Answer:
D
Explanation:
Brain can create new connection between neurons.
The ability of the brain to adapt and compensate for damage by forming new connections among remaining neurons is called Neuroplasticity. Despite having part of her brain removed as an infant, Maya exhibited this through her high school graduation, scholarship award, and absence of deficits from the surgery.
The ability of Maya's brain to adapt and rewire itself after a part of it was removed is known as Neuroplasticity. The term neuroplasticity refers to the brain's incredible capacity to reorganize itself, developing new connections among remaining neurons when part of it gets damaged or removed, thus minimizing the deficits of such loss.
In Maya's case, she demonstrated impressive neuroplasticity because, despite having part of her brain removed as an infant due to a life-threatening medical problem, she graduated from high school as the valedictorian of her class, was awarded a college scholarship, and showed no deficits as a result of the brain surgery. Hence, it's worthwhile to emphasize the power of neuroplasticity in our amazing brain.

c. organ
b. tissue
d. organism
A group of organs working together to perform a certain function is referred to as an organ system, option (a) is correct.
An organ system consists of multiple organs that collaborate and coordinate their activities to carry out specific functions necessary for the overall functioning and survival of the organism. Each organ within the system has its own unique structure and function, but they work together synergistically to achieve a common goal.
Examples of organ systems in the human body include the respiratory system, circulatory system, digestive system, nervous system, and many others. These systems are interconnected and interdependent, ensuring the proper functioning and homeostasis of the organism as a whole, option (a) is correct.

Answer:
it is organ system
Explanation: all it is just process of elimination because a tissue is a group of cells working together not organs and an organism is like an animal or human not an organ and organ is not it because it is a group of them wwhy would they call it an organ if it is in a group of the thing so there u go hope this helps pls read this :)
B) Saturated fats have more carbon atoms than unsaturated fats.
Eliminate
C) Saturated fats have only single bonds on all the carbon atoms.
D) Saturated fats have only double and triple bonds on the carbon atoms.
the maximum elongation rate during transcription with and without the modified RNA polymerase enzyme
(Figure 1).
The compound amanitin, which is commonly found in toxic mushrooms, is a specific RNA polymerase inhibitor.
Amanitin binds to the RNA polymerase active site and inhibits transcription. In a second experiment, the
scientists treated the wild-type and experimental strains of S. cerevisiae with a 40 ug/mL solution of amanitin
and recorded the maximum elongation rate of the mRNA (Figure 2).
Q. Identify the dependent variable in the experiments. Identify the control group missing from the second experiment. Justify the need for this control group in the second experiment.
Dependent variable: maximum elongation rate. Control groups: wild and experimental strains not treated with amanitin. They are important to see if the change in elongation rates depends on the amanitin inhibition or any other variable.
Before answering the question, let us first review a few concepts.
→ with the modified RNA polymerase enzyme
→ without the modified RNA polymerase enzyme
(1)The dependent variable is themaximum elongation rate
Amanitin is a specific RNA polymerase inhibitor that binds to the RNA polymerase active site and inhibits transcription.
(1) Thedependent variableis themaximum elongation rate
(2) The missing control groups arewild-type and experimental strains not treated with amanitin.
(3) The importance of including the control groups is to analyze if the change in the elongation rates depends on the amanitin inhibition or any other variable.

Answer:
Explanation:
Hello!
The scientist created an experimental strain that produces a modified RNA polymerase with a single amino acid substitution. This mutation is supposed to change the elongation rate of the mRNA during transcription.
The dependent or response variable, is the one the researchers are interested in, meaning, are the characteristics that the researcher will pay attention to and measure during the experiment.
In this example, the researcher is interested in testing the max elongation rate during transcription, which is the dependent variable of this experiment.
In the second part of the experiment, both strains of yeast, wilds, and experimental, where exposed to 40ug/mL solution of amanitin and recorded the maximum elongation rate of the RNA. This is naturally to test the effects of amanitin over the elongation rate of the mRNA in both strains.
The control group is a set of experimental units that are exposed to the same conditions as the experimental groups, with the exception that they receive no treatment (or they receive a "no effective" treatment often called a placebo). The purpose of a control group is to know the natural response of the experimental units to a treatment-free environment, this way when comparing both groups, the researcher will be able to observe the differences or changes due to the applied treatments.
In the second experiment, there are missing two control groups, one made of the wild strain and the other made of the experimental strain, exposed to the same conditions as the treated strains.

The plant is an angiosperm, and the gametophyte is its dominant phase.
The plant is a moss, and the sporophyte is its dominant phase.
The plant is a fern, and sporophyte is its dominant phase.
Answer:
The correct answer would be "The plant is a fern, and sporophyte is its dominant phase".
Ferns refer to the lower plants which do not bear flowers, have leafy or feathery fronds, and they reproduce by spores.
They show alternation of generation in which sporophyte is the dominant stage.
The mature diploid sporophyte releases haploid spores with the help of meiotic divisions.
The haploid spore divides by mitotic division and matures into a haploid gametophyte. The single gametophyte bears antheridium and archegonium which release flagellated male gametes and egg (female gamete) respectively with the help of mitotic division.
The gametes fertilize to produce a diploid zygote.
The zygote divides mitotically and matures into the diploid sporophyte.
Answer:
The plant is a fern, and sporophyte is its dominant phase.
