Which of these phylogenetic trees depicts a different evolutionary history than the others?
A. Tree 1
B Tree 2
C tree 3
D tree 4
Tree 3 depicts a different evolutionary history than the others. So, the correct option is C.
What is Phylogenetic relationship?A phylogenetic tree is defined as a branching diagram or a tree that shows the evolutionary relationships between different biological species or other entities based on similarities and differences in their physical or genetic characteristics. All life on Earth is part of a single phylogenetic tree that points to common ancestry.
These relationships are identified by using the similarities in DNA, RNA, or protein sequences, or by comparing the anatomical features. Through this, we get to know that all life arises from a common ancestor. In the above given information, Tree 3 shows the phylogenetic relationship.
Thus, Tree 3 depicts a different evolutionary history than the others. So, the correct option is C.

Explain how organisms contribute to the
creation of soil.
Explanation:
Soil formation is influenced by organisms (such as plants), micro-organisms (such as bacteria or fungi), burrowing insects, animals and humans.
As soil forms, plants begin to grow in it. The plants mature, die and new ones take their place. Their leaves and roots are added to the soil. Animals eat plants and their wastes and eventually their bodies are added to the soil.
This begins to change the soil. Bacteria, fungi, worms and other burrowers break down plant litter and animal wastes and remains, to eventually become organic matter.

You encounter someone who has never heard of evolution, and they ask you about a population of ducks that live in their grandmothers pond. They tell you that 10 years ago the pong had both large eyed ducks and small eyed ducks. But one day 2 of the large eyed ducks were killed by some wild dogs. Now, the population of ducks has entirely small eyed. Identify the mechanism of change in the duck scenario and use it as evidence to explain evaluation to that person.
Answer:
The large eyed ducks had an undesirable trait, but the small eyed ducks have a desirable trait. Because the large eyed ducks had a trait that decreases their chances of survival, they wete killed. But small eyed ducks are lucky because they have a trait that increases their chance of survival. The small eyed ducks reproduce more offspring that have small eyes, but the large eyed ducks cannot because they didn't survive. This causes that the allele for large eyes in the gene pool to decrease.
explain what is crossing-over in your own words
Explanation:
it occurs during meiosis. Its the exchange of chromosome pieces between the non-sister chromatids during the production of gametes.
Answer:
Crossing-Over is a DNA segment on each chromosome section may code for eye color, although one chromosome may code for brown eyes and the other for blue eyes. Crossing over occurs most often between different alleles coding for the same gene.

What is ocean current?A continuous, directed movement of sea water caused by a variety of forces acting on the water, such as wind, the Coriolis effect, breaking waves, cabling, and temperature and salinity differences.
Wind, density differences in water masses caused by temperature and salinity variations, gravity, and events such as earthquakes or storms can all cause ocean currents. Currents are streams of seawater that flow through the ocean.
Water expands due to solar heat absorbed at the equator. Such heated water raises the normal sea surface level, and the resulting change in ocean topography can be measured.
Warm ocean currents flow from the equator to the poles, while cold ocean currents flow from the poles to the equator.
Thus, the correct option is d.

What is genetic diversity?
Answer:
Genetic diversity refers to both the vast numbers of different species as well as the diversity within a species. The greater the genetic diversity within a species, the greater that species’ chances of long-term survival. This is because negative traits (such as inherited diseases) become widespread within a population when that population is left to reproduce only with its own members.

any resorse necessary to the survival of populations in an ecosystem may become a what?
Answer:
Limiting factor.
Explanation:
If the resource is necessary to the survival of a population and is needed to sustain it and allow the population to grow, it is a limiting factor. Simply put, limiting factors are defined as anything that constrains a population's size and slows or stops it from growing. Over use of resources can cause the species that need it to survive to die out and possibly become extinct if they can only be found in that ecosystem.
It is not a Biotic factor because biotic factors are described as a living organism that shapes its environment. These can include plants like algae.
An abiotic factor is a non-living part of an ecosystem that shapes its environment.
Both of these are defined as factors in an ecosystem and are important. HOWEVER, the question is asking about resources in an ecosystem. Therefore Limiting factor is correct.
