How does high specific heat help aquatic organisms?
Answer:
Explanation:
Due to its high heat capacity, water is used by warm blooded animals to more evenly disperse heat in their bodies; it acts in a similar manner to a car's cooling system, transporting heat from warm places to cool places, causing the body to maintain a more even temperature.
Anna wanted to see what battery lasted the longest. She put each battery into a clock and recorded the time that the clock stopped. She used Duracell, Energizer, Kroger brand, and EverReady. Independent Variable (IV): _Type of clock_____________________________________________ __________________________________________ Dependent Variable (DV): ______________________________________________ Control: _____________________________________________________________ Constants:____________________
Answer:
Independent variable: Type of battery
Dependent variable: Time the clock stopped
Control: None for this experiment
Constants: Same type of clock
Explanation:
Independent variable in an experiment refers to the variable which the experimenter changes or manipulates in order to bring about a measurable response. In this case, the independent variable is the TYPE OF BATTERY USED.
Dependent variable is the variable that responds to changes made to the independent variable. It is the measured variable in an experiment. In this case, the dependent variable is the TIME THE CLOCK STOPPED FOR EACH BATTERY
Control is the group that does not receive the experimental treatment. In this case, NO control group is USED.
Constant is the variable that the experimenter keeps unchanged throughout the experiment for all groups. The constant in this experiment is the CLOCK USED.
Answer:
Independent variable: Type of battery
Dependent variable: Time the clock stopped
Control: None for this experiment
Constants: Same type of clock

Explanation:
Which statement best describes why the population growth rate slows as population size approaches carrying capacity?
O reproduction increases
O predation rates decrease
evolution of traits decreases
competition for resources increases
Answer:
competition for resources increases
Explanation:
When an ecosystem reaches its carrying capacity, competition for scarce resources become more intense.
The result of this is that species will either begin to die, or migrate away from the ecosystem leading to a decrease in population growth
In the human body, is every organ a part of only one organ system? Or are some organs a part of two or more organ systems? A. Every organ is a part of only one organ system, which is necessary because organ systems work independently of one another. B. Every organ is a part of only one organ system, although organ systems often interact with one another. C. Some organs are a part of two or more organ systems. For example, the heart is a part of the circulatory and digestive systems. D.
C
[From ck12.org] "An organ can be part of more than one organ system. For example, the ovaries produce hormones, which makes them a part of the endocrine system; the ovaries also make eggs, which makes them a part of the reproductive system as well."

A developer wants to extend a golf course into a wetland. Outline
environmental arguments you could make against this plan.
Answer:
This is a wrong decision.
Explanation:
This decision is not right because by removing wetland means removal of habitat of millions of organisms living in that wetland. The advantages of wetland is more than golf course. Golf course is only used for sport purpose but wetland has a number of purposes i. e. it provides protection against floods which occurs due to climate change, absorb pollutants and enhances water quality.
A plant has iron deficiency with dry, yellow leaves. How might yellow leaves affect a plant’s ability to photosynthesize?
Answer:
It will photosynthesize at a much slower rate
Explanation:
Chlorophyll is important in the process of photosynthesis. Leaves that aren't green are a physical sign of a lack of chlorophyll.
The earth rotates on its axis in a counterclockwise direction once every 24 hours, deflecting anything traveling long distances on or above the surface. This is known a the Coriolis Effect. What impact could the Coriolis Effect have on weather patterns
Answer:
in the Southern Hemisphere, currents are deflected to the left. As a result, storm systems seem to rotate clockwise. Outside storm systems, the impact of the Coriolis effect helps define regular wind patterns around the globe. As warm air rises near the Equator, for instance, it flows toward the poles.

what makes angiosperm more advance than gymnosperm
Answer& Explanation:
Angiosperm is more advanced due to the mechanism of protection it has since developed as opposed to its predecessor, gymnosperm. Angiosperms could be deemed the inventors of animal-mediated pollination or dispersal, whereas gymnosperms mostly depend on wind-mediated pollination (which is far more of a gamble than animal mediated).
1) Angiosperms seeds are enclosed in fruits, which increases the chances of dispersal by either wind, water, or animals. Animals can eat the fruit and disperse the seeds via feces or by brushing the fruit off of their fur coats new areas of the terrain.
2)The development of flowers. Flowers are especially important because depending on the flower it can attract a set species of animals in order for pollination to occur. That species of animal could only focus on those few flowers and would allow the female part of the flower to receive pollen (produced by the male part of the flower) from all over the place. This theory is also applicable to animal mediated fruit dispersal.
Describe the factors that influence the development and type of soil in a certain area.
Soil research has shown that soil profiles are influenced by five separate, yet interacting, factors: parent material, climate, topography, organisms, and time. Soil scientists call these the factors of soil formation
Answer:
Factors that determine a soil's characteristics include: the type of parent rock from which the soil forms, the climate in the area, the slope of the land, the type and amount of vegetation, and the length of time the rock has been weathering.

Which of the following indicates that an endothermic reaction has occurred?
O Heat is released
O water is formed
O Salt is produced
O Temperature decreases
The following indicates that an endothermic reaction has occurred when temperature decreases, which is in the last option as the endothermic reaction needs heat to carry out the reactions.
What is the significance of the endothermic reaction?There are two types of reactions, such as the reaction that requires heat to form the product, the endothermic reaction, while some of the reactions that release heat are called the exothermic reaction, and the exothermic reactions have more energy at the reactant side than the product side. In the case of a endothermic reaction, the product usually has more energy than the reactants, and the change in free energy here is positive.
Hence, the following indicates that an endothermic reaction has occurred when temperature decreases, which is in the last option as the endothermic reaction needs heat to carry out the reactions.
