<span>A solution is hypertonic to a cell if it has a higher solute (dissolved substance) concentration than the cell does. As a result, it also has a lower concentration of water than the cell does. Cell membranes and plant cell walls are semipermeable barriers, which means that certain molecules can diffuse through them, while other molecules can not.</span>
Answer:
Explanation:
# Boys are four times more likely to be diagnosed with autism than girls.
# Most children were still being diagnosed after age 4, though autism can be reliably diagnosed as early as age 2.
# 31% of children with ASD have an intellectual disability (intelligence quotient [IQ] <70), 25% are in the borderline range (IQ 71–85), and 44% have IQ scores in the average to above average range (i.e., IQ >85).
# Autism affects all ethnic and socioeconomic groups.
# Minority groups tend to be diagnosed later and less often.
# Early intervention affords the best opportunity to support healthy development and deliver benefits across the lifespan.
# There is no medical detection for autism.
Answer:
The chloroplast
The chloroplast is involved in both stages of photosynthesis. The light reactions take place in the thylakoid. There, water (H2O) is oxidized, and oxygen (O2) is released.
Explanation:
The answer is D. In a
geological era, when the plants and animals
in the then environment die, they get buried
in sediments. These sediments are covered
by other sediments of another geological
time within which are the remains of dead species
of the then geological era. These sediments from different geological times have different properties hence
form visible strata that can be studied to identify the kind of environment in the then geological time. Their
fossils can also be studied to identify
the kind of species that roamed the earth during the time.
