One risk for accessing carbon from the ground is that it may cause soil contamination. Soil when exposed to large amount of gases and other organically decaying materials can absorb these into their make-up. Fossil fuels are extracted from the ground through drilling processes. When the drilling is unsuccessful, pockets created within the soil can create areas for contamination. When soil is contaminated by fossil fuels, it can no longer be use for agricultural purposes.
The definition of vestigial organs are rudimentary structures in humans
that correspond to a functional structure or organ in an ancestor.
Basically the answer is redundant organs present in an organism, which
have been functional in the organism's ancestors.
Answer:
The correct option is Number 1. AaBb x AaBb
Explanation:
Genes can be described as basic hereditary units. The genes are made up of DNA.
A gene carries two alleles for a particular trait. These alleles are present at the same loci in the homologous chromosomes. If the two alleles are similar then they are termed as homozygous e.g AA, BB. If the alleles for a trait are different then they are termed as heterozygous e.g Aa and Bb.
I can certainly see how this is likely to be a science book. With the latest photographic technology scientists have photographed everything from star nebulas, space gases, to exoskeletons of creatures, flowers, sun flares, waves in motion, inside cells, etc. so yes absolutely!
Answer:
The answer is B) arachnoid granulations
Explanation:
Arachnoid Mater and CSF Circulation:
- The arachnoid is the middle layer of the meninges which are the membranes covering the brain.
- The arachnoid is characterized by the spider web like projections that extend between it and the pia mater (outer membrane of the meninges).
- These projections are located in the subarachnoid space (space below the arachnoid). These projections contain the circulating cerebrospinal fluid or CSF.
- The arachnoid extends into the dural sinuses through the arachnoid granulations in which the CSF is filtered and added to the blood for drainage from the brain.
