Seedless plants genetically alternate between generations.

<h3>What is the reproduction cycle of seedless plants like?</h3>

All seedless vascular plants have very similar life cycles. As in bryophytes, their life cycle has two alternating generations:

  • the gametophyte
  • and the sporophyte.
  • The sporophyte is always the dominant and free-living generation.

With this information, we can conclude that seedless plants genetically alternate between generations.

The Q are 1. Emma is a 26-year-old professional woman who maintains her weight at 140 pounds by following a lacto-ovo vegetarian
bearhunter [10]

Answer:

Question 1

a) What is Emma’s recommended daily protein requirement? 50.4 grams

b. What percentage of Emma’s current total energy intake comes from protein?

13.33%

Does it fall within the recommended range in terms of the percentage of total energy intake?

Yes it does fall within the recommended range in terms of the percentage of total energy intake which is 10 - 35%

c. Emma is concerned about her intake of the essential fatty acid omega-3. Can you suggest for her two food items that she can include in her diet?

i. Walnuts

ii. Flaxseeds.

Question 2

2. Rank the following oils/fats according to the ease with which they would spoil, and explain how you arrived at your conclusion: coconut oil, flaxseed oil, olive oil.

According to the ease of spoilage:

Flaxseed oil – Coconut oil – Olive oil

Explanation:

a) What is Emma’s recommended daily protein requirement?

RDA of protein for adults is given as 0.8 g per kilogram of body weight of 0.36 per pounds of body weight.

Therefore, Emma's recommended daily protein intake is calculated as:

Her body weight in pounds × 0.36

Emma's body weight = 140 pounds

140 pounds × 0.36

= 50.4 grams.

Therefore, Emma’s recommended daily protein requirement is 50.4 grams of protein.

b. What percentage of Emma’s current total energy intake comes from protein?

Since 4 calories is the energy received from 1 gram of protein

In the question, we are told that Emma takes a daily intake of 40 grams of protein.

Therefore,

1 gram of protein = 4 calories

40 grams of protein =

40 × 4 = 160 calories.

The Lacto Ovo vegeterian diet, Emma is on gives her 1200 calories per day.

Hence, the percentage of Emma’s current total energy intake comes from protein is calculated as:

(Emma's daily energy in calories from protein ÷ Daily energy in calories supplied by her Lacto ovo vegetarian diet) × 100

= (160 calories ÷ 1200 calories) × 100

= 13.33%

c.

Omega -3- fatty acids are fatty acids that are very good for the body. Even though they are fatty acids, they do not clog the arteries thereby helping in preventing the occurrence of heart disease. They also lower the blood pressure in the body.

Foods that contain omega -3- fatty acids are fatty fish such as Salmon, Mackerel as well as nuts and seed like Walnuts, Flax seeds ( Flax seed oil).

Emma is concerned about her intake of the essential fatty acid omega-3. Can you suggest for her two food items that she can include in her diet?

Since Emma takes nuts, 2 food items she can include in her diet that are rich in Omega-3 fatty acids are:

i. Walnuts

ii. Flax seeds

2. Rank the following oils/fats according to the ease with which they would spoil, and explain how you arrived at your conclusion: coconut oil, flaxseed oil, olive oil.

According to the ease of spoilage:

Flaxseed oil – Coconut oil – Olive oil

Flaxseed oil spoils more easily than coconut oil and coconut oil spoils easily than Olive oil. This is based on their exposure to heat.

When heated up, Flaxseed oil breakdown more easily , followed by coconut oil.

Coconut oil has the tendency to become cloudy after been stored for a while.

This is why even though we can use but Flaxseed and Coconut oil for cooking , Olive oil is still the best because it has the tendency to withstand a large amount of heat and it is heat stable as well as more stable at even room temperature.
