If two Bb guinea pigs cross, there are four possible outcomes:
- both pass the B: the son is BB
- one of the pass the B and the other pass the b: the son is Bb
- both pass the b: the son is bb
Since B (being black) is dominant, the son will be black in both BB and Bb cases. In order for a son to be brown, he must be a pure bb specimen.
So, if all of the offspring are black, it means that all four guinea pigs are either BB or Bb, which in turn means that at least one of the parents passed the B gene.
Here's the fact:
"Altering the DNA of plants always reduces the nutritional content" is a FALSE statement. In fact, GMO products often have nutrients added.
"<span>Genetic modification reduces the genetic variation in both plants and animals" is a TRUE statement. The natural genetic variation that keeps species thriving is decreased when the plants are modified. Less diversity within a species puts it at an increased risk of being affected by disease or even becoming extinct. Genetic diversity causes resilience, since not every strain of a species will die off in the case of contracting a disease because they are all different. The more similar species are, the more they are at risk. However, so long as companies make variations of GMO foods, we should be fine.
"There have not been enough long-term studies to prove that this food is safe" is a TRUE statement. Some modern studies say genetically modified foods bad, some say they're good, some say they're neutral; however, since GMOs have only been a thing since 1994, there are no long term studies. Without long term studies, there is no way to confirm the safety of GMO foods.
"There have been many studies showing that these foods cause disease" is a FALSE statement. There have been many studies of GMO foods, but many haven't found any worthwhile data, except a few allergies.
Answer: There have not been enough long-term studies to prove that this food is safe.

Since the cell is hypotonic compared to the solution surrounding it which is hypertonic, the water will move out of the cell in an effort to reach equilibrium between the two.
I’m sorry I’m not sure about this question
Answer:
<u>I. Define the following terms:-</u>
Population ➝ the world population is the total number of humans currently living.
Population density ➝ is a measurement of population per unit area or volume. It is frequently applied to living organisms, most of the time to humans.
Carrying capacity➝ is the average population density or population size of a species in a habitat.
Exponential growth➝ is a process that increases quantity over time. It occurs when the instantaneous rate of change.
Density-independent limiting factor➝ is any force that affects the size of a population of living things.
Logistic Growth ➝ is a population's per capita growth rate stays the same regardless of population size, making the population grow faster as it gets larger.
Density-dependent limiting factor➝ is a limiting factor of a population wherein large, large dense populations are more affected than small, less crowded ones ex. predation, competition, food supply.
<u>II. Enumarate at least three(3) factors that affect population growth.</u>
<u>III. Differentiate exponential growth and logistic growth.</u>
Exponential growth is a growth in population wherein the number of individuals increases. Logistic growth entails exponential growth in population along with a growth rate that is in a constant state. As the population comes to its carrying capacity, the growth rate then decreases significantly.
