Answer:

Water separates polar molecules from each other by forming hydrogen bonds.

Explanation:

A polar molecule is a molecule in which the distribution of electrons between the covalently bonded atoms is not even. This means that one end of the bond is slightly more positively charged, while the other end is slightly more negatively charged.

An example of a polar molecule is a molecule of water (H2O). Substances with similar chemical characteristics dissolve in each other. This means that polar molecules will dissolve in water. The partially negative part of a water molecule will interact with the partially positive part of another polar molecule. This results in the formation of hydrogen bonds, which occur when a hydrogen atom is located between a pair of other atoms that have a high affinity for electrons.

If a plant takes in 6 CO2 molecules and 6 H2O molecules in order to build one C6H12O6 molecule, what element will the plant have "extra" of / What element will be "extra"?

Answers

Answer:

Oxygen (O2)

Explanation:

This question is describing photosynthesis which uses carbon dioxide and water as reactants in the presence of sunlight to synthesize sugar (glucose) and oxygen. The general equation is as follows:

6CO2 + 6H2O ---> C6H12O6 + 6O2

According to this question, a plant takes in 6CO2 molecules and 6H2O molecules in order to build one C6H12O6 molecule. Using the balanced equation above, the extra element is OXYGEN, which still needs to be released as a gas for the equation to be balanced i.e 6O2 molecules

Describe the events that occur during the cell cycle. Include what happens in each of the following stages: interphase, mitosis, cytokinesis.

Answers

Answer:

Cell cycle or cell division refers to the series of events that take place in a cell leading to its maturity and subsequent division. These events include duplication of its genome and synthesis of the cell organelles followed by division of the cytoplasm.

interphase-During interphase, the cell copies its DNA in preparation for mitosis. Interphase is the 'daily living' or metabolic phase of the cell, in which the cell obtains nutrients and metabolizes them, grows, reads its DNA, and conducts other "normal" cell functions. This phase was formerly called the resting phase.

mitosis-In cell biology, mitosis is a part of the cell cycle, in which, replicated chromosomes are separated into two new nuclei. Cell division gives rise to genetically identical cells in which the total number of chromosomes is maintained.

Cytokinesis-Cytokinesis is the division of the cytoplasm in eukaryotic cells that produces distinct daughter cells. Cytokinesis occurs at the end of the cell cycle following mitosis or meiosis. In animal cell division, cytokinesis occurs when a contractile ring of microfilaments forms a cleavage furrow that pinches the cell membrane in half.

B. Robins and sparrows have different types of bases.
C. Robins and sparrows have different arrangements of the bases.
D. Robins and sparrows have the same arrangement of the bases.

Answers

Answer: the answer is C —> AP.EX

Explanation:

The nucleotide bases are the nitrogenous rings that form the backbone of the nucleic acid. Robins and sparrows have the same bases with different arrangements. Thus, option C is correct.

What are nucleotide bases?

The nucleotide bases or the nucleobases are the fundamental units that together with the sugar molecule and phosphate make the structure of the DNA or RNA.

There is a total of five nucleotide bases divided into purines and pyrimidines based on their ring structures. The purine consists of adenine and guanine, pyrimidine of cytosine, uracil, and thymine.

The bases are universal in organism containing the DNA or RNA but only differs in their arrangements that result in the development of the various traits and characteristics of the organism.

Therefore, in option C. the bases are arranged differently in species.

The concentration of a substance inside a cell is greater than outside the cell. What type of transport is needed to move molecules of the substance from outside the cell to inside?

Answers

Answer:

Osmosis

Explanation:

The type of transport needed to move molecules of the substance from outside the cell to inside is active transport.

What is active transport?

Active transport is the movement of molecules against a gradient or other form of resistance, for example from a lower to higher charge area.

Cells use active transport to accumulate molecules such as glucose and amino acids.

A cell must use energy to move compounds against such a concentration or electrochemical gradient.

Active transport mechanisms do exactly that, expending energy more often in the form of ATP to maintain proper ion and molecule concentrations in living cells.

In the given scenario, the concentration of substance is more inside the cell than outside and the substance has to move from outside to inside the cell. This requires energy for processing.

Thus, the given scenario can be accomplished using active transport.

Measure of soil quality which stays constant throughout a growing season is best describes the soil fertility.

What do you mean by soil fertility?

Soil fertility refers to the ability of soil to sustain agricultural plant growth, i.e. to provide plant habitat and result in sustained and consistent yields of high quality.

A fertile soil will contain all the major nutrients for basic plant nutrition (e.g., nitrogen, phosphorus, and potassium), as well as other nutrients needed in smaller quantities, e.g., calcium, magnesium, sulfur, iron.

The following properties contribute to soil fertility in most situations: Sufficient soil depth for adequate root growth and water retention; Good internal drainage, allowing sufficient aeration for optimal root growth.

Answers

Answer:

D. Sequence of nucleotides in the DNA of the cell.

Explanation:

Proteins are a type of biomolecules in living systems responsible for many phenotypic characteristics in organisms. Proteins are synthesized by a process called gene expression, which encompasses transcription and translation.

Using the central dogma of biology to trace, DNA (genes) contains information that encodes the production of proteins in the body. Therefore, the sequence of nucleotide bases in the DNA of a cell determines the sequence of mRNA that will be produced during transcription and ultimately, determines the specific type of proteins (amino acid chain) that will be produced in a cell during translation.
