occurs for a REDUCTIONAL division and the CHROMOSOME no. in the gamete becomes haploid.This is important to RETAIN the diploid chromosomal number after fertilization of the gametes to form a zygote.If the diploid no.is not retained then the zygote is unviable DUE to an incorrect set of chromosomes which are not associated with the species. Hope this HELPS uh♥️

If MEIOSIS does not occur during production of gamete (sperm cell and egg cell) then the number of chromosomes WOULD INCREASE for EVERY person in every generation. This means that if mother has 10 chromosomes and FATHER has 10 chromosomes then the child (offspring) would have 20 chromosomes.

Louis Pasteur is CREDITED with CONCLUSIVELY disproving the theory of SPONTANEOUS generation with his famous swan-neck flask experiment. He SUBSEQUENTLY proposed that “life only comes from life.”PLS mark as the brainliest ^_^

hey friendExplanation:MODIFICATION of cell theory: Modification of cell theory was DONE by Rudolf VIRCHOW (1855). He proposed the “law of cell lineage” which states that cell originates from pre-existing CELLS. i.e., (OMNIS cellula-e-cellula). It is also called “cell principle” or “cell doctrine”.

It's not all TRUTH SAID in RELIGIOUS WAY . SCIENTIFICALLY its not proved.Explanation:

racteristics or traits of parents are transmitted to their progeny (OFFSPRINGS) through genes present on their CHROMOSOMES during the PROCESS of sexual reproduction. ... Thus, the male and female gamete carries one gene for each characteristic from the gene pairs of parents.Acquired traits are the changes caused in non-reproductive tissues by the environmental factors. For example, darkening of the skin due to prolonged sun exposure which does not have any survival advantage. It does not show any significance in evolution. Therefore, acquired traits are not INHERITED.MEN have a single allele of each gene on the X chromosome, inherited from their mother, and a single allele of each gene on the Y chromosome, from their father. Mitochondrial chromosomes are inherited solely from the mother. Men inherit their mother's mitochondrial genes but do not pass them to their offspring.

An obstetrician-gynecologist, or OB-GYN, has expertise in female reproductive health, pregnancy, and childbirth. Some OB-GYNs offer a wide range of general health services similar to your primary care doctor. Others focus on the MEDICAL care of the female reproductive system.OB-GYNs also PROVIDE routine medical services and preventive screenings. This type of doctor has studied OBSTETRICS and gynecology.The TERM “OB-GYN” can refer to the doctor, an obstetrician-gynecologist, or to the sciences that the doctor SPECIALIZES in, which are obstetrics and gynecology.Thank you plz mark me as the brainliest

m is the vegetative part of a fungus or fungus-like bacterial colony, consisting of a mass of branching, thread-like hyphae. The mass of hyphae is sometimes called shiro, especially within the fairy ring fungi. Fungal colonies composed of mycelium are found in and on soil and many other substrates.Cyanobacteria /saɪˌænoʊbækˈtɪəriə/, also known as Cyanophyta, are a phylum consisting of free-living PHOTOSYNTHETIC bacteria and the endosymbiotic plastids, a sister group to Gloeomargarita, that are present in some eukaryotes. They commonly obtain their energy through oxygenic photosynthesis.Phytophthora is a genus of plant-damaging oomycetes, whose member species are capable of causing ENORMOUS economic LOSSES on crops worldwide, as well as environmental damage in natural ecosystems. The CELL wall of Phytophthora is made up of cellulose. Agrobacterium is a genus of Gram-negative bacteria established by H. J. Conn that uses horizontal gene transfer to cause tumors in PLANTS. Agrobacterium tumefaciens is the most commonly studied species in this genus.

Answer is given below Explanation: you'll need pH strips which are available at your DRUGSTORE or online.process is -- 1). Do not eat or drink for a minimum of two hours before testing.2). Fill your mouth with saliva and then swallow or SPIT it out.3). Fill your mouth with saliva again and then place a SMALL amount of it on a pH strip.4). The strip will change colors based on the acidity/alkalinity of your saliva. The outside of the box of pH strips will have a COLOR chart. Match the color of your pH strip to the color chart to determine your saliva’s pH level. MARK THE ANSWER AS THE BRAINLIEST ANSWER
