Which of the following organelles provide structure and rigidity to a plant cell?
Answer:
The plant cell is a eukaryotic cell, which exhibits photosynthesis and has membrane-bound, well-defined cell organelles.
Explanation:
Cell walls, intracellular vacuoles, and chloroplasts are the distinctive features of the plant cell, which makes them different from animal’s and other organism’s cells. The cell wall of a plant’s cell is one of the hardest structures made up of cellulose. The primary function of the cell wall is to provide rigidity, structure, and protection to the plant's cell wall. Vacuoles are the large sac in the plant cell, which also play a crucial role in waste disposal, storage, and providing support.

What does light pollution have to do with bird migration?
b.
How would bird migration change after humans disappear?
Answer:
A) Light pollution both attracts and repels migratory birds
In addition to the many hazards that exist in urban areas, cities typically lack the food resources and cover that birds need during migration or when raising their young. ... Darkening skies at night during migration season makes it easier for birds to navigate.
Explanation:
Migration carries high costs in predation and mortality, including from hunting by humans, and is driven primarily by availability of food. It occurs mainly in the northern hemisphere, where birds are funneled on to specific routes by natural barriers such as the Mediterranean Sea or the Caribbean Sea.
Why does frozen water (ice) float on liquid water
Answer:
Because it is a solid that has trapped air with the water molecules in cold temperature thus creating a hard solid.
Explanation:
Because Ice has comparatively less density than water. So, it floats on liquid water.
The oxygen in a molecule of water has a slight negative charge, and the hydrogens have a slight positive charge.
What causes this polarity?
Choose one:
A. The protons spend more time around the oxygen than they do around the hydrogen.
B. The protons spend more time around the hydrogen than they do around the oxygen.
C. The electrons spend more time around the hydrogen than they do around the oxygen.
D. The electrons spend less time around the hydrogen than they do around the oxygen.
Answer:d
Explanation:
The main reason why the oxygen in a water molecule has a slightly negative charge and the hydrogens have a slight positive charge is that electrons spend less time around hydrogen than around oxygen.
The water molecule is a chemical compound made up of two hydrogen molecules and one oxygen molecule (H2O). In chemical compounds, the molecules of the elements share electrons that orbit around their nuclei.
In the case of the water molecule, the electrons shared between oxygen and hydrogen orbit more around the oxygen molecule than in hydrogen molecules.
Therefore, the correct answer is D. because it expresses the situation that causes the oxygen molecule (of a water molecule) to have a slight positive charge and the hydrogen to have a slight negative charge.

a. Independent Variable:
b. Dependent Variable:
2. Weight loss in subjects eating low carbohydrate diets.
a. Independent Variable:
b. Dependent Variable:
3. The number of hours spent studying biology each week and grades earned on biology exams.
a. Independent Variable:
b. Dependent Variable:
Suggest a control group for each of the following experiments.
4. Cancer rates in students who smoke cigarettes are closely monitored over a 5-year period.
Control Group:
5. Weightlifters are given 400 mg of creatine phosphate every day for 90 days. At the end of the 90-day period each participant is evaluated for improvements in strength.
Control Group:
The independent variable produces an effect on the dependent variable, while the control variable produce no change on the results. In the exposed situations, the independent variables are supplemental O₂, low carbohydrate diets, hours spent studying biology. The dependent variables are Endurance of climbers, Weight loss, grades earned on exams. And the control variable might be time.
--------------------------------------
During an experiment, you need to consider all the variables involved.
Independent (manipulated) variable: Refers to all the variables in an experiment that provoke a response in another variable. An independent variable is the one that changes or is controlled and modified to analyze how another variable responds to it. The researcher changes the independent variable to observe its effects on the dependent variable. Usually, the independent variable is represented by the X letter. Dependent variable: Refers to the variable, which response depends on any change in the independent variable. It represents a quantity of something which value depends on how the independent variable is modified. The change in the dependent variable might be proportional or inversely proportional to the change in the manipulated variable. It is usually identified by the letter Y. Controlled variables are kept constant in the control groups and the experimental groups. Unlike the independent variable, the controlled variables do not influence the results. These variables do not affect the response of the dependent variable.
1. Endurance in high altitude mountain climbers with and without the use of supplemental O2.
a. Independent Variable: supplemental O2
b. Dependent Variable: Endurance in mountain climbers
The endurance of climbers will depend on the use of supplemental O₂. If they use supplemental oxygen, they will have more resistance than if they do not use it. Supplemental Oxygen is influencing the climbers´ endurance.
2. Weight loss in subjects eating low carbohydrate diets.
a. Independent Variable: low carbohydrate diets
b. Dependent Variable: Weight loss
Having a low carbohydrate diet will lead the subjects to lose weight. Any change in the quantity of the carbohydrate will affect the individuals' weight.
3. The number of hours spent studying biology each week and grades earned on biology exams.
a. Independent Variable: hours spent studying biology
b. Dependent Variable: grades earned on exams
The more hours students spend studying, the higher grades they get on biology exams. The grades depend on the number of hours used to study and are proportional to this variable.
4. Cancer rates in students who smoke cigarettes are closely monitored over a 5-year period.
Control Group: Time → Five years
Time is constant in all the study groups. Independently of the number of cigarettes smoked, or the frequency in which subjects smoke, all the groups will be analyzed for 5 years, and this time-lapse is constant.
5.Weightlifters are given 400 mg of creatine phosphate every day for 90 days. At the end of the 90-day period each participant is evaluated for improvements in strength.
Control Group: Time → 90 days
Time is constant in all the study groups. Independently of the creatine phosphate mg provided to weightlifters, individuals will be analyzed for 90 days, and this time-lapse is constant.

does soil respond to stimuli?
Answer:
Like all organisms, plants detect and respond to stimuli in their environment. Unlike animals, plants can’t run, fly, or swim toward food or away from danger. They are usually rooted to the soil. Instead, a plant’s primary means of response is to change how it is growing. Plants also don’t have a nervous system to control their responses. Instead, their responses are generally controlled by hormones, which are chemical messenger molecules.

Precipitation, temperature, and vegetation are three factors that are used to classify the six major climate regions. Therefore, option C is correct.
What are climate regions and how are they classified?The description of a region's long-term weather pattern is its climate. The climate is the typical weather for a certain area and time period, typically averaged over a 30-year period. Indeed, it's a typical weather pattern for that area.
The Köppen climate classification classifies climates into five major climate groups, with subgroups within each group determined by seasonal patterns of temperature and precipitation. tropical, arid, temperate, continental, and polar are the five major groups.
Thus, precipitation, temperature, and vegetation are three factors that are used to classify the six major climate regions. Therefore, option C is correct.
