Water has several properties that make it unique amongst compounds and make it possible for all forms of known life to function.

The graph provided depicts what happens to the density of water as the temperature gets colder. According to the graph, what happens to the water’s density as it freezes and why? (SC.912. L.18.12)
When the temperature of the water finally goes below 4°C, the density of water decreases and as a result ice does not sink. The surface water freezes at 0°C while the lower part remains at 4°C

When the temperature of the water finally goes below 4°C, the density of water increases and as a result, ice doesn’t sink. The surface water freezes at 0°C and the water below freezes as well, allowing life to exist below frozen lakes

Water continues to get denser as the temperature get colder

The properties of cohesion and adhesion are directly responsible for water expansion at 4°C allowing aquatic life to survive under frozen lakes

Water’s density increases as it freezes or at lower temperature.

<h3>How cold water has more density?</h3>

Cool water has more density because cooling a substance leads to molecules to slow down and get closer to one another, occupying a smaller volume that results in an increase in density while on the other hand, the warm water is less denser and will float on room-temperature water.

So we can conclude that cold water is more dense and will sink in room-temperature water.

when two true breeding pea plants that show contrasting traits are crossed 1) mention the pod shape in F1 generation 2)work out
agasfer [191]

Answer:

1.) Inflated pod shapes (Cc) in the F1 generation

2) See attached image for the work out of the cross from P generation to F2 generation.

3). CC- 1/4, Cc- 1/2, cc- 1/4

Explanation:

This question is related to the pod shape trait encoded by a single gene in pea plants. The alleles for inflated pod shape (C) is dominant over the allele for constricted pod shape (c). This means that allele "C" will be expressed over allele "c" in a heterozygous state.

The two truebreeding parent plants will have genotypes: CC (inflated pod shape) and cc (constricted pod shape). When these two plants are crossed, an all heterozygous plant with genotype: Cc will be formed in the F1 generation. Since, C is dominant over c, the F1 Cc plants will have an inflated pod shape phenotype.

The F1 Cc plants are self-crossed to produce the F2 generation offsprings i.e. Cc × Cc. The gametes C and c will be produced by each F1 parent, which will be used to draw a punnet square (see attached image). From the cross, offsprings with genotypes: CC, Cc and cc are produced in the F2 generation.

CC (phenotypically inflated pod shape)- 1/4

Cc (phenotypically inflated pod shape)- 1/2 or 2/4

cc (phenotypically constricted pod shape)- 1/4

Why is the disposal of nuclear waste a greater problem than the disposal of the trash that you and you family need to get rid of
Vesna [10]

Answer:

nuclear waste has radiation, which is harmful to humans, so nuclear waste has to be stored in special facilities. Nuclear waste takes a lot longer than regular waste to decompose too.

This chemical is linked to the beginning of childbirth and is thought to signal the uterus to begin contractions:
ASHA 777 [7]
I believe the answer is Corticotrophin releasing hormone. Corticotropin-releasing hormone is a peptide hormone involved in the stress response. It is a releasing hormone that belongs to corticotropin-releasing factor family. Its main function is the stimulation of the pituitary synthesis of ACTH, as part of the HPA axis.  The Corticotropin releasing hormone derived from the placenta is secreted into the maternal circulation in large amounts during the third trimester of human pregnancy and may have an important role in the onset of labor.

Cousteau and Gagnan:
Leviafan [203]

Answer:

The answer is A. Invented SCUBA

Explanation:

  • Emile Gagnan and Jacques Cousteau were engineers who invented the first SCUBA device, the Aqua-Lung.
  • Gagnan's most important contribution to this discovery was his theory that a valve commonly used in gas generator engines would be useful in regulating air supply under water in varying pressures.

What are the body’s three defenses? How do they differ from each other.
Artemon [7]

Answer:

- Physical and chemical barriers

- non-specific innate responses

- specific adaptive responses

<u>The differences are...</u>

The first barrier is the physical and chemical barrier. It is the first line of defense when in contact with outside sources, this can be through the skin, earwax, nose-hair, etc.

The second barrier, the non-specific innate response, is after these outside sources have somehow managed to pass through the first barrier. They come into contact with cells and enzymes that help to defeat them.

The third barrier, the specific adaptive response, is the body's way of dealing with pathogens that the body has encountered before. (B cells activate)
