Answer:
Explanation:
Cloning is a hot ethical issue in the scientific community, but bacteria clone themselves all the time. In a process called binary fission, one bacterium doubles its size and genetic material, then splits to produce two identical cells.

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.
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.

Refer to the given strand of DNA: CTG ACG GCC ACC
1. Which of the following mRNA triplets compliments ACC?
a. GAC c. UGC
b. CGG d. UGG
2. What process was involved in number 1?
a. Fertilization b. Replication
C. Transcription d. Translation
Answer:
d
Explanation:
a goes with u
c goes with g
The mRNA triplets compliments ACC is UGG and the process involved is transcription.
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.

Why do you think
organisms in the
same kingdom are
not all identical?
Answer:
Evolution, mutation, and adaptation
Explanation:
Since different organisms adapt to different environments and receive different mutations, they adapt differently and slowly change. That is why there are different species of birds, just look at the galapagos islands, there are thousands of species of finches that changed to survive on each island. The same could be said for every organism since the early organisms that we evolved from were widespread, some evolved differently than others, leading to different fish, different lizards, different early mammals, and so on. That is why humans look different than dogs or cats, we evolved best to our environment so we could survive.
Answer:
Though they are in the same kingdom which makes them makes the species they are built of different genes received from each parent.

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.

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.
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.
