Using natural resources found in the environment, what did sumerians build strong walls with?

stiv31 [10]

Sumerians built walls using the natural resource they were surrounded with, which was namely clay. They used this clay to create fired mud-bricks, as there was not any other building stone available at the time. However, the clay mud-bricks proved to be a solid structure for town fortification.

What is the relationship between the number of motor neurons recruited and the number of skeletal muscle fibers innervated?

Alisiya [41]

Answer:

Alpha motor neurons (also called lower motor neurons) innervate skeletal muscle and cause the muscle contractions that generate movement. Motor neurons release the neurotransmitter acetylcholine at a synapse called the neuromuscular junction.

Achondroplasia is an autosomal dominant genetic disorder in humans. If a man with Achondroplasia ( heterozygous) and a normal wo

tresset_1 [31]

Answer and Explanation:

Achondroplasia is a form of dwarfism that affects the formation of cartilage; early in development, most of the skeleton is comprised of cartilage. Cartilage is a type of flexible, tough tissue; in achondroplasia ossification (conversion of cartilage to bone) is affected. Symptoms include an enlarged head, shorter upper and lower limbs, and limited motion at the elbow.

Punnett squares are illustrations that display the product of hybrid trait crosses by genetic breeding.

For this cross...

Assuming Achondroplasia= dominant

Parent generation or P generation:

gametes: An → Achondroplasia dominant (A), No Achondroplasia recessive (n)

Heterozygousity describes the allelic makeup; these traits comprise two varying forms of a gene. However, homozygous traits comprise identical forms of the gene.

Male: An → with Achondroplasia

Female: nn → without Achondroplasia

genotypes and phenotypes for parent and offspring...

Assuming heterozygousity of the male , for the cross

P generation: An × nn

Achondroplasia × No Achondroplasia

F1 generation:

genotype: An × nn ...(from punnet square)

phenotype: 2 with Achondroplasia ; 2 without

∴ 50% are genotypically heterozygous while 50% is homozygous , 2 with Achondroplasia ; 2 without

Why must males inherit colorblindness or hemophilia from their mothers?

sdas [7]

Men must inherit colorblindness or hemophilia from their mothers because colorblindness and hemophilia are located on the X chromosome, which are inherited from their mother.
