The genetic code is said to be universal. Which of the following lines of evidence would best support this idea?
Data that indicate that the genetic code changes frequently.
Data that are inconclusive about the nature of.
the genetic code.
Data that indicate that some organisms use one or more alternate codes.
Data that indicate that the genetic code is the same in all organisms tested so far.
Answer:
hi here is your answer....
Explanation:
Data that indicate that the genetic code is the same in all organisms tested so far.
becuase,
The genetic code is nearly universal, and the arrangement of the codons in the standard codon table is highly non-random. The three main concepts on the origin and evolution of the code are the stereochemical theory, according to which codon assignments are dictated by physico-chemical affinity between amino acids and the cognate codons (anticodons); the coevolution theory, which posits that the code structure coevolved with amino acid biosynthesis pathways; and the error minimization theory under which selection to minimize the adverse effect of point mutations and translation errors was the principal factor of the code’s evolution.

Two plates moving towards each other are called convergent plates. Which
structures are likely to form at a convergent plate boundary?
A:rift valley
B:wave erosion
C:mountains
D:river canyons
Mountains are formed when two convergent plates move towards each other. Therefore, option C is correct.
What are convergent pates?A convergent plate boundary is a type of tectonic plate boundary where two tectonic plates are moving toward each other. As the plates move, they can collide, resulting in the formation of various geological features and processes, such as mountain ranges, volcanic eruptions, and earthquakes.
Convergent plate boundaries are one of the three main types of plate boundaries, along with divergent and transform plate boundaries. They are important in shaping the Earth's surface and are associated with some of the most spectacular geological features on the planet.
Thus, mountains are formed when two convergent plates move toward each other. Therefore, option C is correct.

4. Why
are stomata important to a plant?
Answer:
stamina are important portals for gas and water exchange in plants and have a strong influence on characteristics associated with photosynthesis and transpiration
Answer:
Stomata are composed of a pair of specialized epidermal cells referred to as guard cells (Figure 3). Stomata regulate gas exchange between the plant and environment and control of water loss by changing the size of the stomatal pore.

9. a) How does hydrogen bonding help the transport of water in plants?
Answer:
Water has a high Cohesion because of Hydrogen bonding. This is important as transport of water in the Xylem in plants relies on water being pulled up. Cohesion also gives the water a high surface tension, allowing small organisms, such as Pond Skaters, to walk along it.
Explanation:
Water molecules forming hydrogen bonds with one another. The partial negative charge on the O of one molecule can form a hydrogen bond with the partial positive charge on the hydrogens of other molecules. Water molecules are also attracted to other polar molecules and to ions.
Plants obtain the hydrogen they need from water molecules. Don't try to feed your plant hydrogen gas -- your plant wouldn't know what to do with it if you did. As long as they have water, plants can readily obtain all the hydrogen they need. :)
Two plants are grown in different yards. One yard has plenty of water and almost no sunlight. Both plants have inherited genes that allow them to grow. Do you think these plants will grown to the same height? Explain your answer.
Answer:
No they won't be the same height because the plant with sunlight will be longer than the one with almost no sunlight this is because plants are drawn to light, so if there is almost no sunlight then the plant dons't really grow.
Explanation:
They won't be the same height because plants are drawn to light, therefore if there is little to no light, the plant doesn't really grow. Instead, the plant with sunshine will be longer than the one with nearly little sunlight.
What is photosynthesis?The process by which plants convert carbon dioxide, water, and sunshine into oxygen and sugar-based energy is known as photosynthesis.
Plants wilt when they are not adequately watered. Turgor, or the pressure of water inside the cells that make up the plant's skeleton, is to blame for this. Through the stem of a plant, water enters and ascends to the leaves.
Plants are attracted to light, so if there is little to no light, the plant won't actually develop, and they won't be the same height.
Instead, the plant that receives more sunlight will be longer than the one that receives almost no sunlight.
Thus, this can be the scenario for the given experimentation.

what is the meaning of ph
Answer:
pH is a measure of how acidic/basic water is. The range goes from 0 to 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base. pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water.

What is the significance of the planetary model?The planetary model is very significant, as the heliocentric model, proposed by Nicolaus Copernicus, explains that the sun is at the center of the solar system and shows that the planets, including Earth, revolve around the sun. This heliocentric model provided a more accurate explanation of the movements of the planets and paved the way for future research.
