How did Watson and Crick learn about Chargoff's rules?

Answers

Answer:

Chargaff explained his findings and research to Watson and Crick at Cambridge.

Explanation:

Watson and Crick met Erwin Chargaff at Cambridge in 1952, where he explained his research and findings to them. His rule of parity, or 1:1 rule, stemmed from his discovery of guanine's equal ratio in pairing with cytosine.

Watson and Crick went in to use Chargaff's findings and the work of the researcher Rosalind Franklin as a basis for their work on DNA's double-helical structure.

What is an organism?

An organism, especially a cow, is a living thing. An organism is a singular living being that exhibits characteristics of life, such as the ability to develop, reproduce, respond to stimuli, and preserve homeostasis. Mammalia, a class of multicellular organisms including cows, forms the animal kingdom. Cows are complex biological entities with specialized sensory and digestive systems that enable them to live and thrive in their environment.

The following three terms are used to describe cow-like creatures:

Cows are mammals, which are warm-blooded animals with hair or fur and the ability to feed their young with milk.

Herbivores: Cows are herbivores, which means they only eat plants and no animal products like meat or dairy.

Cows are included in the class of herbivorous mammals known as ruminants, which have a four-chambered stomach.

A.transcription → replication → translation
B.replication → cell division I → cell division II
C.mitosis → cell division I → translation
D.cell division I → cell division II → transcription

Answers

Answer:

part c

Explanation:

The sequence replication → cell division I → cell division II describes the formation of gametes.

Where does the formation of gametes occur?

Meiosis (reduced division), in which a germ cell splits into two pieces and produces four gametes, is the process by which gametes are created.

Meiosis is a type of cell division that results in the production of four gamete cells and a 50% reduction in the number of chromosomes in the parent cell.

The gonads are where gametes (germ cells) are made. This process is known as spermatogenesis in males and oogenesis in females. The majority of novel mutations arise during gametogenesis, however males exhibit a higher mutation rate.

3H2O is the correct answer

Answer:

D. 3H2O

Explanation:

An atom is the smallest unit of matter that has the characteristics of a chemical element. It consists of protons, neutrons, and electrons - small electrically charged particles.

They make up molecules - electrically neutral groups of two or more atoms connected by chemical bonds. Multiple molecules that consist of two or more different atoms make up a chemical compound.

The chemical compound that has nine atoms is 3H2O. Here, we have three molecules of water. Each molecule consists of three atoms - two hydrogen atoms and one oxygen atom. This means that three of these molecules have a total of nine atoms.

5. Knowing that acid rain has a pH of 2-3, would you conclude that crop species with a narrow soil pH range are in trouble? Is acid rain a problem for plant species and crops?

Answers

Answer:

Yes

Explanation:

Unless the crops acidity range is that of the rain( which it wouldn't be) it would throw off the crops Ph balance and harm it.

Yes, crop species with a narrow soil pH range are potentially in trouble due to acid rain. Acid rain can have harmful effects on plant growth and productivity. The acidity of the rain can change the pH level of the soil, making it more acidic and less hospitable for plants.

What is acid rain?

Acid rain is a type of rain or other precipitation that is unusually acidic and has elevated levels of hydrogen ions (low pH). It is caused by the release of sulfur dioxide (SO2) and nitrogen oxides (NOx) into the atmosphere, which then reacts with water vapor to form sulfuric acid and nitric acid.

These acids can fall back to the ground as acid rain or other forms of precipitation and can cause harm to plants, animals, and infrastructure. Acid rain can also contribute to soil and water pollution and can have negative impacts on human health.

Acidic soil can also release toxic substances, such as aluminum, which can further damage plant roots and reduce plant growth. In addition, acid rain can damage plant foliage directly, leading to reduced photosynthesis and reduced yields.

So, acid rain can be a significant problem for plant species and crops, particularly those with a narrow soil pH range.

Im grateful for the calm water today because it enables me to ascend to the top level of the SS Frisia and look at the Atlantic Ocean that stretches before us until it meets the horizon. I feel the warm air on my face and smell the salty sea air, but theres a pit in my stomach when I think about how different life in New York will be.When we first set sail on August 21st, I watched until Hamburg became a miniscule speck in the distance. When I squinted and couldnt see the familiar buildings with their smoke spewing into the air anymore, Papa told me to look the other way. You cant look back, he said as he walked me to the other side of the ship, his strong arm supporting my shoulders. Home is there now. He pointed to a place that was shimmering waves of blue, and I had a hard time visualizing a home that was 6,000 kilometers of water. He told me to close my eyes and picture the skyline that would soon materialize on the horizon. I couldnt even fathom 6,000 kilometers of water, just like I couldnt fathom that our new home wouldnt be Hamburg anymore.Most of the days at sea have been turbulent; tall waves reach up from the bottom of the sea and smack into the ship, sending us to the ground whenever we are standing. We are jettisoned from one side of the ship to the other like billiard balls; we emigrants glance off one another before moving in separate directions. It was entertaining at first, but now the ships rocking motion makes me feel sick, so I descend back to the bottom level where my familys room is. Through the tiny oval porthole, I watch as the rough water laps the glass.We play games and read and sleep to pass the timesometimes theres violin music that drifts into our room at night. My brother and I step out into the hallway in our socks and dance to the fast beat together, and it makes the boats rocking seem bearable. Most nights, we practice some English words with one another peppered in with the German that I will soon use less and less. I am from Germany, I practice over and over again, elongating my mouth around vowels that are pronounced differently in English than in German. I still think in German, dream in German, feel German words fly off my tongue with a comfort and speed that I worry Ill never feel when I speak English. What will happen to me if the English all around me displaces the German of my youth?There are people on this ship from everywhere: The Kowalski family in the room next to ours is from Poland, while the Ivanov family on the other side is from Russia. We practice basic English with one another: Good morning. How are you? Behind the closed doors of strangers rooms, I hear unfamiliar consonant sounds making up the lyrics to lilting songs. I can only imagine that these melodies are about feeling adrift; though we come from different places, nostalgia and homesickness know no borders or boundaries.When I write these letters to you, I wonder where you are and what you are doing. Are you still walking along the canals of the Speicherstadt the way we used to after school? Do you still hear the bells of St. Michaels Church resounding through the air? Does the bakery on the corner still serve our favorite Brtchen when it comes right out of the oven?I miss you more than I can say in this letter. Say hello to everyone for me and tell them that my family is doing well.
