Answer:
The average conversion energy from producers to primary consumers is b. 10%.
Explanation:
This percentage actually holds true for all transfer of energy at any trophic level in the food chain. Majority of the energy loss can be attributed to metabolic processes that give off heat and other forms of energy. It is important to note that energy cannot be created nor destroyed, it is simply transformed from one form to another.
<span>Three months after fertilization and development of a placenta around the developing fetus, the corpus luteum regresses and forms the corpus albicans.</span> Formed placenta takes over progesterone production (which was the role of corpus luteum) and the corpus luteum degrades into a corpus albicans. The corpus luteum is being broken down by macrophages, in a process called luteolysis. The remains of the corpus albicans may persist as a scar on the ovary.
Answer:
1500
Explanation:
Let's assume that the allele for yellow seed color is "Y" and the allele for green seed color is "y". Genotype of pure breeding yellow seeded plant would be "YY" and that of the green seeded plant would be "yy". A cross between YY and yy gives all heterozygous yellow seeded plants (Yy) in F1 progeny. Self pollination of two F1 plants (Yy x Yy) obtains F2 generation in 3 yellow: 1 green ratio.
The total population size of F2 generation = 2000
The proportion of yellow seeded plants in F2 generation = 3/4 (since the F2 phenotype ratio is given 3 yellow: 1 green)
Therefore, total number of yellow seeded plants in F2 progeny = 3/4 x 2000= 1500
Answer:
5. false 9 percent make up agriculture
6. false the population would be 9.8 billion
7. the current population on earth is 7.7 billion or rounded up is 7 billion
8. 40 percent of earth surface is used for agriculture.
9.The UN Food and Agriculture Organization says one-third of all food is wasted.
10. eating for a healthy planet means eating sustainably. The meaning means what you eat may need to be sustainable because it can be regrown and not be cut off. Also it could mean what you eat wont leave a footprint on the earth.
