The nervous system includes the brain, spinal cord, and a complex network of neurons. This system is responsible for sending, receiving, and interpreting information from all parts of the body. The nervous system monitors and coordinates internal organ function and responds to changes in the external environment.
• Neurons are the basic unit of the nervous system. All cells of the nervous system are comprised of neurons. Neurons contain nerve processes which are "finger-like" projections that extend from the nerve cell body. The nerve processes consist of axons and dendrites which are able to conduct and transmit signals.
• The brain is the control center of the body. One of these furrows, the medial longitudinal fissure, divides the brain into left and right hemispheres. Covering the brain is a protective layer of connective tissue known as the meninges.
• The spinal cord runs down the center of the protective spinal column extending from the neck to the lower back. Spinal cord nerves transmit information from body organs and external stimuli to the brain and send information from the brain to other areas of the body.
DNA is the correct answer but next time put answer choices so that people can better answer your questions. Thanks!
Answer:
The molecules in a solid are more closely packed than those in a gas. Gas molecules are VERY spread apart, which is why we cannot see them.
Explanation:
Store and transmit genetic information: nucleic acid
Are primarily used to store energy: lipids
Help regulate cell processes: proteins
Are used for main source of energy: carbohydrates
Answer:
Both parents have white fur. <em>The only</em> way that this can happen is if their genotypes are both <em>homozygous (bb)</em>. Therefore, both parents pass the (b) allele to every offspring. When you combine two of these alleles, the resulting genotype is <em>(bb);</em> therefore, the resulting offspring have white fur.
Explanation:
A homozygous trait can be described as a trait in which both the alleles for a gene are similar. A heterozygous trait can be described as a trait in which both the alleles of a gene are different. If an allele masks the effect of another allele, it is said to be dominant. the allele that gets suppressed is termed as recessive.
Hence, for a recessive trait to occur both the alleles of a gene should be homozygous recessive.
The punnet square for the above cross is shown below:
b b
b bb bb
b bb bb
