Answers

Answer 1

Answer: The question is incorrect, below is the correct question

Which DNA FINGERPRINTING technique examines the length variation of DNA repeat sequences in human DNA?

The correct answer to the question is option D

mtDNA (mitochondrial DNA) analysis

Explanation: DNA fingerprinting technique is a laboratory technique used by geneticists.it entails placing of DNA samples into wells,these wells are then placed in a slab of gels and thereafter passing a current through the gel.This is done to ascertain the uniqueness of a DNA pattern and thus be able to differentiate people of same species.

There are several methods of DNA fingerprinting as outlined in the options given with the question.

In mtDNA (mitochondrial DNA) analysis,The Genetic samples are extracted from the biological materials, these samples extracted are total genomic DNA like hair,tooth or samples of blood, Several copies of these genomic DNA are then produced using a polymerase chain reaction and flanking primers inorder to examines the length variation of DNA repeat sequences in human DNA.

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.

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.

Answer:

B. Ants and grasshoppers

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.

Explanation:

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.
