As part of an experiment on circadian rhythms, a laboratory rat’s brain has been lesioned. The animal is now falling asleep and

waking up at random times of the day and night. Which part of the brain has most likely been damaged in this experiment?

Answer:the part of the brain that has most likely been damaged in this experiment is the suprachiasmatic nucleus (SCN) found in the hypothalamus of the brain.

Explanation:

circadian rhythms are behavioural changes that respond to light and darkness in an organisms environment. The sleep-inducing wake cycle is a good example of a circadian rhythm. In the experiment, the disruption of the mouse SCN led to development of imbalances in the circadian rhythm of sleep and wake cycle leading to falling asleep and waking up at random times of the day and night. I hope this helps. Thanks

Answer:

Adding a lake near any town will most likely increase rainfall because of the added water, and water vapor levels will also increase. Because of the excess water in the environment, more water will be found in the surrounding atmosphere (the same reason precipitation will increase in the area.)

A expresses dna that has been derived from another species. 2. dna that has been altered to contain genes, or portions of genes,
OlgaM077 [116]
1. A transgenic organism expresses DNA that has been derived from another species. These organisms have altered genomes and are generated in the laboratory for the purposes of research, for example, the "knock-out" mice are tansgenic mice with a particular gene of interest disabled. 
2. Recombinant DNA is the DNA that has been altered to contain genes, or portions of genes, from different organisms. The DNA molecules are formed in the lab using recombination methods to bring together genetic material from multiple sources and therefore creating sequences that are not found in the genome. 
3. Restriction enzymes are found naturally in bacteria and they cut DNA at specific nucleotide sequences. These enzymes are also called restriction endonucleases, they cleave DNA into fragments at or near specific recognition sites called restriction sites. They are found in bacteria and archaea and they serve to provide a defense mechanism against invading viruses.
4. Biotechnology is the use or alteration of organisms, cells, or biological molecules to produce food, drugs, or other goods. Living systems and organisms are used to make or develop products. Biotechnology enhances cellular and biomolecular processes to develop technologies and product for the purposes of improving life and health. 
5. Polymerase chain reaction is a technique that is used to quickly synthesize billions of copiies of a specific segment of DNA.  It is a quick and a very efficient way to generate many copies of DNA.  The process is applicable when there are small quantities of DNA to analyze. The events of PCR involves; separation of DNA strands, addition of primers, use of DNA polymerase to produce second strand of DNA. 
6. In the process known as transformation, bacteria take up pieces of DNA from the surroundings. Bacterial transformation results from the uptake of naked DNA (DNA without associated cells or proteins). Transformation may also occur naturally in some species of bacteria.

The deep palmar veins drain into the radial and ulnar veins; then those veins, along with the anterior crural interosseous vein,
galina1969 [7]

Answer:

Brachial vein.

Explanation:

Veins may be defined as the blood vessels that carries the blood towards the heart. The main function of the vein is to carry the deoxygenated blood into the heart.

Brachial vein is the deep veins that has the name as their arteries occupy. The brachial veins receive their blood from the palmar veins with the interosseous vein. The brachial veins include the ulnar vein, radial vein in upper limb and lower limb consists of popliteal veins.

Thus, the answer is brachial veins.

DerKrebs [107]

Answer:the process of turning from liquid into vapor.

Explanation:

Evaporation is the process by which water changes from a liquid to a gas or vapor. Evaporation is the primary pathway that water moves from the liquid state back into the water cycle as atmospheric water vapor.
