A science class tested ways to clean water after an oil spill. Each group of students was given 100 mL of vegetable oil, 100 mL of engine oil, and 800 mL of water in a rectangular plastic container. Each container also held five floating wooden cubes (5 cubic centimeters each) representing animals in the water. Each group was tasked with removing as much oil as possible in a 20 minute period, leaving “clean water” in the container, using whatever tools they brought to class. The results of the “clean-up” are presented in the table below.

Group
Vegetable oil removed (mL)
Engine oil removed (mL)

10
20
2
110
130

Based on the results above, which group’s data are obviously unreliable?
group 1
group 2
group 3
group 4

Structure C, D, and E in the diagram represent the endoplasmic reticulum, the ribosome, and the Golgi apparatus respectively.

When the ribosomes are attached to the endoplasmic reticulum, they give it a rough appearance.

The ribosome, endoplasmic reticulum, and the Golgi apparatus work together in the synthesis and transport of protein within the cell. In other words, they are all involved in the secretory pathway of cells.

In other words, the 3 organelles work together to form the secretory pathway of the cell. They are involved in the synthesis, packaging, processing, and eventual transport of proteins to their target sites.

Answer:

Irrigation is the artificial process of applying controlled amounts of water to land to assist in the production of crops, but also to grow landscape plants and lawns, where it may be known as watering. 

Answer:

Irrigation is the artificial application of water to the soil through various systems of tubes, pumps, and sprays. Irrigation is usually used in areas where rainfall is irregular or dry times or drought is expected. There are many types of irrigation systems, in which water is supplied to the entire field uniformly.

A research question is the basis of the experimental analysis of the subject matter. A hypothesis is said to be the potential solution to a research question. Thus, option D is correct.

The hypothesis has been defined as the supposition that acts as the basis of the research and experiment and has been constituted of some evidence and facts to formulate the research question.

It acts as a starting point for any investigation and research and must be falsifiable. They should be testable in order to determine the verifiability of the research topic. If the tested hypothesis is correct then further research is conducted.

It can also be defined as an educated guess that is based on some prior knowledge and facts that are deduced through experiments.

Therefore, the hypothesis is a potential solution.

No

Explanation:

According to science, human beings can't observe cells and other tiny organisms with our naked eyes coz our eyes aren't strong enough to observe but we can use a microscope which has strong lenses.

As cell is a tiny microscopic structure, it can be visible under microscope only.

Cell is the basic unit of any living organism, can be observed in animal, plant, microbes etc; Bacteria are unicellular in nature, all higher eukaryotic organisms are multicellular in nature like plants and animal cell.

The simplest type of cells are prokaryotic cells have a cell membrane, cytoplasm where all of the metabolic processes occur, ribosomes where protein synthesis occur, and nucleoid which carry genetic information, reproduce by binary fission.

The eukaryotic cells have cell membranes, cytoplasm, ribosomes, and nucleus a house of DNA, rough endoplasmic reticulum for protein assembly, smooth endoplasmic reticulum for lipids, Golgi apparatus for protein sorting and exporting.

It has mitochondria energy house, a cytoskeleton for structure and passes information, and  lysosomes or peroxisomes for digestion of waste, vacuoles for water storage, chloroplasts for photosynthesis.

Answer:

a blood clot is a gelatinous mass of fibrin and blood cells formed by the coagulation of blood

Explanation:

Answer:

The process of forming a clot or thrombus in order to prevent excess loss of blood from the body is called the clotting of blood. A jelly mass like substance is formed by the platelets and fibrin in the blood. Platelets play a vital role in the clotting of blood.

Given below is the flow chart representing the major steps involved in the process of clotting of blood:

Injury to blood vessel and platelets release prothrombin

⇓

Activation of prothrombin to thrombin

⇓

Splitting up of fibrinogen to fibrins by thrombin

⇓

A mesh is formed around the wound controlling RBC and platelets by fibers present in fibrins

⇓

Bleeding is stopped

⇓

The clot hardens and becomes smaller in size

⇓

New cells are grown to rebuild the wounded site

⇓

Plasmin enzymes are released and the clot is dissolved

Answer:

A daughter can become a carrier in one of two ways – she can acquire the ‘gene’ from a carrier mother or from a color blind father.

Explanation:

If a woman has only one color blind ‘gene’ she is known as a ‘carrier’ but she won’t be color blind. When she has a child she will give one of her X chromosomes to the child. If she gives the X chromosome with the color blindness ‘gene’ to her son he will be color blind, but if he receives the X chromosome which doesn’t carry the color blindness ‘gene’, he won’t be color blind.

A color blind boy can’t receive a color blind ‘gene’ from his father, even if his father is color blind, because his father can only pass an X chromosome to his daughters.

A color blind daughter therefore must have a father who is color blind and a mother who is a carrier (who has also passed the color blindness ‘gene’ to her daughter). If her father is not color blind, a ‘carrier’ daughter won’t be color blind. A daughter can become a carrier in one of two ways – she can acquire the ‘gene’ from a carrier mother or from a color blind father.
