Which part of the brain is associated with conscious thought
hichkok12 [17]

Answer:

Cerebral cortex of the Cerebrum

Explanation:

The body directs our body's internal functions. These functions are made possible by four major regions of the brain viz: The Cerebrum, Diencephalon, Cerebellum and Brain stem.

The Cerebrum is the largest brain structure, making up most of the total brain, and a part of the forebrain. The cerebrum's prominent outer portion, the cerebral cortex, not only processes sensory and motor information but also enables CONSCIOUSNESS (our ability to consider ourselves and the outside world), thoughts, emotion, reasoning and memory.

The cerebral cortex is composed of the right and left hemispheres joined by the corpus callosum. Each cerebral hemisphere can be subdivided into four lobes (Frontal, Parietal, Temporal, and Occipital) associated with different functions.

Give two reasons why dna evidence analysis is an imperfect science
Virty [35]

Answer:

DNA samples might be planted and it is possible to synthesize a nucleotide sequence to incriminate a person

Explanation:

In a criminal case, DNA evidence may be considered to be fraudulent because DNA samples might be planted around the crime scene. Moreover, specific genomic profiles of an individual stored in the database can be used to manufacture a DNA sample matching this profile without the necessity to obtain tissues of the person. In consequence, DNA evidence may be considered to be imperfect. Nonetheless, it is important to highlight that DNA evidence is one of the most important modern advances used during criminal trials, and it has proven to be a very useful (and effective) tool available in law enforcement.

Irrigation is an artificial technology that helps to obtain water and thus recover the loss in extensive (wheat) crops.

<h3>What is irrigation?</h3>

Irrigation is a technology based on the artificial supply of water to recover crops from drought conditions.

Genetic modification may also help with drought conditions by inserting into the genome of the target species gene sequences associated with hydric stress (e.g., a protein channel to close stomata at night).

In conclusion, irrigation is an artificial technology that helps to obtain water and thus recover the loss in extensive (wheat) crops.
