Answer:
One of the major disadvantages of 3D cultures is that there is a requirement for the separation of single cells from spheroid structures by proteolytic degradation of single layers, which can take several hours or even a few days. There are many 3D methods where the efficiency, lifespan, repeatability, along with the comfort of work are poorer than in the case of 2D systems, which again is a disadvantage.
Explanation:
3D methods have become a lot more prevalent and are used in the area of cancer research, they can also be applied in tissue engineering. Cell culture is a commonly utilized in vitro tool for expanding our understanding of cell biology, tissue shape, disease mechanisms, medication action, protein production, and tissue engineering development. The majority of cancer biology research is based on in vitro experiments with two-dimensional (2D) cell cultures. However, because 2D cultures have numerous limits, 3D is utilised.

The radiative zone is the outer shell of the sun from which light energy is radiated.
True
False
Answer:
FalseExplanation:
The Radiative Zone is located just beyond the sun's Inner Core, at a distance of 0.25 to 0.7 solar radii. Photon emission and capture by hydrogen and helium ions cause energy to be radiated in this zone.

Think of Earth as a ball with a rod through it, standing for the axis. This makes it easier to imagine Earths orientation in space relative to other objects like the Sun. Now consider the Sun as another ball. Imagine the Sun located in the center of a disk, kind of like a Frisbee. The planets in the solar system would be positioned on the Frisbee but at varying distances from the Sun. The area we are imagining as a Frisbee is actually called the plane of the ecliptic. It is the plane of Earths orbit around the Sun. Earths axis is not oriented perpendicular to the plane of its orbit. It is tilted at 23.5 degrees from the perpendicular. Why is this an important detail? This orientation in space, relative to the Sun, has great influence on Earths seasonal changes.
QUESTION 1
In paragraph 4, what word or phrase gives you a clue to what the word perpendicular means?
Somewhat like a Frisbee
Relative to the Sun

Picture C. where each pair of sister chromatids attaches to a spindle fiber by its centromere.
Picture D. where chromosomes coil up, nuclear membrane breaks down, and spindle fiber system forms.
Answer:
Picture B,
Explanation:
where nuclear membranes form around each set of chromosomes resulting in two nuclei.
The correct option is B. Picture B, where nuclear membranes form around each set of chromosomes resulting in two nuclei.
What is telophase?The last phase of cell division is known as telophase. The nuclear envelopes reform around the fresh nuclei in either half of the dividing cell during telophase.
The nucleus' ribosome-producing regions, or nucleolus, are back. The major components of the spindle apparatus begin to depolymerize as soon as the cell has finished transporting the chromosomes.
The chromosomes dissociate from their tightly bonded structure and return to free chromatin as telophase nears completion. Telophase is terminated by cytokinesis, a process that divides the cell into two new cells.
Therefore, The correct option is B. Picture B, where nuclear membranes form around each set of chromosomes resulting in two nuclei.

Explanation:
A camel is lost in the desert. It is not finding any food or water. It needs 9000 kilo calorie energy and 4 litre water daily. Its mass is 650 kg and 10% of its mass is fat. It has a water reservoir near its neck with a reserve of 312 litre water. It can live using its fat storage. 1g fat contains 9 kilo calorie energy. How long the camel can survive with it's reserve?
The correct answer to how long the camel can survive with its reserve would be 65 days.
First, let us calculate the total amount of energy derivable from the fat in the body of the animal:
Mass of the camel = 650 kgMass of fat = 10% of the total mass= 10% x 650 = 65 kg
If 1g of fat is equivalent to 9000 kilocalories of energy in the animal, then, 65 kg of fat would be equivalent to:
65 x 1000 x 9000 = 585,000 kilocalories of energyThe total amount of energy is 585,000 kilocalories and the total amount of reserved water is 312 litres:
Amount of energy required per day = 9000 kilocaloriesNumber of days 585,000 kilocalories of energy can serve = 585,000/9000= 65 days
Amount of water needed per day = 4 litresNumber of days 312 litres of water can serve = 312/4= 78 days
The water reserve can last 78 days while the energy reserve can last 65 days. Since the camel needs both to survive, it means the animal can only survive for 65 days.
