Answer:
Characteristics outlined below
Explanation:
Anthropods, though they generally possess exoskeleton, segmented bodies and joint appendages, are divided into four (4) groups:
- <em>Tracheata</em> (breath through channels in their bodies. E.g. insects)
- Chelicerata (More than four legs, one pir of chelicerae i.e. claw or pincer. E.g. Scorpions and spiders)
- <em>Crustaceans</em> (Have a large rigid exoskeletal, without a circulatory system. E.g. Shrimps, crabs)
- <em>Trilobite</em> (extinct three-headed/lobed marine species)
Answer:
Third figure shows the best relationship.
(c) is correct option.
Explanation:
Given that,
The diagram best represents the relationship masses of subatomic particles.
We know that,
The mass of proton and neutron are same.
The mass of electron is less than mass of the proton and neutron.
We need to find the best represents the relationship masses of subatomic particles
According to figure,
Third figure shows the best represents the relationship masses of subatomic particles.
Hence, Third figure shows the best relationship.
(c) is correct option.
Answer:
Climate change that is caused by humans
Answer:
To calculate the Carbon Dioxide - CO 2 - emission from a fuel, the carbon content of the fuel must be multiplied with the ratio of molecular weight of CO 2 (44) to the molecular weight of Carbon (12) -> 44 / 12 = 3.7 Emission of CO 2 from combustion of some common fuels are indicated in the table
Explanation:
Answer:
10. Embryology is the branch of biology and medicine concerned with the study of embryos and their development.
11. I think the answer is, Both humans and whale embryos have a tail and a backbone (I'm not sure).
12. Basilosaurid, any member of the family Basilosauridae, an early group of whales that lived from the middle Eocene to the late Oligocene Epoch (about 41 million to 23 million years ago).
13. Protocetids had long snouts, large eyes, and their nasal opening was farther caudally than in earlier archaeocetes.
14. Two ways we know that Maiacetus was a whale re:
1) Their skeletons have all been found among fossils of sea-creatures which suggests they lived in the sea.
2) Their hip bones were strong enough to walk on land, but their short legs combined with long flat fingers and toes suggest they would have had difficulty walking.
15. The name Maiacetus means Mother Whale. Maiacetus is significant because of how well the skeletons were preserved.
Hope this helps! :D
