Which level of organization involves an organism’s use of the mouth, saliva, teeth, stomach, intestines, liver, and pancreas to break down food?
A. Cell.
B. Tissue.
C. Organ.
D. Organ system.
The level of organization involves an organism’s use of the mouth, saliva, teeth, stomach, intestines, liver, and pancreas to break down food in the organ system. The correct option is D.
What is the organ system?An organ system is a collection of organs that cooperate to carry out a certain task in the body of an organism. Organs, which are self-contained collections of tissues like the heart that cooperate to carry out a single function, are present in the majority of animals and plants.
The human body is composed of 11 primary organ systems. These include the reproductive, integumentary, skeletal, muscular, nervous, endocrine, circulatory, lymphatic, respiratory, digestive, and urinary systems.
Organ systems are collections of organs that cooperate to carry out a task for the body they are a part of. They can aid in gas exchange, waste removal, nutrient acquisition and transportation, illness sensing, and disease protection for the body.
Therefore, the correct option is the D. Organ system.

A biologist wants to measure the effect of gene flow between populations. Which of the following investigations will allow her to accomplish this goal?
A)An investigation that determines a change in allelic frequency of a wolf population by theimmigration of a wolf from another population.
B)An investigation that determines the amount of time it takes for genes from a bee to transfer to the flower it fertilizes.
C)An investigation that determines the causes of mutations in genes that one species of guinea pig transfer to another species of guinea pig.
D)An investigation that determines the rate at which an antibiotic prevents a virus from transferring genes to a cat.
Answer:
B
Explanation:
Cause I say so
The investigation that will allow a biologist to measure the effect of gene flow between populations is that a change in allelic frequency of a wolf population by the immigration of a wolf from another population. Thus, the correct option for this question is A.
What is Population?A population may be defined as a group of individuals belonging to the same species living in the same area at a given time. The size, density, abundance, birth rate, death rate, dispersal, etc. are categorized as the characteristics of a population. These characteristics are known as demographic factors.
According to the context of this question, the process of gene flow can be determined by collating allele frequencies of populations. With this mechanism, if the two populations have increased variation in their gene pool, it expresses a lesser amount of gene flow because gene flow increases homogeneity among different populations.
Therefore, the correct option for this question is A.

Explain what scientists might be able to learn about the seawater that existed millions of years ago by studying rocks that came into contact with seawater at that time in the past . Use evidence from the text to support your inference.
Answer:
About composition of water and organisms that lives there.
Explanation:
scientists might be able to learn about the composition of seawater that was present millions of years ago if we study those stones that comes in contact to that ancient seawater because the traces of particles still present on it. This study provides valuable information about ancient times of earth and its natural resources. These rocks also provides animals that were present in that sea water at that time.
Geologists using the aspects of geology and paleontology can study and analyze the evolutionary, physiology and ecological relation of plants, animals and other microorganisms with abiotic and other biotic factors.
The scientists will be able to understand the composition of the organism and the water that resided in the region.
This inference can be supported by:
The stones and rocks present in the seawater will depict the characteristics as they will have traces of particles present on them from the past years.This evaluation will provide insights into the natural resources and organisms present during the ancient times on the planet.This will also give data about the organism living in aquatic or terrestrial areas.Therefore, it will give the composition of water and organisms.

Most populations do not experience: ____ va) exponential growth b) Linear growth c) Resources d) Competition
Answer:
Most populations do not experience: a) exponential growth
Explanation:
Populations that experience exponential growth models show an increase in proportion to their size. The increase in the population size depends on the individual´s reproduction rate: a population that grows at constant exponential rate gains individuals faster as the population increases in size.
This model states that populations live in an environment with unlimited resource availability, so the density factor does not influence population growth. There is no density-dependence effect nor competition for resources. Natality and mortality rate do not depend on density. There is a constant growth rate per capita, and it is proportional to the population size.
Exponential growth is hardly seen in nature due to its characteristics.
Almost every environment shows a carrying capacity point. Carrying capacity is the capability of the environment to support a population. Commonly environments have limited resources and space, and as the population grows, competition increases too. The per capita growth rate decreases as population size increases. Finally, the population reaches the maximum point of carrying capacity, delimited by available resources, such as food or space.
The carrying capacity might be affected by limiting factors, which might be a result of the population density (for example, competition) or might be density-independent. This last case refers to dense-independent factors, and among these, we can mention human impact or natural disasters (fires, volcanic eruption, flooding).
Only a few species can experience exponential growth, such as bacterias.

Which statement is accurate about variations?(1 point)
Organisms with variations that give an advantage are more likely to survive.
Organisms with variations are less likely to pass these variations to their offspring.
In all cases, variations become more common in a population.
In all cases, variations affect how likely it is that an organism reproduces.
The accurate statement about variation is that organisms with variations that give an advantage are more likely to survive.
What are variations?Variations are differences that occur between organisms of the same species or of different species.
Variations occur due to differences in the genes of organism.
Variations can be of an advantage or disadvantage to an organism.
Variations that give an advantage to an organism makes it better suited to survive and reproduce.
Therefore, the accurate statement about variation is that organisms with variations that give an advantage are more likely to survive.
