Prader-Willi syndrome
Prader-Willi syndrome is a
congenital disorder that influences many parts of the body. Its distinguishing features are hypogonadism , difficulty in feeding, hypotonia, stunted growth and development.
The onset of this syndrome causes an infected individual to develop an insatiable
appetite which may result in chronic overeating (hyperphagia) and overweight. For
the question given above, Prader-Willi syndrome disorder may be present in this
adolescent.
Answer:
This question is asking to identify the variable in the experimental statement.
The eye chart is the CONTROL VARIABLE
Explanation:
An experiment consists of several variables to look out for in order to achieve any significant result. These variables are independent variables, dependent variables and control variables. Although independent and dependent variables are the major experimental variables, but control variables are also important.
A control variable is the variable that remains constant or unchanged throughout the experiment. Any change to the control variable will affect the dependent and independent variables. In this question, the eye chart is the CONTROL VARIABLE because it remains constant or unchanged. The same eye chart is used for the experiment.
N.B: The distance to the eye chart is the independent variable while the number of letters visible on the line is the dependent variable. Hence, changing the eye chart (control variable) will affect the distance and the number of letters visible.
Answer:
— Eukaryotic gene expression occurs in both the nucleus and cytoplasm.
— Prokaryotic gene expression occurs within the cytoplasm of a cell due to the lack of a defined nucleus
Auxin, which is produced by the apical bud, encourages the growth of apical buds while inhibiting the growth of lateral buds that are located lower on the stem, toward the axillary bud.
<h3>
What does a shoot's apical bud produce?</h3>
Auxin, a hormone produced by the apical bud, travels via the plant's circulatory system (phloem) down the stem and prevents axillary buds from expanding, which would otherwise result in the production of additional side shoots from the plant cells.
<h3>What function does auxin serve?</h3>
Auxin plays a crucial role in controlling plant growth and development by regulating embryonic development, root and stem tropisms, apical dominance,and the transition to blooming..
<h3>What are the four roles that auxins play?</h3>
- Its primary uses are to stimulate shoot growth in culture and to enhance lateral and accidental shoot growth.
- aids in overcoming auxin-induced apical dominance.
- encourage the development of leaves' chloroplasts.
- encourages the mobilization of nutrients and delays leaf senescence.
