Answer:
INVASIVE species
Explanation:
In biology, an organism is said to be INVASIVE if the organism is foreign to a particular region or habitat and possess the unpleasant ability to proliferate or grow rapidly to the point of competing with local species of organisms.
According to this question, humans are said to introduce organisms that have the ability to harm the local flora and fauna. Hence, these organisms are INVASIVE SPECIES because they are foreign to that place and cause damage in their new environment.

Show different life cycle patterns with the help of near labelled diagram
Answer:
The life cycles of all sexually reproducing plants follow a pattern of alternation between a haploid, sexual generation called gametophyte with a diploid, asexual generation called sporophyte.
This phenomenon of alternation between gametophyte (n) and sporophyte (2n) in the life cycle of a plant is called alternation of generations (Hofmeister, 1851).
Alternation of generations is of two types- isomorphic and heteromorphy. In isomorphic (or homologous) type both the alternating generations are morphologically similar, while in heteromophic (or heterologous) type of alternation of generations both the generations of life cycle are morphologically dissimilar.

Answer:
The RARA gene on chromosome 17 provides instructions for making a transcription factor called the retinoic acid receptor alpha (RARα). A transcription factor is a protein that attaches (binds) to specific regions of DNA and helps control the activity (transcription) of particular genes.
Explanation:
Chromosome 11 is one of the 23 pairs of chromosomes in humans. Humans normally have two copies of this chromosome. Chromosome 11 spans about 135 million base pairs (the building material of DNA) and represents between 4 and 4.5 percent of the total DNA in cells.
Consider the diagram of the basic structure of a bacterium. A diagram of a bacterium is labeled. Part A is the cell membrane, part B is the flagellum, part C is the nucleoid, and part D is the pilus. Which of the labeled structures in the image allows bacteria to exchange genetic material and thus evolve to be better pathogens?
Answer:
Part D: pilus
Explanation:
Conjugative pili allow for the transfer of DNA between bacteria and thus evolve to be better pathogens.
The structure in bacteria that allows them to exchange genetic material and evolve is the pili
Bacteria piliPili (pilus, singular) are thin, proteinous structures located on the surface of bacteria that serves as:
they help bacterial cells to attach to surfacesthey serve as channels for the transfer of genetic materials during conjugationWhen genetic materials are transferred through the pilus, gene recombination occurs and bacteria evolve as a result.

Transcription is the process of mRNA synthesis. It occurs in the nucleus before translation. During transcription, RNA bases pair DNA bases, replacing Thymine with Uracyl. You will find the example in the explanation.
Note: The DNA sequence is missing, so I will provide a new sequence and explain the procedure. I suggest you perform the same steps with your molecule fragment and reach the correct mRNA.
Protein synthesisProteins synthesis is done in two stages: transcription and translation. The whole process begins in the nucleus and finishes in the cytoplasm.Protein synthesis initiates in the AUG start codon -Metionin-, and ends when reaching either of the stop codons UAA, UAG, UGA. Once the new molecule is completed, it is sent to its final destiny.Transcription:The first step before protein arrangement is to synthesize messenger RNA, mRNA. This is the transcription process and occurs in the nucleus. When the DNI molecule separates into two strands to form the transcription bubble, we can identify two separate segments: coding strand and template strand. The coding strand goes in direction 5' to 3', while the complementary strand -template strand- grows in direction 3' to 5'. This last segment is the one that is going to be complemented by the mRNA. It is the template strand. A template DNI strand is read in direction 3'→ 5' to build the mRNA molecule that grows in direction 5'→ 3'.During transcription bases forms pairs. RNA replaces Thymine with Uracyl, so pairs are as follows,DNA mRNA
Adenine pairs Uracyl, Thymine pairs Adenine, Guanine pair Cytosine, Cytosine pair Guanine.Translation:
Translation occurs in the cytoplasm. During translation, rRNA reads mRNA in 5' to 3' direction, and tRNA adds the correct amino acid to the growing chain. The first extreme to be translated carries the amino-terminal group, while the other extreme carries the carboxy-terminus group.ExampleWe will consider for this example the following DNA template strand.
DNI strand ⇒ 5'-TAGAACGCCTCGAAATTTCATACT-3'
Transcription
template DNI strand ⇒ 5'-TAGAACGCCTCGAAATTTCATACT-3'
mRNA ⇒ 3´-AUCUUGCGGAGCUUUAAAGUAUGA- 5´
The new mRNA strand is
mRNA ⇒ 3´-AUCUUGCGGAGCUUUAAAGUAUGA- 5´
Once the mRNA synthesis is over, the molecule leaves the nucleus and proceeds with translation in the cytoplasm.

environmental pressure definition
Environmental pressure, also known as selection pressure or ecological pressure, refers to the influence exerted by the environment on living organisms, driving the process of natural selection.
It encompasses various factors, such as climate, competition for resources, predation, and other ecological interactions.
Environmental pressure plays a pivotal role in shaping the characteristics and traits of organisms within a population.
Individuals possessing advantageous traits that align with the environmental conditions are more likely to survive, reproduce, and pass on these beneficial traits to the next generation.
Over time, this process leads to the adaptation and evolution of species, enhancing their ability to thrive and succeed in their specific ecological niches.

Explain how a symbiotic relationship like the one described in the endosymbiotic theory would have benefited each cell.
Answer:
cannot grow outside their host cell of biolapsy
The symbiotic relationship is a type of relationship in which two organisms living with each other and gives benefit to one another.
Mutualism is a type of symbiotic relationship in which both organisms benefited from one another. In this type of relationship, one organisms is smaller that lives inside the body of other big organisms.
For example, bacteria lives in the nodules of plant's root. The plant provides shelter to the bacteria while on the other hand, bacteria fixes atmosphere nitrogen into available form so in this way both get benefits from one another.

22. Why do you think the sea urchin was chosen to test the effect of changes in pH?
Answer:
as it settles deeper underwater ph tends to be higher and a sea urchin tends to be more resilient to change
Acidic seawater, at current pH levels found in the world's oceans, can have a negative impact on sea urchin larval development so it is taken to test the effect of changes in pH.
What is sea urchin?Sea urchins are spiny, globular echinoderms of the Echinoidea class. The urchins were able to compensate for internal pH in modest acidification (pH 7.8) and not in higher acidification (pH 7.6).
The pH of coelomic fluid was lower at higher temperatures.
Thus, due to this, the sea urchin was chosen to test the effect of changes in pH.
