Answer:
There are several possible reasons for chemotherapy resistance: Some of the cells that are not killed by the chemotherapy mutate (change) and become resistant to the drug. Once they multiply, there may be more resistant cells than cells that are sensitive to the chemotherapy. Gene amplification.

Which of the following is most likely to contribute to density-dependent regulation of populations? Group of answer choices Individuals voluntarily stop mating so that overcrowding does not occur. Density-independent factors lead to fewer births and increased mortality. The incoming energy decreases in populations experiencing a high rate of increase. Density-dependent factors lead to fewer births and increased mortality.
Answer:
Density-dependent factors lead to fewer births and increased mortality.
Explanation:
The carrying capacity can be defined as the maximum population size an environment can support. Density-dependent limiting factors produce a logistic growth pattern (S curve) in the population until it reaches its carrying capacity, thereby decreasing the birth rate and increasing the mortality rate in the population. Some important density-dependent limiting factors able to control the size of the population are competition (intraspecific competition), predation and diseases.

Inherited traits are described by probabilities. When experimenting on inherited traits, why is it important to have a large sample size?
Tysm! I love you<33
Answer:
results will be more accurate if there is a larger sample size.
No matter what research is, the larger sample size is, the more accurately will be the results and vice versa. The larger samples increase a chance of significance because they reflect the population mean more reliably.
With small sample, the chance for false conclusions is higher.

Which of the following energy transformations occur when humans use energy from food to exercise?
A. Mechanical - thermal - chemical
B. Thermal - electrical - mechanical C.Radiant - mechanical - thermal
D. Chemical - mechanical - thermal
Answer:
D. Chemical - mechanical - thermal
Explanation:
Food contains chemical energy; when our bodies break down and digest food, the bonds that are broken apart release chemical energy. Our bodies convert this to mechanical energy to power movement, from movements as small as blinking or our hearts beating, to bigger movements like running or swimming. When we exercise or move, we also release heat which is thermal energy.
The energy transformations that occur when humans use energy from food to exercise is: D. Chemical - mechanical - thermal.
What is energy?Energy can be defined as the ability to do work. Thus, energy must be possessed or transferred to a physical object (body) before it can be used in doing a work or heating a system.
The forms of energy.In Science, there are different forms of energy and these are;
Gravitational energyElectrical energySound energyChemical energyThermal energyMechanical energyIn conclusion, the energy transformations that occur when humans use energy from food to exercise is chemical energy to mechanical energy and lastly to thermal energy.

List down 3 ways on how you can protect the estuaries and intertidal zones so that interaction of the and abiotic factor in these areas will not be disturbed.
Answer: Intertidal zones are regions which lie above the water level which receives low tides. Estuaries are the closed bodies of coastal waters which contain brackish water.
Explanation:
The ways through which the intertidal zones and estuaries can be protected are as follows:
1. The chemical discharge from factories and sewage discharge must be restricted or prohibited in these areas so that the water and air quality remains good necessary for the survival of living beings.
2. Prohibiting the waterways to prevent the discharge of oils which can contaminate water of estuaries and soil of intertidal zones.
3. The trash of polythene bags, plastic materials, vegetable matter discharged from the city must be cleaned up to retain the quality of soil and water.
