Which stage of human development might be MOST concerned with cognitive function?
middle adulthood
adolescence
early adulthood
advanced adulthood
Answer:
Preschoolers, ages three to six, should be at the "preoperational" stage of Piaget's cognitive development theory, meaning they are using their imagery and memory skills. They should be conditioned to learning and memorizing, and their view of the world is normally very self-centered.
Explanation:
so early adulthood think so
The stage of human development that might be most concerned with cognitive function is advanced adulthood. The correct option is D.
What are cognitive functions?Cognitive functions are the psychological functions that are the mental processes that are done to express feelings and actions. They are eight types of cognitive functions.
In advanced adulthood, humans use most of the cognitive functions of the body.
Thus, the correct option is D, advanced adulthood in regard to the stage of human development.

Need help plz!!! Trying to catch up on biology anything can help!!!!
Answer:
See the answer below
Explanation:
The control group in an experimental study is the subject group that is not administered the treatment variable. The control group forms the baseline for comparing the effects produced by the treatment variable on the experimental group.
Thus, in this case, the control group would be the 10 mice that were not exposed to the radio waves.
The independent or the manipulated variable, in this case, is the exposure or otherwise of the mice to the radio waves.
The dependent variable is the actual variable that is going to be measured, otherwise known as the effect variable. In this case, the dependent variable would be the strength of the mice measured by their ability to push the block of wood blocking their food.
Since 8 out 10 mice and 7 out of 10 mice were able to push the wooden block in both the experimental and the control group, Bart's conclusion should reject the hypothesis that the radio waves make mice extra strong.
Bart's experiment can be improved by increasing the number of subject mice in each group. The more the number of subjects, the more the accuracy of the outcome would be.

In a plant species, the allele for dark green leaves (D) is dominant over the allele for light green leaves (d). A plant with Genotype (Dd) is crossed with a plant with genotype (did). What percentage of the offspring are expected to be hybrid for the leaf color trait. A 0% B 25%. C.50%. D 75%
The percentage of the offspring that is expected to be hybrid for the leaf color trait is 50%. The correct option is C.
What are alleles?The trait is caused by a pair of two alleles on the chromosome, and there are two possible outcomes. The dominant allele, which is typically written in capital letters and will control the organism's phenotype even in the presence of the other allele, is the one that has the ability to silence the other allele.
It is used in biology to refer to inherited traits that do not manifest in the phenotype of the individual who possesses them but may do so in their offspring.
Recessive alleles, which are only expressed when they are homozygous, are this other type of allele. Both heterozygous and homozygous genotypes exhibit the dominant allele.
Dd is crossed by dd.
100 / 2 = 50%.
Therefore, the correct option is C.

Which of the following is an example of a heritable characteristic (or inheritable trait) possessed by an animal that will improve its reproductive potential and survivability in its environment?
a. Position of geese flying in V formation
b. Color and shape camouflage of praying mantis
c. Muscle atrophy in aging dogs
d. Male dominance in a pack of wolves
The color and shape camouflage of praying mantises is an example of an heritable trait possessed by an animal that will improve its reproductive ability and survivability in its environment. So, the correct option is (B).
What are Traits?A phenotypic trait is defined as a specific type of a phenotypic characteristic of an organism that can be either inherited or environmentally determined, but usually occurs as a combination of both.
These are characteristics or features of an organism that are expressed by genes and/or influenced by the environment including physical properties of the organism such as hair color, leaf shape, size, etc., and behavioral characteristics such as bird nests.
The color and shape camouflage of praying mantises is an example of an heritable trait. Thus, the correct option is (B).

A scientist wants to determine the best light wavelength for growing plants. He grows plants in four test groups as shown in the table below. What, if anything, was wrong with the experiment?
A. He should only grow one plant in each group.
B. He should only change the wavelength of light for each group.
C. He should add a control group with a CO2 level of zero ppm and a light intensity of zero percent.
D. There is nothing wrong with the experiment.
Answer:
The correct answer is - option B. he should only change the wavelength of light for each group.
Explanation:
In any experiment or research, there should be only one variable that needs to change to see the effect of that variable on the dependent variable and other variables should be constant so there no other variables could influence the result of the experiment.
In this experiment, there is two variable are manipulated that are the different wavelength of light which is desired variable or independent variable in this experiment but CO2 level also changes in each group which should be constant but now it affects the experiment.
