1.) Compare the roles of oxygen and carbon dioxide in autotrophs and heterotrophs. Which organism is an oxygen consumer and carbon dioxide producer? Which organism is an oxygen producer and a carbon dioxide consumer?​

Answers

Oxygen is used by both autotrophs and heterotrophs to release energy from glucose in a process known as cellular respiration.

Carbon dioxide is predominantly used in autotrophs to perform photosynthesis.

An autotroph is because they release oxygen during photosynthesis and require carbon dioxide to perform photosynthesis.

What are Autotrophs and Heterotrophs?

Autotrophs are those organisms, that are known to make their own food in the presence of sunlight. Example- Plants

Heterotrophs are those organisms that use the food that comes from the other organism in the form of fats, proteins, and carbohydrates. These organisms that feed on other are called as heterotrophs.

Thus, Carbon dioxide, however, is predominantly used in autotrophs to perform photosynthesis because they cannot get their food any other way. The type of organism that is both an oxygen producer and carbon dioxide consumer is an autotroph.

Oxygen is used by both autotrophs and heterotrophs to release energy from glucose (as we know, the bonds between organic compounds can be used to release energy) in a process known as cellular respiration. Carbon dioxide, however, is predominantly used in autotrophs to perform photosynthesis because they cannot get their food any other way. The type of organism that is both an oxygen producer and carbon dioxide consumer is an autotroph. This is because they release oxygen during photosynthesis and require carbon dioxide to perform photosynthesis.

1: Why are siblings not genetically identical even if they have the same parents?2: Why are offspring not genetically identical to either the parent in sexuall reproduction?

Answers

each sperm and egg cell combine differently, so even if the parents are the same, the genetic material in their reproductive cells is different and can combine in different ways. the children are not clones of their parents, rather combinations of their traits

If i show a dominant trait do one of my parents have to show the same trait? explain?​

Answers

well, not exactly like some parents have blue eyes and they have a dominant brown eyed child. This can happen because of the gynotype. The history of the child’s parents probably have some brown eyes which caused the child to have brown eyes. But usually the parent does express a dominant trait like the child.

Sunlight is for the first question, Salinity for the second, and Density for the last one. Now you just have to explain why they relate to each other. Example: Some sea stars live on the bottom of the ocean where there is no sunlight and thus food is not the same as it would be in shallower waters. Due to the lack of sunlight, there are scarce amounts of nutrition that falls to the ocean floor for sea stars to eat. Now you just have to relate the other two questions with their properties.
Sunlight, density, and salinity I think.

What is cell theory?

Answers

Here are the main theories of the cell theory.

1. All living organisms are composed of one or more cells.

2. The cell is the basic unit of structure and organization in organisms.

3. Cells arise from pre-existing cells.

cell theory states that the cell is the basic unit of living organisms. Before the discovery of the cell, people were unaware that living organisms were made of building blocks of cells
