tion:In cell biology, the nucleus (pl. nuclei; from Latin nucleus or nuculeus, meaning kernel or SEED) is a membrane-bound organelle FOUND in eukaryotic cells. Eukaryotes usually have a single nucleus, but a few cell types, such as mammalian red blood cells, have no nuclei, and a few others including osteoclasts have many.Cell biologyThe animal cellAnimal Cell.svgComponents of a typical animal cell:NucleolusNucleusRibosome (little dots)VesicleRough endoplasmic reticulumGolgi apparatus (or, Golgi body)CytoskeletonSmooth endoplasmic reticulumMitochondrionVacuoleCytosol (fluid that contains organelles, comprising the cytoplasm)LysosomeCentrosomeCell membraneThe cell nucleus contains all of the cell's genome, except for a small fraction of MITOCHONDRIAL DNA, organized as multiple long linear DNA molecules in a complex with a large variety of proteins, such as histones, to form chromosomes. The genes within these chromosomes are structured in such a way to promote cell function. The nucleus maintains the integrity of genes and controls the activities of the cell by regulating GENE expression—the nucleus is, therefore, the control center of the cell. The main structures making up the nucleus are the nuclear envelope, a double membrane that encloses the entire organelle and isolates its contents from the cellular cytoplasm, and the nuclear matrix (which includes the nuclear lamina), a network within the nucleus that adds mechanical support, much like the cytoskeleton, which supports the cell as a whole.Because the nuclear envelope is impermeable to large molecules, nuclear pores are required to regulate nuclear transport of molecules across the envelope. The pores cross both nuclear membranes, providing a channel through which larger molecules must be actively transported by carrier proteins while allowing free movement of small molecules and ions. Movement of large molecules such as proteins and RNA through the pores is required for both gene expression and the maintenance of chromosomes. Although the interior of the nucleus does not contain any membrane-bound subcompartments, its contents are not uniform, and a number of nuclear bodies exist, made up of unique proteins, RNA molecules, and particular parts of the chromosomes. The best-known of these is the nucleolus, which is mainly involved in the assembly of ribosomes. After being produced in the nucleolus, ribosomes are exported to the cytoplasm where they translate mRNA.

So how does the sperm get to the egg? The sperm leave the man's PENIS by ejaculation and are deposited in the vagina high up near the CERVIX (the opening to the womb). The sperm immediately begin swimming and some will find their WAY into the cervix. The sperm then begin their long JOURNEY TOWARDS the egg.please mark it as a brainlist answer

Autotrophic prokaryotes SYNTHESIZE ORGANIC molecules from carbon DIOXIDE. In CONTRAST, heterotrophic prokaryotes obtain carbon from organic compounds. To make the picture more complex, the terms that describe how prokaryotes obtain ENERGY and carbon can be combined.

yes, please follow meExplanation:heterotroph (/ˈhɛtərəˌtroʊf, -ˌtrɒf/;[1] Ancient Greek ἕτερος héteros = "other" plus trophe = "nutrition") is an organism that cannot produce its own food, instead taking nutrition from other sources of organic carbon, mainly plant or animal matter. In the food chain, heterotrophs are primary, secondary and tertiary consumers, but not producers.[2][3] Living organisms that are heterotrophic include all animals and fungi, some bacteria and protists,[4] and many parasitic plants. The term heterotroph arose in microbiology in 1946 as part of a classification of MICROORGANISMS based on their type of nutrition.[5] The term is now used in many fields, such as ecology in describing the food chain.Heterotrophs may be subdivided according to their energy source. If the heterotroph uses chemical energy, it is a chemoheterotroph (e.g., humans and mushrooms). If it uses light for energy, then it is a photoheterotroph (e.g., green non-sulfur bacteria).Heterotrophs represent one of the two mechanisms of nutrition (trophic levels), the other being autotrophs (AUTO = self, troph = nutrition). Autotrophs use energy from sunlight (photoautotrophs) or oxidation of inorganic compounds (lithoautotrophs) to convert inorganic carbon dioxide to organic carbon compounds and energy to sustain their life. Comparing the two in basic TERMS, heterotrophs (such as animals) eat EITHER autotrophs (such as plants) or other heterotrophs, or both.Detritivores are heterotrophs which obtain nutrients by consuming detritus (decomposing plant and animal parts as well as feces).[6] Saprotrophs (also called lysotrophs) are chemoheterotrophs that use extracellular digestion in processing decayed organic matter; the term most often used to describe fungi. The process is most often facilitated through the active transport of such materials through endocytosis within the INTERNAL mycelium and its constituent hyphae.[7]

Green PLANTS have the ability to make their own food. They do this through a process called photosynthesis, which uses a green pigment called chlorophyll. ... Through photosynthesis, the plant uses the STORED energy to convert carbon DIOXIDE (absorbed from the air) and water into glucose, a type of sugar.Control of grasshoppers and locusts has traditionally relied on synthetic insecticides, and for emergency situations this is unlikely to change. However, a growing awareness of the environmental issues ASSOCIATED with acridid control as well as the high costs of emergency control are expanding the demand for biological control. In particular, preventive, integrated control STRATEGIES with early interventions will reduce the financial and environmental costs associated with large-scale plague treatments.Explanation:

A cell's endoplasmic reticulum (ER) contains a network of tubules and flattened sacs. The ER performs multiple FUNCTIONS in both plant and animal cells. Endoplasmic reticulum has TWO major regions: smooth endoplasmic reticulum and ROUGH endoplasmic reticulum. Rough ER contains attached ribosomes while smooth ER does not. VIA the attached ribosomes, rough endoplasmic reticulum synthesizes proteins via the translation process. Rough ER also manufactures membranes. Smooth endoplasmic reticulum serves as a transitional area for transport VESICLES. It also functions in carbohydrate and lipid synthesis. Cholesterol and phospholipids are examples. Rough and smooth ER are typically connected to one another so that the proteins and membranes made by the rough ER can freely move into the smooth ER for transport to other parts of the cell.Explanation:MAKE ME AS BRAINLIEST AND THANKS PLSSS

All these pesticides are highly effective. We export pesticides WORTH Rs 20,000 crore to several countries including the US and these 27 pesticides constitute 70% of it. We don’t think these are harmful enough to be banned,” said R D Shroff, CHAIRMAN of Crop Care FEDERATION of India (CCFI), a body of agrochemical companies.R G Agarwal, chairman of Dhanuka Agritech said by banning these chemicals government will not be able to fight against the locust attack which is haunting border areas of Punjab and Rajasthan.“It’s a death warrant for farmers. If these pesticides are banned crop losses would break the farmers’ back. Many of the banned pesticides are very effecting in FIGHTING locust. The agriculture minister recently ASKED us to help in controlling locust. With these chemicals out of the shelves, how can farmers kill locusts and other deadly pests?” he said.mark as brainlest

All nerves have TWO main functions, these are: Receive signals: Nerves receive signals because they are irritable, meaning that they can respond to a stimulus.Once a stimulus is received by a nerve cell it converts it to a neural IMPULSE which passes along the nerve.As such, they function to transmit impulses from the Central Nervous System to the organs, glands, and muscles. This, in turn, controls the movement of DIFFERENT types of muscles as well as the activity of organs and glands in the BODY. Motor neurons are COMPOSED of multipolar neurons.Hope it helps you mate...☺☺
