Answer:
Karl von Frisch is best known for two major discoveries about honey bees. First, he demonstrated that honey bees have color vision, and published these findings in 191*. Second, in 193* he showed that honey bees use a dance language to communicate food locations to other bees.
Explanation:
Figure 1. Grids for the color vision test. The training color, marked with T, is blue in both cases; all other squares are shades of gray. The left box shows how the grid appears to an animal with color vision. The right box shows how the same grid may appear to an animal without color vision. The training square appears to be the same shade of gray as other squares in the grid. If the test animal cannot see in color, it will confuse the training square with other squares matching its shade of gray.
This clever test for color vision can be applied to any animal which can learn to recognize a feeding station using visual patterns.
The dance language
von Frisch observed that once one honey bee finds a feeding station, many other soon appear at the same station. This suggests that the first bee recruits other bees to the food. How might honey bees recruit help in collecting food? von Frisch¹s discovery of the dance language of the honey bee required careful determination of the correlations between movements of bees inside the hive and the locations of feeding stations. He found two types of dance. The round dance (Figure 2A) causes bees to look for food a short distance (up to about 50 meters) from the hive. The waggle dance (Figure 2B) tells bees the direction and distance to fly to find more distant food sources. Scout bees use these dances to recruit assistance in collecting food resources.

Why do you think the size of a white dwarft affects its visual luminosity?
Answer:
White Dwarfs are extremely difficult to detect as they are quite small compared to a Star. If the area is small the Luminosity is low, which would make it harder to see the white dwarfs due to the low amount of its luminosity.

Why is using the presence of chromosomes inside of a cell NOT a reliable method to
determine if the cell is a prokaryote or a eukaryote?
Because both prokaryotic and eukaryotic cells have chromosomes (prokaryotes, and more specifically, bacteria, generally have just one chromosome, but there are some bacteria as well as archaea—which are also prokaryotes—that have multiple chromosomes).
Since the chromosomes are DNA molecules present in both the prokaryotic and eukaryotic cells, it is not a reliable method to determine if a cell is prokaryotic or eukaryotic
The nucleus of a eukaryotic cell is bounded by internal membrane, therefore, it is distinctive.
In contrast, the nucleus of a prokaryotic cell lacks internal membrane, hence its nucleus is not distinctive.
Chromosomes are Deoxyribonucleic (DNA) molecules that carry genetic information of a cell or organism.
The chromosomes are present in both the eukaryotic and prokaryotic cells. Chromosomes present in the eukaryotic cells are called eukaryotic chromosomes while chromosomes present in the prokaryotic cells are called prokaryotic chromosomes.
Since the chromosomes are DNA molecules present in both the prokaryotic and eukaryotic cells, it is not a reliable method to determine if a cell is prokaryotic or eukaryotic

Answer:
flowers

skin
According to cell theory flowers, blood, bacteria and skin all are made up of cells.
What is cell theory?The cell theory is a scientific theory that was initially developed in the middle of the nineteenth century, which states that all living organisms are composed of cells, that cells are the fundamental structural/organizational unit of all organisms, and that all cells originate from pre-existing cells.
Knowing that all living things are cells helps us comprehend how they are born, grow, and die. That information helps us understand how new life is produced, why creatures take their forms, how cancer spreads, how diseases can be handled, and more. Cells help us grasp life and death: a living creature is alive, while a dead one is dead.
Therefore, flowers, blood, bacteria and skin all are living things made up of cells.

why are index fossils useful to geologist
a.they tell the relative age of the rock in which they occur
b. they tell the ages of many different rock layers
c.they tell the age of the rock at one location only
d. they tell the absolute age of the rock in which they occur
Answer:
Explanation:
Index fossils (also known as guide fossils or indicator fossils) are fossils used to define and identify geologic periods (or faunal stages). Index fossils must have a short vertical range, wide geographic distribution and rapid evolutionary trends.
Index fossil, any animal or plant preserved in the rock record of the Earth that is characteristic of a particular span of geologic time or environment. A useful index fossil must be distinctive or easily recognizable, abundant, and have a wide geographic distribution and a short range through time. Index fossils are the basis for defining boundaries in the geologic time scale and for the correlation of strata. In marine strata, index fossils that are commonly used include the single-celled Protista with hard body parts and larger forms such as ammonoids. In terrestrial sediments of the Cenozoic Era, which began about 65.5 million years ago, mammals are widely used to date deposits. All of these animal forms have hard body parts, such as shells, bones, and teeth, and evolved rapidly.
