The correct answer to your question Andresgrajeda60 is choice D
Speed of sound in water = 1500 m/s
frequency = 20Hz
wavelength = s/f = 1500/20 = 75m
<h2>A) option is correct </h2>
Explanation:
Skin has two types of sweat glands: eccrine and apocrine
Eccrine glands occur over most of the body and open directly onto the surface of skin whereas apocrine glands open into the hair follicle, leading to the surface of the skin and develop in areas abundant in hair follicles, such as on scalp, armpits and groin
The eccrine gland is controlled by the sympathetic nervous system and regulates body temperature
In some animals, when internal temperature rises the eccrine glands secrete water to the skin surface, where heat is removed by evaporation
Eccrine glands when active are considered major thermoregulatory devices
Smaller mammals, such as rodents, cannot endure dehydration and hence possess no eccrine glands at all
The addition of dynactin caused dynein to travel farther along the micro tubule.
<u>Explanation:</u>
Dynein is a family of cytoskeletal motor proteins that move along micro tubules in cells. They convert the chemical energy stored in ATP to mechanical work. Dynein transports various cellular cargo, provides forces and displacements important in mitosis, and drives the beat of eukaryotic cilia and flagella.
Dynactin is a 23 sub unit protein complex that acts as a co-factor for the micro tubule motor cytoplasmic dynein-1. It is built around a short filament of actin related protein-1.
The sun gives off _solar___energy, which enters the atmosphere. Plants absorb some of the energy and perform photosynthesis to convert it into_chemical__energy in the form of sugars. Plants and the animals that eat them then turn that energy into a different form of _chemical___
energy, in the form of ATP. When plants and animals use the energy, it becomes _heat_ energy.
The energy producing process for life starts with the use of solar energy by plants in photosynthesis. Green plants takes up solar energy from the sun and uses it to manufacture sugar and oxygen gas in the presence of carbon dioxide and water. The sugar stores chemical energy.
When the food produced by plant is eaten, during cellular respiration, the ATP formed from break down of the food is used to liberate heat energy. The bond between the second phosphate element is broken down and heat energy is released from the stored chemical energy.
This gives off carbon dioxide and water as the by product.
