HaploidHaploidDiploidTriploidZygoteWhat is double fertilization?Double fertilization is a specific feature of angiosperms involving two male gametes and one female gamete.
In double fertilization, both the female and male gametes are haploid structures i.e. contain one set of chromosome.
One of the haploid sperm cells fertilizes an haploid egg cell, producing a diploid (2n) zygote. However, the other sperm cell fertilizes the polar nuclei, forming a triploid endosperm.
The zygote will eventually develop into the sporophyte (vegetative plant).

Where does frontal inversion occur in the atmosphere and how does it affect us and the environment? Wanther High
Frontal inversion occurs near large water bodies and it leads to a change or invertion in the property of the atmosphere.
What is frontal inversion?Fontal inversion occurs through the impairment of cold air mass in warm air mass.
This leads to a warm air just above the two air masses as cold air distrupt the warm air masses.
Therefore, the frontal inversion takes place near water bodies and it leads to a change or invertion in the property of the atmosphere.

Approximately how many kilograms (kg) of carnivore (secondary consumer) biomass can be supported by a field plot containing 1000 kg of plant material?
About 10 kilograms (kg) of carnivore biomass can be supported by a field plot containing 1000 kg of plant material.
What is an ecosystem?An ecosystem is a self-supporting system consisting of living and non-living components.
In an ecosystem, a carnivore is a secondary consumer.
In energy flow in an ecosystem, 10% of biomass is transferred from primary producer to primary consumer, 10% from primary consumer to secondary consumers.
Thus, 1% of energy is transferred to the carnivore.
1% of 1000 kg = 10 Kg.
Therefore, 10 kilograms (kg) of carnivore biomass can be supported by a field plot containing 1000 kg of plant material.

What is a dominant allele?A dominant allele is a copy of a gene which always appears in every generation.
A pedigree is a chart that shows the inheritance of triats in generations of families.
Based on the pedigree given:
The genotype of the individual #1 is XBXb since the offspring are XBXb and XbYIn the pattern of inheritance, all males receive their X chromosome from their mother.
Se_x-linked pedigrees differ from autosomal pedigrees because the traits are located on the se_x chromosomes.

Is this animal a carnivore or an herbivore? How do its teeth help it obtain food?
Answer:
This animal is a herbivore. The front teeth help it tear off vegetation, and the back teeth help it chew the plants.
Explanation:
A herbivore's back teeth are adapted to help it chew its high fiber plant diet. The front teeth, however, help it actually put the food in its mouth. The picture below shows a typical goat skull (herbivore), and as you can see, it is similar to the one in your problem. So, that skull is one from a herbivore.

Bellwork: of the locations of earthquakes over the past 10 years were plotted on a world map, which of the following would be observed?
A. Earthquakes occur with the same frequency everywhere on Earth.
B. Earthquakes generally occur along the edges of tectonic plates.
C. Earthquakes most frequently occur near the middle of continents.
D. Earthquakes do not seem to occur in any consistent pattern.
Answer: B.
Explanation:
It's not A, because earthquakes happen at different magnitudes depending on how the plates shift beneath them.
It's not C, because tectonic plates are scattered among the earth.
It's not D, since the pattern of earthquakes are dependent on the shifts of tectonic plates.
It's B because tectonic plates are the reason earthquakes happen. Everytime they shift or move, an earthquake occurs. There may be some earthquakes that are not near tectonic plates but the majority are, which is why the question uses the word "generally occur."

Two unlinked loci affect mouse fur color. nn or nn mice are agouti. mice with genotype nn are albino because all pigment production is blocked, regardless of the phenotype at the second locus. at the second locus, the a allele (agouti coat) is dominant to the a allele (black coat). what would be the result of a cross between two agouti mice of genotype nnaa?
The result of a cross between two agouti mice of genotype nnaa are albino offspring because mice with genotype nn are albino (pigment production is blocked by epistasis).
What is epistasis?Epistasis is a genetic phenomenon where the presence of a gene variant alters a phenotype influenced by other genes.
A gene is epistatic when a variant (allele) can alter the expression of another gene in the same signaling pathway.
Epistatic interactions are very common in nature and many traits are influenced by this type of interaction.
