Answer:
The amphipathic property of the phospholipids that constitute the membrane
Explanation:
It seems like a options-based answer so it would be better if they were included here but basically, each of those phospholipid molecules has two parts with antagonistic reactions towards water.
The head is polar or hydrophilic, wich means it can be sorrounded by water. The tail, is apolar or hydrophobic which means it is repelled by water.
The interior and exterior of the cell is contain water-based substances, that's why the heads of the phospholipids are oriented like that with the tails protected inside the membrane.
This double layer structure has a fundamental role in the fluid property of the cell membrane from which derive most of it's functions.
Answer: if i want to breed a rose and i don't have a certain kind of rose, i have to cross between them until i have a kind of rose that express the phenotype i was looking for. Once i've got it, i'll try to cross it with another rose and generate more species like that to cross with the rose that express the phenotype, this favors to generate a specie that have a pure phenotype.
Explanation: The answer is explain by the Mendel's laws.
Mendel's second law:
if you have two roses that are heterozygous and you cross them, their offspring have a 25% probability of generating a homozygous phenotype for a certain recessive characteristic (such as the rich smell of roses that is not a dominant character), 50% of generate heterozygotes with a dominant phenotype, and 25% generate other homozygotes with a dominant phenotype.
Once the offspring with the recessive homozygous character are obtained, it is possible to start making crosses between those of a recessive nature and there Mendel's first law applies
All the homozygous recessive individuals that are crossed will have a 100% homozygous recessive offspring.
Also, if you cross heterozygotes with another heterozygotes the offspring will be 100% heterozygotes
Work is said to be done when an object moves due to a force applied. Work is calculated by multiplying the force applied and the distance traveled due to the force. It is expressed as:
W = Force x distance
W = 84 J = F (7.0 m)
F = 12 N
Hope this answers the question.
Answer:
When making yogurt the tart flavor get in the end is more likely because the bacteria have carried out a type of respiration named lactic acid fermentation (option C).
Explanation:
The process of obtaining yogurt from whole milk involves the association of the bacterial species Streptococcus and Lactobacillus. In order to carry out the lactic acid fermentation that produces yogurt, the bacteria act in a different way:
- Streptococcus is in charge of removing the oxygen from the milk product.
- Lactobacillus promotes the conversion of lactose sugar into lactic acid.
This fermentation process leads to the conversion of milk into a coagulated and tart flavor product.
Other options are not correct because:
<em> A. </em><u><em>Photosynthesis
</em></u><em>: is the process that occurs in plants to obtain chemical energy from sunlight.</em>
<em> B. </em><u><em>Alcoholic fermentation</em></u><em>: in this chemical process alcohol is obtained from the fermentation of a sugar.</em>
<em> D. </em><u><em>Aerobic cellular respiration</em></u><em>: does not involve fermentation, but the series of processes that convert glucose into energy.</em>
Answer:
Phylogenetic trees can be described as diagrams which represents the evolutionary histories of organisms. The organisms that share more common traits or functions are more closer to one another in the diagram.
The phylogenetic tree in the above diagram shows that the ancestors of Danes, Chinese and Tibetans carried the regular EPAS1 alleles.
According to the tree, the Chinese are more closer to the Tibetans as they carry the Tibetan EPAS1 alleles which the Danes do not carry.
