The dynamics of the ecological balance between the species might shift when invasive species are introduced to an environment.

<h3>What is invasive species?</h3>

An organism that harms the ecology or the economy in a new habitat where it is not native is referred to as an invasive species.

Both the ecosystem's natural resources and human usage of those resources may be harmed by invasive species. The ballast water of oceangoing ships, purposeful and unintentional releases of aquaculture species, aquarium specimens or bait, and other methods can all be used to introduce an invasive species to a new area.

Native plants and animals may go extinct as a result of invasive species, which can also decrease biodiversity, compete with native species for scarce resources, and disrupt habitats. Ecosystems along the coast and in the Great Lakes may be severely disrupted, with significant negative economic effects.

The introduction of invasive species to an ecosystem can change the dynamic of the ecological balance among the species.

<h3>What are invasive species?</h3>

Invasive species are those species that are capable of overtaking a new environment and harming the original population that lived in that particular affected environment.

It can cause harm to the residing population by affecting the number of species or reducing their bioavailability.

Does the net gain of atp in glycolysis differ when glycogen, rather than glucose, is the starting material? what is the change?.

salantis [7]

The energy is greater and producing a net gain of ATP in glycolysis of 3 ATP.

<h3>What is glycolysis?</h3>

The metabolic process known as glycolysis turns the sugar glucose (C6H12O6) into pyruvate (CH3COCO2H). The high-energy molecules adenosine triphosphate (ATP) and reduced nicotinamide adenine dinucleotide are created using the free energy released during this process (NADH).
A series of ten enzyme-catalyzed processes make up glycolysis. binding energy of carbs is captured. Retention of ATP One metabolic route that doesn't require oxygen is glycolysis (In anaerobic conditions pyruvate is converted to lactic acid)
Glycolysis occurs frequently in various species, which suggests that it is an old metabolic route. In fact, the events that make up glycolysis and its companion process, the pentose phosphate pathway, take place in the oxygen-free environment of the Archean oceans, also in the absence of enzymes, and are catalyzed by metal.

Jesse is studying a blood sample that has only antigen B on the red blood cells and antibody A and antibody Rh in the plasma. Wh

GarryVolchara [31]

Answer: the bloodtype of Jesse is A Rhesus D positive

Explanation:

Antigens at present on the blood cells while antibodies are present in the serum. Thus, to prevent agglutination which occurs if the red blood cell antigen is similar to the antibody, the red blood cell of Jesse which has the B antigen will have the A antibodies produced. Thus, since the red blood cell determines the bloodtype of a person, Jesse therefore has the B bloodtype.

How does genetic variation and environmental factors work together to cause natural selection?

Norma-Jean [14]

Because natural selection is caused so that an organism can adapt and better survive their environment. They are involved in the formation of fossils because organisms that die are buried in sediment and become fossils.

In humans, Rh-positive individuals have the Rh antigen on their red blood cells, while Rh-negative individuals do not. If the Rh

bixtya [17]

Answer: 60%

Explanation:

In population genetics, the Hardy-Weinberg Principle states that the genetic composition of a population remains in equilibrium as long as no natural selection or other factors are active and no mutations occur.

The frequencies of the genotypes of an individual locus will be set to a particular equilibrium value.<u> It also specifies that these equilibrium frequencies can be represented as a simple function of the allelic frequencies at that locus</u>. In the simplest case, with a locus with two alleles A and a, with allele frequencies of p and q respectively, the principle predicts that <u>the genotypic frequency for the dominant homozygous AA is p^2, that of the heterozygous Aa is 2pq and that of the recessive homozygous aa, is q^2. The allele frequency of a is represented as p and the frequency of recessive allele is q.</u>

The three genotypes AA : Aa : aa appear in a ratio p² : 2pq : q². If we add them up, we get the unit:

p^2 + 2pq + q^2 = (p + q)^2 = 1

And p + q = 1

<u>Rh-positive genotypes are represented as AA (homozygous dominant) or Aa (heterozygous) since the presence of a single dominant allele is sufficient to express the phenotype. While Rh-negative genotypes are represented as aa. </u>

If 84% of the population is Rh-positive, that means that this percentage includes all those who are AA and Aa. Then 16% are aa.

F(aa)=q^2=0.16

then F(a)=q=0.4

And since p + q = 1, p + 0.4 = 1, then p is 0.6

We can also calculate the rest, then F(AA)=p^2= 0.36

So F(Aa)= 2pq = 2 x 0.6 x 0.4 = 0.48

Notice that 0.36 + 0.16 + 0.48 = 1
