Which of the following is not true of energy in a cell?
The cell must have energy to maintain homeostasis.
O Energy can be created by the cell.
O The cell uses mostly chemical energy.
O Energy can be converted by the cell.
Answers
Answer:
I think is the top one A hope this helps
Cells have a different function it can convert chemical energy to another form of energy to maintain homeostasis, and cells cannot create energy only change the form of energy, hence option b is correct.
What is the energy of the cell?Every cell must continue to check its levels of energy and adjust ATP production rates in line with metabolic demand in order to keep homeostasis.
The ability of cells to sense, and convert nutrients into chemical energy is essential for the continuous fulfillment of this energy demand.
To drive metabolic reactions that would not happen automatically, to transfer necessary substances across membranes, and to do mechanical work, such as moving muscles, cells need chemical energy.
Therefore cells use energy to maintain homeostasis and can change one form of energy into another but can not create energy, hence option b is correct.

4. Species interact with each other in their environments. Describe the relationship between the two species of
barnacles and the snail species. Use the words: symbiosis, predation, competition, fundamental niche, realized
niche.
|
Answers
Answer:
Predation is the relationship.
Explanation:
Predation is the relationship present between the two species of barnacles and the snail because snails feed on barnacles for their living. In the fundamental niche, the snail grow in population due to availability of suitable environmental conditions, but when there is realized niche, predation and competition exists which limits the growth of the population of organism. Here barnacles population is limited due to presence of snail which feeds on it.

What happens in the process of clearcutting?Clearcutting removes all the trees within a certain area at one time. Shelterwood cutting also removes all the trees in an area, but does it in stages over several years.
Seed-tree cutting removes all the trees except for a select number of mature trees that can then reseed the area. Seed-tree cutting and shelterwood cutting allow for the harvested areas to recover over time without direct intervention.
The scale of clear-cuts throughout Oregon is limited by law, although proprietors have been required to leave trees throughout specified locations to preserve waterways as well as provide wildlife habitats.
Therefore, Clearcutting removes all the trees within a certain area at one time. Shelterwood cutting also removes all the trees in an area, but does it in stages over several years. Seed-tree cutting removes all the trees except for a select number of mature trees that can then reseed the area.

-The top bird with a beak adapted for insect eating would not succeed on a Galapagos Island with little insects but plentiful seeds.
-The middle bird with a woodpecker beak adapted for seed eating most likely could dig deeper for larger, harder covered insects more successfully than the top bird with the insect eating beak.
-The bottom right bird with a beak adapted for seed eating would succeed on a Galapagos Island with plentiful vegetation and few insects.
Explanation:
The theory of natural selection explains that organisms undergo changes in their physical and genetic features that make it possible for them to adjust to their environments. There are different types of birds having different shapes of beaks adapted for life in several environments.
There are insectivorous birds whose beaks are adapted for eating insects, granivorous birds with short, conical beaks for cracking seeds, frugivorous birds adapted for eating fruits, nectivorous for sucking nectars, among others. The adaptations are unique to the birds and determine their survival and feeding habits in several environments.

Name one way that each of the three food
production systems (crops, meat, and fish/shellfish) can result
in environmental problems.
Answers
Answer:
Crops: Contamination by uncontrolled use of chemicals such as pesticides and fertilizers. Deforestation.
Meat: Water pollution with animal wastes, chemicals, and other toxic and contaminants. Deforestation.
Fish: Overfish and accessory capture.
Explanation:
Crops: Industrial farms make unconscious use of pesticides and fertilizers that penetrate the soil contaminating it, polluting water, and affecting plants and animals that live around that land and beyond. Animals and people exposed to pesticides such as insecticides, fungicides, and herbicides, have been shown affected by their effect.
Meat: Meat production turns to be one of the principal causes of water and soil pollution. Contaminants originate mostly from animal wastes (dung, blood), antibiotics, hormones, chemical substances used in the tannery, and sediments of eroded soils.
Both industries play a principal role in global deforestation. Most native forests get cut down to make a place for the development of these activities.
Fish: Overfish is one of the most important environmental problems caused by fisheries. Uncontrolled resource overexploitation leads to species´ extinction. Huge amounts of animals get caught in any of their stages of development. Young animals do not reach the reproductive stage, and reproductive females can not release eggs. This causes important damage to the reproductive rate of the species. Also, when overexploiting, many other unwanted species get caught and die on the nets. Accessory capture is the cause of death of many invertebrates, fishes, and marine mammals die because of the fisheries nets.
The three food items like crops, meat, and fish can lead to environmental problems by the release of GHG, overconsumption, and land degradation.
What aspect of the food items of the production system harm the environment. ?The food production system like the crops can lead to an increase of gases and removal of forest lands that leads to less habitat for wildlife. The production of meat either sheep, cow, buffalo, etc. will lead to the release of the GHG and increased resource depletion.
Overfishing will lead to the tragedy of commons and similar these aspects will lead to land degradation by excessive utilization of resources. Hence impacting the environment.
