Explanation:
The results are explained if the trait blue eyes is dominant (B) over non-blue (b) and the dominant allele B is lethal in homozygous individuals.
<u>The possible genotypes and phenotypes are:</u>
- Homozygous dominant (BB): lethal
- Heterozygous (Bb): blue eyes
- Homozygous recessive (bb): non-blue eyes
When blue (Bb) is crossed with non-blue (bb) the resulting offspring is 1/2 blue (Bb) and 1/2 non-blue (bb).
When non-blues interbreed (bb X bb) all progeny is non-blue (bb).
Answer: Possible life in non earthlike environments.
Explanation: As per the information provided in the question, the microbe located in California's Lake Mono has a variation in the shape of its DNA as they use arsenic ( if phosphorous was once no longer available) to comprise in the nucleotides of their DNA.
This shows the possibility of life structure in the non-earth-like environment because existence types that originated on earth like environment possess carbon, nitrogen, oxygen, and phosphorous ( that is composed of four fundamental elements).
But existence can additionally be shaped in an environment that lacks phosphorous ( for instance, DNA shaped in microbes utilized arsenic in absence of phosphorous, indicating version in their structure).
Although it has recently been shown that certain bacteria are capable of dramatically changing shape, pleomorphy remains a controversial concept. A well accepted example of pleomorphism is Helicobacter pylori, which exists as both a helix-shaped form (classified as a curved rod) and a coccoid form.
Phagocytosis is to eating as pinocytosis is to drinking.
Answer:
Option D is a correct answer
Explanation:
An adaptation is adapted to suit the environment as every environment is different.
Different environment aids to different kind of adaptations that perfectly suits the animals living there.
The adaptation of an animal living in the desert region will have adaption to work in hot climate. The plant that grows in a desert area have no leaves and broad stem to store water.
The animals that live in the polar regions have thick fur to provide insulation and heat to live in polar region.
