Answer:
The correct answer is - The hydrocarbons would become less saturated to increase the fluidity of the membrane
Explanation:
The ratio of saturated and unsaturated fatty acids or hydrocarbon chains is responsible for the membrane fluidity at cold temperatures. Cholesterol is an important part of membrane fluidity as it functions as a buffer, it inserts in phospholipids to preventing lower temperatures from inhibiting fluidity and at higher temperatures stabilizes the cell membrane and increase melting point and prevent increasing fluidity.
Moving from high temperature to low temperature hydrocarbon chains become less saturated in order to increase fluidity as it inserts cholesterols into phospholipids and decrease saturation.
Pietro has two dogs that are related, and he wants to understand why one of the dogs has tan fur and the other has brown fur.
Which pattern of inheritance would explain the different fur color in the related dogs?
Polygenic inheritance is simply a form of inheritance whereby the trait of the individual or the animal is gotten from the cumulative effects of several genes. In such case, there are many genes which control the expression of the trait. This is quite different from the monogenic inheritance whereby the trait is as a result of the expression of just only one gene.
Since Pietro has two dogs that are related, and one of the dogs has tan fur and the other has brown fur, then this means there's more than one gene which is expressed in this case.
In conclusion, the answer to the question is polygenic inheritance.

b. Banana and lemon
c. Onion and radish
d. Banana and onion
Based on the model, Banana and lemon are the pairs of species most likely have the greatest number of differences in their DNA and protein sequences. Thus, option B is correct.
What is DNA?
DNA contains the genetic information needed to determine the structure and function of living organisms. Each DNA molecule is found on a chromosome, and the segments of that DNA molecule are genes.
In somatic cells -such as nerve and muscle cells- the DNA sequences are the same, but what determines the synthesis of different proteins is the information that the genes have, i.e., fragments of DNA contained in a cell.
For this reason, nerve cells have a gene that allows them to synthesize the enzyme cholinesterase, while muscle cells have a gene that codes for myosin, even though they both possess the same DNA sequence.
Therefore, Based on the model, Banana and lemon are the pairs of species most likely have the greatest number of differences in their DNA and protein sequences. Thus, option B is correct.

Describe TWO environmental consequences, other than those related to the loss of boreal forest habitat, that result from the extraction of bitumen or the transportation of synthetic oil to customers.
Answer: The greenhouse gas emissions from the extraction of bitumen and the use of large quantities of water.
Explanation:
Bitumen is a natural flammable organic matter formed from kerogen in the process of petroleum generation, which is soluble in carbon disulfide. Asphalt and mineral wax are examples of hydrocarbons which are part of bitumen. Conventional oil is extracted by wells while oil sands deposits are extracted using surface mining sectioning techniques, or are flowed to wells by in situ techniques that reduce bitumen viscosity by steam and/or solvents. So, unlike crude oil extracted in oil wells, bitumen requires an open-pit mining operation, in which large tracts are washed with a mixture of water and chemicals to separate the bitumen from a mixture of sand and clay.
Two consequences of this practice are:
The greenhouse gas emissions from the extraction of bitumen are larger than the extraction of conventional oil. The emissions produced contribute to enhance the greenhouse effect and cause global warming. The greenhouse effect occurs when certain gases retain part of the energy emitted by the earth's soil when heated by the sun's radiation. This phenomenon occurs naturally, and thanks to it, the average temperature of the Earth is about 14º C (57.2 °F). The problem occurs when these greenhouse gases increase in the atmosphere and the amount of energy that is not released into space also increases and, with it, the Earth's temperature. The extraction of bitumen from oil sands requires the use of large quantities of water, and even though water used here can be recycled, only a small amounts is returned to the natural cycle. Also, spills from the transportation of the oil could damage soils and waterways, increasing water pollution. This toxic water could get into surface.The rising of bread dough is the result of The rising of bread dough is the result of oxygen being released. carbon dioxide produced by fermentation. biotin production. oxidative phosphorylation.

what is photosynthesis
Answer:
Photosynthesis is a process by which phototrophs convert light energy into chemical energy, which is later used to fuel cellular activities. The chemical energy is stored in the form of sugars, which are created from water and carbon dioxide.
Hey there!
Photosynthesis is the reaction that converts light energy to chemical energy in sugar and carbohydrates. Humans can't eat sunlight, so we eat plants. Plants convert the energy in the sunlight into chemical energy using chlorophyll. Chlorophyll is a molecule produced by plants, algae, and cyanobacteria, which aids in the conversion of light energy into chemical bonds. It is the green pigment found in the chloroplasts of higher plants. They are a part of our ecosystem, and they are lower on the food chain.

Why do organisms need both mitosis and meiosis to process?
Explanation:
Both mitosis and meiosis processes are extremely important because they are the division of chromosomes and without this division reproduction would not occur. Cell division plays an important role in the life cycle of a cell allowing the cell to grow, develop and then reproduce.
Mitosis and meiosis are cell divisions that are needed by organisms because of its importance to them.
Mitosis is a type of cell division where by a single cell divides to form two identical daughter cells.
The importance of mitosis to organisms include:
They help in repairing the damaged cells,They help in growth and development of organisms.Meiosis is a type of cell division where by a single cell divides two times to produce four cells.
These four cells contain half the original amount of genetic information of the divided cell.
The importance of meiosis to organisms include:

In meiosis II, _____. View Available Hint(s) In meiosis II, _____. chromosomes cross over to exchange genetic information chromosome number is reduced from diploid to haploid homologous chromosomes pair to ensure their even distribution to daughter cells sister chromatids are separated
Answer:
The correct answer is - sister chromatids are separated.
Explanation:
Meiosis is divided in two parts meiosis I and meiosis II. In the later part that is meiosis II is characterized by forming four haploid gametes by separating the sister chromatids in the two daughter cell.
Crossing over takes place in meiosis I that leads to recombination and reduces the chromosome number from diploid to haploid homologous chromosomes and then enters into meiosis II.
