- controls the transfers of materials in and out of the cell
- embedded with proteins
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.
<span>B.The products are H2O (water) and CO2 (carbon dioxide), which then undergo anaerobic respiration.</span>
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.

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.
