why is endosymbiotic theory not a law in science?

Answers

Answer:

Many scientists were skeptical of the endosymbiotic hypothesis because it didn't seem to fit into the theory of evolution as it was understood then. Between 1900 and 1950, biologists made many key discoveries in the field of genetics by focusing on small, random changes in DNA — mutations — that occur when a cell reproduces.

Mendel wanted to find out if the pattern of inheritance for one trait affected the pattern of inheritance for another. What experamint did he perform to test this idea

Answers

Answer: He performed dihybrid crosses

Explanation:

Dihybrid cross is simply refered to as a cross that is done for two genes that are different with regards to their traits. For example, if we cross two maize plants which have different shapes and color let's say that one is white and round while the other maize's colour is yellow and its shape is wrinkly.

Since Mendel wanted to find out if the pattern of inheritance for one trait affected the pattern of inheritance for another, the experiment performed will be dihybrid crosses.

Can you write an essay about what makes a good rapper.
I will mark you Brainly.

Answers

Answer:

There are many rappers out there in the world yet only a few of them are really well known and recognized. Of course this is because they meet peoples expectations. Different people have different opinions on what makes a good rapper. Things that I think make a good rapper is that they need to have good flow, meaningful lyrics that actually make sense and not just rhyme any word with another that doesn't make sense. Another thing is how they are like as a person as well. If they are a pretty decent human being and meets peoples expectations then they will be considered as a good rapper. If the person is not only ignorant but also can't rap well then they are considered bad. Like I said many people have different opinions but these are just mines.

Explanation:

I hope this helps!

A compound that is formed as a common product of the process of photosynthesis is sugar (glucose).

Photosynthesis may be defined as a process through which plants utilize carbon dioxide and convert it into glucose in the presence of sunlight.

The reactants of photosynthesis are carbon dioxide and water, while the products are glucose and oxygen.

The reaction of photosynthesis is given below:

[tex]6CO_2 + 12H_2O[/tex] → [tex]C_6H_1_2O_6 + 6O_2 + 6H_2O[/tex]

Therefore, a compound that is formed as a common product of the process of photosynthesis is sugar (glucose).

why is there is no point in adding more generations when an allele has become fixed

Answers

Answer:

Low genetic diversity, which is seen with allele fixation, is dangerous as it can lead to mass extinctions. If there is little genetic variability within a population and the genetically similar individuals all are susceptible to a certain pathogen, the population will likely cease to exist. This is why we see examples of populations with fixed alleles becoming threatened or endangered
