Answer:
The correct answer is C. does not have hemophilia
Explanation:
In the given pedigree John has an XH chromosome, which means that he has the dominant chromosome. As males have one X, they can either be affected or unaffected. So, in this case John could not be carrier. Also, the Dominant chromosome is fully functional and does not show the characters of the disease, so, John would be free of hemophilia.
Answer:
10000 units in the second
100000 units in the third
1000000 units in the fourth
Explanation:
According to the pyramid of energy, which describes how energy flows from one trophic level to another, only about 10% of the available energy is transferred to the organism in the next trophic level as a lot of energy (about 90%) is lost as heat.
In this question, in order to have 1000inits of energy in
- Second trophic level = 1000 = 10/100 × x
10x = 100000
x = 10000units of energy
- for third trophic level,
100 × 1000
= 100000 units of energy
- for fourth trophic level;
1000 × 1000
= 1,000,000 units of energy.
Science is an attempt to explain natural phenomena. People from all cultures contribute to science. Scientific knowledge relies heavily, but not entirely on observation, experimental evidence, rational arguments and scepticism
The statement which correctly describes natural selection is (1) it favors the survival of certain members of the species and results in a change in the proportion of individuals with highly <span>adaptive traits.
Natural selection, by definition talks about the successful passing down of genes from older generations to younger generations. These then are better adapted to their environment. This is exactly what the first answer is about. </span>
Answer: Biodiversity is important in supporting vital ecosystem services (ES) such as provision of clean water, but can also provide social benefits, such as improved employment. The report focussed on the impact of biodiversity on employment and the value of biodiversity and the services provided for vulnerable rural people.
