what was the path of darwin’s voyage
Answer:
In 1831, Charles Darwin received an astounding invitation: to join the HMS Beagle as ship's naturalist for a trip around the world. For most of the next five years, the Beagle surveyed the coast of South America, leaving Darwin free to explore the continent and islands, including the Galápagos.
Explanation:
Most of the trip was spent sailing around South America. There Darwin spent considerable time ashore collecting plants and animals. Darwin filled notebooks with his observations of plants, animals, and geology. The trip was an almost five-year adventure and the ship returned to Falmouth, England, on October 2, 1836.

1. State Mendel's Law of Inheritance.
2. What are the two alleles for flower color in snapdragon?
3. State the Law of Non-Mendelian Inheritance in snapdragon.
Answer:
1
Explanation:
he was able to find chromosomes in plants
Gregor Mendel's research on pea plants led him to the fundamental ideas of inheritance. He came to the conclusion that genes are inherited as distinct, paired units from each parent.
What is Non-Mendelian Inheritance?
Inheritance of features with a more complicated genetic base than one gene with two alleles and total dominance is referred to as non-Mendelian inheritance.
One allele may not always be dominant over another, resulting in a phenotype that falls between the two parents in certain people.
Incomplete dominance is the name given to this inheritance pattern. Snapdragon flowers, for instance, exhibit partial dominance.
When both alleles are present at the same time, this pattern of inheritance is referred to as partial dominance, since neither allele is totally dominant over the other.
Therefore, red and white snapdragons cross to produce exclusively pink progeny.

Answer:....cells in the hormone erythropoietin (EPO) I think I’m not rly good with this I’m just helping
Explanation:
Answer:
Red blood cell (RBC) production (erythropoiesis) takes place in the bone marrow under the control of the hormone erythropoietin (EPO). Juxtaglomerular cells in the kidney produce erythropoietin in response to decreased oxygen delivery (as in anemia and hypoxia) or increased levels of androgens.
How can a star be extremely hot like Alpha Canis Majoris (4 times hotter than our sun) but give off so little light (only 2% of our sun’s light)?
It's on Earth Science.
Answer:
this is due to the fact that stars are suns of other galaxy as we know that we have about a million galaxies in space. the earth is located in the milky way galaxy so these stars are about a 150 billion kilometres from earth
Solar radiation is a broad word for the electromagnetic radiation that the sun emits. It is also sometimes referred to as the solar resource or just sunshine. A multitude of devices can be used to collect solar radiation and transform it into useful forms of energy, such as heat and electricity.
How much of the Sun do we actually see?Sunlight at Earth's surface is roughly 42 to 43 percent visible (400 to 700 nm), 52 to 55 percent infrared (above 700 nm), and 3 to 5 percent ultraviolet in terms of energy (below 400 nm).The Sun always emits the same amount of energy. Insolation refers to the incoming solar radiation. Seventy percent of solar energy makes it to the planet.99.8% of the mass in our solar system is found in the Sun. Everything, from tiny Mercury to the gas giants to the Oort Cloud, 186 billion light-years away, is kept in place by its gravitational attraction.What would occur if our distance from the Sun increased by 10%?More radiation, ultraviolet rays, heat, and other rays would be directed at our atmosphere. It would be impossible to live. According to my projection, the global average temperature would increase from 16 C to 65 C. (149 Fahrenheit). This would be high enough to prevent most life from existing, yet low enough to prevent water from boiling.The solar system itself, the Sun Between 99.8 and 99.9 percent of the mass of the solar system is found in the Sun. The remaining matter is distributed among the planets and their satellites, asteroids, comets, and the gas and dust that surrounds our star.To learn more about Solar radiation, Refer:

Which description of skeletal cartilage is incorrect
Fibrocartilages are able to withstand both pressure and stretch.
Costal cartilages reinforce airways and support the external nose.
Elastic cartilages are able to tolerate repeated bending.
Articular cartilages cover the ends of most bones at moveable joints.
Costal cartilages are said to be at the anterior extreme of a rib cage. Their function is to give the ribcage a flexible structure and connect the ends of the ribs to the sternum. Respiratory cartilages are present in the Trachea and are responsible for flexible inhalation and exhalation thereby reinforcing airways and providing support to the structure of the nose.

atmospheric carbon?
Although the diagram is missing in this question, we can confirm that two major sources of atmospheric carbon are the use of fossil fuels and the natural ocean-atmosphere exchange.
What sources add carbon to the atmosphere?The most harmful of the sources mentioned is the one caused by humans. The burning of fossil fuels such as the oil we use to power cars and other motor vehicles adds tons of carbon into the atmosphere every day.
On the other hand, there are also naturally occurring sources for atmospheric carbon, such as the ocean or the respiration process of animals.

Solar energy is need for both process
Solar energy is needed for photosynthesis and chemical energy is need for
cellular respiration
Answer:
Option D.) Solar energy is needed for photosynthesis and chemical energy is need for cellular respiration, should be your answer here.

The sun gives solar energy to the plant, which is how photosynthesis happens, and chemical energy is needed in order to form glucose (sugar) in cellular respiration.
The statement best describes the energy needed for photosynthesis and cellular respiration to take place is photosynthesis and chemical energy is need for the process.
What is the first step of cellular respiration?Glycolysis has been known as the first step of the cellular respiration. During this process molecules of the glucose break down in order to form the pyruvate molecules including 2 ATP molecules.
During the process of glycolysis there has no requirement of the oxygen. Therefore, the process has been known as the anaerobic process. During the process of the glycolysis glucose which has been converted into the pyruvic acid and energy has been released for the formation of the high energy molecule.
The process of photosynthesis takes place in the green plants and during the process of photosynthesis green plants prepare their own food in the presence of sunlight and the process is known as photosynthesis. During this process heat energy converted into chemical energy.
