Why do fish and frogs lay eggs in hundreds whereas a hen lays only one egg at a time?
Answers
Answer:
bc there eggs are tinnier then a hens egg
Explanation:
Answer:
Animals like frogs and fish lay hundreds of eggs and release millions of sperms. But the entire eggs do not get fertilized and develop into new individuals. This is because the eggs and sperms get exposed to water movement, wind and rainfall. Also, there are other animals in the pond which may feed on eggs. Thus, production of large number of eggs and sperms is necessary to ensure fertilization of at least a few of them.
What does the immune system protect the body against?
Answers
Anatomy of the immune system
There are two main parts of the immune system:
The innate immune system, which you are born with.
The adaptive immune system, which you develop when your body is exposed to microbes or chemicals released by microbes.
These two immune systems work together.
The innate immune system
This is your child's rapid response system. It patrols your child’s body and is the first to respond when it finds an invader. The innate immune system is inherited and is active from the moment your child is born. When this system recognizes an invader, it goes into action immediately. The cells of this immune system surround and engulf the invader. The invader is killed inside the immune system cells. These cells are called phagocytes.
The acquired immune system
The acquired immune system, with help from the innate system, produces cells (antibodies) to protect your body from a specific invader. These antibodies are developed by cells called B lymphocytes after the body has been exposed to the invader. The antibodies stay in your child's body. It can take several days for antibodies to develop. But after the first exposure, the immune system will recognize the invader and defend against it. The acquired immune system changes throughout your child's life. Immunizations train your child's immune system to make antibodies to protect him or her from harmful diseases.
The cells of both parts of the immune system are made in various organs of the body, including:
Adenoids. Two glands located at the back of the nasal passage.
Bone marrow. The soft, spongy tissue found in bone cavities.
Lymph nodes. Small organs shaped like beans, which are located throughout the body and connect via the lymphatic vessels.
Lymphatic vessels. A network of channels throughout the body that carries lymphocytes to the lymphoid organs and bloodstream.
Peyer's patches. Lymphoid tissue in the small intestine.
Spleen. A fist-sized organ located in the abdominal cavity.
Thymus. Two lobes that join in front of the trachea behind the breastbone.
Tonsils. Two oval masses in the back of the throat.
How do antibiotics help fight infections?
Antibiotics can be used to help your child's immune system fight infections by bacteria. However, antibiotics don’t work for infections caused by viruses. Antibiotics were developed to kill or disable specific bacteria. That means that an antibiotic that works for a skin infection may not work to cure diarrhea caused by bacteria. Using antibiotics for viral infections or using the wrong antibiotic to treat a bacterial infection can help bacteria become resistant to the antibiotic so it won't work as well in the future. It is important that antibiotics are taken as prescribed and for the right amount of time. If antibiotics are stopped early, the bacteria may develop a resistance to the antibiotics and the infection may come back again.
Note: Most colds and acute bronchitis infections will not respond to antibiotics. You can help decrease the spread of more aggressive bacteria by not asking your child’s healthcare provider for antibiotics in these
Could anybody help me on this please

Answer:
The term genotype refers to the genetic characteristics of an individual. Many genes have different variations, which are called alleles. As we inherit genes from both of our parents, we inherit one allele from each of them. The combination of alleles we possess is in fact our genotype.
The term phenotype refers to our physical characteristics. They are heavily influenced by our genotype, but they can also be affected by environmental factors (unlike the genotype).
As an example of genotype, we can mention eye color. Brown eyes are a result of dominant alleles (B), while blue eyes are a result of recessive alleles. If a person has one (Bb) or two dominant alleles (BB), their eyes will be brown, and if they have both recessive alleles (bb), their eyes will be blue.
As an example of phenotype, we can mention skin color. The amount of melanin we produce will depend on our genotype. A person whose skin cells produce more melanin will have darker skin. However, our melanin can start getting darker after longer exposure to UV light, which results in skin darker than what is dictated by our genotype.

In sex-linked traits, sons get their traits from the female.
True
False
Answers
Answer:
False
Explanation:
A sex-linked is any phenotypic trait associated with one or more genes located on sex chromosomes, i.e., on the X chromosome and/or the Y chromosome. In humans, females have two X chromosomes, whereas males have one X chromosome and one Y chromosome. In humans, sex-linked traits are often associated with recessive diseases caused by mutations on the X chromosome, although there are exceptions to this rule. In consequence, if a disease is associated with a mutation in the X chromosome, males will have more chances to be affected because males have a single copy of the X chromosome.

What are the interacting spheres of the earth and what is cycled between these spheres?
Answers
Answer: The Earth's Carbon Cycle is the biogeochemical exchange of carbon between the earth's five main physical “spheres”—atmosphere, biosphere, pedosphere, hydrosphere and lithosphere.
Explanation:
cause in space spheres is like ice that freezes in outer space
The interaction spheres of the earth are the atmosphere, biosphere, pedosphere, hydrosphere, and lithosphere.
What are interacting spheres?Within the Earth's crust are four interconnected sections known as “spheres”: the lithosphere, hydrosphere, biosphere, and atmosphere. The spheres are so intertwined that a change in one sphere frequently results in a change in one or more of the others.
The Earth's Carbon Cycle is the biogeochemical exchange of carbon between the earth's five main physical “spheres”—atmosphere, biosphere, pedosphere, hydrosphere, and lithosphere.
These four subsystems are referred to as "spheres." They are the "lithosphere" (land), the "hydrosphere" (water), the "biosphere" (living things), and the "atmosphere" (air). Each of these four spheres is subdivided into sub-spheres.
Therefore, the atmosphere, biosphere, pedosphere, hydrosphere, and lithosphere are the earth's interaction spheres.

When an organism excretes waste, can a plant directly use it as fertilizer (nitrogen source)?
Answers
Answer:
Yes, they can use it directly
Explanation:
Nitrogen is an important macronutrient needed by a wide variety of organisms including plants. However, nitrogen occurs/can be found in different compounds, which are mostly not directly usable by plants while some are directly usable.
According to this question, when an organism excretes waste, the nitrogen content of that waste is found as UREA. UREA is an organic compound rich in nitrogen which can be used directly by plants as fertilizer i.e. nitrogen source.
When an organism excretes waste, a plant can directly use it as fertilizer. Therefore, it's true.
It should be noted that nitrogen is an important macronutrient that's needed by several organisms including plants. It is vital for their growth.
Wastes from organisms are allowed on plants and these are vital for their growth. Therefore, in such a case, when an organism excretes waste, the nitrogen content of that waste can be found in the waste and this can be used as fertilizer for the plant.

How does the moon cause tides?
The pull of the moon on Earth causes the water level on the shores to fluctuate.
The moon's gravitational pull acts on Earth.
The moon dries up Earth during different times of the month.
As the moon's gravity pulls on Earth, the ocean water is pulled toward it.
The moon pushes down on Earth and causes the water to rise.
Answers
Answer: 1, 4, 5
Explanation:
The moon always pulls on the tides, and in certain moments like the equinoxes the moon will set a patterned tide for the rest of the month, since the moon is being flung around in earths orbit, its gravity causes it to pull on the most flucuate object on earth: water. And if you have glass of water then put your hand into it you will see how your hand displaces the water.!
