Answer:
Air inside the guard hairs traps heat close to the body, keeping the reindeer warm even in the frigid, windy temperatures of the tundra. The guard hairs also prevent body heat from escaping and melting the snow if the reindeer lies down, keeping it from getting wet and cold.
Answer:
multidimensional
Explanation:
Development is multidimensional
By multidimensionality, we mean a complex and dynamic interaction of factors that control development all through the lifespan, it as to do it biological, cognitive, and socioemotional changes.
Let's take for instance, in adolescence, puberty comprises of physiological and physical variations with variations in hormone levels, the formation of primary and secondary sex characteristics, changes in height and weight, and varying other bodily alterations. The cognitive changes (increment in thinking- abstractly), emotional and social changes (controlling emotions and relationships with equals, falling in love).
Puberty deals with a wide range of domains that exemplifies the multidimensionality component of development.
The correct answer is B. S-curve
Explanation
There are two models of population growth. One of them is the J-curve in which the population grows constantly without stabilizing, forming a J-shaped graph. Second, the S-curve is a model in which the population grows to a point, and from there it stabilizes, forming an S-shaped graph. According to the above, bacteria that divide rapidly until they run out of space and their growth slows down stabilizing the size of their population has an S curve model because the population does not grow unlimitedly but stabilized under specific circumstances. So, the correct answer is B. S-curve
Haploid cells are sex cells or gametes.
As electrons move along the chain, hydrogen ion are pumped from the stroma of the chloroplast into thylakoid lumen. these leads to creation of proton gradient in thylakoid lumen with the potential energy that will be used to synthesize ATP by enzyme ATPase in the process referred to as rotational catalysis. both chloroplast and mitochondria use electron transport chain to pump protons across the membrane and both enzyme ATPase to produce ATP using proton gradient created in the process of transport of hydrogen ions. the main existing between the electron transport chains of chloroplast and mitochondria is the initial source of energy. chloroplasts obtain their energy from sunlight whereas mitochondria obtain theirs from organic molecules.
