As babies they may reach growth and development milestones later than
other children do. These may include rolling over, sitting,
standing, walking, and talking. As children in this age group,
health problems and developmental disabilities can lead to
behavior problems. For example, a child may develop oppositional
defiant disorder which is a disorder in a child marked by defiant and disobedient behavior to authority figures.
They may get this disorder because he or
she does not communicate well or understand others' expectations. As teens puberty starts
at about the same ages for teens with Down syndrome as for other teens. <span>They may face social difficulties and vulnerabilities <em /><em />such as abuse, injury, and other types of harm. They may also have a
hard time handling strong emotions and feelings. Sometimes these
struggles can lead to metal health problems,
especially </span>depression which could lead to self-harm or even suicide. As adults men with Down syndrome most often are sterile and
cannot father children. Many women with Down syndrome can have children, and
they usually have early menopause which is <span>a natural decline in reproductive hormones when a woman reaches her 40s or 50s but in this case it would usually happen early in Down Syndrome women.
Hope this helps you out on your report is there anything else you want me too help you with? :)

Answer:
The plasma membrane is selectively permeable
Explanation:
hydrophobic molecules and small polar molecules can diffuse through the lipid layer, but ions and large polar molecules cannot. Integral membrane proteins enable ions and large polar molecules to pass through the membrane by passive or active transport.
Answer:
B. there were more double crossovers in the progeny than would be expected based on probability
Explanation:
Crossing over or recombination can be defined as the exchange of genetic material between homologous chromosomes during meiosis. Moreover, the coefficient of coincidence is the number of double recombinants found in the progeny. The coefficient of coincidence can be estimated by the following equation:
Coefficient of coincidence (COC) = ADRF / EDRF
where ADRF = Actual Double Recombinant Frequency
and EDRF = Expected Double Recombinant Frequency
In the case above described, ADFR is higher than EDRF, and therefore COC will be higher than 1.
Answer:
Linked Genes Violate the Law of Independent Assortment. Although all of Mendel's pea characteristics behaved according to the law of independent assortment, we now know that some allele combinations are not inherited independently of each other.
