The brain coordinates the __________ to a stimulus. What word completes this sentence?
Different kinds of receptors in the skin and organs are capable of recognizing both internal and exterior inputs. Neurons in the sensory system send this data to the brain.
What are the Sensory system?Assembling sensory neurons create sensory nerves, which pass through the spinal cord to the brain.
The brain and spinal cord make up a person's central nervous system (CNS). When a receptor is activated, a signal travels through the neurons, or nerve cells, to the brain.
The effector receives nerve impulses from the brain, which the brain then uses to coordinate the reaction.
A sensory system is made up of neural networks, sensory neurons (including sensory receptor cells), and brain regions involved in sensory perception.
Therefore, brain coordinates the sensory responses to a stimulus.

Josh and his family always rent a beach
house for summer vacation. One
afternoon, Josh and his Dad took the
boat out and when they returned pulled
up their boat on the beach and went in
to have lunch. When they returned, the
beach was covered in water and the
boat was floating offshore. What is a
likely explanation?
Answer:
The tide had probably rolled in and covered the beach with water and had swept the boat away offshore.
(I'm so sorry if this is wrong)
Hope this helps!
Answer:
High Tide
Explanation:
It seems from the question that after they returned, the beach was covered with water, High tide explains it because the tide is at it’s highest point at that time. Since the water is at it’s highest point, the boat was washed away and the beach was covered with water.

natural selection favored alleles for light skin in a. south america. b. africa. c. europe. d. australia.
Option C: Natural selection favored alleles for light skin in Europe.
The theory of Natural Selection was firstly expounded by Charles Darwin. It is a key mechanism of evaluation, the change in the heritable traits, and characteristic of a population over a generation.
Natural selection favored alleles for light color skin in Europe because of the well-known correlation between skin pigmentation and distance from the equator. Relethford strongly suggests that natural selection in response to environmental factors plays an important role in the geospatial patterning of human skin pigmentation variation. The lighter level of UVR required to synthesize vitamin D, which is higher in individuals with dark color skin means the region near the equator. The European region does not receive much UVR that's why in Europe alleles of light skin are favored.

What is an algae?Algae is an informal term for a large and diverse group of photosynthetic eukaryotic organisms. It is a polyphyletic grouping that includes species from multiple distinct clades.
Moreover, algae are photosynthetic creatures. They are neither plant, animal or fungi. Many algae are single celled, however some species are multicellular. Many, but not all of red and brown algae are multicellular.
Therefore, algae are defined as a group of predominantly aquatic, photosynthetic, and nucleus-bearing organisms that lack the true roots, stems, leaves, and specialized multicellular reproductive structures of plants.

What is recombination ?
Recombination can be defined as the process where DNA fragments are under go breakage and recombined to generate new allele combinations.
This mechanism will generate genetic diversity at the gene level in which variations in the DNA sequences of various organisms will be reflected.
In the field of heredity, recombination is the process which produce gametes with new allele combinations that were absent in the gametes of previous generations.
one of the type of recombination called Intrachromosomal recombination takes place between independently assorted alleles with loci on distinct chromosomes.
Crossover occur among loci within identical chromosomes in case of intrachromosomal recombination which is essential to keep in mind that recombination takes place during meiosis in both of these situations.

c. if you begin with one tube of e. coli, how many different types of bacteria do you expect to see in the 4th quadrant?
If we begin with one tube of E. coli, we will only see one type of bacteria in the 4th quadrant, if any type of contamination does not occur.
To observe the colonies of a bacteria in form of quadrants, we need to follow the below-mentioned steps:
To culture bacteria, we need to transfer it to a petri dish.A petri dish is coated with a layer of agar, a jelly-like substance obtained from red algae that helps in culturing bacteria.Then the required bacteria, which is E. coli in our case is collected using a sterile rod and put on the petri dish.After that, the petri dish is heated to increase the growth of bacteria and also to ensure equitable distribution of bacteria in all four quadrants.After following the above-mentioned steps we have to cover the petri dish to avoid contamination and leave it undisturbed for a few days.When we observe the dish after a few days, we will see the bacterial colonies growing in it, as shown in the adjoining image.Thus, if we begin with one tube of E. coli, we will only see one type of bacteria in the 4th quadrant, if any type of contamination does not occur.

What would happen if you did an experiment in which the iodine solution was placed in a baggie, and the starch solution was in the beaker?
If the iodine solution was placed in a baggie and the starch solution was in the beaker, and the baggie was then submerged in the beaker, a specific chemical reaction called the iodine-starch reaction would occur.
The iodine-starch reaction is a well-known test used to detect the presence of starch in a solution. Normally, when iodine solution (iodine dissolved in water) comes into contact with starch, it forms a dark blue or black color complex.
This reaction is due to the formation of an inclusion complex between the iodine molecules and the helical structure of starch.
