Answer:
Typically, Copper is used for wires in electric circuits.
Before making a decision as to whether you should throw away your baking soda toothpaste or not, you should first determine the basal risk of developing frabjuous cell basocarcinoma. If the chances of developing this are already negligible, then a 700% increase is no cause for alarm.
Answer:
All early vertebrate embryos develop tails and gill slits, and therefore this type of anatomical evidence supports common ancestry
Explanation:
Embryology is a discipline that studies the structural/anatomical features and development of embryos. Embryos are a fundamental piece of evidence to support common ancestry among vertebrates because there are homologous structural features that can only be observed during the first stages of vertebrate development. For example, all vertebrate embryos (e.g., fish, chicken and human embryos), develop tails and gill slits during their first stages of embryo development. In consequence, embryology provides evidence for evolution of vertebrates.
The reproductive system is different from other body systems in that the reproductive system functions in the survival of a species while all other body systems function to ensure the survival of the individual.
Answer:
Option D, Number of limbs
Explanation:
Options for the question
a. Birth weight
b. Hair color
c. Number of offspring
d. Number of limbs
Solution
Variation within a species is caused due to genetic differences governed by varying allele frequencies and duet to environmental factors that somewhere effect the expression of the genetic potentials thereby causing phenotypic variation.
Number of limbs is a physical characteristics, very unlikely governed by genetic variation. While factors such as hair color (grey, black, white etc.), height (tall, short, medium) etc. are governed by genetic variation as a result of which they have several phenotypic variations.
Hence, option D is correct
