Answer:
Muscle fatigue is a common complaint in clinical practice. In humans, muscle fatigue can be defined as exercise-induced decrease in the ability to produce force.
Explanation:
Spindle fibers form in cell divison
The correct answer is C. Gardeners choose which plants they let reproduced based on the plant traits.
Explanation:
In general, selective breeding involves the intervention of humans in the reproduction of species, this includes mainly plant and animal species. Moreover, in selective breeding, humans choose which specific species or individuals reproduce to favor certain traits. For example, a farmer might allow only the biggest cows to reproduce because this will lead to bigger calves. In this context, the option that shows selective breeding is C because this shows the intervention of humans in reproduction by selecting the individuals that will reproduce.
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 incentive the government offer to business who lower their carbon emission and use alternative energies include:
- Renewable Electricity Production Tax Credit (PTC)
- Investment Tax Credit (ITC).
<h3>What is Carbon emission?</h3>
This refers to the amount of carbon dioxide when fossil fuel such as coal, crude oil is burnt for different types of reasons.
This is required to be reduced as it is responsible for pollution and global warming being experienced in different parts of the world.
There are several types of incentives offered to businesses in other to encourage them to lower their carbon emission and adopt the use of alternative sources of energy and an example is Investment Tax Credit.
