Answer:
Sheep and Salamander
Salamander organisms undergo Carnegie stages.
What happens in Cranegie stage?In Embryology, the Carnegie Stages are a set of 23 stages used to describe the developmental chronology of a vertebrate from fertilisation to the point it becomes a foetus.
The stages are delineated through the development of structures, not by size or the number of days of development, and so the chronology can vary between species, and to a certain extent between embryos.
In the human being only the first 60 days of development are covered; at that point, the term embryo is usually replaced with the term fetus. CS6-10 is a large installation that show the early human embryo transform from a flat disk of cells.

Nonvascular plants have flagellated sperm that must swim to find the eggs. Why is this a limitation for land plants
Nonvascular plants have flagellated sperm that must swim to find the eggs this is because the land plants have pollinaters which help in pollination.
The transfer of pollen grains from anther to stigma of a flower is called pollination. Pollen grains are transferred mainly by wind, water, insects and animals. They are called pollinating agents.
The agents or media which can transfer the pollen grains for pollination are called the agents of pollination. Air, water, animals and insects are the common agents of pollination. Pollination by air: Light and dry pollen grains are carried by air to the other plants.

The hormone that increases the heart rate and blood pressure in an emergency situation and triggers the fight or flight response is epinephrine, also known as adrenaline.
Epinephrine is a hormone and neurotransmitter that is produced by the adrenal glands and certain neurons. It's sometimes referred to as adrenaline. Epinephrine is a vital component of the body's fight or flight response to stress. In response to a stressful situation, the body produces epinephrine, which increases heart rate, blood pressure, and respiratory rate to provide the body with more energy and oxygen.
This helps the body to respond to the threat, either by fighting or fleeing from it.In addition to this, Epinephrine is a medication that is used in emergency situations to treat severe allergic reactions, asthma attacks, and cardiac arrest. It works by narrowing blood vessels and raising blood pressure, making it easier for the heart to pump blood.

3)Convection transfers thermal energy.
4)Convection transfers potential energy.
5)Convection occurs until all of the fluid is at the same temperature.
6)Convection occurs only one time, no matter the temperature.
Convection occurs in liquids and gases. Convection transfers thermal energy. Convection occurs until all of the fluid is at the same temperature. The statements that best describe convection are 2, 3, and 5.
Convection is a method of energy transfer that occurs in fluids, which are substances that can flow, such as gases and liquids.
Convection occurs when warmer portions of a fluid rise and cooler portions sink. Convection transfers thermal energy from hotter to colder areas in a fluid.
In convection, the motion of the fluid itself transfers heat, not just the movement of heat through the fluid (as in conduction).
Therefore, convection occurs until all of the fluid is at the same temperature. As a result, convection plays an important role in the movement of heat in the atmosphere and oceans.

What would be the physiological explanation for why urine volume might increase after drinking water?
Drinking more water causes excess fluid content in the blood that will be eliminated in the form of urine.
Water is absorbed in the various parts of the digestive system into the blood. This fluid in the blood is further reabsorbed by the kidneys in the structures called nephrons. These nephrons filter the blood leaving away the molecules which are larger and of higher atomic weight.
The filtrate formed by the nephrons is known as glomerular filtrate and this passes on from the kidney to the urinary bladder. The filtrate consists of water along with wastes and salts from the blood. Thus, kidneys purify the blood and the urinary bladder lets it out through urination.

The intensity of sunlight on Earth is affected by
A.) the mass of Earth
B.) the speed of Earth
C.) the number of rotations of Earth
D.) the curved surface of Earth
Answer:
The correct answer is D.) the curved surface of Earth.
Explanation:
The intensity of sunlight on Earth is affected by the curved surface of Earth, which causes the sunlight to spread out over a larger area. As a result, the intensity of sunlight is less at any given point on Earth's surface than it would be if Earth had a flat surface. This also explains why the poles receive less sunlight than the equator, as sunlight is spread out over a larger area near the poles due to the curvature of the Earth.
Factors such as the mass of Earth, the speed of Earth, and the number of rotations of Earth do not directly affect the intensity of sunlight on Earth.

which observation is inaccurate regarding bacterial cell growth? question 1 options: each bacterium plated will represent a colony-forming unit. observation of a turbid culture is indicative of bacterial growth. agar is used as a solidifying agent in some types of media. bacteria growing in a liquid culture will generate colonies.
The inaccurate observation regarding bacterial cell growth is that bacteria growing in a liquid culture will generate colonies. This observation is inaccurate because bacterial growth in a liquid culture does not result in colony formation.
What is bacterial cell growth? Bacterial cell growth is the increase in the number of cells, which occurs by cell division. Bacteria can grow and reproduce in a variety of environments, including liquid or solid media. When bacteria grow on a solid surface, each bacterium plated will represent a colony-forming unit. When bacteria grow in a liquid medium, they will cause the medium to become turbid (cloudy), indicating bacterial growth.
However, bacterial growth in a liquid culture will not generate colonies, making the option "bacteria growing in a liquid culture will generate colonies" the inaccurate observation regarding bacterial cell growth. This is because liquid cultures do not have a solid surface for bacterial growth, which is necessary for colony formation. Hence, this observation is inaccurate.

Which organ is responsible for storing bile?
Pancreas
Gallbladder
Stomach
Liver
The organ responsible for storing bile is the gallbladder. So, the correct choice is Gallbladder.
The gallbladder, located beneath the liver, is the organ responsible for storing bile. Bile is a greenish-yellow fluid that aids in the digestion and absorption of fats.
It is produced by the liver and then transported to the gallbladder for storage. When we consume a meal containing fats, the gallbladder contracts and releases stored bile into the small intestine through the bile ducts. Bile helps in emulsifying fats, breaking them down into smaller droplets, which increases the surface area for enzymes to act upon. This process enhances the absorption of fats and fat-soluble vitamins in the small intestine.
The storage and controlled release of bile by the gallbladder ensure that an adequate amount of bile is available for the digestion and absorption of fats whenever required.
