Answer:
Variables are given a special name that only applies to experimental investigations. One is called the dependent variable and the other the independent variable. The independent variable is the variable the experimenter manipulates or changes, and is assumed to have a direct effect on the dependent variable.
Explanation:
Answer:
The independent variable is the factor that doesn't rely / change based on another variable. Usually there is an independent, dependent, and constant variable. The dependent variable's "results" and values rely on the independent value.
For example if tomatos were to be grown the independent variable is the type of light the tomato plant is grown under. The dependent variable would be the rate of the growth of the tomato plant. (It relies on the type of light, the independent variable)

HOW DO THE OCEANS CURRENTS AFFECT CLIMATE
Answer:
Explanation:
Ocean currents act much like a conveyor belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics. Thus, ocean currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth's surface.
Scientific classification systems have changed throughout time. In the past, the classification of organisms was based mostly on shared physical characteristics. What forms the basis of the modern classification system
Answer:
Modern scientists base their classifications mainly on molecular similarities. They group together organisms that have similar proteins and DNA. Molecular similarities show that organisms are related
Organisms are classified as producers or consumers according to the way they *
(1) obtain energy
(2) release wastes
(3) produce offspring
(4) move from place to place
What factors influence the survival of Kangaroos in its natural habitat?
Answer:
Kangaroos from desert and semi-arid environments have adapted to drier conditions and have several features that help them deal with the lack of water. Kangaroos need very little water to survive. Kangaroos hop over large distances to find food and water. Hopping is a fast, energy efficient way to travel. Kangaroos need very little water to survive and are capable of going for months without drinking at all. The kangaroo usually rests in the shade during the day and comes out to eat in the late afternoon and night when its much cooler. It eats mostly grass. It needs very little water to survive.

6. Plates slide past one another at ________________________ plate boundaries.
Answer: When oceanic or continental plates slide past each other in opposite directions, or move in the same direction but at different speeds, a transform fault boundary is formed.
Explanation: No new crust is created or subducted, and no volcanoes form, but earthquakes occur along the fault. The transform fault boundaries connect spreading centers and subduction zones, which are the other elements of the jigsaw puzzle of the Earth’s plates.

Two humans mate who are heterozygous for earlobe shape where attached earlobes (A) are dominant to free earlobes (a), and earwax quality where dry earwax (e) is recessive to wet earwax (E ). What is the probability that their first child will have dry earwax and attached earlobes
Answer:
3/16
Explanation:
This question involves two different genes coding for earlobe shape and earwax quality. The alleles for attached earlobes (A) and wet earwax (E) are dominant over the alleles for free earlobes (a) and dry earwax (e).
According to this question, two humans mate who are heterozygous for both genes i.e. AaEe × AeEe. Each parent will produce the following gametes: AE, Ae, aE, ae.
Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:
* Attached earlobe, wet earwax (A_E_) = 9/16
* Attached earlobe, dry earwax (A_ee) = 3/16
* Free earlobe, wet earwax (aaE_) = 3/16
* Free earlobe, dry earwax (aaee) = 1/16
Hence, the probability of these parents having their first child with dry earwax (ee) and attached earlobes (A_) i.e. genotype A_ee is 3/16.
Reproductive isolation occurs when
A- some catastrophic event greatly reduces the size of the population
B- The gene pool of different populations have become very diversified
C-members of different populations can no longer meet successfully
D-small numbers of individual moves and starts in new population
Answer:
The correct answer is - C. members of different populations can no longer meet successfully.
Explanation:
Reproductive isolation is the process that occurs when two or more species or populations are not able to interbreed. The mechanisms or properties that are used to preventing individuals of separate species from mating called Reproductive isolation mechanisms.
The different barriers can cause this reproductive isolation such as different mating seasons. These barriers could be behavioral or temporal or ecological isolations.
5. On the rock shoreline, how was biodiversity affected by the removal of starfish?
Answer:
When the starfish have been removed experimentally, the mussel populations have expanded rapidly and covered the rocky intertidal shores so exclusively that other species cannot establish themselves.
Explanation:
Explain the role of the cell cycle in the production of tissues.
Answer:
the cell cycle allows multicellular organisms to grow and divide a single-celled organism to reproduce
The fundamental function of the cell cycle is to duplicate accurately the vast amount of DNA in the chromosomes and then segregate the copies precisely into two genetically identical daughter cells. The collection of cells gives rise to the synthesis of tissues.
What do you mean by Cell cycle?Cell cycle may be defined as the entire sequence of events happening from the termination of one nuclear division to the beginning of the next. The cell cycle can be divided into two types. They are as follows:
Interphase.M-phase (Division phase).Apart from this, the Cellular division has three main functions. It may include helping in the reproduction of an entire unicellular organism. Helps in the growth and repair of tissues in multicellular animals. Aids in the formation of gametes (eggs and sperm) for sexual reproduction in multicellular animals.
Therefore, the most fundamental function of the cell cycle is to duplicate accurately the vast amount of DNA in the chromosomes and then segregate the copies precisely into two genetically identical daughter cells.

What is biological hierarchy?Biological hierarchy refers to the organization of living organisms into a series of levels, each level being more complex than the one below it. The biological hierarchy begins with the smallest unit of life, which is the cell, and progresses upward to include tissues, organs, organ systems, organisms, populations, communities, ecosystems, and ultimately the biosphere.
Each level of the biological hierarchy is characterized by different properties and interactions. For example, cells are the basic unit of life and perform all the essential functions of an organism. Tissues are groups of cells that work together to perform a specific function, such as muscle tissue, which is responsible for movement. Organs are structures made up of tissues that work together to perform a specific function, such as the heart, which pumps blood throughout the body.
