1.Theodor Schwann

2.Anton van Leeuwenhoek

3.Rudolph Virchow

4.Albert Einstein

(Will give brainliest to correct answer)

Answers

Answer 1

Answer: The correct answers are:

1. Theodor Schwann

2. Anton van Leeuwenhoek

3. Rudolph Virchow

Explanation: The cell theory is a fundamental concept in biology and states that all living organisms are made up of one or more cells, that the cell is the basic unit of life, and that all cells arise from pre-existing cells. This theory was developed over time by multiple scientists, but the three main contributors to the cell theory are Theodor Schwann, Anton van Leeuwenhoek, and Rudolph Virchow.

Theodor Schwann was a German physiologist who, in 1839, stated that animals are made up of cells. He further went on to propose that all living organisms are composed of cells.

Anton van Leeuwenhoek was a Dutch scientist who, in 1674, discovered bacteria and protozoa, among other microscopic organisms, by using a microscope that he designed himself.

Rudolph Virchow was a German physician who, in 1855, stated that all cells arise from pre-existing cells. This concept is known as the principle of biogenesis and it is a key part of the cell theory.

Why do you think the Arecibo message and the beacon in the Galaxy were broadcast in binary code?

Answers

Answer:

Hi!

The Arecibo message and the beacon in the galaxy were broadcast in binary code because binary is a universal language that can be easily understood by any intelligent beings, regardless of their language or culture. Binary code consists of only two symbols, 0 and 1, which can be used to represent any information, including letters, numbers, and instructions. This makes binary an ideal choice for transmitting messages over vast distances, as it is less prone to errors and can be decoded with a high degree of accuracy.

Why do your fingers look like prunes after swimming for a long time?

Answers

Answer:

pruney fingers are caused by shrinking blood vessels. When you soak in water, your nervous system sends a message to your blood vessels to shrink. Your body responds by sending blood away from the area, and the loss of blood volume makes your vessels thinner.

Answer:

This is because when you swim in a pool for a while your hand seem to be pruney and it is because when the hand is soaked in water, the nervous system sends a message to the blood vessels in your hand to shrink.

And the reduction of blood from the area in your which is soaked and then your hand seems like pruney

Fix nitrogen is from soil, plants and animals consuming it which causes it to recycle, nitrogen is cycled through: plants, soil, animals, bacteria and water and the atmosphere. I hope this helped!

Explanation:

Bacteria breaking down nitrogen compounds releases free nitrogen.Explanation:The nitrogen cycle is a process in which nitrogen is recycled through different components of the environment. Bacteria play an important role in this cycle by breaking down nitrogen compounds found in plants, animals, and soil. When bacteria break down these compounds, they release free nitrogen into the environment. This free nitrogen can then be used by other organisms like plants to create proteins and other essential molecules. So, bacteria breaking down nitrogen compounds is an important step in the nitrogen cycle.

MIGHT GIVE BRAINLIEST Compare a paramecium with a giraffe. How are their cells alike? How are they different? Write
your answer in complete sentences. be original

Answers

Answer:

A paramecium is similar to a giraffe in one defining way. Both a giraffe and paramecium have eukaryotic cells. One way in which the two are different is that the paramecium feeds on decaying organisms, whilst a giraffe eats leaves. Another is that paramecium primarily live in fresh water, while a giraffe dwells on land.

A paramecium and a giraffe are two very different organisms. A paramecium is a single-celled organism, while a giraffe is a large, multicellular mammal. Despite their many differences, both a paramecium and a giraffe have cells. However, the cells of a paramecium and a giraffe are quite different from each other in terms of size, shape, and function.

One of the most significant differences between the cells of a paramecium and a giraffe is their size. The cells of a paramecium are very small, measuring only a few micrometers in diameter. In contrast, the cells of a giraffe are much larger and more varied in size, depending on their function within the body. For example, giraffe nerve cells are much larger than giraffe red blood cells.

Another important difference between the cells of a paramecium and a giraffe is their shape. The cells of a paramecium are typically elongated and oval-shaped, with a pointed end at one end and a rounded end at the other. In contrast, the cells of a giraffe are much more varied in shape, depending on their location and function within the body. For example, giraffe muscle cells are long and cylindrical, while giraffe nerve cells are elongated and have many branching extensions.

Despite their many differences, the cells of a paramecium and a giraffe do have some similarities. For example, both types of cells have a cell membrane that surrounds the cell and controls the movement of materials in and out of the cell. Both types of cells also have a cytoskeleton, which provides support and structure to the cell. Additionally, both types of cells have a nucleus, which contains the cell's genetic material.

Overall, while the cells of a paramecium and a giraffe have some similarities, they are also very different from each other in terms of size, shape, and function. The small, simple cells of a paramecium are adapted for life in a single-celled organism, while the larger, more complex cells of a giraffe are adapted for life in a multicellular mammal.

cheif keef

Explanation:

5),[5] better known by his stage name Chief Keef, is an American rapper. Cozart's music first became popular during his teen years in the early 2010s among high school students from Chicago's South Side.[6] In 2012, his popular local single "I Don't Like" was remixed by American rapper Kanye West and reached the Billboard Rap Top 20, further raising Cozart's profile.[6] A bidding war between major labels resulted in Keef signing with Interscope. His debut album Finally Rich was released in December 2012, and featured the singles "I Don't Like" and "Love Sosa", which would popularize the Chicago rap subgenre drill.[7]

Chief Keef has faced ongoing legal issues during his career, including weapons possession charges, house arrest sentences, and a performance ban imposed by Chicago authorities.[8] Though he was dropped from Interscope in late 2014 and later signed to 1017 Records, he continued self-releasing projects through his own Glo Gang label. These included: Nobody (2014), Back from the Dead 2 (2014), Bang 3 (2015), and Th0t Breaker (2017).

By the late 2010s, critics have pointed to Chief Keef as a major influence on contemporary hip hop through his innovation with the drill subgenre and the impact of his music on other artists.[9][7][10]

A pedigree chart is used to _______.

predict genotypic probabilities
track inherited traits through generations

Answers

A pedigree chart is used to track inherited traits through generations.

A pedigree chart is a visual tool that represents the inheritance patterns of specific traits or genetic conditions within a family. It helps to trace the occurrence of traits, diseases, or genetic conditions across multiple generations by depicting the relationships between individuals and their affected or unaffected status.

Pedigree charts are commonly used in genetics and genetic counseling to analyze patterns of inheritance, identify carriers of genetic disorders, determine the probability of passing on certain traits or diseases, and study the transmission of traits within families. By examining the patterns of inheritance in a pedigree chart, one can gain insights into the mode of inheritance, such as autosomal dominant, autosomal recessive, or X-linked inheritance, and make predictions about the likelihood of certain traits or conditions appearing in future generations.

The genotype of the plant is GR. This is because the offspring received green allele (G) as well as red allele (R), and both results showed up as the plant is green with red veins.

When something gives up alleles to its offspring, the parents originally have alleles like Aa and Bb. When offspring is created, you can use the Punnett square to guess which alleles will be passed on. In the plant’s case, G and R were passed on.
