You recently identified a molecule that you believe is a primary messenger for a signal transduction mechanism. All you know about this ligand is that it is hydrophilic. Where would you expect to find initial interaction of the molecule with its receptor
Answer:
Receptor on the outer cell surface.
Explanation:
Hydrophilic signal molecules are the water soluble molecules, they are polar polar and therefore cannot pass through the non-polar center of the plasma membrane without any mediator. Water-soluble ligands bind to the extracellular domain of cell surface receptors. Signal molecules cannot enter the cell and thus plasma membrane receptor is required. Plasma membrane receptor form an important class of integral membrane proteins that transmit signals from the extracellular space into the cytoplasm. This group of signal molecules is quite diverse and most are based on amino acids. In some cases the unmodified amino acid is the signal molecule, in others the amino acid is modified into a derivative and in still others amino acids are combined into peptides and proteins.
What is the correct order of blood flow from the heart to the lungs in the fetal circulatory system? a. Ductus venosus, heart, vena cava, ductus arteriosus, arteries b. Vena cava, ductus venosus, heart, ductus arteriosus, arteries c. Ductus venosus, vena cava, heart, ductus arteriosus, arteries d. Vena cava, heart, ductus venosus, ductus arteriosus, arteries
Answer:
When the blood enters the right atrium, most of it flows through the foramen ovale into the left atrium. Blood then passes into the left ventricle (lower chamber of the heart) and then to the aorta, (the large artery coming from the heart).
Explanation:
Answer:c.
Ductus venosus, vena cava, heart, ductus arteriosus, arteries
Explanation:
The circulatory system consists of the heart and blood vessels. In a fetus, the circulation of blood is different from circulation after delivery largely due to the fact that the lungs are not in use, rather, the fetus obtains oxygen and nutrients from the mother through the placenta and the umbilical cord.
Blood from the placenta is carried to the fetus by the umbilical vein. While some of this blood enters the fetal ductus venosus and is carried to the inferior vena cava, some others enter the liver. The blood from the inferior vena cava then moves into the right atrium of the heart. The foramen ovale, an opening between the right and left atrium in the fetus directs most of the blood flow from the right into the left atrium, thereby, bypassing pulmonary circulation. Most of the blood from the right atrium flows into the left ventricle and is pumped through the aorta to the rest of the body.
Some of the blood from the right atrium however, enters into the right ventricle and is pumped into the pulmonary artery. The ductus arteriosus which is a special connection between the pulmonary artery and the aorta in a fetus, directs most of this blood away from the lungs and into the arteries.
_______on the blood determine a person’s blood type. _______in the blood attack foreign blood not compatible with the antigens on the blood.
Answer:
the first one is Antigens and the second one is Antibodies
Explanation:
Antigen is usually present on the blood that determine the person’s blood type. While antibodies in the blood attack foreign blood not compatible with the antigens on the blood.
What are antigens?Blood group antigens seem to be either sugars or proteins that bind to various components of the red blood cell membrane. The antigens of the ABO blood group, for example, are sugars.
Whereas antibodies are present in the blood that determines certain antigens present in the blood that are non compatible.
Thus, the answer for blank 1 is antigen, and for blank 2 is antibody.

¿Podrá la planta producir frutos dentro de una caja oscura?
Answer:
No.
Explicación:
No, la planta no podrá dar fruto en una caja oscura porque para su crecimiento la planta necesita luz solar y sin luz solar no se produce fotosíntesis y sabemos que en el proceso de fotosíntesis, las plantas preparan su propia comida y crecen en tamaño. Este proceso de fotosíntesis solo ocurre en presencia de luz solar, por lo que en la oscuridad no hay luz solar, por lo que no se produce la fotosíntesis y la planta morirá.

A tropical rainforest includes trees, animals, insects, plants, rain, rivers, rocks, soil, and warm, moist air. Which spheres of Earth are represented in a tropical rainforest?
Answer:
spheres of Earth are represented in a tropical rainforest are
1. BIOSPHERE
2. HYDROSPHERE
3. LITHOSPHERE
4. atmosphere
Explanation:
Biosphere :The biosphere includes all life on Earth - plants, animals and humans. Most of what is studied in Life and Living is about the biosphere. The biosphere also includes life in the oceans, and under the soil. For example bacteria living on decaying plant material and the smallest sea creatures and plants are part of the biosphere.
Hydrosphere: The hydrosphere includes all water on the planet - the oceans, lakes, rivers, groundwater, rain, clouds, glaciers and ice caps. About 70% of the surface of the Earth is covered with water. The oceans contain most of this water, with only a small portion of it being fresh water. All the water on Earth forms part of the hydrosphere.
Atmosphere:The atmosphere includes all the air above the surface of the Earth all the way to space. All the gases that are present in the air are included in the atmosphere. Most of the atmosphere is found close to the surface of the Earth where the air is most dense. The air contains 79% nitrogen, less than 21% oxygen, and a small amount of carbon dioxide and other gases
Lithosphere: The lithosphere includes the Earth's crust and the upper part of the mantle. All mountains, rocks, soil and minerals included in the Earth's crust are part of the lithosphere. Even the seafloor is part of the lithosphere, because it is also made up of sediments of sand and rock.

1. Which of the following is NOT a result of convection current? a) The air in a room is cooled by an air conditioner b) Wind blows towards the beach from the sea. c) The water in a kettle is heated and boils d) The wax covering an iron rod melts when the rod is heated.
Answer:
its D
Explanation:
because conduction happens through solids and the others are obviously conventional current
The wax covering an iron rod melts when the rod is heated ( D ) is not a result of convection current
Convection is the transfer of heat energy from an area of higher concentration to an area of lower concentration and it occurs in fluids and gases. while conduction is the transfer of heat energy from one object to another through the direct contact of the objects and this occurs between solids.
The transfer of heat from the heated rod to the wax covering occurs because of the direct contact the wax has with the heated rod therefore it is conduction and not a convection current.
Hence we can conclude that The wax covering an iron rod melts when the rod is heated is not a result of convection current

D. Complex I, Ubiquinone, Complex III, Cytochrome C, Complex IV, Oxygen.
Flow of electrons in ETC:In the mitochondrial ETC, electrons flow when the reduced electron (NADH, FADH₂) are oxidized. In plants and other photosynthetic organisms, an ETC serves to oxidize NADPH. They travel down the electron transport chain, releasing the electrons that they once had. The end result is loads of energy, approximately 34 ATP (energy molecule).
Thus, the track of flow will be: Complex I, Ubiquinone, Complex III, Cytochrome C, Complex IV, Oxygen

Describe the process, development of Male gametophyte in flowering plants ?
Explanation:
The male gametophyte containing the generative cell splits into two sperm nuclei, one of which fuses with the egg, while the other degenerates. After fertilization of the egg, the diploid zygote is formed, which divides by mitosis to form the embryo. The scales of the cones are closed during development of the seed
Answer:
Androecium:
Androecium is the third whorl, which is the male reproductive part of the flower.
Unit:
Its units are called stamen.
Stamen:
Each stamen has a thread like filament at the free end of which anther is attached.
Anther:
Anther has pollen sacs in which haploid microspores (pollen grains) are produced through meiosis.
Process:
Each microspore germinates into the male gametophyte generation. During it, the nucleus of microspore undergoes mitosis ans produces two nuclei i.e. a tube nucleus and a generative nucleus. The generative nucleus again undergoes mitosis and produces two sperms. So, a germinated microspore has a tube nucleus and two sperms. All these structures are the male gametophyte generation of the plant.

What phase of mitosis is shown in the diagram below?
O A. Prophase
O B. Telophase
O C. Metaphase
O D. Anaphase
Answer:
B. "Telophase"
Explanation:
The chromosomes are at opposite poles, the nuclear envelope is reforming and the cell is getting ready to divide, the next phase is Cytokinesis.
Hope this helped.
Telophase is a phase of mitosis as shown in the diagram below. The correct option is (B).
Telophase is a stage of mitosis, the procedure by which eukaryotic cells divide. The splitting of the cytoplasm into two daughter cells during cytokinesis, the last stage of mitosis, follows it.
There are several significant events that occur during telophase:
Chromosome decondensation: The chromosomes that were tightly curled and compressed during metaphase and anaphase begin to uncoil. As a result, the genetic material is able to spread and become less obvious under a microscope.
Nuclear envelope formation: Around the divided sets of chromosomes, the nuclear envelope, which had fragmented during prophase and metaphase, starts to reconstruct.
Hence, telophase is a phase of mitosis as shown in the diagram below. The correct option is (B).
