Answer:
frequency of homozygous recessive = q² = 0.16
the predicted frequency of heterozygotes = 2pq = 2 × 0.4 × 0.6 = 0.48
the predicted frequency of homozygous dominant = p² = 0.6² = 0.36
Explanation:
Given that:
Number of recessive homozygous survivors = 16
Total number of population survivors = 100
Predicted frequency of homozygous recessive individuals (q²) = 16/100 = 0.16
Frequency of recessive allele (q) = √0.16 = 0.4
p + q = 1
∴ p = 1 - q = 1 - 0.4 = 0.6
Frequency of dominant allele (p) = 0.6
frequency of homozygous recessive = q² = 0.16
the predicted frequency of heterozygotes = 2pq = 2 × 0.4 × 0.6 = 0.48
the predicted frequency of homozygous dominant = p² = 0.6² = 0.36
p² + q² + 2pq = 1
0.16 + 0.36 + 0.48 = 1 (proved)
The reduction in population due to some event in the original gene is no longer in the surviving population. Since the population is now small, there is likely to be genetic drift.
The flash flood caused change in allele frequency leading to a micro evolution.
The correct answer is: right ventricle
There are two types of blood circulation:
1. Pulmonary circuit or circulation is a system of blood vessels between the heart and the lungs. In pulmonary circulation, deoxygenated blood leaves from the heart’s right ventricle through the pulmonary artery to the lungs. Oxygenated blood from the lungs (CO2 is released and O2 is picked up during respiration) is transported through the pulmonary vein and returned to the left atrium of the heart.
2. System circulation than transports oxygenated blood from the heart’s left ventricle through the aorta and to the rest of the body. Oxygen-poor blood from all tissues is then returned through the veins back to heart.
Answer:
Taking into account photosynthesis, the evidence that best supports the law of energy conservation is energy is absorbed by chlorophyll and becomes chemical energy during photosynthesis (option 2).
Explanation:
Plants are autotrophic organisms, characterized by synthesizing their own nutrients by converting solar energy into chemical energy through photosynthesis.
During the process of photosynthesis, chloroplasts are capable of absorbing solar energy and converting it into glucose. This process involves the conversion of one type of energy into another.
With respect to the law of conservation of energy, it is necessary to consider:
- In the universe there is a constant amount of matter and energy, which is neither created nor destroyed, but transformed.
- Energy in an isolated system does not vary, unless it comes into contact with another system.
- The amount of energy that is absorbed and obtained is equivalent.
In photosynthesis, the chloroplast is not an isolated system, but has contact with the outside and is capable of absorbing the energy of the sun. This energy will be used to obtain a product, glucose, in an amount proportional to the amount of energy absorbed.
Regarding other options:
<em> 1. In photosynthesis, it is not </em><u><em>mechanical energy</em></u><em> that is transformed into chemical energy.</em>
<em> 3. </em><u><em>Oxygen is a product of photosynthesis</em></u><em>, during the process of chemical energy synthesis, from the combination of carbon dioxide, water and solar energy.</em>
<em> 4. It is true that the </em><u><em>sun gives off light energy that is absorbed by plants</em></u><em>, but it does not explain how this energy is transformed into chemical energy.</em>
Your answer is B. hope this helps
