The modern order Squamata likely descended from the fossil reptile group____.
Answers
The modern order Squamata, which includes lizards and snakes, likely descended from the fossil reptile group known as the "diapsids."
Diapsids were a diverse group of reptiles that emerged during the late Paleozoic era. They were characterized by having two openings on each side of their skulls, known as temporal fenestrae.
Over time, the diapsids diversified into various lineages, including the archosaurs (which gave rise to dinosaurs and birds) and the lepidosaurs (which gave rise to modern lizards and snakes). The exact evolutionary lineage from diapsids to Squamata is complex and involves several transitional forms.
However, evidence from fossil records and comparative anatomy supports the idea that Squamata evolved from within the diapsid group, specifically from lepidosaurs, during the Mesozoic era.

Answers
The advantage of using a wet mount is c. the organism is enhanced the specimen can be viewed as living cells
Wet mount are preparations made directly without preservatives containing living objects to be observed. These preparations are usually made by slicing the observation material as thin as possible and then observing it with the addition of water for living cells.
The benefits of wet mount are that they can provide clear results. When the contrast of the specimen is increased by adding water, it will describe a high affinity for cell organelles so that the structure inside will be clearer. Because the structure of the cell organelles is still clearly visible, the specimen can be seen as a living cell which provides more definite observations regarding the structures contained within.

In plant cell cytokinesis, the two daughter cells are separated by the formation of a ______ made from the fusion of ______ vesicles carrying cell wall materials.
Answers
In plant cell cytokinesis, the two daughter cells are separated by the formation of a cell plate made from the fusion of Golgi vesicles carrying cell wall materials.
Cytokinesis is the stage of the cell cycle in which the cytoplasm is divided, producing two separate daughter cells. Cytokinesis occurs immediately after the telophase stage of mitosis (M-phase) and involves the assembly and constriction of an actomyosin contractile ring around the equator of the cell.In animal cells, cytokinesis is achieved through the use of a contractile ring, which constricts the cytoplasm until it is separated into two separate cells. A furrow is formed as the ring constricts, and this furrow eventually deepens until the cell is completely separated into two daughter cells.
However, plant cells undergo cytokinesis differently because they are surrounded by a rigid cell wall that prevents the formation of a contractile ring. Instead, cytokinesis in plant cells is achieved through the use of a cell plate, which forms a new cell wall between the two daughter cells.During cytokinesis, Golgi vesicles move to the middle of the cell and fuse together, forming a cell plate.

Explanation:
Cancer cells:
• Divide uncontrollably
• Comes in many forms
• Invade healthy tissues
• Does not obey contact inhibition
What is cancer?Cancer is a diseased condition in which uncontrolled cell division takes place.
Cancer are of two main types: benign and malignant.
Benign tumours are localized to a particular organ and thus can be removed through chemotherapy or surgery.
Malignant tumours spread to body parts through blood stream and attack the healthy cells. This property of metastasis is unique to cancer cells.
Normal cells show their contact with the adjacent cells. In cancer, contact inhibition is lost and so they divide in an uncontrolled manner.
Breast cancer, leukaemia, lung cancer etc are some of the examples of cancer.
Cancer is detected through tissue biopsy. X-Rays, CT-Scan, MRI are some other techniques that detect cancer in the body.
Cancer can be treated if diagnosed early. Radiotherapy, chemotherapy and surgical intervention are the part of cancer treatment.
Therefore, cancer is considered a serious medical complication.

which process involves antibodies coating microorganisms in order to facilitate phagocytosis?
Answers
The process that involves antibodies coating microorganisms to facilitate phagocytosis is called opsonization.
Opsonization is an immune process in which antibodies bind to the surface of microorganisms, such as bacteria or viruses, marking them for destruction by phagocytes. Antibodies are Y-shaped proteins produced by the immune system in response to the presence of foreign substances.
When antibodies recognize and bind to specific antigens on the surface of microorganisms, they act as opsonins, enhancing the recognition and engulfment of the microorganisms by phagocytes. This coating of antibodies on the microorganisms facilitates phagocytosis, the process by which phagocytes engulf and digest the opsonized microorganisms.

c) Because of its high temperature, a gas shell can be seen as a planetary nebula. After around 50,000 years, the gas cools and stops producing visible light.
When low-mass stars like our Sun run out of fuel and reach the end of their lives, planetary nebulae are created. The star's outer layers are expulsed as it's core disintegrates, leaving behind a shell of ionized gas. Planetary nebulae can be seen in these shells.
However, with time, the planetary nebulae's gas gradually cools and stops producing visible light. After the nebula has cooled down for 50,000 years, it becomes challenging to view.

how are temperature and energy related?
THIS IS SCIENCE
Answers
Answer:
Temperature and energy are closely related in science. Temperature is a measure of the average kinetic energy, or movement, of the particles in a substance. When the particles in an object have more kinetic energy, they move faster and collide more frequently.
As a result, the object's temperature increases. Conversely, when particles have less kinetic energy, they move slower and collide less often, causing the temperature to decrease.
Therefore, temperature can be considered as a way to measure the amount of energy present in a substance, where higher temperatures correspond to greater energy levels.
Answer:
Temperature is a measure of the average kinetic energy of the particles in a substance. Kinetic energy is the energy of motion, and it depends on the speed and mass of the particles. The faster the particles move, the more kinetic energy they have, and the higher the temperature of the substance. The relationship between temperature and energy is also affected by the specific heat capacity of the substance, which is the amount of energy needed to raise the temperature of one gram of the substance by one degree Celsius. Different substances have different specific heat capacities, depending on their molecular structure and interactions. For example, water has a high specific heat capacity, which means it takes a lot of energy to change its temperature, while metals have low specific heat capacities, which means they heat up and cool down quickly.

Imagine you are working with a culture of yeast that is 2 X10^10 cells/ml. You expose the cells to 20
secs of UV light, which you are told results in a 20% survival rate
a. If you plate 0.1 ml from the 10^-6 dilution onto YEPD, how many colonies do you predict to see?
b. If you wanted to have 40 surviving colonies on the plate after the 20 sec UV exposure, how
many cells would you need to plate?
c. What dilution of the culture would you need to plate this number of cells (assuming you plate 0.1 ml)?
Answers
a. If you plate 0.1 ml from the 10^-6 dilution onto YEPD, 4 × 10^11 colonies/ml colonies are predicted to be seen.
b. If you wanted to have 40 surviving colonies on the plate after the 20 sec UV exposure, 1000 cells are needed to be plated.
c. 5 × 10^-9 dilution of the culture is needed to plate 1000 cells.
a. To calculate the predicted number of colonies when you plate 0.1 ml from the 10^-6 dilution onto YEPD, you can use the following formula:
N = (number of colonies)/(volume plated × dilution factor).
First, you need to calculate the total number of cells in the culture that were exposed to UV light:
N0 = 2 × 10^10 cells/ml × V, where,
V is the volume of the culture that was exposed to UV light.
Since we don't know the volume of the culture, we can't calculate N0 directly. However, we do know that the survival rate after the UV exposure was 20%, which means that only 20% of the cells were still alive:
N = 0.2 × N0
Now we can calculate the number of cells in the 10^-6 dilution that we plated:
N1 = 10^6 × N0 = 2 × 10^16 cells/ml.
Then we can calculate the number of surviving cells in the 10^-6 dilution that we plated:
N2 = 0.2 × N1 = 4 × 10^15 cells/ml
Finally, we can calculate the predicted number of colonies:
N = N2 × 0.1 ml/(10^-6) = 4 × 10^11 colonies/ml
b. To have 40 surviving colonies on the plate after the 20 sec UV exposure, you need to plate a number of cells that will give rise to 40/0.2 = 200 cells after the UV exposure. Let's call this number N3. We can calculate N3 as follows:
N3 = 200 cells/0.2 = 1000 cells
c. To calculate the dilution of the culture that we need to plate to get 1000 cells in 0.1 ml, we can use the following formula:
N4 = N3 × (volume plated × dilution factor) = 1000 cells
N5 = N0 × dilution factor
N6 = N5 × (volume plated × dilution factor)
= N4N5/N6 = dilution factor 2 × 10^10 cells/ml × dilution factor × 0.1 ml
= 1000 cells
dilution factor = 5 × 10^-9
