Answer:

A

Explanation:

Genetic material is what passes down traits and makes us look similar to our parents

When we talk about heredity, we're talking about the precise ways that genes are used to transmit traits or characteristics from one generation to the next, hence option A is correct.

The instructions for creating certain proteins, which are in charge of an individual's distinctive qualities, are encoded by genes.

The youthful creation of living creatures, known in biology as progeny, can be created by a single organism or, in the event of sexual reproduction, by two organisms.

DNA (deoxyribonucleic acid), which makes up genes, contains instructions for how cells should function as well as the traits that distinguish each individual.

Therefore, each of your biological parents contributes half of your DNA to you, and you could inherit a gene mutation from one or both of them, hence option A is correct.

Answer:

It is false as there is oxygen in all four.

Answer:

The correct answer is option A. muscle cell, muscle tissue, biceps, muscle system, and human being.

Explanation:

In humans and other mammals, there is a specific type of structural organization found in which involves fundamental units to the most exclusive level of organization. The cell is the most basic and fundamental unit of the organism's structure.

Cells joined together to form tissues like muscle cells form muscle tissues, tissues grouped with each other into organs like muscle tissue form biceps, different organs are grouped into organ systems like muscle system form from organs, and many organ systems come together to form complex organisms like human beings.

Answer:

they all excrete,grow and develop, reproduce and some move and locomote

Answer:

If an organism has a beneficial trait, they have a higher chance of survival, and if they can survive they can reproduce too.

Example: Speckled moths camouflage with the bark of trees and are not easily seen by predators. Black moths do not camouflage with the bark of trees and are easily seen by predators, therefore the black moths are eaten. Because the black moths have been eaten they cannot reproduce and pass on the trait for black wings to their offspring, but the speckled moths are able to reproduce because they survived and are able to pass on the speckled wing trait to their offspring.

Explanation:

Answer:  C. HYDROLYSIS

Explenation: Chemical weathering occurs when water dissolves minerals in a rock, producing new compounds. This reaction is called hydrolysis. Hydrolysis occurs, for example, when water comes in contact with granite.

Landforms are created through destructive forces such as weathering, so abrasion is an example of physical weathering that is in Option B as the physical weathering is a type of weathering that involves mechanical breakdown.

Physical weathering is caused by physical forces, such as the expansion and contraction of rock due to changes in temperature and abrasion is a specific type of physical weathering that occurs when rock or soil is rubbed against other rock or soil. In physical weathering, rock fragments or particles are carried by water, wind, or ice, and the repeated collisions and friction caused by abrasion can lead to significant changes in the shape.

Hence, landforms are created through destructive forces such as weathering, so abrasion is an example of physical weathering that is in Option B as the physical weathering is a type of weathering that involves mechanical breakdown.

Answer:

The prefix pro- primarily means “forward” but can also mean “for.” Some words that the prefix pro- gave rise to are promise, pro, and promote. When you, for instance, make progress, you are stepping “forward,” whereas if you give the pros in an argument, you are speaking “for” something by stating its advantages.

Answer:

1. Red flowers: RR, White flowers: WW, Red & white flowers: RW

2. Incomplete dominance

3. Purebred

4.Offspring are more rapidly produced

5. 100% red flower offspring, 0% white flower offspring

Answer:

No

2. Yes

Explanation:

This is because DNA undergo transcription to produce RNA and RNA undergo translation to produce protein. Translation is the process where mRNA molecule is used as a template to produce protein.

RNA undergo mutation more than DNA and this is because the enzymes found in RNA viruses and participate in copying viral genomes is why it occur so. These enzymes does not have the abilities to recognize DNA damage that enzymes in most organisms have.

Noroviruses are a group of viruses that cause gastroenteritis in people. Gastroenteritis is an inflammation of the lining of the stomach and intestines, causing an acute onset of severe vomiting and diarrhea. Norovirus illness is usually brief in people who are otherwise healthy. an RNA virus of the family Caliciviridae, is a human enteric pathogen that causes substantial morbidity across both health care and community settings, causes vomiting and diarrhea. People of all ages can get infected and sick with norovirus. Norovirus spreads easily! You can get norovirus by accidentally getting tiny particles of feces (poop) or vomit from an infected person in your mouth.

Answer:

D.The similar time period in which the organism lived

Answer:

The correct answer is - B. sympatric speciation.

Explanation:

The allopatric speciation occurs in the population that is geographically isolated, parapatric speciation takes place due to reproductive isolation however they occupy distinct nice or habitat.

Peripatric speciation is shows resemblance to allopatric speciation in terms of preventing the exchange of genes however they occur in the small peripheral population.

Sympatric produces a reproductive barrier between the small population that shows change to the parent population.

Answer: 3. Atmospheric CO2 -> plants -> animals -> fossil fuels -> factories

Explanation:

The carbon cycle is one of the types of biochemical cycles in which carbon is recycled in atmosphere, biosphere, lithosphere, and hydrosphere in various forms. The atmospheric carbon dioxide is absorbed by the plants and they utilize it as reactant for the process of photosynthesis in which they synthesize their own food. These plants are consumed by animals further when these plants and animals die their remains form fossil fuels deep beneath the earth crust. It takes about millions of years for fossil fuels to form in the sedimentary rocks. The fossil fuels are utilized by the factories to run their machines. Again when fossil fuels burn they emit carbon dioxide gas in the atmosphere.

Answer:

The nonliving processes such as evaporation, precipitation, etc., water returns back into the atmosphere.

Explanation:

Water moves through the help of living organisms in an ecosystem.

Although, the non-livings processes are also the main partners of this process.

Plants absorbs water through their root system and loss by transpiration.

Water also moves through the living organisms in an ecosystem.

Other nonliving processes such as evaporation, precipitation, water returns back into the atmosphere.

Answer:

Explanation:

Answer: The idea that the earth is extremely ancient.

Explanation:

Charles Darwin was a British naturalist who worked on the organic evolution of living organisms and in his books outlined how present-day organisms evolved from earlier, different species.

Evolution is an extremely slow process. It is difficult to obtain direct evidence of evolution in action. However, scientist including Charles Darwin, have from many fields gathered a great deal of indirect evidence that supports the theory of evolution. This evidence comes from many sources which include the FOSSIL RECORDS.

The history of life on earth is recorded in fossils (remains of organisms preserved mainly in earth's sedimentary rocks). Scientist can determine the age of rocks in which fossils occurs by using RELATIVE DATING. This method give a geological time scale, showing earth's age ( as measured by dating it's rocks), and tracing the history of life on it.

Therefore the idea that the earth is extremely ancient is associated with relative dating which has helped inspire Charles Darwin's work as an evidence on evolution.

Answer:

3 (solar to chemical, chemical to kinetic, kinetic to thermal)

Explanation:

Michael ate a salad. The salad which he consumes becomes chemical energy, but the tomato he put in his salad has used solar energy, which is simply energy from the sun. The kinetic energy is when he runs 2 miles as kinetic energy is the energy gained from movement. When he stops running, he sweats, which means he is losing heat from his body, therefore the kinetic energy store transfers to the thermal (internal) energy store.
