<span>As a Piagetian, Avery would consider using symbols the highest accomplishment of the sensorimotor period of development.
Piaget developed the theory of various stages of cognitive development. The first stage of cognitive development is the sensorimotor stage (0-2 years of age). The sensorimotor stage of development in turn consists of six sub stages. The most advanced and highest </span>accomplishment of the sensorimotor period of development is when children are able to use symbolic thought to form mental representations of objects. In other words, children at this advanced sub stage are able to mentally visualize objects that are not physically in their field of vision.
The correct answer that would best complete the given statement above is artifacts. Scientists have learned about how early Texans adapted to and changed their environment by looking at artifacts. Artifacts are any objects that are made by human beings, and is being observed for scientific investigation or experiment for archaeological interest.
Social media gives access to communication between people all around the world. People may be afraid of reaction and hold back when giving feedback, meanwhile the feedback is more true to heart on social media, due to the lack of the fear of reaction.
Answer:
RrYy x RrYy
Explanation:
Given
Round (R) allele is dominant over wrinkled allele "r"
and Yellow seed allele (Y) is dominant over green seed allele "y"
If I find a plant with round and yellow seeds and want to determine its genotype, then I will cross it with plant that has heterozygous genotype for both the characteristics i.e "RrYy"
Let us say that the plant I found is heterozygous dominant for both the traits i.e "RrYy"
If RrYy is crossed with another RrYy ,we get -
RY Ry rY ry
RY RRYY RRYy RrYY RrYy
Ry RRYy RRyy RrYy Rryy
rY RrYY RrYy rrYY rrYy
ry RrYy Rryy rrYy rryy
Thus, the possible gnotypes would be
RRYY-1
RRYy-2
RrYY-2
RrYy-4
RRyy- 1
Rryy-2
rrYY-1
rrYy-2
rryy-1
The phenotypic ration for this cross is
. This is a standard cross result between two heterozygous parents.
Answer:
Factor analysis
Explanation:
The student is performing Factor analysis. Factor analysis can be defined as a method of decreasing a large number of variables to small number of factors. This statistical technique can give descriptions of variability among the observed and the unobserved variables. In simple terms, Factor analysis helps in the simplification of data by decreasing the variables in regression.
