Answer:
Phosphates and Sugars.
Explanation:
The strands are nucleotides and are connected by a pattern of phosphates and sugars.
Answer: Rosa's errors were options
A: Wind does not easily produce a lot of electricity.
C: Geothermal energy causes a lot wind pollution.
Explanation:
Wind Energy is the use of wind (kinetic energy) to provide mechanical energy and electricity through wind turbines. The wind turbines in a Wind farm ( made up of several wind turbines connected together) are then connected to electric power transmission network to generate electricity to households and grids.
Electricity is measured in Mega Watts (MW); Rosa is wrong because wind energy amounts for a significant percentage of electricity used in some developed worlds and mostly the European Union (EU) at a recorded 270 Giga Watts (GW). It is estimated that by 2020, wind energy will produce 50 percent of energy used by the EU.
Geothermal energy is the thermal energy (temperature of matter) which is gotten from energy generated and stored in the earth. Geothermal energy comes from radioactive decay of materials and the formation of earth.
Rosa is wrong, because Geothermal energy is environmental friendly and does not cause significant pollution. It does not involve fuel to harness its energy which in turn leads to stable electricity prices.
Answer:
The correct answer is: Two of the statements above are correct.
A cardiac muscle cell contracts spontaneously and is joined to other cardiac muscle cells by structures called intercalated discs.
Explanation:
Cardiomyocytes, the only ones responsible for the contractile function of the myocardium, are terminally differentiated cells that cease to proliferate almost immediately after birth. Cardiomyocytes are mononucleated cells, with the nucleus in a central position. These are linked together by the so-called intercalary discs, which appear as dark bands in histological preparations, and which are a set of junction complexes where desmosomes and adherent junctions can be found (here called fascia adherens). The intercalary discs are therefore the boundaries between cells.
There are four types of sensory receptors that respond to one of the four primary stimuli.
Thermoreceptors detect temperature changes in the environment.
Mechanoreceptors detect changes in pressure
Photoreceptors detect the photons composing light
Chemoreceptors detect chemical stimuli and are found inside the body (for example blood vessels). They are also responsible for our sense of taste and smell.
Thus, the correct answer to the question is D. on the tongue and in the nose, to detect taste or odor.
To ensure the continuity of the species
increase variation in species for natural selection to occur
