Answer:
The nervous system
Explanation:
The nervous system comprises the central nervous system, consisting of the brain and spinal cord, and the peripheral nervous system, consisting of the cranial, spinal, and peripheral nerves, together with their motor and sensory endings.
I believe the answer is is that it blocks messages within the nervous system, because pain is perceived in the brain through messages sent from the nervous system.
The organisms who do better at surviving and reproducing will pass on more genes than those who don't. So those with better adaptations will survive more to pass on those genes.
True
These factors are all causes of low birth weight in infants:
-Preterm labor
-Chronic health conditions
-Taking certain medicines to treat health conditions, like high blood pressure, epilepsy and blood clots
-Infections
-Problems with the placenta
-Not gaining enough weight during pregnancy
The woman not taking care of herself before giving birth causes low birth weight in infants
Answer:
False. An organism with a dominant allele for a particular form of a trait always exhibits that trait.
Explanation:
According to Mendelian genetics, a dominant allele for a given characteristic will always be expressed in the phenotype, regardless of whether its allelic formula is with both dominant alleles or heterozygous.
In the heterozygous form, the dominant allele is able to avoid the expression of the recessive allele, expressing the phenotype. The recessive allele will only be visible in the genotype when both alleles in the pair are recessive.
In non-Mendelian inheritance, however, there are cases where the dominant allele is expressed in conjunction with another allele, such as co-dominance. In intermediate inheritance different alleles —dominant and recessive— are combined and expressed as a combined characteristic.
