What are the sources of energy for the processes that affect Earth?

1 answer:

6 0

Answer: ok so Most of the energy in the Earth system comes from just a few sources: solar energy, gravity, radioactive decay, and the rotation of the Earth. Solar energy drives many surface processes such as winds, currents, the hydrologic cycle, and the overall climate system. Gravity makes rivers and other materials flow downhill and creates tides (from the Moon's gravitational pull). Radioactive decay creates heat in the Earth's interior, while Earth's rotational forces influence currents of air and water.

Use the Harris-Benedict equation to estimate your calorie needs. Show your calculations to explain how you arrived at your answe

Ratling [72]

Answer:

The Harris Benedict Equation is a formula that determines the total daily energy expenditure (calories) using BMR with some activity factors.

Basal Metabolic Rate (BMR) is defined as the amount of calories one would burn without doing anything for 24 hours. It uses variables of weight, age, height and gender to calculate BMR.

BMR calculation = 447.593 + (9.247 x weight in kg) + (3.098 x height in cm) - (4.330 x age in years)

In Harris Benedict Equation, BMR is multiplied by activity factor to determine calories need.

The activity factors in Harris Benedict Equation are:

for no exercise = 1.2

exercise for 1 to 3 days/week or light exercise = 1.375

exercise for 3-5 days/week or moderate exercise = 1.55

exercise for 6-7 days a week or hard exercise = 1.725

exercise for 2 times training = 1.9

So, calculation for my calorie needs is as following:

BMR = 447.593 + (9.247 x 50 kg) + (3.098 x 164.592 cm) - (4.330 x 23 in years) = 974.945

Calorie needs = BMR x 1.55

= 974.945 x 1.55

= 1511.16 calories

Describe what are the roles of producers, Consumers, and decomposers in an ecosystem?

Bumek [7]

Answer:

"How might different types of organisms--producers, consumers, decomposers--be important to a healthy ecosystem?" (Producers change energy into matter with chemical energy that other organisms can use and then consumers pass the matter and energy on to other organisms by eating and being eaten; decomposers recycle some ...

Which areas of the brain undergo major growth spurts during middle childhood?

djverab [1.8K]

sensory and motor areas undergo major growth spurts during middle childhood.

The two types of motor (movement) skills that children acquire are called "fine motor skills" and "gross motor skills."
Using hands and fingers to control smaller things is a function of fine motor abilities. coordination is a component of gross motor skills.
Synaptic remodeling, or pruning, is a natural process of maturation. Additionally, because each child has a different experience, the brain grows in large part as a result.
More often utilized synapses tend to be kept, whereas less frequently used synapses are lost.
The brain is driven by the motor system, which also drives sensory stimulation and feedback.
These abilities must advance and grow in order to support behavior and academic learning.
Children that struggle academically or behaviorally frequently have underdeveloped sensory and motor systems.

Which of the following statements about the light reactions of photosynthesis is true? a. There are two distinct photosystems, l

Natali5045456 [20]

Answer:

Option (A).

Explanation:

Photosynthesis may be defined as the process in which the light energy has been converted to the chemical energy so that plants can obtain their food with the help of sunlight, carbon dioxide and water.

Photosynthesis is divided into light reaction and dark reaction. The light reaction of photosynthesis is linked together by the mechanism which is similar to the electron transport chain of mitochondria.

Thus, the correct answer is option (A).
