Answer:

A scientific experiment refers to a detailed and organized array of steps that are needed to reject or validate the framed hypothesis. The steps, which are incorporated in a scientific experiment are:  

1. Identification of independent variable: The independent variable is the one that can be manipulated or changed in an experiment, that is, the effect of which can be witnessed on a dependent variable.  

2. Address any confounding variable: It is the one that comes from the outside, the changes resulting due to this variable impart an effect over the independent and dependent variables. This variable can bring change in the outcome of the experiment.  

3. Form a non-falsifiable hypothesis: A non-falsifiable hypothesis refers to the one that can be proved true on the basis of the implementation of suitable methodology and research design.

loris [4]

Answer:

Golgi receives a vesicle containing newly synthesized proteins that were sent by the endoplasmatic reticulum. Then it modifies the proteins and sends them where they need to go.

Explanation:

Protein synthesis is initiated in the cytoplasm when mRNA meets a free ribosome, which is the primary structure for protein synthesis. They read the mRNA code and add the correct amino acid using transference RNA to build the protein. The synthesizing protein is driven to the rough endoplasmic reticulum and translocated to the lumen. Once there, the protein suffers a few modifications, one of them is folding to become functional. Once membrane proteins are folded in the interior of the endoplasmic reticulum, they are <u>packaged into vesicles</u> and <u>sent to the Golgi complex</u>, where it occurs the <em>final association of carbohydrates with proteins</em>. The Golgi complex <u>sends proteins to their different destinies</u>. Proteins destined to a certain place are packaged all together in the same vesicle and sent to the target organ. In the case of membrane proteins, they are packaged in vesicles and sent to the cell membrane where they get incrusted.

Describe temperate grassland ecosystem characteristics. Include climate, an example of a producer, and an example of a consumer
Aliun [14]

Answer:

A grassland is a biome where dominant vegetation is grasses, a consumer of this biome can be a herbivore (e.g., a rabbit). Coral reefs are home to millions of species of marine animals.

Coral reefs, seaweed and forest biome

Coral reefs are fundamental for protecting wildlife in marine ecosystems.

Seaweed is a common plant in the Euphotic Zone (Sunlight Zone, also called Epipelagic Zone), along with algae and phytoplankton.

Temperate broadleaf forests are represented by areas with marked warm and cool seasons that show moderate annual average temperatures (3 °C  to 25 °C).

Examples of producers in a temperate broadleaf forest may be Eucalyptus species, whereas consumers may include, for example, elk

A grassland is experiencing a severe drought. The lack of rain is causing the grass to die and the ponds and creeks to dry up.
dusya [7]

The population of fish will decrease.

The population of grazing animals will decrease.

<h3>What is drought?</h3>

A drought is a prolonged period without enough precipitation/water to support people, animals or crops.

With less water, fish and other creatures have fewer places to dwell, swim, and evade predators. In the near run, shrinking streams and lakes necessarily result in fewer fish. Drought conditions can cause water temperatures to rise, affecting cold-water species such as native trout.

The population of grazing animals would decrease as the grass is a food source and without their food source, there would be no source of staying meaning that they would result to finding new food sources through migration likely.
