A pink flowered plant is crossed with a white flowered plant. Show the punnet square. What is the probability of producing a pin

k flowered plant?

Biology

avanturin [10]3 years ago
7 0

Answer:

There is a 50% probability of producing pink flowers.

Explanation:

A dominant trait can be described as a trait that masks the effect of a recessive trait. A recessive trait can be described as a trait that is suppressed by a dominant trait.

Homozygous means that both alleles of a gene are similar whereas heterozygous means that the alleles of a gene are different.

Let's consider pink to be a dominant trait and white to be a recessive trait. Consider the pink flower to be heterozygous (RR') and the white flower to be recessive and hence homozygous (R'R'). When these plants are cross-bred, there will be a 50% chance that the offsprings will be white coloured and 50% chance that the offsprings will be heterozygous and will have pink colour.

Receptors trigger one of two effector pathways resulting in changes in neuronal activity. These changes will, ultimately, effect
kolezko [41]

Complete question:

Receptors trigger one of two effector pathways resulting in changes in neuronal activity. These changes will, ultimately, effect gene expression. Which effector pathway is characterized by ion flux through transmitter-activated channels resulting in an altered membrane potential and neuronal activity?

A.  Slow effector pathways

B.  Modulated effector pathways

C.  Rapid effector pathways

D.  NMDA glutamate receptor pathways

Answer:

D.  NMDA glutamate receptor pathways

Explanation:

The NMDA glutamatergic receptor is a cationic channel receptor modulated by a ligand that allows the transport of Na+, K+, and Ca2+. Under certain situations, it exhibits particular permeability to Ca2+. The receptor has different regions that are susceptible to modulation by endogenous and exogenous agents. The receptor can be found at most excitatory synapses, where it responds to the neurotransmitter glutamate. During synapsis, the presynaptic membrane releases L-glutamate, which is received by NMDA glutamatergic receptor. The receptor plays a regulatory role because activates signaling cascades that depend on calcium.

These receptors are involved in normal synaptic transmission, in a diverse physiological phenomenon, and might be responsible for neurodegenerative processes.

How does an increase in the use of coal affect biodiversity and air and water quality in a region?​
egoroff_w [7]

Answer:

by developing more efficient methods of mining coal  

Explanation:

Coal is a combustible black or brownish black sedimentary rock. Coal is produced by the dead plant matter. It is a fossil fuel that is used for generating electricity in the thermal power plants, used as cooking fuel, and fuel in automobiles. The burning of the coal results in the liberation of carbon dioxide, sulphur dioxide and carbon monoxide gases in the environment. These gases are responsible for causing the air pollution.

Developing more efficient methods of mining coal is not a conservation tactic related to coal consumption because the more the efficient mining will promote the excavation of the coal, which will further contribute to its extensive consumption and air pollution.

If bird song promotes an individual's ability to attract a mate and reproduce, then the song has a(n) _____ function. assumptive
Contact [7]

Answer:

If bird song promotes an individual's ability to attract a mate and reproduce, then the song has an <u>     function</u>

<u />

Explanation:

Within a community, certain novel traits are fixed because they impart beneficial adaptations on an individual in their ecosystem (like mate attraction). Such modifications enable such individuals to live longer than their peers, and breed over time to produce more offspring who also exhibit these traits.

Natural selection takes place and is determined by the fitness of an individual , it contributes to evolutionary change as individuals with certain traits reproduce, the traits become fixed and prevalent within the population.
