Soap is alkaline in nature and is an effective cleansing agent. It is a useful mild antiseptic and can treat heavy metal poisoning.
Chap wanted to see if planting seeds deeper into the soil had an effect on plant height. He took ten containers and planted radish seeds at varying depths. He used the same type of soil, kept the plants in the same location, and gave them each 20 milliliters (mL) of water each day. Then, he measured the height of the sprouts every day for two weeks. What are the independent (test) and dependent (outcome) variables in Chap's experiment?
Answer:
Independent variable: Planting depths of seeds
Dependent variable: plant height
Explanation:
Independent variable in an experiment is the variable that the experimenter changes or manipulates in order to bring about a measurable response. In this experiment involving the planting of radish seeds at varying depths, the DEPTH AT WHICH THE SEEDS ARE PLANTED is the independent variable.
Dependent variable is the variable that is measured in an experiment. It is the variable that responds to the changes made to the independent variable. In this experiment, the HEIGHT of the radish plants measured is the dependent variable.

What groups of organisms are most in danger of extinction?
A. Those with small population
B. Those that migrate or need special habitats
C. Those with large populations that breed quickly
D. Both a and b
Explanation:
D.Both a and B
As organisms with small population and those who migrate and need special habitat are most in danger of extinction.
The group of organisms that are in danger of extinction is those that have small populations and those that migrate or need special habits. So the correct option is D.
What is the extinction of species?
In biology, extinction refers to the extinction or death of a species. Extinction happens when a species' numbers are reduced due to evolutionary changes in its members, such as genetic inbreeding, poor reproduction, and population decline, or due to environmental factors like habitat fragmentation, climate change, natural disasters, and overexploitation of the species for human use.
The majority of species that have ever existed on Earth have gone extinct, but the fossil record indicates five very significant extinctions, known as mass extinction events, each of which resulted in the extinction of enormous numbers of species. The bulk of extinctions, which happen continuously and are described as background extinctions, are separated from these glaring decreases in the variety by the term "mass extinction."
Therefore, the correct option is D.

What is the effect of temperature on ATP,NADPH, and sugars? Will the increase, decrease, or stay the same?
Answer:
1. ATP will increase
2. NADPH will increase
3. Sugar will decrease
Explanation:
Had the same problem
The effect of temperature on these molecules are ;
ATP will increase NADPH will also increase while Sugars will decreaseATP ( Adenosine triphosphate ) is the molecule in cells which stores energy in cells while transferring the energy needed within cells as well. When the temperature of a cell is raised above the required temperature this molecule will also increase in response.
NADPH is an electron donor which is found in organisms, it also provides the reducing power for certain reactions in the organism ( anabolic ) and the gathering of NADPH oxidase. increases as the temperature of the organism increases.
Hence we can conclude that as temperature increases , ATP will increase , NADPH will increase while Sugars will decrease.

how has limiting factors for the ecosystem impacted pythons in the everglades
Answer:
Explanation:
Non-native Burmese pythons have established a breeding population in South Florida and are one of the most concerning invasive species in Everglades National Park. Pythons compete with native wildlife for food, which includes mammals, birds, and other reptiles. Severe mammal declines in Everglades National Park have been linked to Burmese pythons.
The most severe declines in native species have occurred in the remote southernmost regions of Everglades National Park, where pythons have been established the longest. In a 2012 study, populations of raccoons had dropped 99.3 percent, opossums 98.9 percent, and bobcats 87.5 percent since 1997. Marsh rabbits, cottontail rabbits, and foxes effectively disappeared.
The mammals that have declined most significantly have been regularly found in the stomachs of Burmese Pythons removed from Everglades National Park and elsewhere in Florida. Raccoons and opossums often forage for food near the water’s edge, which is a habitat frequented by pythons in search of prey.

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.

Diffusion is the movement of molecules from an area of high concentration of molecules to an area with a ____ concentration.
A. Equal
B. Higher
C. Lower
D. None of the above
Answer:
lower
Explanation:
Diffusion is the movement of molecules from an area of high concentration to an area of lower concentration. So, the correct option is C.
What is diffusion?Diffusion is a type of passive transport, this means that it does not require any kind of external energy for movement of molecules. The difference in concentration in two areas gives rise to a concentration gradient. Where, in one area there is high concentration of molecules and in another, there is low concentration of molecules.
If the molecules move from an area of higher concentration to an area of lower concentration, they are moving along the direction of concentration gradient. This is why no additional energy is required. Diffusion is a type of passive transport where molecules move along a concentration gradient.
This is in contrast to active transport where molecules move against the concentration gradient and therefore require external energy.
Therefore the correct option is C.
