Please tell me, in your own words, what you know about the ideas of natural selection
and evolution.
Explanation:
Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations.
In the theory of natural selection, organisms produce more offspring than are able to survive in their environment. Those that are better physically equipped to survive, grow to maturity, and reproduce. ... Biologists have since observed numerous examples of natural selection influencing evolution.

Once water seeps down under the ground, it stays there
forever.
Answer:
i Feel like its false but it could be true
Explanation:
As you know or dont, Water at very shallow depths might be just a few hours old; at moderate depth, it may be 100 years old; and at great depth or after having flowed long distances from places of entry, water may be several thousands of years old. As water seeps into the ground, some of it clings to particles of soil or to roots of plants just below the land surface. This moisture provides plants with the water they need to grow. Water not used by plants moves deeper into the ground. The water then fills the empty spaces and cracks above that layer

Some organisms, such as fish and mosquitoes, produce very large numbers of offspring. According to the theory of natural selection, why is producing a large number of offspring essential?
Answer:
producing a large number of offspring tend to make a relatively small energy investment in each other and don't usually provide much parental care.
How do Punnett squares help predict the outcomes of artificial selection?
Punnett squares can be used to combine the alleles from the mother and the father to ascertain the likelihood as well as potential genotypes and phenotypes that a child may acquire from their parents.
What are Punnett squares?
The Punnett square is a tabular summary of possible combinations of maternal elapse with paternal. The percentages of phenotypes in a cross's progeny from known genotypes can be predicted using a Punnett square.
Based on the other genotypes involved in the cross, a missing genotype can be identified using a Punnett square. A Punnet square displays the potential gene combinations in the child inside the square, together with the genes (represented by letters) in the parent gametes along the top and left sides of the square.
Therefore, Punnett squares can be completed to determine the likely outcome of a cross.

It also includes all the gas clouds because water can be solid, liquid, or gas
so oceans, ice caps, and water vapor is included.
Answer:
hydrosphere
Explanation:
A planet's hydrosphere can be liquid, vapor, or ice. On Earth, liquid water exists on the surface in the form of oceans, lakes and rivers. It also exists below ground as groundwater, in wells and aquifers.
How does the structure of a DNA sequence determine the function of a protein
Answer:
Shape
Explanation:
The structure of a DNA sequence determines the function of a protein by it's shape. The shape of a protein is determined by the sequence of the amino acids which is also the primary structures. And then the sequence of amino acids are determined by the sequence of nucleotides in the genes, which encodes it.

what are functions do you think needed in coordination and balance
it an important question please answer it
Answer:
Posture and equilibrium.
Explanation:
Cerebellum is a part of brain that is responsible for the coordination and balance in the body. The other function of cerebellum is the regulation of motor movements in the body. It also functions to maintain posture and equilibrium in the human body that affects coordination and balance. Posture refers to the position in which a person holds its body in standing or sitting position.

How do evolutionary developments of the trilobites represent stability over the long term, and change over the short term ?
Answer:
I am having trouble with the same question as well.
Explanation:
Can anyone help us.
The evolutionary modifications in trilobites could have occurred relatively quickly but there are periods with little to no change to the species.
Trilobites represent an extinct group of animals that disappeared during the end Permian mass extinction event.This event (Permian mass extinction) removed over 90% of all species on Earth. The equilibrium punctuated theory suggests that there are periods of very little change in the evolution of a species, and then periods having huge evolutionary modifications.In conclusion, the evolutionary modifications in trilobites could have occurred relatively quickly but there are periods with little to no change to the species.
