Answer: The correct answer to the question is option D
CAST FOSSILS.
Explanation: To understand what a cast fossil really is,let's look at what a fossil is generally.
Fossils are traces of what are formed and left of living things which dates back to a long time ago. Fossils are often found in sedimentary rocks examples; Shales, limestone and sandstone.Fossils are left over animals/plants.
Not all fossils are remains of living things.
There are different types of fossils; FROZEN FOSSILS; When an animal is trapped and freezed as a result of drop in temperature.
IMPRINT FOSSILS; They are prints made and left when animals walk or move over clays,these imprints dries and get covered by other sediments.plants also leave imprint fossils.
AMBER FOSSILS; These are fossils that are formed when tiny insects and bugs become trapped in saps of trees, when these saps dries up,they become hard and and an Amber is formed.(a seminiferous material).
CAST FOSSILS; These are fossils that form as a result of the death of plant,animal or any organism,when this happens,chemical reaction occurs which brings about a degradation in the bones and flesh if the organism,cavities are formed and minerals are deposited in those cavities bringing about a cast which looks like the original form or image of the organism.
Answer:
The correct answer is b. all tall
Explanation:
If the genotype of one parent for height is Tt and another parent is TT then after the fusion of gamete all the offspring will show tall phenotype because all the offspring will have at least one allele of tall character.
T t
T TT Tt
T TT Tt
So after cross two phenotype would be homozygous dominant for tall character and the other two will be heterozygous dominant for tall character. Therefore all the offspring would be tall.
B is the correct answer because the density it the salts would make the water increase therefore sink faster
Answer:
When a new infertile hybrid appears in an environment, it feels like an anomaly in the environment and there are no possible measures to classify it as a new specie or a member of a specie just by a physical examination. When 5110 subject appears in that environment it is possible to classify it as a piece of a terminated branch of only one member as an anomaly of the closely related species.
His fate is solely relied on better care of himself for a good life span cause there are no other measures to save him. Futhermore added he is also not a proper member of a specie so no mating oppurtunities at all.
Hi,
The answer is letter a.
I hope this helps. If you’d like further explanation please let me know. Also, English is not my first language, so I’m sorry for any mistakes.
