What is the difference between active transport and diffusion in terms of movement of particles?

1 answer:

7 0

Active transport is the movement of dissolved molecules into or out of a cell through the cell membrane, from a region of lower concentration to a region of higher concentration. The particles move against the concentration gradient, using energy released during respiration.

Answer:

With respect to the differences in the DNA sequence of six species, including the human one, it is true that the DNA sequences may vary but the aminoacid sequences are identical.

Explanation:

Options for this question:

The DNA sequences may vary but the amino acid sequences are identical.
The nitrogen bases in the nucleotides must also be different in each.
The process in producing additional DNA, replication, is identical in all six.
The process of producing DNA, or replication, varies due to the differences in the DNA codes.

The different species that exist have specific genomes for each of them, this is the genetic information contained in the DNA varies from one species to another, as can be seen in the scheme (see image). However, the genetic code is universal, and does not vary from one species to another.

The genetic code is found in the RNA molecule and is a sequence of nucleotides that, organized in triplets (codons), are responsible for the synthesis of specific amino acids. An RNA molecule contains the information necessary for protein synthesis.

The scheme shows the differences of five species with respect to the human, based on the respective DNA sequences. But what it does not show is a universally accepted truth, that the nucleotide sequence encoding an amino acid is the same for each of these species.

kirill [66]

The snakehead could unreservedly eat little fish and scavangers, so that would evacuate/diminish the predator for zooplankton and phytoplankton. So zooplankton and phytoplankton populace would increment while little fish and scavanger populace would diminish. Presently if little fish and shellfish populace diminishes, their predators would have bring down sustenance, so vast fish pop. would diminish. On the off chance that vast fish pop. diminishes, their predators will have less nourishment thus the number of inhabitants in well evolved creatures will somewhat drop, however not by much, since they can feast upon zooplankton.
So at last, just the phytoplankton populace would increment while everything else diminishes.

Answer:

Allele

Explanation:

Genes come in multiple forms, or versions. Each of these forms is called an allele. For example, the gene responsible for the hair color trait has many alleles: an allele for brown hair, an allele for blonde hair, an allele for red hair, and so on.
