how are petrified remians formed
Answers
Explanation:
Petrified fossils form when minerals replace the structure of an organism. This process, called permineralization, occurs when groundwater solutions saturate the remains of buried plants or animals. As the water evaporates the minerals remain, eventually filling in the spaces left as the organism slowly decays.

Answers
Answer:
The correct answer is ''post-zygotic barrier to reproduction''
Explanation:
Biological barriers prevent the exchange of genes between two or more populations, a postzygotic reproductive barrier reduces the survival or reproduction of hybrid offspring. In hybrid non-viability there is low survival of the hybrid, especially during embryonic stages. On the other hand, the sterility of the hybrid occurs when the fertilized egg develops into a healthy but sterile adult. Segregation of aneuploid gametes during meiosis, different gene associations occur on the chromosomes of the parents.

•wind •ocean currents •both wind and ocean currents •neither wind nor ocean
Answers
Explanation : The uneven heating of the regions of the troposphere by the sun ( the sun warms the air at the equator more than the air at the poles ) causes convection currents, large-scale patterns of winds that move heat and moisture around the globe. As air rises, expands, and cools, water vapor condenses and clouds develop.

Sensory neuron(s) then transmit information from the sensory receptor(s) to the Central Nervous System
Explanation:
These receptors are located all over the body but some types of receptors are in specific areas of the body (e.g. taste receptors in the mouth).
Sensory neuron(s) then transmit information from the sensory receptor(s) to the Central Nervous System (i.e. the brain and spinal cord, sometimes referred to in the abbreviated form: C.N.S.). This is happens because peripheral nerves all connect to the spinal cord via the network of nerves within the nervous system.
The information so received by the C.N.S. is further transmitted by relay neurone(s) with the C.N.S.

2. Energy flows through Earth's spheres and changes along the way. Describe how energy is conserved in these systems. (2 points)
Answers
Answer:
Teaching about energy and physical processes is supported by 7 key concepts:
2.1 Earth is constantly changing as energy flows through the system. Geologic, fossil, and ice records provide evidence of significant changes throughout Earth's history. These changes are always associated with changes in the flow of energy through the Earth system. Both living and non- living processes have contributed to this change.
2.2 Sunlight, gravitational potential, decay of radioactive isotopes, and rotation of the Earth are the major sources of energy driving physical processes on Earth. Sunlight is a source external to Earth, while radioactive isotopes and gravitational potential, with the exception of tidal energy, are internal. Radioactive isotopes and gravity work together to produce geothermal energy beneath Earth's surface. Earth's rotation influences global flow of air and water.
2.3 Earth's weather and climate are mostly driven by energy from the Sun. For example, unequal warming of Earth's surface and atmosphere by the Sun drives convection within the atmosphere, producing winds, and influencing ocean currents.
2.4 Water plays a major role in the storage and transfer of energy in the Earth system. The major role water plays is a result of water's prevalence, high heat capacity, and the fact that phase changes of water occur regularly on Earth. The Sun provides the energy that drives the water cycle on Earth.
2.5 Movement of matter between reservoirs is driven by Earth's internal and external sources of energy. These movements are often accompanied by a change in the physical and chemical properties of the matter. Carbon, for example, occurs in carbonate rocks such as limestone, in the atmosphere as carbon dioxide gas, in water as dissolved carbon dioxide, and in all organisms as complex molecules that control the chemistry of life. Energy drives the flow of carbon between these different reservoirs.
2.6 Greenhouse gases affect energy flow through the Earth system. Greenhouse gases in the atmosphere, such as carbon dioxide and water vapor, are transparent to much of the incoming sunlight but not to the infrared light from the warmed surface of Earth. These gases play a major role in determining average global surface temperatures. When Earth emits the same amount of energy as it absorbs, its average temperature remains stable.
2.7 The effects of changes in Earth's energy system are often not immediately apparent. Responses to changes in Earth's energy system, input versus output, are often only noticeable over the course of months, years, or even decades.
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.
Answers
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.
Hybrid cars can switch back and forth between gasoline power and electric power in a way that reduces fuel use
As a result, they are more fuel efficient than traditional cars that run only on gasoline. They offer one solution to
the problem of people consuming too many fossil fuels to meet their transportation needs.
Which of the following behaviors could further refine this solution?
A. People can drive hybrid cars instead of using more conservative tecnics.
B. People can drive separate hybrid cars instead of carpooling
C. People can use additional conservation tactics, like sometimes bicycling
D. People can drive hybrid cars more often than they need to
Answers
Answer:
C. People can use additional conservation tactics, like sometimes bicycling
Explanation:
According to this question, cars called HYBRID cars are said to have the ability to switch back and forth between gasoline power and electric power in a way that reduces fuel use. This solves the problem of buying excessive transport fuel.
Asides the hybrid car, one can also use a more conservative approach, which is bicycling. Hence, the use of additional conservation tactics, like sometimes bicycling.

Bloodworms, which are the mature larvae of non-biting midge flies, are commonly found in and around bodies of water. Most types of bloodworms can live only in pollution-free, oxygen-rich environments. However, a few species thrive in environments with low concentrations of oxygen and high concentrations of nutrients and pollutants. From the changes in the bloodworm populations shown in the table above, what can be determined about how water in the stream has changed?
A. The water has become less polluted, as evidenced by the decrease in the number of bloodworm species present and the increase in bloodworm population density.
B. The water has become more polluted, as evidenced by the decrease in the number of bloodworm species present and the increase in bloodworm population density.

In humans blood type is determined by the A, B, and O alleles. The A and B alleles are codiminant to each other and dominant over the O allele. An individual with the AO genotype and an individual with the BO genotype can produce offspring with which of the following phenotypes.
O only
A or B only
A, B or O only
A, B, AB, or O
Please explain, also this is not a test its a test PREP
Answers
Answer:
D. A, B, AB, or O
Explanation:
We can start by visualizing all the possible genotypes of the offspring by drawing a Punnett square, which is a visual representation of the different possible combinations of alleles:
Individual 1 = AO, Individual 2 = BO
A O
B AB BO
O AO OO
Here we can see that there are 4 possible genotypes: AB, BO, AO and OO based on the alleles of the parents. Now we can match the genotypes to phenotypes to answer the question:
A and B are codominant, meaning that both will be expressed equally if both are present. Therefore the genotype AB will result in an AB phenotype.
Next, since A and B are both dominant over O, they are the alleles that will be expressed in the phenotype if paired with an O. This means that the genotype AO will result in an A phenotype, and likewise, genotype BO will result in phenotype B.
Finally in the genotype OO, although O is a recessive allele, there are no dominant alleles here to mask them, therefore O is expressed in the phenotype.
Hence, from the genotypes AO and BO, the possible offspring genotypes are AB, BO, AO and OO, translating to the possible phenotypes: A, B, AB or O.

In horses, black coloring (B) is dominant, and chestnut coloring (b) is recessive. What percentage of offspring are expected to be chestnut?
Answers
Answer:
This question is incomplete, the complete question is as follows:
- In horses, black coloring (B) is dominant, and chestnut coloring (b) is recessive. A homzygous black horse crosses with a chestnut horse.
What percentage of offspring are expected to be chestnut?
The answer is 0%
Explanation:
This question involves a gene coding for color in horses. The allele for black coloring (B) is dominant over the allele for chestnut coloring (b) is recessive.
According to this question, if a homzygous black horse (BB) crosses with a chestnut horse (bb), the following gamete will be produced by each parent;
BB - B only
bb - b only
Using these gametes in a punnet square, the following proportion of offsprings will be produced:
Bb, Bb, Bb, Bb
All of these offsprings are phenotypically black colored although heterozygous in genotype. Hence, 0% of offspring are expected to be chestnut.
