The earthworm has a closed circulatory system, and there are 3 main vessels: <span>aortic arches, dorsal blood vessels, and ventral blood vessels.

aortic arches: It functions as the heart of the earthworm
dorsal blood vessels: Responsible to carry blood to the front of the body
ventral blood vessels: Responsible to carry blood to the back of the body

The blood flow in earthworm is a closed circulatory system. It has <span>three main vessels that supply the </span>blood<span> to organs: arotic</span><span> arches, dorsal </span><span>and ventral </span>blood vessels.

<span>Dorsal vessel is the main collecting vessel. It sends blood to anterior region where it sends blood to lateral oesophageals and to the heart.</span> Ventral vessel is the main distributing vessel. It sends blood to integument, ventrointestinal, and reproductive organs.

Which feature is found in eukaryotic cells but not in prokaryotic cells? A. plasma membrane B. nucleus C. cytoplasm D. genetic m
kiruha [24]

B is the correct answer

A prokaryote cell has no distinct nucleus with a membrane and neither does it have other specialized organelle.

In a eukaryotic cell, the genetic material is DNA in the form of chromosomes which are found within a distinct nucleus.

Examples of prokaryotes Streptomyces soil bacteria (from which streptomycin antibiotic is derived), Escherichia coli bacterium and Streptococcus bacteria (which causes strep sore throat).

Examples of Eukaryotes include protozoa such as amoeba, fungi, plants, animals and generally all  multicellular organisms.

Compare and contrast bioarchaeology and forensic anthropology. What are their similarities and differences? g
Rina8888 [55]

Answer:

Bioarchaeology is a discipline that studies human skeletal remains in an archaeological investigation; while forensic anthropology refers to the study of human skeletal remains in a criminal case  

Explanation:

Bioarchaeology is a discipline centered on the study of skeletal remains in order to obtain useful information about past societies/civilizations such as, for example, health conditions. On the other hand, forensic anthropology investigates human skeletal remains within a legal and/or criminal investigation. This information may result useful to identify a dead person, find the cause of death, and estimate time since death.

Similarities:

-Both disciplines have a strong biology background (especially in zoology)

-Both disciplines are focused on skeletal analysis

Differences:

-Bioarchaeology is associated with the anthropological study of human societies, while forensic anthropology associated with legal investigations

1. Flowering plants and bees have influenced each other's evolution, providing an example of
Doss [256]

Answer:

1. coevolution

2. abiogenesis

3. Endosymbiont Theory

4. It's estimated that over 99 percent of the species that have existed on Earth at some point in time are extinct today.

5. Coevolution implies that the evolution of one species is dependent on and works in relation to the evolution of another species. This may cause positive or negative impacts and could be beneficial to both organisms or only to one.

6. This theory states that the first building block of life that allowed for reproduction of organisms was the development of self-replicating RNA. This hasn't been able to be fully demonstrated in any science experiment but is based on the idea that there are RNAs that can catalyze biochemical reactions on their own without proteins.

7. This process points to the development of structures through the envelopment of smaller cells that perform specific functions. This is how eukaryotic cells evolved from prokaryotic cells.

8. This experiment was important because it showed that, in the right primordial soup, organic compounds could develop from inorganic compounds.

kotykmax [81]

Answer:

What is perception and its process?

The perceptual process begins with receiving stimuli from the environment and ends with our interpretation of those stimuli.

Organizational Behavior - Perception. Perception is an intellectual process of transforming sensory stimuli to meaningful information. It is the process of interpreting something that we see or hear in our mind and use it later to judge and give a verdict on a situation, person, group etc.

Which of these is also known as the sublittoral zone?
Nataliya [291]

Answer:

b. the neritic zone

Explanation:

Neritic zone, also known as sublittoral zone, is a transition zone between the continental domain and the marine domain. It is the area that is under the influence of the tides and where light can penetrate to the bottom, promoting photosynthesis.

This zone is a complex, dynamic, changeable range and subject to various geological processes. The mechanical action of waves, currents and tides are important modeling factors of coastal zones, the results of which are erosion or deposition.
