A single carbon atom can form a maximum of how many single covalent bonds
A single carbon atom can form a maximum of 4 single covalent bonds.
Why can the carbon atom form this ?
This is because carbon has 4 valence electrons, which are electrons that are available to form bonds with other atoms. Each single covalent bond consists of 2 valence electrons, so a single carbon atom can form a maximum of 4 single covalent bonds.
Carbon atoms can also form double and triple covalent bonds, which consist of 4 and 6 valence electrons, respectively. However, a single carbon atom can only form a maximum of 4 covalent bonds in total.
I think it is carbon atom can form a maximum of 4 single covalent bonds... This is because it has 4 electrons and needs to reach a total of 8, so it can make up to 4 covalent bonds to gain the electrons it needs. I wish it help. Please comment
Which structure in plants allowed the first land plants to survive out of water?A. cuticle B. epidermis C. guard cell D. spongy mesophyll
The structure of plants that allowed the first land plants to survive out of water is known as the cuticle. Thus, the correct option for this question is A.
What were the first plants to live on land?
The first plants that were tends to live on land are the Non-vascular plants, which include mosses and liverworts, which were the first-ever land plants. They do not have much of an internal support system but have slightly simpler material for the same tasks.
Early in their history, land plants also evolved a cuticle. The cuticle is the structure that involves a waxy layer on the outer surface of the aerial parts of a plant that helps to prevent water loss. Sometimes cuticle with details of epidermal cell structure is preserved in fossil plants.
Guard cells play an important role in the opening and closing of the stomata. While epidermis is the outer cell which prevent the whole plant form injury.
Therefore, the structure of plants that allowed the first land plants to survive out of water is known as the cuticle. Thus, the correct option for this question is A.
Which of the following processes does not occur in both plant and animal cellsPhotosynthesis
The correct answer would be photosynthesis.
Photosynthesis is the process by which occurs only in plants and not in animal cells. Rest of the processes can occur in both plants as well as animal cells.
It is the process by which plant cells synthesize their food (glucose) from simple substances such as carbon dioxide and water in presence of chlorophyll and sunlight.
Chlorophyll is an essential element for the process of photosynthesis which is present in plant cells but absent in animal cells.
Photosynthesis does not occur in both plant and animal cells, while anaerobic respiration, aerobic respiration, and cellular respiration occur in both types of cells.
The process that does not occur in both plant and animal cells is photosynthesis. Photosynthesis is the process by which plants convert sunlight, water, and carbon dioxide into glucose and oxygen. Animal cells do not have chloroplasts, the organelles required for photosynthesis, so they cannot perform this process.
On the other hand, both plant and animal cells undergo anaerobic respiration and aerobic respiration. Anaerobic respiration occurs in the absence of oxygen and is less efficient than aerobic respiration. Aerobic respiration requires oxygen and is the most efficient way for cells to produce energy.
Cellular respiration refers to the overall process by which cells generate energy from glucose. It includes both anaerobic and aerobic respiration. Therefore, cellular respiration occurs in both plant and animal cells.
Why? - In an mRNA, the instructions for building a polypeptide are RNA nucleotides (As, Us, Cs, and Gs) read in groups of three. These groups of three are called codons. There are 61 codons for amino acids, and each of them is "read" to specify a certain amino acid out of the 20 commonly found in proteins.

What are two ways in which the geosphere is interacting with the hydrosphere in this river?
erosion and weathering
Penicillium notatum is what type of organism?
Penicillium notatum is a fungi. Penicillium is a genus of ascomycetous fungi which has a major importance in the natural environmen. It plays an important role in food and drug production as well. Some members of the said genus produce penicillin, a molecule that is used as an antibiotic. These antibiotics kill or stop the growth of certain kinds of bacteria inside the body.
Which scientific evidence would show that, for example two species of birds are closely related?
Scientists will look for evidence like similar body or skeleton structures, internal similarities or maybe sometimes the whole heirarchy to confirm that two speices are closely related to each other.
For example ; in birds, scientists will look for type of feathers, body structure, beaks to confirm the similarity of two birds.
