What are the 4 steps of mitosis? What occurs during each?
Explanation:
There are four stages of mitosis: prophase, metaphase, anaphase and telophase.1) Prophase: chromatin into chromosomes, the nuclear envelope break down, chromosomes attach to spindle fibres by their centromeres 2) Metaphase: chromosomes line up along the metaphase plate (centre of the cell) 3) Anaphase: sister chromatids are pulled to opposite poles of the cell 4) Telophase: nuclear envelope reforms, chromosomes unfold into chromatin, cytokinesis can begin The order of the stages of mitosis can be remembered using the mnemonic PMAT.
What is natural selection?
- A prodded that selects variations that help with survival and that spreads the variations to more offspring
-A process through which nature select an individual within a population for extinction
-A process that causes all populations to gradually increase in size
-A process that causes random variations to appear in the offspring of every generation
A process that selects for variations in a population that help with survival and that spreads the variations to more offspring.
59:14 Organisms that live in the tundra have developed unique adaptations that aid in their survival. Ursus maritimus has a variety of adaptations which enable it to survive in the tundra. It is the largest terrestrial carnivore, but it is also an excellent swimmer that spends much of its time in and near the water hunting its favorite food. It has large paws with small bumps to provide traction as it walks across the ice. Its fur is helpful as camouflage during the winter months, but not as helpful during the summer. Which organism has the adaptations described that enable it to survive in the tundra
Answer:
Polar bear.
Explanation:
Polar bear is the organism that has the adaptations which enable it to survive in the tundra. the polar bear has white skin and fur on all its body which helps it to camouflage in the ice and to prevent the loss of heat from its body. The polar bear catch its favourite food in the water which is the fish that provide high nutrition to the polar bear. It is a good swimmer and have large paws with small bumps that helps it to provide support while walking on the ice. The scientific name of polar bear is Ursus maritimus whose features are described in the question.
i'm working on a lab report on water erosion on edg lol
pls help i'm so behind
is it okay??
Some facts about Water erosion :
Water erosion is the detachment and removal of soil material by water. The process may be natural or accelerated by human activity. ... Water erosion wears away the earth's surface. Sheet erosion is the more-or-less uniform removal of soil from the surface.
Water and Wind Erosion (cause)
Water erosion is the removal of soil by water and transportation of the eroded materials away from the point of removal. Water action due to rain erodes the soil and causes activities like gully, rill, and stream erosion leading to the downstream effects of flooding and sedimentation.

4. Some cells, such as human nerve and muscle cells, contain many more mitochondria
than do other cells, such as skin cells. Infer why some cells have more mitochondria
than others. (SB1a)
A. The cells divide more frequently.
B. The cells use more energy.
C. The cells store more nutrients.
D. The cells degrade more proteins.
✓ B) The cells use more energy.
Some cells such as human nerve and muscle cells.
Some cells have more mitochondria because the cells use more energy. The correct option is B.
What are mitochondria?Mitochondria are the powerhouse of the cell. It is a long cylindrical organelle. Some cells contain more mitochondria than others because they require more energy. The mitochondria store energy for the function of the cell.
So, for example, the muscle contains a lot of mitochondria, as does the liver, the kidney, and, to some extent, the brain, which runs on the energy that those mitochondria make.
Depending on the function of the cell, several mitochondria are frequently found in one cell. Mitochondria, like other organelles, are found in the cytoplasm of cells.
Therefore, the correct option is B. The cells use more energy.

What is adaptation? What are the two types of adaptation? Give an example each.
Answer:
adapting can be learning from your environment and ways to survive etc.
Adapting can also go to sexual reproduction to survive diseases unlike asexual reproduction.
An adaptation is a trait which increases the relative fitness of an individual. The fitness of an individual has 3 components: 1. Probability of survival to reproductive age. 2. Probability of attracting a mate. 3. Average number of offspring. Any trait which increases the fitness of an individual by positively impacting one of these three aspects is considered an adaptation.
There are 2 types of adaptation: physical and behavioral. These are self-explanatory. Physical adaptations could include things like adaptations to morphology or physiology of an organism. Behavioral adaptations are adaptations to, well . . . behavior :)

The ocean continued to shrink until, about 270 million years ago, the continents that were ances tral to North America and Africa collided. Huge masses of rocks were pushed west ward along the margin of North America and piled up to form the mountains that are now the Appalachians. Well, mountains are limited in their theoretical height by several processes. First is called isostasy the bigger a mountain gets, the more it weighs down its tectonic plate, so it sinks lower. The second is called glacial buzzsaw the taller and colder a peak, the faster snow and ice will wear it down/away.

PLEASE HELP ITS URGENT What is the functionof the peripheral nervous system? A. To transmit signals between the body and the brain or spinal cord B. To transmit signals related to movement of the hands and feet C.To transport blood to the brain D. To transport oxygen and nutrients throughout the body
Answer:
The peripheral nervous system (PNS) is one of the two components of the nervous system, the other part is the central nervous system (CNS). The PNS consists of the nerves and ganglia outside the brain and spinal cord.[1] The main function of the PNS is to connect the CNS to the limbs and organs, essentially serving as a relay between the brain and spinal cord and the rest of the body.[2] Unlike the CNS, the PNS is not protected by the vertebral column and skull, or by the blood–brain barrier, which leaves it exposed to toxins and mechanical injuries. The peripheral nervous system is divided into the somatic nervous system and the autonomic nervous system. In the somatic nervous system, the cranial nerves are part of the PNS with the exception of the optic nerve(cranial nerve II), along with the retina. The second cranial nerve is not a true peripheral nerve but a tract of the diencephalon.[3]Cranial nerve ganglia originated in the CNS. However, the remaining ten cranial nerve axons extend beyond the brain and are therefore considered part of the PNS.[4] The autonomic nervous system is an involuntary control of smooth muscle and glands. The connection between CNS and organs allows the system to be in two different functional states: sympathetic and parasympathetic
