The net primary production of a pine forest on a lava flow on Mount Fuji is about 165,000 kcal/m2/yr, and the plant respiration

IceJOKER [234]

Answer:

The total amount of energy transferred during photosynthesis for this ecosystem equals 260,000 kcal/m2/yr.

Explanation:

To answer this question, we need to know that

gross primary productivity (GPP) = energy captured and converted into chemical energy during photosynthesis

net primary productivity (NPP) = difference between GPP and respiration rate

So, to calculate GPP we need to sum NPP to Respiration rate. This if,

NPP = 165,000 kcal/m2/yr

R = 95,000 kcal/m2/yr

NPP = GPP – Respiration

Then,

GPP = NPP + R

GPP = 165,000 kcal/m2/yr + 95,000 kcal/m2/yr

GPP = 260,000 kcal/m2/yr

Which level of maslow's hierarchy of needs is fulfilled by the nurse fitting a client who nearly died of asphyxiation with an ox

ICE Princess25 [194]

The correct answer is: first level.

Maslow's hierarchy of needs is a theory in psychology that is represented by hierarchical levels of human needs within a pyramid. There are five levels of needs:

1. Physiological (food, water, rest..),

2. Safety ,

3. love and belonging (friends, intimated relationships),

4. esteem (feeling of accomplishment),

5. self-actualization (achieving your own potentials).

If you found a vertebrate skull in the woods and the teeth were sharp and scissor-like, what type of food would you expect this

Zepler [3.9K]

The correct answer is: B) flesh of another animal

The shape of teeth is tightly connected with the food that animal eats.Examples:

• Herbivores (plant eaters) have flat teeth specialized for the grass chewing.

• Carnivores (flesh eaters) have long and sharp teeth for meat cutting.

• Omnivores (eat meat and plants) such as humans have various types of teeth with different functions.

There are four main types of teeth: incisors (at the front, sharp for cutting), canines ( to grip and tear food), premolars (flat surface for food crushing), molars (the biggest with flat biting surface, to chew).

In sheep, white is due to a dominant gene (W), black to its recessive allele (w). A white ewe mated to a white ram produces a bl

dedylja [7]

Answer:

Yes, 75%

Explanation:

Since the first offspring produced between the ram and the ewe was black you can determine that both sheep have a recessive and dominant allele. Both of the parent's genotypes would be Ww, this is because they both have the white phenotype and they were able to produce a black offspring. Since both parents have a genotype of Ww the probability of a black offspring being produced is 25% and 75% for a white lamb.

What is air pressure? How is it measured?

Volgvan

Atmospheric pressure is sometimes known as barometric pressure. Air pressure is exerted by the weight of air in the atmosphere of our planet Earth.
