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:

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

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

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.
