The childhood and early career of Charles Robert Darwin is discussed below.
<h3><u>Explanation</u>:</h3>
Charles Robert Darwin was born on 12 February 1809 in Shrewsbury, Shropshire. He was the fifth of six children of wealthy society doctor and financier Robert Darwin and Susannah Darwin. His grandfathers Erasmus Darwin and Josiah Wedgwood were both prominent abolitionists of the recent times.
Darwin started his career as an apprentice doctor, helping his father treat the poor of Shropshire, before he started to go to the University of Edinburgh Medical School. He found the lectures dull there and in his second year at the university he joined the Plinian Society, a student natural-history group. His father then sent him for a Bachelors of Arts degree which also he couldn't peruse.
After a long fight, he went on his famous voyage on HMS Beagle around the world where he collected his data and then gave his hypothesis in his book named '' On the Origin of Species by means of Natural Selection and Preservation of the Favoured Race in the Struggle for Life''
Many cases seem to occur without an apparent cause, while some may occur due to a genetic ( inherited ) defect, environmental exposure during pregnancy, or a combination or both factors. Syndactyly may also occur as a part of an underlying genetic syndrome and can be found in over 300 different genetic syndromes
An example of incomplete dominance is: A snapdragon flower that is pink as a result of cross-pollination between a red flower and a white flower when neither the white or the red alleles are dominant.<span>

Answer:
1. night blindness
2. Ovule
3. Oxidation
4. Inflorescence
Explanation:
1. Night blindness is odd among haemophilia, colour blindness, thalassaemia because night blindness is not an inheriditary disorder while other three are inheriditary diorder.
2. Ovule is odd among gene, chromosome, allele, ovule because ovule develops into a seed when fertilized and is not a part of genetic material DNA while the other three are part of genetic material.
3. Oxidation is odd among diffusion, imbibition, and osmosis because other belongs to the method of conduction of water and minerals by plants.
4. Inflorescence is odd among seed shape, seed colour and flower position because inflorescence is a group pf flower is flower axis while other belongs to a characteristic of a single or individual flower.
Hence, the correct answer is:
1. night blindness
2. Ovule
3. Oxidation
4. Inflorescence
Answer:
Gut microflora is a combination of many different kinds of bacteria. Out of these, Lactobacillus bacteria, specifically, <em>Lactobacillius acidophilus</em> and <em>Lactobacillus bulgaricus </em>primarily help in the digestion of the milk sugar lactose. Probiotic bacteria in the gut microbiota, primarily, Lactobacillus and Bifidobacterium help in the synthesis of vitamins.
Explanation:
Gut Microbiota:
Gut microbiota are the microorganisms that live inside the gastrointestinal tract and aid in various body functions. Also called commensal flora, many of these help in digestion and biosyntheisis of vitamins.
- Lactobacillus species are a predominant component of gut microbiota. Lactobacillus produces an enzyme called lactase that breaks down lactose sugar in milk.
- Complex sugars in vegetables and fruits are broken down, mostly, by gut microbiota.
- Probiotic bacteria, Lactobacillus and Bifidobacterium species aid the biosynthesis of various vitamins and nutrients such as:
- Vitamin K and most of the water‐soluble B vitamins, such as biotin, cobalamin, folates, nicotinic acid, panthotenic acid, pyridoxine, riboflavin, and thiamine.
