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.

variation over time.
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.

Based on the empirical data and information you have learned about
ecosystems and the services they provide, do you support or refute the claim that increases in wetlands, forested buffers, and submerged aquatic vegetation will result in increases in the blue crab population and other fisheries over time? Include appropriate evidence andscientific reasoning to support your claim.
Answer:
Yes.
Explanation:
Yes, I support the claim that increases in wetlands, forested buffers, and submerged aquatic vegetation will result in increases in the blue crab population and other fisheries because these wetlands, forested buffers and submerged aquatic vegetation provides habitat and food to the crabs and other fishes. Due to availability of suitable environment and more food availability to the crab and fishes which leads to increase their population.

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.

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.
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.

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.
