There should be 14 chromosomes in the gamete as the gamete mother cells undergo meiosis or reduction devision to form haploid gametes having n no. Of chromosome . During fertilisation, when two gametes fuse the chromosome becomes 2n or the cell becomes diploid .
<span>Metabolism is the
chemical reactions that take place inside a living organism. The reaction
occurs in the cells. Digestion can be
the best association to metabolism. The metabolic system recognizes which
substances can be nutritious or poisonous. In order to complete this process,
water is needed. The chemicals are
dissolved in water and transported. Without water, no reaction can take place.</span>
Metabolism is considered
as the set of life-sustaining chemical reactions within the living organism’s
body cells.
Answer:
Involuntary motor commands to the erector spinae: it is the tegmentum
Houses the superior colliculi: it is the tectum
Site of neurons that produce dopamine: it is the substantia nigra
Motor axons from primary motor cortex to spinal cord: cerebral peduncles
Explanation:
The tegmentum is an area of the brainstem involved in unconscious perception and reflexive commands. The tectum is localized in front of the tegmentum, which has been involved in motor responses such as, for example, walking, swimming (in fish), etc. The substantia nigra is a region of the ventral midbrain with a high concentration of neuromelanin in its dopaminergic neurons. The substantia nigra has been associated with Parkinson's and Huntington's diseases. Finally, the cerebral peduncles are two structures on each side of the brainstem that attach this component of the brain with the cerebrum. The cerebral peduncles have been involved with motor skills, balance and posture control.
Psychophiles are bacteria can grow and survive in really low temperatures. These organism are adapted to freezing temperatures by producing antifreeze proteins that protect the organisms from vetrification and dessication. Examples of psychophilic bacteria that can contaminate food include Aeromonas spp and Yersinia spp
Answer: Sinusoid capillaries
