Many organisms in the ocean (like plankton) rely on this source of food. What effects do you think this change in the decrease speed of the ocean currents could have on living things on the ocean?
Please help
Answer:
If the speed of ocean currents slows down, some living beings in the ocean would find it difficult to feed and reproduce.
Explanation:
As we already know, ocean currents act as a transport chain that transports hot water to the poles and cold water to the tropics. However, this ability to transport ocean currents also acts in the transport of nutrients and food for living beings that live on the seabed and do not move, but live in a fixed place. They also transport the reproductive cells of these beings to other places in the ocean, being important in the reproduction of marine life. If the speed of ocean currents decreases, the feeding and reproduction of some marine life organisms will be impaired.
Which of the following is true about environmental hazards to humans?
A)
Children are more at risk than adults because they take in more air per unit mass than adults.
B)
Adults are most at risk because they have the highest exposure to environmental hazards.
C)
Elderly people are most at risk because their immune systems do not perform efficiently.
D)
Children are least at risk because they have well functioning immune systems.
E)
Adults are most at risk because they take in more pollutants relative to their size than children.
Answer: A)
Explanation:
Children are at a higher risk of suffering negative effects from environmental hazards than adults, because children do not have fully developed immune systems. In addition, children have a higher exposure to environmental hazards, because they spend more time outside, on average, than adults. Children also take in more air per unit mass than adults, which means that they also take in more pollutants relative to their size.
Why are mutations a significant component of evolution and natural selection?
Answer
A
Mutations occur when a population needs a new trait to survive.
B
Mutations are the only source for new alleles in a population’s gene pool.
C
Mutations occur when a species population has become too large.
D
Mutations are a major source of extinction for various species
Answer:
B
Explanation:
process of elimination. The other ones were wrong tbh. Also, in natural selection genetic variation/mutations are a HUGE FACTOR according to darwins 3 principles of evolution.

Which of the following is involved in the opening of stomata for the gas exchange of the plant?
Answer: Osmotic Pressure, lb/in2
Explanation:
Osmotic pressure is involved in the opening of stomata for the gas exchange of the plant.
What are stomata?In the epidermis of tree leaves and needles, there are cell structures called stomata that play a role in the exchange of water and carbon dioxide between plants and the atmosphere.
Transpiration and gas exchange is made possible by stomata. It is surrounded by two guard cells that regulate how the stomata open and close. Stomata open during the day for gaseous exchange and to release water vapour during transpiration. The stomata open and close in response to changes in the turgor pressure within the guard cell.
Hence, osmotic pressure is responsible for the opening and closing of stomata.

All Hawaiian honeycreeper bird species have similar skeletal and muscle structures. However, each Hawaiian honeycreeper species has a bill specialized for eating certain foods. What would a scientist most likely conclude based on this observation? Artificial selection shaped the bill for eating certain foods. Increased genetic variation resulted in similar skeletal and muscle structure. Changes in each honeycreeper species occurred independently, but resulted in similar traits. Honeycreepers arose from a single species that migrated to Hawaii and adapted to different niches over time.
Answer:
The correct answer is - Honeycreepers arose from a single species that migrated to Hawaii and adapted to different niches over time.
Explanation:
All Hawaiian honeycreeper bird species share similar muscle and skeletal structures. This suggests that all Hawaiian bird species arose from a common ancestor and evolved due to different environmental conditions such as eating particular foods for particular species.
It is believed to be a single species of honeycreeper who migrated from the mainland to Hawaiin island and adapted to different niches over time by the process known as natural selection.

In a human, the movement of glucose from the digestive tract to muscle cells is most directly a result of
Answer:
absorption and circulation
Explanation:
While digestive enzymes are produced in numerous parts of the digestive system, the pancreas produces the majority of them.
What is the important role of metabolism in digestive tract?In the digestive tract, digestion and absorption take place. All body cells may access the nutrients after they are absorbed, and the cells use them for metabolism.
The six actions, or functions, of the digestive system prepare nutrients for use by body cells.
The gastrointestinal tract, which was previously mentioned in this study, is a specialized sensory system.
In charge of detecting ingested glucose and relaying information to peripheral tissues or the brain to control glucose metabolism.
Therefore, In a human, the movement of glucose from the digestive tract to muscle cells is most directly a result of absorption and circulation.

8. Genetic engineering has directly increased productivity in which
U.S. industry?
Answer:
Agriculture
Explanation:
Genetic engineering can be defined as the use of genetic techniques aimed at modifying the genome of living organisms, thereby being used to develop Genetically Modified Organisms (GMOs). In the USA, genetic engineering methodologies have been used in agriculture to improve crop yields and reduce costs (for example, by reducing the need to use pesticides). Some of the most important genetic engineering techniques that nowadays are being used in agriculture research include biolistic transformation, Agrobacterium-mediated transformation, the CRISPR-Cas9 genome editing system, etc.

survive within the changing environmental limits.
Answer:
living, components can likewise influence an organic entity's capacity to make due in an environment. They incorporate food accessibility, rivalry with different life forms, plant cover accessibility, predation, sickness, parasitism, swarming, territory discontinuity and the presence of human populaces. An absence of trees can influence populaces of birds or other arboreal organic entities, which may depend on tree cover for settling and stowing away from hunters. Some biotic elements influence abiotic factors also, for example, plants that become taller than contending plants and square daylight, or an absence of disintegrating natural matter or nitrogen-fixing microorganisms that prompts low nitrogen levels in the dirt.

10. Wei saw a special type of plastic that would melt and become a liquid when it was placed in the sun, but it would not melt when placed under a desk lamp. Why does light from the sun melt the plastic when light from the desk lamp does not? Because the plastic can take in energy from the light from the sun but not from the light from the lamp. b Because light from the sun carries heat molecules, and light from the desk lamp does not. Because light from the sun pulls energy out of the plastic, and light from the desk lamp does not. Because the sun gives off a type of light that carries erlergy, and light from the desk lamp does not.

Earth is a beautiful planet that revolves around a star called Sun, which is located in one of the arms of our Milky Way Galaxy. It is the only planet known to support life in the Solar System. Humans are the most intelligent civilization on this planet. It's blue when seen from space. Recently, Earth 29 spacecraft was able to land on this planet, after 28 unsuccessful landings of Earth series of spacecrafts. We were able to learn many things about humans, most important of these was the most spoken language of them, which they call English. According to experts, humans are not yet ready to know about our existence. It can take about 1 or 2 more centuries, until they are ready to know about us.

DNA transcription
DNA transcription is a process carried out by messenger RNA, which has as its ultimate goal the formation of proteins.
This transcription occurs with the combination of nitrogenous bases, which combine in such a way:
C - G
G - C
A - U
T - A
So, the transcription of the ACC base would be equivalent to UGG, and the process is called transcription.
