Answer:
The correct answer will be- phloem transports photsynthetic products to the roots
Explanation:
Phloem is the vascular tissue which specializes in transporting the solute molecules like sugar in the form of sucrose to in the plants.
The phloem connects the photosynthetic organ (Leaves) to non-photosynthetic organs (stem and roots) of the plants by transporting the photosynthates or sucrose to various parts.
Since the roots also need the energy to perform metabolic functions so need the photosynthates to synthesize the energy molecule. They receive the photosynthates from the phloem.
Thus, phloem transports photosynthetic products to the roots is the correct answer.
Potential energy or stored energy.
The right answer is B and C.
For proposal C, I will give you an example, that of an autosomal recessive disease. If a parent is heterozygous for an allele causing an autosomal recessive disease (due to a mutation), it may be that it transmits the allele to its descendence, as it may not be able to transmit it (since in one heterozygous subject, not all of its gametes carry the mutated allele) and thus the mutation will no longer be copied through the generaitons.
Each individual is genetically unique. Its genes are distributed along chromosomes contained in the nucleus. Mutations can lead to the appearance of different versions of genes: alleles. A diploid individual has two copies of each gene, which may be identical or different alleles. Mixing during sexual reproduction partly explains the genetic diversity of individuals.
Answer:
Examples:
- Short-term adaptation: feedback inhibition
- Long-term adaptation: regulation of gene expression
Explanation:
Feedback inhibition is a mechanism where the product of a chemical reaction is utilized to modulate its own subsequent synthesis. In bacteria, feedback inhibition allows regulating different metabolic pathways in response to environmental conditions by modulating enzyme activity through enzyme reaction products. Moreover, bacteria may also respond to environmental inputs by long-term changes in gene expression. For example, bacteria contain transcription factors activated during stress, which are able to activate the transcription of particular genes into messenger RNAs (mRNAs) that would subsequently be used to generate particular enzymes by the process of translation. These transcription factors may bind to specific DNA motifs in order to promote transcriptional activity, thereby regulating the production of the corresponding enzyme.
The correct answer is C. <span>a density-independent limiting factor
When bird populations sometimes decrease in areas due to wind farms, this occurrence is known as a density-independent limiting factor because it is not related so much to density.</span>
