If a scientist makes the argument that she has found DNA evidence that shows that evolution does not exist, the evidence would be the weak physical similarities among closely related organism and also among distantly related.
Answer:
Epinephrine, also known as Adrenaline
Explanation:
Adrenaline impacts short-term mood and can take seconds to flood your system.
*it may also be cortisol, I'm not sure if there's more context. Cortisol takes longer to work and can have long-term effects.
Answer:
The correct answer is option D) "K".
Explanation:
In this example the wolf population is described by the equation "ΔN/Δt=rN(K−N)K". Even tough the variables are not defined in the question, we can conclude that the effect of the moose population will be given by a factor that has a positive effect in the wolf's population because "as moose populations increase, wolf populations also increase". The factor "K" fits the description because it gives a positive effect on "ΔN/Δt". "K" is a factor that multiplies "rN" at two different levels, therefore the higher the value of "K", the higher value of "ΔN/Δt" will be.
Answer:
Explanation:
First-generation (F1) progeny only showed the dominant traits, but recessive traits reappeared in the self-pollinated second-generation (F2) plants in a 3:1 ratio of dominant to recessive traits. Mendel then crossed these pure-breeding lines of plants and recorded the traits of the hybrid progeny
Lymphocytes that destroy foreign cells or virus- infected cells are cytotoxic T cells.
<h3>What is cytotoxic T cell?</h3>
- A particular class of immune cell that is capable of eliminating specific types of cells, such as virus-infected cells, cancer cells, and alien cells.
- To destroy cancer cells, cytotoxic T lymphocytes can be isolated from other blood cells, cultured in a lab, and then administered to a patient.
- White blood cells and lymphocytes both fall under the category of cytotoxic T lymphocytes.
- It is also known as a killer T cell and a cytotoxic T cell.
- The helper T cell and the cytotoxic T cell are the two main subtypes of T cells.
- Helper T cells, as their names imply, "assist" other immune system cells, whereas cytotoxic T cells "kill" virally-infected cells and tumours.
- The TCR cannot directly bind antigen, unlike an antibody.
