Answer:
after nutrients are absorbed during digestion,the excretory system removes faeces through the rectum. these work together to maintain oxygen homeostasis.
Answer:
C. Tap root system
Explanation:
The taproot is the primary root that is derived from the radicle directly. This primary root has many lateral roots originating from it. Root vegetables such as carrots are classified as tap roots.
These root vegetables are fleshy in nature. The taproot of carrot is modified to store the food. Storage of food makes the tap roots of these vegetable swollen in appearance. Another example of root vegetable is turnip which is also a taproot.
Answer:
1. genetics
2. constant
3. genetic drift
4. Modern synthesis combines the ideas surrounding evolution and natural selection with those of genetics.
5. A genotype is the genetic makeup of an organism. It describes the DNA that underlies a trait. There are dominant and recessive alleles and heterozygous and homozygous genotypes. A phenotype is the physical manifestation of that genotype.
6. The most common type of mutation is a deleterious mutation. Natural selection acts to remove this allele from the population.
7. The most common type of observed mutation is a neutral mutation. This mutation doesn't impact natural selection in any noticeable way since it doesn't impact the fit of that organism. Since neutral mutations convey no advantage, they generally must spread in a population through drift. Many also will disappear through drift.
8. During sexual reproduction, each organism is provided a copy of chromosomes from each parent, and this allows for new combinations of DNA.
9. This isn't an example of genetic drift because there's a genetic component to the ability to withstand severe temperatures. Therefore, this is an example of natural selection, related to surviving extreme environmental conditions
Explanation:
The answer is A.
As the population increases, so will deforestation. With deforestation, habitats will be destroyed leading to a decrease.
