Answer:

Yes, it could have been monazite.

Monazite could have become part of sedimentary rock because it is formed during the metamorphosim of clastic sedimentary rocks. It is a resistant minerals that is found in weathered rocks debris which become concentrated and they are part of the soils and sediments found near weathered rocks.

Explanation:

Monazites are phosphate minerals that are found im small grains as accessory in igneous rocks and sedimentary rocks. It is formed during the crystallization of igneous rock and metamorphosim of clastic sedimentary rocks.

It is a resistant minerals that found in weathered rocks debris and become concentrated in sediments near weathered rocks.

Answer:

A

Explanation:

Answer:

detritus, in ecology, matter composed of leaves and other plant parts, animal remains, waste products, and other organic debris that falls onto the soil or into bodies of water from surrounding terrestrial communities. microorganisms (such as bacteria or fungi) break down detritus, and this microorganism-rich material is eaten by invertebrates, which are in turn eaten by vertebrates. many freshwater streams have detritus rather than living plants as their energy base.

Explanation:

Xylem are stronger and thicker tubes than the Phloem, and the Xylem are meant to bring nutrients and water from the roots too the leaves!

Phloem are much smaller, and much more brittle than the Xylem, and they also have a different job. These are meant to take the glucose made from photosynthesis and move it to the rest of the plant. These are made up of tubular cells, creating a vascular system.

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.

Answer:Bats are not blind and can in fact see quite well using their eyes. While most bats do have advanced ears that give them a form of vision in the dark known as echolocation, these good ears does not require them to have bad eye

Answer:

They would live in salt water.

Explanation:

Salt water is a hypertonic solution where water needs to move outside of the cell because there is too much solute outside. Because the 2 organisms are removing excess water, it shows that they are living in salt water where water flows outside instead of inside the cell.

Based on the available information, these two organisms would:

According to the given question, we can see that there is a need for survival which makes a single celled organism to make use of the vacuole to remove the excess water which it diffuses into its cell.

As a result of this, we can see that another specie, a hydra also excretes excess water which involves the use of energy.

Therefore, the conclusion we can reach about them is that they are living in salt water because it is a hyper tonic solution which allows water to move freely outside the cell because of the excess solute outside the cell wall.

Answer:

gymnosperms produce male cones and female cones, and the pollen from a male cone fertilize the egg inside a female cone

Answer:

Natural selection occurs when some of those traits help some individuals survive and reproduce more than others. That causes their genes to become more common in the population over time, and it's the way species evolve to adapt to changes in their environment.

Continental drift theory

Explanation:

Continental drift theory refers to the movement of land masses over the earth's geological time. This movement n of the masses of the earth allows us to conclude that the continents change their shapes over time and change, including their location in different regions of the planet.

As we already know the movement of the masses of the earth is done in relation to the movement of the tectonic plates.

Answer:

100 percent Ee

Explanation:

This is a cross involving a single gene coding for attachment or not of earlobes. The allele for unattached earlobes (E) is dominant over the allele for attached earlobe (e). This means that allele E will always mask the phenotypic expression of e in a heterozygous state.

A parent that has same alleles for unattached earlobes i.e.  EE is crossed with a parent that has same alleles for attached earlobes i.e. ee. In this cross, all of the offsprings will have a heterozygous genotype, Ee because gametes E and e will be produced respectively by each parent.

Hence, since all of the offsprings will have an Ee genotype, it means 100% of their offsprings will have Ee (HETEROZYGOUS).
