Hi, there it's U-G-G
Hope this helps and correct :)
Explanation:
Secondary or second-level consumers eat primary consumers. Tertiary or third-level consumers eat lower-level consumers and are sometimes called final consumers. Some secondary and tertiary consumers eat plants as well as lower level consumers, making them omnivores.
It’s an illusion to make you think the caterpillar is green but it actually is every other color but green
In the scenario give above, the disease reservoir is the PARROT and the possible transmission method is INDIRECT CONTACT THROUGH AIR.
Disease reservoir refers to a source of a particular pathogen in an environment. A disease reservoir can be a person, an animal or an inanimate object like soil. In the case given above, the parrot is the disease reservoir and it passes the disease pathogen to the student. Pathogens are transmitted through four distinct ways, these are: direct contact, indirectly through the air, indirectly through contaminated object and through vectors. The disease pathogen was possibly passed to the student when the parrot was talking via tiny mucus droplets that escape from the bird's mouth.
Answer:
Option 3, 20 or 22
Explanation:
A newly discovered species of dung beetle has 2n = 16 chromosomes. It mates with a closely related beetle species that has 2n = 12 chromosomes. How many chromosomes would there be in an allotriploid beetle produced from this cross?
- 40 or 44
- 20 or 22
- 20 or 22
- 36 or 48
- 40 or 44
Solution
An allotriploid is a species which contains three sets of chromosomes of different species .Crossing can result in triploid offspring with diploid gamete of one species and regular haploid gamete of other offspring
Case I - Resulting offspring (3n) = Gamete I (2n) + Gamete II (n)
OR
Case II - Resulting offspring (3n) = Gamete II (2n) + Gamete I (n)
Case I

Case II

Hence, option 3 is correct
