Once retinal has absorbed a photon which initiates effects that create nerve impulses, the impulses get carried to the brain, which then processes the impulses along with other signals, ultimately allowing the eyes to see.
Answer:
D) The fungicide will reduce the stability of the ecosystem because nutrients in the soil will be less likely to be recycled, directly impacting plant nutrition and growth.
Explanation:
Fungicide are primarily applied to an area to kill off fungi species in that place.
Fungi are very important groups of organisms. They are natural "recyclers".
In a food chain or web they can be classified as decomposers.
Decomposers are organisms that takes feeds on dead and decaying organic matter.
The produce useful materials and releases nutrients from life back into nature.
Killing them off by applying fungicides is a damaging act to their sustenance.
Without decomposers such as fungi, the ecosystem becomes less stable and soil nutrients will not be properly recycled.
The wrinkled pea will have two recessive alleles on the locus.
Explanation:
Two forms of same gene are called alleles of that gene.
The allele that expresses itself under heterozygous condition is called the Dominant allele.
The recessive allele can express itself only if they are under homozygous combination i.e. both the alleles on homologous chromosome are recessive.
Here wrinkled pea is a recessive trait and if it is expressed in the phenotype then the genotype of the plant must be homozygous for the recessive allele.
Answer:
2. G green (female) x white (male)
Explanation:
<em>The cross that could produce progeny plants with green leaves would be the cross between a green female and a white male.</em>
<u>Since the transmission of leaf color in the plant demonstrates organelle inheritance, the female controls which leaf color is inherited by the progeny. Organelles are generally located in the cytoplasm which is largely contributed by the female egg during fertilization. Hence, organelle inheritance are controlled by the female and that is why they are often referred to as maternal inheritance.</u>
Therefore, a cross involving a green female and a white male would largely yield green progeny provided that the trait inheritance follows an organelle inheritance.
