Does respiration expend more energy than photosynthesis?
Answers
Answer:
Explanation:
Photosynthesis vs Cellular Respiration Photosynthesis and cellular respiration are two basic metabolic processes occurring in the energy conversion of ecosystems. During photosynthesis, carbon dioxide and water are used in the synthesis of organic compounds with the aid of sunlight. This organic compounds can be used by cells as food. During cellular respiration, energy in the form of ATP is produced by breaking down food. The main difference between photosynthesis and cellular respiration is that photosynthesis is an anabolic process, where the synthesis of organic compounds occurs, storing energy whereas cellular respiration is a catabolic process, where the stored organic compounds are utilized, producing energy.

Answer D
A structure that performs a specialized function within a cell is known as is system.
What is system?Humans and other sophisticated multicellular organisms have coordinated organ systems that perform the functions necessary to sustain life.
The body is organized at many stages that progress together. Organ systems are made up of tissues, which in turn are made up of tissues and organs.
The coordinated activity of an organ system's organs determines how well it functions. In sophisticated multicellular animals like people, the cells are arranged into tissues, which are collections of comparable cells that collaborate on a particular activity. Organ systems are collections of organs with connected.
Therefore, A structure that performs a specialized function within a cell is known as is system.

Asexual Reproduction occurs when there is only one parent that gives rise to an offspring which has the identical genetic makeup of the parent. It occurs in most single celled organisms such as bacteria and some multicellular organisms such as fungi and some plants. Some advantages of asexual reproduction are it is fast and efficient. It does not require a male and a female. Organisms can reproduce quickly! A disadvantage is that there is no genetic diversity and it can only be done by simple organisms.
Sexual Reproduction involves the combining of genetic information from two parents to produce a new organism that is a combination of both parents. It occurs in most complex organisms. Some advantages to sexual reproduction are that it creates genetic diversity. It allows for evolution of the species. A disadvantage is that it requires two organisms to reproduce, a male and a female. It also requires more energy than asexual reproduction.
Using the table below, list at least two advantages and disadvantages of Asexual and Sexual Reproduction.
asexual reproduction sexual reproduction:
advantages: advantages:
disadvantages: disadvantages:
Answers
Advantages: A species can evolve or adapt to changing environments, genetic diversity
Disadvantages: Time and energy needed to find a mate, requires both male and female gametes, one individual cannot reproduce
Asexual reproduction:
Advantages: Only one individual is needed to reproduce, doesn’t require time or energy to find a mate, can reproduce rapidly in good conditions
Disadvantages: No genetic variation, all of the offspring have the same weaknesses, can’t adapt or evolve
