Before DNA was discovered, in which materials did scientists think the genetic material was stored?

Answers

Answer 1
Answer:

Answer: We all know that DNA act as repository of genetic information in most organism. But before the discovery of DNA it was thought that proteins act as a genetic material because protein is the final product of the cell dogma of cellular system and proteins helps in the formation of tissues and organs.

At what age is the difference between the average height of boys and girls greatest?Estimate this difference to the nearest centimeter.

Answers

Answer:

Sixteen years old is the age where the biggest difference between the average height of boys and girls can be observed. This is a difference of approximately 5.7 cm.

Explanation:

As we know, for biological reasons, boys and girls have different growths and different development in their bodies. However, the growth and development of boys and girls during childhood is very similar and only starts to look different even from adolescence, where individuals have great structural differences.

At 16 years of age, boys and girls have the greatest mean difference in height. While in previous years this difference was on average 1 centimeter, at 16 years old, girls are 150.8 cm tall on average, while boys are 156.5 cm tall.

Due to the average rate of growing starting to properly sprout at the age 11, surely those years around it would be the greatest difference.
I think there is about a 15cm difference on average.

What type of cell is the cell membrane​

Answers

Answer:

All cells have an outer plasma membrane that regulates not only what enters the cell, but also how much of any given substance comes in. Unlike prokaryotes, eukaryotic cells also possess internal membranes that encase their organelles and control the exchange of essential cell components.

Explanation:

The cell membrane, therefore, has two functions: first, to be a barrier keeping the constituents of the cell in and unwanted substances out and, second, to be a gate allowing transport into the cell of essential nutrients and movement from the cell of waste products.

The image shows a paramecium and a bacterium. One of these organisms is very good at rapidly adapting to environmental changes because it has the ability to take in stray genetic information from the environment. Which structure allows the organism to do this?

Answers

Genetic variation enables bacteria to adapt to changes in their environment. Since, bacteria reproduce asexually (binary fission), they can share genes (genetic transfer) via other mechanisms such as conjugation (exchange of genetic material through direct contact between two bacteria), transformation, and transduction(exchange of genetic material via bacteriophages).

Transformation is a process by which bacteria takes in DNA from its environment through the cell membrane.
