Which of the following about Dalton's theory of matter is true? A Atoms of the same element have the same mass. B Compounds formed from two elements will not always have the same proportions. C Atoms cannot be divided into smaller parts.
Describe the path of an oxygen atom through four reservoirs of the oxygen cycle. Explain the process involved in the transfer between these reservoirs. Also, note the reservoirs in the path where the oxygen atom bonds to a carbon atom.
Answer:
The four main reservoirs of oxygen cycle are terrestrial biosphere, marine biosphere, lithosphere and atmosphere.
Explanation:
Oxygen is present about 21 % in the atmosphere which comes to the earth surface i. e. terrestrial biosphere where animals and microbes use this oxygen for the process of respiration while plants are the only organisms which produces oxygen in the process of photosynthesis and this oxygen goes to the atmosphere. This atmospheric oxygen also dissolve in water which is used by the marine animals. Oxygen atom is also present with carbon atom in the form of food molecules such as glucose which is produced inn the process of photosynthesis.
The oxygen cycle is a biogeochemical cycle, in which oxygen is circulated through the lithosphere, atmosphere, rhizosphere, and biosphere. The amount of oxygen present in the Earth's atmosphere is 21%.
The oxygen's primary reservoirs are the biosphere, atmosphere, and lithosphere.
The atmosphere or the air constitutes 21% of the oxygen. The organisms present on the terrestrial surface consume oxygen via respiration.
In the biosphere, autotrophs like plants produce oxygen via photosynthesis. The oxygen is then delivered to the atmosphere, where it is again utilized by terrestrial organisms.
The oxygen when dissolved in the water is used by marine organisms in the form of dissolved oxygen.
In the lithosphere, the oxygen is circulated through chemical weathering, which the formation of iron oxides. Chemical weathering can lead to the release of oxygen in the atmosphere.
Therefore, the oxygen can be circulated through terrestrial organisms, marine animals, the lithosphere, and the atmosphere through different processes like weathering and photosynthesis.

Earlobes can be either attached or detached. The allele for attached earlobes
is recessive (e), and the allele for detached earlobes is dominant (E). What
must be true if a boy is born with attached earlobes?
A. He has a heterozygous genotype.
O B. He has no E alleles.
C. He has no recessive alleles.
O D. He has one of each allele,
SUBMIT
Answer:
B. He has no E alleles.
Explanation:
In order for the boy to have an attached earlobes phenotype, he must have no E alleles, because the E is dominant. So his genotype must be ee. If he has even just a single E allele (like Ee) he will have detached earlobes, because the dominant trait will mask the expression of the recessive trait.
Why not A or D: Heterozygous Ee (one of each allele) would result in detached earlobes.
Why not C: If he has no recessive alleles, EE, he would have detached earlobes.
If a boy is born with connected earlobes, he has no E alleles because the allele for detached earlobes is dominant (E), whereas the allele for attached earlobes is recessive (e). So, the correct option is B.
What is Dominant allele?A dominant allele is one that will overpower a recessive allele's expression. Hence, only the trait linked to the dominant allele is manifested when a dominant allele and recessive allele coexist in the genotype of offspring. Consequently, for a recessive allele phenotype to manifest, both of the recessive allele must be present in the progeny.
A recessive allele causes connected earlobes (e) while the dominant earlobe detachment allele (E)
A child with the EE genotype would have disconnected earlobes.
As features of dominant alleles are manifested in heterozygous genotypes, offspring with the Ee genotype would also have disconnected earlobes. Only the child with the ee genotype would have connected earlobes. A homozygous recessive genotype is genotype ee.
Thus, the correct option is B.

Answer
:Photosynthesis can be explained in four simple steps, as follows.
Step 1:
The plant gathers sunlight from the chlorophyll in the cells to convert into energy.
Step 2:
The light energy then reactions and forms hydrogen and oxygen.
Step 3:
The hydrogen joins with carbon dioxide and create sugars.
Step 4:
The sugar is then separated, some to be used as the structure in the cell wall, and some stored in the ATP for later use.

C. All of the trout that live in a lake
D. All of the fish, bacteria, and mammals that live in a lake
SUBMIT
Answer:
Explanation:
First, let’s define population. A population is all of the organisms of the same species that live in a certain area.
Now, let’s analyze the answer choices.
A: All of the different kinds of fish that live in a lake.
This is not a population, because a population is one species, and this is all the different species of fish.
B. All of the living and nonliving things that interact in and around a lake.
This is also not a population. A population is just one species, while this includes all the biotic and abiotic factors.
C. All of the trout that live in a lake.
This is a population. Trout are one species, and it is all the trout in one specific area.
D. . All of the fish, bacteria, and mammals that live in a lake
This is not a population. Fish, bacteria and mammals are too many species for a population.
Therefore, the correct answer is C. all of the trout that live in a lake.
All of the trout that live in a lake is a population of trout. Therefore, option C is correct.
A population refers to a group of individuals of the same species that inhabit a specific geographical area and have the potential to interbreed. A population consists of all the organisms of a particular species that live and interact within a defined area.
Population biology is a branch of biology that focuses on studying populations and their characteristics, dynamics, and interactions. It involves examining factors such as population size, density, distribution, age structure, genetic variation, growth rate and changes over time.

Which is part of the nonspecific immune response?
O A. Fever
O B. B cells
O C. Lymphocytes
O D. Making antibodies
Answer:
A. Fever
Explanation:
Fever is part of the nonspecific immune response. Therefore option A is correct.
Fever serves as a defense mechanism against infections. When the body raises its temperature, it creates an environment that is less favorable for the growth and reproduction of many pathogens.
Higher temperatures can also enhance the activity of immune cells, such as white blood cells, allowing them to function more efficiently in fighting off the infection.
Fever is triggered by the release of certain chemicals, such as cytokines, by immune cells in response to the presence of pathogens.
These chemicals act on the hypothalamus in the brain, which regulates body temperature, causing it to increase.
Thus, fever is a physiological response of the body to infection or inflammation and is considered a part of the nonspecific immune response.

Trees with light brown bark dominate an ecosystem. The ecosystem has populations of insects that thrive on the tree bark. Over time, some insect species developed certain physical characteristics that helped them thrive on the tree bark. These physical characteristics also helped the insects defend themselves from predators. Which insect species is probably the species with the new physical characteristics?
I'm assuming this is referring to the Peppered Moth, a species of moth that adapted to the change of color on tree bark. The tree bark changed color as a result of local pollution. The moths (over the course of generations) changed color as well that better suited camouflage upon the new color of the tree bark.

What is the process of weathering?The process in which break down or disintegration of rock surface occurs due to natural occurring process like rains, snow, wind, or sunshine, is called as weathering.
The origin of weathering may be due to continuous biological, chemical, and physical processes on rocks, wood, soils surface or it may due to soil erosion which occurs with the movement of rocks, minerals, snow, wind etc.
Other physical factors include pressure where as one of the chemical factor include carbonation occur between water and carbon resulted in dissolving rocks area.
When rain water combines with carbon dioxide form carbonic acid, which is then reacts with calcium carbonate of rocks and minerals leads to rock weathering.
As the process of carbonation occur in presence of water, Hence Thus option D is correct.

Distinguish between causal and correlational relationships, with specific examples of how the impacts of group behaviors illustrate these relationships
help me
Answer: The casual relation is a cause and effect relation whereas the correlation is when the two variables are related based on two or more parameters.
Explanation:
A casual relationship can occur in between the two events, the first occurs before the other. The first one is cause and the other one is effect. A correlation can be defined as the relation between the two variables. It does not imply causation. It can be defined as the causal relation between the two variable that are correlated.
Answer:
The difference between causal and correlational relationships is as following:
A correlational relationship is defined as a measure of relationship between two variables and the variables can be negatively correlated, positively corelated or not correlated at all.
Relation between two events said to be causal relation, if the occurrence of the first causes the other. It means the effect of second event should be caused by the the first event.
So, causal relationship between two variables must be correlated.
For example: there is a positive correlation between the organisational behaviour and work done. if any one employee will deny to work from the group of 4 employees it will affect other employees behaviour and reduces their working ability, which will reduce tehir work done. It means that organisational behaviour between employees is the cause of less work done. so, the second event (work done) is the cause of first event (organisational behaviour) and they both are positively correlated as well.
