Answer:
»Some of the uses of surface tension :-
1) Surface tension allows insects (e.g. water striders), usually denser than water, to float and slide on a water surface.
2) Surface tension is an important factor in the phenomenon of capillarity.
3) Surface tension has the dimension of force per unit length, or of energy per unit area.

Which statement regarding the structure or function of ribosomes is correct?
a. In eukaryotes, the ribosomes found in chloroplasts and mitochondria are 70S ribosomes, which are similar in size to prokaryotic ribosomes.
b. Ribosomes are found both free-floating and attached to the rough endoplasmic reticulum in eukaryotes and in prokaryotes.
c. Ribosomes are the sites of lipid biosynthesis in both prokaryotes and eukaryotes.
d. The ribosomes in the prokaryote are slightly larger than those found in the eukaryotic endoplasmic reticulum.
Answer:
C
Explanation:
Ribosomes are in Eukaryotic and Prokaryotic cells
I think this is correct
Ribosomes are the site for the protein synthesis. In eukaryotes, the ribosomes found in chloroplasts and mitochondria are 70 S ribosomes, which are similar in size to prokaryotic ribosomes. The correct answer is option a.
What is RER and SER ?It is the rough endoplasmic reticulum and the smooth endoplasmic reticulum.
Eukaryotes and the prokaryotes both got the DNA and the ribosomes as well. The ribosomes which are present in eukaryotes are 80 S and the prokaryotes have 70 S type of ribosome units thus the Mitochondria along with the chloroplast in the prokaryotes have their own ribsomes as well as DNA which is 70 S that is same to the prokaryotes.
Endoplasmic reticulum is the site of lipid synthesis and with that they do show the association with ribosomes for the protein synthesis but not in prokaryotes but that happens in the eukaryotes.

In the inheritance pattern incomplete dominance offspring demonstrate an intermediate form of alleles from the parents. Is it true or false science
Answer:
The correct answer is True
Explanation:
Incomplete dominance occurs when the dominant allele is not completely expressed to the total exclusion of the recessive allele hence the Phenotype/physical appearance shows an intermediate between the dominant and recessive alleles of the gene. An example of incomplete dominance is when a red flower is cross-pollinated with a white flower and a pink flower is produced as offspring (instead of a red or even white offspring).

Identify the living and non-living parts of the nitrogen cycle.
The nitrogen cycle is a cyclical process in which nitrogen moves through both living and non-living things, including the atmosphere, soil, water, plants, animals, and bacteria.
What is nitrogen cycle?The Nitrogen Cycle is a biogeochemical process in which nitrogen is converted into various forms before passing from the atmosphere to the soil to the organism and back into the atmosphere.
Nitrogen fixation, nitrification, denitrification, decay, and putrefaction are some of the processes involved.
Nitrogen fixation, nitrification, and denitrification are the three major steps in the nitrogen cycle.
It is a biosphere cycle that includes the atmosphere, hydrosphere, and lithosphere. Nitrogen can be found in a variety of reservoirs.
The nitrogen cycle is a cyclical methodology in which nitrogen moves through both living and nonliving systems such as the atmosphere, soil, water, plants, animals, as well as bacteria.
Thus, these are some living and non-living parts of nitrogen cycle.

Distinguish between catabolism and anabolism, giving an example of each reaction as endergonic or exergonic:
Answer: Anabolism builds complex molecules from simpler ones, while catabolism breaks large molecules into smaller ones.
Explanation:
a-Glycerol reacts with fatty acids to make lipids:
CH2OHCH(OH)CH2OH + C17H35COOH → CH2OHCH(OH)CH2OOCC17H35
Simple sugars combine to form disaccharides and water:
C6H12O6 + C6H12O6 → C12H22O11 + H2O
c-During cellular respiration, glucose and oxygen react to yield carbon dioxide and water
C6H12O6 + 6O2 → 6CO2 + 6H2O
In cells, hydroxide peroxide decomposes into water and oxygen:
2H2O2 → 2H2O + O2

Answer:
1. THE DESERTS -DEFINITION. -FEATURES. -BIOTIC AND ABIOTIC FACTORS THAT INFLUENCE DESERT BIOME. -MOST REPRESENTATIVE DESIERTS IN OUR PERU. DELGADO ENVIRONMENT ELERA, REYNER San José de Moro, September 2014
2. DESERT A desert is an area of the earth's surface totally or almost totally uninhabited. A desert can be a sandy or stony terrain that lacks vegetation due to low rainfall. The harsh environmental conditions mean that these deserts have little stable population DELGADO ELERA, REYNER. CHARACTERISTICS OF THE DESERTS. Temperatures are generally high, but nights can be cold. Its climate is extreme with temperatures of 50 ° C during the day and –20 ° C at night. It is the ecosystem that presents water scarcity. The ground is covered with sand as a result of the disintegration of rocks. The relief presents plains, dunes and in some places oases. There are counter winds and rains are very scarce. Deserts form the largest area of the earth's surface. BIOTIC AND ABIOTIC FACTORS THAT INFLUENCE DESERT BIOMA BIOTIC FACTORS THAT INFLUENCE DESERT BIOME These are the living beings of an ecosystem that survive. They can refer to the flora, fauna, humans of a place and their interactions. Individuals must have specific behavior and physiological characteristics that allow their survival and reproduction in a defined environment. The condition of sharing an environment engenders a competition between species, given by food, space, etc. Depending on the region: In the desert only some animals manage to survive: camels, lizards, spiders, owls, rats, kangaroo, mice, a variety of snakes, hawks, scorpions, birds, squirrels among others. In the same way, in the fauna, only some plants manage to survive. These protect themselves from other animals with the thorns they have and with their thick layer of skin, some of them are: cactus, palm trees, nopales, bushes, grasslands, weeds in oases, etc.
3. Plants and animals that live in the desert are conditioned to withstand extreme temperatures with minimal water. ABIOTIC FACTORS THAT INFLUENCE DESERT BIOME Abiotic means lifeless. They are the different components that determine the physical space in which living beings inhabit; among the most important we can find water, temperature, light, soil, humidity, air and nutrients. They are the lifeless factors. Deserts are known for their extreme abiotic factors. Varied temperature and scarce fluvial precipitation. Sunlight, climatic factors such as: humidity (very low) and temperature (high during the day, very low at night); rocks, sand or very dry soil, atmospheric gases, very strong barometric pressure. Rocky terrain, wind processes are important factors in the formation of the landscape. They have an average rainfall of 200 to 500 mm per year. MOST REPRESENTATIVE DESERTS OF PERU 1. DESERT OF SECHURA One of the most representative deserts of Peru is that of Sechura, located in the northwest of Peru, just between the Lambayeque and Piura regions having a length of 150 kilometers by a width of 100. It is located 55 km southwest of the city of Piura. It is the widest area of the coastal desert in Peru, it has an area of more than 5000 square km. This desert is an arid plateau formed by materials from the Tertiary, with little vegetation, which includes several intermittent lagoons. The aridity of the climate and the unproductive soils limit the settlement of the population, except in the oases that constitute the mouths of the Piura rivers, to the north, and Lambayeque, to the south; agriculture is possible in these areas.
