Answer:

The set of pepper plants in the fourth box are the control group

Explanation:

The aim of the experiment is to determine the plant fertilizer that will give the most pepper yield

The number of types of fertilizers used under the study = 3 brands

The number of boxes set up for the experiment = 4 boxes

The number of pepper plants planted in each box = 3 sets

The fertilizers applied to each box = One different type for each of the first three box

The type of fertilizer applied to the fourth box = No fertilizer

The control group is the group to which the effect of the other groups subject to the experimental treatment are compared, and the group not subject to the treatment of the experiment.

Therefore;

The set of pepper plants in the fourth box are the control group.

Why do children worry about their academic achievement? an expectancy-value perspective on elementary students' worries about th
kondaur [170]
Children’s worrying about their academic performance has profound implications for their learning and wellbeing in school. Understanding the contextual and psychological antecedents of students’ worry thus represents an important area of research. Drawing on Eccles and colleagues’ expectancy-value theory and Pekrun’s control-value theory and using data from the Childhood and Beyond Study, we examined the motivational underpinnings of elementary students’ worries about performing poorly in the domains of mathematics and reading (N = 805, grades 3, 4 and 6). With one exception, the analyses confirmed that children’s expectations of success in and valuing of mathematics and reading interacted in predicting children’s worry about these domains. Children’s worry was strongest when they rated their subjective abilities and expected success in mathematics and reading as relatively low but perceived these subjects as valuable. Moderated mediation analyses further suggested that when children’s self-concepts of mathematics and reading ability were low to moderate, students’ perceived parental valuing of their performance in these subjects indirectly positively predicted children’s worry via its positive impact on children’s own subjective valuing of mathematics and reading. Thus, when children perceive high academic performance as potentially difficult to attain, perceived parental valuing might negatively impact their wellbeing in school (by increasing not only their valuing of mathematics and reading, but also their performance-related worrying). Children’s gender, grade level, teacher-rated mathematics and reading aptitude, and prior self-reported worry about mathematics and reading performance were included as control variables in all analyses.

HELP PLS HELP. THE BOOK IS Ceres and Proserpina
Oksi-84 [34.3K]

This question is incomplete because the book is not given, but it can be easily found on the internet.

Explanation

The text deals with the kidnapping of Proserpina, perpetrated by Pluto who wanted her as his wife. This kidnapping was done with the approval of Jupiter (Proserpina's father and Pluto's brother). However, Ceres (Proserpina's mother) did not know anything about this plan, so when her daughter was kidnapped she had a time of depression and anguish, which had negative consequences on agriculture (because Ceres is the goddess of Agriculture). So, Other gods asked Ceres to allow the crops and the fertility of the soils to which she replied that she would if Pluto released her daughter. Once Pluto knew this, he decided to free Proserpina, but he tricked her, making her eat pomegranate seeds (the sacred food of the underworld).

When Proserpina came to her mother she told him that she had eaten these seeds, and her mother was alarmed because this would force Proserpina to be the queen of the underworld and to visit his husband Pluto for half a year, every year. Therefore, the seasons originated because when Proserpina must go to the underworld, her mother becomes sad causing the autumn and winter seasons, and when she returns with her mother they are the spring and summer seasons. So the correct answer is A. Jupiter.
