What do you think would happen to the process of cell division if there is a deficiency in the Golgi apparatus's ability to package protein tubule materials?
Answer:
The process of cell division will slow down and the cell will die
Explanation:
Without the golgi apparatus or if its not working as well as it should be there would be no lysosomes or less. Without the lysosomes there will be a lot of junk/trash in the cell and it would have no way to break it down and get it out
Explain what are ethics.

discuss the role of cell turgor to plants
Answer:
Turgor potential or pressure is potential also known as pressure potential takes place in a plant cell that exerts pressure on the walls of the plant cell due to the movement of water through osmosis.
Role of cell turgor:
1. regulates the shape of the cell.
2. It provides rigidity for the structure of cells
3. High turgor pressure opens stomatal pore low turgor pressure closes the stomata.
4. support to soft tissues like the parenchyma.
5. keeps leaves oriented to the surface available to light.

Which statement would be used in an argument against the use of human embryonic stem cells for therapy? A.Obtaining embryonic stem cells for use in therapy requires the destruction of embryos. B.Embryonic stem cells are limited in their ability to become different types of cells. C.It is difficult to grow embryonic stem cells in laboratory cultures, so they are not a practical choice for stem cell therapy. D.Embryonic stem cells originate in plants, so the likelihood of rejection by a patient's body is high.
Answer:
A.Obtaining embryonic stem cells for use in therapy requires the destruction of embryos.
Explanation:
Research involving human embryonic stem cells is subject to ethical and political debate because these investigations involve the destruction of human embryos. Stem cells have a series of advantages in the field of organ/tissue regeneration, to investigate the etiology of degenerative diseases, therapeutic cell cloning, etc. However, in many countries, the moment where life begins is a controversial point, and therefore this issue must be defined clearly before research.
The statement, that is, obtaining stem cells for utilization in therapy requires the destruction of embryos would be an argument against the use of human embryonic stem cells for therapy.
These are the pluripotent stem cells obtained from the inner cell mass of a blastocyst, that is, an initial stage pre-implantation embryo.
Research on human embryonic stem cells is subject to political and ethical debate, as these researches comprise the destruction and killing of human embryos. In the field of organ or tissue regeneration, the stem cells possesses an array of merits, they can play an essential role in therapeutic cell cloning, and to determine the etiology of degenerative disease.
But in many countries, the instance when the beginning of life has taken place is an ethical issue, thus, there is a requirement of clearly defining the issue prior to performing any kind of research.
Thus, the correct answer is option A.

What do I put in the chart? Picture attached
Answer:
The woman's genotype - Bb
The man's genotype - bb
Chances of having a child with blue eyes - 50%
Chances of having a child with brown eyes - 50%
Explanation:
Many of our traits are determined by our genetics. We inherit genetic information from both of our parents. From each of them, we get one copy of a gene that determines a certain trait. These gene copies are called alleles.
The dominant allele is the one that masks the effect of the other type of allele, called the recessive allele. This means that a person needs to have only one dominant allele in order for its effect to be expressed. In order for the effect of the recessive allele to be expressed, the person needs to have two recessive alleles.
If a man has blue eyes, which is a recessive trait, he needs to have two recessive alleles (bb). This is why the genotype of the man is bb.
If his child has blue eyes, this means that its genotype is bb as well. The mother's eyes are brown, which means that she needs to have at least one recessive allele. Based on this, we can conclude that her genotype is Bb.
Since the mother has one dominant allele, this means that her children could have brown eyes as well. This is what the Punnett square would look like:
B b
b Bb bb
b Bb bb
Two out of four children would have brown eyes, and the other two would have blue eyes. This means that their chances of them having a child with blue eyes are 50%. The chances of them having a child with brown eyes are the same.
How did Mendel’s results from dihybrid crosses help him develop the law of independent assortment?
Explanation:
The out come that mendel's observed from dihybrid crosses confirmed that each trait could be described by a pair of factors that segregated to form progeny (his first law) and further suggested that factors for multiple traits segregated independently, thus forming the basis for mendel's second law of inheritance
Hope this will help you analyse your answer
Mendel crossed plants with two different features. He proposed the Law of Independent Assortment because the ratio showed that the inheritance of one trait is independent of the inheritance of another.
Mendel conducted studies to investigate the simultaneous inheritance of two distinct features, such as seed color and seed texture.
He combined plants that were different in both qualities, for example, a plant with smooth texture and yellow seeds crossed with a plant with wrinkled texture and green seeds.
The qualities Mendel was seeing separated independently of one another, indicating that the inheritance of one feature did not affect the inheritance of the other.
In other words, during gamete production, the alleles for seed colour and seed texture were assorting separately.
Thus, Mendel proposed the law of independent assortment, which is one of the cornerstones of inheritance, as a result of his dihybrid crosses and the observation of independent segregation of characteristics.

Single-celled pond organisms have contractile vacuoles that maintain water balance within each cell. This is a an example of what scientific principle?
Answer:
The correct answer is homeostasis.
Explanation:
A self-regulating procedure taking place within an organism, which permits them to sustain a stable internal condition level is termed as homeostasis. In case, if an organism fails to sustain homeostatic balance, the eventual result would be death. Water balance, temperature, salt concentration, and pH are some of the several internal conditions, which are required to maintain comparatively stability.
Some of the single-celled pond organisms like paramecium comprise contractile vacuoles, which remove additional water out of the cell. As water balance is a part of sustaining homeostatic balance for an organism, thus one can study homeostasis by witnessing the modifications within the contractile vacuole when the species is placed in distinct solutions.

Explanation:
summarize the process of the water cycle.
Answer:
Earth's water is always in movement, and the natural water cycle, also known as the hydrologic cycle, describes the continuous movement of water on, above, and below the surface of the Earth. The hydrologic cycle begins with the evaporation of water from the surface of the ocean. As moist air is lifted, it cools and water vapor condenses to form clouds. Moisture is transported around the globe until it returns to the surface as precipitation. Groundwater either seeps its way to into the oceans, rivers, and streams, or is released back into the atmosphere through transpiration. The balance of water that remains on the earth's surface is runoff, which empties into lakes, rivers and streams and is carried back to the oceans, where the cycle begins again.

What is photosynthesis?Plants absorb water and carbon dioxide from the soil and atmosphere during photosynthesis. Water is oxidized, which means it loses electrons, while carbon dioxide is reduced, which means it receives electrons, inside the plant cell.
Water is converted into oxygen and carbon dioxide into glucose as a result. After storing energy within the glucose molecules, the plant releases the oxygen back into the atmosphere.
The process by which plants convert carbon dioxide, water, and sunshine into oxygen and sugar-based energy is known as photosynthesis.
Therefore, light energy where you have it and Move glucose to where carbon dioxide is and Move carbon dioxide to where glucose.

You notice that a group of students went on a hiking trip to Cockscomb basin. They are asked to climb a hill, by the time they reach the top of the hill some of them are almost out of breath, while others don't even make it to the top of the hill. Only a few seem not to be affected much by the climb. Plan and design an experiment in which you offer a possible explanation for the differences in breathing rate.
Answer:
It depends on the stamina of the individual.
Explanation:
The possible explanation for the differences in breathing rate is related to the daily activities of the individuals. For example, if the daily activities of the people are hard so it has big stamina and experience no difficulty in the climbing of a hill while those people who has little hard daily activities have low stamina and their breathing rates increases while climbing a hill. Where as those people who perform no daily activities have no stamina and will be unable to climb on the hill.

Skeletal Adaptations. Giraffes, lizards, and many other known species adapted to their environments through genetic changes to their skeletons. Coloration. Many species have been studied who've adapted to their environment through adaptions in coloring. Natural selection is the process in nature by which organisms better adapted to their environment tend to survive and reproduce more than those less adapted to their environment. For example, treefrogs are sometimes eaten by snakes and birds. However, natural selection does not always go to the optimum. An example of variation is that I have a cat with black fur and one with yellow fur. Trait that can be PASSED DOWN to offspring through genes.

There are two major ways that molecules can be moved across a membrane, and ... is trying to be evenly distributed everywhere, like dropping food coloring in water. ... These channels are almost always specific for either a certain molecule or a ... When a molecule moves down its concentration gradient is it participating.
When a solute particle from the region of high concentration travels towards the region containing the lower solute particle is called passive transport. It is transported easily without spending energy.
Bacteria ensures that the food molecule from the surrounding will transport through the passive transport system by the concentration gradient as molecules can get in the cell by two processes.
Concentration gradient allows the movement of food from the region of high concentration towards the region of low concentration that is in the bacterial cells.
Bacterial membrane permits the movement of food molecules across its membrane easily.
