Any ideas?

I'll choose Golden Retrievers:

These dogs where created for duck-hunters. Their purpose was to go catch the ducks that fell on the lake/river once they were shot by the hunter - here we see how they serve (or actually served) men.

Nowadays, Golden Retrievers are known to like water a lot, and to be very playful with it - and here is where we see a genetic adaptation. They needed to be in water, and were modified to like it.

Hope it helped,

Anna tries to keep her kilocalorie intake under control. She eats mostly lean meats or fish and a lot of vegetables. Yesterday,
n200080 [17]

Answer:

The calories Anna consumed for dinner is 315 kcal (300kcal). The calories that came from proteins is 108 kcal (100kcal).

Explanation:

Macronutrients are nutrients such as protein, carbohydrates, and fat that provide the energy required for the normal functioning of the body. Usually, the energy obtained from macronutrients is expressed in calories. Each gram of protein provides 4 kilocalories while each gram of fat provides 9 kilocalories. Carbohydrates per gram also provide 4 kilocalories.

Here, Anna consumed  7 grams of fat (in salmon)

, 36 grams of carbohydrates (in sweet potatoes and asparagus)  and 27 grams of protein (in salmon, sweet potatoes, and asparagus) for the dinner.

Therefore, total calories in 7 grams of fat is 7*9=63 kilocalories.

Total calories in 36 grams of carbohydrates is 36*4=144 kilocalories.

Total calories in 27 grams of protein is 27*4=108 kilocalories.

Therefore, the total calories Anna consumed for dinner is 63+144+108=315 kilocalories i.e., 300 kcal.

The calories that came from proteins is 108 calories  i.e., 100 kcal.

GMOs may lead to the use of different herbicides or pesticides.<br> True or False?
Dafna11 [192]

GMOs may lead to the use of different herbicides or pesticides is a true statement.

Explanation:

The GMO crops leads to growth of weeds that can resist herbicides other than for which the GMO is genetically-modified. The over-usage or over-reliance on herbicide-resistant GMO (Genetically modified organisms) crops had given way to the growth of such superweeds.

The main characteristic of these superweeds is resistance to the herbicides or the weedkillers leading to infestation of farmlands by these superweeds Hence farmers need to add different herbicides or pesticides to control the growth of superweeds.
