What type of food was discovered to make up the majority of the diet of human foragers (and, by extension, likely our ancient ancestors)

Answers

Plant foods such as nuts, fruits and roots was discovered to make up the majority of the diet of human foragers. Hominine ancestors depended on foraging.

Hominine ancestors (i.e., before the evolution of H. sapiens), depended on foraging for millions of years.

Foraging refers to the search for wild food resources, which are provided by nature by gathering different sources (e.g., plants, small animals, birds, insects, etc).

Nuts, fruits and roots represent excellent sources of food because they contain both macronutrients (lipids, proteins and carbohydrates) and micronutrients (i.e., minerals and vitamins).

explain the correlation between solar radiation and kelp biomass.

Answers

Given what we know, we can confirm that although sunlight is beneficial to plant growth, intense solar radiation has been proven to be detrimental to the survival of kelp, thus reducing its biomass.

How does solar radiation affect kelp?

Solar radiation is not harmful in very low amounts.

However, when exposed at long intervals or high intensity, it has been shown to cause tissue damage.

This tissue damage will inhibit the kelp's ability to undergo photosynthesis.

This means it will not be able to grow, and its biomass will be reduced.

Therefore, given the effect of solar radiation in damaging the kelp's ability to photosynthesize and thus reducing its growth, we can confirm that intense or prolonged exposure to solar radiation reduces kelp biomass.

On average, men have a basal metabolic rate (BMR) of 1.0 kilocalorie per kilogram per hour. Lawrence weighs 198 pounds. Calculate how much energy Lawrence expends for basal metabolism per day.

Answers

The energy Lawrence expends for basal metabolism per day is 2,160 kilocalories per day.

Basal metabolic rate is defined as the amount of energy that is used when an individual is at rest.

This energy is used for life sustaining functions such as:

breathing,

circulation,

nutrient processing and

cell production.

To calculate the Basal Metabolic Rate for Mr Lawrence,

Lawrence weight = 198 pounds

60

(convert pounds to kilogramme)

1 pound = 0.453592kg

198 pounds = x

xkg = 0.453592 × 198

= 89.8 kg

But BMR for average men = 1 kilocalorie per kilogram per hour.

That is, 1 kilocalories = 1 kg per hour

x kilocalories = 89.8 per day

Therefore for a day = 89.8 × 24 ( 24 hours = 1 day)

= 2155.469184

approximately. = 2,160kilocalories per day

A. The water is warmer than the land during the day.
B. Hurricanes that form in the oceans blow air into the shore.
C. During the day,solar radiation warms the land faster than the water.
D. Earth is tilted toward the Sun, causing air to move inland from the water​

Answers

If I am correct, the answer is supposed to be C due to on hotter portions of the day, land warms much faster than the water. This causes cooler air to rise from the oceans and the wind currents then push the air towards the land.

Answer: The NEGATIVE CONTROL is the

test tube that is filled with ONLY distilled

water.

Explanation:

A negative control of an experiment is

carried out alongside the main primary

experiment except that the treatment is

changed to something that is predicted

to have no result. In the negative

control, the student does not expect any

response. This would help the student

compare the result of a new experiment

against an already known existing results.

Analysing the experiment carried out

by the student, She filled two test tubes

with distilled water and placed a piece

of Elodea in one of the tubes, leaving

the other without a plant. The other test

tube that contains only distilled water is

the negative control because she wasn't

expecting any result from it. It's also

served as a control sample to the primary

experiment. This is observed as she

blew in each tube to add carbon dioxide,

which caused the distilled water to

become more acidic. This would help the

student know that the that experimental

results are valid and to ensure that time is
