What do you think would happen if cells were not able to replicate and divide
Answer:
theyed eventually become extinct because they are unable to reproduce
Answer:
Each cell has an identical set of DNA (chromosomes), and this DNA is also identical to that of the parent cell. If the cell cycle is not carefully controlled, it can cause a disease called cancer, which causes cell division to happen too fast.

Can you describe a frogs metamorphosis, including whether it is complete or incomplete
Explanation:
Frog undergoes a complete metamorphosis. It includes the egg, tadpole, froglet and then adult frog stages. In complete metamorphosis the hatchling does not resemble the parent and changes as it grows to be an adult.
During metamorphosis the tadpole will develop back legs first, then front legs. Around 6 weeks of life the mouth starts to widen. Sometime around 10 weeks the froglet’s, as it is now called, eyes start to bulge out and the tail begins to shrink and eventually disappear. When the lungs finish developing the froglet makes it’s way onto the land and, Ta-da! It’s a frog!

When the environment changes, organisms need to ______ or ____ to survive.
Answer:
adapt & evolve
Explanation:
When the environment changes, organisms need to adapt or evolve to survive.
How organisms adapt and survive to the changing environment?Natural selection is the process that results in this. Natural selection causes a species' nature to progressively change so that it can fit into the niche. A species can persist for a very long time before going extinct.
Environmental changes affect whether species are able to reproduce and survive, and this can result in population-level evolution. descent while being modified.
The process by which organisms adapt to their environment in order to increase their chances of surviving in that environment is known as evolutionary adaptation, or simply adaptation.

how is it possible for one twin to get skin cancer but the other one doesn´t
Looking at most newborn twins squirm contentedly in their cribs, you'd never guess that some were recently in peril. That's because carrying multiples raises the risks that a woman can suffer complications before she actually delivers.
Many twins are miscarried early in the pregnancy, often before a woman even knows she's pregnant. As reported in the International Journal of Fertility, only about one in eight embryos that starts as a twin is born as a twin. If they do survive, twins are usually born healthy. However, they are still more likely than other babies to have birth defects or to be born prematurely or underweight.
Carrying twins can be hard on you, too. You'll be more likely to develop pregnancy-related high blood pressure or diabetes. And there's a greater likelihood you will have a cesarean section when you deliver.
If you're carrying twins, some simple lifestyle changes and good prenatal care may help you reduce the likelihood of the following complications.
Low birth weight
Because they have to share nutrients and living space, newborn twins tend to be smaller than single babies. Even full-term twins often weigh less than 5-1/2 pounds each, making them vulnerable to a variety of health problems. You can help your babies reach a healthy size by making sure you put on enough weight during pregnancy. Try to eat 300 calories more each day than you would if you had a single baby (about 2,700 calories in total). If you had a healthy weight before pregnancy, you should aim to put on about 35 or 45 pounds.
Unequal size
Twins don't always share equally. In roughly 30 percent all twin births, one baby will be larger than the other. Some studies suggest that if one of your babies is at least 25 percent heavier than the other, one or both of them may be more likely to have breathing problems or need intensive care. Your doctor will track the growth of both your babies throughout your pregnancy. The first signs of unequal growth usually appear in the third trimester.
Twin transfusion syndrome
Twin transfusion syndrome poses a dangerous threat to identical twins who share a single placenta. It's normal for such twins to exchange blood during a pregnancy. But in about 20 percent of cases, one twin starts pumping large amounts of blood to the other twin, putting both of them at risk. In severe cases, the twin receiving the extra blood may develop heart failure while the other twin becomes dangerously anemic. Early diagnosis and treatment can slow the abnormal blood flow and lower the risk of complications.
Birth defects
Birth defects are common in twins, especially identical twins. Taking folic acid before and during pregnancy can help prevent neural tube defects. As reported in the medical journal The Lancet, however, about 10 percent of all identical twins are born with a birth defect such as a heart problem, a shortened limb, a club foot, or a dislocated hip (the conditions listed are linked to having less space in the uterus and would not be affected by folic acid.) Most of these conditions are treatable, however.
Risks to the mother
Your doctor will check you regularly throughout the pregnancy for signs of high blood pressure or diabetes. When detected early, both of these conditions can be controlled before they have a chance to threaten your pregnancy.
Special care
Carrying twins means you'll probably get extra attention from your doctor throughout your pregnancy. The doctor may suggest cutting back on activities between the 20th and 30th week of pregnancy, even if you haven't had any signs of labor. Many physicians also recommend an extra monitoring check on the babies' heart rate and movement, such as an ultrasound or nonstress test. A biophysical profile, which checks on heart rate, movement, and the amount of amniotic fluid in your body, might also be indicated. If you do go into labor prematurely, your doctor may suggest drugs to stop the labor or use corticosteroids to speed up the development of the babies' lungs.
It's possible that you may be able to deliver twins vaginally. But if the labor is difficult, the birth canal is too narrow, or one or both of the infants is in the breech position, you may have to undergo a c-section, in which the babies are delivered through an incision in your uterus. Talk to your doctor about what you can do to prepare for delivery.
Twins are a special challenge, both before birth and after. For now, your job is to stay healthy and get top-quality prenatal care. Two important people are counting on you.

Do plants need to eat?Or do they acquire energy through a method different from animals?Write down the differences on how a tree and an ostrich acquire the energy they need for survival.
Plants acquire energy through a method known as photosynthesis which is different from animals. Plants make their food from the process called photosynthesis as they are autotrophs while animals depend on their food on plants and they are called herbivores.
What are Autotrophs?
Autotrophs are the organism that can produce its own food using light, water and carbon dioxide or some other chemicals. They are also known as primary producers.
The most familiar type of autotrophs are plant but apart from plants many different types of autotrophic organisms are there. For example, algae which live in water, phytoplankton which live in ocean and some type of bacteria.
Mostly autotrophs used the process called photosynthesis to make their own food. In this process, Autotrophs used energy from the Sun to convert water obtained from the soil and carbon dioxide obtained from the air to produce a carbohydrate called Glucose . It give energy to the plant.
Some rare autotrophs produces food through a process called Chemosynthesis . In this process, they make their own food using energy from chemical reaction combining Hydrogen Sulphide or Methane with oxygen . Organism that uses Chemosynthesis for making their food lives in extreme environment . For example, Bacteria live in active volcanoes oxidize sulphur to produce their own food.
Thus, plants acquire energy through a method known as photosynthesis which is different from animals. Plants make their food from the process called photosynthesis as they are autotrophs while animals depend on their food on plants and they are called herbivores.
