cytotoxic t cell activation by cell-mediated immunity results in the ______ and apoptosis of infected cells.
Answers
The cytotoxic T cell activation by cell-mediated immunity results in the lysis and apoptosis of infected cells. The mechanism of cell-mediated immunity is crucial in the defense against intracellular organisms like viruses and bacteria that infect cells.
The immune response begins when an antigen-presenting cell, or APC, presents an antigen to a T helper cell. T helper cells help activate cytotoxic T cells and other immune cells. Once cytotoxic T cells recognize the antigens presented by APC, they release proteins called perforins and proteases.
Perforins make holes in the cell membrane of infected cells. Proteases enter through the holes and break down proteins inside the cell. In the end, the infected cell undergoes lysis and apoptosis. This mechanism is crucial in the defense against intracellular pathogens such as viruses, as it destroys the infected cells, preventing the spread of the infection.

Most seeds need water, food, and a little heat to become new plants. 12. A new plant has the same life cycle as its plant. Critical Thinking 13. How ore new plants that grow from seeds like their parent plonts?
Answers
Seeds grow with the help of various natural resources like water, oxygen, and sunlight, which help them to sprout and grow roots and develop into new plants. Some seeds grow as soon as they land in the ground, while others need a specific time period to grow.
The life of a plant begins with a seed that contains the necessary resources required for the plant's growth, which includes the embryo, endosperm, and protective seed coat.
The process through which plants grow, reproduce, and die is called their life cycle. It includes different stages like germination, growth, flowering, pollination, fertilization, seed production, and dispersal.
Seeds need water, food, and a little heat to grow into new plants. Water helps seeds to soften and expand, and food helps them to provide the necessary nutrients required for growth. The heat helps seeds to break dormancy and activate enzymes that speed up the germination process.
A new plant has the same life cycle as its parent plant. Plants have a unique life cycle, and every stage of the life cycle is essential for their growth and development. New plants inherit their genetic traits from their parent plants, and their life cycle is the same as that of their parent plant.
New plants that grow from seeds inherit their genetic traits from their parent plants and have the same life cycle as their parent plants. The life cycle of a plant includes the stages of germination, growth, flowering, pollination, fertilization, seed production, and dispersal. Thus, new plants that grow from seeds are like their parent plants.
___________ allows chyme to enter into the large intestine & prevents it from going back into the small intestine.
Answers
The ileocecal valve is the structure that allows chyme to enter into the large intestine and prevents it from going back into the small intestine.
This valve is situated between the cecum and the ileum, the final segment of the small intestine (the first part of the large intestine). It is made up of a ring of smooth muscle tissue that flies open and shut to control the passage of food from the small intestine into the big intestine. The valve opens when the small intestine constricts and forces chyme into the cecum, allowing the substance to pass into the large intestine. The valve closes when the pressure in the large intestine increases, preventing any material from returning to the small intestine. The ileocecal valve is crucial for ensuring correct digestion of food and for shielding the small intestine from potentially hazardous compounds created in the large intestine.

many commercial e.coli plasmids that are used by laboratory researchers to make rna have a t3 rna polymerase binding site and a t7 rna polymerase binding site in them. why do you think that the plasmid would have both a t3 and t7 binding site?
Answers
In summary, having both T3 and T7 RNA polymerase binding sites in a plasmid provides researchers with greater flexibility and convenience in conducting RNA synthesis experiments.
T3 and T7 RNA polymerases are enzymes that specifically recognize and bind to their respective binding sites to initiate RNA synthesis. T3 polymerase recognizes the T3 promoter sequence, while T7 polymerase recognizes the T7 promoter sequence. These two promoters have different sequences, so they bind to their corresponding RNA polymerase with high specificity.
Therefore, having both T3 and T7 binding sites in a plasmid means that researchers can choose which promoter to use for RNA synthesis, depending on their experimental needs. This also allows researchers to compare the efficiency and specificity of RNA synthesis by T3 and T7 polymerases using the same plasmid backbone.

Imagine that 90% of Cuba’s area became unsuitable for wildlife due to human activities. How many reptile
and amphibian species would you expect to find in Cuba then? Support your answer with evidence from
Figure 1.
Answers
We could expect to find less than 50% of reptile and amphibian species in Cuba if 90% of it's area becomes unsuitable for wildlife due to human activities.
The total area of the island is mentioned as 100,000 km² in Figure 1. Therefore, to determine the reptile as well as amphibian species in Cuba, we first need to calculate the area (in km²) that has become unsuitable for wildlife as:
100,000 x 90% = 90,000 km²
Now, we can subtract this value from the total area of the island as:
100,000 - 90,000 = 10,000 km²
Hence, only an area of 10,000 km² is suitable for wildlife since 90%, i.e., 90,000 km² of the area has become unsuitable for wildlife due to human activities.
Therefore, we could expect to find less than 50% of reptile and amphibian species in Cuba as is evident in Figure 1.

How do the products of glycolysis and the Krebs cycle relate to the electron transport chain?
Multiple Choice
1.Glycolysis and the Krebs cycle produce the molecules that shuttle electrons to the electron transport chain.
2.Glycolysis and the Krebs cycle are the final receptors for electrons that flow through the electron transport chain.
3.Glycolysis and the Krebs cycle produce CO2, which binds to electrons in the electron transport chain.
4.Glycolysis and the Krebs cycle produce the ATP necessary to start the electron transport chain.
5.Glycolysis and the Krebs cycle use CO2, which is produced in the electron transport chain.
Answers
Because they utilise electrons from the electron transport chain to produce their products, glycolysis and the Krebs cycle are related to the electron transport chain.
Electron carriers like NADH and FADH2 are reduced and get electrons via chemical processes beginning with glucose during glycolysis and the Krebs cycle.
These electron carriers deliver their electrons to the electron transport chain, where they can be applied to build an ion gradient that will lead to the production of ATP.
The molecules that transport electrons to the electron transport chain are created by glycolysis and the Krebs cycle. CO2, which is created in the electron transport chain, is used in glycolysis and the Krebs cycle.
The electron transport chain that powers this action is fueled by the NADH and FADH produced during the Krebs cycle, ultimately resulting in 38 molecules of ATP.
