Hello there,

The reason Enzymes are considered a catalyst is because Enzymes catalyze biochemical reactions.

Enzymes which are proteins that control the speed of Chemical reactions in your body. With out them, The chemical reactions would take place Very slowly to keep you alive.

Hope this helps

Enzymes are proteins functioning as catalysts that speed up reactions by lowering the activation energy. The definition of enzyme is that it is a biological catalyst. a catalyst is a chemical that increases the rate of a chemical reaction without itself being changed with the reaction.

Zarrin [17]

Answer:

Dessert and tundra

Explanation:

Theses two biomes get very little rain and because of this they have a less diversity of fauna and flora.

The differences are that a tundra is very dry and extremely cold and on the other hand a desert is very arid and hot and it can go as high as 54°C (130°F).

uranmaximum [27]

Streptococcus is a genus of coccus (spherical) Gram-positive bacteria belonging to the phylum Firmicutes[3] and the order Lactobacillales (lactic acid bacteria). Cell division in this genus occurs along a single axis in these bacteria, thus they grow in chains or pairs, hence the nameâ€”from Greekstreptos, meaning easily bent or twisted, like a chain (twisted chain). Contrast this with staphylococci, which divide along multiple axes and generate grape-like clusters of cells.)

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. It also specifies that these equilibrium frequencies can be represented as a simple function of the allelic frequencies at that locus. 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 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.

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

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.

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

In a paragraph discuss the process of the life cycle of seedless plants.

Alchen [17]

Answer:

The life cycle of seedless vascular plants alternates between a diploid sporophyte and a haploid gametophyte phase. Seedless vascular plants reproduce through unicellular, haploid spores instead of seeds; the lightweight spores allow for easy dispersion in the wind.
