Question:When is water the most dense?
Question:When is water the least dense?
Explanation:
Water density changes with temperature and salinity. Density is measured as mass (g) per unit of volume (cm³). Water is densest at 3.98°C and is least dense at 0°C (freezing point).
The two bar graphs show the average temperature and precipitation in a temperate climate, like you might find in most of the U.S.
Imagine you are on a trip to Brazil for the summer Olympics. How might the temperature graph differ in that climate?

Describe the bonding between ionic compounds
Answer:
Ionic bonding is the complete transfer of valence electron(s) between atoms. It is a type of chemical bond that generates two oppositely charged ions. In ionic bonds, the metal loses electrons to become a positively charged cation, whereas the nonmetal accepts those electrons to become a negatively charged anion.Explanation:

Why are only four amino acids produced by 5 codons? I need this answer ASAP
Answer:
My answer (that the information we have about codon structure is limited to the observations we can make now) is similar to the first part of your answer: that the number of amino acids that can be encoded is a function of codon length, in that both imply the (circular) argument that we must need more than 14 amino acids (plus a start and a stop, making 16) because we observe three nucleotide codons rather than two nucleotide codons. It would be nice to have a noncircular argumentf for why the minimum number of distinct amino acids is more than 14, but that is beyond my ability to construct
A, T, C, and G are the only letters found in DNA, however, a protein may include up to 20 distinct amino acids. Codons assist in translating the DNA code into a protein code at this point.
What are genetic codons?For the body to develop and work effectively, 20 different amino acids are required. All 20 of them are crucial for your health, but only 9 are considered to be absolutely necessary.
This is due to the degeneracy of genetic codes, one of their characteristics, the remaining 3 codons are called "stop" codons since they do not code for any amino acids. The sequences UAA, UAG, and UGA include the stop codon information.
Therefore, only 61 of the 64 possible codon combinations code for amino acids.

What happens when the Earthis plates pull away from each other? What happens when they push together?
Answer:
Two plates pushed together create a convergent fault. If one plate is oceanic and the other continental, the edge of the oceanic plate will be pushed down. When two plates move away from each other they create a divergent boundary. When this happens under oceans, new ocean floor is created.

Fill in the space where it says hypothesis stated look in the photo I don’t have that much time
The purpose of the experiment is above
Answer:
The hypothesis of the experiment states that the density of a liquid can affect the properties and the way this liquid interacts with others.
Explanation:
In an experiment, the hypothesis is an assumption, that is, it is something that the researcher believes to be true. To confirm this assumption, the experiment must present facts that show that this assumption is correct and true.
In this case, the purpose of an experiment is to confirm a hypothesis. In this case, if the purpose of the experiment is to find out if the density of a liquid can affect the properties and how that liquid interacts with other liquids, it is because the hypothesis of this experiment assumes that the density of the liquid has the ability to modify the properties and the interaction of this liquid with others.
17. How does the placement of the stamen in relationship to the pistil affect the way in which
the flower is fertilized?
Answer:
this placement increases the chances of pollination
Explanation:
Pollination refers to the process of transferring pollen grains from the male stamens of a flower to the female stigma. The stamens generally surround the pistil and they are composed of two structures: 1-the anther (produces male reproductive cells or pollen grains) and 2-filaments (supports the anthers). Moreover, the female pistil is generally located at the center of the flower and it is composed of three structures: stigma (a sticky bulb in the center of flower), ovary (contains female reproductive cells or ovules), style (supports the stigma). The arrangement of the plant's reproductive organs increases the chances of pollination: when a pollinator (e.g. bees) visits a stigma for nectar it has to go through the stamen and catch pollen that then carries to the stigma of the same flower (auto-pollination) or another flower (cross-pollination). Moreover, the flowers also have petals and sepals that help attract pollinators and protect the flower bud, respectively.

Which of the following is a nonrenewable resource?
O wind power
O geothermal energy
O oil
O solar energy
Answer:
Oil
Explanation:
Since, unlike oil, source like wind, solar, water etc. come naturally we don't and can't replace them but when the viscosity in oil has been used up it must be change to allow the proper functioning of the machine.
The next resource that is a nonrenewable resource is the oil that is present in the third option, as the oil is a fossil fuel that is formed over millions of years and is not renewable on human timescales.
What is a nonrenewable resource?Nonrenewable resources are natural resources that are finite and cannot be replenished or regenerated on a human timescale, and they are formed over millions of years, and their supply is limited, as oil is a nonrenewable resource that is formed from the remains of plants and animals that lived millions of years ago. These were buried under layers of sediment and rock, and over time, heat and pressure caused them to decompose and transform into oil, and the problem with nonrenewable resources like oil is that they are finite, meaning that there is only a limited supply of them.
Hence, the next resource that is a nonrenewable resource is the oil that is present in the third option.

Which of the following are all abiotic factors?
A. Primary consumers, secondary consumers, and producers
B. Sunlight, precipitation, wind speed, and temperature range
C. Detritivores, herbivores, carnivores, and omnivores
D. Microorganisms and mineral content
Explanation:
Option B is correct as abiotic factors includes non-living factors.
Answer:
B is the correct answer.........
a. The logistic equation reflects the effect of density-dependent factors, which can ultimately stabilize populations around the carrying capacity. b. Density-independent factors have an increasingly greater effect as a population's density increases. c. High densities in a population may cause physiological changes that inhibit reproduction. d. Because of the overlapping nature of population-regulating factors, it is often difficult to precisely determine their cause-and-effect relationships. e. The occurrence of population cycles in some populations may be the result of crowding or lag times in the response to density-dependent factors.
Question:
Which of the following is an incorrect statement about the regulation of populations?
Answer:
b. Density-independent factors have an increasingly greater effect as a population's density increases.
Explanation:
A population can be defined as the total number of living organisms living together in a particular place and sharing certain characteristics in common.
Generally, these populations may be divided into a fraction of the population (subpopulation) based on certain factors and reasons.
Population change equation states that the change in the size of a population over a specific period of time is equal to the sum of the number of births and the number of immigrants that joined.
Mathematically, the population change equation is given by the formula;
Population Change = (Natality - Mortality) + (Immigration - Emigration)
Population regulation can be defined as a biological process that balances limiting factors affecting the growth of a population based on density. The factors that regulate the growth of a population are divided into two (2) main categories and these includes;
I. Density-independent factors.
II. Density-dependent factors.
Density-dependent are regulating factors such as predation, diseases, and competition that affect the size of the population of living organisms through decreasing or increasing mortality and birth rate.
Furthermore, density-independent factors do not have an increasingly greater effect as a population's density increases. Thus, its effect are reduced as a population's density increases in size.
