fertilization results in the formation of zygote.
Answer:
zygote
Explanation:
Zygote, fertilized egg cell that results from the union of a female gamete (egg, or ovum) with a male gamete (sperm). In the embryonic development of humans and other animals, the zygote stage is brief and is followed by cleavage, when the single cell becomes subdivided into smaller cells.

Answer:
Metals are not macromolecules. So D is the answer.
Metals are not macromolecules whereas proteins and carbohydrates are macromolecules. Macromolecules are essentially polymers, long chains of atomic sub-units called monomers. Long polymers are present in proteins, carbohydrates, and nucleic acids. They are referred to as macromolecules because of their large size and polymeric nature.
There are four significant classes of natural macromolecules that are constantly found and are fundamental for life. Proteins, nucleic acids, carbohydrates, and lipids (or fats) are all examples of these.

A student in genetics class is studying the inheritance patterns in fruit flies. He is looking at the traits for wing length, long versus short, and colorbrown versus gray. Using a dihybrid cross of two flies that were heterozygous for long wings and brown color. Long wings and Gray are dominant. How many offspring will have long wings and brown color?
Answer:
LLgg, Llgg , two out of 16
Explanation:
Given,
Dominant - Long wings and Gray color
Recessive - Short wings and Brown color
Let the allele for long wings be "L" and the allele for short wings be "l".
Let the allele for brown color be "g" and allele for gray color be "G"
Genotype of parents
LlGg
Gametes of the parent
LG, Lg, lG, lg
Dihybrid cross is between LlGg and LlGg
The offspring produces will be as follows -

State reason(s) why ash should or should not be used in making compost
Answer:
Fireplace ashes for compost can be used to help maintain the neutral condition of the compost. It can also add nutrients to the soil. Decomposing materials in the compost pile can become somewhat acidic and wood ash can help offset this, as it's more alkaline in nature. But Adding too much ash to the pile can be detrimental to the makeup of the compost because of its alkalinity. Ashes tend to raise the soil pH, so you shouldn't use it directly on plants, especially acid-loving ones like rhododendrons, azaleas, and blueberries. Also, in high amounts, wood ash can inhibit plant growth by restricting nutrients, like iron.
Everyone in Squidward’s family has light blue skin, which is the dominant trait for body color in his hometown of Squid Valley. His family brags that they are a “purebred” line. He recently married a nice girl who has light green skin, which is a recessive trait. Use a Punnett square to determine the possibilities that would result if Squidward and his new bride had children.
List the possible genotypes and phenotypes for their children. *
Can i please have a explenation
All their children will have heterozygous genes because squidward is "purebred", or homozygous dominant. His wife has to be homozygous recessive for a recessive trait to show up. Every time you cross a homozygous dominant trait with a homozygous recessive trait, you will get heterozygous kids. This means all of them will have light blue skin.

Assume that producers in an ecosystem have 1,000,000 kilocalories of energy. How much energy is available to primary
consumers?
5. Which trophic level has the greatest biomass?
Therefore, according to this question, if it is assumed that that producers in an ecosystem have 1,000,000 kilocalories of energy; 10/100 × 1,000,000 = 100,000 kilocalories of energy will be available to primary consumers.
WHAT IS BIOMASS:The total biomass of an organism in each trophic level decreases going up. This is due to the lesser energy transferred from one trophic level to the next. As the trophic level increases, lower energy is available to convert into biomass. Hence, the higher the trophic level, the lower the biomass.Therefore, if this is the case, the producers at the first trophic level will contain the greatest biomass which will decrease as the food chain progresses upwards.

People with hemophilia need to have clotting factor proteins injected into their cells throughout their lifetime. Based on what you observed when you added proteins to change Greg’s stripe color, why do you think people with hemophilia constantly need to receive injections of the protein? *
Answer: people with hemophilia constantly need to receive injections of the protein because, hemophilia can causes internal bleeding in severe cases, which can result in the damage of organs and joint. This is because people who have hemophilia lack a specific protein (which is called a clotting factor) that enables blood to clot.
Explanation:
Hemophilia is a hereditary bleeding disorder which is characterized by either decreased, defective or absent production of blood clotting proteins.
The treatments needed will depend on the type of hemophilia and the severity of hemophilia. For example, if you have mild hemophilia (that is relevant clotting factor activity is greater than 5%, but less than normal), you may need treatment only when you are in preparation for a surgery or when you have an injury. However, if you have severe hemophilia that bleed frequently, you may need regular (several times in a month) to help prevent bleeding and help protect your joints from deformity and disability.
