Simora [160]
Answer:
A non-vascular plant is a plant without tubes to carry water and nutrients throughout the plant. Non-Vascular plants are less complex than vascular plants. ... Non-Vascular plants cannot grow very tall and because of their small sizes they can absorb enough water to carry materials throughout the plant.

4. Which event would be the most predictable one year in advance of the event?
Black_prince [1.1K]

Answer:

1. an eclipse of the Sun

2. state (phase) of matter

3. 5.0 g/cm3

Explanation:

1. Eclipse of the sun occurs when the planetary bodies align in such a way that causes the moon to block sunlight from reaching the Earth. The eclipse of the Sun will be the most predictable occurrence because it follows a pattern of occurrence. Eclipse of the sun occurs after a specific period of time, hence, based on this, scientists can predict that when it will occur next using its previous pattern of occurrence.

2. Considering the following groups: Group A: water, aluminum, water vapor

Group B: gasoline, ice, air

Group C: alcohol, iron, oxygen

One would realize that each constituent of each group exists in a particular state of matter. For example, in group B, gasoline is a liquid, ice is a solid while air is a gaseous mixture. Same applies for group A and C where water and alcohol are liquids, iron and aluminum are solids, while water vapor and oxygen are gases.

This shows that the STATE (PHASE) OF MATTER was the basis of classification.

8. Two rabbits are bred together. One is heterozygous for agouti coat
dusya [7]

Answer:

- Parental cross = Cch  x chch  

- F1 = 1/2 Cch (agouti coat); 1/2 chch (albino coat) >> 1:1 phenotypic ratio

Punnett  square:  

          ch         ch

C       Cch       Cch

ch    chch      chch

 

Explanation:

A heterozygous individual is an individual who has two different gene variants (i.e., alleles) at a particular <em>locus</em>. In this case, individuals having the "agouti coat" trait are heterozygous carrying both 'C' and 'ch' alleles. On the other hand, a homo-zygous individual has the same allele at a given <em>locus</em> (here, the 'chch' genotype associated with the albino phenotype). Therefore, as observed in the Punnett Square above, when a heterozygous parent is crossed with a homo-zygous recessive parent for a single gene, alleles segregate in the gametes of both parents so an expected 1:1 phenotypic ratio will be observed.

Given the names of these three enzymes proteases, DNase, RNase what reaction do you expect each one to catalyze
kramer

Answer:

As the name suggests, proteases will be the enzymes which will catalyze the reactions of proteolysis. Proteolysis can be described as the process of breaking proteins into amino acids and simple peptide bonds.

DNases will catalyze the reactions for breaking down or degrading DNA. The DNase does this by breaking the phosphodiester bonds present in the backbone of the DNA.

RNases will be the enzymes which will catalyze the breaking of RNA molecules.
