The molecules that brings amino acids to the ribosomes are the tRNA molecules.
Explanation:
When a cell divides, it creates one copy of its genetic info within the type of DNA molecules for every of the 2 ensuing daughter cells.
The accuracy of those copies determines the health and hereditary options of the emerging cells and ribonucleic acid (tRNA) molecules carry amino acids to the ribosomes throughout macromolecule synthesis.
In organism cells, every category of RNA has its own enzyme, whereas in being cells, one RNA enzyme synthesizes the various category of RNA.
Answer:
The Chlorophyll
Explanation:
chlorophyll
At the first stage of photosynthesis, the light from the sun is absorbed in the light absorbing complex called the photosystem II in the thylakoid membrane. A molecule in the photosystem called chlorophyll P680 because of its absorption wavelength at 680 nm absorbs the light to commence photosynthesis.
Answer:
When light is absorbed by one of the pigments in photosystem II, energy is passed inward from pigment to pigment until it reaches the reaction center.
Explanation:
Answer: The correct answer is-
A. organs, but no true body cavity.
Based on the presence of body cavity ( also called coelom), multicellular animals can be classified as acoelomates ( no true body cavity), coelomates ( having true body cavity), pseudocoelomates ( false body cavity).
Roundworms are pseudocoelomic. This means that organs are present but the body cavity is not lined by mesodermal epithelium.
Body cavity is present between the external wall of body and the intestine and it baths the different body organs.
Thus, option A) is the right answer.
Answer:
Option A
Explanation:
All bilateral organisms have coelomates (cavity). However a Pseudocoelomate organism have a false cavity. By false cavity, we mean that there is a body cavity which is filled with fluid and all internal organs bathe in it including alimentary canal system , reproductive system etc. Unlike a coelom, Pseudocoelomate organism do not have body cavity completely lined with mesodermal cells.
hence, option A is correct
The given condition is termed as Infertility.
The infertility can be defined as the condition, in which the woman is not able to produce the young ones. This condition can be characterised by the absence of pregnancy, when no protection is used during intercourse or not able to stay pregnant. This condition can be a result of the fault in the reproductive system of the woman.
Can you give me the order of Biomes from coldest to hottest please? -desert -tropical savanna -tropical rain forest
-taiga
-temperate deciduous forest
-temperate grassland
-temperate woodland (chaparral)
Answer;
The order of the Biomes from the coldest to the hottest
-tundra ; It is the coldest of all the biomes
-taiga ; It is a land dominated by conifers, especially spruces and firs. It is dotted with lakes, bogs, and marshes.
-temperate deciduous forest ; The average rainfall is 30 to 60 inches a year.
-temperate grassland ;The annual precipitation in the grasslands averages 20 inches (~51 cm) per year.
-temperate woodland (chaparral) ; The annual rainfall in the chaparral biome may reach 20–30 inches (64–76 cm)
Savanna; also known as the tropical grass land; the average temperatures are about -20°C to 30°C
-tropical rain forest;An annual rainfall of as much as 150 inches (381 cm) produces a lush forest of conifers.
-desert ; Annual rainfall in the desert is less than 10 inches (25 cm) and, in some years, may be zero.
The order of biomes from coldest to hottest is: Tundra, Taiga, Temperate deciduous forest, Temperate grassland, Temperate woodland (chaparral), Desert, Tropical savanna, Tropical rainforest.
The order of biomes from coldest to hottest is as follows:
The tundra biome is the coldest, with long, extremely cold winters and short cool summers. The taiga (boreal forest) biome is characterized by long, cold winters and short, cool summers. The temperate deciduous forest has a moderate climate with four distinct seasons. The temperate grassland has hot summers and cold winters. The temperate woodland (chaparral) is characterized by mild, wet winters and hot, dry summers. The desert biome has extremely hot and dry conditions. The tropical savanna biome has a hot climate with distinct wet and dry seasons. The tropical rainforest biome is the hottest, with high humidity and heavy rainfall.
