Answer:
they considered valid but a certain idea of acquired characteristics being inherited was rejected
Explanation:
his theory was that if the environment demanded a need or use of a structure in an organism it developed it in response to demand leading to natural use or disuse of structures which he said that these new structures would be passed to their offspring leading to emergence of a new species. scientists accepted that the environment has a role in directing phenotypic changes in an individual taking a body builder for example since his muscles will become huge due to continuous use of the muscles in exercises
but scientists rejected his theory of these acquired characteristics were inherited since phenotypically acquired characteristics that do not affect the genotype of an individual can't be inherited
Answer:
<em>The correct option would be option 3) organism 1 and 3 will be more closely related than organisms 2 and 4.</em>
Explanation:
Depending on the physical characteristics only, we can see that the organisms shown in number 1 and in number 3 are similar o one another but not purely identical. This means that these organism are closely related to one another.
The organisms shown in option 2 and 4 are not very similar to one another depending on the physical characteristics. Hence, we can say that organisms shown in number 1 and number 3 are more closely related to one another s compared to the organism shown in option 2 and 4.
Blood types:
AB +
AB -
A +
A -
B +
B -
O +
O -
It is possible to have a child with O blood despite the parents having different blood types.
While the man tested for B blood, he could have been a combination between type o and B whereas, the woman was a combination of type A and o. Since A/B are dominant, they would 'stand out' contrarily to o.
This means that their children could have AB or O blood.
Ribosomes, the cytoplasm and cell membrane are all in plant, animal and bacteria cells.
If mitosis occurred without cytokinesis, the cell would contain two nuclei and twice the DNA. If cytokinesis occurred without mitosis , one of the new cells would lack DNA and a nucleus altogether. The cell cycle is regulated by signals both inside and outside of the cell.
