Cancer cells are anaplastic in that they "form backward" to an earlier de-differentiated state. the cells have nuclei that vary

soldier1979 [14.2K]

The cells have nuclei that vary in size and shape, termed pleomorphism.

Pleomorphism is usually defined in biology as the occurrence of multiple structural forms during the life cycle of an organism. In anaplasia, it represents multiple structural forms of nuclei. Pleomorphism is a characteristic feature found in malignant neoplasms, and dysplasia, but it can also be found in certain benign cell types.

Epinephrine acts as a signal molecules that attaches to ____ proteins.

tia_tia [17]

Answer:

G-protein-linked receptor

Explanation:

Epinephrine acts via G-protein-linked receptors. The heterotrimeric G proteins located within the cell are activated by G protein-coupled receptors that span the cell membrane. Signaling molecules bind to a domain on the GPCR located outside the cell, and an intracellular GPCR domain then in turn activates a particular G protein.

what would be the most likely effect on cellular respiration if a plant were to lose much of its cjhlorophylkl

goldenfox [79]

Cellular respiration would produce less energy when plant were to lose much of its chlorophyll.

Plants can actually live longer without photosynthesis than they can without respiration. Some plants survive half the year without performing photosynthesis, but if they stop performing cellular respiration, even for a minute, they would be dead where they stand.

During photosynthesis, plants absorb sunlight and carbon dioxide from the air. Through a series of steps, much like cellular respiration, they convert these reactants into the products oxygen and glucose. The plants then can use the oxygen and glucose to make ATP in cellular respiration. The rate of respiration is greater than the rate of photosynthesis. So this means there is an overall excess of carbon dioxide is produced during respiration.

adell [148]

Yes, it is possible.

In this case both of the parental plants were heterozygotes and they manifested dominant allele in their phenotype, which is round seed.

P: Aa x Aa

F5: AA, Aa, aA, aa - possible genotypes in fifth generations.

A- dominant allele (round seeds); a- recessive allele (wrinkled seeds)

Wrinkled phenotype is manifested only if there are two recessive alleles present.

Basic body color for horses is influenced by several genes, one of which has several different alleles. Two of these alleles— th

Phantasy [73]

Answer:

<h2>No,</h2><h2>Phenotypic Ratio: 1 Chestnut : 2 Palomino : 1 Dilute</h2>

Explanation:

As given:

The chestnut (dark brown) allele and a diluting (pale cream) alleles show incomplete dominance, means that both the alleles in heterozygous condition show their effect. So the heterozygous show the phenotype which is intermediate of both the parents, here a horse heterozygous for these two alleles is a palomino.

There is in fact, no particular allele present for palomino, this phenotype only results due to having two different alleles for a gene. So, palominos can never be pure-breeding because they can never be homozygous.

Let P1 chestnut and P2 dilute,

Palomino is P1P2

The Punnett’s Square for palomino mated to palomino:

P1P2× P1P2

Gametes are: parent-1 P1 and P2 , parent-2: P 1 and P2

Progeny are: P1P1, P1P 2, P 2 P1, P2 P2

Genotypic Ratio: 1 P1P 1 : 2 P1P 2 : 1 P2P 2

Phenotypic Ratio: 1 Chestnut : 2 Palomino : 1 Dilute
