Answer:
The correct answer is option B. "needs, wants".
Explanation:
Needs are basic human requirements, which include the basics needs of food, shelter and clothing. On the other hand, wants are the ways in which needs are satisfied. For instance, the need of food is satisfied by the wants of different types of food, depending on cultural and socioeconomic factors.
Te answer is False. T<span>ension and relaxation are mutually exclusive--it is not possible to be relaxed and tense at the same time. R</span>elaxation of the body through decreased muscle tensions will, in turn, decrease mental tension. It is <span>Edmund Jacobson's who showed us Progressive Relaxation Technique.</span>
The correct answer is all of these.
Matter and energy on Earth are never destroyed or created out of nothing, but just transferred or converted to another form.
The inorganic matter is transferred to the living things from the physical environment by many biological processes like photosynthesis ( CO2), nitrogen fixation, absorption of the minerals by plant roots and many more.
Matter can then be transferred between different organisms through the food chain.
Eventually, the matter will return to the physical environment when organisms decompose and the cycle will start again.
Answer:
Changes in gene expression
Explanation:
This phenomenon is the result of changes in gene expression. That means, how the information in the DNA is used by the cell. The genes that are active in the cells of the brain will be very different from the genes that are active in the cells of the bone marrow.
These patterns of gene expression are different for each cell, and dictate the identity of that cell. Gene expression patterns are controlled by a variety of factors in the cell that allow tissue-specific expression, such a transcription factors.
This can also be facilitated by another layer of regulation called epigenetics, which literally means "on top of" genetics, and refers to modifications of DNA (and the proteins around it), that can reflect and influence the activity of the genes within.
Answer:
B) how changes in development underpin the evolution of morphology.
Explanation:
Evolutionary developmental biology is the new field of research in biology which studies the combined relationship of the evolution and the developmental processes.
This interdisciplinary study compares the developmental biology in terms of evolution or in a way that how the developmental biology process evolved in the organism on the basis of studying the phenotypic features of the organisms.
Thus, Option-B is the correct answer.
