If mammalian cells receive a go-ahead signal at the G1 checkpoint, they will complete the cell cycle and divide normally.

The cell cycle may be defined as the entire sequence of events happening from the end of one nuclear division to the beginning of the next nuclear division.

There are three major checkpoints in the cell cycle. One at the end of the G1 phase, the second at the end of the G2 phase, and while third is during the M phase.

Therefore, if mammalian cells receive a go-ahead signal at the G1 checkpoint, they will complete the cell cycle and divide normally.

Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment.

The three steps that are required for DNA  replication are initiation, elongation and termination.

The process in which DNA of a cell under go duplication to produce two copies during S-phase of cell cycle called as DNA replication.

It involves 3 steps such as initiation step where the origin of replication of DNA molecule undergo unwinding into two DNA strands.

An incomplete unzipping by forming replication fork is created is catalyzed by the helicase enzyme.

Secondly in elongation step the DNA polymerase enzymes make the complementary sequence against each parent template strand.  

It is an unidirectional, one strand which is synthesized in a continuous manner called leading strand, the strand which is synthesized in a discontinuous manner called lagging strand with Okazaki fragments.

Termination occurs in the last step, when the parent molecule has been completely replicated.

Answer:

Sedimentary.

Explanation:

Sedimentary will determine if water temperature affects the weathering of sedimentary rocks.

Mendel concluded that the alternative forms of each trait are coded by discrete factors, which were called alleles that combine in pairs to express the trait. Traits are inherited in discrete units and are not the result of "blending."

------------------------

After making many crosses that involved different traits -such as plant height, or flower colors-, Mendel observed that, per trait, the F1 only expressed one of the alternative forms, while de other one disappeared.

Mendel named dominant the expressed variant.

Mendel then let these new plants auto pollinate and observed the results in the second generation, F2.

He saw that the variants that had previously disappeared among the F1, reappeared again. Both alternatives for each trait were present in the F2.

Mendel named recessive the second alternative variant.

Mendel explained his results by arguing that discrete factors were responsible for these phenotypes.

Mendel conclusion about his experiments was that per trait -flower color of plant length-, each plant had a pair of factors -which he named alleles-, and that each factor coded for one of the alternative forms of the traits -white or purple, tall or short-.

He thought that alleles separate -segregate- during the process of gamete formation.

The First Mendel's Law is the first conclusion he took about his experiments and is known as the segregation principle.

Answer:

To spread carbon dioxide and oxygen.

Explanation:

Plants produce carbon dioxide and oxygen. This is called photosynthesis.

Answer:

Chlorophyll gives plants their green color because it does not absorb the green wavelengths of white light. That particular light wavelength is reflected from the plant, so it appears green. Plants that use photosynthesis to make their own food are called autotrophs.

Answer:

A. absorbs green light

B. reflects green light

C. emits green light

ANSWER: B. reflects green light

Explanation:

our eyes can only see what objects reflect, so if it's appearing green then obviously it's reflecting the green light.

Rocks from the Ordovician Period contain evidence that plants began colonizing dry land at this time. Most experts agree that the ancestors of land plants first evolved in a marine environment, then moved into a freshwater environment and finally onto land.

Ordovician Period, in geologic time, the second period of the Paleozoic Era. It began 485.4 million years ago, following the Cambrian Period, and ended 443.8 million years ago, when the Silurian Period began. Ordovician rocks have the distinction of occurring at the highest elevation on Earth—the top of Mount Everest.

Answer:

Finally, the number of times the pile is turned influences composting speed. By turning more frequently (about every 2-4 weeks), you will produce compost more quickly. Waiting at least two weeks allows the center of the pile to heat up and promotes maximum bacterial activity. The average composter turns the pile every 4-5 weeks.

When turning the compost pile, make sure that materials in the center are brought to the outsides, and that materials from the outside edges are brought to the center.

With frequent turning, compost can be ready in about 3 months, depending on the time of year. In winter, the activity of the bacteria slows, and it is recommended that you stop turning the pile after November to keep heat from escaping the pile's center. In summer, warm temperatures encourage bacterial activity and the composting process is quicker

Using compost in the yard

Incorporate compost into your garden as you prepare the soil in the spring. Cover the area with 3-4 inches of soil and till it in to at least the upper 6 inches of soil. Add compost to soil in vegetable gardens, annual flower beds, and around new perennials as they are planted.

You may also use compost as mulch around flower beds, vegetable gardens, or around trees or shrubs in landscape beds. Apply a 3 inch layer. Be careful not to apply mulch close to the main stem or trunk of the plant.

Water moves through the xylem in a stream called a transpiration stream, up to the leaves of the plant. Sugar is made during the process of photosynthesis. Unlike water and ions, it travels through the plant via the phloem, moving up and down through the plant.

Answer:After the energy from the sun is converted and packaged into ATP and NADPH, the cell has the fuel needed to build food in the form of carbohydrate molecules. The carbohydrate molecules made will have a backbone of carbon atoms. Where does the carbon come from? The carbon atoms used to build carbohydrate molecules comes from carbon dioxide, the gas that animals exhale with each breath. The Calvin cycle is the term used for the reactions of photosynthesis that use the energy stored by the light-dependent reactions to form glucose and other carbohydrate molecules.

Explanation:The Interworkings of the Calvin Cycle

In plants, carbon dioxide (CO2) enters the chloroplast through the stomata and diffuses into the stroma of the chloroplast—the site of the Calvin cycle reactions where sugar is synthesized. The reactions are named after the scientist who discovered them, and reference the fact that the reactions function as a cycle. Others call it the Calvin-Benson cycle to include the name of another scientist involved in its discovery (Figure 5.14).

This illustration shows that ATP and NADPH produced in the light reactions are used in the Calvin cycle to make sugar.

The axonal membrane (place as brainliest so others know its correct)

Receptors for neurotransmitters are of primary functional importance in assuring one-way synaptic transmission because they are mostly found on the Axonal membrane.

Neurotransmitters may be defined as the type of chemical substances that are correspondingly liberated at the end of a nerve fiber by the arrival of a nerve impulse and, by diffusing across the synapse or junction. They are released in the location known as the synaptic cleft.

The receptors of these neurotransmitters are present in the plasma membrane of postsynaptic cells which selectively bind the transmitter. They are integral membrane glycoproteins with multiple transmembrane segments.

Some examples of neurotransmitters may include serotonin, GABA, dopamine, acetylcholine, etc.

Answer: c

Explanation:because it needs cells I think…

The nutrients from the food get to the cells of the body by the action of two organ systems i.e. the digestive system and the circulatory system.

The digestive system may be defined as a type of organ system that significantly deals with the breakdown of food substances into simpler components that can easily be consumed by the body.

According to the context of the question, the food that we eat reaches the stomach through the esophagus where multiple enzymes perform their roles. After the stomach, the food may be passed to the small intestine which is absorbed here and then the nutrients assimilate in the blood.

Through the blood, the nutrient can be transported around the body by blood from the circulatory system. Thus, the correct option for this question is B.
