4 0

Invasive species can either replace an organism from the ecosystem food web or replace it.  

Explanation:

  • Invasive species are non-native species which can be animals, plants, micro-organisms, fish, etc. they are very much threatening to the native species and ecosystem food web.
  • Invasive species are spread by humans mostly, it happens unintentionally when people travel and all. Even climate change could be a reason for its spread.
  • So, it becomes threatening to native species because when you introduce it into a new ecosystem, it does not have a predator or control. It grows aggressively and takes over the resources for the native species.

The cell cycle
tankabanditka [31]

Answer:The cell cycle a. includes mitosis as an event.

Explanation:

The cell cycle consists of two stages:

interface and phase M (mitosis). In the first, the cell grows and doubles its DNA; It consists of phases G1, G2 and S. In phase M, the cell divides its already duplicated DNA and the cytoplasm divides into 2 (cytokinesis), forming 2 daughter cells. There is a G ° phase, where the cell is in a "vegetative" state, called "senescence." The cell cycle is regulated cyclin / CDK complexes, tumor suppressor genes (example: p53).

3. If a daughter has an X-linked recessive disorder, such as color-blindness, she inherited the
Lubov Fominskaja [6]

Answer:

She inherited the trait from C: both parents.

Explanation:

The daughter, being female, has the chromosomes XX. Since the disorder is <em>recessive</em>, both of the chromosomes need to have the disorder's allele in order for it to activate. The daughter's chromosomes can be labeled as X(c)X(c); where the c stands for the color-blindness allele. She needs one X chromosome from the father, and one X chromosome from the mother. Both of these chromosomes contained the (c) allele, as said before, so the mother has one X(c) and the father has one X(c). This means that she inherited the trait from both parents. The final answer is C.

If you wanted to sequence the genome of Ötzi, the 5,300-year-old "Iceman" mummy found in the Alps in 1991, which method would yo
Delvig [45]

The question is incomplete as it does not have the options which are:

a) DNA

b) AGCT

c) PCR

d) SNP

Answer:

PCR (polymerase chain reaction)

Explanation:

The polymerase chain reaction is the technique which replicates and produces multiple copies of the DNA molecule artificially in a short period of time.

The PCR technique employs a variety of enzymes and all the prerequisites which are required in the DNA replication in vivo conditions.

In the given question, if the genome of the mummy has to sequence then after the collection of samples from the bones, the DNA has to replicate through the process of PCR. The samples from the different bone structures can be compared and analysed and a complete genome sequence can be analysed.

Thus, PCR is correct.
