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?

Answers

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

Answers

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.

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

Answers

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.

Answers

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 decrease

ATP (  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.

what makes angiosperm more advance than gymnosperm​

Answers

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.

Flowering plants mature more quickly than gymnosperms, and produce greater numbers of seeds. The woody tissues of angiosperms are also more complex and specialized. Their seeds are enclosed in a fruit for easy dispersal by wind, water, or animals.

true or false? diffusion is a result of the random movement of particals

Answers

The kinetic energy of the molecules results in random motion, causing diffusion. In simple diffusion, this process proceeds without the aid of a transport protein. it is the random motion of the molecules that causes them to move from an area of high concentration to an area with a lower concentration. The rate of this movement is a function of temperature, viscosity of the fluid and the size (mass) of the particles. Diffusion explains the net flux of molecules from a region of higher concentration to one of lower concentration. However, diffusion can still occur in the absence of a concentration gradient. Diffusion requires energy input from the cell. ... Only water can diffuse across a cell membrane. Molecules move from areas of high concentration to areas of low concentration. - Passive transport is the diffusion of substances across a membrane. - Facilitated diffusion is the process of spontaneous passive transport of molecules or ions across a cell's membrane via specific proteins. Concentration gradient, size of the particles that are diffusing, and temperature Examples of diffusion in living organisms

Oxygen and carbon dioxide, dissolved in water, are exchanged by diffusion in the lungs: oxygen moves down a concentration gradient from the air in the alveoli to the blood. carbon dioxide moves down a concentration gradient from the blood to the air in the alveoli. What determines the direction of any diffusion process? The relative concentration of the substance in different areas determines the direction of diffusion.

Cellular respiration uses one glucose molecule to produce a total of 38 ATPs (option B).

What is cellular respiration?

Cellular respiration is the process by which cells obtain chemical energy by the consumption of oxygen and the release of carbon dioxide.

Cellular respiration occurs in three processes namely;

Glycolysis; this is the cellular degradation of the simple sugar glucose to yield pyruvic acid, and ATP as an energy source.

Krebs cycle; this is a series of enzymatic reactions that occurs in all aerobic organisms; it involves the oxidative metabolism of acetyl units, and serves as the main source of cellular energy.

Electron transport chain; this is a series of electron transfer that results in the synthesis of large amount of energy.

In total, the overall process of cellular respiration results in the formation of 38ATPs.
