Answer:
Biomass
Explanation:
In most cases, it is organic waste. anything, including pig intestines, maize husks, and wood chips. The procedure can vary depending on what is burned specifically, but in a typical power plant arrangement, it is burned similarly to coal. Pollution (even if it is carbon neutral) and the plant's potential for intermittent feedstock supply, which reduces efficiency, are downsides. either carbon neutral or renewable In my opinion, it is renewable by definition. Although it is not carbon neutral, very little else is either. Solar and wind energy still have a carbon impact. Those still have a net gain even though they offset more carbon than their footprint (per current manufacturing). Although burning biomass has a positive carbon footprint, is it more carbon-neutral than burning coal and natural gas? Maybe. Burning biomass releases carbon dioxide into the atmosphere that has previously been stored. Through feedback processes, this sudden rise in carbon will lead to an increase in other GHGs. Cutting down young trees for this reason also eliminates a carbon sink, which doesn't replenish until 60+ years (or 100+ in certain cases). Other biomass sources have a quicker recovery time. It is possible for biomass to be net negative when combined with carbon capture. Its efficiency might be increased by using it directly for heating purposes. There are several factors to take into account while deciding whether to utilize it, such as which other sources it would actually counteract. Overall, it should be used sparingly and with continual consideration of the particulars.

Answer:
Explanation:
1. The genotype is Ff for both
2 The phenotype is having freckles
3. FF, Ff, Ff, ff
4. 75% freckles 25% no freckles
Answer:
1.) Genotype = Ff
2.) Phenotype = having freckles
3.) Possible Genotypes = FF, Ff, ff
Probability of each Genotype = 25% FF, 50% Ff, and 25% ff
4.) Possible Phenotypes = Freckles and no freckles
Probability of each Phenotype = 75% freckles and 25% no freckles
Explanation:
1.) A genotype is the specific combination of alleles which give rise to a trait. Alleles are represented by the letters (F and f).
Heterozygous individuals have one of each type of allele. Therefore, the genotype of the couple is Ff.
2.) Phenotypes are the trait which the genotypes are expressing. When an allele is said to be dominant (like the F allele), it means that individuals with at least one of these alleles will express the associated trait. Remember, heterozygous individuals have one dominant allele (F) and one recessive allele (f). Because there is at least one dominant allele, the phenotype of the couple is to have freckles.

compare and contrast sexual and asexual reporduction
Difference:
The biological process of sexual reproduction requires the input of genetic material from many people. When a flower self-pollinates, for example, the term "individual" might refer to gamete cells developing as a single physical or even genetic organism. I don't want to substitute the word "cell" for "person," either, as that would eliminate instances of acellular biologic entities that reproduce, like viruses. When a piece of a chromosome from one bacterium is injected into another, it recombines and reproduces there, with or without sporulation, which is one instance of what I consider sexual reproduction but which not all viewers would. My notion just requires some genetic material, even in the form of an episome, not gametes. Asexual phases are included in nearly all forms of reproduction, but I regard all of them to be a part of sexual reproduction when they take place throughout a life cycle that also contains an obligatory sexual phase. Brewer's yeast serves as an illustration of the distinction I make because either the diploid or haploid stage, which could be classified as a gametophyte or sporophyte, can be maintained through an infinite number of mitoses. As a result, I consider vegetative propagation to be asexual reproduction.
Now that you have the difference compare the similarties.

Place a check mark next to each star that is only fusing hydrogen into helium at this time.
The stars that are only fusing hydrogen into helium at this time are :
Star 1 Star 2 and Star 3 Characteristic of a star fusing hydrogen into heliumA star fusing hydrogen into helium is categorised as a main sequence star. As a star continues to fuse hydrogen into helium, energy is released in the process and the luminosity of the star increases as well. An example of a star that has completely fused hydrogen into helium is the sun. A giant red star signifies that the star is out of hydrogen it uses for nuclear fusion.
Hence we can conclude that the stars undergoing hydrogen fusion into helium are stars 1, 2 and 3

Why are chloroplasts more on one side of a cell than the other
You would be referring to the plant cell.
Answer:
Chloroplasts may be seen on all six sides of a plant cell, which is a three-dimensional entity with typically moderately rounded corners (not in the centre because a big central vacuole fills a very large part of the volume). Chloroplasts are constantly being rearranged by the cell since they are not set in place. Chloroplasts are typically located close to so-called periclinal cell walls, which are oriented in the same 2D orientation as the leaf surface under low light. Chloroplasts seem to "escape" to the anticlinal walls in bright light. Better light harvesting in low light by exposing every chloroplast to light and photoprotection by mutual shading in strong light are likely the fitness benefits provided by this behavior. In the dark, chloroplasts also gravitate toward the anticlinal walls. Thin leaves of submerged aquatic plants like Elodea can be used as microscope specimens to observe chloroplast motions. One can gauge how much light gets through a leaf in land plants. What I just said concerning the top layer(s) of leaves' "palisade parenchyma cells" is accurate. Most of the chloroplasts are found in these cells. Numerous cells in the spongy parenchyma under the palisade layer lack well marked peri and anticlinal walls.
How did plant cells incorporate chloroplasts in their DNA?
Chloroplasts must reproduce in a manner akin to that of some bacterial species, in which the chloroplast DNA is duplicated first, followed by binary fission of the organelle (a kind of protein band that constricts so that two daughter organelles bud off). As a result of some chloroplast DNA actually being integrated into the plant genome (a process known as endosymbiotic gene transfer), it is now controlled in the nucleus of the plant cell itself.
Based on the model simulation of the carbon cycle, what happens when you increase the plant biomass?
Atmosphereic co2 decreases
Atmospbereic co2 stays the same
Atmospheric co2 increases
Based on the carbon cycle simulation model, what happens when you increase plant biomass is that atmospheric CO2 decreases. because in the cellular respiration of the plants they will consume more carbon.
How do plants influence the carbon cycle?Plants, through the process of respiration, also absorb carbon dioxide and release oxygen unlike animals. The carbon deposited in the soil can undergo alterations, turning into fossil fuels such as oil and natural gas, in addition to forming diamonds, graphite and coal mines, among others.
With this information, we can conclude that based on the carbon cycle simulation model, what happens when you increase plant biomass is that atmospheric CO2 decreases. because in the cellular respiration of the plants they will consume more carbon.

Changes in water temperature affect the density of the water. Water density is important for deep ocean currents that move water around the oceans. With increasing greenhouse gases in the atmosphere, the ocean is absorbing more and more heat. The Beaufort Gyre is a circular current in the Arctic. Which of the following is the most reasonable hypothesis as to what would happen to the Beaufort Gyre if the oceans keep warming?
The water would get warmer and would not sink to the bottom, and therefore disrupt the worldwide currents.
The water would get colder and sink to the bottom, then take longer to warm up disrupting currents.
The water would change temperature and begin to circulate in the opposite direction.
The water would get much warmer and cause part of any nearby continental ice sheet to melt.
Answer:
The water would get warmer and would not sink to the bottom, and therefore disrupt the worldwide currents
Explanation:
the warmer water is less dense than the colder water and would not sink, which would interrupt the natural currents with extra external heat added by global warming
how does carbon dioxide affect the ecosystem
As a greenhouse gas that absorbs heat, CO2 raises the temperature of the atmosphere. We refer to this as global warming. The glaciers will melt more quickly as the world's temperature rises, raising sea levels and bringing on disaster. More power is consumed for air conditioning as the temperature rises, which further raises the air's CO2 level.
Since coal is the primary fuel utilized in the creation of power. This creates a vicious cycle.
