How many hydrogen atoms can bind to one carbon atom?

Biology
1 answer:
Damm [24]3 years ago
6 0

I think that the question is not clear enough. Can you be more specific?

If your question was something like this: how many atoms of hydrogen can be around carbon, then the answer is 4. Carbon forms 4 bonds with other atoms.

Please note that carbon need not always form bonds to four atoms. A carbon could form a double bond with an oxygen and then two single bonds to hydrogen atoms. The carbon is only bonded to three atoms, but is forming a total of four bonds (1 double and 2 singles).

Explanation;

-Domain Archaea is any of a group of single-celled prokaryotic organisms (organisms whose cells lack a defined nucleus) that have distinct molecular characteristics separating them from bacteria as well as from eukaryotes.

Insects often act as pollinators for plants. In turn, plants provide these insects with food. What kind of a relationship exists
sesenic [268]
A very strong relationship. I'll take the easiest example :the bees. They are so important for our planet. Without them, we and all living creatures on earth would be on track to dispariton. Let me explain why. At first, the bees need the nectar from flowers to make honey ( source of food ). As they pollen from flower to flower, they transport pollen on their tiny little legs and in this way, they help the plants to reproduce themselves. If, for some reason, there will be no more bees. Plants and flowers will not thrive, plants will be eaten without having contribued to the productivity of the species and they will go out. No plants, no more veggies or fruits for herbivorous and humans, no more herbivorous no more food for carnivorous, etc. Also, without plants, there will be less oxygen on our planet. Slowly the fauna and flora will die on earth and then it will be our turn. That is why relationships with plants and insects are so important. Plants produce oxygen for all of us and they are a natural and healthy source of food and insects help plants to survive and thus save the species.

stich3 [128]

ANSWER:

Problem faced include; habitat loss and degradation, disease outbreak, invasive species, pollution, over‐exploitation/overfishing, climate change etc.

EXPLANATION:

Problem:

Habitat loss and degradation, disease outbreak, invasive species, pollution, over‐exploitation/overfishing, and climate change are notable problems experienced by freshwater and marine fishes.

Solution:

Anthropogenic activities and stressors that rapidly threaten freshwater and marine fishes are curbed through legislation and other means to prevent extinction of fishes.

Through conservation programs that plans for individual species to more species of entire faunas of a particular location also boost population size and prevent hunting of threatened or endangered species in both realms.

Overtime, genetically modified fishes which can develop resistance to diseases are introduced to the realm.

Moreso, waste channels through which pollutants gets into the water bodies are well-treated for safety of fishes.
