What is Nervous System?According to biology's classical idea of the nervous system, an animal's nervous system is a highly sophisticated component that coordinates its movements and sensory data by sending and receiving signals from and to various regions of the body. In order to react to such occurrences, the nervous system and endocrine system collaborate to detect environmental changes that have an effect on the body.
Around 550–600 million years ago, worm-like invertebrates were the first to develop nervous tissue. The discovery of electrical impulses in plants and their utilization in recent decades, however, has called into question this conventional wisdom. These findings have led some researchers to suggest that plants have neural systems and that the science of plant neuroscience should be established.

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.

why is the property of water important to organisms in Aquatic and land habitats?
Answer:
Without a water supply, organisms in aquatic and land habitats will die. Organisms without access of water cannot access oxygen, and as a result of that, they would die. Oxygen is needed for organisms in order to survive. Water also helps insulate the living environment for these organisms.

C RNA is transcribed into protein, which is translated into DNA. D RNA is translated into DNA, which is transcribed into protein.
Answer:
A. DNA is transcribed into RNA, which is translated into protein
Explanation:
The process that accurately explains the process of gene expression is: DNA is transcribed into RNA, which is translated into protein. The correct option is A.
What is gene expression?Gene expression is the procedure by which genetic information is utilized in the biosynthetic pathways of a functional gene product.
This aids in allowing it to produce end products such as protein or non-coding RNA as well as, as a result, affect a phenotype.
Several factors affect gene expression, along with molecules inside the cell, mutations that cause dominant negative effects.
It also cause haploinsufficiency, signaling molecules from neighboring cells and the surrounding environment, and epistasis. Several molecules within the cell influence gene expression.
The following process accurately describes gene expression: DNA is transcribed into RNA, which is then translated into protein.
Thus, the correct option is A.

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.

Halite has a mass of 33.0 g and a displaced volume of 17 ml. What is the density of halite?
Answer:
1.94 g/mL
Explanation:
Following Archimedes' principle, the displaced volume of an object (meaning the volume of water it displaces if completely submerged in it) is equal to the object's volume.
Thus the volume of this Halite sample is 17 mL.
The density of an object is equal to the mass divided by the volume:
density = mass / volumeWe input the data we know:
Density = 33.0 g / 17 mLAnd calculate the density:
Density = 1.94 g/mLhow will CO2 and h20 leave your body after cellular respiration?

Researchers studied the relationship between glucose concentration oxygen mobile and ATP production in one type of mammalian cell. Cells were isolated and cultured and growth medium containing either 1.5MM glucose or 25 MM glucose and at oxygen levels that varied from 0% to 21%. The researchers determined the concentration of ATP per cell under the different conditions. The ATP concentrations are shown as relative to maximum ATP concentration obtained when cells were cultured in the presence of 25MM glucose and 21% oxygen standard culture conditions.
Describe the relationship between the concentration Agricole Cindy Coach medion md ATP concentration in cells.
Answer:
Direct relationship.
Explanation:
There is direct relationship between the concentration of oxygen and ATP concentration in cells because with the increase of oxygen, increase also occur in the concentration of the energy that is produced in the form of ATP. Direct relationship means if one increase the other automatically increase while on the other hand, if one decrease the other also decreases. So if oxygen is increases, ATP production is also increases and vice versa.

Answer:
One of the 10 human body systems that each organ is a part of. These bodily systems are linked and rely on each other in order to work. The brain and neurological system must interact with the heart in order for it to beat. Furthermore,the nutrients that our digestive system provides to our skeletal system help it create strong and healthy bones. The body's cells receive water, oxygen, salt, plus nutrients from the circulatory system. The epidermis, respiratory, and excretory systems all function to remove wastes from the cells. With the help of sweat glands, the skin functions as just another excretory organ to remove waste from the body. Through sweat, it removes water, salts, plus urea out from body.

which category of genetic changes does not lead to the formation of oncogenes? group of answer choices transpositions point mutations copy number changes meiotic recombination translocations
Copy number changes is considered as genetic changes which does not lead to the formation of oncogenes.
Copy number change- The cytogenetic level of resolution, known as copy number variation (CNV), involves both duplications and deletions of sequences that generally have lengths between 1,000 base pairs and 5 megabases.
Genetic Change- Genetic mutations, which occur as our cells divide and generate duplicates of themselves, are modifications to your DNA sequence.
Base Pairs- The DNA molecule is made up of two bases (or nucleotides) that contain nitrogen. Adenine (A), cytosine (C), guanine (G), and thymine (T) are the four bases of DNA (T). These bases come in certain pairings (A with T, and G with C).

what would happen to the volume of air in the swim bladder if the fish didn't change the amount of air in it?
If the fish did not change the amount of air in the swim bladder, the volume of air would decrease because the pressure inside the swim bladder would increase.
Swim bladder It is an organ present in fishes that help them to adjust their buoyancy. It is a sac filled with gas that helps the fish swim by maintaining buoyancy.Fishes can adjust, i.e., increase or decrease the amount of air present in their swim bladder to regulate the volume and the pressure in them.Thus, if the fish did not change the amount of air in the swim bladder, the volume of air would decrease because the pressure inside the swim bladder would increase.

Which statement about matter is NOT TRUE?
a. Atoms make up matter.
b.
Matter exists only when you can see it.
Living things are matter.
c.
d. Matter is made up of atoms.
Answer:
B. "Matter exists only when you can see it."
Explanation:
Since an atom is the smallest unit of matter, both "atoms make up matter" and "matter is made up of atoms" are true.
Living things like lions or plants are made up of atoms, which is the smallest unit of matter.
This means that by the process of elimination, B. is correct.
Matter exists regardless if you can see it or not. Humans cannot see air, but it is still made up of oxygen atoms (which are matter).
