Answer:
We define seven hallmarks of cancer: selective growth and proliferative advantage, altered stress response favoring overall survival, vascularization, invasion and metastasis, metabolic rewiring, an abetting microenvironment, and immune modulation, while highlighting some considerations for the future of the field.
In primary mutant screens, A) mutant flies are identified by morphology and then the mutant genes are isolated and studied. B) mutant flies are created by RNAi using random RNA sequences and then the genes affected identified. C) mutant flies are created by gain-of-function expression of random genes. D) two mutant flies are mated to determine if there is an effect on morphology.
Answer:
A) mutant flies are identified by morphology and then the mutant genes are isolated and studied.
Explanation:
The visualization of mutant flies is done with an experiment, where drosophila flies, also known as fruit flies, are captured and placed in closed bottles. The bottles have a mixture of banana and agar so that the flies can feed for a period of 15 days. During these 15 days, the flies made several crosses and over time, it will be possible to identify the appearance of mutant flies as a result of the number of crosses made inside the bottle. The mutant flies will be identified when the researcher is able to observe flies with legs, eyes and wings in different numbers than what is presented in a normal fly.
After being identified by their different morphology, the mutant flies will have their mutant genes isolated and studied.

Why is carbon considered tetravalent?
A. Since it has four electrons in its outermost orbital, it needs four more electrons to complete its octet.
B. Since it has two electrons in its outermost orbital, it needs four more electrons to complete its octet.
C. Since it has four electrons its outermost orbital, it can donate four electrons to complete its octet.
Answer:
The word tetravalent means having a valence of four because of the prefix - tetra. Carbon is considered tetravalent because it has four electrons in its outermost orbital. In order to follow the octet rule, it has to share four other electrons with other atoms. Thus, the answer is the first choice.

6.The signal strength, or "loudness," of a signal over time at different frequencies contained in a specific waveform is visually represented in a spectrogram.
What purpose does a spectrogram serve?The signal strength, or "loudness," of a signal over time at different frequencies contained in a specific waveform is represented visually in a spectrogram. One can observe how energy levels change over time in addition to determining whether there is more or less energy, for instance, at 2 Hz vs. 10 Hz.
How should a spectrogram be read?The vertical axis or y-axis of the spectrogram view shows frequency in Hertz, the horizontal axis or x-axis denotes time (exactly like in the waveform display), and brightness denotes amplitude. The sine wave is represented by the bright orange curve while the background is black, which represents silence.

which of the following structures in a plant cell is responsible for the production of food
Answer:
chloroplastExplanation:
Chloroplasts are specialized organelles found only in plants and some types of algae. These organelles carry out the process of photosynthesis, which turns water, carbon dioxide, and light energy into nutrients from which the plant can obtain energy. There can be over one hundred chloroplasts in certain plant cells.
Chloroplasts are disk-shaped organelles that are surrounded by a double membrane. The outer membrane forms the external surface of the chloroplast and is relatively permeable to small molecules, allowing substances entry into the organelle. The inner membrane lies just beneath the outer membrane and is less permeable to external substances.
Between the outer and inner membrane is a thin intermembrane space that is about 10-20 nanometers wide. The center of the chloroplast that is enclosed by the double membrane is a fluid matrix called the stroma (you can think of this like the cytoplasm of the chloroplast).
Within the stroma, there are many structures called thylakoids, which look like flattened disks. Thylakoids are stacked on top of one another in vascular plants in stacks called grand. Thylakoids have a high concentration of chlorophyll and carotenoids, which are pigments that capture light energy from the sun. The molecule chlorophyll is also what gives plants their green color.
2. Which is probably most responsible for the
formation of this landform? sc.6.E.6.1
wind
water
plants
animals
According to the given statement wind is probably most responsible for the formation of this landform.
What is Land formations?The four main categories of landforms are plains, plateaus, hills, and mountains. Landforms include things like rivers, lakes, buttes, canyons, basins, and valleys.
An earthly feature that is a part of the terrain is referred to as a landform. There are four main categories of landforms: mountains, hills, plateaus, and plains. Valleys, buttes, canyons, and basins are examples of minor landforms.
Mountains and hills can be pushed up by the Earth's tectonic plate movement. Valleys and canyons can be formed by erosion brought on by water and wind. The duration of these procedures can reach millions of years.
Underwater mountain ranges and seabed basins are examples of landforms that can exist. In the South Pacific lies the Mariana Trench, the world's deepest landform.

Explanation:
Plate motion occurs as a consequence of convection in Earth's
crust
mantle
core
The movement of these tectonic plates is most likely caused by convection currents in the molten rock beneath the crust of the Earth. The immediate consequences of this tectonic shift are earthquakes and volcanic eruptions.
What effect does this plate movement have?Mountains will grow where plates converge or push together, and continents will split and oceans will form when plates pull apart or diverge. The Earth's geography has changed significantly over the span of millions of years as a result of the continents passively drifting with the plates.
What causes the mantle's plates to move?The plates fit tightly against one another and lie on the heated, molten rock of the Earth's mantle like fragments of a split shell.

The state of a medium helps determine the speed of sound passing through medium
True. The speed at which sound travels through a medium is determined by the properties of that medium.
What do you mean by sound?
Sound is a type of energy made by vibrations that travel through the air or another medium, like water. It is sensed by our ears and interpreted by our brains. Sound is made up of waves that have different frequencies, which determine the pitch and loudness of a sound.
Factors such as temperature, pressure, composition, and density can all affect the speed of sound in the medium. For example, sound travels faster through warmer air than through colder air, and faster through denser materials than through less dense materials.
Hence, the statement is True.

The plankton as a carbon sink will be greater than expected, but the plankton as a carbon source
will be less than expected.
O The plankton as a carbon sink and as a carbon source in the area will be greater than expected.
This information might be used to draw the conclusion that there will be fewer plankton in the region than is typical both as a carbon source and sink, hence B is the appropriate response to this question.
What is phytoplankton?The kind of organisms that live in watery habitats are known as phytoplankton.
These species are autotrophic in nature and are the producers of this ecosystem. These creatures share a characteristic with terrestrial plants in that they both contain chlorophyll.
Therefore, if the phytoplankton population falls in the coming year, it means that the region's carbon supply and sink will be less than anticipated.
