Answer:
hi buddy, here's your answer
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.
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.

What type of growth is characterized by a consistent increase in growth rate?
A) Exponential growth B) Carrying capacity growth
C) Logistic growth D) Stable growth
Answer:
It is Exponential growth.
Explanation:
Carrying capacity is the most amount of each population that a ecosystem can hold.
Logistic growth is not consistent.
The type of growth that is significantly characterized by a consistent increase in growth rate is known as Exponential growth. Thus, the correct option for this question is A.
What is Exponential growth?Exponential growth may be characterized as a type of growth that is followed by continuous breeders. The population of continuous breeders contains more individuals than a similar population breeding annually.
Some examples of this growth pattern include insects, humans, bacteria, internal parasites, larger plants, and animals. In this type of growth pattern, the value of carrying capacity must be reached fat as compared to other growth patterns like logistic growth.
Therefore, exponential growth is a type of growth that is significantly characterized by a consistent increase in growth rate. Thus, the correct option for this question is A.

How do limiting factors impact local ecosystems?
A)Limiting Factors prevent populations in ecosystems form growing any larger. If any of the limiting factors change, animal and plant populations change, too.
B)Limiting factors do not prevent populations in ecosystems from growing any larger. If any of the limiting factors change, animal and plant populations do not change, too.
C)Limiting factors can never impact ecosystems.
D)As biodiversity of an ecosystem increases, the ability to withstand environmental stress due to the loss of a single species or group also increases, improving the sustainability of the ecosystem.
Answer:
limiting factors like the availability of food, water, shelter and space can change animal and plant populations. Other limiting factors, like competition for resources, predation and disease can also impact populations. ... Sometimes a population will grow too large for the environment to support.

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.

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.

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.
