Answer: DNA and RNA are both examples of nucleic acids
They consist of a strand of nucleotides with a phosphate group, a 5′ sugar and a nitrogenous base.
Extra info: DNA and RNA molecules are polymers. DNA is double stranded, whereas RNA is single stranded.
The nucleotides of DNA can pair together by base pairing, creating a strand that is complementary to its pair
Various types of RNA exist which have roles in protein synthesis as well as regulation of cellular programmes by fine-tuning gene expression.

Explanation:
which molecules are not able to permeate the cell membrane
Answer:
Small uncharged polar molecules, such as H2O, also can diffuse through membranes, but larger uncharged polar molecules, such as glucose, cannot. Charged molecules, such as ions, are unable to diffuse through a phospholipid bilayer regardless of size; even H+ ions cannot cross a lipid bilayer by free diffusion.

Explanation:
if a blue eyed offspring is formed from black eyes parents, what type of character is the blue eye dominant or recessive? expalin with the help of a chart
Answer:
Blue Eyes Are: Recessive
Explanation:
The brown eye form of the eye colour gene (or allele) is dominant, whereas the blue eye allele is recessive. If both parents have brown eyes yet carry the allele for blue eyes, a quarter of the children will have blue eyes, and three quarters will have brown eyes. I hope this helps :) Good luck on your assignment!!!

Explanation:
Occasionally a new resistant strain of pathogen appears. The new strain may spread rapidly. Explain why
Answer:
Antibiotics are not effective for new strains and so new resistant pathogens survive and reproduce, which leads to the increasing population of resistant pathogens and spread rapidly.
Bacteria can evolve and adapt themselves quickly as they are able to reproduce at a fast rate. Mutations of bacteria produce new strains that are resistant to certain antibiotics, such as penicillin, and cannot be destroyed by the antibiotic so they spread more rapidly.

PLEASE HELP BEING TIMED Which is one piece of information that fossils in samples from Earth's crust reveal about Earth's history?
A. Changes in climate
B. Number if species at the specific time
C. Composition of Earth's core
D. Age of organisms when they died
Answer: changes in climate
Change in climate information that fossils in samples from Earth's crust reveal about Earth's history. So, the correct option is (A).
What are Fossils?A fossil is defined as the preserved remains, impression, or trace of a once-living thing from a past geological age, including bones, shells, exoskeletons, fossilized traces of animals or microbes, amber, hair, petrified wood, and DNA. The totality of fossils is known as the fossil record.
There are five types of fossils which are as follows:
Body FossilsMolecular FossilsTrace FossilsCarbon FossilsPseudo fossilsThe fossil record shows that the types of living things on Earth changed over time which reveals the Earth's history.
Thus, change in climate information that fossils in samples from Earth's crust reveal about Earth's history. So, the correct option is (A).

Please help me it’s due today , there’s number 10 also
Answer:
1. Chloroplast
2. Photosynthesis
3. 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
4. Sunlight
5. Glucose
6. Oxygen
7. Carbon Dioxide
8. Water
9. Energy

Answer:
1. Chloroplast
2.photosynthesis
3. 6 CO₂ (carbon dioxide) +12 H₂O (water) + light -->C6H12O6 (glucose/sugar) +6 O₂ (carbon dioxide) + 6 H₂O (water)
4. Light
5 and 6) Glucose (C₆H₁₂O₆) and O₂
7 and 8) CO₂ and Water (H₂O)
9) energy (ATP)
10) Mitochondria
11) Cellular respiration
12) I think you need the equation as well:
Explanation: C₆H₁₂O₆ (glucose) + 6O₂ (oxygen) --> 6CO₂ (Carbon Dioxide) + 6 H₂O (water) + ATP (energy)
1. Chloroplasts have thylokoids or stacked membranes like it has.
2. Photosynthesis is the process of converting light into usable energy.
3. That is the equation of photosynthesis. Their are different ways of writing this for example: 6 CO₂ + 6H₂O + light -->C₆H₁₂O₆ + 6 O₂ which is balancing the water. Check to see what your teacher used in the book/notes.
4. Light is required for photosynthesis and the sun is providing it.
5 and 6) The mitochondria uses both of these in its processes that were first made in photosynthesis.
7 and 8) Both are created by mitochondria and are used in chloroplasts.
9) Energy is produced in the mitochondria with help from the Chloroplast.
10) It is usually depicted with those lines in it.
11) That is the process's name.
12) This is the equation of cellular respiration.

_______________ is the name for the process of clearing natural vegetation and replacing it with concrete and buildings.
The practice of removing natural vegetation and replacing it with concrete and structures is known as urbanization. This is the correct answer to fill in the blank.
What are the primary factors causing urbanization?Industrialization, commercialization, rural-urban migration, lifestyle changes, career opportunities, social advantages, etc. are the primary reasons of urbanization. The process of urbanization is when people move from rural to urban areas for a variety of reasons.
What results did urbanization produce?Urban areas can expand due to a rise in the population or because people move there. Urbanization frequently causes habitat loss, deforestation, and freshwater extraction from the environment, which can reduce biodiversity and change species ranges and interactions.

The heartbeat rate of an athlete during resting is lower than a non-athlete.
Explain why. [ 2 marks ]
Answer: The heart muscle of conditioned athletes enlarges and strengthens.
Increased cardiovascular fitness causes real physical changes in the structure of the heart. The muscles in the heart wall thicken, and the heart pumps more blood with each beat. That increased efficiency means an athlete's resting heart rate falls to a level that could indicate trouble in a nonathlete. Many athletes don't realize that high levels of conditioning also cause heart symptoms that doctors might mistake for serious problems.

How may mRNA be modified before it leaves the nucleus?
Answer:
The pre-mRNA molecules undergo three main modifications. These modifications are 5' capping 3' polyadenylation and RNA splicing which occur in the nucleus before RNA is translated.
Explanation:
mRNA compares to the hereditary succession of quality, and is perused by a ribosome during the time spent combining a protein.
How mRNA can be modified?it should go through extra handling before it leaves the core. This might incorporate joining, altering, and polyadenylation. These cycles adjust the mRNA in different ways. Such alterations permit a solitary quality to be utilized to make more than one protein. Exons are segments of mRNA which become "communicated" or converted into a protein. They are the coding bits of a mRNA atom.
