to take water , glucose (sugars). Sugars are transported from the lumen of intestine to the enterocytes. This is an example of Active Transport. So active transport is necessary for maintaining the storage of necessary substances inside a cell . If active transport was absent , it would lead to loss of those substances via Passive transport.

⭕A child's growth and development can be divided into four periods:▶️Infancy▶️Preschool years▶️Middle childhood years▶️AdolescenceSoon after birth, an infant normally loses about 5% to 10% of their birth weight. By about age 2 weeks, an infant should start to gain weight and grow quickly.By age 4 to 6 months, an infant's weight should be double their birth weight. During the second half of the first year of life, growth is not as rapid. Between ages 1 and 2, a toddler will gain only about 5 pounds (2.2 kilograms). Weight gain will REMAIN at about 5 pounds (2.2 kilograms) per year between ages 2 to 5.Between ages 2 to 10 years, a child will grow at a steady pace. A final growth spurt begins at the start of puberty, sometime between ages 9 to 15.The child's nutrient needs correspond with these changes in growth rates. An infant needs more calories in relation to size than a PRESCHOOLER or school-age child needs. Nutrient needs increase again as a child gets close to adolescence.A healthy child will follow an individual growth curve. However, the nutrient intake may be different for each child. Provide a diet with a wide variety of foods that is suited to the child's age.Healthy eating habits should begin during infancy. This can help prevent diseases such as high blood pressure and obesity.⭕INTELLECTUAL DEVELOPMENT AND DIETPoor nutrition can cause problems with a child's intellectual development. A child with a poor diet may be tired and unable to learn at school. Also, poor nutrition can make the child more likely to get SICK and miss school. Breakfast is very important. Children may feel tired and unmotivated if they do not eat a good breakfast.The RELATIONSHIP between breakfast and improved learning has been clearly shown. There are government programs in place to make sure each child has at least one healthy, balanced meal a day. This meal is usually breakfast. Programs are available in poor and underserved areas of the United States.Talk to your health care provider if you have concerns about your child's growth and development.Explanation:MARK IT AS BRAINLIST

As the soil absorbs manure, nutrients are released. ... Adding manure to compacted soil helps LOOSEN the soil. Manure PRODUCES increased soil carbon, which is an important source of ENERGY that makes nutrients available to plants. Other benefits of manure include REDUCED runoff and leaching of nitrates in the soil.

tion:Placental transfer of maternal IgG antibodies to the fetus is an important mechanism that provides protection to the infant while his/her humoral response is INEFFICIENT. IgG is the only antibody CLASS that significantly crosses the human placenta. This crossing is mediated by FcRn expressed on syncytiotrophoblast cells. There is evidence that IgG transfer DEPENDS on the following: (i) maternal levels of total IgG and specific antibodies, (II) gestational age, (iii) placental integrity, (iv) IgG SUBCLASS, and (v) nature of antigen, being more intense for thymus-dependent ones. hope it helps you mate..........

cture of Mitochondria: They are made of two membranes. The outer membrane COVERS the organelle and contains it like a skin. The inner membrane folds over many times and creates layered structures called cristae. The fluid contained in the mitochondria is called the matrix.FUNCTION: Mitochondria are known as the powerhouses of the cell. They are organelles that act like a digestive system which takes in nutrients, breaks them down, and creates energy rich molecules for the cell. The biochemical processes of the cell are known as cellular respiration.2) Structure of Plastids:The plastid is a membrane-bound organelle found in the cells of plants, algae, and some other eukaryotic organisms. ... They often CONTAIN pigments used in photosynthesis, and the types of pigments in a plastid determine the cell's color.FUNCTION:Plastids are the SITE of manufacture and storage of important chemical compounds used by the cells of autotrophic eukaryotes. They often contain pigments used in photosynthesis, and the types of pigments in a plastid determine the cell's color.3) STRUCTURE OF VACUOLES: Vacuoles are membrane-bound sacs within the cytoplasm of a cell that function in several different ways. In mature plant cells, vacuoles tend to be very large and are extremely important in providing structural support, as well as serving FUNCTIONS such as storage, waste disposal, protection, and growth.

Three outbreeding devices that flowering plants have developed: Receptivity of STIGMA and release of the pollen grain is not synchronized, i.e., stigma becomes RECEPTIVE much before pollens are released or after they are released to avoid self-pollinationhope it GIVE you HELP

The out breeding devices that FLOWERING plants have developed receptivity STIGMA that releases POLLEN grain that is not synchronized which helps stop self -POLLINATION.

Fertilisation. When a pollen grain lands on the stigma of a flower of the correct SPECIES , a pollen TUBE begins to grow. It GROWS through the STYLE until it reaches an ovule inside the OVARY. The nucleus of the pollen then passes along the pollen tube and fuses (joins) with the nucleus of the ovule.

couplet in taxanomic key MEANS. Taxonomic keys are written CHARACTERISTIC information that helps a person to identify an unknown species of living organism. The taxonomic key PROVIDES a certain structure on the basis of which the user can sort out the taxonomic position of the unknown species.

In plants, the transpiration stream is the UNINTERRUPTED stream of WATER and solutes which is taken up by the roots and transported via the xylem to the leaves where it evaporates into the air/apoplast-interface of the substomatal CAVITY. It is driven by capillary action and in some plants by root PRESSURE.

Getting rid of carbon dioxide. In mammals, RED blood cells deliver oxygen to TISSUES and REMOVE carbon dioxide. Key to this essential process is a membrane protein CALLED anion exchanger 1 (AE1) which transports bicarbonate (formed from carbon dioxide) out of red blood cells in EXCHANGE for chloride.

NATURAL VEGETATION AND WILDLIFE. ... Importance of Natural Vegetation: Vegetation provides shelter to animals and provides US with timber and MANY other forest produce. Plants also produce oxygen when they MAKE FOOD and oxygen is the gas we breathe. Plants protect soil from degradation.

tion: Digestion typically begins in the stomach when pepsinogen is converted to PEPSIN by the action of hydrochloric ACID, and continued by trypsin and chymotrypsin in the SMALL intestine. Before the absorption in the small intestine, most proteins are already reduced to single amino acid or peptides of several amino acids.Proteins ingested in the diet are digested into amino acids or small peptides that can be absorbed by the intestine and transported in the blood. Another source of amino acids is the degradation of defective or unneeded cellular proteins. When proteins are digested or BROKEN down, amino acids are left. Zymogenic cell or peptic cell in the stomach that releases pepsinogen and CHYMOSIN. This inactive pepsinogen, on exposure to hydrochloric acid, gets converted to the active enzyme pepsin. ... Hence, the end product of protein digestion is amino acids.

WIND MILL: A device used to CONVERT Wind energy into the mechanical energy is called wind mill.It consists of a WHEEL with blade cut into its OUTER rim. The wheel ROTATES about an axle mounted on a pole. The wind energy is used to rotate the wheel about its axis.Wind mill is used for operating water pumps, grinders and is also used to produce electricity.WIND ENERGY FARM: The electricity produced by a single windmill is very small, which cannot be used for commercial purpose. To produce electricity on a large scale, a large number of wind mils are erected in HIGH wind energy region. The region where large number of windmills are elected to produce electricity is called wind energy farm.

cess of RESPIRATION in PLANTS involves using the sugars produced during photosynthesis plus oxygen to PRODUCE energy for plant growth. In many ways, respiration is the opposite of photosynthesis. In the natural environment, plants produce their own food to survive. They USE the carbon dioxide (CO2) from the environment to produce sugars and oxygen (O2), which can later be utilized as a source of energy. While photosynthesis takes place in the leaves and stems only, respiration occurs in the leaves, stems and roots of the plant. The process of respiration is represented as follows: C6H12O6 + 6O2 → 6CO2 + 6H2O + 32 ATP (energy) As with photosynthesis, plants get oxygen from the air through the stomata. Respiration takes place in the mitochondria of the cell in the presence of oxygen, which is called "aerobic respiration". In plants, there are two types of respiration: dark respiration and photo respiration. The first kind occurs in the presence or absence of light, while the second occurs exclusively in the presence of light.
