The purpose of weather radar, often referred to as Doppler weather radar, is to locate precipitation, assess its velocity and intensity, and determine the precipitation type, such as rain, snow, or hail. It does this by sending electromagnetic energy pulses into the sky.
Doppler radar may detect the mobility of the rain along the radar beam in addition to the precipitation in a rainstorm (by its reflectivity, or capacity to reflect microwave radiation). To put it another way, it can calculate how quickly hail or rain is travelling towards and far from the radar. The electromagnetic waves used by radar move at a rate of 300,000,000 m/s. A local TV news station's weatherman uses Doppler radar, for instance, to predict storms. A police officer might utilise Doppler radar to gauge the speed of an approaching car as an illustration. Astronomers might use Doppler radar to gauge the speed of a moving star as an illustration.

the eyeless gene is required for eye formation in drosophila. it encodes a homeodomain. a. what would you predict about the biochemical function of the eyeless protein? b. where would you predict that the eyeless gene is expressed in development? c. the small eye and aniridia genes of mice and humans, respectively, encode proteins with very strong sequence similarity to the fly eyeless protein, and they are named for their effects on eye development. devise one test to examine whether the mouse and human genes are functionally equivalent to the fly eyeless gene.
According to the given statement:
a:- Potential use for its protein is as a DNA-binding transcription factor that binds to specific DNA sequences.
b:- It is possible to do gene deletion experiments to see if Drosophila will retain its eyes or go blind.
c:-Transgenic tests can be used to determine whether the Small eye and Aniridia genes function similarly to the fly eyeless gene.
Briefing:In Drosophila, the eyeless gene is necessary for the development of eyes. Given that it encodes for a homeodomain, its protein may have a role as a transcription factor that binds DNA in a specific sequence. In situ hybridization can be used to study the gene's mRNA expression pattern, and immunological methods can be used to study the protein.
A. Since the eyeless gene in Drosophila encodes for a homeodomain, one potential use for its protein is as a DNA-binding transcription factor that binds to specific DNA sequences.
B. As implied by its function, the eyeless gene should be expressed in the Drosophila cells in charge of eye formation. In situ hybridization of the gene's mRNA expression is one potential test to find the gene. The protein can also be seen via a variety of immunological and staining methods. It is possible to do gene deletion experiments to see if Drosophila will retain its eyes or go blind. Additionally, genetic engineering can determine whether the eyeless gene expressed in other organs can result in the creation of eyes.
C. Transgenic tests can be used to determine whether the Small eye and Aniridia genes function similarly to the fly eyeless gene. Since both of these function as master switches for the genes that create eyes, it is possible to transfer the mouse Small eye gene into Drosophila to observe whether it is expressed. These, however, are simply Drosophila eyes and not comparable to mouse eyes.

dysregulated crtc1 activity is a novel component of pge2 signaling that contributes to colon cancer growth
The correct answer is CRTC1 its significance of its dysregulation in colon cancer because of its predominant expression in the brain .
CRTC1 transcriptional activity is mediated by EP1 and EP2 receptor signalling, as well as subsequent calcineurin and protein kinase A activation. In colon cancer cell lines, in vitro CRTC1 loss of function was associated with decreased viability and cell division rate, as well as increased chemotherapy-induced apoptosis in response to PGE2. CRTC1 stable overexpression, on the other hand, significantly increased colonic xenograft tumour growth, demonstrating the role of CRTC1 signalling in colon cancer progression. The discovery of the transcriptional programme activated by increased CRTC1 expression during colonic carcinogenesis revealed several notable pro-tumorigenic CRTC1 target genes, including NR4A2, COX2, amphiregulin (AREG), and IL-6. Finally, we show that CRTC1-induced COX2, AREG, and IL-6 promoter activities are dependent on functional AP1 and CREB transcriptional partners.

Why don't birds get electrocuted when they land on an electric wire? Pls answer, will give 20 points.
A bird just sitting on a wire doesn't touch the ground, or anything in contact with the ground, so electricity stays in the power line. However, if a bird were to touch a power line as well as equipment or other metal that is grounded, it could potentially give electricity a path to the ground and the bird could be shocked.
When a bird is perched on a single wire, its two feet are at the same electrical potential, so the electrons in the wires have no motivation to travel through the bird’s body. No moving electrons means no electric current. The bird is safe, however if that bird stretches out a wing or a leg and touches a second wire, especially one with a different electrical potential, it will open a path for the electrons — right through the bird’s body.
Power lines carry alternating currents or AC where the electric current regularly changes direction. Over time the voltage alternates between positive and negative indicating the direction of voltage flow. Voltage is the difference in charge between two points, whilst current, measured in amperes, or amps, is the rate at which the charge is flowing. The number of cycles per second is measured in Hertz (Hz) and average power lines have a frequency of 50 Hz. Because the voltage in the wire is constantly changing, the voltage of a bird sitting on a wire is also changing. In other words, the bird is constantly being charged and discharged through its feet.
The other thing we need to think about is the capacitance of the bird. This is the ability of the bird to collect and store electric charge. Because birds are very small and shaped a bit like spheres, they can’t store much electric charge. In fact, when a bird sits on a 50 Hz power line it can only carry a current in the order of microamps (μA), or 0.00000001 amps.
So although the bird does have a current running through its body, it is too small to electrocute it or even give it an electric shock. For comparison, a current of about 10 milliamps (0.01 amp) is enough to produce a painful shock in humans, and electrocution is possible from about 50 milliamps. We don’t know whether birds perched on power lines can feel the current going through their bodies. Perhaps they enjoy the buzzing sensation that they may be feeling and perhaps this explains why you don’t often see big birds, with a larger capacity, sitting on power lines.
A bird is also made of cells and tissues. These cells and tissues do not provide the electricity in the wire with an easier route to travel than the one it is already on. Because a bird's body is not a good conductor of electricity, the electricity essentially ignores the bird on the wire and continues to travel along the copper wiring to its destination. In fact, humans would also be able to not be shocked by a power line if we hung suspended from the power line with both of our hands on the line and no other grounding objects around us.
Answer:
bird's don't get electrocuted when they land on electric wire because their legs don't have blood
Each myosin protein has a globular head that extends outward from the myosin filament. True or false?.
True: Each myosin protein has a globular head that extends outwards from the myosin filament.
Actin and myosin are the two types of proteins found in every kind of muscle cell or tissue. The thick filament is called myosin and the thin filament is called actin. The myosin and actin filament slide over one another to cause movements. The globular head of the myosin proteins in the myosin filament is extended outwards to facilitate the binding of actins.
The myosin filament in muscles consists of two heavy chains and two pairs of light chains. Each heavy chain consists of two parts: globular head region and ∝-helical tail. The globular heads of the myosin bind actin and form a cross-bridge between the thick and thin filaments. Myosin heads also bind and hydrolyze ATP to derive the energy required for sliding.

You’ve now seen that earth’s varying distance cannot be the cause of our seasons. So what is the cause of the seasons?.
Axis of the earth is inclined to its orbital plane. This is the axis around which it spins. This triggers the change of the seasons.
When the earth faces the sun, it is summer in the parts facing the sun. When the axis of the globe is facing away, winter is to be expected. Due to the axis' 23 1/2-degree tilt, the North Pole never points exactly at the Sun, but rather as close as it can during the summer solstice and as far away during the winter solstice. In the midpoint between these two phases, spring, the earth's rotational axis is 90 degrees away from the sun. This shows that there are 12 hours in each day and night on this particular date.Why does our weather matter because of the tilt of the Earth's axis?
Each square centimeter of the earth receives more light (and heat) while the sun is overhead since it is dropping directly on you. Less heat can be absorbed (per square centimeter) when the sun is lower in the sky because the light is more evenly distributed over the earth's surface. The sun is higher when you are on the portion of the earth where the axis points more towards the sun and lower when you are on the part of the earth where the axis points away from the sun because of the tilt of the earth's axis.Hence the answer is inclination of earth's axis.
