Andreas93 [3]

Answer:

True

Explanation:

The Modern Synthesis is also called the Neo-Darwinian theory as it explains the fusion of Mendelian genetics with Darwinian evolution into a singular theory of evolution. It is sometimes referred to as the Neo-Darwinian theory.

It refers to evolution as "changes in allele frequencies within populations," in order to explain the genetic basis of evolution. The random genetic drift, gene flow, mutation pressure, and natural selection are seen to cause changes in allele frequencies. Resulting in several differences that can be seen gradually over a particular period in time.

In the Modern Synthesis, mechanisms of evolution and not natural selection takes a major role and it explains the continuance of genetic variation going along with Gregor Mendel's particulate theory of inheritance, where the alleles of a gene remain as individual entities rather than merging.

The major key players of the Modern Synthesis are R. A. Fisher and Sewall Wright (worked on population genetics), Theodosius Dobzhansky (studied the fruitfly Drosophila), Ernst Mayr (models of how speciation occurs), George Gaylord Simpson (introduced paleontological observations into Modern Synthesis) and G. Ledyard Stebbins (added some principles as a result of his botanical studies).

The pollination of a tomato flower by honeybees best illustrates

Lady_Fox [76]

Answer:

it best illustrates mutualism which is defined as a relationship that benefits two organisms, or it is defined as a doctrine in sociology where mutual aid is beneficial to society and the individual. An example of mutualism is pollination which is when bees take nectar from flowers and then deposit the nectar on another flower. I hope dis helps :3

Bob, a nutritionist who works for the university medical center, has been asked to prepare special diets for two patients, susan

abruzzese [7]

Answer and Explanation:

Possibly, you forgot to attach the table with the contents of each food. Therefore, I calculated the task with similar values.

1. Assume you have Food A, B, and C. Each has certain amount of Calcium, Iron, and Vit C.

Let's designate: Calcium → X oz , Iron → Y oz, vit C → Z oz

2. Assume you have following amount of Calcium in each food:

Food A = 30 mg/oz
Food B = 25 mg/oz
Food C = 20 mg/oz

3. Assume you have following amount of Iron in each food:

Food A = 1 mg/oz
Food B = 1 mg/oz
Food C = 2 mg/oz

4. Assume you have following amount of vit C in each food:

Food A = 2 mg/oz
Food B = 5 mg/oz
Food C = 4 mg/oz

Calculations:

→ You have 3 different food and each has Calcium in it. You need exactly 320mg of Calcium per day. Therefore, each food would comprise certain proportion of daily Calcium intake. We can come up with equation: 30X+25Y+20Z = 390 mg

Similarly, for iron and vitamin C, the next equations could be used:

X+Y+2Z=17 - Iron

2X+5Y+4Z=42 - Vit C

→ Now you have a system of equations:

30X+25Y+20Z = 390 (1)

X+Y+2Z=17 (2)

2X+5Y+4Z=42 (3)

→ Look for similarities! (1) and (3) seem to be similar. We can multiply the (3) by -5 to obtain: -10X-25Y-20Z=-210. We add the (1) and modified (3) equations.

30X+25Y+20Z = 390

-10X-25Y-20Z=-210

__________________

20X+0+0=180

20X=180

→ X=9 (oz of Calcium)

→ Now, we can put x=9 into equations above to ease our job:

270+25Y+20Z=390 → 25Y+20Z=390-270=120

9+Y+Z=17 → Y+2Z=17-9=8

18+5Y+4Z=42 → 5Y+4Z=42-18=24

→ Similarly, we can use Eq-s (2) and (3). We can multiply the (2) by -5 to obtain: -5Y-10Z=-40. We add the (3) and modified (2) equations.

-5Y-10Z=-40

5Y+4Z=24

__________________

-6Z=-24

Z=4

→ Z=4 (oz of vit C)

→ Now, we can take X+Y+Z=17 (2) and just put in known values(X=9 and Z=4) to obtain Y:

9+Y+4=17

→ Y=17-9-4=4 (oz of Iron)

That's all! So, if you have table values, you can just re-write the equations and doing it stepwise, as it is shown here, you can manage to calculate every value you need :)
