Answer:

Saliva in the mouth acts to moisten and break apart food molecules

An example of mechanical digestion that occurs in the human digestive system is saliva in the mouth acts to moisten and break apart food molecules.

Mechanical digestion entails physically breaking down food substances into smaller particles so that chemical digestion can proceed more quickly.

Chemical digestion involves digestive enzymes further degrading the molecular structure of ingested compounds into a form that can be absorbed into the bloodstream.

Thus, the correct option is A. Saliva in the mouth acts to moisten and break apart food molecules.

Animal cells or plant cells??

Answer:

Explanation:Ribosomes are found in many places around a eukaryotic cell. You might find them floating in the cytosol. Those floating ribosomes make proteins that will be used inside of the cell. Other ribosomes are found on the endoplasmic reticulum.

Answer:

This question is not complete as it lacks options. However, it can be answered by giving the general differences between eukaryotic and prokaryotic transcription.

Explanation:

Eukaryotes are organisms that possess a membrane-bound nucleus that harbors their genetic material while prokaryotes are organisms that lack a membrane-bound nucleus.

Transcription is the process whereby a DNA template is used to produce an mRNA molecule. Below are the common differences in the transcription of eukaryotic and prokaryotic:

- Transcription in eukaryoric cell occurs in a NUCLEUS while transcription in prokaryotic cell takes place in a CYTOPLASM

- Transcription in eukaryotic cell requires proteins called TRANSCRIPTION FACTORS while transcription in prokaryotic cell does not require TRANSCRIPTION FACTORS.

- Transcription in eukaryotic cells occurs differently from translation while transcription in prokaryotic cells is coupled with translation i.e occur simultaneously.

Answer:

Berries and leaves are fully grown.

Explanation:

Blueberry plants are native to the northern hemisphere and belong to the Vaccinium genera and Ericaceae family.

They are deciduous shrubs that that are grown in cold-weather regions. They exhibit winter dormancy, which they induce with exposure to hours of cold.

If the winter is not hard, the plants might flower during this season, but if not, they do it at the beginning of the spring.

Blueberry plants can adapt to variable climatic conditions. However, temperatures lower than 5ºC might damage the buds. And temperatures over 36ºC might also damage the fruits.

Sunny summers favor the fruit quality and avoid pathogen development.

The collecting season varies according to the plant variety, but usually, harvests are done from late spring to late summer.

During the autumn, leaves turn reddish before falling, and buds develop once the vegetative growth is over.

Explanation:

Organisms in the ocean take Carbon Dioxide and turn it into carbonate CO 2/3

Carbonate is often combined with ions like CA 2+  and MG 2+

The Calcium Carbonate makes up the hard structures of corals, and sea shells. The amount of Carbon in the Coral reefs far exceeds the amount of Carbon Dioxide dissolved in the oceans.

Certain individual females in a population of deer decide to stop breeding with males that don't have antlers. This is an example of which Form of speciation A. Allopatric speciation.

Allopatric speciation occurs when two companies of organisms are separated by using a bodily or geographic barrier. Not unusual examples of those boundaries include mountain degrees, oceans, or even big rivers. The isthmus of Panama is a high instance of a geographical barrier and it separates the Atlantic and Pacific oceans.

In allopatric speciation, groups from an ancestral populace evolve into separate species due to a period of geographical separation. In sympatric speciation, agencies from the same ancestral populace evolve into separate species with no geographical separation.

Allopatry, which means 'in another area', describes a population or species this is bodily remoted from different comparable companies by an extrinsic barrier to dispersal. From a biogeographic angle, allopatric species or populations are those that do not have overlapping geographic levels.

Answer:

Explanation:

Sympatric speciation

Genes influence an organism's traits by coding for proteins. Therefore, option B is correct.

Genes are segments of DNA that hold the instructions needed to create a single, usually protein-producing, molecule in your body. These proteins regulate how our body develops and functions; they are also in charge of determining many of our physical traits, like our eye color, blood type, and height.

the information connected to a certain characteristic of the organism is encoded by these on the strands of genomic material; the entire strand of DNA or RNA is made up of numerous genes, each of which contains information. DNA is converted into RNA and then RNA is converted into protein.

Genes influence an organism's traits by coding for proteins. Therefore, option B is correct.

Explanation:

Variations in the population are necessary because it allows some individuals to acclimate to the environment while sustaining the survival of the population.

Genetic variations may be defined as the existence of differences in sequences of genes between individual organisms of a species.

Natural selection randomly favors or unfavors one genotype at a time. If there will not be any genetic diversity, it may lead to either extinction or population explosion of a particular genotype.

The genetic variations also depend on the relative fitness of a particular species. In order to resist at least one genotype of given species, genetic variations are important.

Therefore, variations in the population are necessary because it allows some individuals to acclimate to the environment while sustaining the survival of the population.

Answer:

The answer is the evaporation of water. As the gas begins to collapse, thermonuclear fusion as a result of the immense gravity at the center of the cloud results in the generation of immense heat and radiation that turns solids and liquid into gaseous form, close to the center of the cloud.

Explanation:

This resulted in the nuclear fusion of gases and dust to create the sun and planets at the outer flattened portion of the disk." The sun forms in the center of the cloud since the gravitation effect that drives thermonuclear fusion are strongest in this region. Planets form in the outer regions of the accretion disks where matter attract each other into clumps and gain even more gravitational pull to yank even more matter.

Answer:

There would be no seasons.

Explanation:

The tilt of the Earth's axis is what causes seasons. Throughout the year, different parts of Earth receive the Sun's most direct rays. So, when the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere. And when the South Pole tilts toward the Sun, it's winter in the Northern Hemisphere. If there was no tilt, the rays hitting the Earth would have minimal changes, meaning no seasons.

Answer:There are 3 elements in sodium carbonate i. e. sodium(Na) , Carbon (C) , Oxygen (O) .

Explanation:

Answer:

The correct answer is ''carbon dioxide, water vapor and nitrogen.''

Explanation:

About 4.5 billion years ago, Earth was a very geologically active planet. So many volcanic fumes formed the primitive atmosphere, which was mostly made up of water vapor, carbon dioxide, sulfur, and nitrogen. At this point, oxygen was barely present and the oceans did not yet exist. The primitive atmosphere is the one before the Precambrian, it was reductive, that is, it lacked free oxygen, and only had ammonia, methane and hydrogen, the high temperature of the atmosphere in its early stages facilitated the reaction of these gases to form organic compounds from which life may have emerged. UV rays passed, because ozone did not exist.
