Answer:
eagle- chordata phylum
ladybud- Insecta class
scorpian- Arachnida class
lobster- Crustacea class
snail- Mollusca phylum
Explanation:
The organism that contains a notochord at some of its life cycle stage are called chordates and all vertebrates are chordates so eagle comes under phylum Chordata.
Insecta is the largest class of phylum Arthropoda which contains organisms which have jointed legs, exoskeleton and segmented body for example ladybird, playing mantis, etc.
Arachnids are animals which have jointed legs and in this class spider are the largest order which contains scorpions, mites, ticks, etc.
Crustaceans are invertebrates which have hard shell made up of calcium for example lobster, prawn, shrimp, etc.
Mollusks are very large invertebrate phylum which contains a soft segmented body that is usually present inside a shell made up of calcium. for example snails.
Crossing over happens in Meiosis 1 only. In Prophase 1 a cells chromatin (chromatin = chromosomes that have not condensed yet) condense and pair up forming homologous chromosomes (paired = XX (2 chromosomes together)). When this happens segments/ alleles of the chromosomes pairing up swap over. This creates genetic diversity as each chromosome is different, it has parts from its pair. This leaves every chromosome unique and individual.
I hope this helps, sorry some of the vocab is rather technical. By the way I would suggest watching the
'Crash Course: Meiosis' on YouTube, this really helped me when I was learning this topic. :D
Answer:
Number of nucleosomes in 
bp is equal to 
Explanation:
For wounding one nucleosome, total length of DNA required is equal to 
bp
The length of linker DNA in mammals is equal to 
bp
Thus , the total length of DNA that confides between two nucleosome is equal to the sum of wounding length of DNA and the linker length
bp
Thus, in 
bp length of DNA, the total number of nucleosomes is equal to 
Thus, number of nucleosomes in bp is equal to
Rocks are identified primarily by the minerals they contain and by their texture. Each type of rock has a distinctive set of minerals. A rock may be made of grains of all one mineral type, such as quartzite. Much more commonly, rocks are made of a mixture of different minerals. Texture is a description of the size, shape, and arrangement of mineral grains. Are the two samples in figure 2 the same rock type? Do they have the same minerals? The same texture?
Explanation:
Answer:
Due to increment in food chains.
Explanation:
Biodiversity is actually the measure of changes in the ecosystem, genetic levels and various species levels. The sea otters introduced in California over last fifty years, increased the diversity in the ecosystem as well as in species too, thus changing the biodiversity. This was the impact of increase in food web in that particular area, the number of consumers, producers and prey increased thus increasing the biodiversity.
