Answer:
Explanation:
Carbon is a non- metallic element with tetravalent, which means carbon posses four electrons which is available to form covalent chemical bonds. it is a chemical element with chemical symbol "C" , it has atomic number of 6, and it is categorized as a member of group 14 in the periodic table. It can form up to 4 covalent bonds, in term of electronegativity, non- metal like Oxygen and nitrogen have a stronger electronegativity compared to carbon which means there is a strong pull on a shared electron. The carbon backbone of a molecule is made up of a string of carbon atoms held together with either single or double bonds.
1)A carbon atom can form up to four covalent bonds.
A. True
2. A carbon atom has six electrons in its outermost shell.
B. False
3. The bond between a carbon and hydrogen atom is a polar bond.
B. False
4. Oxygen and nitrogen have a stronger electronegativity than carbon (e.g., a strong pull on a shared electron).
A. True
5. Bonds between carbon and other atoms are relatively unstable and readily dissociate, resulting in the formation of new molecules.
B. False
6. The carbon backbone of a molecule is made up of a string of carbon atoms held together with either single or double bonds.
A. True
7. The carbon backbone of a molecule comes in a variety of shapes: linear, ring-like, or highly branched.
A. True
8. Carbon is a relatively large atom allowing it to bind to more atoms than smaller atoms would, thereby making it more versatile.
B. False
It is true that carbon atom can form up to four covalent bonds. It is false that carbon atom has six electrons in its outermost shell. It is also false that the bond between a carbon and hydrogen atom is a polar bond. The answers are A. True, B. False, B. False, A. True, B. False, A. True, A. True, and A. True.
Up to four covalent connections can be formed by a carbon atom. The reason for this is that carbon possesses four valence electrons, which enable it to share electrons with other atoms to complete its octet and create durable covalent bonds.
The outermost shell of a carbon atom only contains four electrons, not six. With a total of six electrons—two in its inner shell and four in its outer shell—carbon has an atomic number of six.
A nonpolar, not a polar, bond forms between an atom of carbon and an atom of hydrogen. Due to their identical electronegativities, carbon and hydrogen share the same number of electrons, resulting in a nonpolar covalent connection.
Compared to carbon, oxygen and nitrogen have larger electronegativities, which means that they exert more of a pull on the shared electrons in chemical bonds.
Under normal circumstances, bonds between carbon and other atoms are typically stable and do not easily dissolve.
A chain of carbon atoms bound together by single or double bonds makes up the carbon backbone of a molecule.
A molecule's carbon backbone can take on a variety of forms, such as straight, ring-like, or extremely branched ones.
Compared to lesser atoms, carbon is a comparatively big atom, which enables it to make numerous bonds and attach to more atoms.
Carbon's adaptability is a significant property that contributes to the complexity and diversity of organic compounds.
Thus, the answers are A. True, B. False, B. False, A. True, B. False, A. True, A. True, and A. True.

Explanation:
Adaptations that help an organism survive appear quickly. True or False? And why
Answer:
false
Explanation:
is not worth it to do that
According to the theory of natural selection, features that may be passed down help animals adapt to their surroundings more successfully than their kin.
What condition that make organism adaptive?Adaptations are passable traits that improve an organism's capacity to endure and procreate in a given environment. An organism can manage in harsh settings, locate food and water, and protect itself by adapting.
This is the outcome of a process called natural selection. A species' nature gradually changes as a result of natural selection in order for it to fit into the niche.
If a species becomes extraordinarily well adapted to its habitat and the environment does not change, it can survive for a very long time before going extinct.
Therefore, it is false that, Adaptations that help an organism survive appear quickly.

A powerful windstorm moves through a densely populated white oak forest. The oaks in this forest have either smooth or rough bark. The storm randomly knocks down 50% of the white oak trees. The remaining oaks grow and produce seeds that germinate and fill in spaces in the forest. All of the new oaks have smooth bark. Which of these processes is described in this example?
Answer:
Secondary succession.
Explanation:
These processes is known as Secondary succession because disturbance occurs in the environment due to powerful windstorm which eliminates rough bark oak tree while no damaged happen to the smooth bark oak tree. So the next time the plants grow in the place of rough bark oak tree because rough bark oak tree can't withstand in that type of environmental condition and all population is available of smooth bark oak tree due to their survival mechanism.
What would happen if a new cell does not contain chromosomes ( best answer with explantion will get brainliest)
a. the new cell will not have instructions on how to function
b.nothing, chromosomes are not important to cells
c. the new cell will reporoduce uncontrollably
d.the new cell wil grow but cannot duplicate itself in the future
a. the new cell will not have instructions on how to function
Because all the genetic material is stored in the chromosomes. Thus, all information is in it.
Answer:
a. the new cell will not have instructions on how to function
Explanation:
Genetic information contained within DNA molecules regulates cell growth, replication, and cell repair. The long-chain, helical macromolecules of these deoxyribonucleic acids are formed from complex sequences of nucleotide monomers- secondary strands contain a complementary sequence joined to the leading strand by hydrogen bonding.
Chromosomes are the double-stranded DNA helixes wound around small molecules called histones. Genes or sequences of DNA encode instructions for the cell, in the form of proteins. This occurs via: the transcription processes, translation to become proteins, defining physical traits or phenotypes.

Trilobites appeared approximately 521 years ago and disappeared approximately 250 million years ago. During which era did the trilobites live?
a
Cenozoic
b
Mesozoic
c
Paleozoic
d
None of These
Answer:
C. Paleozoic
Explanation:
Trilobites are a group of extinct marine arthropods. Just like many animals from today, including crustaceans, spiders, and insects, they belonged to the phylum Arthropoda. They lived in the Paleozoic era.
We can make this conclusion based on the fact that the period they existed in (from 521 to 250 million years ago) mostly fits the period described as Paleozoic (from 541 to 252 million years ago). However, we can see that they went extinct in the Mesozoic (250 million years ago is more than 252 million years ago). Compared to the entire time they existed, 2 million years is a relatively small amount of time, which makes Paleozoic the correct option.

Why is silicon distributed unevenly? Someone please answer asap I will give you a brainliest
Answer:
Inequalities in the exposure to environmental burdens and access to environmental benefits are an environmental justice concern for urban and regional environmental planning. Recent studies have assessed the exposure of different populations to a combination of environmental hazards through GIS-based Cumulative Environmental Impact Assessments (CEIA). The contribution of this study is the development of a CEIA, which incorporates the distance-based impact of transportation, the cumulative impact of environmental hazards, and access to environmental benefits for Santa Clara County (SCC), a highly diverse and rapidly developing region also known as ‘Silicon Valley’. Our results show that social vulnerability, cumulative environmental hazards, and environmental benefits exhibit distinct spatial patterns in SCC.

Why are water striders able to "walk on water"?
Answer:
Water striders can walk on top of water due to a combination of several factors. Water striders use the high surface tension of water and large hydrophobic legs to help them stay above water. Water striders use this surface tension to their advantage through their highly adapted legs and distributed weight.

D. Decomposers are generally from the animal kingdom,
while scavengers and detrivores are generally fungi and
bacteria.
Answer:
c
Explanation:
Decomposers chemically break down dead material, while detrivores and scavengers physically alter it by chewing and tearing. Therefore, option (C) is correct.
What are decomposers , detrivores and scavengers?Decomposers are organisms that perform the process of decomposition, which can only be accomplished by certain kingdoms, such as fungi, on dead or decaying organisms.
Detritivores are heterotrophs that eat dead or decaying matter to sustain themselves. Coprophagy is practiced by a wide variety of invertebrates, vertebrates, and plants. All these detritivores are doing their part to aid in decomposition and the cycling of nutrients.
A scavenger is an organism whose primary diet consists of decomposing matter. Carnivores, the group of organisms that primarily consumes meat, include many scavengers.
Therefore, option (C) is correct.
