It covers the top of the body and encloses the internal organs. Most mollusks have a distinct head region. The head may have tentacles for sensing the environment and grasping food. There is generally a muscular foot, which may be used for walking.
Which of these is a distinguishing characteristic between the domains Bacteria and Archaea?
Answer:
This question lacks options, the options are:
a. Their size
b. The chemical composition of the cell wall and cell membrane
c. Their ability to grow at high temperatures
d. The shape of their mitochondria
The answer is B
Explanation:
Living organisms has been classified into three domains namely; Eukarya, Archaea, and Bacteria. However, domians Archaea and Bacteria are most similar in the sense that they both have cells without a membrane-bound nucleus, hence, they are both PROKARYOTIC. Also, they are both strictly unicellular organisms.
Despite these similarities, differences exists between them. One major difference is in the chemical composition of the cell wall and cell membrane. The cell walls of bacteria cells have a unique structure called PEPTIDOGLYCAN. This is absent in the Archeae group. Also, the cell membrane of Archeae is made up of ether linked lipids compared to the ester-linked lipids that constitutes bacteria cell
Describe Genotypic Species Concept
Answer:
Genotype is the collection of genes responsible for the various genetic traits of a given organism. Genotype refers specifically to the genes, not the traits; that is, the raw information in an organism's DNA. Genotype is determined by the makeup of alleles, pairs of genes responsible for particular traits.

Which type of cell have membrane bound organelles?
prokaryotes
Or
eukaryotes
Answer:
eukaryotes
Explanation:
Like a prokaryotic cell, a eukaryotic cell has a plasma membrane, cytoplasm, and ribosomes. However, unlike prokaryotic cells, eukaryotic cells have: a membrane-bound nucleus. numerous membrane-bound organelles (including the endoplasmic reticulum, Golgi apparatus, chloroplasts, and mitochondria)
Eukaryotic cell have membrane bound organelles. Thus, the correct option is eukaryotic cell.
What is eukaryotic cell?The eukaryotic cell is known as the fully developed and it contain membrane bound organelle. The multicellular organism are made up of the eukaryotic cell and they contain cell organelle it contain mitochondria, ribosomes, RNA, DNA, golgi appratus, and nucleus as well as other cell organelles.
Multicellular organisms are made up of eukaryotic cell and the eukaryotic cell is consist of different cell organelles to carry out different functions in the cell. The multicellular organisms perform different life process in different cells because they have specific cell for specific function.
Amoeba has known as an unicellular organism in which all the activities related to life carried out in a single cell. The example of multicellular organism is human beings and other animals as well plants are also came in the category of multicellular.
Therefore, Eukaryotic cell have membrane bound organelles. Thus, the correct option is eukaryotic cell.

which part of the carbon cycle breaks down carbohydrates into carbon dioxide and water
Resipration
Ersion
Decomposition
Answer:
Respiration
Explanation:
Respiration is a component of the carbon cycle which breaks down carbohydrates into carbon dioxide and water.
Respiration is an aerobic process that takes place in the presence of oxygen.
It is a catabolic process in which energy rich compounds are broken down. In this process, oxygen combines with carbohydrates to produce carbon dioxide and water with the release of energy. Carbohydrates is rich and embedded with energy.Cellular respiration is the process that releases energy for living organisms.

Explain the role that sponges have in the environment
Answer:
Sponges collect bacteria when they filter the water around them. ... They may also be able to turn ammonium from the sponge's breathing into nitrogen gas that is then released into the atmosphere. This process would lower excess nitrogen levels in coral reefs, also preventing harmful ecosystem changes.
Explanation:
Answer: sponges have a role in the environment because they suck up the water or liquid.

Why do you think plants and animals have different types of cells?
Answer:
cause plants do not move from there places and need to make there own food so he can survive.. that is why they need a cell with all necessary and animals can hunt or eat plants which means he just need the cells to produce energy and movements
Explanation:
Plants and animals have different types of cells because they possess different characteristics, modes of nutrition, adaptation, metabolic activities, etc.
What are Plant cells?Plant cells may be defined as the type of eukaryotic cell that has a well-defined nucleus and other membrane-bound cell organelles. These cells are the basic unit of life in organisms of the kingdom Plantae.
Animal cells are also of eukaryotic nature but both shares a huge difference in the composition and manufacturing of cells. Plants have to synthesize their own food with the help of sunlight so they possess chloroplast while animal cells are of the heterotrophic mode of nutrition where they derive their food from plants and their products.
Plants are typically immobile in nature so they have required some sorts of cells that provide them stability in their survival. While animals need some motility cells like bones and other tissues that provide the movement.
Therefore, on the basis of structural dissimilarities, mode of nutrition, adaptation, metabolic activities, etc. plants, and animals have different types of cells.

Explain how soil formation is helped by biotic components through primary succession.
Answer:
Please find the explanation below
Explanation:
Primary succession is a type of succession that occurs in an area with no previous community. It usually contains bare rocks, which are grown upon by certain living organisms (biotic components) called PIONEER SPECIES. These organisms, which include lichens and mosses, colonize the bare rocks and contribute to the formation of soil by the gradual disintegration of the rock particles.
These biotic components (living organism) also help to enrich the soil being formed as they add organic matter, which serve as nutrients, when they die and decompose. The actions of these living organisms on the formation of soil enables other organisms to easily colonize the area.
