Read the passage. Then explain the ways humans have influenced the traits in corn plants and the impacts each biotechnology has had
Many of the types of corn found in grocery stores were originally bred for their taste and productivity. But these varieties are often threatened by pests. This makes it harder for farmers to produce enough corn.
Scientists have used genetic engineering to make GMO corn plants that are resistant to pests. In one type of GMO plant, they added genes from bacteria that live in soil. The genes let the GMO plants produce a bacterial protein that kills certain insects.
Answer:
they have influenced it through genetic engineering
Explanation:
Answer:
The scientists used genetic engineering to manipulate the genes of the corn plant so that they are resistant to pests. A negative impact this biotechnology has is that the genes that help the corn plant resist pests also creates bacteria that kills certain insects.

14. Karim brings a chair from the backyard into his house and is going to stack it on top of another chair. Both chairs are the same size and have the same number of molecules. The diagram above shows the chairs before they touch. Use the information in the diagram to answer the question.
How does the temperature of the bottom chair compare with the temperature of the top chair before the chairs touch? What will happen after the chairs have been touching for a while?
a Before the chairs touch, the bottom chair is cooler than the top chair. Once the chairs are touching, the top chair will transfer kinetic energy to the molecules in the cooler bottom chair until both chairs reach the same temperature, which will be in between their starting temperatures.
b Before the chairs touch, the bottom chair is hotter than the top chair. Once the chairs are touching, the bottom chair will transfer kinetic energy to the molecules in the cooler top chair until both chairs reach the same temperature, which will be in between their starting temperatures.
c Before the chairs touch, the chairs are different temperatures. Once the chairs are touching, both kinetic energy and cold energy will transfer between the molecules in the two chairs until both chairs reach the same temperature, which will be in between their starting temperatures.
d Before the chairs touch, the bottom chair is hotter than the top chair. Once the chairs are touching, the cooler top chair will gain kinetic energy until the molecules in both chairs have an energy of 35, because hotter things increase the temperature of cooler things.

Answer:
Living things are highly organized and structured, following a hierarchy that can be examined on a scale from small to large. The atom is the smallest and most fundamental unit of matter.
Explanation:
Why do vestigial structures not always disappear and still show up in organism? For example humans still have a tail bone, even though we don't have a tail.
1) The organism depends on them to survive
2) The structure is not harmful to the organisms survival
3)Sticks around just incase we need it again
4)The structure makes the organism look cooler
Answer:
3 would be my best guess
Explanation:
we dont depend on it
its not harmful but that wouldn't be a reason to have it
it doesnt look cool

Will give brainliest please help :(
Answer:
The Monera Kingdom consists of all bacteria. Bacteria are one-celled organisms that are made of very simple components. They often lack a nucleus and a cell membrane. Bacteria are universal in that they can be found everywhere. They are even some living in the air you breathe. There are some harmful bacteria that can cause illness and disease and there are others that are essential for us to survive. Bacteria help to break down dead matter and also food in our digestive system.
Most organisms in the Monera Kingdom are able to reproduce through a process called fission. This means that a single cell copies its DNA and then divides into two identical cells. Because each cell comes from a previous cell, there is not much diversity among certain monera types. Some moneran bacteria replicate every 20 to 40 minutes.
The bacteria of the Monera Kingdom have some very unique and interesting characteristics. They can exist almost anywhere and are very tolerant of both extremely high and low temperatures. Some monera have the ability to move using their flagella but others cannot move on their own.
There are a few monera that can make their own food but bacteria cannot. Bacteria feed on dead and decaying matter. Blue-green bacteria or blue-green algae are a special type of moneran bacteria that can produce its own food through photosynthesis. This is because blue-green bacteria contain chlorophyll.

How did the concept of biodiversity originally gain traction in the scientific community?
Answer:
Explanation:Raymond Dasmann was the first person who used the term Biological diversity in 1968. He was a wildlife scientist and conservationist. But this term gain attraction in the scientific community in the 1980s.
So during 1980s the scientific community and activists were concerned about the extinction of biodiversity so this topic gain attraction as a research subject among the scientific community.
The issue of biodiversity was first published in 1987 in journal Conservation Biology which soon popularized the concept of biodiversity and became the main journal for publication of scientific research on biodiversity.
Therefore through publication, the term biodiversity appeared which gain attraction in the scientific community, society and in politics.

Declining genetic diversity is a result of both human activities and natural disasters. Classify the images as natural disasters or human activities.
Answer:
Natural Disaster: A and D
Human Activity: B and C
Explanation: This is what it looked like to me. The volcano and the cracking were caused by the Earth. And the Car and the cutting down of trees was caused by Humans.
Answer:
A & D in Natural Disaster. B & C in Human Activity.
Explanation:
Volcanos were not build by mankind nor do we control the blast. The sand cracking is not because of Mankind. Cars were built by mankind and the smoking of it is because of us. Trees don't cut themselves mankind does.

Explanation:
which population is most likely to survive? (PLEASE ANSWER ASAP AND CORRECTLY, I WILL AWARD BRAINLIEST) (image below)
Populations 1 and 2 will most likely survive.
Populations 2 and 3 will most likely survive.
Only Population 2 will survive because it is the only population with variation.
All the populations will survive because the seals will change the thickness of their blubber if they need to.
Answer:
populations 1 and 2 will most likely survive.
Explanation:
so here's my thinking- seeing as how population 1 only has seals with thin blubber they will automatically survive because they won't need to adapt to the environment. but population 2 has both thin and thick blubbered seals and seeing as how the thick blubbered ones will most likely just die out the thin blubbered ones will 'take over'
good luck :)
i hope this helps
have a nice day !!
Answer:
Populations 1 and 2 will most likely survive.
Explanation:
If the water is changing to warm, the seals with no blubber wont get too hot. The thick seals will overheat.
