_______ is a very old drug that's used subcutaneously to prevent DVT in high-risk patients and intravenously to treat DVT and PE. A. Heparin B. Warfarin C. Pradaxa D. Xarelto
The correct answer is the option (A) heparin.
DVT refers to a condition called the deep vein thrombosis when a blood clot occurs in the deep veins of the legs in the body. PE refers to the Pulmonary embolism when a blood clot is observed in the artery of the lungs.
The drugs used in the treatment of DVT and PE are called the anticogulants which interfere with the process of blood clot formation. Heparin and warfarin are the two older anticoagulants used in the prevention and treatment and prevention of DVT and PE. Heparin is given intravenously to treat DVT and PE whereas, warfarin is taken as a tablet or pill through the mouth. Heparin allows the body's clot lysis mechanism to break down the existing clots and it is also a natural anticoagulant produced by the basophils and the mast cells of the blood.
Thus, heparin is the old drug that is used subcutaneously to prevent DVT in high-risk patients and intravenously to treat DVT and PE.
Common characteristics supporting the idea that the first land plants were related to green algae include __________.a. Presence of chlorophyll b. Cell walls made of cellulose c. Alternation of generations d. All of the above e. A and b only
Common characteristics supporting the idea that the first land plants were related to green algae include All of the above. Thus, option "D" is correct.
Which algae is responsible for main supply of oxygen in the atmosphere?
The Green algae are responsible for the main supply of oxygen in the atmosphere. There are tiny organisms called cyanobacteria (or blue-green algae) which photosynthesise carbohydrates for their nutrition and growth using sunlight, water, and carbon dioxide.
The waste product of cyanobacteria is the oxygen of the atmosphere.
Common characteristics supporting the idea that the first land plants were related to green algae include all of the choices.
Minos, king of Crete, had made war upon Athens. He had come with a great fleet of ships and an army, and had burned the merchant vessels in the harbor, and had overrun all the country and the coast even to Megara, which lies to the west. He had laid waste the fields and gardens round about Athens, had pitched his camp close to the walls, and had sent word to the Athenian rulers that on the morrow he would march into their city with fire and sword and would slay all their young men and would pull down all their houses, even to the Temple of Athena, which stood on the great hill above the town. Then Aegeus, the king of Athens, with the twelve elders who were his helpers, went out to see King Minos and to treat with him.–“The Cruel Tribute,” James Baldwin
Which detail from the passage creates the most suspense for the reader?
“Minos, king of Crete, had made war upon Athens.” “He had laid waste the fields and gardens round about Athens.” “Then Aegeus, the king of Athens . . . went out to see King Minos and to treat with him.”
It is likely that the detail that creates the most suspense for the reader is "He [Minos] king of Crete, had made war upon Athens.”
What was the confrontation between Minos and Athenian ruler?
It is likely that the detail that creates the most suspense for the reader is "He [Minos] had sent word to the Athenian rulers that on the morrow he would march into their city with fire and sword and would slay all their young men and would pull down all their houses, even to the Temple of Athena, which stood on the great hill above the town."
This detail implies that the confrontation between Minos and the Athenian rulers will be violent and destructive, and the reader may be left wondering what will happen as a result. Additionally, the fact that Minos has already laid waste to the surrounding area and burned the merchant vessels in the harbor suggests that he is a formidable and potentially dangerous opponent, further increasing the suspense for the reader.
“Then Aegeus, the king of Athens . . . went out to see King Minos and to treat with him.”

Which of these would most likely happen if there is a sudden increase in the number of sunspots?A. summers would become colder B. Earth's tilt on its axis would decrease C. Earth's climate would become warmer D. length of days and nights would increase
Which of these would most likely happen if there is a sudden increase in the number of sunspots?
C. Earth's climate would become warmer
The correct answer is option C.
The sudden increase in sunspots will make the Earth more warmer because the more the sunspots, more energy is delivered to the atmosphere. This increases the global temperatures of the Earth.
The correct answer is C.
Sunspots increase and decrease through an average cycle of eleven years.
There is a debate of how much this sunspot would affect the earth`s temperature, the earth`s climate is sensitive to very weak changes in the Sun`s energy. During maximum sunspot activity, there`s a very slight increase in the energy output of the sun. Ultraviolet radiation increases during high sunspot activity, and this can have a large effect on Earth`s atmosphere.

14. Which of the following statements is/are correct? A. Most, if not all, members of Porifera are substrate feeders. B. Members of Porifera lack endoderm and ectoderm C. Sponges are a member of the phylum Cnidaria D. Sponges do not reproduce by sexual reproduction and instead only reproduce asexually. E. Given the following on the organism I. An animal II. Multicellular III. Lacks tissues IV. Lacks organs V. Asymmetrical This organism must be a member of the Phylum Porifera
Answer: Option E
Most of all poriferans/ sponges are suspension or filter feeders. Suspension feeders are organisms that each food materials which are suspended in their environment ie sea water, while filter feeders filter their food source from water by drawing water containing bacteria and organic matter in through their ostia(pores). Substrate feeders at organism that live in or on their food source.
Members of the poriferans do hava an ectoderm (epidermis) and an endoderm including a non-cellular late that is present in between the two layers.
No, they do not belong to the phylum cnidaria but porifera. Cnidarians including hydra, sex anemones, jellyfish etc and these have features that different from that of the sponges e.g the presence of nematocysts in cnidarians
Sponges can reproduce both sexually and asexually. Sexually by releasing larva fertilized in the sponge into water where they float around for some days and then proceed to adhere to a solid surface and begin their growth into adults. Asexually by budding
They are multicellular, lack tissues, are animals, lack organs and are asymmetrical. These are th distinguish features of poriferans
Answer: Option E.
Phylum porifera are group of organisms that live in aquatic habitats both marine and freshwater. They are diploblastic I.e they have two germ layers. They are assymetrical . They have round or vase-like or sac- like shape. They are multicellular and have bodies full of pores. They lack tissues and organs. Sponges are members of the phylum porifera.
