Answer: Climate change

Explanation:

Penguin are flightless birds which are found in the cold regions of the earth like Antarctica. They are adapted to survive in the cold environmental conditions.

In humans, to fold the tongue is a dominant trait (L), and the straight tongue is the recessive trait. What are the probabilitie
kaheart [24]

The given question is incomplete as the genotype of the parents is not given, so the answer is providing in the followings case:

1. dominant parent and recessive parent

2. heterozygous parents

Answer:

1. dominant parent and recessive parent:

dominant parents can be represented by LL and recessive parent is represented by ll, so the gametes would be L, L and l, l.

so,

 L    L

l  Ll   Ll

l  Ll   Ll

so there are all offspring in heterozygous condition as we known one or two dominant allele masks the recessive allele for the trait so 100% offspring can fold their tongue.

2. heterozygous parents

In this case, parents have Ll genotype and gametes would be L and l for each parent so,

    L    l

L   LL  Ll

l    Ll    ll

In this case, one is pure dominant and two heterozygous whereas only one is recessive so, the phenotype of offspring that cant fol the tongue would be:

3/4 = 75%

Where would contour farming and terraces be most likely to be found? a. On flat, expansive grasslands b. In wetlands c. On hilly
lara31 [8.8K]

Answer:

C. On hilly, mountainous farmland.

Explanation:

[] Terrace farming is where the slope is shifted to create a flat area for growing that also provides the ability to catch water.

[] Contour farming means that the fields suit the natural shape of the slope without changing it.

     Both of these farming methods most likely would be found where there are slopes and inclines, the only option providing us with this is "C" which gives us our answer.

Have a nice day!

An alpha particle can also be thought of as the nucleus of a helium atom and as such they are sometimes referred to as He2+ . The positive charge is due to the lack of two electrons.
