VI
Answer:
Minerals from the land are washed into the ocean.
Salt in the ocean comes from the runoffs from the land, So the correct option is C. The minerals from the land are washed into the ocean.
Why are oceans salty?A large percentage of the earth is covered by water but 97 % of this water is salty and cannot be used. The salt in the ocean is added to by the erosion of rocks.
Rainwater contains dissolved carbon dioxide (CO2) from the surrounding air, which makes the rainwater slightly acidic due to the presence of carbonic acid. Rainwater physically damages the rock, and the acids chemically degrade the rock and transport salt and minerals in the form of ions. These ions are carried to streams and rivers, and eventually to the ocean.
The density of the ocean water is affected by the level of salinity. Higher levels of salinity cause water to be more dense and heavier and sink under less salty, warm water. This also affects ocean currents. In addition, marine life may need to adjust their saltwater intake.

how does each of your mutations affect the amino acid sequences? Are the mutations missense mutations, silent mutations or nonsense mutations?
a. Point mutation?
b. Frameshift-insertion?
c. Frameshift-deletion?
Answer:
the correct answer is B Frame shift insertion
Explanation:
plz give me brainiest
Frameshift-insertion mutations affect the amino acid sequences.
Thus, The insertion or deletion of nucleotide bases in amounts that are not multiples of three is referred to as a frameshift mutation in a gene.
This is significant because a cell reads the genetic code for proteins in groups of three nucleotides.
These so-called "triplet codons" each stand for one of the 20 different amino acids that go into making a protein. This normal reading frame will be disrupted by a mutation, which will result in an inaccurate reading of the entire gene sequence after the mutation.
Thus, Frameshift-insertion mutations affect the amino acid sequences.

What happens to a substance when it is heated?
a
Thermal energy is decreased
b
Potential energy is increased
c
Kinetic energy is increased
d
It does not change its physical shape
Answer: C
Explanation:
When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster: the space between atoms increases: The motion and spacing of the particles determines the state of matter of the substance: The end result of increased molecular motion is that the object expands and takes up more space.

How does oxygen enter the cells of the tube worm
Answer:
Flatworms are small, literally flat worms, which 'breathe' through diffusion across the outer membrane (Figure 2). The flat shape of these organisms increases the surface area for diffusion, ensuring that each cell within the body is close to the outer membrane surface and has access to oxygen.

An agricultural biologist was evaluating two newly developed varieties of wheat as potential crops. In an experiment, seedlings were germinated on moist paper towels at 20ºC for 48 hours. Oxygen consumption of the two-day-old seedlings was measured at different temperatures. The data are shown in the graph below. In a second experiment, variety A seedlings at both temperatures were treated with a chemical that prevents NADH from being oxidized to NAD+. Predict the most likely effect of the chemical on metabolism and oxygen consumption of the treated seedlings. Explain your prediction.
Answer:
The definition is listed in the clarification segment below, and according to the present circumstances.
Explanation:
It undergoes different morphological as well as biochemical modifications mostly during germination. Product contains nutrients and even some hydrolases such as energy, carbohydrates. Owing to the availability of phytic compounds, the seed coat seems to be very durable in nature. Hydrolytic enzymes launch their function by consuming oxygen throughout order to remove this hard coating. In several other processes, including the electron transport system as well as the Kreb process, oxygen also becomes necessary.
The initial phase of germinating seeds requires anaerobic environments where even the enzymes dehydrogenase can function. The subsequent dehydrogenase enzyme brings the electron throughout the electron transport system from either the base to oxygen. Unless the oxygen frequency is compared with varieties A and B, it can be seen through the analysis that variety B actually absorbed more oxygen. Oxygen intake rates are also depending upon period.The impact of temperature mostly on absorption of oxygen seems to be present. Shift the supply at low temperatures have a low intake of oxygen, while varieties grown over extreme temperatures use much more oxygen. The metabolism of such a seedling is influenced by temperature. Metabolically active young plants display a larger intake of oxygen.What is the function of the macromolecule nucleotide?

Answer:
D. None of the above
Explanation:
Energy transformation is the process of transfer and conversion of energy from one species to another. None of the above is not an example of energy transformation. Thus, option D is correct.
What is energy transformation?Energy transformation is the process in an ecosystem that includes the conversion of energy from one level to another in the food chain or the metabolic reactions.
Photosynthetic reactions under the sun, herbivores feeding on producers, and predators feeding on the primary consumers are examples of energy conversion as it is continuously passing the energy to another species in the ecosystem.
Therefore, none of the above is not an example of energy transformation.

Answer:
DNA to DNA: A, T, C, G
DNA to RNA: A, U, C, G
Explanation:
Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. In this process, adenine (A) pairs with thymine (T), while cytosine (C) pairs with guanine (G).
Transcription involves copying a gene's DNA sequence to make an RNA molecule. Transcription is performed by enzymes called RNA polymerases, which link nucleotides to form an RNA strand. In this strand, adenine (A) pairs with uracil (U) instead of thymine, but thymine (T) still pairs with adenine (A). Cytosine (C) and guanine (G) still pair to each other.

New Zealand has a population of 4,326,380 and has an area of 103,736 miles squared while Australia has an area of 2,967,909 miles squared and a population of 21,905,140. Explain how New Zealand can have a larger population density than Australia even though it has a smaller total population.
The reason they have a higher population density is because they have more people on average in a certain area, because New Zealand is smaller they are given less space to live, this means that more people are crammed together, making the density of people within a square mile higher. When you give less square miles, you reduce the amount you have to divide the population by, which makes the density go up.
( In case you wanted the calculations for the density on New Zealand and Australia, it is about 41 to 42 people a square mile in Zealand, and maybe 7 or 8 per square mile in Australia.)
