Answer:
This is called a heterozygous gene. So the answer should be true

Answer:
they have a nucleoid.
Explanation:
Unlike eukaryotes, they do not have a separated nucleus or organelles bound inside a membrane, so they have to keep their DNA and other genetic materials within a nucleoid.
Worldwide, there are 107 boy babies born for every 100 girl babies. This skewed ratio is partly due to sex-selective abortion and "gendercide," the killing of female infants, in countries such as China and India where males are more desired. But even discounting those factors, the completely natural male-to-female sex ratio still hovers around 105:100, meaning that women are inherently more likely to give birth to boys. Why?
Several factors influence whether a sperm containing a Y sex chromosome or one containing an X chromosome will be first to fertilize an egg, including parental ages, their environmental exposure, stress, the stage in the mother's ovulation cycle and even whether she has had children previously; all these forces combine to set the average sex ratio at fertilization at 105:100.
Answer:
abundance and occurrence are linearly related
Explanation:
The core-satellite hypothesis states that several species will be widespread and several species will be scarce. This is based on the assumption or prediction that species habitation is distributed bimodally.
Hence, according to the core-satellite hypothesis, it is believed that "abundance and occurrence are linearly related."
As there is an increase in the level or number of species, the chance of occurrence or seeing their species increases.
