Answer:

B, C, E.

Explanation:

Unsaturated fats are more likely than saturated fats to be liquid at room temperature. (because saturated fats are solid at room temperature and unsaturated fats are liquid at room temperature).

Triacylglycerols (triglycerides) are composed of fatty acid residues and glycerol. (because by the reaction between glycerol and 3 long chain fatty acid triglycerides formation occurs and form 3 ester linkages).

Fats that contain more unsaturated fatty acid residues than saturated fatty acid residues are more likely to be liquid at room temperature. (because saturated fats are solid at room temperature and unsaturated fats are liquid at room temperature).

A man who is an achondroplastic dwarf with normal vision marries a color-blind woman of normal height. The man's father was six
Degger [83]

Answer:

1/4.

Explanation:

The autosomal dominant trait means that the trait is visible in homozygous dominant and in heterozygous condition. The X linked recessive trait will be pass down from mothers to their sons and daughters will show the trait in homozygous recessive condition only.

The man is achandroplastic dwarf ( Aa) with normal vision (XY ) is married with woman that has normal height (aa) with color blind (XhXh). They have a daughter who is dwarf ( Aa). The probability of being dwarf can be calculated by the cross Aa × aa. The offspring are Aa, Aa, aa, aa. Means 1/2 are the probability of being hetterozygous for achondroplastic . The vision probability is calculated by cross XY and XhXHh. The probability that female is heterozygous is 1/2.

So, the heterozygous probability for both trait is 1/2× 1/2 = 1/4.

What is the advantage of having a folded inner membrane in the mitochondria
Aliun [14]

Okay so, the mitochondria are shaped perfectly to maximize their productivity. They are made of two membranes. The outer membrane covers the organelle and contains it like a skin. The inner membrane folds over many times and creates layered structures called cristae. The fluid contained in the mitochondria is called the matrix. The folding of the inner membrane increases the surface area inside the organelle. Since many of the chemical reactions happen on the inner membrane, the increased surface area creates more space for reactions to occur.

Hope that helps (:

What is the difference between the life cycle of ferns and the life cycle of humans?
Bond [772]
Ferns make their own food. They grow and reproduce using spores instead of things like seeds. Humans on the other hand have to ingest food from their surrounding and when mature reproduce sexually. They can also choose if they want to reproduce or not while ferns don't have that option. Sexual reproduction is based on inseminating and egg cell, while ferns don't worry about this because the spores just fall on the ground.
