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.

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:

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.

Explanation:

Answer:

C broken down into amino acids.

Explanation:

Proteins are one of the four major biological molecules. They are organic polymers made up of monomers called AMINO ACIDS. Proteins are contained in food we ingest and are subsequently digested or broken down into their amino acid components.

In this case, when a person eats yogurt (containing proteins), the 14 grams of protein will be broken down into amino acids during digestion by enzymes called PROTEASES. Note that every polymer will be broken down into its monomeric constituents during digestion.

Direct effects, as the name suggests, while not manipulated or communicated by a third party, deal with the direct influence of one entity on another. Indirect effects can be described as the influence, mediated or passed on by a third, of one organism or species on another.

Answer:

D)NADPH is made

A)ATP is used

Explanation:

Sorry to ask the two questions, I asked why the two options are in the process:Reduction. In the second stage, ATP and NADPH are used to convert the 3-PGA molecules into three-carbon sugar molecules, glyceraldehyde-3-phosphate ( G3P ). At this stage, it gets its name because NADPH donates, or reduces , electrons to a three-carbon intermediate to form G3P.[Ocultar detalhes]

The reduction stage of the Calvin cycle, which needs ATP and NADPH, converts 3-PGA (produced in the fixation stage) into a three-carbon sugar. This process takes place in two main stages:

Simplified diagram of the reduction step of the Calvin cycle showing the carbon atoms, but not the complete molecular structures. A 3-PGA molecule first receives a second phosphate group from ATP (generating ADP). Then, the doubly phosphorylated molecule receives electrons from NADPH and is reduced to form glyceraldehyde-3-phosphate. This reaction generates NADP + and also releases an inorganic phosphate.

A 3-PGA molecule first receives a second phosphate group from ATP (generating ADP). Then, the doubly phosphorylated molecule receives electrons from NADPH and is reduced to form glyceraldehyde-3-phosphate. This reaction generates NADP + and also releases an inorganic phosphate.

First, each 3-PGA molecule receives a phosphate group from ATP, becoming a doubly phosphorylated molecule called 1,3-bisphosphoglyceride (and leaving an ADP as a by-product).

Second, 1,3-bisphosphoglycerate molecules are reduced (gain electrons). Each molecule receives two electrons from NADPH and loses one of its phosphate groups, becoming a three-carbon sugar called glyceraldehyde-3-phosphate (G3P) . This step produces NADP^+

The ATP and NADPH used in these steps are products of the photo-dependent reactions (first stage of photosynthesis). That is, the chemical energy of ATP and the reducing potential of NADPH, both produced with the use of light energy, keep the Calvin cycle running. Conversely, the Calvin cycle regenerates ADP and NADP^+

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.

Some bacteria are good for you, including the bacteria in your digestive system, or gut. These bacteria help to break down food and keep you healthy. Other good bacteria can produce oxygen are used to create antibiotics. Bacteria are used in food production to make yogurt and fermented foods.

An example of how Eubacteria can be beneficial is that these bacteria fix nitrogen for soil that can be used by living beings.

The bacteria in your gut and digestive tract are among the beneficial bacteria. These microorganisms aid in the digestion of food and promote good health. To make antibiotics, other beneficial microorganisms that can also produce oxygen are employed. Yogurt and other fermented foods are produced using bacteria in the food industry.

Oxygen, carbon, nitrogen, and phosphorus that living things like animals and plants cannot use can be converted by eubacteria into usable forms. In the soil, they fix the nitrogen that is present in the air.

Therefore,  Eubacteria can help the environment by fixing nitrogen into the soil so that living things can use it.

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.

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.
