do DNA and RNA have the same phosphate group?
Answer: yes they do
Explanation: In a cell, a nucleotide about to be added to the end of a polynucleotide chain will bear a series of three phosphate groups. When the nucleotide joins the growing DNA or RNA chain, it loses two phosphate groups. So, in a chain of DNA or RNA, each nucleotide has just one phosphate group.

your school? Write down each type of land use.
Then describe how one of these land uses might
affect natural systems.
Answer:
The grass in the field How this effects is because its a comfertable place for alot of things to live
Explanation:
Drag each tile to the correct location.
Identify each process as a carbon source or a carbon sink.
Carbon sources are any natural or artificial production site of carbon and/or any chemical compounds composed of carbon, such as carbon dioxide and methane.
Carbon source: Combustion,Respiration.
A carbon sink absorbs carbon dioxide from the atmosphere.
Carbon sink: Photosyntheis,Ocean absorption,Fossilization.
Which one is carbon sink or carbon source?1. Photosyntheis: Forests are typically carbon sinks, places that absorb more carbon than they release. They continually take carbon out of the atmosphere through the process of photosynthesis.
2. Ocean absorption: Phytoplankton are the main reason the ocean is one of the biggest carbon sinks. These microscopic marine algae and bacteria play a impotant role in carbon cycle - absorbing carbon.
3. Fossilization: Absorb CO2.
4. Combustion: Combustion is a chemical process in which a substance reacts rapidly with oxygen and gives off heat and CO2 in environment.
5. Respiration: The respiratory system, with its conduction and respiratory zones, brings air from the environment to the lungs and facilitates gas exchange both in the lungs and within the cells and gives out CO2 in atmosphere.
Thus, we can conclude that
carbon sink: Photosyntheis,Ocean absorption,Fossilization.
carbon source:Combustion,Respiration.

Membrane bound-organelles have been an important component in the evolution of complex, multicellular organisms. Which of the following best summarizes the advantage of eukaryotic cells having internal membranes? a. Eukaryotic cells are able to reproduce faster because of the presence of organelles b. Some organelles, such as mitochondria and chloroplasts, are similar to prokaryotic cells in structure. c. Organelles isolate specific reactions, increasing metabolic efficiency. Compartmentalization leads to a higher mutation rate in DNA, which leads to more new species.

Mutations are changes to an organisms DNA that creates diversity within a population by introducing new alleles. Some mutations are harmful and are quickly eliminated from the population by natural selection harmful mutations prevent organisms from reaching sexual maturity and reproducing.
Why are people with type o blood considered universal donars?
Answer:
because they can donate blood to anyone
Explanation:
People with type O- blood are called universal donors because their donated red blood cells have no A, B or Rh antigens and can therefore be safely given to people of any blood group. ... Their plasma does not contain A or B antibodies and can be transfused safely to all blood types.

why must both constricting and posionous snakes eat their prey alive?
Answer:
There is a very common misperception among people, even among many snake hobbyists, that snakes must have live prey.
Explanation:
This is not usually true. In the wild, snakes, like most other carnivores, will usually take any opportunity to get a free and easy meal, and will not pass up a freshly killed prey animal if they happen upon it. In fact, snakes have been known to eat a fair amount of carrion which has been dead for some time, and the stomach contents of wild snakes often contain prey that must have been in an advanced state of decomposition when it was eaten. Thus, although your snake may prefer to eat live prey, which it kills itself through constriction, this is not at all necessary for the health of the snake. In fact, it is best not to feed your captive snakes live prey at all.

how does skin help with homeostasis? include the terms stimulus and response
Answer:
The skin provides a protective layer for the inner organs, helps to regulate temperature, water balance, receives sensory stimuli, produces vitamins, etc.
Explanation:
The integumentary system can be defined as an organ system composed of different organs, i.e., skin, hair, exocrine glands, nails. The skin helps in homeostasis by providing a protective layer for the inner organs, contains immune cells involved in immune responses, regulates temperature, water balance, receives sensory stimuli, production of vitamins. The skin contains sensory receptors for different stimuli including touch, pain, pressure, and temperature (both heat and cold receptors). The inflammatory response (inflammation) occurs when harmful microorganisms penetrate the skin, thereby causing skin inflammation. The skin's immune cells include, among others, neutrophils (located in the reticular dermis), macrophages (papillary and reticular dermis), T lymphocytes (epidermis and papillary dermis), Langerhans cells (epidermis), etc.

Are identical twins mutations? And why
Answer: Research published on January 7 in the journal Nature Genetics shows that identical twins differ by an average of 5.2 genetic mutations. ... In such studies, scientists often assume that pairs of identical twins have identical DNA, so their differences can be explained by the environments they grew up in. That's because so-called identical twins pick up genetic mutations in the womb, as their cells weave new strands of DNA and then split into more and more cells.
Explanation:
A new mutation arises in one person on the island of Kiribati (human population size 100,000). Assuming this particular mutation is total neutral, and assuming no gene flow, what is the probability that this mutation will eventually be lost due to genetic drift
Answer:
0.999999 ≈ 1
Explanation:
In a population ( N ) there is the presence of 2N alleles in the population also chance of fixation can be expressed as ; 1/ 2N
Therefore the probability that the mutation will be lost due to genetic drift
= 2N - 1 / 2N ---- ( 1 )
given that ; N = 100,000
back to equation 1
P ( losing mutation due to genetic drift ) = ((2*100,000) - 1 )) / ( 2* 100,000 )
= ( 200,000 - 1 ) / 200,000
= 0.999999 ≈ 1

In a certain animal, a breed is known that always has a hairy tail; another breed is known that always has a naked tail. How would you determine which trait is dominant?
the dominant trade should be the hairy tail if its seen more often, naked tails are resesive and are seen less often, hope that helped
In a certain animal, it is possible to determine a dominant trait by crossing purebred lines and observing the proportion in offspring.
What are purebred lines?The purebred lines are genetic lineages of organisms that are homo-zygous for a given genetic/phenotypic trait.
It is possible to determine the dominance level of phenotypic features by crossing purebred lines.The proportion of the phenotypic traits in progeny will evidence the presence of dominace.In conclusion, in a certain animal, it is possible to determine a dominant trait by crossing purebred lines.
