Choose the FALSE statement about the space shuttle program. A. It lasted over 30 years. B. It launched the Hubble Space Telescope. C. It conducted scientific experiments in lunar orbit. D. It helped in the creation of the International Space Station.
The space shuttle can only get as high as the low-earth orbit (LEO). This is a few hundred or so miles within the earth's surface. Compare this to the distance from the earth's surface to the moon is about 238,855 miles on average.
According to NASA's website: "It does not carry enough propellant to leave Earth's orbit and travel to the Moon. The Space Shuttle also is not designed to land on the Moon since it lands like an airplane and the Moon has no atmosphere"

Would you expect the plants and animals present in the southeast of the U.S. To be similar or different to that of the plants and animals present in Northeast Africa?
Answer:
Different
Explanation:
The climatic conditions or weather conditions of the southeast of the United States are different to that of the northeast Africa. And because of this, the two zones are not expected to have the same type of animals.
For example, the weather conditions of the southeast of the United States are humid and thunderstorms, while that of the northeast Africa are hot and dry.

Which types of bacteria does the Monera Kingdom consist of ?
Answer:
Prokaryotic Bacteria
Answer:
Monera is a kingdom in biology that comprises prokaryotes, which are single-celled organism that have no true nucleus.Apr 28, 2017
Explanation:
Kingdom Monera
You have suffered from a lot of diseases that bacteria cause. But, do you think all bacteria are bad? No! The bacteria have a huge kingdom of their own that consists of a number of varieties of them. Each bacteria has a different role to play. They belong to the kingdom Monera. Here, we will know all about the kingdom Monera. We will look at both their characteristics and divisions in greater detail.
Characteristics of Monera
Monera (Monos – single) includes prokaryotes and shows the following characters:
They are typically unicellular organisms (but one group is mycelial). The genetic material in these organisms is the naked circular DNA. A nuclear envelope is absent. Both, ribosomes and simple chromatophores, are the only subcellular organelles in the cytoplasm.
Sap vacuoles do not occur. Instead, gas vacuole may be present.
The predominant mode of nutrition is absorptive but some groups are photosynthetic (holophytic) and chemosynthetic.
The organisms are non-motile or move by the beating of simple flagella or by gliding.
Bacteria Shape
Cocci: They are oval or spherical in shape.
Bacilli: They are rod-shaped. They may or may not have flagella.
Vibrios: These are small and ‘comma or kidney’ like. They have a flagellum at one end and are also motile. Vibrio bacteria has a curve in its cell.
Spirillum: They are spiral or coiled like a corkscrew. The spiral forms are usually rigid and bear two or more flagella at one or both the ends e.g., Spirillum, Spirochaetes etc.
Filament: Just like fungal mycelia, the body of the bacterium is filamentous. The filaments are very minute in size. Examples include Beggiota, Thiothrix etc.
Stalked: The body of bacterium possesses a stalk e.g., Caulobacter.
Budded: The body of the bacterium is swollen at places e.g., Rhodomicrobiu
Structure of Bacteria
Capsule: In a large number of bacteria, a slimy capsule is present outside the cell wall. It is composed of polysaccharides and the nitrogenous substances (amino acids) are also present in addition. This slime layer becomes thick, called, capsule. The bacteria, which form a capsule, are’ called capsulated or virulent bacteria. The capsule ‘is usually found in parasitic forms e.g., Bacillus, anthracite, Diplococcus pneumoniae, Mycobacterium tuberculosis.
Cell wall: All bacterial cells .are covered by a strong, rigid cell wall. Therefore, we classify them under plants. Inner to the capsule, the cell wall is present. It is made up of polysaccharides, proteins and lipids. We also find D-glutamic acid and diaminopimelic acid.
Monera
Plasma membrane: Each bacterial cell has a plasma membrane. It is situated just internal to the cell wall. It is a thin, elastic and also differentially or selectively permeable membrane.
Cytoplasm: The cytoplasm refers to a complex and aqueous fluid or semifluid ground substance (matrix). This material consists of vitamins, salts, enzymes, carbohydrates, soluble proteins, co-enzymes, lipids, mineral and nucleic acids. The organic matter is present in the colloidal state.The cytoplasm is granular due to the presence of a large number of ribosomes.
Nucleoid: It has other common names like genophore, naked nucleus or incipient nucleus. There is nuclear material in these, DNA. It is double helical as well as circular. Some kind of typical protein surrounds it. However, these are not histone proteins.
Plasmids: In addition to the normal DNA chromosomes, many bacteria (e.g., E.coli) have extrachromosomal genetic elements or DNA. These elements are plasmids. They are small circular double-stranded molecules.
Flagella: These are fine, thread-like, protoplasmic appendages. These extend through the cell wall and the slime layer of the flagellated bacterial cells. These help in bacteria to swim about in the liquid medium.
Pili or Fimbriae: Besides flagella, some tiny or small hair-like outgrowths are present on the bacterial cell surface. These are pili. They comprise of pilin protein. They consequently measure about 0.5-2 mm in length and 3-5mm in diameter.
Nutrition in Bacteria
On the basis of mode of nutrition, we can group bacteria into two broad categories. First is autotrophic whereas second is heterotrophic bacteria.
Autotrophic bacteria: These bacteria are able to synthesize their own food from inorganic substances, as green plants do. They derive their carbon from carbon dioxide. The hydrogen needed to reduce carbon to organic form comes from sources such as atmospheric H2, H2S or NH3.
Heterotrophic bacteria: Most of the bacteria cannot synthesize their own organic food. They consequently depend on external organic materials. They require at least one organic compound as a source of carbon for their growth and energy. Such bacteria are heterotrophic bacteria. Heterotrophic bacteria are of three types: Parasites, Saprotrophs and Symbionts.

Mammals that live in the Arctic Ocean have a large amount of blubber, which is a fatty tissue just beneath the skin.
Which statement best relates why these animals have so much blubber?
O Lipids in blubber insulate the animals from cold water.
O Proteins in blubber help the animals move to stay warm.
O Carbohydrates in blubber provide all the energy that the animals need to stay warm.
O Nucleic acids help build the lipids in blubber, which keep animals warm by regulating cell activities.
Answer:
Lipids in blubber insulate the animals from cold water.
Explanation:
Lipids are fatty tissue, or fats in the cells. Blubber is fat. The fat helps insulate animals from cold water, especially in the Arctic known for being freezing. Fats can help maintain and keep body heat, hence why skinnier people are colder. Without lipids, they would most likely freeze.
Answer:
Lipids

Which is one way that minerals crytallize from materials dissolved in water
From the air
From solutions that evaporate
From hot water solutions when water boils
From the soil
Answer:
From solutions that evaporate
Explanation:
Minerals can form in different ways. According to the question, minerals crystallize from a material dissolved in water when the solution evaporates. When a material dissolves in water, it forms a solution i.e. water + dissolved material.
The element constituents of the solution can aggregate to form a solid mineral, which will be left to crystallize when the solution undergoes evaporation i.e. liquid changes to gas. A very good example is when salt dissolves in water to form a salt water solution. When the water of this solution evaporates, salt crystals are left, which can crystallize to form minerals.
Answer:
From solutions that evaporate

A scientist has discovered a new plant species in the Amazon rainforest she tells her fellow scientist at the Playhouse she has found for Tuesday is a cone for my side about this plan is different from an organism
Answer:
It is a seeded vascular plant.
It does not depend on insect pollination.
Explanation:
The complete question is: A scientist has discovered a new plant species in the Amazon rainforest. She tells her fellow scientists that the plant she has found produces a cone. What might they say about how this plant is different from an angiosperm? Its seeds have one or two cotyledons. Its stems' vascular bundles are scattered. It does not depend on insect pollination. It is a seeded vascular plant.
The correct option would be that the plant is a seeded vascular plant and does not depend on insect pollination.
Gymnosperms are the only group of plants that produce cones. They are one of the plant groups that have vascular tissues in the form of xylem and phloem as well as been able to produce seed in the form fo cones. Hence, they are said to be seeded vascular plants.
Gymnosperms also carry out their pollination by relying solely on wind for the transfer of their pollen grain to the female organ. In other words, they do not depend on insect for pollination.
