- Energy (ATP) is needed for active transport to occur
Explanation:
According to this question, sensor's on a spider's legs relay information via nerve electrical signals to the brain when the vibrations of a trapped insect is felt. However, for nerve cells to maintain this electric potential, ACTIVE TRANSPORT must be carried out by removing sodium from the cell and potassium must be moved into the cell.
This is a form of ACTIVE TRANSPORT because pottasium ions are moved into the cell against concentration gradient i.e. from a region where it is in low concentration to where it is in high concentration. This active transport process is usually accompanied by the use of energy in form of ATP.

In which layer of the atmosphere does the aurora borealis form? O A. The troposphere OB. The mesosphere O C. The thermosphere O D. The stratosphere SUBM
Answer:
The Thermosphere
Explanation:
Just took the test on A P E X, it's right. Hope this helps :)
Aurora Borealis forms in the thermosphere layer of the atmosphere. Therefore, option "C" is correct.
What are the different layers of the atmosphere?The atmosphere is made up of different layers which protect the life on Earth and make it habitable. There are four layers of the atmosphere troposphere, stratosphere, mesosphere, and thermosphere.
In the troposphere, the temperature rises from bottom to top. The ozone layer is present in the stratosphere. This is also known as the flying zone as no clouds are present in this layer. In the mesosphere, the air is much colder as there are gas molecules present that absorb solar radiation whereas the density of molecules in the thermosphere is very low.
The atmospheric layers protect the life on Earth.

Which among the following mineral groups, if any, contain silicon: halides
carbonates or sulfides? Explain.
Answer:
The correct answer is: none of these mineral groups contain silicon.
Explanation:
The only minerals that contain silicon are the Silicates, for example, SiO2 (silica).
Halides are minerals that consist of a combination of elements from the seventh group that can form salts (like fluorine or chlorine), with other elements such as calcium and sodium. For example: NaCl (sodium chloride).
Carbonates are compounds that contain carbon and oxygen, for example, CaMg(CO3)2 (dolomite).
Sulfides consist of sulfur with another element. For example: ZnS (zinc sulfide).

Except for a pairing of sex chromosomes, homologous
chromosomes_______.
a. carry the same genes
b. are the same shape
c. are the same length
d. all of the above
Answer:
Homologous chromosomes carry the same genes and have the same shape and length, so all the choices are correct.
Explanation:
The homologous chromosomes are so called because each of them has the same DNA molecule, giving rise to the same genes, distributed in the same location within the chromosome.
Somatic cells are diploid, which means that the genetic information that determines specific characteristics is distributed in pairs. Each of the chromosomes that form a pair comes from the father and mother, and the members of a pair are known as homologous chromosomes.
The homologous chromosomes are characterized by having the same shape and size, and contain the same genes, although the information contained in them —the alleles— may be different. Hence the possibility that one allele is dominant and another recessive on two chromosomes of a pair.
How do convection currents cause the motion of tectonic plates??
Answer:
These tectonic plates rest upon the convecting mantle, which causes them to move. The movements of these plates can account for noticeable geologic events such as earthquakes, volcanic eruptions, and more subtle yet sublime events, like the building of mountains.

Geological Oceanography
Physical Oceanography
Chemical Oceanography
Biological Oceanography
Answer: Oceanography is the study of all aspects of the ocean. Oceanography covers a wide range of topics, from marine life and ecosystems to currents and waves, the movement of sediments, and seafloor geology Geological oceanography is the study of Earth beneath the oceans.
Physical oceanography is the study of physical conditions and physical processes within the ocean, especially the motions and physical properties of ocean waters. Physical oceanography is one of several sub-domains into which oceanography is divided. Others include biological, chemical and geological oceanography.
Chemical oceanography is a broad and complex study of the metamorphosis that the chemicals within oceans, living marine organisms, and the ocean floor undergo. The ocean contains a multitude of chemicals; some are natural, and others are man-made. These chemicals enter the sea in a number of ways.
Biological oceanography is a field of study that seeks to understand what controls the distribution and abundance of different types of marine life, and how living organisms influence and interact with processes in the oceans.

How are humans affected by population growth of other organisms in anarea?
Answer:
yes
Explanation:
other organisms include things such as plants, insects and animals which can play a large role in the population. For example, if you have a sudden rise in the population of misquitoes that can be really bad since they can spread diseases to people when they are sucking blood. Antoher example is if there is a sudden growth of animals that eats a certain crop, then farmers will stuggle to maintain their crops and the list goes on. Hope this helps :)

How would you improve food safety from a food supplier standpoint (farmer, factory, production, distribution, food scientists) be very specific with your answer and make sure to use facts to justify why you believe the way you do. The explanation must be at least three paragraphs (5-8 sentences)
Answer:
Foods are the basic building blocks of living things, yet they may pose a threat and become harmful to human health in some situations [13]. Many people throughout the world become ill because of the food they eat. These diseases associated with food consumption are referred to as foodborne diseases, and they may result from dangerous microorganisms [14]. Foods can become harmful to human health or even fatal when combined with bacteria, mold, viruses, parasites and chemical toxins [13]. Therefore, it is absolutely necessary that consumers be provided with a safe food supply. The factors involved in the potential threat caused by foods are inappropriate agricultural practices, poor hygiene at any stage of the food chain, lack of preventive controls during processing and preparation of the food, incorrect use of the chemical materials, contaminated raw materials, food and water and inappropriate storage [15].

The movement of glucose across the membrane through facilitated diffusion is a form of passive transport because
Answer:
Explanation:
Glucose is a 6 carbon sugar molecule that provides energy needed by cells. Since glucose is a large molecule, it is difficult to be transported across the membrane through simple diffusion. Therefore, it diffuses across membranes through facilitated diffusion down the concentration gradient.

You remove pus from a wound and try to identify the pathogen multiple ways. The multi-locus gene tree showed your organism was most closely related to Streptococcus pyogenes but the 16S tree said it was most closely related to Streptococcus pneumoniae. Describe why this might be the case and other ways you should try to identify this organism.
Answer:
It occurs because phylogenetic analyses based on the 16S rRNA gene sequences may have insufficient resolution for distinguishing between closely related species
Another genomic method for streptococcal identification is whole-genome analysis (WGS)
Explanation:
The phylogenetic analysis of the highly conserved 16S rRNA gene sequences has recently been used to distinguish between prokaryotic species. However, this gene sometimes may show low resolution to distinguish between closely related species, and it has been suggested potential horizontal transference of rRNA genes. Moreover, multi-locus sequence analysis (MLSA) has also been used to identify species. MLSA analysis consists of analyzing simultaneously different genes and this technique has shown to have a high capacity for establishing relationships between species within a genus or genera within a family. Finally, whole-genome analysis (WGS) is the most powerful tool for distinguishing between closely species. WGS is a technique that provides a very high resolution which is based on the analysis of large-scale genome sequencing data generated by next sequencing generation (NGS) technologies.

a theory can be accepted.
B. Einstein's theory was difficult for many people to understand.
C. More evidence needed to be gathered to validate the ideas in the
theory
D. No scientific laws could be found to validate the theory.
SUBMIT
Answer:
B. Einstein's theory was difficult for many people to understand.
Explanation:
Einstein’s theory of general Relativity was largely Ignored for three decades because scientists at the time thought the theory was too complex compared to Newton's.
Therefore, it took long before the general science community accepted Einstein's theory of general relativity because Einstein's theory was difficult for many people to understand.
"B. Einstein's theory was difficult for many people to understand."
D. More evidence needed to be gathered to validate the ideas in the theory.
