Answer:
They are working in the best interests of corporations
Explanation:
Corporations and industries are responsible for a large percentage of environmental pollution being witnessed in several regions of the world. The pollutions have negative consequences for the environment and the organisms living in it, including humans. Hence, formulating laws to regulate the amount of pollution that can be added to the environment is in the best interests of the public. Any person that fights against these laws is likely working in the interests of industries and corporations and not the public in its entirety.

how does the sodium atom bond to the chlorine atom ?
Explanation:
It is happening when a sodium atom loses an electron to a chlorine atom and because of that sodium atom is becoming a positive sodium ion and the sodium ions and chloride ions form an ionic lattice.
Sodium - Na
Chloride - Ch
Sodium and Chloride are both elements that cannot be found separately and free in nature but they are found as bonded together.

Explanation:
what is blood circulation?
Answer:
blood circulation is where blood circulate.
Explanation:
In this procees the heart purifies the blood, then oxygen is dissloved in blood
it takes oxygen to all over our body.
1. "For oxygen to enter the blood, how must the concentration of O2 in the alveoli compare to O2 in the blood?" 2. "For carbon dioxide to leave the blood and enter the alveoli, how must the concentration of CO2 in the blood compare to CO2 in the alveoli?" 3. "When diffusion has reached equil- ibrium, we say that the net movement of the molecules is zero. Does movement stop? Explain."
Answer:
1. Concentration of O2 in the alveoli must be more than that of the blood
2. Concentration of CO2 in the blood must be more than that of the alveoli
3. Movement does not stop (find the explanation below).
Explanation:
Gaseous exchange i.e. taking in of O2 and taking out of CO2, takes place in the alveoli/air sac of the lungs. However, the movement in and out of O2 and CO2 from the alveoli into the bloodstream and vice versa follows the principles of SIMPLE DIFFUSION. Diffusion is the process whereby substances move from a region of high concentration to a region of low concentration until they are evenly distributed. Based on this, the following will occur:
1. The concentration of O2 in the alveoli must be more than that in the blood in order for oxygen to enter the blood via diffusion.
2. The concentration of CO2 in the blood must be more than that in the alveoli in order for carbon dioxide to leave the blood and enter the alveoli via diffusion.
3. When the rate of diffusion is at equilibrium i.e. no net movement is occuring die to equal concentration of the substance on both sides, the substances begin to move in the opposite direction at an equal rate. Note that, at equilibrium, MOVEMENT DOES NOT STOP, however, there is an equal rate of movement.
beautiful clownfish named Bozo, a common salt water fish. Zara already has a tank with goldfish at home. Use your knowledge of diffusion & osmosis to tell Zara how to take care of Bozo.
Answer:
See the answer below
Explanation:
Zara should keep the clownfish and the goldfish in separate tanks - the goldfish in a freshwater tank and the clownfish in a salt water tank.
If the goldfish is kept in a salt water tank instead of freshwater, it may die due to dehydration because the salt water would be hypertonic to the cells of the fish. Water would move osmotically from the cells of the fish into the surrounding water and the fish may eventually die due to dehydration.
If the clownfish is kept in freshwater instead of salt water, it may die due to excessive water. The freshwater would be hypotonic to the cells of the fish and water would move osmotically from the surrounding water into the cells of the fish. Eventually, the cells would become turgid and may start lysing, leading to the death of the fish.

The researchers predicted that for any particular concentration of substrate, the C. Aurantiacus enolase catalyzedreaction is more rapid at 55 C. Than at 37 C. Provide reasoning to justify the researchers prediction.
Answer:
It's justified because an increase in temperature will lead to increase in the enzyme catalyzed reaction
Explanation:
Now, as the temperature is increasing, the kinetic energy of molecules will also be increasing and this implies that the collision between the substrate and enzyme will increase i.e substrate that's attached to its appropriate active site of enzyme that results in an increase in reaction.
However, if the temperature is too high, it can cause the enzymatic activity to denature.
In summary, when talking about catalyzed reactions, an increase in temperature will cause the bond between molecules to loosen and this results in catalyzation.

3. autism (neurexin 1), acute intermittent porphyria, albinism, ataxia-telangiectasia, Beckwith–Wiedemann syndrome, Best's disease, beta-ketothiolase deficiency, beta thalassemia.
4.Autism is related to some changes in chromosome 11, although it is characterized as a psychological disorder. It is usually identified in childhood, between 1 and a half years and 3 years, although the initial signs sometimes appear in the first months of life. The disorder affects the child's communication and ability to learn and adapt. Chromosome 11 Duplication Syndrome is a chromosomal alteration that interferes with child development, which may trigger motor, cognitive, language and socialization delays, inability to perform simple motor activities, weight and height deficit, facial dimorphisms and congenital malformations. Jacobsen's syndrome is an inherited disorder caused by the deletion of a specific region of the long arm of chromosome 11, which covers the 11q24.1 band. Patients with this disorder have a phenotype characterized by delayed neuropsychomotor development, craniofacial anomalies, diverse heart defects and blood dyscrasias. Signs and symptoms include: Heart defects; mental delay; difficulty feeding in childhood; attention deficit; hyperactivity; skeletal malformation, among others.

Question 1
Explain why your model demonstrates how crossing over is important to genetic variation in a species.
Question 2
Look at the offspring you created in your model. Have any of the offspring inherited a more beneficial genetic combination than the others? How could this affect their survival? Explain your reasoning.
Question 3
Why is it impossible to predict the phenotype of the offspring by observing only the phenotype of the two parents?
Answer:
the last one is:
In the process of meiosis, alleles separate and are added to the gametes in an independent manner. While each gamete (egg or sperm cell) therefore contains one allele for each gene, it's impossible to know which allele, because alleles segregate in a random manner. However, it's possible to calculate probabilities that the offspring will have a given allele using Punnett squares.
Explanation:
Crossing over process results in new combinations of alleles in the gametes (egg or sperm) formed, which ensures genomic variation in any offspring produced.
What do you mean by crossing over process?Chromosomal crossover, or crossing over, is the exchange of genetic material during sexual reproduction between two homologous chromosomes' non-sister chromatids that results in recombinant chromosomes.
This process, also known as crossing over, creates gametes that contain new combinations of genes, which helps maximize the genetic diversity of any offspring that result from the eventual union of two gametes during sexual reproduction.
Crossing over is an enzyme-mediated process, where the exchange of genetic material between non-sister chromatids of homologous chromosomes takes place.

Meditation is a practice of sitting still and quiet for minutes or even hours. It has been practiced for thousands of years and is even a part of religious practices for some people. Carefully controlled, repeated measurements of brain activity have shown that meditation does increase certain chemicals in the brain and even grows the part of the brain that helps people connect with their current surroundings and activities.
Are claims about the effects of meditation most likely scientific or pseudoscientific?
(Answer:) this is most likely to be scientific, (Explanation:) because, if you look at the question it says 'are the effects of medditadion scientific?... ect', and if you look back on your description of meditation, in the third sentence, they certainly state information based on scientific study!

predict what would happen
to the biotic and abiotic factors in Fontanelle Forest and the surrounding
area ecosystem with the increase of deer.
Answer:
With increase of deer, there will be a decrease of producers.
Explanation:
Increasing of deer populations means decreasing of producers. As more and more deers are eating plants, the producer population will decrease. Thus, the producer population are in demand and deers will eventually need to fight for food with other deers–– this is known as competition, which is a biotic factor. An abiotic factor can be lack of oxygen once the producer population has been decreased due to the increase deer population.
Some cells are specialized for
facilitated diffusion, a form of passive
transport. What sorts of structures
would these cells have more of?
Answer:
The cells specialized in passive diffusion have a greater amount of membrane structures called transport proteins.
Explanation:
Facilitated diffusion is a transmembrane transport mechanism, which consists of the passage of substances through the cell membrane by means of a transporter.This process does not require energy, as it is a passive transport, and depends on an ionic gradient or concentration.
The carriers of facilitated diffusion can be integral membrane proteins, so a cell specialized in this type of transport must have abundant transport proteins.

Answer:
Excess sediment in water may cause a reduce in light penetration decreasing algae's(an important food source) ability to photosynthesize therefore not allowing it to grow. It will stop fish from seeing well enough to move around or feed. Sediment can clog fish gills, reducing resistance to disease and lowering growth rates.Certain chemical pollutants bind to sediment and so if there is excess sediment it can very rapidly change the water quality. These
chemicals that bind to the sediment are dangerous to small animals and plants as well as larger forms of life.
