The 9:3:3:1 ratio of the offspring in Gregor Mendel’s dihybrid crosses led him to conclude that _____________________________. 1)some of the alleles were more abundant in the population of garden peas than others 2)the inheritance of different traits are connected to each other 3)some traits are dominant over other traits 4)the inheritance of one trait does not impact the inheritance of another trait
It is 3 . I wish it help. Please comment on my answer. Thank you
Charles Darwin did poorly in school as a young boy. How did his poor performance belie his genius?
Charles Darwin always had a taste for natural history as a kid, as far back as eight, in spite of how he performed in school. When he was a young adult, he got an apprentice ship as a doctor from his father who was also a doctor. This gave him experience with the anatomy of the human body. When being a doctor started to bore him, he learned taxidermy, exposing him to the anatomy of wild animals. Later he joined the Plinian Society which was a student natural history group that often debated and questioned the current topics and views of the subject in that time. Not too mention the many natural historians and evolutionists who also inspired him, one of which was his own grandfather,that gave him the support he needed. I guess that even though his normal school curriculum did not interest him, his self determination was enough to keep him grounded to his interests, proving that sometimes a great education doesn't always make you a genius. (idk :) Charles Darwin was smart in his own ways.
Viruses are not considered to be living things, but they depend upon living cells for energy, reproduction, and protection at the expense of the cells that they invade.The type of relationship described could best be classified as one of A) commensalism. B) mutualism. C) parasitism. D) resignation.
I think C parasitism, I know one thing for sure it's not mutualism because virusses "kill" the cells and with mutualism they "help" eachother.
In eukaryotes, electron transport occurs in theA. inner mitochondrial membrane. B. nucleus. C. cell membrane. D. cytoplasm.
In eukaryotes, the electron transport occurs in the inner mitochondrial membrane.
The correct option is A; inner mitochondrial membrane.
What is the electron transport chain?
An electron transport chain is a collection of protein complexes and other molecules that associate protons across a membrane with the transfer of electrons from electron donors to electron acceptors via redox processes.
The inner mitochondrial membrane of eukaryotic organisms houses the electron transport chain and the location of oxidative phosphorylation.
Does this farmer notice a difference between corn that has been modified through Selective Breeding (Artificial Selection) and Genetically Modified, in terms of water use?
The right answer for the question that is being asked and shown above is that: "Yes,the farmer notice a difference between corn that has been modified through Selective Breeding (Artificial Selection) and Genetically Modified, in terms of water use."
Which step in the scientific method requires you to use your senses to obtain information
The correct answer is observation. Making observation (which is a step in the scientific method) requires you to use your senses to obtain information. In observation, a scientist must be very keen and curious to use all the sense to get all the information needed.
Observation is the step in the scientific method that requires you to use your senses to obtain information.
In the scientific method, the step that requires you to use your senses to obtain information is called observation. It involves gathering data through your senses, such as seeing, hearing, smelling, tasting, and touching. Observation is important in order to gather accurate and objective information that can be used to form hypotheses and conduct experiments.
Which of these characteristics is common only at the embryonic stage of fish and humans, and is suggestive of a common ancestor between the two? A) presence of lungs B) presence of a tail C) presence of gill slits Eliminate D) presence of a vertebral column
The answer is; C
Most often some ancestral characters are preserved in an organism's development hence can be used to study evolutionary relationships. One of these features is the gill slits in embryos. These have been used to postulate that all land organisms, that exhibit gill slits in their embryonic development, emanated from a common fish ancestor. In humans, these gill slits later develop in the pharyngeal.
