Select all that apply. Choose the cells that are diploid. egg nerve bone sperm muscle
Natali5045456 [20]
The diploid cells in this case include nerve cell, bone cell and muscle cell. A diploid cell is a cell that contains two sets of chromosomes, which is double the haploid chromosome number. They include all the somatic cells with exception of germ line cells. Gametes are haploid cells meaning they only have one set of chromosomes. During sexual reproduction, gametes (sperm and egg cells) fuse at fertilization to form a diploid zygote which develops into a diploid organism.

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

Compare the process of carbon fixation in C3 plants to that of C4 plants.
Gre4nikov [31]

Carbon fixation is the process in which plants remove the carbon from atmospheric carbon dioxide and turn it into organic molecules like carbohydrates.

Because different type of plants are located in regions with different conditions they are different types of carbon fixation.  Plants that live in arid regions need to conserve water, while plants that live in more moist conditions will not need to conserve water.

The carbon fixation in C3 plants is one-step process. An oxidation reaction occurs because of the enzyme RuBisCo.  During the oxidation some of the energy used in photosynthesis is lost in a process known as photorespiration.

What are the similarities in the way a barchan forms and the way a hooked spit forms?
choli [55]

Answer:

The similarities in the way barchan and hooked spit forms are:

First, they are formed from sediment or sand movement.

Second, this movement makes them have a peculiar curved form that provides them their major characteristic.

Explanation:

First of all, barchans are sand formations that are created after the accumulation of sand in a place is moved by the wind and provides them a curved form. However, they exist only out of the sea.

Second, hooked spits are formations that happen after sea movement displaces the sediment to create a curved structure that can only exist in the sea. These formations affect the strength and direction of the waves in the sea due to their curved form.
