q1: Which season is taking place in the Northern Hemisphere in Position 1?
q2:Which season is taking place in the Northern Hemisphere in Position 2?
q3:Which season is taking place in the Northern Hemisphere in Position 3?
q4:Which season is taking place in the Northern Hemisphere in Position 4?
The seasons of the Northern hemisphere shown in the different positions are as follows: Position 1: Winter, Position 2: Spring, Position 3: Summer, and Position 4: Fall.
What controls season cycle?The season cycle is controlled by the rotation of the Earth on its own axis and the revolution of the Earth around the sun cause changes in the season of different hemispheres on the Earth and the day and night cycle. The change in seasons is mainly caused by the rotational tilt of the Earth on its axis when it revolves around the sun in the Universe.
The different seasons which are shown in the diagram are as follows:
Q1 is winter season because the Sun’s light does not hit the northern hemisphere as much as the other seasons.
Q2 is spring season because the Sun's light is partially hitting the northern hemisphere but not fully.
Q3 is summer season because the Sun's light is completely or fully hitting the northern hemisphere and thus increased temperature.
Q4 is fall season because the Sun's light is partially falling on the northern hemisphere and spring is taken during this time.

HELP ME ASAPPP- A piece of mRNA had the code AUU UGC AAC CAU. Which amino acid are coded in this strand
Answer:
isoleucine, cysteine, asparagine, histidine
Explanation:
The following table shows the currently accepted half-life values for four parent isotopes.
Parent Isotope Currently Accepted Half-Life Values
Uranium-238 4.5 billion years
Uranium-235 704 million years
Thorium-232 14.0 billion years
Rubidium-87 48.8 billion years
Potassium-40 1.25 billion years
Samarium-147 106 billion years
Earth is approximately 4.5 billion years old. Given this information and the data in the table, which of the following isotopes could today contain less than 50 percent of its parent isotope?
Rubidium-87
Thorium-232
Uranium-235
Uranium-238
Answer:
The amount of substance present in a certain sample can be calculated through the equation,
A(t) = A(o)(0.5)^(t/h)
where At is the amount now, Ao is the original amount, t is the number of years and h is the half-life.
For a substance to at most 50% of the original amount, we get the half-life value.
At/Ao = 0.5 = 0.5^(4.5/h)
h = 4.5 billion.
ok the answers are simple:
Parent Isotope Currently Accepted Half-Life Values: is the first one uranium-238 4.5 billion years
Earth is approximately 4.5 billion years old. Given this information and the data in the table, which of the following isotopes could today contain less than 50 percent of its parent isotope: uranium- 238

i need help reasonably defining 10 parts of a cell.
parts of the cell: cell membrane, nucleus, cytoplasm, endoplasmic reticulum, ribosomes, golgi bodies (or golgi apparatus), lysosomes, cytoskeleton, mitochondria, and vacuoles
Muscle is soft tissue. Many elastic fibers make up the muscles. The body has over 600 muscles. Different muscle types have different tasks. Some muscles help you run, jump, and perform delicate tasks like threading a needle. Other muscles enable breathing and food digestion. Your heart is a hard working muscle that beats thousands of times a day. There are three types of muscle tissue in the body. They are:
Skeleton: As part of the musculoskeletal system, these muscles work in concert with bones, tendons and ligaments. Tendons attach skeletal muscles throughout the body to bones. Together they support the weight of the body and aid movement.
You control these voluntary muscles. Some muscle fibers contract rapidly, expending short bursts of energy (fast-twitch). Others move slowly like this: B. Back muscles that help with posture.
Heart: These muscles line the walls of the heart. They help the heart pump blood through the cardiovascular system. They do not control the heart muscle. Your heart tells them when to contract.
Smooth: These muscles line organs such as the bladder, stomach, and intestines. Smooth muscle plays an important role in many body systems, including the female reproductive system, the male reproductive system, the urinary system, and the respiratory system.
These muscle types work without you thinking. They perform important tasks such as moving waste products through the intestines and helping the lungs expand when breathing.

Eye color is determined by two alleles B and b. B is for dominant for brown eyes and b is recessive for blue eyes. What is the possible genotype of a person with brown eyes? (more than one possible answer)
a. Bb
b. BB
c. bb
Pls be serious when answering this question.
Answer:
A and B
Explanation:
Because B Brown is dominant It will show up in a Bb instead of b Blue. Brown is dominant over blue.
If ther genotype is BB then Brown is the only color that will show.
So A and B will be the answer.
Various gene variations affect a person's eye color. Most of the genes related to eye color make, transport, or store melanin, a pigment. Eye color is directly influenced by the amount of melanin present in the iris's outermost layers. Thus, option A, B is correct.
What effect of genotype on eyes color?Even while eye color is frequently thought of as a simple Mendelian feature, additional research.
Eye color does not follow the conventional hierarchical patterns of heredity, according to observation. Variations in eye color exhibit both epistasis and partial dominance.
Due to B Brown's dominance, it will manifest as a Bb rather than b Blue. Brown is dominant over blue.
Therefore, If their genotype is BB, then Brown is the only color that will show.

B Mesohippus
C Hyracotherium
D Miohippus
Answer: I think the answer would be D miohippus
Explanation:
Miohippus would be found in the uppermost layer of rock. Therefore, option (B) is correct.
What is Miohippus?Miohippus is an extinct genus of early horse that lived in North America during the Miocene epoch, around 23 to 5 million years ago. It was a small, three-toed horse that was slightly larger than its predecessor, Mesohippus.
Miohippus had a relatively short face, with a long, narrow skull and teeth that were adapted for grinding tough vegetation. It is believed that Miohippus was the ancestor of the modern horse, and that its evolution was characterized by an increase in size, a reduction in the number of toes, and changes in the shape of the skull and teeth that allowed for a more efficient grazing diet.

Organisms with an internal backbone, also known as a vertebra, are referred to as vertebrates. They have a robust bone skeleton that anchors muscle and supports the body's tissue.
What are the Five Vertebrate Groups?Vertebrates can be divided into five main categories. The following is included in this:
Mammals - Mammals typically have hair or fur on their body and warm blood. Mammals give birth to live young, which their mothers nourish with milk. Humans are mammals, but lions, cats, and sheep are other examples of mammals.Birds have beaks, feathers, wings, and two legs. They also have warm-blooded bodies. On land, they lay their eggs.Fish – In water, fish both mate and lay their eggs. They lack lungs and have gills in place of legs.Reptiles are land- and water-based animals. They are cold-blooded and have scales. This indicates that they require a warm environment because they are unable to stay warm on their own. On land, they lay their eggs. Lizards, snakes, and turtles are some examples of reptiles.Amphibians - Although they can live both on land and in water, amphibians only lay their eggs in the latter. They have smooth skin and a chilly blood. Among amphibians are salamanders, toads, and frogs.To Learn more About vertebrates refer to:

If you walk barefoot on asphalt, energy is transferred by which process?
If you walk barefoot on asphalt, energy is transferred primarily by conduction. When walking barefoot on asphalt, heat energy from your body is transferred to the asphalt through direct contact (conduction), making the surface warm.
Conduction is the process of heat transfer through direct contact between objects or substances. When your bare feet touch the asphalt surface, the heat energy from your body is transferred to the asphalt through direct contact. Asphalt is a good conductor of heat, so it quickly absorbs the heat from your feet, making the surface warm.
Convection involves the transfer of heat through the movement of fluids, which is not the case when walking on asphalt. Radiation is the transfer of heat through electromagnetic waves, but in this situation, direct contact between your feet and the asphalt is the primary method of energy transfer.
Thus, when you walk barefoot on asphalt, the majority of the energy is carried by conduction.
