Answer:
<u><em>The benefits of genetic diversity include:</em></u>
- 2- species survive despite negative mutations
- 4- species adapt to ever-changing environments
- 5-gene pool is strengthened
Explanation:
Mutations resulting from errors within gene replication frequently accumulate within species, becoming more stable over time. They lead to other forms of the same genes called alleles.
Several alleles within a population's gene pools leads to higher diversity. These may become beneficial, as the environment of the organism changes.
Mutations that confer benefits tend to help organisms survive and produce offspring, passing on these genes. However, some mutations may be deleterious/harmful and fatal. High diversity reduces the deleterious effects of some mutations on a population for a stronger gene pool i.e. the species survives.
Blood vessels expand during hot weather and retract/ tighten in cold weather
Answer:
Explanation:
The color of our hair, skin, and eyes is determined by the same thing: the amount of pigment they have. The pigment that causes dark hair, skin, and eyes is called melanin. Melanin is made in special cells in the body called melanocytes.
The statements that describe steps taking place in the nitrogen cycle are
- Many biotic and abiotic factors play a role in recycling nitrogen ( A )
- Farming practices and chemicals lead to a build-up of nitrates in the soil ( E )
Nitrogen cycle is biochemical process whereby nitrogen is converted to various chemical forms as it passes through the atmosphere, Marine and terrestrial ecosystems .
Nitrogen cycle undergoes four ( 4 ) important processes which are :
- Fixation
- Ammonification
- Nitrification and
- Denitrification
Hence we can conclude that The statements that describe steps taking place in the nitrogen cycle are :
Many biotic and abiotic factors play a role in recycling nitrogen and
Farming practices and chemicals lead to a build-up of nitrates in the soil
