Given,
H = brown hair
h = red hair
Mother: Hh (heterozygous It’s given)
Father: hh (homozygous, given)
What is homogeneous and heterogeneous?Homozygous means alike allele whereas heterozygous means unalike or distinct from one another.
So, in the punnet square below, it is shown that there is a 50/50 chance for the offspring to have red hair.
Ratio is 1:1.
But there is also another probability for the offspring to be like their mother, have the dominant gene of black hair overruling the recessive gene of red hair.

Which two natural resources will be most affected as people try to meet the growing demand for food?
Answers
Answer:
water and land
Explanation:
I assume this is an open-ended question, so you could make an argument for lots of things, but these are the two most important ones in my opinion. The amount of freshwater on Earth is pretty small, only about 2.5%, and most of that is locked in ice. As the demand for food grows, the demand for water for crops and livestock also grows. This is in addition to the increase in water that is needed for a growing population. Climate change increases this problem because of drought. The second most important resource that will be affected is land. If we need more food, we also need space to grow crops and raise livestock. The available space is also reduced because people need places to live and we need to be able to grow trees for wood to build houses and other buildings. I argue that land and water will be the most in-demand commodities as the population continues to increase.

discuss briefly on the origin of life according to creationists and naturalists
Answers
Answer:
Creationists believe that a god created everything in the universe, including all life. Typically they don't believe in evolution; they believe that their deity created every species exactly how it's supposed to be and they don't need to change. They believe that everything in nature happens for a planned reason.
Naturalists believe that everything in the universe happens by chance. They believe in theories like the Big Bang Theory, which states that the universe itself was created by chance. They also believe in evolution - that every species adapts to its surroundings and evolves more desirable traits. Naturalists believe that the first life happened due to the correct conditions coming together by chance to create unicellular organisms, which eventually reproduced, mutated, and evolved into the millions of specialized species that exist on earth now.

According to the research, the oceans and the forests perform a similar function in the carbon cycle that is taking carbon dioxide out of the atmosphere.
What is the carbon cycle?It is the biogeochemical process in which carbon circulates through the atmosphere, the oceans and the surface and interior of the Earth.
The oceans are considered the largest sinks of carbon, in its organic and inorganic forms, it is governed by physical and biological processes that act by increasing the concentrations of CO2 within the ocean.
Therefore, we can conclude that according to the research, the oceans and the forests perform a similar function in the carbon cycle that is taking carbon dioxide out of the atmosphere.

27. || The vocal tract. Many opera singers (and some pop singers) have BIO a range of about 2 \frac{1}{2} octaves or even greater. Suppose a soprano's range extends from A below middle C (frequency 220 Hz) up to E-flat above high C (frequency 1244 Hz ). Although the vocal tract is quite complicated, we can model it as a resoNting air column, like an organ pipe, that is open at the top and closed at the bottom. The column extends from the mouth down to the diaphragm in the chest cavity, and we can also assume that the lowest note is the fundamental. How long is this column of air if v=354 m/s ?

This is measures by open harmonics frequency.
f= n*V/(4*1)
What is frequency?
Frequency refers to the number of waves that pass a fixed point in unit time. Frequency is denoted by the symbol f, and is measured in hertz (Hz).
Given,
f=220
velocity= 354 m/s
=> 220 = (nl)*(354)/(4*1)
=>1244 = (n2)*(354)/(4*1)
=> n2/n1= 5.65
=> n1=1, n2=6
=> = 40 cm (final answer).
