Which statement is not true of introduced species?

Which of the below statements is correct? Please choose the correct answer from the following choices, and then select the submi

Reil [10]

Answer: The correct answer is option D.

Explanation:

In diploid organism, chromosomes are present in pair. One chromosome is inherited from mother and one from father. The chromosomes pair is termed as homologous chromosomes. They are similar in shape, size, number of genes present, sequence of the genes, position of centromere, et cetere.

Thus, option A is incorrect.

However, the genes may have different allele. For example chromosome 1 (maternal) contains one dominant allele, say T, while chromosome 1 (paternal) contains recessive allele at the same locus, say t,.

So, if an organism contains same alleles for the trait then, it is termed as homozygous for that trait. It can either be homozygous dominant (TT) or homozygous recessive (tt).

Thus, option B and C are incorrect.

However, of an organism contains two different alleles for the trait then it is termed as heterozygous for that trait (Tt). The phenotype is usually resulted from the expression of dominant allele.

Hence, option D is the correct answer.

Anaerobes carry on whereas aerobes carry on cellular respiration

Tcecarenko [31]

Answer:

Anaerobes carry on cellular respiration in the absence of oxygen, whereas aerobes carry on cellular respiration in the presence of oxygen.

Explanation:

Many of the cell processes needed need some energy to occur. Cellular respiration is the process by which cells degrade organic compounds and turn them into energy. Cellular respiration follows two ways, which depend on the presence or absence of oxygen, and both of them begin with the process of glycolysis, which occurs in the cytoplasm and does not need oxygen to occur.

<u>Aerobic Respiration</u>

Occurs in the presence of free oxygen.
Series of reactions by which pyruvic acid (product of glycolysis) turns into CO₂ and H₂O, producing many ATP molecules.
Respiration occurs in the mitochondria.
Takes place in two steps or stages: Krebs cycle and electron transporter chain.
Glycolysis and Krebs cycle produce electrons, which then travel along the electron transporter chain while releasing energy, and ATP is produced.

<u>Anaerobic Respiration </u>

Occurs in the absence of free oxygen
Series of reactions by which using pyruvate (product of glycolysis) 2 ATP molecules van be produced.
There are two ways in which anaerobic respiration can be produced: lactic fermentation and alcoholic fermentation.
Lactic fermentation produces lactic acid and 2 ATP
Alcoholic fermentation occurs in two steps, and the final products are ethylic alcohol, 2ATP, and 2 CO₂
The whole anaerobic process occurs outside the mitochondria.

Simora [160]

Conditioned stimulus

Classical conditioning is a learning procedure in which a biologically potent stimulus paired with previously neutral stimulus. This pairing will cause a response that can be the same as the potent stimulus. This is done repeatedly for an organism to elicit a conditioned response to the previously neutral stimulus that was paired to the active stimulus. The dog salivates due to the idea that food is related to the sound of the bell.

Which relationship is shown in the graph?

podryga [215]

The answer is D as there are fluctuations which means that changes in the population of one affects the population of the other. as prey pop increases predator pop increases leading to a decease in prey pop which causes predator pop to decrease due to lack of food then prey increases and the cycle repeats
