Answer: The SA node
Answer choices are:
A. The AV node
B. The SA node
C. The purkinje fibers
D. The AV bundle

Energy in most ecosystems must flow through autotrophs because ______.
Energy in most ecosystems must flow through autotrophs because only autotrophs can convert solar energy in chemical energy.
Explanation:
This suggests that these are organisms which are entirely based on the Greek name self-producers that can produce complex organic materials by fixing together simple building blocks in their local situation. E.g plants on land. Photosynthesis in plants transforms solar energy into chemical energy using electrons and protons from water. The method of photosynthesis in plants involves a series of steps and reactions that use solar energy, water, and carbon dioxide to produce organic aggregates and oxygen.

Consider the cladogram. mc014-1.jpg Which group of organisms has the derived characteristics of true tissues, bilateral symmetry, and a pseudocoelom
sponges
roundworms
annelids
chordates
The right answer is roundworms
In the scientific sense, worm refers to the primitive form of organization of the Bilaterians. The three groups of animals (roundworms, flatworms and ringed worms) have a fundamental bilateral symmetry. Their appearance, probably at the very beginning of the Cambrian (primary era), marks an important stage in the evolution of living beings. In spite of their apparent simplicity, they inaugurate a new type of anatomical organization which will then be taken over by all other animal species. The different tissues or specialized organs, come from one of the three embryonic leaves (endoderm, mesoderm and ectoderm) inaugurated by these verses.

what is the difference between a sceintific theory and a scientific law
Answer:
A scientific theory is a set of concepts, a scientific law is a constant and unchanging rule and norm.
Explanation:
A scientific theory is a set of concepts, including abstractions of observable phenomena and quantifiable properties, together with rules (scientific laws) that express the relationships between observations of such concepts. An example of this is the theory of relativity.
A scientific law is a scientific proposition that affirms a constant relationship between two or more variables or factors, each of which represents a property or measurement of specific systems. An example of this is Newton's Laws.
Describe the function of the structure pictured below.
a. Spore production
b. Food absorption
c. Water uptake
d. Enzyme release
Spores are the reproducing body of an organism. Option A is correct. The function of the structure in the given picture is spore production.
Spores:
Spores are the reproducing body. They are found in the lower organisms such as Fungi, algae, and lower plants.
Spores can be Haploid or Diploid depending upon the life cycle.
In the picture, The lower blob-like structure is a stalk that produces spores and a small ball-like structure is spores.
Food is absorbed inside the stomach. Enzymes are released from the cells.Therefore, the function of the structure in the given picture is spore production.

How can karyotype analysis detect genetic disorders lab 12-2 answers?
Karyotype enable viewing of the physical attributes of chromosomes. When compared to the karyotype of a normal individual, any abnormalities in chromosomes can be identified by either noticing an abnormal number of chromosomes or pairing (aneuploidy), or regional changes within chromosomes such as shorter or longer than normal chromosomes due to translocations.

Members of the Protista kingdom contain multi-celled organisms such as kelp and single-celled organisms such as .
Answer:
The correct answer will be Paramecium.
Explanation:
Protista is a heterogeneous group of simple eukaryotic organisms which did not arise from a single ancestral protist.
The members of protist are polyphyletic, which means they are not closely related to each other and do not share many common characters. They vary greatly in organization from single-celled to synctial to multi-cellular organisms.
The most common single-celled protista is Paramecium.
Paramecium are unicellular protist found in freshwater habitats, shaped like a sole of a shoe with short hairy structures on its body called cillia. Cillia helps in locomotion and dragging the food to its oral cavity.
Thus, Paramecium is the correct answer.
Why are all of the organs in the alimentary canal important in digesting food? As food passes through each organ, different hormones are produce to help break it down so that our body can easily absorb nutrients. Each organ has the same role in digesting food but is necessary in order to efficiently break food. The human body needs a long time to digest food in order to be able to absorb nutrients.
