Answer:

1. Upwelling of warming ocean water.

In step 4, upwelling of warming ocean water takes place.

Upwelling is the natural process which brings cold, nutrient-rich water to the surface. A huge upwelling regularly occurs off the coast of Peru, which enjoys a large fishing industry as a result.

The upward movement of this deep, colder water is called upwelling. The deeper water that rises to the surface during upwelling is rich in nutrients. These nutrients “fertilize” surface waters, encouraging the growth of plant life, including phytoplankton.

Water that rises to the surface as a result of upwelling is typically colder and is rich in nutrients. These nutrients “fertilize” surface waters, meaning that these surface waters often have high biological productivity.

Essentially, a control variable is what is kept the same throughout the experiment, and it is not of primary concern in the experimental outcome. Any change in a control variable in an experiment would invalidate the correlation of dependent variables (DV) to the independent variable (IV), thus skewing the results.

Answer:

If the grass is removed, then the grasshopper will not get any food. If the grasshopper does not get food, then the species will decrease and eventually die out. When the grasshopper dies out, then the lizard and the frog will have no food and they will die out. When they die, the snake will have only mice to eat, and there would be more competition. In the end, the food web would be unbalanced.

Answer:

1. Scientific probe.

2. Weather station.

3. Weather station.

4. Scientific probe.

Explanation:

1. Scientific probe: measures a variety of data, including pH levels and conductivity. Thus, a scientific probe is a device that is typically used for measuring science-based data such as electrical conductivity, pH levels, salinity etc., of various materials.

2. Weather station: measures temperature, humidity, wind speed, and pressure. Basically, a weather station comprises of various devices for measuring atmospheric conditions such as thermometers, barometers, hygrometer, wind vane etc., used for the measurement of temperature, atmospheric pressure, relative humidity and wind speed respectively.

3. Weather station: gathers information about local atmospheric conditions.

4. Scientific probe: can digitally record data, such as flow rate.

Answer:

Trait.

Explanation:

Trait can be defined as a distinguishing quality or characteristic of a living thing.

Simply stated, a trait refers to the specific features or characteristics possessed by a living organism. It is essentially transferred from the parent of a living organism to her offspring and as such distinguishes him or her.

Some examples of traits in genetics are colorblindness, handedness, curly hair, height, complexion, weight, hair color, dimples, tongue-roll, etc.

For example, John is so tall and has a curly hair, it's obvious he acquired the trait from his mum.

Explanation:

The Gila monster is one of only a handful of venomous lizards in the world. Others include the similar-looking Mexican beaded lizards, as well as iguanas and monitor lizards. Its venom is a fairly mild neurotoxin. And though a Gila bite is extremely painful, none has resulted in a reported human death.

It has been accused of many things, such as spitting venom, leaping several feet in the air to attack, stinging with its tongue, and killing people with gusts of poisonous breath. ... It may even chew so that the venom goes deeper into the wound. A Gila monster bite is painful to humans, but it rarely causes death.

Powerful muscles control the jaws and give the Gila Monster a bite like a bulldog--it just won't let go. This gives the venom a chance to work, weakening or disabling the lizard's prey.

Muscle cell most closely regulates protein synthesis it follows that ribosomes, which are found in the cytoplasm and rough endoplasmic reticulum, are where protein synthesis or translation of m-RNA to protein occurs, hence option 1 is correct.

Sarcoplasmic reticulum is a specific type of ER found in skeletal muscle (SR). The SR is essential for both the contraction of muscles and the preservation of muscle homeostasis because it serves as a calcium storage depot and controls the release of calcium during myofibrillar contraction.

Ribosomes: Ribosomes are crucial cell organelles involved in the production of proteins.  Proteins and RNA found in ribosomes assist in translating genetic instructions into proteins.

Therefore, the endoplasmic reticulum part of the muscle cell most closely regulates protein synthesis.

Somatic cells are diploid(they have 2n chromosomes) while gametes are haploid(they have n chromosomes). During fertilization two gametes fuse to form a diploid cell(n+n=2n). If gametes were diploid(2n chromosomes) every generation the number of chromosomes would double (2n+2n=4n)

Somatic cells are diploid(they have 2n chromosomes) while gametes are haploid(they have n chromosomes).

During fertilization two gametes fuse to form a diploid cell(n+n=2n). If gametes were diploid(2n chromosomes) every generation the number of chromosomes would double (2n+2n=4n).

The body's somatic cells are those that are neither sperm or egg cells (which are called germ cells).

Somatic cells in humans are diploid, which means they have two sets of chromosomes, one from each parent. Somatic cell DNA mutations can have an impact on an individual, but they cannot be passed on to the individual's progeny.

Therefore, Somatic cells are diploid(they have 2n chromosomes) while gametes are haploid(they have n chromosomes).

Answer and Explanation: The role of oil/grease in the hanging drop experiment can not be over emphasised especially for small volume trials.

The macromolecule solution to be crystalized is mixed with a precipitating agent on a glass plate. This is then inverted over greased wells creating an overhang.

Greasing the wells ensures a proper seal as it acts as an inert sealant that prevents the evaporation of the solution, but also can easily contaminate the macromolecule solution to be crystalized. Grease also affects the crystallization process throughout its stages of nucleation and growth, and also enhances the stability of the emerging crystals.

Answer:

Explanation:

Answer:

Due to its spreading nature.

Explanation:

Transboundary environmental threats like pollution is a problem for both parties i. e. one that is producing pollution and the other which is not producing it, because pollution can't remain at one place and spread from one part to another part of the earth due to open environment. So due to its spreading, it affected both the producing and non-producing parties.

Answer:

Even when pollution originates on one side of a border, it often spreads through the environment beyond the point of origin, becoming a shared problem. It is important to track the sources of pollution to identify the policies and sources for prevention efforts, but regardless of the source of pollution, once a border area becomes polluted, the pollution is a health threat for all individuals on either side of the border.

Answer:

It would be the opposite of the high temperature graph.

Explanation:

i got it right and thats all that matters

The graph for average low temperatures would look like the opposite of the high-temperature graph.

A climate graph displays yearly temperature and precipitation statistics for a particular location. Temperature is measured using the numbers on the left-hand side of the chart. The average temperature for each month is plotted on the graph with a red dot and the dots are then connected in a smooth, red line.

Two common types of graphs are bar graphs and line graphs. Bar graphs use vertical or horizontal rectangles (bars) to represent a specified quantity. Line graphs use points to identify values, and then connect each point with a line that shows the fluctuations in the data.
