Write a monologue on evolution of a man to perform a stage show on the theatre day in your school. |
|
Answer» umentation identifying the stages of “man evolution” has to assume that man evolved rather than having been created. We believe that evidence has failed to support the evolution from APE to man or any other type of macroevolution. The Cambrian explosion and the complete absence of transitional fossils testify against evolution. The FOSSIL record shows all LIFE forms APPEARING fully formed and not changing during their tenure on earth, except for extinctions. This information, and the recent finding that human DNA is losing its VITALITY by developing genetic disorders supports devolution, the opposite of evolution. pls mark brainliest |

Answer» Evidence of common descent of living organisms has been discovered by scientists researching in a variety of disciplines over many decades, demonstrating that all life on Earth comes from a single ancestor. This forms an important part of the evidence on which evolutionary theory rests, demonstrates that evolution does occur, and illustrates the processes that created Earth's biodiversity. It supports the modern evolutionary synthesis—the current scientific theory that explains how and why life changes over time. Evolutionary biologists document evidence of common descent, all the way back to the last universal common ancestor, by developing testable predictions, testing hypotheses, and constructing theories that illustrate and describe its causes.Comparison of the DNA genetic sequences of organisms has revealed that organisms that are phylogenetically close have a higher degree of DNA sequence similarity than organisms that are phylogenetically distant. Genetic fragments such as pseudogenes, regions of DNA that are orthologous to a gene in a related organism, but are no longer ACTIVE and appear to be undergoing a steady process of degeneration from cumulative mutations support common descent alongside the universal biochemical organization and molecular variance patterns found in all organisms. Additional genetic information conclusively supports the relatedness of life and has allowed scientists (since the discovery of DNA) to develop phylogenetic trees: a construction of organisms evolutionary relatedness. It has also led to the development of molecular clock techniques to date taxon divergence times and to calibrate these with the fossil record.Fossils are important for estimating when various lineages developed in geologic time. As fossilization is an uncommon occurrence, usually requiring HARD body parts and death near a site where sediments are being deposited, the fossil record only provides sparse and intermittent information about the evolution of life. Evidence of organisms prior to the development of hard body parts such as shells, bones and teeth is especially scarce, but exists in the FORM of ancient microfossils, as well as impressions of various soft-bodied organisms. The comparative study of the anatomy of groups of animals shows structural features that are fundamentally similar (homologous), demonstrating phylogenetic and ancestral relationships with other organisms, most especially when compared with fossils of ancient extinct organisms. Vestigial structures and comparisons in embryonic development are largely a contributing factor in anatomical resemblance in concordance with common descent. Since metabolic processes do not leave fossils, research into the evolution of the basic cellular processes is done largely by comparison of EXISTING organisms' PHYSIOLOGY and biochemistry. Many lineages diverged at different stages of development, so it is possible to determine when certain metabolic processes appeared by comparing the traits of the descendants of a common ancestor. |

What variations generally have you observed in the species of cow? |
|
Answer» eed gives a slightly different milk product that varies in nutrient content (i.e. protein and vitamins). You are probably most familiar with the Holstein-Friesian (BLACK and white) dairy cow. It is the most popular among dairy farmers because it produces more milk than the other breeds. Although it would make sense for farmers to milk herds of pure Holsteins since they give the most milk, some farmers mix their breeds because cows that are slightly mixed tend to be stronger than pure Holsteins. This hybridization is what accounts for the difference in appearance that you may see in a herd of dairy cows.What else should you know about cows? Just like with humans, there are different names given to cows depending on their sex and STAGE in life. For example, a female cow younger than 3 years old that has not had a baby is termed a heifer; a male cow is called a bull; and a castrated male is a STEER. So a dairy cow is a female that has given BIRTH to a baby. That baby is called a calf.Moo Wonder icon Moo Wonders A Holstein's spots are like fingerprints- no two cows have the EXACT same pattern of spots.Cow's provide 90% of the world's milk supply.The average mature dairy cow weighs approximately 1,500 pounds. How does that compare to your own weight percentage wise? |

Give reason of the following-: |
|
Answer» eristematic cells have to divide very quickly, they have a prominent nucleus and lack vacuole.Schlerchaymatous cells have a cementing material called as pectin AROUND their cell wall which fills up the intercellular spaces between them. That is why they lack intercellular spaces.Since branches are made up of collenchyma cells, it makes them flexible and elastic an for this reason they move freely in high WINDS and bend easily.The husk of coconut is made up if schlerenchyma fibres which makes it difficult to pull the husk out of coconut.The WATER plants have aerenchyma cells which exist in forms of rings and have a hole in centre which makes them less dense and allows the leaves to float.HOPE IT HELPS U AND PLS MARK IT THE BRAINLIEST ANSWER AND DO FOLLOW ME FOR MORE SUCH ANSWERS :) |

in cactus both leaves and stems are modified to perform different functions .name the modification and identify their functions |
| Answer» TION:(i) ENTIRE Leaf is Modified into Tendril, e.g., Lathyrus aphaca (wild pea) (Fig. 4.19). (ii) Upper Leaflets Modified into Tendrils, e.g, Pisum sativum (pea) (Fig. 4.20), Lathyrus odoratus (sweet pea). (iii) Terminal leaflets Modified into Tendrils, e.g., Naravelia (Fig. 4.21). Leaf Tendrils (iv) Leaf Tip Modified into Tendril, e.g., Gloriosa (Glory lily) (Fig. 4.22). (v) Petiole Modified into Tendril, e.g., Clematis (Fig. 4.23). (vi) Stipule Modified into Tendril, e.g., Smilax (Fig. 4.24). Leaf Tendrils 3. Leaf-spines: Leaves of certain plants become wholly or partially modified for defensive purpose into sharp, pointed STRUCTURES known as spines. Thus, in prickly pear (Opuntia; fig. 4.25) the minute leaves of the axillary bud are modified into spines. The leaf-apex in date-palm, dagger plant (Yucca) etc., is so modified, while in plants like prickly or Mexican poppy (Argemone), Amercian aloe (Agave), Indian aloe (Aloe), etc., spines develop on the margin as well as at the apex. In barberry the leaf itself becomes modified into a spine; while the leaves of the axillary bud are normal. 4. Scale-leaves: Typically these are thin, dry, stalkless, membranous structures, usually brownish in colour or sometimes colourless. Their function is to protect the axillary bud that they bear in their axil. Sometimes scale-leaves are thick and fleshy, as in/onion; then their function is to store up water and food. Scale-leaves are common in PARASITES, saprophytes, underground stems, etc. They are also found in Casuarina, Asparagus etc. Leaf Tendrils 5. Leaflet Hooks: In Bignonia unguiscati the three terminal leaflets of leaf get modified into claw like hooks which help in climbing (Fig. 4.29). 6. Leaf Roots: In case of Salvinia three leaves are present at one node. Out of these two leaves are normal and third GETS modified into adventitious roots which help in floating over the surface of water (Fig. 4.30). | |
