A woman that is heterozygous for neurofibromatosis and a normal man (homozygous recessive for neurofibromatosis) will exhibit a 1:1 phenotype ratio in offspring (Option d).
<h3>What is a rare dominant autosomal genetic disease?</h3>
A rare dominant autosomal genetic disease is a condition inherited in a dominant pattern in very low frequency in the population.
Dominant autosomal genetic diseases are expressed in a 1:1 ratio because they are localized in autosomal (somatic) chromosomes instead of X and Y chromosomes.
In conclusion, a woman that is heterozygous for neurofibromatosis and a normal man (homozygous recessive for neurofibromatosis) will exhibit a 1:1 phenotype ratio in offspring (Option d).

Answer:
a. increasing birth rate with a greater number of young organisms
Explanation:
When the population growth is increasing in an area there is an increasing birth rate and the age structure begins to young.
Population growth is the increasing trend in population parameters that ensures that more organisms are produced.
The birth rate is the chief factor that populates an area.
When birth rate increases, new and younger organisms are produced and this tips the population towards a very young age.
An ageing population is one where the birth rate is quite low.
Answer:
<h2>The more the BMR then more the person becomes weak and lean. So, since sample A has more BMR this means that the person A is lean or thin as compared to person B.
</h2>
Explanation:
1. Basal metabolic rate (BMR ), At rest, the metabolic rate is known as the basal metabolic rate (BMR). And at rest, the BMR is low compared to when the body is undergoing activities like exercise
.
2. During this resting state the body needs to use energy only to keep vital organs such as the heart, lungs and brain working properly.
3. The metabolic rate can be measured in many different ways:
i) Oxygen consumption
, ii) Carbon dioxide production and iii) Heat production.
4. As a general rule for BMR, the greater the mass of an organism the higher that organism’s metabolic rate is. It is the amount of energy cell or organism spends at the resting stage. The more the BMR then more the person becomes weak and lean. So, since sample A has more BMR this means that the person A is lean or thin as compared to person B.
5. So, BMR is higher per unit of body mass in small animals compared to larger animals, because the higher metabolic rate of small animals needs a greater delivery of oxygen to tissues around the body.
Either feet or meters, but each country/state is different.
