For the first section take a look at a periodic table and fill it in . it tells u everything u need! i’ll send a example . the number of protons and electrons are the same. for every one ex: proton number= 3 electron number= 3 ! to determine valence electrons it’s differs on what column it is in on the periodic table. i’ll put in a picture to help aswell ! for the atom family number there is 18 of them. you would have to choose them based on the element. as for the dot structure. just search up a picture on line of that element dots structure and it will deffienly tell u and draw it. for the last ion part i would search it up on the internet! this is a lot of work but i know u can do it . sorry i couldn’t be or more help! if u have any other questions let me know i’ll be happy to guide u
Answer:
An area with an uneven distribution of food, water, moisture, temperature, or other resources can cause clumped dispersion. This pattern can also be caused by the formation of social groups based on protection or hunting. In plants, clumped dispersion is common when offspring fail to disperse from parent plants.
Answer: B. Level 1
Explanation:
The prairie community is dominated by the grass and vegetation cover. Thus the lower most trophic level in the prairie ecosystem are the short and tall grasses. They produce major source of biomass for the herbivores of the food chain. They consume the grasses can be designated as primary consumers of the food chain. Also the producers which are grasses which make up the large amount of biomass will provide a source of food for the consumers. They will receive 100 percent energy from the sun and they will utilize 90 percent of it to make their food by the process of photosynthesis. Only ten percent of energy is transferred to the next trophic level.

Explanation:
Answer:
C. glucose
Explanation:
Dark reaction takes place outside the thalakoid membrane (stroma and cytoplasm). During dark reactions, energy is released from ATP and NADPH to fix carbon dioxide into <em><u>glucose</u></em>.
Option A and B are not correct because they are produced during light reactions. Likewise, chlorophyll is the part of cell and is not prepared during light or dark reactions at all.
