Answer:
They both are determined by whether or not they have a common ancestor attributing to differing species evolution. Divergent evolution is when different organisms who have a common ancestor end up as different species. Convergent evolution is when different organisms end up more alike over time, despite not having any common ancestors.
Explanation:
1. Students need to describe how genetic traits are determined by information encoded in
DNA passed on from parent to offspring.
Answer:
One copy is inherited from their mother (via the egg) and the other from their father (via the sperm). A sperm and an egg each contain one set of 23 chromosomes. When the sperm fertilises the egg, two copies of each chromosome are present (and therefore two copies of each gene), and so an embryo forms.
Explanation:
How can a particular trait be both advantageou and disadvantageous?
Answer:
An organism that develops a trait that helps it survive in its environment will have a better chance of reproducing and passing that trait on to the next generation. As a consequence, organisms with this helpful trait will become more prominent while other organisms of the same species die out.

Once the cell has gone through interphase, it is ready for division. What is this process called?
Cellular Respiration
Mitosis
G0
S phase
Answer:
S phase
Explanation:
During the interphase which is also called the S phase, the cell duplicates its chromosomes and ensures its systems are ready for cell division. If all conditions are ideal, the cell is now ready to move into the first phase of mitosis.

What is the main component of the thin filaments in muscle fibers and is responsible for muscle contraction? actin myosin atp dna
The main component of the thin filaments in muscle fibres that is responsible for muscle contraction is Actin.
What are actin and myosin filament and how they are responsible for muscle contraction?Actin and Myosin both are proteins that are found in muscle tissue. Myosin protein is the thick filaments whereas actin protein is the thin filaments that work together to generate muscle contraction and movement.
Along with the actin, there are some other proteins such as troponin and tropomyosin that forms the thin filament. However, actin plays an important role in the contraction of muscles as each actin molecule consists of a single myosin-binding site.
All actin molecules join together to form a chain twisted into a helix configuration which is important for the contraction mechanism in muscles.
However, actin is the thin filament that plays an important role in the contraction of muscles.

The shells of single-celled plankton that sank to the bottom of the ocean has two
varieties of which type of atoms?
Carbon isotopes
Sodium isotopes
Phosphorous isotopes
Oxygen isotopes
Answer: Oxygen Isotopes!
Explanation:
I just took the quiz and I got it correct!
Carbon and oxygen Isotopes are the two atoms present in shells of single-celled plankton that sank to the bottom of the ocean.
Composition of shellThe shells of single celled plankton is made up of calcium carbonate or from tiny grains of sand stuck together. Mostly, they are made of calcium carbonate and we know that carbonate is formed from one carbon atom and three oxygen atom.
So we can conclude that carbon and oxygen Isotopes are the two atoms present in shells of single-celled plankton that sank to the bottom of the ocean.

Green coloration would be the most beneficial adaptation for insects that live in the grass as it can absorb more range of the spectrum as it will also help in photosynthesis.
The model that could be maximum beneficial to an insect that lives withinside the grass is green color. inexperienced coloration. This could be a beneficial model for them due to the fact now they may camouflage easily - the grass is inexperienced, and if they're additionally inexperienced and hiding in the grass, no one can spot them easily, that's a great manner for them to cover from predators which can need to devour them.

How do muscles generally create movement
A) constant contraction of muscle groups
B)constant relaxation of muscle groups
C)Uncoordinated contraction and relaxation of muscle groups
D)Coordinated contraction and relaxation of muscle groups
Answer:
D) Coordinated contraction and relaxation of muscle groups
Explanation:
In order for muscles to properly work, the muscle groups have to contract and then relax in coordination.
If muscles were to constantly contract, then the muscles would get overworked and fail to function correctly.
If muscles were to constantly relax, then the muscles wouldn't be able to work at all.
If the contraction and relaxation of muscle groups were uncoordinated, then the organism wouldn't be able to have muscle control, which is needed.
