The given statement-Logistic growth curves are density-dependent is True.
Logistic growth curves describe population growth that takes into account density-dependent factors, such as competition for resources and predation.
The logistic growth model assumes that as a population grows, it will eventually reach a point where resources become limited, and the growth rate slows down.
This is known as the carrying capacity of the environment, which is the maximum population size that can be supported by the available resources. Thus, the growth rate of the population becomes dependent on the population size or density. Hence, the statement is True.

The correct answer is true.
The density dependent factors are those factors, which is affect the size of the population.
The logistic growth curve shows a a lag phase, a log phase and a stationary phase. In the lag phase, the growth of the organism is minimal, here it prepare for the growth, in log phase, the population growth is exponential. As the resources in a particular area is limited and carrying capacity is also limited, after a certain population density, the growth become stationary, which means mortality becomes equal to the birth rate. As the logistic curve is affected by the density of the population, it would be density dependent.
P.S.- if the resources are not limited, the population continuous to grow exponentially, and would represent exponential growth curve.
Answer: Polar covalent bond
Explanation:
In ionic compounds, electrons are transferred between atoms of different elements to form ions. But this is not the only way that compounds can be formed. Atoms can also make chemical bonds by sharing electrons equally between each other. Such bonds are called covalent bonds
RNA or Ribonucleic acid is a molecule similar to DNA. It is single-stranded, has nitrogenous base pairs, and a sugar molecule. The RNA can be categorized into mRNA, tRNA, and rRNA.
The correct sequence of nucleotides in the tRNA will be:
U - U - A
In the nucleotide sequencing, the nitrogenous compounds present in the RNA are adenine, guanine, cytosine, and uracil instead of thymine.
The mRNA is a single messenger molecule, which is made from the transcription of DNA molecule. The further process involves the translation in which ribosomes play a crucial role.
In translation, the polypeptide is synthesized by the information delivered by the mRNA. The information in the mRNA is read in the form of a group of three nucleotides, known as a codon.
The codon is then read by the corresponding anticodon region of the tRNA molecule. It makes the set of the anticodon, which is complementary to the codon.
For instance, the mRNA containing the base pairing of A-A-U, the complementary sequence made by tRNA will be U - U - A.
Therefore, the correct answer is U - U - A.
To know more about mRNA and tRNA, refer to the following link:
Answer:
U-U-A
Explanation:
A mRNA molecule is formed as a result of transcription, which then proceeds to the ribosomes in the cytoplasm to undergo translation. Translation is the process whereby an amino acid sequence (protein) is synthesized using the information in the mRNA molecule/sequence. The mRNA sequence is read in a group of three nucleotide bases called CODON. Each codon specifies an amino acid.
This codon is read by another RNA molecule in the ribosome called tRNA (transfer RNA). tRNA contains another set of three nucleotides called ANTICODON, which is complementary to the CODON and responsible for reading the codon in order to carry the corresponding amino acid to the growing sequence.
According to this question, a portion of a messenger RNA molecule contains the base sequence A-A-U, the complementary anticodon sequence of the tRNA would be U-U-A.
