Genetics (J.M)
A dog with homozygous dominant genes for Black fur mates with a dog that has the homozygous recessive gene for white fur. What color fur will the offspring most likely have?
The dog would most likely have black fur.
What might happen to a species if its environment changes quickly?
It might go extinct if it can't adapt fast enough?
What is the name of a process which plants do that takes in carbon and expels oxygen?
Photosynthesis
How do decomposers help both plants and animals in an ecosystem?
Decomposers break down dead material and recycle nutrients into the soil, which helps plants grow. That helps animals too, because many eat the plants.
What organelle is the powerhouse of the cell
The mitochondria
Out of either meiosis or mitosis, which allows for a more diverse offspring.
Meiosis
Why do some animals have similar bones even if they look different?
They share a common ancestor but evolved for different functions
If plants are removed from the carbon cycle what would happen to the atmosphere
The amount of carbon dioxide would greatly increase while oxygen levels would decrease
A drought causes most of the plants in a forest ecosystem to die. Predict how this might affect herbivores and carnivores over time.
Herbivores would have less food and could starve or migrate. Carnivores that eat herbivores would also suffer, and the whole ecosystem could become unbalanced or collapse.
If a nonbeneficial source attempted to enter the cell how would the cell prevent this from entering
The cell membrane would be the first defense in stopping anything bad from entering
What enzyme makes new DNA strands from either 5 " to 3" - or - 3" to 5"
Polymerase
What does natural selection mean in terms of survival?
Organisms with favorable traits are more likely to survive and reproduce
What are the four main process of the carbon cycle
Photosynthesis, Respiration, Decomposition, and Combustion
If a main food source like grass suddenly stops growing in an area, what might happen to the rest of the food chain?
Herbivores like rabbits would lose their food and might die or move away. That would affect carnivores like foxes that eat the rabbits, and the whole food chain could collapse or change.
In a plant cell, what organelle is used to perform photosynthesis
The chloroplast
This type of RNA brings amino acids to the ribosome during protein synthesis.
tRNA (Transfer RNA)
What is the difference between inherited traits and acquired traits.
Inherited traits are passed from parents genetically, while acquired traits develop from experience or environment
Organisms may take in oxygen and breathe out a gas. What is the name of the gas?
Carbon dioxide
Why might food webs be taken as more realistic than food chains when showing how energy moves in nature?
Animals usually eat more than one type of food. Food webs show the complex ways energy moves through many organisms in an ecosystem.
During the evolution of cells how did certain organelles like mitochondria and chloroplast come to be in eukaryotic cells
By a prokaryotic cell combining with a eukaryotic to create the organelles
What are the building blocks of DNA
Adenine (A) , Thymine (T) , Cytosine (C) , Guanine (G)
How do fossils support the idea of evolution?
They show how organisms have changed over time?
How do the carbon cycle interacts with other biogeochemical cycles, such as the nitrogen and water cycles.
These cycles interact through processes like photosynthesis, decomposition, and water movement, influencing nutrient availability and overall ecosystem health
A new predator is introduced to an island with no natural enemies. How this might affect biodiversity and ecosystem balance over time.?
The new predator might hunt local animals too frequently, causing some to go extinct. That would reduce biodiversity and damage the whole balance of the ecosystem.
The movement of water, the solvent, across a semipermeable membrane from an area of higher water concentration to an area of lower water concentration.
Osmosis
