Viruses can only reproduce by infecting living cells
Answer:
1. in animal cell and 3. in plant cell In animals mitochondria transforms energy and chloroplast in plant cell absorb energy from sun light and turns water and carbon dioxide into glucose
Explanation:
1. Mitochondria: It is the powerhouses of a cell oval in shape found in eukaryotic cell.Its a site of cellular respiration. It converts glucose in chemical energy known as ATP (Adenosine triphosphate). ATP provides energy to carry out cellular function by breaking high energy bond.Mitochondria are abundant in cells requires energy to perform functions such as muscle and liver cells.
2. Chloroplast: In plants and algae chloroplast is a site of photosynthesis,it contains a pigment chlorophyll which captures energy from sunlight and turn water and carbon dioxide into glucose as food of plants.
What he did was say that evolution happened that over time the birds seemed to be changing
The step at which the researchers would do at the end of researching Edna is to amplify the amount of DNA.
Option (d);
<u>EXPLANATION:</u>
- The term EDNA means Environmental DNA.
- Invasive species in the waterway are the waterborne plants and animals who can likely cause effects to the human as well as the environment.
- If researchers want to use eDNA to look for invasive species in the waterway, they will first collect a sample.
- After cutting DNA into pieces, DNA would be precipitated in each sample.
- And in the end, the amount of DNA would be amplified in each sample to understand how it would cause harm to the environment.
Answer:
A. Because energy is lost at every level.
Explanation:
energy decreases as it travels from lower levels to upper levels--which is a logical observation you could make.
Think of it like this--if a fish eats a small organism, it will then spend some of the energy obtained from the organism swimming around--so when a larger fish eats our fish, the energy from the original organism will already be partially lost (from our fish swimming around).
This means that when this pattern continues over multiple levels, we keep losing energy--which limits the environment's capacity for organisms to survive.
Hope this helps, have a lovely day :)
