nevsk [136]3 years ago

Answer: The size.

Explanation: On the one hand the Emperor Penguin is bigger reaching up to 48 Inches (120cm) of height and 100 Lb in weight, on the other hand the Galápagos Penguin is much smaller. For example a large adult usually goes up to 21 Inches (53cm) and 5 Lb of weight.

This is directly related to the temperature of the environment in which each one develops, because a body exchanges heat in two dimensions through the surface. So, it's easier for a big creature to maintain core temperature stable.

This is really important in environments like the Arctic where temperature goes below zero and the opposite happen in the Equator where there is a tropical weather all the time.

Why does ice become less dense than water?
myrzilka [38]
Ice actually has a very different structure than liquid water, in that the molecules align themselves in a regular lattice rather than more randomly as in the liquid form. It happens that the lattice arrangement allows water molecules to be more spread out than in a liquid, and, thus, ice is less dense than water.

Dimas [21]

Answer:

Organisms of all classes are matched as follows-

Explanation:

Insects-  Insects are a group in phylum arthropoda. They are having 6 legs and their body is devided into 3 parts- head thorax and abdomen.

Mollusca-  Second largest  phylum of invertebrates. These are mostly marine some live on land also. They have soft body with hard calcium carbonate shell known as mantle.

Bryophyta-  These are nonvascular plants. They dont have vascular system.They don't produce flowers or pollen. They reproduce by spores. Example- mosses

Aves- This is class of birds. Their charactersticks are beaks, toothless jaws,feathers and laying eggs.

Mammalia-  These are vertebrates animals class. They give birth to their young ones, female are  having well developed mammary glands to produce milk for young ones.  

Arachnida-  This is a class of invertebrates. It includes scorpion, spider. They are 8 legged creatures. Body has two parts.

Tongue rolling is a dominant trait. If two individuals homozygous dominant for this trait have a child, what is the chance that
Marizza181 [45]

Answer:

0

Explanation:

Let's assume that the gene coding for tongue rolling is encoded by letter T.

The allele for tongue rolling (T) is dominant over the allele for inability to roll the tongue (t).

In a cross between two homozygous dominant individuals (TT) i.e. they have the same dominant allele in their genotype and hence, they can both roll their tongues.

(See attached image)

The cross will produce four possible offsprings, in which all will possess a homozygous dominant genotype i.e. all will be phenotypically able to roll their tongues. Hence, in the case of the child, the child will be able to roll his tongue.

The probability or chance that the child will be unable to roll his tongue is 0. Since there is none.
