8 incisors. 4 canines, also called cuspids. 8 premolars, also called bicuspids. 12 molars, including 4 wisdom teeth.
Human: deciduous teeth: 212/212; adult = 2123/2123. Both childhood molars are replaced by adult premolars. Adult total is double the formula = 32. Opossum: 5134/4134 (one less incisor on each side of the lower jaw).
HOPE THIS HELPED
[tex]\huge\bold\red{Answer:-}[/tex]
The dental formula represents the arrangement of teeth in each half of the upper and the lower jaw. The entire formula is multiplied by two to represent the total number of teeth.
The dental formula for milk teeth in humans is:
[tex] \frac{2102}{2102} = 2[/tex]
Each half of the upper jaw and the lower jaw has 2 incisors, 1 canine, and 2 molars. Premolars are absent in milk teeth hence the zero.
The dental formula for permanent teeth in humans is:
[tex] \frac{2123}{2123} = 32[/tex]
Each half of the upper jaw and the lower jaw has 2 incisors, 1 canine, 2 premolars, and 3 molars. An adult human has 32 permanent teeth.
ʜᴏᴘᴇ ɪᴛ ʜᴇʟᴘꜱ.❤A student wants to illustrate the number of each different bird species that migrates south in winter. Which type of chart/graph would be the most appropriate to use?
a
Pie Chart
b
Bar Graph
c
Line Graph
Answer:
bar graph
Explanation:
A bar graph
You want to show that there is no connection between one species and another.
The line graph will do exactly the opposite. It will imply that the line joining 2 points gives some connection between one point and the next point.
The Pie chart is usually used to compare one number size with a another, like the total number of Covus 19 by state each state close to the other. It is not a good choice because California (for example) might have the most number of cases of the virus but it also has the largest population. You might use the pie chart by converting it to %s, but what would that give you, and how could you use it.

Water molecules being attracted to other molecules (not water) is an example of?
Answer:
In cohesion, water molecules are attracted to each other (because of hydrogen bonding), keeping the molecules together at the liquid-gas (water-air) interface, although there is no more room in the glass.
4. Distinguish between the types of scientific
investigations. Does all scientific knowledge
come from experimentation? Explain your
answer. SC.7.N.1.3
Answer: Descriptive, Comparative and Experimental (which comes from experimentation).
Explanation:
There are three types of scientific investigations:
Descriptive: This type of scientific investigation studies parts of a system, which can be natural or artificial. It describes everything that is being studied and no predictions are made. There are three types of descriptive methods: case-study methods (an in-depth study is produced from many sources with different methods), observational methods (no questions asked, just an observation of the behavior of a subject and no manipulation of the variables), and survey method (some people are interviewed and the researchers study the answers.)Comparative: It gathers information from organisms, systems, places or from any source, to compare them using also a control group. But, there is no imposed treatment because it is not ethical or because it is not possible. So, the treatment is only observed.Experiment: As its names says, it uses an experimental test designed to study some phenomena, where variables are controlled so the treatment is not only observed as the comparative method. Then those variables are measured to collect information or evidence that supports or not a previous hypothesis and is used to assess theoretical knowledge. The independent variable is manipulated while the dependent variable is measured. This type of scientific investigation comes from experimentation.1) Which of the following types of heterotrophs eat other animals?

Which most accurately describes the basis of the scientific method? A.) a path of clearly defined steps that must be followed in a particular order B.) a possible answer to a scientific question based on knowledge or research C.) the recipe for how to conduct an experiment that must be followed precisely D.) the process of hypothesis and testing through which scientific inquiry occurs
The statement 'the process of hypothesis and testing through which scientific inquiry occurs' most accurately describes the basis of the scientific method.
The scientific method is a series of sequential steps used to build scientific knowledge.The steps of the scientific method include:
To make observations about a given phenomenon of the natural world and formulate questions based on these observations.To pose a plausible explanation (i.e., a hypothesis) in order to answer these questions.To test the working hypothesis by experimental and/or observational procedures.To collect data in order to confirm or reject the working hypothesis.Examine results and draw conclusions.In conclusion, the statement 'the process of hypothesis and testing through which scientific inquiry occurs' most accurately describes the basis of the scientific method.

Pollen grains are formed in the anther of the flower by which sequence of events?Haploid microspore mother cells divide by mitosis to form four diploid microspores. Each microspore develops into a pollen grain by meiosis. Diploid microspore mother cells divide by meiosis to form four haploid microspores. Each microspore develops into a pollen grain by mitosis. Diploid megaspore mother cells divide by mitosis to form four diploid megaspores. Each megaspore develops into a pollen gram by meiosis. Diploid microspore mother cells divide by mitosis to form four haploid microspores. Each microspore develops into a pollen grain by meiosis. Haploid microspore mother cells divide by meiosis to form four diploid microspores. Each microspore develops into a pollen grain by mitosis.
Answer:
Diploid microspore mother cells divide by meiosis to form four haploid microspores. Each microspore develops into a pollen grain by mitosis.
Explanation:
Pollen grains contain the male gametes of a sexually reproducing plant. Pollen grains are haploid cells in nature produced by the meiotic division of microspore mother cells (located in the anther). The meiosis of these diploid (2n) microspore mother cells give rise to four haploid microspores. This process in plants is called microsporogenesis.
Each haploid microspore (n) develops into pollen grain called microgametophye (bearing male gamete) via mitotic division. During the pollen grain formation, a wall is formed around the microspores.
Which of the following types of cells suppress immune responses?a. Neutrophilsb. Plasma Cellsc. Macrophagesd. Regulatory T Cells
Answer:
The correct answer is d.
Explanation:
Regulatory T-cells are a class of T cells which are part of the immune system that suppresses immune response. They are called regulatory because they assist in "checking" the excesses/overreaction during immune response.
NOTE:
Neutrophils are phagocytic in nature; they ingest and destroy microorganisms or other foreign molecules.
Plasma cells synthesize antibodies which are produced in response to antigens. They are target foreign particles for digestion by other immune cells.
Macrophages are also phagocytic in nature usually found at sites of an infection.
Which of the following is a biotic factors in an ecosystem? O sunlight O nutrients in soil and water O precipitation O microorganisms
Answer:
microorganisms
Explanation:
Biotic factors include fungi,algae,bacteria etc.
While, Abiotic factors include soil, water ,sunlight and minerals
Answer:
[tex]\boxed {\tt D. \ Microorganisms}[/tex]
Explanation:
A biotic factor is a living thing in an ecosystem. For example: deer, rabbits, grass and trees are all biotic factors.
An abiotic factor is a nonliving thing in an ecosystem. Some examples include rocks, soil, and water.
Let's examine our answer choices.
Sunlight, nutrients, and precipitation are all nonliving, so they are abiotic factors. They can't be the correct choice.
That leaves: microorganisms. Microorganisms are very tiny organisms, like bacteria and amoebas. They are biotic factors, so the correct choice is D. microorganisms
