Answer:
ribose
Explanation:
Ribose, found in RNA, is a "normal" sugar, with one oxygen atom attached to each carbon atom. Deoxyribose, found in DNA, is a modified sugar, lacking one oxygen atom (hence the name "deoxy").

The dressing contains salt, which will draw out moisture from the lettuce and make it soggy.
Describe how the composition and structure of the atmosphere insulates the planet and protects organism.
Answer: because of its layers
Explanation:
The atmosphere protects life on Earth from incoming ultraviolet (UV) radiation, keeps the planet warm through insulation, and prevents extremes between day and night temperatures.
What is Atmosphere?
An atmosphere is defined as the layer of gas or layers of gases that envelop a planet, and are held in place by the gravity of the planetary body where the planetary atmosphere is present when gravity is great and the temperature of the atmosphere is low.
The Earth's atmosphere extends up to 10,000 kilometers above the surface of the planet, which merges into space.
Beyond the chemical composition which is necessary for life, the composition of the atmosphere in different thermal regions produces weather patterns that in turn determine climate while the upper atmosphere and its ozone layer protect living organisms on Earth from highly harmful UV-B radiation.
Thus, the atmosphere protects life on Earth from incoming ultraviolet (UV) radiation, keeps the planet warm through insulation, and prevents extremes between day and night temperatures.

If you find a reptile fossil buried and lithified among mud and decayed plant material, what type of depositional environment might you infer while the animal was still alive?
Answer:
The correct answer is - swamps/bog
Explanation:
Swamps or bogs are characteristically similar as they both area are known for the poor soil or muddy soil due to the quiet water conditions which is acuumulate by the precipitation mainly. These are have high peat content where mud and decaying or decomposing plant material found.
Bog or swamps are form due to the hundered years of decomposition or decys in plants and plants materials. As it stated that the reptile fossil buriiend lithified among mud and decayed plant material the environment must be bog or swamp.

What are the limitations of uranium-238 dating? How did you overcome
its limitations?
Answer:
4
Explanation:
Answer:
Uranium 238 is only found in igneous or volcanic rocks. So no fossils can be dated directly using U 238. Because of the huge differences in the half lives of Carbon 14 and Uranium238 they cannot be used together. Carbon 14 can only be used to date fossils of a very recent age.

what does a cell do to prepare for cell division
Answer:
interphase
A cell spends most of its time in what is called interphase, and during this time it grows, replicates its chromosomes, and prepares for cell division. The cell then leaves interphase, undergoes mitosis, and completes its division.
why is astronomy referred to as observational science and not primarily experimental science
Astronomy is referred to as observational science and not primarily experimental science because it focuses on the acquisition of data from observations of astronomical objects.
When this data are acquired,they undergo analysis and using basic principles of physics.
Unlike experimental Science which seems to build knowledge through directly observing and measuring of objects and phenomenon by scientists.
A good understanding of experimentation is important here.

How are cancer cells Different from normal cells?help!!! Due today!!!!
Answer:
In contrast to normal cells, cancer cells often exhibit much more variability in cell size—some are larger than normal and some are smaller than normal. In addition, cancer cells often have an abnormal shape, both of the cell, and of the nucleus (the “brain” of the cell.) The nucleus appears both larger and darker than normal cells.

Answer:
Please mark as brainliest!!!!!
Explanation:
The attractive force between water molecules is a dipole interaction. The hydrogen atoms are bound to the highly electronegative oxygen atom (which also possesses two lone pair sets of electrons, making for a very polar bond. The partially positive hydrogen atom of one molecule is then attracted to the oxygen atom of a nearby water molecule

How can we justify the conservation of energy using "system/surroundings" terminology for an open, closed, and isolated system?
Answer:
Closed systems do not exchange energy with the environment, while open systems do.
Explanation:
The cause of this is because closed systems are made up of an insulator that surrounds them and isolates them from the environment or adjacent environment.
This insulation prevents heat from being taken in or transferred from the surroundings as in the case of open systems.
scientific reason bio biosphere reserve is a boon for plant and animals
The correct answer to this open question is the following.
The scientific reason biosphere reserve is a boon for plants and animals because this reserve is under the supervision of specialists, scientists, and environmentalists. This protected area includes a diversity of animals, plants, and nature that requires conservation on the part of humans to maintain the proper conditions of the reserve. These living things and organisms interrelate with all the environment and scientists try to restore and supervise the growing and developing of the species in the reserve for the good of all mankind.

Why would your force of gravity increase if you went to a larger planet?
Answer:
because the gravity depends on the mass of object, if object is large or big it have more gravity than smaller one. As the large planet has large mass than small planets. So, force of gravity increases if we went to larger planet.

In an aquatic habitat it's important to monitor the levels of organisms such as dragon fly nymphs and leaches
due to the fact that they can be used to determine the effects of long and short term pollutants. HELPPPP it’s either true or false
Answer:
True
Explanation:
The given statement “In an aquatic habitat it's important to monitor the levels of organisms such as dragon fly nymphs and leachesdue to the fact that they can be used to determine the effects of long and short term pollutants” is true because they are considered bioindicators.
These organisms respond to the presence of pollutants, and their abundance and diversity can provide valuable information about the water quality. When certain pollutants are present in the water, the populations of these organisms may decline or show abnormal behavior, indicating the presence of short or long-term pollution effects.
Monitoring their levels and observing any changes over time can help identify pollution trends and assess the overall ecological health of the aquatic ecosystem. Dragonfly nymphs and leeches play a crucial role in the food chain of aquatic habitats. These organisms accumulate pollutants in their tissues, which magnifies the concentration of the contaminants as they move up the food chain.

The amino acid substitution of Val for Glu in Hemoglobin S results in aggregation of the protein because of _____ interactions between molecules. covalent disulfide hydrogen bonding hydrophobic ionic
Answer:
hydrophobic interactions
Explanation:
Hemoglobin S (Hb S) is an abnormal type of hemoglobin where red blood cells become sickle-shaped and these elongated cells have difficulty to pass through small blood vessels. This type of hemoglobin is caused by a substitution (Glu>Val, GAG>GTG) in a β-globin gene variant. When the normal sequence is altered, a different amino acid is synthesized and it modifies the interactions between side chains by hydrophobic interactions, thereby affecting protein folding.

Through which process could a large molecule such as protein EXIT the cholera cell?
—
A)diffusion
B)osmosis
C)exocytosis
D)endocytosis
Protein can exit a cholera cell through ; ( C ) exocytosis
Exocytosis is the process whereby secretory vesicles fuses with the plasma membrane and this leads to the discharge of the contents of the vesicle outside of the cell and into the extracellular fluid,
During Exocytosis large molecules like protein can exit a cholera cell because during exocytosis the contents of the cholera cell will be discharged outside the cell into the extracellular fluid.
Hence we can conclude that Protein can exit a cholera cell through ; ( C ) exocytosis.
