Document Summary

In contrast to the bacteria, archaea, and most microbial eukaryotes, all animals are multicellular. Animal life cycles feature complex patterns of development from a single-celled zygote into a multicellular adult. plants, all animals are heterotrophs. Animals are able to synthesize very few organic molecules from inorganic chemicals, so they must take in nutrients from their environment. heterotrophs. In contrast to the fungi, however, animals use internal processes to break down materials from their environment into the organic molecules they need most. Most animals ingest food into an internal gut that is continuous with the outside environment, in which digestion takes place. plants, most animals can move. Animals must move to find food or bring food to. Animals have specialized muscle tissues that allow them to move, and many animal body plans are specialized for movement. Animal monophyly is supported by gene sequences and morphology.

Related Questions

In general animals are identified as being multicellular, heterotrophic by digestion and reproducing sexually.

Within the Kingdom Animalia we use different features to classify organisms.

One of the main criteria we use in classifying animals is their coelum or body cavity.

What is the purpose of a coelum and why is it so important?

Explain the difference between an Acoelomate, Pseudocoelomate and Coelomate animals.

Give examples of each.

Thanks in advance!

Which of the following statements is true?

Question 7 options:

	In plants, gametes are produced by meiosis
	In animals, gametes are produced by mitosis
	Plants have both a multicellular diploid stage and a multicellular haploid stage
	Most fungi have a life cycle that includes a multicellular diploid stage.
	Most animals have a sexual life cycle that includes a multicellular haploid stage.

Microbiology Unit 2 Applied and Environmental Assignment Part 1:

Identify Nutritional requirements from Chapter 6 & 14 (and review from chapters 1 & 2)

1. Determine which of the 4 macromolecules require the following elements:

a. Carbon: carbohydrates___ lipids___ proteins___ nucleic acids___

b. Nitrogen: carbohydrates___ lipids___ proteins___ nucleic acids___

c. Sulfur: carbohydrates___ lipids___ proteins___ nucleic acids___

2. The essential elements mentioned above are cycled through cells and the earth in biogeochemical cycles like the carbon cycle, the nitrogen cycle, and the sulfur cycle. Select the correct answer and fill in the blanks to summarize these cycles:

a. Carbon dioxide is taken in from the atmosphere by [autotrophs/heterotrophs] and converted to glucose through carbon ________________. When heterotrophs eat autotrophs they catabolize glucose to make ATP through __________________ and waste carbon is released as ___________.

b. There is plenty of nitrogen available in the atmosphere but it is not accessible to organisms because it is in the form of Nitrogen gas (N2). N2 is fixed by [bacteria/plants/animals] and converted to ammonia (NH3.) NH3 can be used by [bacteria/plants/animals] to build their cells. Next, by consuming food with amino acids, [bacteria/plants/animals] can get access to nitrogen for their own cellular needs.

c. There is also a good quantity of sulfur in dirt, rocks, and the atmosphere. Sulfur cycles between H2S => S0 => SO4 => SH groups in Proteins => back to H2S. Using _________________ respiration, anoxygenic photosynthesis, and chemolithoautotrophy [bacteria/plants/animals] convert H2S and S0 to SO4 which is taken in by [bacteria/plants/animals] and used to build their cells. When [bacteria/plants/animals] eat plants they take in essential amino acids containing sulfur and recycle these to make their own proteins.

d. _________________ break down waste and dead organisms and recycle nutrients back into the cycles.

*The C and N are summarized here: https://youtu.be/2D7hZpIYlCA and https://youtu.be/leHy-Y_8nRs

3. Identify the main metabolic classifications:

A microbe that makes its own food by taking carbon from CO₂ in the atmosphere and its energy from sunlight
A microbe that makes its own food by taking carbon from CO₂ in the atmosphere and its energy from reduced inorganic chemicals
A microbe that eats other organisms to get organic carbon and energy
A microbe that uses organic carbon from others but energy from sunlight

Please help me with my microbiology assignment.
