A is the answer according to my notes
Answer:
Gametes from both dogs are needed to maintain the correct number of chromosome in the offspring
Explanation:
Reproduction in dogs is a <u>sexual process</u>. During the process, haploid gametes from both the male and the female (sperm from males and eggs from females) fuse together in a process known as fertilization in order to produce <u>diploid offspring.</u>
The haploid gametes ensure that the offspring produced during fertilization has the correct (diploid) number of offspring. Because the production of gametes involves <u>meiosis and crossing over of genetic materials between chromosomes, offspring produced by sexual reproduction are usually genetically different from one another. </u>The random fusion of gametes further ensures that offspring from the same parents are different from one another.
Membrane is the answer i think
Answer: The main reason for a water polarity is a covalent bond between oxygen and hydrogen atoms that occurs because of an electrostatic attraction between positively and negatively charged regions of mentioned atoms.
Explanation:
Answer:
An invasive species enters the environment.
Explanation:
All other answers already naturally happen in an environment so they are stable. But if an invasive species enters, the ecosystem will be less stable because invasive species dominate ecosystems which isn't natural to the animals that live there. So for example, if someone introduced an invasive species to the ecosystem, it can cause many changes like if it was a predator, there'll be less primary consumers (the animals that eat plants) because the invasive species isn't natural to them.
