Answer:
Answer is D.Produce non-identical genetically different gametes and reduction of chromosomes,creating a haploid gamete.
Explanation:
Meiosis is essential for sexual reproduction.In humans diploid gamete-mother cells or germ line undergo meiosis to produce haploid gametes.
The chromosomes pairs of each parent undergo crossing over during meiosis.so daughter cells i.e gametes have genetic variations.When gametes fuse and form zygote ,its genetic make up is different from both parents.thus meiosis allows a species to bring variations in next generations.Benenficial variations help organisms to adapt to the changes in environment.
Answer:
Evolutionary responses. In this case, interconnected with the <em>climate change </em>phenomenon.
Explanation:
Today, Climate change is considered one of the biggest challenges all species, including humans, have ever faced in the history of the Earth.
Many species are forced to adapt to these climatic variations by exhibiting different behaviors, changes in physiology, even in physical characteristics. <u>While some species will be able to adapt due to their plasticity, i.e. their ability to accommodate to these changes; others will not be able to adapt as fast as needed.</u>
In this case, some bird species with low plasticity will be facing population declines due to their inability to adapt quickly, while others will be able to survive because they are able to adjust their behaviors and physiology. <u>Both cases are examples of evolutionary responses, which in this case, are related to climate change.</u>
Answer:
C. Endocrine System
Explanation:
Simply put, the endocrine system is a network of glands that secrete chemicals called hormones to help your body function properly. Hormones are chemical signals that coordinate a range of bodily functions. The endocrine system works to regulate certain internal processes.
Theres only one that is commonly used and its methane
The correct answer is buildup of toxins.
One of the essential action of the liver is to process various kinds of toxins and to eliminate it out of the system of the organism. Although it is known as a toxin processor, it is not resistant to the toxins itself. As the liver is the main site for drug decontamination and stimulation, thus, the improper functioning of the liver may lead to the accumulation of toxins.
