Hope This Helps!! Have a GREATTT Day!!!How does the genetic code show a shared history among all organisms?
Answer:
All living organisms store genetic information using the same molecules — DNA and RNA. Written in the genetic code of these molecules is compelling evidence of the shared ancestry of all living things. ... Some mammalian genes have also been adopted by viruses and later passed onto other mammalian hosts.
Explanation:
A codon for certain amino acid is the same in every organism.

The fossil record of insects has more gaps and larger gaps than the fossil record of vertebrates. From the following list, choose all the reasons why this is so:
A. Insects were smaller than vertebrates.
B. Insect habitats were not in places where fossils formed.
C. Insects had fewer large, hard body parts that could fossilize the way vertebrates did.
D. Insects left less trace evidence that could fossilize than did vertebrates.
E. There were fewer insects than vertebrates throughout geological history.
Insects left less trace evidence that could fossilize than did vertebrates is the correct reason.
What is Fossil record?A group of fossils that have been examined, classified, and organized both historically and taxonomically make up a fossil record. When organisms die, they are encased in mud and rock and eventually replaced over time by minerals.
These fossils are categorized and organized using a variety of disciplines and specialties, such as comparative anatomy, radiometric dating, and DNA analysis.
Scientists attempt to reconstruct phylogenies, or trees describing the relationships between species, both living and extinct, using information from the fossil record.
Therefore, Insects left less trace evidence that could fossilize than did vertebrates is the correct reason.

When researching and developing new flu vaccines, what region of the world do scientists often look to? Why?
Answer:
Asia
Explanation:
The flu usually starts in Asia. (Sorry i don't know what else to add as an explanation)
Vaccines are given to prevent spread of infectious disease, when researching and developing new flu vaccines, scientists are likely to focus on Europe because that is where flu originated from in the early 90's.
What is a vaccine?A vaccine is prepared to provide active acquired immunity against a particular infectious disease. It could be a virus or bacterial disease.
Influenza vaccines are prepared and given to protect against infection by influenza viruses.
This vaccine production will focus more on Europe because that is where it originated and there are possibilities of new strains developing and more prevalent as such, there is a need for more attention to be focused there.Therefore, when researching and developing new flu vaccines, scientists are likely to focus on Europe because that is where flu originated from.

How would the process of photosynthesis be affected if an outdoor garden didn't receive enough water due to drought
Without sufficient water, biological functions like photosynthesis are drastically diminished. Reduced photosynthesis inhibits plant growth, including root development.
What is photosynthesis?To make food, a process called photosynthesis must be carried out, which can only take place in plants that have the chlorophyll pigment. Sunlight, water, and oxygen are necessary components, and the reaction that takes place is a combination of two distinct processes, one of which is light-dependent and the other of which is light-independent.
The process of photosynthesis is carried out by chloroplasts during the hours of daylight. NADPH and ATP, the two primary results of photosynthesis, are utilized by photosynthetic cells in the process of producing a wide variety of organic compounds.

From the original number of 10 gorillas, there are now 9 gorillas in this population. The correct option is B. After 4 females emigrated, 2 immigrated, 2 gorillas were borned, and 1 male died, there are 9 gorilas.
Available data:10 gorillas in the original group4 females emigrate2 females immigrate2 gorillas are born1 gorilla dies.
So, from the original group, 4 individuals left, so
10 - 4 = 6 individuals
To the group of 6 gorillas, 2 individuals were added, so
6 + 2 = 8
In the group of 8 gorillas, 2 babies are borned,
8 + 2 = 10
And one individual died,
10 - 1 = 9.
The remaining number of individuals in this population is 9. Option B
