Symbiosis is the relationship of 2 organisms. The 3 major types are commensalism, mutalism, and parasitism. Hope that this helps!

Symbiosis is close relationships between species.
The three types are Mutualism, Commensalism, and Parasitism.

Mutualism is a symbiotic relationship in which both organisms are helped.
For example, butterflies and flowers. The butterflies get food and the flowers get pollinated.

Commensalism is a symbiotic relationship where one organism benefits whilst the other remains unaffected.
An example of this is remora and sharks. Remora attach themselves to the sharks to protect itself and to get food by eating the leftovers of what the shark has eaten. Meanwhile, the shark doesn't care. It isn't hurt but it isn't harmed.

Parasitism is a symbiotic relationship in which one of the organisms benefits by harming the other.
An example of this is ticks and dogs. The ticks gain nutrients by taking nutrients from dogs (and other animals). The ticks are helped and the dogs are harmed.

How did land whales eventually became aquatic?

cluponka [151]

Explanation:

To swim, they move their tails up and down, rather than back and forth as fishes do. This is because whales evolved from walking land mammals whose backbones did not naturally bend side to side, but up and down. ... Whales do the same thing as they swim, showing their ancient terrestrial heritage.

Cetaceans are fully aquatic marine mammals belonging to the order Artiodactyla, and branched off from other artiodactyls around 50 mya (million years ago). Cetaceans are thought to have evolved during the Eocene or earlier, sharing a closest common ancestor with hippopotamuses.

Scientists use DNA sequencing to understand relationships among life on Earth. The chart illustrates differences between five sp

OlgaM077 [116]

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:

<em>The DNA sequences may vary but the amino acid sequences are identical. </em>
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 <u>genetic information contained in the DNA varies from one species to another</u>, 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.

alexandr1967 [171]

Answer:

More than one of the above

Explanation:

I strongly recommend sticking with the prescribed dosage of a drug.

A drug works by binding itself to the receptor site of a cell or tissue by non-covalent interactions.

Repeated doses of the same drug however may make the drug start behaving as an inverse agonist by blocking (instead of binding) the receptor site of the cell thus inducing a reduced response instead of an increased response to the drug.
