Answer:

For A your pupils will shrink for B your pupils will dilate.

Answer:

When you look at something that is bright, your pupil may shrink.

When you look at something dim, your pupil may get larger.

Explanation:

I think your pupil may get larger if you look at dim light because your eye may have a hard time seeing what's going on. And the opposite may happen when you look at bright light.

Answer:

neurons

Explanation:

I was reading an article and that was the only thing that really stood out...

Answer:

See explanation

Explanation:

According to the theory of evolution,species which are better adapted to their environment tend to survive and reproduce in a population passing on these favourable characteristics to their offsprings.

During sexual reproduction, genes can be arranged in new ways from chromosomal crossing over and recombination. This introduces new gene combinations(genotype) and ultimately variation in the population.

This variation may also lead to the observation of new phenotypes in the population.

Laying the groundwork for the 'germ theory of disease, Louis Pasteur discovered that organisms cannot spontaneously arise, but must be introduced into an environment.

Louis Pasteur was a chemist and microbiologist. He is known for the discovery of vaccines, fermentation, and pasteurization.

The germ theory is given by Pasteur. He first of all states that process fermentation is done by living organisms, bacteria, and yeast.

Thus, option B. Louis Pasteur is correct.

Answer:

is a thick band of neural fibers enabling communication between the two brain hemispheres.

Explanation:

A brain can be defined as an organ of soft nerve tissue that is found in the skull of vertebrates and it's typically responsible for the coordination of nervous activities, intellect and sensation.

The human brain consists of various sections and these includes;

I. Anterior Cingulate Cortex (ACC) which resembles a bow or collar surrounding the frontal part of the corpus callosum. This is the frontal part of the cingulate cortex which helps to make complex cognitive functions such as impulse control, decision-making, emotions and empathy.

II. Ventral prefrontal cortex in humans are interconnected with the brain and are responsible for the processing of risk, empathy, fear and social decision-making

III. The Cerebral Cortex: this part of the brain primarily comprises of grey matter, foldable sheets of neurons and forms its outermost layer. Therefore, cerebral cortex is known as the outermost layer of the brain (cerebrum) and thus, makes up half of its weight. It is about 2.5 millimeters in thickness and as such it's able to fold.

The corpus callosum is a large, thick band of C-shaped neural fibers found beneath the cerebral cortex and it's saddled with the responsibility of enabling communication between the two brain hemispheres i.e the right hemisphere and the left hemisphere.

Answer: hello your question has some missing data attached below is the missing data

Applying the Michaelis-Menten Equation

An enzyme is found that catalyzes the reaction X ⇋ Y Researchers find that kcat for this enzyme is 600s^-1 and carry out several additional experiments.

answer :

substrate concentration [ x ] = 10⁻⁵ M

Explanation:

Given data:

[Et ] = 10 * 10⁻⁹ M ,  

Reaction velocity ( V₀ ) = 3* 10⁻⁶ Ms⁻¹

applying Michaelis-Menten  Equation

= 3* 10⁻⁶ = [tex]\frac{600 *10*10^{-9} * (X) }{10^{-5} + (X) }[/tex]  ,    

= ( 3 * 10⁻⁶ )( x ) + ( 3 * 10⁻¹¹ ) = ( 6 * 10⁻⁶ ) ( x )

hence the substrate concentration [ x ] = 10⁻⁵ M

(3) Hypothesis is the assumption which are taken on the behalf of the observation on small scale . They can be correct or incorrect depends on the number of observation and Hypothesis.

(4) Viruses are included in any of the kingdom because they are on the intermediate line of living and non living as they show properties of non living outside the host and properties of living inside the host

Answer:

Post reproductive isolation → Hybrid sterility

Explanation:

The biological concept of species states that individuals of a species can not mate and reproduce with individuals of another species. But if they get to reproduce, the progeny will not be viable or fertile. There will not be any reproductive success.

There are different reproductive isolation mechanisms, which are barriers that inhibit or interrupt the genetic flow between different species.

Reproductive barriers are isolation mechanisms that prevent mating between two or more species. The prezygotic mechanism avoids fertilization between individuals of different species, while the postzygotic mechanism impedes the zygote to develop and reach the adult stage.

Postzygotic mechanisms or barriers include

In the exposed example, it seems that the mountains separating the frogs´ populations made a place for the development of postzygotic barriers, specifically hybrid sterility. Frogs from one population get to mate and produce offspring with the frogs of the other population, but their progeny is sterile.

Answer:

Locations along rivers meant faster travel upstream and downstream to rule territories. The city became the place where the ruler or rulers lived together in a stationary spot. The city's location along early rivers encouraged stronger government, which in turn encouraged stronger cities.

Rivers are one of the most crucial resources that played a major role in the development in ancient times. It led to river valley civilization that influenced the location and kingdoms.

The river valley civilization was one of the most important events that led to the establishment of many kingdoms and regions. The proximity to the river banks influenced many factors.

The cities located on the riverbanks have greater development in services including import, export, travel, agriculture, accessibility, etc. This allowed the people to practice agriculture on a large scale due to the availability of the irrigation system.

The river banks allowed the cities to grow as major trade centers and allowed downstream and upstream travel easier. This also led to the emergence of strong government systems.

Therefore, the proximity to major rivers led to river valley civilization.

Answer:

Due to inclusion of more steps of photosynthesis.

Explanation:

My model is more advance than the student's original model which provides more information about the process of photosynthesis to the learners by explaining various parts of photosynthesis. My model presents the various steps of photosynthesis in a very efficient way with the help of including some extra parts. The student's original model is not more advance so it can't provides more information about the process of photosynthesis so that's why my model provides more information about photosynthesis.

Answer:

This model shows all the major molecules involved in the Calvin cycle and how they change at each stage of the process. This added detail would clarify that the Calvin cycle is a series of complex steps. The student’s original model didn’t show this breakdown at all, and it shows only the final products. This model also shows the number of each molecule created, which the original model doesn’t do.

Answer:

Integrin molecules serve as stable, permanent anchors that anchor a cell to the extracellular matrix.

Explanation:

Integrins are transmembrane protein receptors that attach the cell cytoskeleton to the extracellular matrix (ECM) in animal cells. These glycoproteins (integrins) are highly dynamic heterodimeric molecules that anchor cells in their position and transduce signals into and out of cells. Integrin-ligand binding activates signaling pathways that are involved in fundamental cellular functions including, among others, organization of the cell cytoskeleton, cell migration, regulation of the cell cycle, etc.

The statement i.e. not true is Integrin molecules serve as stable, permanent anchors that anchor a cell to the extracellular matrix.
