Answer:
Secondary succession
Explanation:
A secondary succession is when a type of disturbance happens when there is already soil present. In this case, it has already started out with a forest (including plants, trees, and wildlife). Other examples of a secondary succession include a wildfire, hurricane, flood, or human destruction.
This is different from a primary succession. A primary succession occurs when there is no soil present.
What percentage of DNA comes from
each parent during sexual reproduction?
Answer:
50 %
Explanation:
So, each sperm contains 50% of the father's genes and each egg contains 50% of the mother's genes. This makes gametes different from other cells in the body
Answer:
50 from each parent is the correct answer
If a microscope has a 40´ objective lens in place and a 15´ ocular lens, the total magnification of the microscope system under these conditions is
Answer:
600`
Explanation:
The total magnification of a microscope is obtained by multiplying the magnifying power of the ocular lens and that of the objective lens.
Mathematically.
Total magnification = ocular magnification x objective magnification
In this case, ocular magnification = 40`, objective magnification = 15`
Total magnification of the microscope system = 40 x 15
= 600`
Hence, the microscope system under these conditions would be 600`.
1. Match each term with the correct definition. a. External bleeding b. Direct pressure c. Pressure bandage d. Internal bleeding e. Arteries f. Veins g. Tourniquet ____ Using your gloved hand to apply pressure on the wound to control bleeding ____ Bleeding that can be seen coming from a wound ____ The escape of blood from an artery, vein or capillary inside the body ____ A tight band placed around an arm or leg to constrict blood vessels in order to stop blood flow to a wound ____ Blood vessels that carry blood from all parts of the body to the heart ____ Vessels that transport blood to the capillaries for distribution to the cells ____ A bandage applied snugly to maintain pressure on the wound to control bleeding
Answer:
Using your gloved hand to apply pressure on the wound to control bleeding. b. Direct pressureBleeding that can be seen coming from a wound. a. External bleeding The escape of blood from an artery, vein, or capillary inside the body. d. Internal bleeding A tight band placed around an arm or leg to constrict blood vessels in order to stop blood flow to a wound. g. TourniquetBlood vessels that carry blood from all parts of the body to the heart. f. Veins Vessels that transport blood to the capillaries for distribution to the cells. e. ArteriesA bandage applied snugly to maintain pressure on the wound to control bleeding. c. Pressure bandageExplanation:
Direct pressure is a technique used to stop the bleeding on the wound. The person should place both hands over the wound and press firmly till doctors arrive. With this first aid technique, we prevent excessive blood loss, which can cause worse problems in the future.
There are two types of bleeding, external and internal. In the first one, the skin opens, and blood comes out to the exterior. In the second one, the skin is not open, so the blood does not come out to the exterior, but blood goes to tissues around the broken vessel due to an internal injury.
A tourniquet is a first-aid technique use to stop blood flow and prevent that the injured person bleeds out till death. A band, a piece of shirt, or a belt should go around the limb and tie it hard to stop the blood flow and allow the patient to arrive at the hospital. It is a technique usually use when there is a wound that affects the main vessels.
There are different types of vessels. They change in size and structure. Veins are the vessels that carry blood back to the heart, where it will go to the pulmonary circuit to be oxygenated. Arteries will take the oxygenated blood from the heart to the rest of the body. The arteries branch into small vessels called arterioles, and the arteries branch into capillaries which will give oxygen to the cells.
A pressure bandage controls bleeding and prevents the injury from being contaminated. The pressure bandage does not restrict blood flow as a tourniquet.

Horses and donkeys can breed and produce sterile offspring known as mules. Horses and donkeys remain separate species because of this hybrid sterility, which is a(n) Group of answer choices post-zygotic barrier to reproduction. sympatric barrier to reproduction. pre-zygotic barrier to reproduction. allopatric barrier to reproduction. good thing.
Answer:
The correct answer is ''post-zygotic barrier to reproduction''
Explanation:
Biological barriers prevent the exchange of genes between two or more populations, a postzygotic reproductive barrier reduces the survival or reproduction of hybrid offspring. In hybrid non-viability there is low survival of the hybrid, especially during embryonic stages. On the other hand, the sterility of the hybrid occurs when the fertilized egg develops into a healthy but sterile adult. Segregation of aneuploid gametes during meiosis, different gene associations occur on the chromosomes of the parents.
Describe the difference in how energy is transferred to producers and consumers
Answer:
Producers create their own energy using photosyntehsis. They absorb light and water to make glucose. Consumers have to eat, they can't make their own energy.

What happens when two haploid
gametes are combined during
fertilization?
A. The cell doubles in size.
B. The diploid number is restored to the zygote.
C. The cell immediately fuses to any cell any the
vicinity
Answer:
Option B is the correct one
Explanation:
Fertilization between the haploid gametes forms a diploid zygote. ... Haploid (1n) spores germinate and undergo mitosis to produce a multicellular gametophyte (1n). Specialized cells of the gametophyte undergo mitosis to produce sperm and egg cells (1n), which combine in fertilization to make a zygote (2n)

Which of the following conclusions is most likely true if a region experiences unusually low daily temperatures for the season?
the seasonal total of GDD units will be lower than average
the accumulated GDD units still needed to ripen a crop will fall
the average daily value of the GDD will rise
the Tbase value for a particular crop will rise
Answer: D
Explanation: Because if it is going to be cold out every day, the plants aren't gonna grow. So that means the crop rarity will go up, and people would take advantage, and sell them for more of a value.

What happens to waste before it is passed out of the body???
Answer:
It goes through a series of "Events" I'll talk you through them lol.
Explanation:
See, when you eat something it goes down the esophagus and into the stomach, then to your small and large intestine. While it slowly travels through your intestines, your body is slowly taking the nutrients from that piece of food, which makes the food turn into a different color, since all the nutrients is taken out of the food, then the body no longer needs that food. Then it disposes from the body!
Hope this helped!

Explanation: What if I dont want to imagine XD
Answer:
Muscle mass isn'y always a genetic trait, for instence I could work out a bounch and become ripped. if I have kids they could still be couch potatos. That is because traits aquired in ones own life are not passed on, it is the mutations you posses from birth that are passed on if the envirorment aproves of them. If you have lots of muscles and are strong you are not nessisarly more likely to survive anyway, because how are you gonna run away from a lion when youve got all these arm muscles waying you down.

c) Taxol is a cancer medication that makes the structures in the cytoskeleton
more stable. This makes it harder for cells to form mitotic spindles. Why would
this be effective when fighting a tumor? (1 point)
Answer:
Explanation:
Taxol will be effective because it stops the uncontrollable cell division of cancerous cells. It makes it very difficult for cells form mitotic spindles and hence will make it very hard for the DNA to be divided. This will then stop division and causes it to die.
