Based on your cladogram, from oldest to newest, in what order did the three characteristics (flowers, multicellularity, and xylem/ phloem) evolve? *The purple lines represent a characteristic change or adaptation.*
Answers
Complete question:
You will find the cladogram in the attached files
Answer:
multicellularityxylem/phloemflowersExplanation:
Based on this cladogram, the order of changes was multicellularity, vascular system, flowers.
Multicellularity. The first division or point of divergence is located between moss and the rest of the organisms. Moss is included in the Bryophyta group, characterized for being the first terrestrial plants. They are not vascular plants, and their general structure is simple but pluricellular. Multicellularity implicates association between different cells that specialized in accomplishing different functions. This complex association works to make the organism survive. Algae might be unicellular or pluricellular. Although is not the same, unicellular algae might form colonies, that are groups of cells agglomerated.
Xylem/ Phloem: The second change is related to the vascular system. Cycads are gymnosperms. These are vascular plants that produce naked seeds. The vascular system developed by gymnosperms is very elaborated, with secondary growth, and including supporting cells that allow these plants to get bigger dimensions, particularly in height.
Flowers: The last change is related to the emergence of flowers. Arabidopsis is included in the angiosperm group, the most evolved one, with great capabilities of reproduction and dispersion. They have flowers, which carry the reproductive structures. Once occurred fertilization, fruits develop and carry the seeds. Flowers might be unisexual or hermaphrodites. Their vascular system is also very complex and adapted to different environments.

B.During deposition, a gas changes directly into a solid.
C.The condensation points for oxygen and hydrogen are the same.
D.All of the above.
Answers
Answer:
B. During deposition, a gas changes directly into a solid
Explanation:
First we can cross of A, because the boiling point is the same it just takes longer to get there.
So since A. is incorrect, that means D. has to be incorrect too. That leaves us with B. and C.
Finally, I already know what deposition is so since it is not D. it has to be B.

D. Important for bone growth
Brainiest if right
Answers
Answer: A. Essential in helping blood clot after an injury
Explanation:
Vitamin K's function is essential in helping the blood to clot after an injury. So, the correct option is C.
What is Vitamin K?The fat-soluble vitamin K is an important component of bone metabolism and blood coagulation. Both vitamin K1 (phylloquinone), which is found in green leafy vegetables, and vitamin K2 (menaquinone), which is produced by bacteria in the colon and is also present. In some animal-based diets, there are two main forms of vitamin K.
Structurally related, a series of fat-soluble vitamins known as vitamin K are present in foods and sold as dietary supplements. Vitamin K is needed by the human body for the synthesis of many proteins necessary for blood coagulation or to regulate calcium binding in bones and other tissues. Vitamin K's function is essential in helping the blood to clot after an injury.
Therefore, the correct option is C.

Humans often like to help wild animals. A marine biologist near the area where Anchor’s offspring are located has decided to feed them. He begins putting medicine in the food that keeps the pups from contracting infections common to sharks in the area. Because of this, nearly all of Anchor’s offspring survive to adulthood. Eventually, the marine biologist gets a job transfer and leaves the area. Predict what we may see in the following generation (Anchor’s grandpops). Will they still be fitter than other sharks?
Answers
Answer:
I would predict that the the following generation will have a large amount of pups that are eaten by the sharks.
This question seems like its asking about natural selection.
"Natural selection is the process when organisms better adapted to their environment tend to survive and produce more offspring"
Explanation:
If the marine biologist did not give the pups medicine in the first generation, the pups that were less fit or not adaptive to the enviroment to naturally survive the infections would have died. This would have prevented these pups from passing on their genes.
The next generation would consists of pups that are more immune to the sickness or more fit for their enviroment and might experiece less pups to die.

In the process of glycolysis, four ATP molecules are synthesized from four ADP molecules. Why does glycolysis not yield four molecules of ATP?
A TWO ATP molecules are lost in the cytoplasm.
B. Two ATP molecules are converted immediately back to ADP.
C. Two ATP molecules are required to start the process.
D. Two ATP molecules are absorbed in the mitochondria
Answers
Answer:
c
Explanation:
two ATP molecules are required to start the process. initially when glucose is phosphorylated it requires energy which is provided by the hydrolysis of ATP so 2 molecules are used up.
Glycolysis does not yield four molecules of ATP because two ATP molecules are required to start the process. Hence option C is correct.
What is ATP?ATP stands for adenosine triphosphate. It is defined as an organic substance that fuels a variety of functions in living cells, including chemical synthesis, condensate dissolution, nerve impulse transmission, and muscular contraction. When the cell needs energy, ATP can be taken out and used to fuel processes or stored for use in later ones.
Glycolysis is defined as the pyruvic or lactic acid is produced as a result of the enzymatic breakdown of a carbohydrate using phosphate derivatives, and energy is stored in ATP's high-energy phosphate bonds. A linear metabolic process called glycolysis uses enzymes to catalyze reactions that break down glucose into two molecules of pyruvate or lactate depending on whether oxygen is present.
Thus, Glycolysis does not yield four molecules of ATP because two ATP molecules are required to start the process. Hence option C is correct.

Chloroplast
Answers
Answer:
Chloroplast -----membranes----------internal
---------external
----- Tylacoids-------------Grana
----- Stroma
You will find the complete concept map in the attached files
Explanation:
Chloroplasts are composed of three membrane systems. Surrounding the organelle we can find the external membrane. To the interior of the organelle, there is the internal membrane. These two systems are separated by the intermembrane space. According to the endosymbiotic theory, the presence of a double membrane is the characteristic that reinforces the idea of a prokaryote being phagocyted by a eukaryote. The internal membrane looks identical to the membrane of bacterias, while the external membrane looks like the eukaryotic one.
Thylakoids are located in the interior of the organelle. These structures are also surrounded by a membrane, and in their interior, there is the thylakoid space. Each thylakoid looks like a hollow sac, and together with other thylakoids, they form piles, known as grana. Different piles or grana connect to each other by longer membranes. These internal structures together compose the third system of membranes. The photosynthetic pigments are located in the thylakoids, where it occurs the light-dependent reactions.
Surrounding the thylakoids there is a dense liquid called the stroma. Here takes a place the Calvin cycle.

Where does the mRNA go after it is produced?
Answers
Answer:
The mRNA goes after it is produced is made messenger RNA (mRNA) is a single-stranded RNA molecule that is complementary to one of the DNA strands of a gene. The mRNA is an RNA version of the gene that leaves the cell nucleus and moves to the cytoplasm where proteins are made.
Explanation:
mRNA formed in the nucleus is transported out of the nucleus and into the cytoplasm where it attaches to the ribosomes. Proteins are assembled on the ribosomes using the mRNA nucleotide sequence as a guide. Thus mRNA carries a “message” from the nucleus to the cytoplasm.
What causes there to be a H+ ion concentration gradient to build up inside the thylakoid space? Check all that apply. a. The electrons provide energy for the H+ pump to transport more H+ ions into the thylakoid space. b. A special enzyme produces more H+ ions. c. Photons of light create more H+ ions. d. The photolysis of water releases H+ ions into the thylakoid space.
Answers
Answer:
a. The electrons provide energy for the H+ pump to transport more H+ ions into the thylakoid space.
d. The photolysis of water releases H+ ions into the thylakoid space.
Explanation:
This question describes the first stage of photosynthesis, which is LIGHT-DEPENDENT REACTION. The light dependent reactions involve creating ATP (energy carrier) and NADPH (electron carrier) needed for the Calvin cycle (light independent stage) to occur.
The ATP is formed by pumping hydrogen ions (H+) into the thylakoid space/lumen, hence, creating a electrochemical gradient needed for ATP synthase to synthesize ATP. The buildup of H+ ions is caused by:
- The electrons that arise when light photons hit a chlorophyll molecule is used to provide energy for the H+ pump to transport more H+ ions into the thylakoid space.
- The photolysis of water results in the production of electrons (e-) and hydrogen ions (H+). These hydrogen ions are released into the thylakoid space.
Which is the preserved evidence of the activity of an organism a) cast b) mold c) fossil film d) trace fossil
Answers
Answer:
fossil film
Explanation:
A carbonaceous film or carbon film is an organism outline of a fossil. It is a type of fossil found in any rock when organic material is compressed, leaving only a carbon residue or film. ... Fossils usually form when sediment buries a dead organism.
The preserved evidence of the activity of an organism is trace fossil. The correct option is d.
What is trace fossil?Animal behavior is what creates a trace fossil. A trace fossil might be something like a dinosaur footprint or an arthropod burrow. Beetles' pre-fossilization burrows can be seen as holes in this petrified wood.
When an organism leaves an impression in mud or sand, a trace fossil is created. Sediment dries out and becomes harder.
A fresh sediment layer has been added on top of it. The remnant fossilizes as the sediment hardens into rock as a result of cementation and compaction.
Body fossils are the hard parts of an individual creature or plant that have been preserved over time. Trace fossils are the best-preserved examples of an organism's past activity.
Thus, the correct option is d.
