Physical properties of the atoms are the properties which can be easily observed without any change in the identity of a substance. Thus, the correct option is B.

The physical properties can be defined as the properties which can be measured easily. Physical properties refer to the measurable value of the object which can be used to describe the state of the physical system.

The physical properties can be observed through different methods, hence they are also called as the observable properties. They are not the modal properties.

Any change in the physical properties describes the changes between the momentary states of the object or the substance. Physical properties can be observed without any change in the identity of the object.

Therefore, the correct option is B.

The finches on the Galapagos Islands are a good example of adaptation because they all trace their ancestry into a small group of finches that inhabited these islands, but diversified in accordance to the environment. On the Galapagos Islands, there are finches that have numerous types of different beak shapes and sizes, despite them all being derived from a single group of finches that had the same characteristics. The reason for this is that once they got to these islands, there were multiple niches int the food chain that were free for taking. Some finches started to feed on plants, some on seeds, some became insect-eaters etc. Every food type needs special adaptation so that the finches can eat it more easily, or even be able to get to its nutritional part, thus their beaks started to change in accordance to their food preference.

Cells without the correct antigen proteins are foreign and are tagged with antibodies for destruction.

Answer: Option B

Explanation:

Whenever a foreign particle enters our body , our body’s own defense mechanism that is the immune system gets activated. This immune system comprises of certain antibodies that get tagged to the foreign moiety and takes it for destruction.

One more added advantage of these antibodies is that they remember the structure of the foreign particle that affected our body and thereby exerts double the force when the particle re-inters the body.

An oxygen molecule contains only oxygen. Nothing else.

That makes C wrong.

A is wrong because there needs to be 2 oxygens. The bonding rules for the non metals vary, but in general they are even numbers. They are also fixed. Oxygen happens to bond 2 oxygens for 1 molecule.

D is wrong. See the explanation for C. The number is fixed. It is 2.

B is the correct answer.

↪  Eutrophication ----> Nutrients in excess amounts enter water systems causing algal bloom

↪  Biomagnification ----> A high concentration of Toxic chemicals present in Bodies of Animals...

↪  HOPE THIS HELPS

❤Gianna❤

Answer:

1. Acid Rain matches with the first statement.

2. Eutrophication match with the second statement.

3. Biomagnification match with the third statement.

Explanation:

Acid Rain is any type of precipitation having acidic components that fall to the earth surface from the atmosphere and enter in the water cycle.

It can be dry also, acid rain affects affect living beings and water bodies in many ways.

The increase in the concentration of toxic chemicals or substances in the tissues of living beings at successively higher trophic levels in a food chain is biomagnification. The most common example of eutrophication is nitrogen and phosphorus which come from runoff from agricultural land and from detergents.

The enriched with nutrients in any body of water or lake causes the death of animal life and a dense growth of plant life from lack of oxygen.

the answer i believe  is "total number of hydrogen atoms carbon dioxide and oxygen" pls make me a brainliest

Answer:

Total number of hydrogen atoms in carbon dioxide and oxygen

Explanation:

Cellular respiration is the biochemical process that cells perform to remove energy from molecules and use that energy in their vital processes. The two main types are anaerobic breathing (without the use of oxygen) and aerobic breathing (with the use of oxygen). The cell respiration process involves several steps. Cellular Breathing is one of the main activities of cells, as it is through this process that the cell can produce energy for all its functioning.

During cellular respiration, the total number of hydrogen atoms in the water is equal to the total number of hydrogen atoms in carbon dioxide and oxygen.

1. C) Greenhouse Effect

2. D) Fossil Fuels

3. D)All of the Above

:)

Increased carbon in the atmosphere intensifies the greenhouse effect, a principal cause of global warming. The burning of fossil fuels is an example of human activity that releases carbon dioxide into the atmosphere. Further, carbon mixes with the atmosphere and water, impacting both.

Increased carbon in the atmosphere intensifies the greenhouse effect. This is because carbon, particularly in the form of carbon dioxide, is a major component of greenhouse gases. These greenhouse gases trap heat in Earth's atmosphere, contributing to global warming. An example of this is the burning of organic materials such as fossil fuels which release carbon dioxide into the atmosphere.

Carbon can mix with a variety of substances including the atmosphere and water. When carbon dioxide is dissolved in water, it can form carbonic acid, which contributes to ocean acidification. In the atmosphere, carbon gases contribute to the greenhouse effect.

it is hard to calculate the carrying capacity of the earth because not all of the planet is inhabited and with the way that us humans can grow food practically anywhere the capacity cannot be accurately determined.

Answer:

Explanation:

Carrying capacity is the maximum members of population of species which an environment can support on the basis of presence of resources.

It is difficult to calculate the carrying capacity of planet earth for human beings. As not all land over earth is occupied by humans and the population of human beings increasing exponentially worldwide. Due to their intelligence and ability to solve problems related to scarcity of resources. The carrying capacity of humans is difficult to determine.

Explanation:

the atom that is most closely associated to living things is carbon

Answer:

Carbon

Explanation:

Carbon is associated with living beings by participating in the metabolic needs of these organisms, being the chemical basis for the essential molecules (such as proteins, carbohydrates and lipids) of living things.

Carbon is also present in the photosynthesis reaction of plants, where the sun's energy reacts with carbon to generate oxygen.

In addition, carbon is present in many foods, particularly carbohydrates, which when eaten by animals, are converted into energy to help them stay alive.

An increase in the total biomass of consumers in the world

Answer:

a decrease in the total biomass of consumers in the world

Explanation:

A decrease in carbon fixation would likely increase the amount of carbon dioxide in the air and decrease the amount of oxygen. This would change how much respiration and photosynthesis could take place, resulting in:

a decrease in the total biomass of consumers in the world,

an increase in the total biomass of producers in the world, and

a decrease in the size of insects and arthropods, since their ability to move oxygen from the air into and through their bodies is limited.

The Moon's Two Shadows. An eclipse of the Sun (or solar eclipse) can only occur at New Moon when the Moon passes between Earth and Sun. If the Moon's shadow happens to fall upon Earth's surface at that time, we see some portion of the Sun's disk covered or 'eclipsed' by the Moon.

HOPE THIS HELPED!!!! XD

C. There would be a partial eclipse.  What would most likely happen if the moon was not directly in front of the earth is a partial eclipse.

A partial eclipse occurs when the Moon or Earth is not perfectly aligned with the Sun, so only part of the Sun or Moon is obscured.

A partial solar eclipse occurs when the Moon is not perfectly aligned between the Earth and the Sun. The Moon’s penumbra partially covers the Sun, leading to a partial eclipse of the Sun.

A partial lunar eclipse occurs when the Earth’s shadow partially covers the Moon. The alignment is such that only part of the Moon enters the Earth’s shadow.

C. DNA molecules

Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.

Final answer:

The chromosomes in a cell nucleus are made up of C. DNA molecules, which contain the cell's genetic information in the form of genes.

Explanation:

Chromosomes within the nucleus of a cell are composed of deoxyribonucleic acid (DNA) molecules. Each chromosome is a single DNA molecule complexed with proteins, which include histones, that assists in the organization and compaction of these DNA molecules.

Each chromosome is a single DNA molecule wrapped around proteins. Genes are relatively short segments of DNA that contain the code for the creation of a protein. The DNA within these chromosomes carries genetic information in segments called genes, which are responsible for the inherited characteristics of an organism.

A restriction map is a map of known restriction sites within a sequence of DNA. Restriction mapping requires the use of restriction enzymes. In molecular biology, restriction maps are used as a reference to engineer plasmids or other relatively short pieces of DNA, and sometimes for longer genomic DNA.

Agriculture significantly contributes to the amount greenhouse gases emitted into the atmosphere. This is cause by several aspects of agriculture. For instance, livestock generate more greenhouse gases (methane from the wastes they produce) worldwide than all modes of motor-vehicle transportation combined. There's also the aspect of deforestation. Trees help reduce greenhouse gases in the atmosphere by taking CO2 from the air.  Therefore, cutting down trees in order to plant crops/raise livestock is indirectly adding to the amount of greenhouse gases in the atmosphere. Agriculture also requires the uses of engines to harvest and transport crops (ex: tractors plowing the soil or trucks transporting crops to grocery stores), which creates greenhouse gases as well.

Answer:

The letter C is the right answer.

Explanation:

According to salinity, we can divide the water into fresh, brackish and salty. Freshwater has a small amount of salt (less than 1%), so, despite the term, we must make it clear that it does not contain sugar. This is the water most used by man and is available in rivers, lakes and underground reserves. It is estimated that it represents only 2.5% of the total water on the planet.

I think the answer would be 2.) Micro evolution is the change in the gene pool and macro evolution is the formation of a new species.

Microevolution refers to small evolutionary changes within a species' gene pool, while macroevolution describes larger evolutionary changes that lead to the formation of new species over long geological time periods.

The terms microevolution and macroevolution refer to different scales of evolutionary changes in organisms. Microevolution is the change in allele frequencies that occurs over time within a population, leading to adaptations and variations within a species. This process includes the natural selection of advantageous traits, genetic drift, mutations, and gene flow. It occurs on a relatively small scale and often over a short period of time. In contrast, macroevolution involves the evolution of entire taxonomic groups over long periods of geological time, leading to the emergence of new species (speciation), extinction events, and the evolution of major new features or body plans. It includes the accumulation of microevolutionary changes that lead to the formation of new species and larger evolutionary changes.
