Which produces the sediments that ultimately lead to soil formation? A. rivers B. plants C. weathering D. rainfall

I think the correct answer from the choices listed above is option C. It is weathering that  produces the sediments that ultimately lead to soil formation. Weathering is the breaking down of rocks, soil, and minerals as well as wood and artificial materials through contact with the Earth's atmosphere, waters, and biological organisms.

The higher invertebrates are divided into two evolutionary lines, protostomes and deuterostomes. This division is based on which developmental feature? A.wether the blastopore ultimately develops into a mouth or an anus B. wether the embryonic cells undergo spiral or radial cleavage C. wether the coelom forms by splitting the mesoderm or through the pocket of the gut.

Answer:

A. whether the blastopore ultimately develops into a mouth or an anus

Explanation:

The higher invertebrates are divided into two evolutionary lines named protostomes and deuterostomes based on whether the blastopore ultimately develops into a mouth or an anus. Blastopore is the first developement opening of archenteron (rudimentary alimentary canal) which appears during gastrula stage. If during embryonic development, the blastopore develops into mouth then the animal is known as protostome whereas development of anus from blastopore will make the invertebrate a deuterostome.

Invertebrates like annelids, arthropods and molluscs are examples of protostomes while echinoderms are examples of deuterostomes.

Which of the following body systems work together to get cells the nutrients they need to carry out cellular respiration ? A) the digestive and respiratory systems B) the respiratory and circulatory systems C)the digestive and circulatory systems D) the circulatory and excretory systems

I believe the correct answer from the choices listed above is option B. It would be the  respiratory and circulatory systems that work together to get cells the nutrients they need to carry out cellular respiration. They are responsible in providing oxygen and other nutrients throughout the body.

Why do you think plasmids and bacterial cells are such important tools in genetic engineering?

Plasmids contain extra nucleoid genitic material. By virtue of plasmids bacteria have won their battle againt the miracle drugs like penicillin, streptromycin, asprin etc. Well genitic engineering retrieves their adapted and evolved tendencies to be applied for a long lasting cure.


I hope my answers has come to your help. God bless and have a nice day ahead!

What do eukaryotic cells have that prokaryotic cells do not? A.Cell membranes B.DNA C.Cytoplasm D.Membrane-enclosed organelles

Answer:

The answer is D.Membrane-enclosed organelles

Explanation:

Eukaryotic cells have a cytoplasm organized in compartments, with separate or interconnected organelles, limited by biological membranes that have the same nature as the plasma membrane. In the nucleus is the genetic material in the form of chromosomes, where all the necessary information is given so that all the processes both intracellular and outside the cell are carried out.

What is the best explanation for why a cell might shrivel? A, There is less water in the cell than there is water in the environment surrounding the cell. B, There is more water in the cell than there is water in the environment surrounding the cell. C, The water solution in the environment surrounding the cell has a higher solute concentration than the cell. D, The water solution in the environment surrounding the cell has a lower solute concentration than the cell.

The right answer is C, The water solution in the environment surrounding the cell has a higher solute concentration than the cell.

Plasmolysis (the phenomena of shriveling cell) is a cellular state of the plant cell where, following loss of water, the membrane is detached from the pectocellulose wall. This is the opposite state of turgescence.

Plasmolysis occurs when a stream of water comes out of the vacuole and the plant cell through osmosis. The resulting decrease in pressure causes shrivelling of the soft parts of the plant (stems, leaves, petals), which are no longer supported by the turgor pressure.

This flow of water is created either by the lack of water in the external environment, or by the presence in this medium of a liquid more concentrated than the cellular medium. In these situations, there is a displacement of water by osmosis from the cell medium to the external medium.

Thus, the cells of a plant subjected to a drought or a water too concentrated in salts will lose their water and will be in plasmolysis. The soft parts will then shrivel up and the plant will die of water stress if the situation does not allow it to quickly reabsorb water.

In organisms other than plants, when and where is the most ATP produced? in thylakoids, during photosynthesis in nuclei, during cellular respiration in chloroplasts, during photosynthesis in mitochondria, during cellular respiration

Answer: In the mitochondria during the process of cellular respiration.

Explanation:

The food that we intake is in the form of either carbohydrate, fat and proteins. The food needs to be converted in the form of adenosine triphosphate which is used by the cells of the body.

The process of cellular respiration takes place in the mitochondria which is the site for the formation of ATP.

The cellular respiration is the process by which there is a conversion of carbohydrates into ATP.

How do plants get nitrogen? by carrying out photosynthesis by absorbing it from soil by carrying out nitrogen fixation or by absorbing it through evaporation

Answer: by absorbing it from soil

Explanation:

Nitrogen is an essential element required by the plants for their growth and metabolism that is for the synthesis of amino acids, proteins, and nucleic acids. The nitrogen is present in the earth atmosphere for about 78%. The plants cannot directly absorb atmospheric nitrogen instead they are capable of absorbing and utilizing the compounds of nitrogen such as ammonia, nitrates and nitrites. The atmospheric nitrogen is absorbed and fix in the soil by soil bacteria into compounds of nitrogen which can be easily absorbed by the plant roots from the soil.

The diagram shows the stages of the eukaryotic cell cycle. Which stage is labeled E in the diagram? mitosis interphase S phase G0 phase

Answer:

The correct answer would be interphase.

The cell cycle is mainly divided into two phases: mitosis (M) and interphase.

Interphase is the phase in which a cell spends most of its time. It is the phase of growth and DNA replication.  

It can be sub-divided into three stages:

  • Gap 1 (G₁) phase which is represented by letter A in the given diagram.
  • Synthesis (S) phase in which DNA replication takes place. It is represented by letter B in the given diagram.
  • Gap 2 (G₂) phase which is represented by letter C in the given diagram.

Letter D represents mitosis (M) phase in which the actual division of the cell takes place.
