Why does frozen water take on the pattern it does (hint: it has to do with water’s polarity)?

damaskus [11]

When ice forms, one water molecule's hydrogen atoms form weak hydrogen bonds with the tops of the oxygen atoms of two other water molecules. Lining up the water molecules in this pattern takes up more space than randomly arranging them.

<h3>What is polarity?</h3>

A physical property of compounds that connects other physical properties like melting and boiling points, solubility, and intermolecular interactions between molecules is referred to as polarity.

When ice forms, one water molecule's hydrogen atoms form weak hydrogen bonds with the tops of the oxygen atoms of two other water molecules.

Lining up the water molecules in this pattern takes up more space than randomly arranging them.

When water freezes, the water molecules slow down enough that their attractions arrange them into fixed positions. Water molecules freeze in a hexagonal pattern, with molecules further apart than when the water was liquid.

Thus, because of this frozen water take on the pattern it does.

To check whether Earnest and Denise could have a baby with Type O blood, draw a Punnett square for a father who has blood Type A

Nutka1998 [239]

Answer:

Answer is explained below and also see the document attached below for Punnett square.

Explanation:

ABO blood type (A, B, AB, or O) is based on the presence (or absence) of the A and B antigens in the red blood cells. The blood type, A has only the A antigen (and has anti-B antibodies) while the blood type, B has only the B antigen (and had anti-A antibodies). Also in the AB blood type, both A and B antigens are present (but has no antibodies) while in the O blood type, both A and B antigens are absent (but has both antibodies).

The blood type is inherited from the parents and the offspring inherits one of the two alleles from each parent. The ABO blood type has three types of alleles: IA, IB, and i. Here, I is a term for antigen (isoagglutinogen).

The IA and IB alleles are dominant while the i allele is recessive. The blood type A is formed by either two IA alleles (IA IA ) or IA i. So, the genotype of blood type A is IA IA or IA i. The blood type B is formed by either two IB alleles (IB IB ) or IB i. So, the genotype of blood type B is IB IB or IB i. The O blood type is formed only by two i alleles (ii). So, the genotype of blood type O is ii. The IA and IB alleles (IA IB) give the AB blood type, which is an example of codominance (the traits of both the alleles are visible in the phenotype). The genotype of blood type AB is IA IB.

If the parents have blood type A and B, then they can have an AB blood type offspring. If the parents have blood type A and B and they both are heterozygous (IB i and IA i), then they can also have a O blood type child.

Here, the father has blood Type A (IA i genotype) while the mother has blood Type B (IB i genotype). Both the parents are heterozygous (IB i and IAi), so the possible genotypes of their child are IA IB (blood type AB), IA i (blood type A), IB i (blood type B) and ii (blood type O).

i.e., <u> Blood Type </u> <u>Genotype </u>

A IA IA or IA i

B IB IB or IB i

AB IA IB

O ii

The plasma membrane represents an energetic barrier to the free diffusion of ions from the extracellular space into the cytoplas

Marysya12 [62]

Answer:

Why are molecules such as valinomycin effective at transporting ions across the membrane?

Valinomycin is effective as transporting ions across the membrane because it is no charged, so it can carry ions.

Why would a drop in temperature to or below the transition temperature limit valinomycin mediated K+ transport across the plasma membrane?

Valinomycin is limited by temperature because its activity is highly sensitive and it depends on a stable and an average temperature.

Explanation:

Valinomycin is effective at transporting ion across the membrane because is an antibiotic that alternates hydroxy and amino acid, ans it helps membranes to be permeable. Valinomycin is a cyclic molecule that helps in ions transportation through membranes. Also, antibiotics have a temperature range of activity, that's why it is sensitive to changes.
