Scientists have predicted that long-term effects of climate change will include a decrease in sea ice and an increase in permafrost thawing, an increase in heat waves and heavy precipitation, and decreased water resources in semi-arid regions.

Answer:

if the nucleotide insertion occurs within the coding region of a gene (frameshift mutation), then it will change the open reading frame (ORF) of the resulting protein and thus also will alter the phenotype of the individual  

Explanation:

A mutation is any change in the DNA sequence of the genome of a cell/organism. A point mutation is a genetic mutation where a single nucleotide is inserted, deleted or changed from the original DNA sequence. The insertion of a single nucleotide in the coding region of a gene is called frameshift mutation since this nucleotide base shifts the way the DNA sequence is read. A frameshift mutation changes the meaning of the codons that follow the inserted nucleotide base and thereby protein function is generally lost, thereby also affecting the resulting phenotype associated with this protein.

Answer:

The stable, end stage of ecological succession in which the plants and animals of a community use resources efficiently and balance is maintained by disturbances such as fire. The ultimate goal of ecological succession. After a natural disaster and continues until a climax community is reached.

Explanation:

The ultimate role of ecological succession in an environment is to reach the equilibrium in an ecosystem.

This event involve in the steady and gradual change in a species of a given area with respect to the changing environment is called as ecological succession.

The changes are inevitable process where all biotic components of the ecosystem keep up with the changes in our environment.

This process ultimately reach equilibrium in the ecosystem and the community that achieves this referred as a climax community, where some species increase in number and others decrease.

The communities that undergo changes sequentially in an area is called sere, so it is also called as seral stage or seral community.

Evolution has taken place simultaneously with that of ecological succession, so all the communities we observe are the result of ecological succession.

Owls can be found in all parts of the world except Antarctica.

Explanation:

Owls are found in many different habitats, such as deserts, forests, prairies, and even the Arctic tundra. They nest in trees, in holes in the ground, in barns, and in caves. And while many other birds migrate to warmer places during the winter, most owls do not. They live in the same place all year round. Antarctica is the only place in the world without owls because of the extreme temperatures of the ice desert, making it insanely hard for much life to exist there.

The stages of human gestation and their time duration are given below:

Fertilization may be defined as a biological event that occurs by the fusion of male and female gametes successfully to produce a zygote.

The embryo develops after four to five weeks of conception which is the first trimester, organs initiate to develop by the end of the first trimester.

Swallowing is initiated at the beginning of the second trimester, and all organs are completely developed by the initiation of the third trimester. While all senses of hearing and seeing are developed by the middle of the third trimester.

Therefore, each trimester is characterized with its own functionality.

CH3CH3  - ETHANE.

CH3CH2CH2CH2CH2CH2CH2CH2CH2CH3  - DECANE.

Explanation:

Hello there!

In this case, according to the rules for the nomenclature of organic compounds, it turns out possible for us to match the given hydrocarbons by knowing that octane is a hydrocarbon with eight carbon atoms, butane with four carbon atoms, methane with one carbon atom, decane with ten carbon atoms and ethane with two carbon atoms.

In such a way, the correct matching is shown below:

CH4  - METHANE.

CH3CH2CH2CH2CH2CH2CH2CH3  - OCTANE.

Fire extinguisher.

Explanation:

Fire extinguisher is the appropriate safety equipment to have at the side of the baker while heating a solution in a beaker because sometimes the solution catch heat due to reactions with flammable liquids which leads to big incident so in this case fire extinguisher can avoid such type of incident by turn off the heat due to the gas present inside the container of fire extinguisher so this safety equipment is necessary at the side of the reaction.

Explanation:

Greenhouse effect, a warming of Earth's surface and troposphere (the lowest layer of the atmosphere) caused by the presence of water vapour, carbon dioxide, methane, and certain other gases in the air. Of those gases, known as greenhouse gases, water vapour has the largest effect.

Explanation:

Plants produce two gaseous waste products i.e. oxygen during photosynthesis and carbon dioxide during respiration. Excretion of gaseous waste in plants takes place through stomatal pores on leaves. ... Excess of water is also excreted from the plant body through the stomatal pores and from the surfaces of fruits and stems.

No, prions are not considered organisms because they are proteins that the infection to the surrounding cells and tissue. Prion is a type of protein that can change normal proteins in the brain into abnormal. Prion diseases can affect both humans and animals and spread to humans by eating infected meat products. So we can conclude that prions are not organisms, they are proteins.

Answer:

1. c. because across a period from left to right, the covalent radius decreases. As you move from left to right across the periodic table, atoms have more electrons in their outer energy level and more protons in their nucleus.

2.b. because Transition metals are less reactive than alkali metals because of their high ionization potential and high melting point.

Answer:

Arrow no. 4

Explanation:

Water flows from a region of higher concentration to a region of lower concentration, i.e, osmosis.

Dilute solution means it has relatively less solute and more solvent, meaning more amount of water.

And just the opposite for concentrated solution.

So since the dilute solution has more water and concentrated solution has less, and water moves from a region of higher concentration to a region of lower concentration, option 4 is the correct answer.

During the osmosis process solvent is moved from a lower solute concentration to a higher solute concentration, hence arrow 4 defines the movement of water molecules.

Osmosis is the process through which solvents move from a region of lower solute concentration to one of higher solute concentration across a semi-permeable membrane.

Water in the cell acts as a solvent and moves from lower solute concentration to higher solute concentration through a partially permeable membrane.

Conversely, in diffusion, molecules migrate from an area of greater concentration to regions of lower concentration without the need for a semi-permeable barrier.

Therefore diffusion of water molecules in the osmosis process from low solute concentration to high solute concentration, hence arrow 4 defines the movement of water molecules.
