2. In the example of the white and brown mice, vultures will prey on both colors of mice. However, in
the desert environment, the brown mice are better able to hide from their predators and have an
advantageous trait. What will happen to the color of mice over time?

Answers

Answer:

The brown color of mice would become more common in the population of the mice in the desert overtime

Explanation:

In the mice population, since the environment favors the individuals with brown fur color over individuals with white fur color, as it makes them better able to escape from predatory vultures, white mice gets eaten more often. With time, the population of white mice reduces while that of brown mice increases.

Overtime, brown mice leaves more offspring with its trait compared to white mice. As a result of this, the color mice that would be more common in the desert environment would be mainly brown colored mice, while white mice would be few.

A plant with variegated (two-coloured) leaves was left in the sun for several hours. A piece of one of its leaves were then detached (removed) and tested for sugar.

Explain, as fully as you can, why the yellow region of the leaf had not produced sugar. (5 marks)

Answers

Answer:

The yellow leaf was not exposed to the sun so it can't produce sugar.

Kai has a see-through glass tank with air, plants, and animals that eat those plants. He sealed the tank so no material can get into or out of it, but light can get in when the tank is not covered.


The light for the tank has been on all day, and Kai measured the carbon in the air and found that it is decreasing. How is carbon moving between the air and the living things in the tank? What is happening to the amount of carbon in living things? Explain your thinking as completely as possible.

Answers

Answer:

1. Carbon is moving from the living things in the tank into the air when they respirate, and from the air back into plants via photosynthesis

2. The amount of carbon in living things is increasing as plants use the carbon in the atmosphere, and animals eat the plants.

Explanation:

According to the question, a well sealed tank contains air, plants and animals. Since light can get into the tank, plants can perform photosynthesis. Living things in the tank release carbon in form of carbondioxide (CO2) gas through respiration. Plants then make use of this carbondioxide (CO2) to synthesize carbon-containing food (glucose) in the presence of sunlight. This process is called PHOTOSYNTHESIS.

Animals eat those plants and the stored carbon in the plants gets transferred to them. The animals release this carbon into the air again in the form of carbondioxide when they respire. Hence, carbon in the tank moves from the living things (respiration) into the air and back into plants (photosynthesis).

2. Since the amount of carbon in the air is decreasing, the carbon is being used by the living things in the tank. Plants absorb the carbon in the atmosphere for photosynthesis, then animals eat the plants to get the carbon. Therefore, the amount of carbon in the living things is increasing.

1. Carbon is flowing from the living organisms in the tank into the air by the process of respiration and from the surrounding back into plants via photosynthesis.

The animals in the tank utilize the oxygen when they inhale while during exhalation carbon dioxide is liberated.

The carbon dioxide in the tank is used by the aquatic plants to produce food and energy in this way the level of oxygen and carbon dioxide is maintained in the tank.

2. The quantity of carbon in living, are expanding as plants use this carbon in the process of photosynthesis from the environment and animals consumes those plants.

The deposited carbon in the food gets spent by the animals and they release this carbon back via exhalation.

Therefore the quantity of carbon in living things is increasing.

Which types of bacteria does the Monera Kingdom consist of ?

Answers

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.

Analicen el cariotipo humano y den dos ejemplos de pares de cromosomas metacéntricos, dos ejemplos de pares telocéntricos y dos ejemplos de pares acrocéntricos.

Answers

Analyze the human karyotype and give two examples of pairs of metacentric chromosomes, two examples of telocentric pairs, and two examples of acrocentric pairs.

Answer: The test that is conducted to evaluate and identity the shape,size and number of chromosomes in cells of organism is called the Karyotype.

Metacentic chromosomes   are X -  shaped chromosomes. They have centromere at the middle, which makes the arms of the chromosomes equal in length. Therefore any type of chromosomes with equal length of arms is said  to be Metacentic.  Thus  chromosomes  on position  1,13, 16 , 19  and 20 are examples.

When a pair of chromosomes showed  a regular segregation at anaphase  of meiosis, they are said to be telocentric. They are type of chromosomes in which the centromere are located  at the terminal ends of the chromosomes, with the telemeres extending from theses ends.Hence during segregation, the ends of  telocentric chromosomes are orientated towards the poles of the cells. example is the alphabets ''i'' shaped chromosomes in mice and 29 pairs autosomes  in Angora goats.

When the centromere is located in such a way that one arm lenght of a chromosomes is longer than the other, then this is called acrocentric. Example is chromosome 21 of down syndrome.others are 13, 14, 15, 22, and Y-chromosomes.

Explanation:

Looking at the partial Texas food web that is given below in the diagram attached, it shows that the Texas horned lizard feeds mainly on ants and grasshopper as a secondary consumer in the food web. As a result of this, the population of ants and grasshoppers would be often put in check and regulated.

However, if a disease suddenly reduces the population of the Texas horned lizard, it means that ants and grasshoppers won't be heavily preyed on anymore, since the population of their major predator has now been reduced.

Therefore, a reduction in the population of Texas horned lizard would result in the increase in the population of ants and grasshoppers.
