What is the probability that 5 out of 7 offspring in a monohybrid F2 generation will show the dominant phenotype? Solution Answer: In F2 generation dominant phenotype will be 3/4 and recessive phenotype will be 1/4 5 out of 7 offspring of dominant phenotype = A_B_C_D_E_ffgg= 3/4* 3/4* 3/4* 3/4* 3/4* 1/4 * 1/4 = 243/ 16384 The probability that 5 out of 7 offspring in a monohybrid F2 generation will show the dominant phenotype= 243/16384.

What are the characteristics of life? Solution Answer: Chatacteristics of life: (1) Growth: All living organisms grow, but it is not the defining feature of organisms. It is because non living things, such as a sand dune can grow over time due to accumulation of more sand particles on it. Growth in living organisms are intrinsic (from inside) while those of non living things are extrinsic (from outside). More specifically, intrinsic growth is the defining feature of an organism. In unicellular organisms, growth and reproduction are synonymous. (2) Metabolism: All living organisms metabolise, that is they undergo varieties of biochemical reactions in the body, both to synthesize and degrade macromolecules. The sum total of the catabolic and anabolic processes in the body is called metabolism. It is the defining feature of living organisms. (3) Cellular organisation: All living organisms have cellular architecture, be it a multicelluar organism like humans or unicellular like a bacterium. The cell contains DNA which carries all the necessary informations to make the proteins required for carrying out biological functions. It is also a defining feature of living beings. (4) Reproduction: Living organisms are characterized by the ability to reproduce. But, it is not a defining feature of living organisms. For example, infertile couples, worker bees and mules cannot reproduce but are living. (5) Conciousness: This is another defining feature of living things. Conciousness is the ability of an organism to respond to changes in its environment, more specifically to external stimuli. Human beings are the only organisms to have self conciousness. (6) Energy: Living things take energy for their growth and functions. (7) Homeostasis: It is the process of maintaining a constant balance in the internal environment of the body and plays a crucial role in sustaining life..

Plan how to attack this problem, looking specifically for the line with the most collinear points. Write code to find the line formed by the 3 points. Thank you for any help you are able to provide. Solution The Hough transform is powerful method to detect the edges in the computer visison developed by Paul Hough in 1962, in order to solve this problem we need to create a GUI for the same.

three fossils are found in undisturbed layers of rock, or strata. Fossil A is closest to the earth surface. Given this limited data, what assumptions can you make about these fossils? Solution Ans. A fossil forms when a mud/sand/clay is deposited over a deceased organism overtime. In due course, more and more soil particles are deposited over the previous one, forming layers or strata. So, the recent (newest one) layer of soil remains at the top towards the earth surface, while the oldest layer (in which organism buried) lies at the bottom (farthest deep from earth surface). As a result, the dead organism faces gradually increasing high pressure due to deposition of additional strata. The soft parts decay first, the hard parts (say, bones) being impressed in the highly-compressed soil- thus forming fossils. With the limited information, it can be concluded that fossil A is the newest one (dies most recently) because it is present in the a strata closet to Earth surface..

The brain stem is the link between what two parts? What two structures are part of the upper brain stem? Give the function of each part. What is the limbic system? What three structures are part of the lower brain stem? Give the function of each. Solution 1. The brain stem is the link between the brain and the spinal cord. 2.The upper brain part consists the mid brain and the pons. Functions of mid brain: Also called as the mesencephalon serves as a relay center for visual, auditory and motor information. It regulates the autonomic functions like digestion,heart rate and the respiratory rate. Pons It is the major structure of the upper brain and regulates two important functions. It controls the breathing rate and is also involved in the transmission of the signals to and from other parts of the brain like the cerebrum and the cerebellum.It is involved in the reguation of deep sleep and also sensations like hearing, taste and balance. 3.Limbic system refers to a complex system of nerves and networks in the brain located on both the sides of the thalamus immediately beneath the cerebrum and is concerned with the control of emotions and other related functions related to our instincts and memories..

Since 1942, Ernst Mayr defined \'species\' as populations that can reproduce with one another but not with other populations One problem with this definition is that it applies only to mammals, beds and raffles it does not apply to 90% of all Irving organisms The phylogenetic species concept is based on sexual reproduction descent from common ancestors The author of the article Can Zimmer, argues that the problem of defining microbial species is arbitrary and irrelevant important for public health The author Zimmer points out that there are only two valid definitions of species at least 26 current concepts of species For the sake of convenience, Darwin defined the term species as based on mutual fertility resemblance among individuals genetic mutations Solution 1 . Ootion A Ernst mayr\'s concept of species applies to only those organisms that can sexually reproduce. He did not mention or involve other organisms such as prokaryotes, plants, fungi , bacteria who undergo asexual reproduction. His idea of species was limited to birds, mammals and reptiles ..

On anatomy atlases org or in your text study the process of spermatogenesis. Spermatogenesis spermatozoa primary spermatocyte secondary spermatocyte spermatids immature sperm Solution The process of production of spermatogenesis cells is known as spermatogenesis. The first stage of spermatogenesis is the mitotic division of the diploid spermatogonium ( spermatogonium are the undifferentiated cells in the seminiferous tubules of the testes) to produce two diploid primary spermatocyte. The next stage is the production of two haploid secondaryspermatocyte as result of meiosis I of the primary spermatocyte. The haploid secondary spermatocytes then undergo meiosis II for the production of four haploid spermatids. The spermatids development into mature spermatozoa which is also referred to as sperm cells. Before reaching the epididymus ( the convoluted tube behind the testis), the sperm cells are the immature sperms. Once they reach epididymus, the sperm cells gain motility..

How does it ensure that each daughter cell receives a copy of its chromosomal DNA? It doesn\'t this is a random process There are enough copies of the chromosomal DNA that this will likely happen Each copy of the DNA attaches to the cell membrane. As the cell elongates the chromosomes move apart from one another, ensuring that one copy is in each daughter cell.
