Does DNA in prokaryotes and eukaryotes use the same nitrogenous base pairs?
Answers
Answer:
Ukaryotes consist of membrane bound nucleus whereas prokaryotes lack a membranebound nucleus.
Explanation:
Ukaryotes consist of membrane bound nucleus whereas prokaryotes lack a membranebound nucleus. Prokaryotic DNA is doublestranded and circular. ... The main difference between prokaryotic and eukaryotic DNA is that prokaryotic DNA is found in the cytoplasm whereas eukaryotic DNA is packed into the nucleus of the cell.
No, DNA in prokaryotes and eukaryotes does not use the same nitrogenous base pairs.
What is DNA?Deoxyribonucleic acid is a polymer composed of two polynucleotide chains that coil around each other to form a double helix. The polymer carries genetic instructions for the development, functioning, growth and reproduction of all known organisms and many viruses. DNA and ribonucleic acid are nucleic acids.
Moreover, deoxyribonucleic acid (DNA) is a molecule that contains the biological instructions that make each species unique. DNA, along with the instructions it contains, is passed from adult organisms to their offspring during reproduction.
Therefore, in all living things, DNA is essential for inheritance, coding for proteins, and providing instructions for life and its processes. DNA dictates how a human or animal develops and reproduces, and eventually dies.

Hello! I have to write an essay based on the Water Cycle and what it is/does. I will give Brainliest for the correct answer. I will also give 20 points to whoever writes the essay, and has the correct answer. Good luck.
Answers
Answer: The water cycle also known as the hydrolic cycle describes the always foward rotation above and below the surfaces of the earth. The mass of water on earths surface remains fairly consistant. However, the water splits up into diffrent groups, freshwater, saline water, ice, and atmospheric water. The water can travel between catorgories such as river to ocean or ocean to atmosphere through evaporation, condensation, precipatation, surface runoff and subsurface flow. When water go through these physical process it can change aswell such as being a liquid, solid,and gas. During evaporation it takes water from it surroundings and cools its enviromwnt,
the exchanges in heat fluctuate the climates tempature.

How do your cells know what to do? Just like builders have blueprints to tell them how to build a house, your cells also have instructions. Your cells' instructions are molecules of DNA.
What is DNA?
DNA is the material that makes up our chromosomes and stores our genetic information. When you build a house, you need a blueprint, a set of instructions that tells you how to build. The DNA is like the blueprint for living organisms. The genetic information is a set of instructions that tell your cells what to do.
DNA is an abbreviation for deoxyribonucleic acid. As you may recall, nucleic acids are a type of macromolecule that store information. The deoxyribo part of the name refers to the name of the sugar that is contained in DNA, deoxyribose. DNA may provide the instructions to make up all living things, but it is actually a very simple molecule. DNA is made of a very long chain of nucleotides. In fact, in you, the smallest DNA molecule has well over 20 million nucleotides.

Prokaryotic chromosomes have telomeres, and eukaryotic chromosomes do not.
Prokaryotic chromosomes have a single origin of replication, while eukaryotic chromosomes have many.

The rate of elongation during replication is slower in prokaryotes than in eukaryotes.

A population of rabbits in an ecosystem has genetic variation in fur thickness. Some rabbits have thick fur and others have thin fur. Due to changes in the environment, the average temperature of the ecosystem is steadily increasing.
How will this environmental change likely affect the rabbit population over time?
A. Rabbits with thick fur will become more common in the population because thick fur will be a favorable trait in this changing environment.
B. Rabbits with thin fur will become more common in the population because these rabbits are more likely to survive and successfully reproduce.
C. Rabbits with thick fur and thin fur will become equally distributed because all rabbits in the population will successfully reproduce.
D. Rabbits with both fur types will increase in the population because the temperature change will cause the population of rabbits to expand.
Answers
Answer:
B
Explanation:
Thin fur is better for warmer weather, so the rabbits with thinner fur won't over heat in the warming weather.
The population of rabbits n the genetic ecosystem has thick fur and others have thin fur, due to the changes in the climate avg temperature of the ecosystem is steadily falling.
Looking at the situation and adaptive powers or abilities of the animals the thick fur will survive longer than those of the thin fur as the temperature of the place is declining.Hence the option A is correct.

Which experiment could the scientists use that would best determine if these tiny structures are spores?
Answers
Answer:
The experiment that scientists could use that would best determine if the tiny structures are spores is called Opto-Electronic Imaging and Imaging Processing.
Explanation:
Optoelectronics speaks to the body of knowledge and of electronic devices that source, detect and control light and how they are used or applied. It is founded on the quantum mechanical effects of light on electronic materials.
Besides Optoelectronic Imaging, there are several other techniques that can be used to identify spores. Some of them are:
1. The culture-based methods: These methods involve the growing of spores on an agar plate and on the enumeration of colony units formed therein.
2. Culture-independent methods: These methods are based on
the counting of spores under an electron microscope. This method utilizes the hybridization of DNA for the detection of pores. Opto-electric imaging is preferred and considered more efficient because it is faster than all the above processes that have been mentioned. The above processes have the disadvantage of time-consumption.

Why are chromosomes so important that they must be precisely and correctly duplicated, sorted, and distributed when one cell divides into two daughter cells?
Answers
Answer: It is important that the daughter cells have a copy of every chromosome, so the process involves copying the chromosomes first and then carefully separating the copies to give each new cell a full set.

2 Asexual reproduction differs from sexual reproduction in that, in asexual reproduction..
(a) new organisms are usually genetically identical to the parent
(b) the reproductive cycle involves the production of games
(c) nuclei of sex cells fuse to form a zygote
(d) offspring show much genetic variation
Answers
Answer: 1. Mitosis
2. Answer A.
Explanation:
Stick insects that reproduce asexually are less biologically diverse because they can't evolve as quickly as species that reproduce sexually can. Thus, option A is correct.
What is role of asexual reproduction in evolution?Asexual reproduction, in contrast to sexual reproduction, only contributes to genetic variety in the population if a chance mutation in the organism's DNA is passed on to the progeny.
Evolution can occur gradually. Asexual creatures often evolve relatively quickly following a dramatic mutation and do not need as many generations to accumulate adaptations as do populations that reproduce sexually.
Asexual reproduction has the benefit of allowing for rapid population growth under the right circumstances. You only require one parent. Since you don't require a partner, it is more time and energy efficient.
Therefore, new organisms are usually genetically identical to the parent.
