The correct answer is A dan B. This is because the blood type AB is a result of having both the A and B antigens on the red blood cells. Therefore, for a baby to have blood type AB, one parent must have blood type A and the other parent must have blood type B.

The correct answer is "marga sama, jenis berbeda" because Allium cepa (bawang merah) and Allium sativum (bawang putih) belong to the same genus, which is Allium. However, they are different species, with Allium cepa being the species for bawang merah and Allium sativum being the species for bawang putih.

Spirulina sp. is the correct answer because it is a type of algae that is known for its high protein content. It is commonly used as a source of alternative high-protein food, especially in the form of supplements or powders. Spirulina is rich in essential amino acids and contains a variety of vitamins and minerals, making it a nutritious option for protein supplementation.

Bakteri Rhizobium yang bersimbiosis dengan tumbuhan polong-polongan bermanfaat karena mereka dapat mengubah nitrogen bebas menjadi nitrat. Nitrogen bebas dalam udara tidak dapat digunakan oleh tumbuhan, tetapi bakteri Rhizobium dapat mengambil nitrogen bebas dari udara dan mengubahnya menjadi bentuk yang dapat diserap oleh tumbuhan, yaitu nitrat. Nitrat merupakan salah satu bentuk nitrogen yang penting bagi pertumbuhan dan perkembangan tumbuhan. Dengan demikian, bakteri Rhizobium membantu meningkatkan ketersediaan nitrogen bagi tumbuhan polong-polongan.

The characteristics mentioned in the question, such as septate hyphae, multicellular, saprophytic, chitinous cell walls, formation of sporangia and gametangia, and production of zygospores, are all traits of Zygomycotina. Therefore, the correct answer is Zygomycotina.

The correct answer is "menyampaikan impuls ke sumsum tulang belakang." Neuron sensorik pada lengkung refleks lutut berperan dalam menyampaikan impuls atau sinyal dari reseptor yang terdapat di lutut ke sumsum tulang belakang. Ini penting karena sumsum tulang belakang berperan dalam mengkoordinasikan respons refleks seperti menarik kaki ketika lutut terkena pukulan atau terjadi tekanan.

The correct answer is astigmat teratur. Astigmat teratur is a condition where the cornea of the eye is not perfectly curved, causing parallel light rays to be unable to focus on a single point. This can result in blurred or distorted vision. Using a cylindrical lens can help correct this condition.

The correct answer is "pembuatan tape dengan menambahkan jamur ragi Saccharomyces sp." This answer indicates the involvement of biotechnology because the process of making tape involves the use of a specific type of yeast, Saccharomyces sp., which is a microorganism used in biotechnological applications. Biotechnology refers to the use of living organisms or their components to create useful products or processes, and in this case, the use of the yeast in tape production is an example of biotechnological application.

The correct answer is 3 : 1. This is because when a tall green plant (TTHh) is crossed with a short green plant (ttHh), the genotype of the offspring will be TtHh. The "hh" genotype causes the absence of chlorophyll in the plant, resulting in a short green phenotype. Therefore, the ratio of plants that can survive (TtHh) to those that cannot survive (ttHH) is 3 : 1.

At the beginning of the Calvin cycle, atmospheric CO2 enters the leaf through stomata and combines with RuBP (ribulose-1,5-bisphosphate).

When the heart is unable to produce bile, it will cause a disturbance in the digestion of fats. Bile is produced by the liver and stored in the gallbladder, and it plays a crucial role in the digestion and absorption of fats in the small intestine. Without bile, the body cannot effectively break down and absorb dietary fats, leading to digestive issues such as bloating, diarrhea, and malabsorption of essential nutrients.

Plasmodium is a type of parasitic protozoan that causes malaria. It enters the human body through the saliva of a mosquito when it bites. Once inside the body, the sporozoites of Plasmodium multiply by dividing and form merozoites. These merozoites then invade red blood cells, causing them to burst and release more merozoites, leading to the symptoms of malaria. Therefore, the correct answer is merozoik.

Progesteron adalah hormon yang dapat menebalkan dinding uterus. Hormon ini diproduksi oleh ovarium setelah ovulasi dan berperan dalam mempersiapkan dinding rahim untuk menerima dan mempertahankan kehamilan. Progesteron juga membantu menghentikan kontraksi otot rahim sehingga mencegah keguguran. Hormon ini sangat penting dalam siklus menstruasi dan kehamilan.

Progesterone is the hormone that is most active early in the menstrual process of an adult woman.

The correct answer is "otak" because it is not a part of the network of tissues and organs mentioned in the question. The question is asking which one does not belong, and all the other options (membran mukosa yang melapisi dinding lambung, kartilago, darah, otot jantung) are part of the body's network except for the brain (otak). The brain is a separate organ that is not directly connected to the other mentioned tissues and organs.

The correct answer is the choroid. The choroid is the part of the eye that supplies nutrients and oxygen to the retina. It is a layer of blood vessels located between the sclera and the retina.

The correct answer is Wucheceri. The question states that eradicating mosquitoes indirectly helps prevent the spread of diseases caused by a certain type of worm. Out of the given options, Wucheceri is the only one that belongs to the group of worms known as Nematoda, which includes roundworms like Ascaris, Ancylostoma, and Enterobius. Therefore, Wucheceri is the most likely correct answer.

The visible difference between lactic acid fermentation and alcohol fermentation is that alcohol fermentation does not require the addition of electrons.

Thrombin is not normally present in blood vessels in humans. Thrombin is an enzyme that plays a crucial role in the blood clotting process. It is produced from its precursor, prothrombin, in response to injury or damage to blood vessels. Thrombin converts fibrinogen into fibrin, which forms a mesh-like structure to help in the formation of blood clots. However, in normal conditions, thrombin is not present in blood vessels as it is only produced when there is a need for clotting.

The correct answer is "badan Malpighi." The Biuret reagent is used to test for the presence of proteins in a urine sample. If the reagent turns purple, it indicates the presence of proteins in the urine, which is abnormal. The Malpighian bodies, also known as renal corpuscles, are located in the renal cortex of the kidney and consist of the glomerulus and the Bowman's capsule. The glomerulus is responsible for filtering blood and if there is a problem with it, such as damage or inflammation, it can lead to the presence of proteins in the urine. Therefore, the abnormality in the kidney that can be suggested by the purple color with the Biuret reagent is the Malpighian bodies or specifically the glomerulus.

When someone consumes Baygon, which is an organophosphate poison, it inhibits the enzyme acetylcholinesterase that breaks down the neurotransmitter acetylcholine. One of the synapses that uses acetylcholine as a neurotransmitter is the synapse that connects motor neurons to skeletal muscles. Consuming Baygon would cause continuous depolarization of the muscle cell membranes, leading to muscle spasms.

Escherichia coli sering digunakan sebagai inang untuk DNA yang akan direkayasa karena bakteri tersebut dapat dimasuki vektor. This means that Escherichia coli can serve as a host for engineered DNA to be inserted into.

In the life cycle of Aurelia aurita, the free-swimming stage with cilia and without tentacles is called a planula.

The correct answer is 2 : 1 : 1 : 0. This ratio indicates that in the F2 generation, there will be twice as many flies with normal gray wings as there are flies with curly gray wings. Additionally, there will be an equal number of flies with normal black wings and flies with curly black wings. There will be no flies with black curly wings in the F2 generation.

The correct answer is "tingkah laku dan gen." Keanekaragaman jenis refers to the diversity of species. In order to observe the diversity of species, one can look at the differences in both behavior (tingkah laku) and genetics (gen). These two factors play a significant role in distinguishing and categorizing different species.
