Answer:
C. stigma
Explanation:
"stigma"
Fertilization in flowering plants happens through a process called pollination. Pollination occurs when pollen grains from the anther land on a stigma. After pollen grains land on the stigma, a pollen tube grows from the pollen grain, through the style, and into the ovary.

Describe an experiment used to prove that amino acids and sucrose go up and down the phloem.
Answer:
By using carbon-14 in the experiment in order to prove the statement.
Explanation:
Translocation occurs in the plant body in order to transport amino acids and sucrose from one part to another by the phloem tissues. In order to prove this, we have to incorporate radioactive element in the amino acid or sucrose which shows us that through which layer the amino acids and sucrose move in the plant body. For this purpose, carbon-14 can be used to trace the path of the translocation of amino acids and sucrose. Through this experiment we will find out that phloem layer is the path used by the plant to move amino acids and sucrose from one part to another.
Cory states the following argument about the evolution of aardvarks and anteaters.
"Aardvarks and anteaters both use long, sticky tongues to capture and eat ants or termites. Aardvarks are native to Africa, while anteaters are native to the Americas. However, their similarities provide evidence that both groups of species evolved from a common ancestor that used its tongue to eat ant-like insects."
Which claim, if supported by evidence, would provide the strongest counter-argument AGAINST Cory's argument?
A. The tongues and diet of aardvarks and anteaters are an example of convergent evolution.
B. The tongues and diet of aardvarks and anteaters are an example of adaptive radiation.
C. The Americas and Africa were once joined together, and animals roamed freely between the two lands.
D. A long, sticky tongue evolved in response to the tunneling behavior of ants, an example of coevolution.

Which description explains why there are two high and two low tides in a day? (4 points)
Earth moves closer to the sun and moon twice a day.
Earth revolves around the tidal bulges created by gravitational forces.
Earth rotates in and out of a tidal bulge twice a day.
The moon's gravity increases over the oceans and decreases over the land.
Answer:
Earth rotates in and out of a tidal bulge twice a day.
Earth always has two surrounding gravitational forces, one proceeding from the moon and one from the sun.
The sun's pull, despite the fact our sun is further then the moon, is stronger and creates the high tide, and the moon the low tide. But as we know our earth moves, now exposing the other side to the sun which in turn leaves the other side of earth with the high tides and the other with the low tides. Tides never move, what moves is earth.

In the given cladogram the number 4 is node.
What is Cladogram?A phylogeny, or hypothetical link between groups of creatures, is depicted in a diagram known as a cladogram. A phylogenetic systematics researcher will use a cladogram to depict the groups of organisms being compared, their relationships, and their most recent shared ancestors.
A cladogram might be quite complicated and compare every known form of life, or it can be extremely simple and compare just two or three groups of creatures.
Cladogram design is straightforward but ubiquitous. The creatures being examined, lines, and nodes where those lines intersect make up a cladogram.
Therefore, In the given cladogram the number 4 is node.

Scientists have recorded increasing ocean temperatures. Which of the following is not a consequence of these increasing global temperatures?
altered species interactions
lower salinity in ocean water
shifts in the range of habitat for organisms
changes in the seasonal abundance of populations
Answer:
Lower Salinity in the ocean water.
Explanation:
The ocean absorbs most of the excess heat from greenhouse gas emissions, leading to rising ocean temperatures. Increasing ocean temperatures affect marine species and ecosystems. Rising temperatures cause coral bleaching and the loss of breeding grounds for marine fishes and mammals.
Evaporation of ocean water and formation of sea ice both increase the salinity of the ocean. However these "salinity raising" factors are continually counterbalanced by the continuous input of fresh water from rivers, precipitation of rain and snow, and melting of ice.
As temperature increases, the space between water molecules increases—also known as density, which therefore decreases. ... Salinity and density share a positive relationship. As density increases, the amount of salts in the water—also known as salinity, increases

How is Cytochrome C, which is an important enzyme in cellular respiration, used to provide evidence for evolution. bones (homologous structures) are used for similar uses if the organisms are more closely related bones (homologous structures) are used for similar uses if the organisms are more closely related sections of DNA are more similar in organism more closely related. sections of DNA are more similar in organism more closely related. organisms that are more closely related are found with similar embryonic structures. organisms that are more closely related are found with similar embryonic structures. fossils in various layers are more closely related if they are in the same layer
Answer:
Sections of DNA are more similar in organism more closely related
Cytochrome c is used to provide evidence for evolution because most animals have this protein and is has undergone very little changes in these organisms such that more closely related species have the most similarity in amino acid sequence of cytochrome c
Explanation:
Cytochrome c is a protein found in mitochondria and is an important enzyme in cellular respiration. Cytochrome c is a highly conserved (have undergone very little changes) protein that in found in many different species of organismsmsuch as plants, animals, and many unicellular organisms. Cytochrome c is made up of about 104 amino acids linked together by peptide bonds. Being a small-sized molecule (molecular weight about 12,000 daltons) also makes it easier for evolutionary studies to be conducted on it.
Organisms that are most closely related have the most similarity in the amino acid sequence of the cytochrome c molecule. The amino acid sequences in cytochrome c molecule present in organisms is as a result of the information in their DNA.Thus, sections of DNA are more similar in more closely related organisms.
