Look at the table for energy used in activities. Ella does 2 hours of dancing a week, plays football for 1 hour a week, and goes swimming for 0.5 hours a week. She has a mass of 55kg. How much extra energy will she need a week in order to do these activities?
Answers
Ella requires 3905 kJ of energy to do 2 hours of dancing a week, 1 hour of football a week, and 0.5 hours of swimming a week.
Ella, with a mass of 55 kg, does a series of activities in a week.
Let's calculate how much energy she needs for each activity in total.
DancingEllas does 2 hours of dancing a week, which consumes 18 kJ/kg.h.
2 h × 55 kg × 18 kJ/kg.h = 1980 kJ
FootballElla plays 1 hour of football a week, which consumes 25 kJ/kg.h.
1 h × 55 kg × 25 kJ/kg.h = 1375 kJ
SwimmingElla goes swimming for 0.5 hours a week, which consumes 20 kJ/kg.h.
0.5 h × 55 kg × 20 kJ/kg.h = 550 kJ
Total energy expenditureE = 1980 kJ + 1375 kJ + 550 kJ = 3905 kJ
Ella requires 3905 kJ of energy to do 2 hours of dancing a week, 1 hour of football a week, and 0.5 hours of swimming a week.

Which of the following statements is not true about heterotrophs?
Group of answer choices
Heterotrophs are classified as consumers.
Heterotrophs are at the base of most food webs.
Heterotrophs cannot make their own food.
Heterotrophs can consume autotrophs.
Answers
Heterotrophs are consumers, cannot make their own foods, and have some of them have the capacity to consume autotrophs. Hence, they are not at the base of most food webs.
Heterotrophs are organisms that have no capacity to manufacture their own foods, unlike autotrophs.
They depend on other organisms for their foods. Hence, they are known as consumers, unlike autotrophs that are called producers.
Heterotrophs are of different types:
Herbivores: those that consume autotrophs onlyCarnivores: those that consume meat onlyOmnivores: those that consume both autotrophs and meat.Thus, heterotrophs do not occupy the base of food webs. The base of food webs are mostly occupied by autotrophs, the producers.
More on heterotrophs can be found here: https://brainly.com/question/13420317?referrer=searchResults
Heterotrophs are at the base of most food webs is the statement that is false.
Heterotrophs are those that must consume organic matter from other living beings.Autotrophic beings represent the base in the totality of the trophic cycles or food chains, since they constitute the producing link, they are capable of taking advantage of energy and inorganic matter to make their food.Heterotrophs are characterized by not having the ability to produce their own food in their body, for this reason they need to consume the organic matter of other living beings.Therefore, we can conclude that autotrophs are considered producers and are at the base of most food webs, while heterotrophs are considered consumers which could not survive without feeding on other organisms.

In terms of structure and function how do the vacuoles in a typical plant cell compare to those of a typical animal cell
Answers
Answer:
Vacuoles in animal cells do NOT help the cell take its shape, however, in plant cells, vacuoles are larger, and DO affect the shape of the cell.
The function of the vacuole in plants is different from that in animals, as the vacuole in animals is smaller, while in plants it is larger and pushes the nucleus to one side while consisting of water and other materials.
What is the significance of the vacuole in plants and animals?Vacuoles are cell organelles found in both plants and animals, in plants, vacuoles are large, fluid-filled structures that occupy a large portion of the cell, and they perform several important functions, including storing water and helping to maintain the shape of the cell, while in animals, vacuoles are smaller and less in number than in plants, as they have a variety of functions, like storing waste materials, etc.

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).
