Give an example of connective link. • what is divergent evolution? give example!• state and explain Hardy Weinberg's principles.I Will Mark As a brain list......plz give ANSWER fastly plzzzzzzzzzz ♥♥♥♥ |
|
Answer» ion is a result of divergent evolution and occurs when one species diverges into multiple descendant species. Darwin's finches are an example of this. Convergent evolution occurs when species have different ancestral origins but have developed similar featuresDivergent evolution occurs when two different species share a common ancestor but have different characteristics from one another. This is probably the type of evolution that first comes to mind when the topic of evolution comes up. After all, evolutionary theory teaches us that every form of life on Earth TODAY developed from the first living cells! Over time, the original cells took vastly different paths of development and ultimately created the DIVERSITY of life on Earth—from trees to humans. Each time one ancestral species diverges into multiple descendant species it is called SPECIATION. Speciation is an important result of divergent evolution.Of course, divergent evolution doesn't have to take place on such a grand scale. It can also be as simple as different populations of an organism that have adapted to different environments. Darwin's finches are a good example of this. Darwin's finches are a group of about 15 different species of finches that live on the Galapagos Islands. Each separate species of finch adapted to a different diet, causing variation in their beak shape and/or size. All of them evolved from one species of finch that was a common ancestor.The Hardy–Weinberg principle, also known as the Hardy–Weinberg equilibrium, model, theorem, or law, states that allele and genotype frequencies in a POPULATION will remain constant from generation to generation in the absence of other evolutionary influences.I hope so it will be usefulplease mark it as brainliest |

Important notes of biology ch -why do we fall ill. |
|
Answer» ous diseases are caused by pathogens such as bacteria, viruses, FUNGI and parasites.

How the presense of nuckeus is proved by rutherford,s experiment of gold foil.?please anawer.. |
| Answer» ORD's model of an atom :Ernest RUTHERFORD was interested in knowing how the electrons are arranged within an atom. Rutherford designed an experiment for this. In this experiment, fast moving alpha (α)-particles were made to fall on a thin gold foil.He selected a gold foil because he wanted as thin a layer as possible. This gold foil was about 1000 atoms thick.α-particles are doubly-charged helium IONS. SINCE they have a mass of 4µ, the fast-moving α-particles have a considerable amount of energy. It was expected that α-particles would be deflected by the sub-atomic particles in the gold atoms. Since the α-particles were much heavier than the protons, he did not expect to see large deflections. But, the α-particle scattering experiment gave totally unexpected results .Observations of Rutherford's scattering experiment:As we can see in Fig. 1.Most of the fast moving α-particles passed straight through the gold foil.Some of the α-particles were deflected by the foil by small angles.Surprisingly one out of every 12,000 alpha particles appeared to rebound.I hope this answer is helpful to u...❤❤❤Keep Asking... ✌️✌️✌️✨✨✨If HELP u. Mark my answer as brainliest✨✨✨❤️❤️❤️Thank You❤️❤️❤️. | |

Enjoy 50 point!!Q) WHAT IS NEURO MUSCULAR JUNCTION ?? EXPLAIN NO GOOGLE PLZ |
|
Answer» your answer Neuromuscular junction is a point of contact between the end plate of AXON of a motor NEURON with surface membrane (sarcolemma) of a muscle cell. The knob at the end of terminal branches of motor axon is SEPARATED from the sarcolemma by a NARROW space, the synaptic cleft. The neurotransmitter released from the vesicles of knob of excited motor neuron is acetylcholine which passes through postsynaptic muscle membrane and excitation SPREADS over the whole muscle fibre making it to contract.HOPE IT IS USEFUL |

Why are there small inaccuracies in dna copying? |
|
Answer» l has multiple mechanisms to ENSURE the accuracy of DNA replication. The first mechanism is the use of a faithful polymerase enzyme that can accurately copy long STRETCHES of DNA. The second mechanism would be for the polymerase to catch its own mistakes and correct them. Stem cells have an extra safeguard to preserve the accuracy of their genetic information. DNA is double-stranded. The strands SPLIT apart and serve as templates for new copies. Every time a stem cell replicates its DNA and SPLITS into two cells, the cell that remains a stem cell will keep the same strand of DNA. This strand is called the mother strand or the immortal strand. In this way, the stem cell can preserve the ORIGINAL copy of its DNA.hope this will help you. |

What is meant by menstual cycle |
|
Answer» thly cycle of changes in the ovaries and the lining of the uterus (endometrium), starting with the preparation of an egg for fertilization. When the FOLLICLE of the prepared egg in the ovary breaks, it is released for fertilization and ovulation occurs. Unless pregnancy occurs, the cycle ends with the shedding of part of the endometrium, which is menstruation.
