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.

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.

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.

A.Chromosomes
B.Fossils
C.Genes
D.Mutations
Answer:
A
Explanation:
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 -
LG Lg lG lg
LG LLGG LLGg LlGG LlGg
Lg LLGg LLgg LlGg Llgg
lG LlGG LlGg llGG llGg
lg LlGg Llgg llGg llgg
Offspring with long wings and brown color – LLgg, Llgg , two out of 16
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.

Group of answer choices
True
False
Answer:
true
Explanation:
Mutations in genes cause
A. Variation
B. Competition
C. Reproduction
Answer:
Hello There the Correct answer is A. Variations.
Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).

An energy harvesting process is depicted above. On which branch of the tree of life would organisms be able to perform this process?
A)On all branches of the tree, as glycolysis is a universal, energy-releasing process for cells. B)Only on the branch with Eukarya, as eukaryotes are the only organisms that contain mitochondria. C)Only on the branch with Archaea, as extremophiles are the only organisms that evolved the ability to process pyruvate. D)Only on the branch with Bacteria, as prokaryotes are the only organisms that contain enzymes necessary to perform this process
A: on all branches of the tree, as this is a common structure and process among all species

Answer:
DNA plays a role in the evolution of a species. Chromosomal DNA helices don't usually interact with each other. However, through the process of genetic recombination, segments of different chromosomes swap places with each other, creating new sequences of genetic material.

Which of the following is not a macromolecule?
a
carbohydrates
b
plastics
c
proteins
d
metals
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.

Answer:
No, bottled water cannot go bad.
Explanation:
It is impossible for any sort of water to "expire". But, when in the bottle for to long, the plastic does become dangerous. The bottle begins to leak chemicals into the water. This doesn't make the water toxic, but it can alter the taste of your water.
