What differentiates Hela cells from other human cells?
Answer:
a normal cell contains 46 chromosomes whereas HeLa cells contain 76 to 80 (ref) total chromosomes, some of which are heavily mutated (22-25), per cell.
Explanation:
The main difference between Hela cells from other human cells is that a normal cell contains 46 chromosomes whereas HeLa cells contain 76 to 80 (ref) total chromosomes, some of which are heavily mutated (22-25), per cell.
What happens when the involvement of hela takes place?The involvement of hela made to the developing field of genetics is a lot was educated about cell reproduction, DNA and mapping genetics. The hela cells prepared them ideal for use in the polio vaccine trials because they were more liable than other cultured cells.
Cancer cells such as Hela cells escape to normal cell cycle by mutations that lead to the misexpression and/or overexpression of regulatory molecules (e.g., cyclins and cyclin-dependent kinases) and faulty checkpoint control of the cell cycle.
The control of the cell cycle depends on 1-cyclins and cyclin-dependent kinases (CDKs) that regulate the cell cycle by a cascade of protein phosphorylations and 2- a group of checkpoint controls that monitor the completion of critical cellular events.
Therefore, The main difference between Hela cells from other human cells is that a normal cell contains 46 chromosomes whereas HeLa cells contain 76 to 80 (ref) total chromosomes, some of which are heavily mutated (22-25), per cell.

Answer:
I don't unerstand the question
Explanation:
I think it's B
Answer:
Tidal power and current power
Explanation:
First, we can determine that A and B are obvoiusly wrong. Ocean thermal energy produces zero carbon emissions, as most forms of hydroelectric power do. Secondly, wave energy might affect aquatic life, but it wouldn't affect the migration of birds. After reviewing the 3rd and 4th answers, they do look reasonable. Therefore, your answer is tidal power and current power.

How are government agencies like the local health department working to keep the public safe from the problem of HAB's?
Answer:
The local health departments work together with local water suppliers and act to monitor harmful algal blooms (HABs)
Explanation:
Harmful algal blooms (HABs) are produced by blooms of algae (phytoplankton), some of them may produce toxins that lead to illness/death in humans and marine organisms (e.g., marine mammals, fish, seabirds, etc). HABs represent a real concern for coastal areas. Cyanobacteria, also known as blue-green algae, may produce HABs both in fresh water and in marine water. Some of the most common causes that may lead to a HAB include the runoff of nutrients (especially those rich in nitrogen and phosphorus), high temperatures, a slow movement of water bodies, etc. The local health departments work to monitor these phenomena by collecting samples in order to analyze the state of the water (i.e., by identifying the presence of toxins, especially cyanotoxins) and give advice to local residents. For these purposes, it is generally required to analyze phytoplankton composition, especially the presence of accessory pigments to chlorophyll a (since these pigments represent good indicators for possible HABs).

If a gene has two alleles, there are two possible genotypes.
a. True
b. False
Answer:
b. False
Explanation:
Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.
Heredity refers to the transfer of traits (specific characteristics) from the parent of a living organism to her offspring through sexual reproduction or asexual production. Some examples of hereditary traits are dimples, tongue rolling, baldness, handedness, freckles, curly hair, color blindness, height, etc.
According to Mendel's Law of Dominance, if a gene has two alleles, there are three (3) possible genotypes.
The three (3) possible genotypes are;
I. A combination of alleles such as AA.
II. A dominant combination (phenotype) such as Aa.
III. A recessive combination such as aa.
Where;
A represents the dominant allelea represents the recessive allele.Also, a single version of a gene expressed by a living organism is referred to as an allele.

Answer:
Explanation:
Weight on a human body is mainly stored as muscle or fat. When we exercise we don't necessarily lose fat. Instead, the fat cells tend to shrink in size but remain the same amount. Fat is converted into energy which the body uses to function. This energy is expelled from the body in many different forms such as carbon dioxide and sweating. Therefore those are the matter that the individual in question lost when losing the 215lbs

What does a Euglena require to exhibit phototactic behavior?
A.
a contractile vacuole
B.
cilia
C.
an eyespot
D.
a pseudopod
Answer:
C
Explanation:
Phototaxis (phototactic response) is the cellular behavior in which cells swim toward or away from the light source. The euglena have eyespots that detect light so that it can move toward sunlight for photosynthesis.
Euglena require an eyespot to exhibit phototactic behavior. Thus option C is correct.
what is phototaxis ?Phototaxis is defined as the movement of an organism in response to external stimulus that means light, it is a locomotory movement of living organisms towards the source of light or away from the source of light.
Taxis means the movement of an organism in response to a stimulus like light or food, it is an innate response of an organism to variation in light intensity and direction.
More is the intensity of light in a particular direction the more will be phototactic stimulation occurs in the organism, its own biological reason and phototactic response are incidental and serve no end purpose.
The advantages of phototaxis are the regulation photosynthesis, the finding of food in phototrophic organisms, facilitation of larval dispersal, or the increased likelihood of gamete fusion on the surface.
Thus option C is correct.

Can someone help me understand interphase, prophase, metaphase, anaphase, and telophase
Answer:
They are all stages of mitosis, which is cell division (for new cells for repair and growth)
interphase- the longest stage of the process. The DNA in the chromosomes copies itself, ready to split for mitosis. ALL 23 pairs copies itself so now there is 46 pairs of chromosomes (23 for each new cell).
prophase- The DNA in the chromosomes are more visible now, and the membrane around the nucleus disappears ready for the next stage
metaphase- Chromosomes and their copies line up in the middle of the cell, so that they could be pulled apart in the next stage
anaphase- Spindle fibres attach themselves to either end of the chromosome. They are then pulled apart to either ends of the cell. 23 on one side, 23 on another.
telophase- membranes form around the 23 pairs of chromosomes at their end of the cell. Two new daughter cells are produced. The cell membrane pinches in and divides the cells in two.

What are the potential advantages and disadvantages of a major shift from the hard or traditional path of energy development to the soft or visionary path?
(These were the corresponding textbook pages, if needed) Please read the following from the textbook Environmental Science:
7th Edition - Chapter 17
9th Edition - Chapter 14
Answer:
Advantages of following the soft path, the argument here is alternative sources of power such as hydropower, geothermal energy , wind energy , and photovoltaic cells must be developed. This provides a alternative source to remain in a healthy environment and also function as the society we currently live in using the hard path. Disadvantages of following the hard path result with future generations fearing over the irreversible damage of climate change and the damage done to our atmosphere. The hard path argue that we should continue to operate in the future as we have in the past, except more efficiently. This is close to impossible and will only continue the negative effects the hard path( the path we have been following) results in. The major shift determines the outcome of this world, the futures worries or reliefs and ultimately the survival of humans.
