Answer:A. the same number of chromosomes as was contained in the zygote.
Explanation:a zygote is formed when the sperm fertilize the egg .
After fertilization,the zygote undergoes cleavage.cleavage is the mitotic Division of the cells of a zygote to produce daughter cells.
These daughter cells are called blastomere,which contains the same number of chromosomes as the parent cells.the cells formed do not grow in size but continues to divide, forming a mass of cells.
This mass may be solid at first but as cleavage continues,the cells move away from the center,leaving a fluid filled cavity in the middle (blastocoel).
The mass of cells are called blastula.
Sexual selection example; The brightness of the feathers of a peacock. You may also see similar traits in other birds, where some dance and show off bright feathers to attract a mate, where other build nests. These specific traits do not increase their chance of survival, and are not learned. They increase their fitness because they increase their chances of reproduction and passing on their genes.
Survival of the fittest = Survival of those who survive, and reproduce
Answer:
first third one Bb and the last one BbEe
Explanation:
Answer:
1. Observation
2. Question
3. Hypothesis
4. observation
5. prediction or test
Explanation:
1. A question is being asked when something is being enquired about and generally consists of words like who, what, where, why, when etc with a question mark. Hence the below given statement is a question
Where is the whale meat being solid in Japanese markets coming from?
2. Observation is an interpretation made after viewing something for a certain period of time with concentration. Hence below given statement is an observation –
The availability of whale meat in Japanese markets exceds that expected from the reported legal captures of whales
Whales are being harvested illegally and their meat sold in markets in Japan
3. Hypothesis is an “if” and “then” scenario, in which a fact is rejected when there are not enough causes to support it.
If whale-s are being illegally harvested, reported whale captures will be far lower than the number of captures predicted by genetic analyses of whale meat in markets
4. prediction, or test1
When something is being experimented on or with to reach a conclusion. Hence the below given option is a prediction or test
Scientists subject whale meat to genetic analysis to determine its likely capture location and to extimate whale captures at that locationDrag each statement under the step in the scientific method that it demonstrates.
Explanation:
The exocrine component of the pancreas is the pancreatic islets. The endocrine cell of the pancreas produces hormone insulin. The major hormones released by the endocrine gland inside the pancreatic are glucose and glucagon, which control blood glucose levels, and cortisol, which inhibits insulin and glucagon production.
