m Placenta is DERIVED from a Greek word meaning flat cake. It is defined as a special KIND of tissue connection between the mother and the fetus, formed by the inner lining of uterus and the fetal membranes for the purpose of physiological exchange of materials.Role of Placenta :Placenta is formed by the fusion of uterine tissues and fetal membranes. It serves mainly as for the transport of nutrients and oxygen from the mother to the fetus.It serves as a placental BARRIER and and also prevents the direct mixing of both maternal and fetal blood.There are different types of classification of placenta based on the type of fetal membranes, based on the distribution of villi, based on the nature of contact and based on histology [ types of tissues].The term Amnion is defined as the fetal membrane or an EXTRA embryonic membrane. The animals which developing an amnion are called Amniota. It surrounds the embryo. It is made up of two layers, namely an OUTER somatic mesoderm and an inner ectoderm.It encloses a cavity or a sac known as amniotic cavity or an amniotic sac. It is filled with a fluid called amniotic fluid. The amnion is connected to the embryo on the ventral side by a stalk called somatic umblicus. Amnion ruptures at the time of birth.Role of amniotic sac :The embryo is freely immersed and bathed in the amniotic fluid. Hence it functions as the artificial swimming pool of the embryo. As the amniotic fluid is more viscous and gelatinous, it functions as an efficient shock absorber. Thus the embryo is protected from external as well as internal mechanical pressures. The amnion prevents the adhesion of embryo to the other parts. The amnion prevents the adhesion of embryo to the other parts. The amnion provides facilities for the free movement of the embryo. It helps in respiration

n from urea can be lost to the atmosphere if fertilizer urea remains on the SOIL surface for extended periods of time during warm weather.The key to most efficiently using urea is to incorporate it into the soil during a tillage operation. You can also blend it into the soil with irrigation WATER. As little as 0.25 inches of RAINFALL is sufficient to blend urea DEEP enough into the soil so AMMONIA losses won’t occur.Mark me as the brainliest

sue concerned with the movement of body parts and the locomotion of animals is called muscle tissue. It is ALSO called muscular tissue or contractile tissue. According to their structure, location, and functions, muscle tissues are classified into three groups. They are striated muscles, non striated muscles and cardiac muscles.Striated Muscle: The muscle which shows cross STRIATIONS are called striated muscles or striped muscles. They are mostly attached to the bones by tendons and so called skeletal muscles. Their activity is under the control of will. So, they are also called voluntary musclesNon striated muscle: The muscle which show no cross striations are called non striated muscles or unstriped muscles. They look SMOOTH, hence are called smooth muscles. Their activity of these muscles are not under the control of the will of the animal, so they are known as involuntary muscles. These muscles are seen in hollow internal organs (VISCERA) such as stomach, intestine, blood vessels, urinary bladder, uterus etc.Striated vs Non Striated MuscleStriated Muscle1. Striations present.2. It is voluntary in action3. The muscle fibres are long and cylindrical with blunt ends.4. The fibres are multinucleated.5.Sarcoplasmic reticulum is well developed.6. Sarcomeres present.7. Numerous mitochondria and glycogen granules are present8. Striated muscle is seen attached to skeleton.Example: Biceps muscleNon Striated Muscle1. Striations absent.2. It is involuntary in action3. The muscle fibres are long spindle shaped with POINTED ends.4. The fibres are uninucleated.5. Sarcoplasmic reticulum is poorly developed.6. Sarcomeres absent.7. Less mitochondria and glycogen granules are present.8. Non striated muscle is seen in internal organs.Example: Intestinal muscles.

heir introduction in the early 1970s, in vivo voltammetric methods have provided researchers with a means of studying the dynamics of neurotransmitter release mechanisms in whole animals and brain slices, and more recently in single cells in culture. Using microelectrodes (5–30 µm OD, outside diameter), GENERALLY made of carbon, investigators have studied the signaling dynamics of neurotransmitters and neuromodulators such as dopamine (DA), norepinephrine (NE) and serotonin (5‐HT), and more recently nitric oxide (NO) and glutamate. Unlike the complimentary technique known as microdialysis, in vivo voltammetric methods allow for the very rapid (1–200 Hz) and spatially resolved (5–30 by 30–150 µm as compared to 200–300 µm by 1–4 mm) measurement of the dynamic properties of neurochemicals. However, the routine detection limits of such methods are in the 25–50‐nM range for analytes such as DA, 5‐HT and NO, and these do not rival the picomolar detection limits of methods used to analyze microdialysis samples.These seemingly straightforward methods have been plagued by METHODOLOGICAL problems, primarily dealing with the selective and sensitive measurements of neurotransmitters. Microelectrodes and associated recording techniques must be able to measure and identify selectively the analytes of interest without the use of powerful SEPARATION and quantitation methods such as high‐performance liquid chromatography coupled to electrochemical detection (HPLC/EC). Improvements in microelectrode technologies and recording methods have greatly enhanced the utility of such methods for a variety of studies.The purpose of this chapter is to give readers a general introduction to in vivo voltammetric methods that can be applied to studies of neurotransmitter and neuromodulator signaling dynamics in brain tissues and in cells in culture. We discuss the types of microelectrodes that are now used to record neurochemicals as well as surface modifications that are carried out on these microelectrodes to make them more sensitive and selective for different neurochemicals. The different recording methods and some of their inherent strengths and weaknesses are reviewed as well as the instrumentation currently used to record from microelectrodes for such MEASURES. Finally, we discuss some of the applications of these methods and how they compare with other in vivo recording methods such as microdialysis and fiber optic sensors. This review does not focus on the biological systems that have been studied with these methods and the results of such studies. The major purpose is to give the reader an overview of in vivo voltammetry methods and how they can be used to STUDY neurotransmitter and neuromodulator signaling dynamics in biological systems. Future developments in this field hold great promise for developing a large number of new microelectrodes for detecting a variety of neurochemicals in order to gain an understanding of chemical signaling, which is an integral part of central nervous system (CNS) biology and all biological systems.

s can be classified based on their solubility. Most are water-soluble, MEANING they dissolve in water. In contrast, the fat-soluble vitamins are similar to oil and do not dissolve in water. Fat-soluble vitamins are most abundant in high-fat foods and are much better absorbed into your bloodstream when you eat them with fat. There are four fat-soluble vitamins in the human diet: Vitamin A Vitamin D Vitamin E Vitamin K This article provides a COMPREHENSIVE overview of the fat-soluble vitamins, their health benefits, functions and main DIETARY sources. Vitamin A Vitamin A plays a key role in maintaining your vision. Without it, you would go blind. Types Vitamin A is not a single compound. Rather, it is a group of fat-soluble compounds collectively known as retinoids. The most common dietary form of vitamin A is retinol. Other forms — retinal and retinoic acid — are found in the body, but absent or RARE in foods. Vitamin A2 (3,4-dehydroretinal) is an alternative, less active form found in freshwater FISH (1

is of well-dispersed gold and silver nanoparticles of various size and shapes was achieved at 30 °C by callus and flower extracts of Michelia champaca L. Particularly, gold nanoparticles synthesis by callus extracts was CONSIDERABLY more at 65 °C, having a greater diversity in the geometry and size of nanoparticles. The nanoparticles were characterized by several physico-chemical techniques—UV-visible spectroscopy, TEM, EDX, FT-IR, zeta potential, and DLS measurements. The callus-generated gold and silver nanoparticles exhibit a greater diversity in size and shape than the flower EXTRACT-generated particles. Nanoparticles capped by the functional groups of the phytochemicals in the callus extract could exhibit greater stability. The synthesized AgNPs also showed competence to DEGRADE methylene blue and exhibited anti-bacterial activity against E.coli DH5α. TLC and GCMS analysis resulted in the detection of lignans and triterpenes in the callus extract. The results have demonstrated that callus cultures of Michelia champaca can serve as NOVEL, renewable bio-resources for controlled synthesis of biocompatible nanoparticles.

that my answer will be helpful for youPls mark as BRAINLIEST !!!!!!In many forests, the local population may not be allowed to USE forests in the manner they have been using them for generations.This may sometimes be harmful for the sustainability of forests.When the NOMADIC shepherds were not allowed in the alpine meadows of the great Himalayan National Park to graze their sheep, it had an adverse AFFECT on the growth of grass. Without regular grazing by sheep, the grass grew very tall and then fell over preventing fresh growth.
