People who have Tay-Sachs disease cannot metabolize some lipids effectively. Tay-Sachs is a recessive disorder. A student used a
Yuliya22 [10]

Answer:

The parents must be Tt, Tt

Explanation:

Based on these results, we can conclude that each of the parents will have one dominant (T) and one recessive allele (t). We can prove this by drawing the Punnett square:

     T      t

T    TT   Tt

t     Tt     tt

We can see that the offspring will have the Tt genotype in two cases, the TT genotype in one case, and the tt genotype in one case, as well. Now we need to do some basic math. Two out of four is 50% (Tt - 50%), and one out of four is 25% (TT - 25%, tt - 25%).

This means that the parents must be Tt, Tt.

lukranit [14]

Answer:

Glucose

Explanation:

ATP, Carbon Dioxide, and Water are all results of Cellular Respiration and do <em>not</em><em> </em>form during Photosynthesis. These three are actually used in the process of Photosynthesis, so they are not created by it. Plants use photosynthesis to create their own glucose.

After differentiation, the various types of cells become specialized for a specific function. Their ______ relates to this _____
kykrilka [37]

Explanation:

The structure relates to their function

Their structural components (i.e. their makeup) determine their function (what they do). In specific cell types, collected proteins may function as a unit called an organelle.

Further Explanation:

In all eukaryotic cells mitochondria are small cellular organelles bound by double membranes make most of the chemical energy required for powering the biochemical reactions within the cell. this chemical energy is stored within the molecule ATP which is produced.

Some organelles are bound by membranes like those that make up the external structure of the cell, with varying compositions of phospholipids and proteins. These are advantageous, as they

  • may increase metabolic reaction efficiency;
  • they allow cells to concentrate smaller fractions of enzymes and solutes separate proteins and molecules that may harm the cells by parceling them into membrane-bound organelles
  • for example, hydrolytic enzymes concentrated within vacuoles may degrade macromolecules like DNA and RNA within the cytoplasm.
