Answer:

As well as changing the way living things were classified, Linnaeus also changed the way they were named. He introduced a simpler method. ... This is rather like our system of giving people a first name and a surname. Each species has its own unique binomial which is the same throughout the world, thus avoiding confusion.

Answer:

I would say the correct answer is c

Explanation:

The statement that could be added to A is phosphate. The correct option is B.

Deoxyribonucleic acid is a polymer made up of two polynucleotide chains that coil around each other to form a double helix that contains genetic instructions for the development, functioning, growth, and reproduction of all known organisms and viruses. Nucleic acids include DNA and ribonucleic acid.

The fraction of the DNA double helix that supplies structural support to the molecule is known as the phosphate backbone.

The DNA molecule is made up of two strands that wind around each other like a twisted ladder. Each strand has an alternating backbone of sugar (deoxyribose) and phosphate groups.

A nucleotide is made up of a sugar molecule (ribose in RNA or deoxyribose in DNA) linked to a phosphate group and a nitrogen-containing base.

Thus, the correct option is B.

Answer:

The graph is positive.

Explanation:

Straight line on the graph indicates that the rate of reaction is positive which means that reaction intensity increases with the passage of time. OR in other words, the reaction produces more products with the passage of time and no decrease occurs in their rate because the graph is not coming downward or changing so that's why the graph go in the straight line.

Answer:Protein is evaluated at ≈55% of the cell dry weight, followed by RNA at ≈20%, Lipid at ≈10% and DNA at ≈3% (the rest being polysaccharides, metabolites, ions etc.).

Explanation:

A typical mammalian cell averages 18% protein and 0.25% DNA by weight composition.

According to research, a typical mammalian cell is made up of water, ions, and macromolecules such as proteins, lipids, DNA, RNA, carbohydrates, and some miscellaneous metabolites.

The water component of a typical mammalian cell is about 70%, 18% proteins, 1% inorganic ions, 3% small metabolites, 5% lipids, 0.25% DNA, 1.1% RNA, and 2% polysaccharides.

Answer:3

Explanation:

Answer:

The correct answer is - option C. proton gradient or energized membrane.

Explanation:

The transport chain reaction or system produces the ATP which is caused by the movement of the proton through the internal membrane from the matrix to intermembrane space by the protein complex.

This makes a concentration gradient of protons that moves through the membrane of mitochondria which is utilized by the enzyme known as ATP synthase to produces ATP molecules by oxidative phosphorylation.

Explanation:

Answer:

Behavioral isolation is demonstrated in species of finches. Their mating calls are distinct yet unique across species.

Explanation:

Mutations arising from errors within gene replication often accumulate within populations, becoming more stable. They may lead to the formation of separate, genetically distinct populations called species. These new species arise via:

Behavioral isolation is an isolating mechanism that is part of sympatric speciation. Here, there are apparent non-physical barriers to prevent mating, and several related species live within a population and gene-flow.  However, reproductive isolation occurs through assortative mating (mate choice based on shared traits) which may lead to heteropatric speciation.

Commonly observed in birds, it involves distinct and unique courtship and mating signals. Mates only respond to those fitting the required behavioral patterns such as a courtship dance, nest building, foraging and songs.

Answer: RNA polymerase

Explanation:

A) If you were to examine the membrane lipid composition of cells from the Channichthyidae fish, what you would expect to find is glycoprotein,zona pellucida protein and a less number of haemoglobin that is found in this type of fish.

B) Justification of why you might find what was identified in part (A) is because;

Glycoprotein contains antifreeze compounds,these antifreeze compounds are what provide resistance to freezing of their hypoosmotic tissues by the subzero environment.

If we analyzed the lipid composition of these fish, we could find glycoproteins.

We can arrive at this answer because:

In this case, the glycoprotein is an essential molecule in the organism of living beings that live in environments with very low temperatures, such as fish Channichthyidae.

During the process of photosynthesis plants convert light energy into chemical energy and can be stored in the molecular bonds of organic molecules.

Photosynthesis is the process in which green plants prepare their own food in the presence of sunlight and light energy is converted into chemical energy by the process of cellular respiration.

The process of photosynthesis takes place in green plants only due to presence of chlorophyll and materials such as sunlight, water, carbon dioxide is required for the process of photosynthesis.

The equation of photosynthesis is represented below:

[tex]6CO2+ 6H2O - C6H12O6 + 6O2[/tex]

The process of food manufacturing in plant is done through photosynthesis and the plants are known as autotrophs as they are the producers.

In the process of photosynthesis the reactant have 6 carbon dioxide molecules and six water molecules, and light energy converted into chemical energy due to presence of chlorophyll.

Therefore,During the process of photosynthesis plants convert light energy into chemical energy and can be stored in the molecular bonds of organic molecules.

Answer:

Epigenetic mechanisms control the activity of genes involved in DNA repair pathways and cell growth

Explanation:

Epigenetics can be defined as the study of the alterations in gene expression patterns that do not involve alterations in the DNA sequence. Epigenetic mechanisms include 1-DNA methylation, 2-histone modifications (i.e., methylation, acetylation, phosphorylation, ubiquitination, etc.) and 3-non-coding RNA pathways (microRNAs, long ncRNAs, etc). These epigenetic mechanisms work together to control gene expression patterns by activating or silencing genes at the level of transcription, in a mode that is dependent on the cell type and developmental stage. In consequence, the failure of the epigenetic mechanisms modifies the activity of genes which may be involved in DNA repair pathways and thereby it may lead to severe disorders including some cancers.

Answer:

A. Designing nets that release unwanted species without harming them.

Explanation:

Over-fishing is a negative human practice that leads to the over-exploitation of aquatic ecosystems (i.e., both marine ecosystems and freshwater ecosystems). In an aquatic ecosystem, the communities of organisms coexist in a delicate balance where they are dependent on each other in the food web, providing stability to the whole ecosystem. Therefore, the over-exploitation of any aquatic species is expected to impact the whole ecosystem, thereby also having a negative impact on other fish populations.
