In human species, the allele responsible for myopia is dominant over
the allele responsible for normal vision.
A heterozygous myopic man marries a woman with normal vision.
1- Designate, by symbols, the corresponding alleles.
Answer:
'M' for dominant whereas 'm' for recessive allele.
Explanation:
Allele used for myopic man is 'M' whereas the allele used for normal vision is 'm'. The 'M' represents that the allele is dominant and the 'm' refers to the recessive allele. When the dominant allele combine with recessive allele, the organisms have physical features from the dominant organisms while on the other hand, the recessive allele hide and do not appear in the physical appearance of that organisms.

Which subatomic particle is positively charged?
A. Neutron
B. Ion
C. Proton
D. electron
Answer:
Proton
Explanation:
Neutron are neutral, ion I am not sure but are not positive, and electron are -.
Answer: Proton
Explanation:
In an atom there exist three types of sub atomic particles
1) Electrons
2) Neutrons
3) Protons
so we know that electrons are negatively charged particles which stays in a finite orbit as per their energy level
Protons are positively charged particles which remains inside the nucleus and they are tightly bound inside it
Neutrons are neutral sub atomic particles which do not have any charge in it.
So we have correct answer as
D) Proton

a vial with water,bromothymol blue,carbon dioxide , and a plant are left for 24 hours in the light. the color of the solution turns from yellow to blue . this color change is due to the plant
The dissolution of bromothymol blue into the solution can change the colour of the solution from yellow to blue.
Why the colour of the solution change?The color of the solution turns from yellow to blue color due to the release bromothymol blue because plant can't absorb bromothymol blue so it dissolved in the solution which leads to the change of colour of the solution from yellow to blue.
So we can conclude that the dissolution of bromothymol blue into the solution can change the colour of the solution from yellow to blue.

Answer:
Factors affects each landforms differently and shapes it depending on the nature of surface.
Explanation:
Water is one of the main erosion agents that help in shaping the lands. The mountains and hilly regions of world are all shaped by the wind and water an important geomorphic agent of change. Water flowing down from mountains has the ability to make various landforms such as V-shaped valleys, steep slopes ridges, and many geographical features. While in deserts water can lead to flash floods. Sheet erosion formation of canyons, gorge, channels, etc.Which renewable energy resource is the primary source of energy for life processes on Earth?

Based on the information in the model, you might predict that there is more nitrogen in the soil now than before the industrial production of fertilizer began
Answer:
The answer is "True".
Explanation:
Nitrogen, potassium, or sodium fertilizers are examples of direct fertilizers. If nitrogen is being used as a nitrogen source in such a fertilizer, another synthetic method necessitates the use of natural gas - water. Sulfur, carbon, and industrial minerals are being used to make the phosphate element, that's why the given statement is true.
