Grana, thykaloids and storma are components found in the chloroplast within plant cells
The correct answer is option D, that is, phenotypic.
The composite of an organism's observable traits or features, like its development, morphology, physiological or biochemical characteristics, products, and behaviors of an organism is known as a phenotype.
A phenotype is an outcome of the expression of the genetic code of an organism, its genotype, and the effect of environmental elements and the associations between both. The error in transcription or translation process usually leads to physical or phenotypic modifications in an organism.
Answer:
Temperatures in a desert climate range from 86 to 104 degrees Fahrenheit, while summers are wet and winters are dry. When the rains fall, herds of prey animals abound as they feed on the lush grasslands and water at the many waterholes and rivers. The average rainfall in the desert is 10 inches per year. Sahara desert vegetation includes African Welwitchsia, date palm, thyme, magaria, olive trees, orange trees, and fig trees. Apart from these, more than half of the Sahara desert is extremely barren with no vegetation found. However, there are still some areas in the Sahara desert that are lush, containing abundant trees and plants. The most common landscape features found in deserts are sand dunes, yardangs, desert pavements, debris, playas, oases, mesas, alluvial fans, arroyos and buttes. These landforms vary from desert to desert. In areas dominated by the tundra climate type, winters are long and cold, especially in the region north of the Artic Circle where, for at least one day in the year, the Sun does not rise. Winter precipitation generally consists of dry snow, with seasonal totals less than in the summer when cyclonic storms that develop along the boundary between the open ocean and sea ice yield rainfall. The average snowfall in the tundra is 10-40 inches per year. Tundra vegetation is composed of dwarf shrubs, sedges and grasses, mosses, and lichens. Scattered trees grow in some tundra regions. The ecotone between the tundra and the forest is known as the tree line or timberline. The arctic tundras located between the north pole and the coniferous forests or taigaregion. It is characterized by extremely cold temperatures and land that remains frozen year-round. Arctic tundra occurs in frigid mountaintop regions at very high elevations.
1. C. prey-predator
2. A. competition between lizards and frogs for food
Answer:
The correct answer would be D. The central nervous system processes stimuli information the body receives, and the peripheral nervous system senses stimuli and carries out the reaction.
Nervous system is made up of highly specialized cells termed as neurons or nerve fibre which are capable of detecting, receiving, and transmitting different kind of stimuli.
It can majorly divide into:
Central nervous system (CNS): It consists of brain and spinal chord which are the information processing and controlling center of the body.
Peripheral nervous system (PNS): It consists of the all the nerves of the body associated with central nervous system. It is composed of two types of nerve fibres: afferent nerves (sense stimuli and carry impulses from tissues to the CNS) and efferent nerves (carry regulatory impulses from CNS to the target tissues).
