Answer:
Explanation:Two of the nuclei (the polar nuclei) move to the center of the embryo sac and fuse together, forming a single, diploid central cell. This central cell later fuses with a sperm to form the triploid endosperm, which will ultimately provide nourishment for the developing embryo (analogous to yolk in animal eggs).
Answer:
endosperm
Explanation:
The second fertilization results in the endosperm, which is a special tissue used to nourish the embryo.

Use the student's hypothesis to predict which parachute, A, B or C, will hit the ground first. Give a reason for your answer?
Answer:
The heavier will come first to hit the ground.
Explanation:
That parachute will come faster and hit the ground first which has more weight than other parachutes because the heavier objects comes to the earth at faster rate as compared to light objects. So if all the three parachute has same size and shape but difference in weight than the heavier one comes to the ground first as compared to other two parachutes.

briefly explain how down syndrome results from meiosis
Answer:
In translocation, a piece of chromosome or a whole chromosome breaks off during meiosis and attaches itself to another chromosome. The presence of an extra part of the number 21 chromosome causes the features of Down syndrome.
how are pure carbon, oxygen, & hydrogen different from the compound ethanol which contains all three of those elements
marking brainliest!!
Answer:
They are different because ethanol is a compound that is made by a certain amount of carbon, oxygen and hydrogen, these are the elements that made up ethanol.
Explanation:
Think of it like this ethanol is a cake and carbon, oxygen and hydrogen is the eggs, flours and sugar that is used to make the cake.

The breaking down of starch into its component sugars would be an example of
A. Catabolism
B. Cell Division
C. Protein Synthesis
Answer:
A. Catabolism
Explanation:
Catabolism is the process by which complex molecules are broken down into simpler molecules, like starch to component sugars or proteins to amino acids. Cell division is the process by which a parent cell will divide into two or more daughter cells, like mitosis or meiosis. Protein synthesis is the process by which proteins are made, this is through transcription and translation.

Which approach would be least helpful in determining genetic differences between species?
Answer:
the least helpful would be a straight up guess, the best way would be to to back in the history of that species and study how they lived and survived and reproduced and all that stuff
Explanation:
Comparing physical characteristics between species is not a reliable method for determining genetic differences because many physical traits are influenced by environmental factors and may not necessarily reflect the underlying genetic differences between species.
What is an example of this ?For example, two species may have different fur colors or patterns, but this difference may be due to environmental factors such as exposure to different types of light rather than genetic differences.
In contrast, analyzing DNA sequences can provide a more precise and objective way to identify genetic differences between species. By comparing the DNA sequences of different species, scientists can identify variations in genes and regulatory regions that may be responsible for differences in traits or behaviors between species.
This approach can also reveal the evolutionary relationships between species and provide insights into how genetic variation has driven the diversification of life on Earth.
Therefore, Advances in genomic technologies have made it increasingly feasible to sequence and compare the genomes of diverse species. Comparative genomics has already revealed many insights into the genetic basis of traits such as human disease susceptibility, adaptation to environmental challenges, and the evolution of complex traits such as intelligence and social behavior.

In the oxygen–carbon dioxide cycle,
a. animals produce oxygen used by plants for photosynthesis.
b. animals produce oxygen used by plants for respiration.
c. animals produce carbon dioxide used by plants for photosynthesis.
d. animals produce carbon dioxide used by plants for respiration.
Answer:
C
Explanation:
Animals produce carbon dioxide as a byproduct of cellular respiration. Plants use the carbon dioxide through photosynthesis to produce oxygen.
Animals produce carbon dioxide as a byproduct of cellular respiration. Plants use the carbon dioxide through photosynthesis to produce oxygen, thus, animals produce carbon dioxide used by plants for photosynthesis.
What is the oxygen and carbon dioxide cycle called?Photosynthesis is the method by which plants use sunlight, water, and carbon dioxide to make oxygen and energy in the form of sugar.
Thus, option "C" is correct, animals produce carbon dioxide used by plants for photosynthesis.

The arctic fox is uniquely adapted to its environment with white fur for camouflage, a small nose and ears and warm coat to prevent heat loss and strong paws for running and hunting. Which statement best describes how the arctic fox population may have adapted to its environment over time?
Choose the correct answer.
Foxes were bred to meet human needs for white fur.
Foxes developed smaller ears and noses in response to their cold climate. They were able to survive and pass this trait on to their offspring.
Foxes changed their fur to white to hide from predators and disguise themselves from their prey. They were able to survive and pass this trait on to their offspring.
Variation existed in the traits of the fox population. Foxes with smaller ears and noses were able to stay warmer and were more likely to survive and reproduce to pass their genes on to offspring. Over time, the fox population showed a shift to smaller ears and noses.
Answer:
D
