The answer is B. because if the water has a lower boiling point when salt water get boiled the water boils first so it disappears when the salt has a higher boiling point

The correct answer is (b) The water has a lower boiling point than salt.

The separation of salt from water is carried out by the process of distillation. The boiling point of water is lower than that of salt so the water converts into steam on heating and the salt remains in the vessel. When salt is mixed in water, there occurs a phenomenon called elevation in boiling point of water but the change is very less as it cannot be observed. Even if there is a elevation in boiling point of the water it is lower as compared to the boiling point of salt.

In one type of plant, orange petals (O) are dominant over yellow petals (o) and tall stems (T) are dominant over short stems (t)
vodka [1.7K]

Answer No 1:

The set up of the punnet square is shown in the attached diagram. As the alleles assort independently hence the gametes formed will be OT,Ot,OT,Ot and OT,Ot,oT,ot. These will be the outcomes of the possible gametes formed. When these gametes are cross bred, the results are shown in the diagram attached.

Answer No 2:

The outcomes of each possible genotype are:

OOTT = 2/16

OOTt = 4/16

OOtt = 2/16

Oott = 2/16

OoTT = 2/16

OoTt = 4/16

Answer No 3:

The likelihood of each possible offspring phenotype is:

Orange petals with tall stem  and orange petals  with small stems present in ratio 12:4 i.e. 3:1.

What do deep roots do for the plant
aksik [14]

Answer:

Here you go :)

Explanation:

Plant roots complete a cycle in the soil. The deeper they go, the more benefits they provide to soil fertility and stable carbon storage in soils. While alive and active, roots redistribute carbon and nutrients throughout the soil profile.

Answer:

A

Explanation:

The reaction used in the brewing industry is realized by a fungus called Saccharomyces Cerevisae which converts glucose into ethanol and carbon dioxide. Glucose is first transformed into pyruvate.

The second reaction is the reaction for lactic fermentation made by bacteria like Streptococcus lactis or Lactobacillus bulgaricus

The third reaction is the reaction of aerobic respiration

Crawfish are shelled organisms that live in shallow freshwater rivers. They can have antennae of different lengths. Two parents
vredina [299]

The phenotype of antenna in crawfish depends on the protein amount in the antenna length. The offspring have different phenotype than their parent because of the amount of protein translated from each parent gene is determining in this.

The gene determines the amount of protein to be present in the antenna to determine its length.

Explanation:

Data given:

Two crawfish parent = medium length antennae, genotyoe Ll

One offspring = short antenna, genotype ll

one offspring = long antennae, genotype LL

The traits in offspring is shown as:

       L    l

L   LL    Ll

l   Ll     ll

The proportion of allele present in the gene determined the length of the antenna in crawfish.

The difference in length of the antenna in crawfish is due to the amount of protein for the phenotype present in the individual. The amount of protein to be expressed in the crawfish is given by both the parents. The tendency of protein expresed define the phenotype of antenna length.
