Name three invasive species and the specific location on Earth that they are affecting.
yan [13]

Answer:

Rats - Virgin Island

Hemlock - Asia

Zebra moulds - Great Lakes

Explanation:

An alien species is one that was introduced into a new environment, but does not have harmful effects. Such alien species are considered invasive species as they begin to have harmful effects on the new habitat. Invasive species can cause damage to the ecosystem, economic harm or human health effects.

Three invasive species are as following:

  1. Rats that came on board ships to the Virgin Islands infested the islands' sugar cane fields and caused significant crop damage.
  2. The woolly adelgid hemlock is an invasive Asian insect which rapidly kills infested hemlock trees.
  3. Zebra moulds in the Great Lakes can easily cover submerged surfaces, obstructing water intakes at water treatment plants and power plants

Quincy has type B blood.
Irina-Kira [14]

Answer:

IBi and IBIB

Explanation:

Blood group in humans is determined by a single gene with three alleles (iA, iB and i). Alleles iA and iB are both dominant over i. This means that i allele will only be expressed in a homozygous state.

In the ABO blood group system, individuals will possess the following blood types when they possess the following genotypes:

Type A- iAiA or iAi

Type B- iBiB or iBi

Type O- ii

Alleles iA and iB are codominant, this means that they both phenotypically express themselves when combined as neither is dominant or recessive to the other. Hence, in an heterozygous state;

iAiB, the blood type of the individual will be Type AB.

Following this, Quincy with a type B blood will possess an allelic combination of iBiB (homozygous) or iBi (heterozygous) in her genotype.

What is the reason behind the high surface tension of water?
zhuklara [117]
Water is a very polar molecule.

This means there is a (slight) difference in charge between the ends of the water molecule. Water is made up of an Oxygen and two Hydrogens (H₂O). The Oxygen is a much larger atom, with 8 protons in its nucleus, whereas Hydrogen has only 1 proton.

As protons are positively charged, the oxygen has a greater positive charged, so the electrons which are negatively charged are more attracted to the Oxygen, and the bond shifts slightly towards the oxygen. As the electrons have shifted position, the negative charge has shifted position, to there is a slight negative charge nearer the Oxygen, δ⁻ (delta minus), and a slight positive charge, δ⁺ (delta plus), at the Hydrogen.

This allows strong inter molecular forces to occur, as the slightly positive Hydrogens are attracted to the slightly negative Oxygens. This force of attraction between water molecules causes them to want to 'stick together', causing a high surface tension.

So the answer is B)
