The group of choices is:
peas have a relatively short generation time
peas produce large numbers of seeds
he could control which parents were involved in mating
peas only reproduce by cross-fertilization
peas have many polymorphic traits
Answer:
The correct answer is - peas only reproduce by cross-fertilization
Explanation:
Pea plants not just produced by cross-pollination but self-pollination is also one of the reproduction methods present in it. Pea plants have many type of characteritics or traits that can be controlled by the researcher in parent plants during the mating process.
The generation is relatively short which helps in the study the pattern of inheritance of the traits up to several generations.
Thus, the correct answer is - peas only reproduce by cross-fertilization

girl all you gotta do is use Google..
"Actively dividing eukaryote cells pass through a series of stages known collectively as the cell cycle: two gap phases (G1 and G2); an S (for synthesis) phase, in which the genetic material is duplicated; and an M phase, in which mitosis partitions the genetic material and the cell divides."
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.

which molecule can form hydrogen bonds with others like
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

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.

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.
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.

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.
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.
