Take a White Flower and measure it with different soil temperatures and see if it changes colors. And don't forget to record the color and take a picture with different temperatures

Answer:

The correct answer is by conducting scientific experiment.

Explanation:

In the given case, the influence of temperature on the variation in the color of the flower can be examined by conducting an experiment. The range of temperature used will be the independent variable, and the change in flower color will be the dependent variable.

This is the process by which an experiment can be performed in order to witness the outcome of the hypothesis.

Explanation:

During a baseball game, a player’s ball hit into the outfield is modeled by the equation h = –16t2 + 65t. A bird flying across the field follows the path modeled by the equation h = 8t + 20. Let t be the time since the ball is hit and h be the height.

A pea plant with purple flowers (and unknown genotype) is crossed with a pea plant with white flowers. one-half of the offspring

Archy [21]

The genotypes of the parents are Aa (heterozygous) and aa (recessive homozygous).
For example:
If the purple flower is dominant phenotype, then A is a dominant allele for it and Aa is a genotype which will give the purple colour.
In this case, white flower is recessive phenotype with aa genotype.
If we cross Aa x aa
The offspring is going to be Aa Aa aa aa (half purple and half white)

Read each description below regarding innervation of the ANS. Then click and drag each into the appropriate category base on whe

Anna35 [415]

The question is incomplete. Here is the complete question.

Read each description below regarding the dual innervation of the ANS. Then click and drag each into the appropriate category base on whether it is an example of antagonic or cooperative innervation.

The sympathetic division stimulates mucus production by salivary glands while the parasympathetic division stimulates enzyme secretion.

The sympathetic division stimulates am increase in heart rate while the parasympathetic division stimulates a decrease in heart rate.

During sex, the parasympathetic division stimulates arousal while the sympathetic division stimulates orgasm.

The parasympathetic division constricts the pupils while the sympathetic division dilates the pupils.

Antagonistic:

Cooperative:

Answer: Antagonistic: The sympathetic division stimulates am increase in heart rate while the parasympathetic division stimulates a decrease in heart rate; The parasympathetic division constricts the pupils while the sympathetic division dilates the pupils.

Cooperative: The sympathetic division stimulates mucus production by salivary glands while the parasympathetic division stimulates enzyme secretion.; During sex, the parasympathetic division stimulates arousal while the sympathetic division stimulates orgasm.

Explanation: The peripheral nervous system is divided in Somatic Nervous System (SNS) and Autonomic Nervous System (ANS). The first is responsible for sensory input and voluntary motion.

Autonomic Nervous System is divided into Sympathetic and Parasympathetic divisions and is controls the fight-or-flight and rest-and-digest situations. Usually, an organ with sympathetic and parasympathetic innervations have antagonic function, such as the heart rate - one system causes the heart rate to increase while the other stimulates the rate to decrease. However there are cases in which the combination of the 2 systems cause an increase of stimulation, producing similar effects.

Analysing each category above, it is deductable that when the sympathetic stimulates mucus production and parasympathetic, enzyme secretion and when the parasympathetic stimulates arousal and sympathetic, orgasm, in both cases, they have cooperative innervation.

On the other hand, when sympathetic stimulates increase in heart rate and parasympathetic, decrease in the rate, as stated before, and one stimulates constriction of the pupils and the other, dilation of the them, those are examples of having antagonic innervation.

Why is convection more important than conduction in the troposphere? Halp lol

MAVERICK [17]

Answer:

The faster the particles are moving, the more energy they have. Why is convection more important than conduction in the troposphere? The air doesn't conduct heat well so only the first few meters of the troposphere are heated with conduction
