Answer:

t

Explanation:

While Glycolysis and the Citric Acid Cycle make the necessary precursors, the electron transport chain is where a majority of the ATP is created. The Electron Transport Chain makes energy ... At the end of the chain the electrons are taken up by oxygen molecules to make water. This is why oxygen is known as the final electron acceptor.

Answer:

Explanation:

during electron transport, energy is used to pump hydrogen ions across the mitochondrial inner membrane, from the matrix into the intermembrane space. A chemiosmotic gradient causes hydrogen ions to flow back across the mitochondrial membrane into the matrix through ATP synthase, producing ATP

Answer: The answer is D

Explanation:

The statement which is true about the structure of organic molecules is as follows:

Thus, the correct option for this question is D.

Organic molecules may be defined as those molecules that are correspondingly made of carbon and hydrogen. It can also include other elements like oxygen, sulfur, nitrogen, etc. It must contain carbon atoms covalently bonded to hydrogen atoms (C-H bonds).

DNA possesses monomeric units known as nucleotides. Lipids are the derivatives of fatty acids. While proteins are composed of building blocks that are known as amino acids.

On the other hand, carbohydrates are derived from monosaccharide units that are togetherly held by glycosidic linkage.

Therefore, carbohydrates contain monosaccharide units is a statement that is true about the structure of organic molecules. Thus, the correct option for this question is D.

Answer:

Have cones as reproductive structures.

Have vascular tissue.

Explanation:

The gymnosperms have vascular tissue and have cones as reproductive structures.

The gymnosperms are woody like plants having a  cone shaped structure,  bear no flowers, no fruits but bear seeds; The seeds are with out coat and they are not covered by the fruit wall.

Gymnosperms produce seeds which are not enclosed in an ovary, while in Angiosperms the reproductive organs are the flower, they may  involve in double fertilization resulting in a diploid zygote, and a triploid endosperm.

Gymnosperms  produce seeds and fruits from their flowers, the flowers in gymnosperms helped in the propagation of the plants, it attract pollinators and attracted seed to dispersers, gymnosperms became dominant among plants.

The modification of the gymnosperm includes Modified leaves, Sunken stomata, Pointed and thick cuticle leaves, Less transpiration rate.

The company's decision against using hydroelectric Energy as an alternative energy source might be Gathering it can have a negative affect on natural habitats.

Hydropower can also cause environmental and social problems. Waterholes drastically change the landscape and rivers they are built on. Dams and reservoirs can decrease river flows, raise the water temperature, degrade water quality and cause sediment to build up. This has negative impacts on fish, birds and other wildlife.

Thus, the correct option is "D".

Field study

Explanation:

I took the quiz and got it right. Hope this helps :)

The type of research method that would best answer the given question is field study. The correct option is C.

Field studies are research activities that take place outside of your office or lab, in the context of the user.

There are numerous field-study methods and activities to choose from. Field studies also differ significantly in terms of how the researcher interacts (or does not interact) with participants.

Field research is a qualitative research method that involves observing and interacting with people in their natural settings in order to understand and interpret the social interactions of groups of people, communities, and society.

Field studies provide students with first-hand experiences that promote critical thinking, long-term retention, transferability, positive attitudes toward science, appreciation for nature, and increased scientific curiosity.

Field study is the type of research method that would best answer the given question "How many rivers in Florida have nitrate pollution in them?”

Answer:

Natural selection needs some starting material, and that starting material is heritable variation. For natural selection to act on a feature, there must already be variation (differences among individuals) for that feature. Also, the differences have to be heritable, determined by the organisms' genes.

The mitochondrion (/ˌmaɪtəˈkɒndrɪən/, plural mitochondria) is a semi autonomous double-membrane-bound organelle found in most eukaryotic organisms. Some cells in some multicellular organisms may, however, lack mitochondria (for example, mature mammalian red blood cells). A number of unicellular organisms, such as microsporidia, parabasalids, and diplomonads, have also reduced or transformed their mitochondria into other structures.

Answer:

If a pine seed finds the right micro-climate, it will eventually sprout and a pine seedling will start to grow. However, pine seeds are usually released in a dormant state, which is most often broken by cold stratification. As a result, a pine seed will not sprout until the following spring when warm weather and some spring moisture are present.

mRNA and then amino acids

Explanation:

Codons are triplets (3) bases that code for defined amino acid sequences.

DNA is transcribed into mRNA. The mRNA codons are then translated into amino acid chains that form proteins.

Each codon codes for an amino acid, which is brought to the growing polypeptide chain by tRNAs via complementary base pairing.

Answer:

Muttation can occur during the exchange of genetic meterial from homologous chromosomes which may led to cause deseases in some cases.

Explanation:

Homologous chromosomes exchange genetic material during the process of meiosis.

Meiosis is a type of cell division in which germ cells present in the sexually-reproducing organisms produces the gametes, such as sperm or egg cells. It involves two rounds of division which results in four cells with only one copy of each chromosome.

These four cells are haploid in nature. Meiosis produces the sex cells or gametes like eggs in females and sperm in males.

Meiosis is divided into nine stages. These are divided between the first time the cell divides (meiosis I) and the second time it divides (meiosis II).

Thus, homologous chromosomes exchange genetic material during the process of meiosis.
