2 covalent bonds

Explanation:

A molecule of water has two covalent bonds in it. Each attaching one oxygen to the central hydrogen atom.

          O ---  H  ----- O

  • A covalent bond is a bond type formed between non-metals.
  • It involves the sharing of electrons between two chemical species to attain stability.
  • Most times the electronegativity difference between the two atoms are usually low and close to zero.
  • The central hydrogen atom shares electrons with both oxygen.

An individual that is homozygous dominant for type B blood and little finger shape mates with an individual that is heterozygous
gregori [183]

Answer:

Let "L" be the dominant allele for little finger shape and "l" be the recessive allele for the same.

It is given that a person is homozygous dominant for blood group B and little finger shape. Hence, the genotype would be I^BI^B<em>LL</em>

The other person is heterozygous for blood group A and homozygous recessive for little finger shape. Hence, the genotype would be I^Aill

The type of gametes formed by the first parent would be I^BL<em> </em>only.

The type of gametes formed by second parent would be I^Al and <em>il.</em>

The cross is shown in the attached figure.

According to the cross, we get two phenotype:

  • offspring with blood group AB and dominant little finger shape, and
  • offspring with blood group group B and dominant little finger shape.
  • They are present in 4 : 4 = 1 : 1

According to the cross, we get two genotype:

  • I^AI^BLl
  • I^BiLl
  • They are also present in 4 : 4 = 1 : 1.

MAXImum [283]
<span>When a cell is "at rest" it is in a state called the resting potential.
In this state, neurons are more negatively charged ions inside the cell than outside the cell.
A resting neuron also known as non-signaling neuron. A neuron is made up cells.There are many types of cells in the body. The approximate value of cells is 37.2 billion in our body.</span>

Answer:

To make sure that the experiment is accurate, the scientist must make carry out an appropriate observation, which would lead to the formation of good hypothesis. Good experimental method is an other criteria to look forward for the accurate experimental results. Methods are applied in collection of data and other things and in compiling results using statistical methods to carry out an accurate experiment.
