Answer:
The options are
A. There will be less soil and dust in the air as construction increases.
B. The atmosphere will improve as more people move to large cities.
C. Making major changes to the atmosphere can be a costly process.
D. It is more important to protect land and water resources than the atmosphere.
The answer is C. Making major changes to the atmosphere can be a costly process.
Explanation:
Making major changes to the atmosphere to the atmosphere to help protect Earth's resources is costly because no one knows the effects of what the changes will have when effected. Another angle is effecting the changes will be a very expensive one as the atmosphere is very large and will be difficult having it happen.
This however validates making major changes to the atmosphere can be a costly process as the right option.

Someone expressing a recessive hair color has _______.
A-1 dominant and 1 recessive allele for hair color
B-2 dominant alleles for hair color
C-2 recessive alleles for hair color
Answer: The answer would be C
Explanation: This is because in order to express a recessive trait one must have no dominant alleles or otherwise the dominant would win out and be expressed instead. For example, if a person had 1 allele for brown hair and 1 for red the brown would win and the same would happen if they had 2 brown hair alleles. Whereas if a person had two alleles for red hair and none for brown, only then would the red trait be expressed. Hope this helped!

Discuss the interconnections of the cardiovascular system with each of the other major body systems introduced. Give specific examples of these interactions and explain their effect on homeostatic balance.
The correct answer to this open question is the following.
The interconnections of the cardiovascular system with each of the other major body systems is of the utmost importance for the health of the human body. The circulatory system's main function is to take blood to all the cells of our body. The instant the heart stops bombing blood to all the cells, organs, glands, and systems, the body stops its vital functions. The Circulatory system has a direct relation to the optimal operation of other systems such as the Respiratory system, the Reproductive system, the Digestive system, the Skeletal system, the Muscular system, the Lymphatic system, the Nervous system, and the Endocrine system.
Use the rose experiment to answer the question. What are the independent and dependent variables?
Answer:
Independent Variable - Amount of Light;
Dependent Variable - Plant Growth;
Controlled Variables - temperature, soil, container, and humidity
Explanation:
Independent Variable - Amount of Light;
Dependent Variable - Plant Growth;
Controlled Variables - temperature, soil, container, and humidity
1. Plants need light for it growth and development. By studying photosynthesis and chlorophyll one can recognizes two factors: measure of light and development of a plant.
The adjustment in light influences the development of a plant. Both the two factors are measurable.
Cause-Independent Variable: measure of light
Impact Dependent Variable: development of plant
2. Plants have stems that become upward and roots that become descending. Become familiar with geotropism.
Answer:
The rose experiment is not a specific experiment but refers to a general example used to explain the concept of variables in an experiment. In this example, let's say we want to study the effect of fertilizer on the growth of roses.
The independent variable in this experiment is the fertilizer. It is the variable that is manipulated or changed by the experimenter. In other words, the experimenter decides how much fertilizer to apply to each group of roses.
The dependent variable in this experiment is the growth of the roses. It is the variable that is being measured and affected by the independent variable. In this case, the experimenter measures the height, number of leaves, and number of flowers for each group of roses, and this data is used to determine if the fertilizer had any effect on the growth of the roses.
Therefore, in the rose experiment, the independent variable is the amount of fertilizer applied to each group of roses, and the dependent variable is the growth of the roses, measured by their height, number of leaves, and number of flowers.
(c) find the longest interval during which no tree-cutting samples occurred. what is the first year that no tree-cutting samples occurred in that interval?
Answer:
Longest interval during which no tree-cutting sample occurred: 9 years (1203 AD - 1212 AD)
First year in that interval: 1203 AD
Explanation:
Lets complete the question first.
Q) A study uses tree rings to determine the year in which a tree was cut. The data is shown in the leaf and stem diagram in the ATTACHMENT.
The three digits number in the left column represents centuries and decades AD. The numbers on the right represents the years.
For example, consider the first input in the diagram
119 | 5 6
which means it represents 2 samples.
1195 AD, 1196 AD.
The longest interval with no tree-cutting samples is found from 1203 AD to 1212 AD.

Can you guys plsssss help me with the questions plsss my assigment is already due plss help me guys!!!!!
Answer:
FOG stands for 'fats, oils and grease'. It is present infood products such as lard, butter, animal fats, vegetable oils, and dairy products.
FOG is prepared during the process of cooking and the washing up processes. When FOG is allowed n sewer pipes it can accumulates inside sewer pipes, so proper disposal method of FOG is required.
Some of the source of FOG and disposal methods are as following:
Cooking oil - Allow the oil to be cooled and place it in a non-recyclable container such as plastic-lined paper containers.
Food Scraps: compost bin can be used to dispose FOG by putting all food scrap into it.
Salad dressing - If little maount of salad dressing is left, use a paper towel to clean it and it will absorb the left residue which can be easily dipose in garbage.
Dairy products such as milk - it can be disposed on-farm or to a proper disposal site otherwise it will affect groundsurface as it contain fat.
Hence, using above methods for disposing FOG will help to save envrionment.
Does compost cause tomato plants to grow faster and taller than artificial fertilizer?

En que consisten las siguientes interacciones bioticas de las relaciones entre organismos: DEPREDACION, PARASITISMO, MUTUALISMO, COOPERACION, SIMBIOSIS, COMPETENCIA, COMENSALISMO, AMENSALISMO
Answer:
La depredación implica la interacción entre un depredador y una presa. El parasitismo ocurre entre 2 organismos diferentes donde un parásito se alimenta del huésped hasta que el huésped es destruido, el mutualismo ocurre es una forma de relación donde ambos organismos de diferentes especies se benefician. La cooperación se produce cuando los organismos trabajan juntos como un equipo para lograr objetivos comunes, como derribar a un gran depredador. En la simbiosis ocurre en diferentes organismos donde ambos se benefician o uno se beneficia o ninguno se beneficia a medida que interactúan. La competencia es la capacidad de un organismo para prosperar en entornos difíciles. El comensalismo es un tipo de relación que ocurre entre organismos donde uno se beneficia y el otro no se ve perjudicado. El amensalismo ocurre entre diferentes especies de organismos en una relación donde uno es destruido y el otro prospera.
Explanation:
La depredación ocurre en la cadena alimentaria donde los organismos más pequeños son consumidos por los más grandes en la cadena alimentaria. El depredador no puede sobrevivir si hay una reducción en la población de presas. Un ejemplo se ve en un león y un ciervo. En el parasitismo, el parásito solo puede sobrevivir cuando el huésped está vivo. Una vez que el huésped muere, el parásito muere con él. El parásito deriva todo su sustento del huésped hasta que el huésped es destruido. Ejemplo de garrapatas en perros. En mutualismo, ambos organismos de diferentes especies en relación obtienen los mismos beneficios. Un ejemplo es el del pájaro picador y la cebra, donde el pájaro picador obtiene su alimento de la cebra y la cebra controla sus plagas. La cooperación se produce entre las mismas especies que trabajan juntas para derribar presas más grandes. Se observa un ejemplo entre las hormigas que derriban una cucaracha. En el caso de la simbiosis, podría ser uno de los 4 tipos: comensalismo, mutualismo, parasitismo o endo / ectosimbiosis. Aquí los organismos de diferentes especies trabajan para lograr objetivos divergentes que a veces se ayudan mutuamente y otras veces se daña. La competencia se ve cuando un organismo posee características especiales que lo ayudan a sobrevivir en ambientes hostiles. Por ejemplo, algunas bacterias poseen cápsulas que les ayudan a almacenar alimentos y sobrevivir largos períodos de deshidratación, así como la presencia de determinantes de resistencia a los antibióticos que pueden ayudarlos a sobrevivir a un ataque de antibióticos. En el comensalismo, una especie vive de otra, pero la otra no sufre daños. Un ejemplo típico son las aves que viven en huecos de árboles. En el amensalismo, la presencia de una especie de organismo inhibe el crecimiento de otro. Un ejemplo es el de las malas hierbas en una granja de maíz. Las malas hierbas ahogan la planta hasta que se destruye para que puedan prosperar.
