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.*
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.

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.
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.
Why does sexual reproduction result in offspring with genetic variation? Use the examples that you studied to support your answer.
Answer:
Sexual reproduction results in offsrping with genetic variation due to the multiplication brings about limitless prospects of hereditary variety. The examples, that can be studied to support this would be at the end of the day, sexual generation brings about posterity that are hereditarily extraordinary. They vary from the two guardians and furthermore from one another. This happens for various reasons.

Explanation:
Anti-malarial drugs kill the parasites in the blood but they do not cure the disease. That because;
a) It not treat the disease
b) The parasite has two hosts, human one of them
c) The blood not the place to fight Malaria
d) Malaria is a strong disease
Answer:
c) The blood not the place to fight Malaria
Explanation:
This wording is weird but I think it is C. Anti-malarial drugs are not for curing the disease because they only kill the parasites in the blood. Malaria develops in the blood stage and the liver. The anti-malarial drug kills the blood-stages of the parasite but not the liver ones. The liver ones can reinfect the blood and cause malaria again.

Answer:
The biological species concept defines a species as members of populations that actually or potentially interbreed in nature, not according to similarity of appearance. Although appearance is helpful in identifying species, it does not define species. ... Organisms may look different and yet be the same species.
1. Some bacteria in the colon help in making vitamin K. What is the
function of vitamin K?
A. helps fight infections
B. important for heart health
C. essential in helping blood to clot after an injury
D. Important for bone growth
Brainiest if right
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.

Evolution involves change over time
and descents from a common ancestor.
What is the evolutionary process?Evolution is the process of changing the genetic material of a population over time. Evolution reflects the organism's adaptation to a changing environment and can lead to genetic changes, new traits, and new species.
How do process changes occur during evolution?Genetic variation can result from genetic variation (also called a mutation) or from the normal process by which genetic material is rearranged (known as gene recombination) as cells prepare to divide. there is. Genetic variation that alters genetic activity or protein function can introduce a variety of traits into an organism.

This is worth 100 points. Please answer and do not skip over this question.
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?
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.

different parts are related to each other.
Chloroplast
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.
