The <em>Hydra </em>offspring will also have 30 chromosome.
Explanation:
- Budding is a method of asexual reproduction.
- Asexual reproduction takes place through mitosis where diploid cells divide to give rise to identical cells with same chromosome number.
- Hydra reproduces through budding thus, if the parent hydra has 30 chromosome then the offspring will also have 30 chromosome.
Answer;
Mendel's work was not well known until many years after Darwin published his theory of evolution
Explanation;
-Mendel's work was ignored because it was not widely distributed, and he didn't make an effort to promote himself. In actual fact, the reasons are more complex.
-Gregor Mendel had the answer to Darwin's problem. Traits were not blended, but inherited whole. And according to Mendel's laws of inheritance, a trait that might disappear in one generation might reappear in the following generation. Modern Neo-Darwinism combines both Darwin's and Mendel's work.
Answer:
Cyanobacteria
Explanation:
Cyanobacteria were the first photosynthetic autotrophs that used water molecules as the source of electrons. Cyanobacteria were the first autotrophs that performed oxygenic photosynthesis and carried out the splitting of water.
The process of splitting water released oxygen as a gas (O2) which was released in the atmosphere of the earth as a by-product. This led to the accumulation of oxygen in the atmosphere. Some cyanobacteria can fix nitrogen and have specialized cells called heterocyst which serve as the site for nitrogen fixation.
