what does the process of breaking and reforming bonds allow cells to make?

Answers

Synthesis releases energy because the molecules bond to form a stable configuration and therefore give up energy. The bonded molecules have a lower energy level than free molecules and are held in the new bond.

The process of breaking bonds between molecules and the making or reforming of bonds encompasses chemical processes which allows the creation or formation of new molecules.

When bond is broken such that a certain element splits from a compound, new molecule is formed. Endothermic processes required energy to break bonds between atoms.

Bond making on the other hand are exothermic processes which involves merging of bond accompanied by the release of energy to form new molecules.

Therefore, bith Endothermic and exothermic processes allows cells to make new molecules.

A. natural selection: genetic engineering; artificial selection: demands placed on the brain
B. natural selection: individual mating choice; artificial selection: diseases
C. natural selection: diseases; artificial selection: genetic engineering
D. natural selection: demands placed on the brain; artificial selection: diseases

Part C

Projected values are only estimates. Can you think of either a natural or artificial factor that could increase or decrease the actual amount of wind energy the United States produces in the future?

Edmentum sample explanation:

Technological advancements in the future could lead to the production of higher-efficiency turbines, which could generate more electricity than originally predicted. Climate changes over time could affect wind speeds in a region, leading to higher or lower energy production.

The factors that would exert influence through the process of natural selection are a natural selection: diseases; artificial selection: and genetic engineering. The correct option is C.

What is natural selection?

The strongest survive through natural selection, and the most favored traits endure through evolution. Natural selection is the result of selection pressure on a population's frequencies of a specific allele. Evolution is the process through which, over an extended period of time, new sets of naturally selected organisms emerged.

Future technological developments might result in the creation of turbines with a higher efficiency, which might produce more electricity than was initially anticipated. Wind speeds in a place may alter as the climate shifts through time, which could result in increased or decreased energy output.

Therefore, the correct option is C. natural selection: diseases; artificial selection: genetic engineering.

Adaptations that help an organism survive appear quickly. True or False? And why

Answers

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.

According to the electronic configuration, when hydrogen shares electrons with oxygen , hydrogen atom has 2 electrons and oxygen atom has 8 electrons.

What is electronic configuration?

Electronic configuration is defined as the distribution of electrons which are present in an atom or molecule in atomic or molecular orbitals.It describes how each electron moves independently in an orbital.

Knowledge of electronic configuration is necessary for understanding the structure of periodic table.It helps in understanding the chemical properties of elements.

Elements undergo chemical reactions in order to achieve stability. Main group elements obey the octet rule in their electronic configuration while the transition elements follow the 18 electron rule. Noble elements have valence shell complete in ground state and hence are said to be stable.

Which of these is a characteristic of sexual reproduction?A)It takes place in all cells of the body.B)It forms exact copies of the parent cell.C)It results in offspring with genetic variation.D)It requires only one parent to form a daughter cell.

Answers

Answer/Explanation:

It results in offspring with genetic variation. 2 different mates must be used in sexual reproduction. This is because each person is different since cells are produced and combined differently in the original offsprings. If the two adults were exactly the same, the offspring would have the exact same cell traits. Likewise will be done for the offspring of the two adults. The genes may be similiar to the ones of the adults, but since combined it will not be an exact replica. In the long run sexual reproduction will result in an offspring with slightly different traits or genetic variation.

The correct answer is:

Option D. Cell parts such as chloroplasts are self-replicating.

The postulates of the cell theory are:

1. The cell theory states that all living cells arise from pre-existing cells.

2. The cells are the basic structural and functional unit of life.

3. The hereditary information is passed on from cell to cell, and the energy flows within the cell.

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

Answers

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.
