Biology
1 answer:
swat323 years ago
8 0

Answer: a) If the independent variable is changed, then the dependent variable will also change.

Explanation:

A hypothesis is the assumed explanation for the cause of the natural process. This can be testified on the basis of the experimental process, which will involve the cause and effect relationship between the independent and dependent variables.

The independent variable can be changed in an experiment manually. The impact of such change can be observed on the dependent variable to test the hypothesis.

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.

What is the complementary base sequence of the DNA strands of the template strand reads TTGCACG
Nadya [2.5K]

So there are four types of nucleotides in DNA:

  1. Adenine
  2. Cytosine
  3. Guanine
  4. Thymine

And the complements are:

  1. Adenine ⇄ Thymine
  2. Cytosine ⇄ Guanine

<u>Using this information, the complementary base of TTGCACG is AACGTGC.</u>

A small island is home to a unique population of land snails. This population was founded by 10 individuals that floated to the
vekshin1

Answer:

  • The Island population likely has fewer alleles-that is versions of genes-than the mainland population.

       A- Agree <u>B- Disagree</u>

  • Genetic drift is more pronounced in the island population than in the mainland population in these first few generations

       A- Agree <u>B- Disagree</u>

  • Some harmful traits may have become more common in the island population than in the mainland population

       <u>A- Agree</u>- B- Disagree

  • Biologist observed genetic drift but not evolution

       <u>A- Agree</u> B- Disagree

Explanation:

If there was genetic drift, then allele frequency either increased or decreased by chance, irrespective of natural selection that is irrespective to weather those alleles helped individuals survive in the island environment. In molecular genetic data, there are statistical signature in the  population variation that indicate weather selection or other processes occurred.
