Reverse osmosis is active transport or passive?? |
| Answer» Reverse osmosis\xa0occurs when water is moved across the membrane against the concentration gradient, from lower concentration to higher concentration.\xa0Reverse osmosis\xa0is an\xa0active\xa0process. Osmosis\xa0is the process in which water molecules move from a region of higher water potential to a region of lower potential down a water potential gradient across a partially permeable membrane, so little energy is required to carry out this process, thus it is a\xa0form\xa0or\xa0passive transport. | |

By looking at a plant externally can u tell whether the plant is c3 or c4 |
| Answer» One cannot distinguish whether a plant is C3 or C4 by observing its leaves and other morphological features externally. Unlike C3plants, the leaves of C4 plants have a special anatomy called Kranz anatomy and this difference can only be observed at the cellular level. For example, although wheat and maize are grasses, wheat is a C3 plant, while maize is a C4 plant. | |

Explain Life cycle of Alage |
| Answer» The green algae exhibits three types of life cycles:(i) Haplontic (ii) Diplontic (iii) Diplohaplontic(i) Haplontic :(a) The dominant phase is haploid, while diploid stage is present only in the form of zygote or zygospores.(b) Meiosis occur at the time of zygote germination e.g. Chlamydomonas, Ulothrix, Spirogyra.(ii) Diplontic:(a) The dominant phase in the life cycle is diploid.(b) Gametes are produced through meiosis.© They represent haploid phase.(d) The diploid phase is restored as a result of fusion of gametes, e.g. Caulerpa.(iii) Diplohaplointic:(a) In this life cycle, both diploid and haploid phase are well developed and multicellular.(b) They are respectively called sporophyte and gametophyte.© The haploid gametophyte produces haploid gametes, which fuse into diploid zygote.(d) The diploid zygote grow into a diploid sporophyte. The latter produce haploid spores or meiospores through meiosis.(E)New gametophytes are produced by the germination of meiospores.(f) Thus, this cycle exhibits alternation of generation, between haploid and diploid multicellular generations. | |

What is pleura ? |
|
Answer» Pleura is a structure that covers up the lungs. It has two layers which is been separated by the pleura cavity. Pleura cavity is also called a pleura space, which is mainly the thin and fluid-filled space present between the two pulmonary pleura. Mainly the visceral pleura receives all its blood supply from the bronchial circulation, which is also a supplier of the lungs. The visceral pleura which is responsible for covering the lungs receives the innervations from the autonomic nervous system. Pleura is a structure that covers up the lungs.

List out the events in mitotic cell divisionPlz ans fast ? |
|
Answer» Phases of Cell cycleHuman cell divides once in approximately 24 hours, which may vary in different organisms. In yeasts it takes about 90 minutes to complete the cell division process.Cell cycle is divided into two basic phases-\tInterphase– it is the phase between two successive M phases. Interphase lasts for 95% of a cell cycle. This phase is called as resting phase but during this period the cells prepare itself for nuclear division by cell growth.\tM Phase– when the actual cell division or mitosis occurs. It starts with karyokinesis (nuclear division) or duplication of chromosome and end with cytokinesis or division of cell matrix (cytoplasm division).The interphase is divided into three further phases:\tG1 phase represents the interval between mitosis and initiation of DNA replication. Cell is continuously active and grows in size.Click on the given link for more:Cell Cycle and Cell Division class 11 Notes Biology ... Right before prophase, the cell spends most of its life in the interphase, where preparations are made before the beginning of mitosis (the DNA is copied). However, since the actual process involves the division of the nucleus, prophase is technically the first stage of this process.The different stages of mitosis occurring during\xa0cell division\xa0are given as follows-InterphaseBefore entering mitosis, a cell spends a period of its growth under interphase. It undergoes the following phases when in interphase:\tG1 Phase:\xa0This is the period before the synthesis of DNA.\tS Phase:\xa0This is the phase during which DNA synthesis takes place.\tG2 Phase:\xa0This is the phase between the end of DNA synthesis and the beginning of prophase. |

Describe the phenomena of release and transport of a neurotransmitter....... I need a short answer |
| Answer» A nerve impulse is transmitted from one neuron to another through junctions called synapses. A synapse is formed by the membranes of a pre-synaptic neuron, which may or may not be separated by a gap called synaptic cleft. There are two types of synapses, namely, electrical synapses and chemical synapses. At a chemical synapse, the membranes of the pre-post synaptic neurons are separated by a fluid-filled space called synaptic cleft. Chemicals called neurotransmitters are involved in the transmission of impulses at these synapses. The axon terminals contain vesicles filled with these neurotransmitters. When an impulse (action potential) arrives at the axon terminal, it stimulates the movement of the synaptic vesicles towards the membrane where they fuse with the plasma membrane and release their neurotransmitters in the synaptic cleft. The releases neurotransmitters bind to their specific receptors, present on the post-synaptic membrane. This binding opens ion channels allowing the entry of ions which can generate a new potential in the postsynaptic neuron. | |

Give an account of the asexual reproduction by spores in algae. |
|
Answer» Thank u ? Algae reproduce asexually by a variety of spores such as ,1) Zoospores : these are flagelated , often with an eyespot. Normally these are formed under favourable conditions e.g. Chlamydomonas.In Vaucheria, compound zoospores called synzoospore are formed.2) Aplanospores : these are non motile thin walled zoospores , formed by cleavage of protoplasts within a cell. They are formed under unfavourable conditions e.g. Ulothrix3) Akinetes : these are formed under unfavourable conditions as method of perinnation. They are thick walled and non motile. On release they form new thalli e.g. Anabaena4) Hypnospores: these are thick walled aplanospores and are formed during unfavourable conditions. Under prolonged unfavourable conditions the protoplasm of Hypnospores divides to make cysts e.g. Chlamydomonas nivalis.5) Tetraspores : these are haploid thin walled non motile spores formed after reduction division in diploid tetrasporangia e.g. members of Rhodophyceae and Phaeophceae.6) Autospores : these are similar to the parent cell. In Chlorella and Scenedesmus autospores acquire all characteristics of parent cells before their discharge from sporangium. |
