D. Practice applications of scientific knoledge.
Answer:
I believe its D, technology is to make life easier with new resources, so using that definition, I think that D falls under it
Explanation:
The best definition of technology is the practice applications of the scientific knowledge. The correct option is D.
What is Technology?Technology involves the practical use of scientific knowledge to create tools, machines, and systems that improve our lives and solve problems. It is not limited to just electronic devices, but encompasses a wide range of fields including engineering, medicine, and agriculture.
Technology is the means through which we put scientific knowledge to use. It encompasses both tools (like computers) and methods (like how we make computer chips), as well as both. Although the majority of contemporary technology is electronic, this does not mean that all technology is.
While the pursuit of scientific knowledge is important, it is the application of that knowledge that defines technology.
Therefore, the correct option is D.

What information can a scientist learn directly from a single fossil? O A. What the organism looked like B. How the organism is related to organisms on Earth today C. How many offspring the organism produced D. How long the organism lived
Answer:
A. What the organism looked like.
Explanation:
From a single fossil you can see what the organism looked like, but you need more than one fossil to know how long it lived. You can't determine how many offspring an organism produced from any fossil. And how the organism is related to organisms on earth today can be learned indirectly from fossils, using other information and technology.

What do you think selectively permeable means?
A. The membrane lets nothing in or out.
B. The membrane lets certain substances move across it freely, while others must move through a “gate”.
C. The membrane lets everything in and out.
Answer:
B. The membrane lets certain substances move across it freely, while others must move through a “gate”.
Explanation:
Selective permeability is a property of cellular membranes that only allows certain molecules to enter or exit the cell. This is important for the cell to maintain its internal order irrespective of the changes to the environment. For example, water, ions, glucose and carbon dioxide may need to be imported or exported from the cell depending on its metabolic activity. Similarly, signaling molecules may need to enter the cell and proteins may need to be released into the extracellular matrix. The presence of a selectively permeable membrane allows the cell to exercise control over the quantum, timing and rate of movement of these molecules.
B. The membrane lets certain substances move across it freely, while others must move through a “gate”.
Which of the following statements is not an example of evolution that has resulted from human activity? Group of answer choices Some insect species are now resistant to pesticides. Many strains of bacteria are now resistant to some commonly used antibiotics. Like certain other crops, domesticated strawberries are larger than wild strawberries.

Smoking Doesn’t Just Hurt Your Health
(excerpt)
The arguments about smoking are usually centered around its effects on the health of smokers and nonsmokers alike. Entire ad campaigns have been developed around the idea of educating smokers about the risk that smoking poses to their health. Chances are you’ve encountered the photo of that diseased lung in your health class. Lawsuits against tobacco companies have gained a lot of media attention. Cities have gone so far as to ban smoking inside buildings, restaurants, and bars. But have you ever stopped to think about what smoking does to the environment?
It is easy to guess that smoking might pollute the air. Did you know that tobacco smoke contains more than 4,000 chemicals? Fifty of those chemicals are known to cause cancer, and two hundred are known poisons. Think about the fact that 20 percent of Americans smoke. Can you imagine how many chemicals are released into the air each year?
Cigarettes also account for an estimated 1.7 billion pounds of trash each year. Some people say the ban on smoking indoors in some cities could contribute negatively to this statistic. Because people are smoking outside, the number of cigarette butts they leave behind may increase dramatically.
A.
Smoking pollutes the air in public places, such as buildings, restaurants, and bars.
B.
Smoking not only produces negative effects on human health but also on the environment.
C.
Smoking damages the environment more severely than it damages human health.
D.
Smoking increases water pollution when cigarette butts are dumped into waterways.
E.
Smoking harms wild animals by polluting and destroying their natural habitats.
Answer: B. Smoking not only produces negative effects on human health but also on the environment.

A cell that utilizes NHEJ to repair a double-stranded DNA break which occurred in the open reading frame of a gene is susceptible to indels resulting in a frame shift mutation and ultimately a non-functional protein. False True
Answer:
True
Explanation:
The non-homologous end-joining (NHEJ) pathway is a DNA repair pathway used to repair double-strand breaks that can occur throughout all cell cycle phases. Conversely to the homologous recombination (HR) pathway, the NHEJ pathway does not need a homologous template at the DNA double-strand breaks ends and therefore NHEJ is an error-prone repair pathway that may cause mutations within the repaired region of the DNA. The NHEJ pathway is well-known to induce indels (i.e., insertions and deletions) mutations that shift the reading frame of the protein (i.e., frameshift mutations), thereby leading to a completely different translated protein from the original one.

Answer:
1 - William Harvey
2 - Galen
Explanation:
Galen, who postulated that blood was produced continuously in the liver and absorbed by the body (not recirculated), served as the Roman emperor's personal physician. For 1500 years, his theories about human anatomy went unquestioned until Harvey's proposal in 1628.
When he discovered that blood is pumped from the heart to the body, and back to the heart, William Harvey had a difficult time getting people to accept his discovery because it went against the ancient teachings of Galen.

a group of plant cells was exposed to radiation, which damaged the chloroplasts and coursed them to lose function. if the mitochondria were unharmed, what would happen to the overall function of the plant cell
Explanation:
First of all the mitochondria is the power house of a cell. Then a chloroplast is one which contains chlorophyll in which photosynthesis takes place.
Plants make use of photosynthesis to synthesize nutrients from carbon dioxide and water. If the chloroplast is damaged that means the plant would wither but it may not likely die since the mitochondria is unharmed.

Opsonins function by Opsonins function by marking or tagging pathogens so phagocytes can find and ingest them. poisoning and killing invading cells, marking or tagging pathogens so phagocytes can find and ingest them, and digesting invading cells directly. poisoning and killing invading cells. digesting invading cells directly. poisoning and killing invading cells and marking or tagging pathogens so phagocytes can find and ingest them.
Answer:
The correct answer is: marking or tagging pathogens so phagocytes can find and ingest them.
Explanation:
Opsonins are proteins of great importance in our immune system that can intervene in the innate and the adaptative immune response thanks to the complement system.
Opsonins can recognize pathogens or diseased cells and bind to their surface molecules, thus marking them for other cells (particularly phagocytes such as macrophages and neutrophils) to phagocyte (eat) them. This process is hugely important in removing potential threats and non-functioning cells.
