That's just the tip of the iceberg" is a popular expression you may have heard. It means that what you can see is only a small p
puteri [66]
Answer:

B 1.23 g/cc

Explanation:
For something to float on seawater, the density must be less than 1.03 g/mL. If the object sinks, the density is greater than 1.03 g/mL.

Let’s examine the answer choices. Keep in mind, the ice berg is mostly below the water level.

A. 0.88 g/cc
This is less than 1.03 g/cc, which would result in floating.

B. 1.23 g/cc
This is the best answer choice. The iceberg is mostly beneath the water, but some of it is exposed. The density is greater than 1.03 g/mL, but not so much greater that it would immediately sink.

C. 0.23 g/cc
This is less than 1.03 g/cc, which would produce floating.

D. 4.14 g/cc
This is much greater than 1.03 g/cc and the result would be sinking.

blsea [12.9K]
<h2>Answer 1:</h2>

Option D is correct: 0%

Percentage of offspring will be 0% white if a heterozygous male and homozygous dominant female have offspring.

<h2>Answer 2:</h2>

Option A is correct: 75%

Two parents who are heterozygous are expecting a child. the percentage that the child will have free ear lobes will be 75%.

<h2>Answer 3:</h2>

Option A is correct: 25%

Two parents who are heterozygous are expecting a child. 25 is the percentage that the child be homozygous dominant.

<h2>Answer 4:</h2>

Option D is correct: 25%

If a homozyous recessive and a heterozygous plant have offspring. 25 will percentage will have smooth seeds.

<h2>Answer 5:</h2>

Option D is correct: 0%

If a homozyous recessive and a heterozygous plant have offspring. There will 0% chances that offsprings will be homozygous dominant.

<h2>Answer 6:</h2>

Option D is correct: substitution

In this question one of base thymine at 7 number is substituted with another base Adenine.

<h2>Answer 7:</h2>

Option A is correct: Incomplete dominance

Incomplete dominance is a form of intermediate inheritance in which one allele for a specific trait is not completely expressed over its paired allele. This results in a third phenotype in which the expressed physical trait is a combination of the phenotypes of both alleles.

<h2>Answer 8:</h2>

Option A is correct: T T C G A A T C T G T A T G A C

After the insertion of a new base thymine the new sequence will be of option A.

<h2>Answer 9:</h2>

True

Yes this is true that "Environmental influences and genetics can determine a person's phenotype".

<h2>Answer 10:</h2>

Option B is correct: selective breeding

Humans have been choosing desired traits of livestock and pets for centuries by breeding organisms that they choose with the traits they desire. This process is called selective breeding.

<h2>Answer 11:</h2>

homologous chromosomes

karyotyping is a test that evaluates the number and structure of a person's chromosomes in order to detect abnormalities. Chromosomes are thread-like structures within each cell nucleus and contain the body's genetic blueprint.
