Answer:
Transposition to different chromosomes by the ancestral gene
Explanation:
Transposable Elements (TEs), also known as jumping genes, are genetic mobile elements which are able to move from one location to another on the genome. There are two major mechanisms of TE transposition: 1-cut-and-paste mechanism, where one particular TE is inserted into a new position on the genome without replication, and 2-copy-and-paste mechanism, where a new copy is generated and the original TE remains at the original genomic site. In this case, it is likely that new TE copies containing the ancestral (duplicated) gene have proliferated through the copy-and-paste mechanism.
write a 5-7 sentence paragraph explaining what happens to co2 levels in the world over the course of the year. add as much context and details as you can
Answer:
The amount of CO2 found in the atmosphere varies over the course of a year. Much of this variation happens because of the role of plants in the carbon cycle. Respiration happens all the time, but dominates during the colder months of the year, resulting in higher CO2 levels in the atmosphere during those months.
Explanation:

Examine the model of the carbon cycle select all of the processes that we turn carbon compounds to the atmosphere.
The processes that considerably turn carbon compounds into the atmosphere are the decaying of organisms, the respiration of animals, and emissions from automobiles and factories. Thus, the correct options for this question are B, C, and E.
What do you mean by the Carbon cycle?The carbon cycle may be defined as a type of biogeochemical cycle through which carbo and its derivative products are exchanged among the various spheres of the earth's surface. Carbon is considered one of the main components of biological systems.
In the carbon cycle, rhe process of photosynthesis utilizes the carbon from the atmosphere in order to produce chemical energy in the form of glucose. While the excretion of animal waste products is responsible for nitrogenous compounds like urea or ammonia.
Except for these two, all other options are directly liberating carbon into the atmosphere which can easily be demonstrated in the carbon cycle.
Therefore, the correct options for this question are B, C, and E.

state three reasons for preventing food spoilage
Answer:
1) Refrigerate or freeze
If you freeze or refrigerate the food, the bacteria or whatever organism growth will slow down in the food by a Greta amount due to the coldness. Refrigerate might be a temporary food soteage for like a week or 2/ month max. While freezing will just freeeze the bacteria and mold on the food which can be stored up to 3- 12+ months even. But then again it will be most likely flavorless by the end or have no nutrients value. You can stores mik in the freezer for a while but its not recommended to taste, same for other thing syou usually see in the fridge, eggs/ vegetables/fruits/ milks/ yogurts/ etc.
2) No moisture, no water of any kind (drying in the sun or salted)
So every living thing we know of needs water. Including bacteria and mold. Without water, theres no place to thrive. No place to thrive means no bacteria and food is safe for a good amount of time. Dried foods can last a really long time, sure some types are really unpleasant but its edible. But you can’t techincally “dry” meat since it will be A whole nest for flies before it even reaches the halfway mark. You can slat it which will lessen he time but still really efficient. Salt absorbs water and breaks down any type of Stuff. Its like a mini acid.
3) Canned good and no air access (Pressurized/ controlled container)
This is done by putting all your favortie food in a metal container. With no air access, the bacteria or mold in the food already in can’t escape and new ones can’t get in. THe can then is boiled to a certain tempature where then the bacteria dies. Now the food can even be perishable stuff like meat (most common fishes), fruits and even a nice can of liquid soup. Nothin g can get in. Nothing can get out but nothing CAN get out becuase eveythign is dead. Canned food can last REALLY LONG, good for long term expeditions without a fire or food.
Answer:
Drying is one of the most ancient food preservation techniques, which reduces water activity sufficiently to prevent bacterial growth. Refrigeration preserves food by slowing down the growth and reproduction of microorganisms and the action of enzymes which cause food to rot

Choose the correct connective tissue.
1)Bone to bone
2)Muscle to muscle
-ligament
-tendon
Explanation:
A tendon is a fibrous connective tissue which attaches muscle to bone. Tendons may also attach muscles to structures such as the eyeball. A tendon serves to move the bone or structure. A ligament is a fibrous connective tissue which attaches bone to bone, and usually serves to hold structures together and keep them stable.
A tendon is a fibrous connective tissue which attaches muscle to bone.
A ligament is a fibrous connective tissue which attaches bone to bone.
What is tendons and its function?
A tendon is a cord of strong, flexible tissue, similar to a rope. Tendons connect your muscles to your bones. Tendons let us move our limbs. They also help prevent muscle injury by absorbing some of the impact your muscles take when you run, jump or do other movements.
What is ligament and its function?
Ligaments often connect two bones together, particularly in the joints: Like strong, firmly attached straps or ropes, they stabilize the joint or hold the ends of two bones together. This ensures that the bones in the joint don't twist too much or move too far apart and become dislocated.

Most nerves of one of the sense organs go to the spinal cord before they go to the brain. Which organ is
this? (Think of your own body.)
Answer:
Umm every sense of organs travels in the spinal cord.
Most nerves of one of the sense organs go to the spinal cord before they go to the brain, and that organ is the one that is involved in the reflex action because it happens in a very short time and is controlled by the spinal cord before the brain..
What is the significance of the reflex action?Reflex actions are important because they allow the body to respond quickly to stimuli without waiting for the brain, and they can be especially important in situations where a quick response is necessary to avoid danger, such as when the hand touches hot substances and the hand suddenly goes back, which is due to the motor neuron action of the spinal cord.
Hence, most nerves of one of the sense organs go to the spinal cord before they go to the brain, and that organ is the one that is involved in the reflex action because it happens in a very short time and is controlled by the spinal cord before the brain.

When a stream's velocity decreases from 300 to 200 centimeters per second, which size sediment will be deposited?
Middle size sediment will be deposited on the ground when the speed of flowing water decreases.
Deposition of sedimentsWhen a stream's velocity decreases from 300 to 200 centimeters per second, the middle size sediment will be deposited because of the lowering velocity of the stream. Big size sediments hardly move by the water of the stream.
While on the other hand, middle and small sized sediments easily moved by the flowing water due to their light weight so we can conclude that middle size sediment will be deposited on the ground when the speed of flowing water decreases.

11. Question: Imagine 20 babies were born. 10 had blue eyes, and 10 had brown eyes. What traits do their parents probably have?
Answer:
The correct answer is - brown heterozygous Bb and blue eye bb.
Explanation:
In the provided question it is given that there are 20 babies born, 10 babies had blue eyes and 10 had brown eyes. As it is known that brown eyes are dominant over blue eyes, therefore, on the basis of this we can say that all blue-eyed babies have a bb genotype and as brown eyes are dominant traits babies must have at least one copy of the B allele which represents brown eye trait.
case1:
Parent 1 : bb
parent 2: BB
B B
b Bb Bb
b Bb Bb
there are 100% brown eye offspring so this is not the case
case 2:
Parent 1 : bb
parent 2: Bb
B b
b Bb bb
b Bb bb
here, 50% brown eyes and 50% blue eyes offspring produced thus, the parent trait will be brown heterozygous and blue eye.

Chromosomes often exchange segments of DNA during meiosis. How might this increase the survival of a species?
Answer:
Because of recombination and independent assortment in meiosis, each gamete contains a different set of DNA. This produces a unique combination of genes in the resulting zygote. Recombination or crossing over occurs during prophase
