Briefly describe he function of the cell parts (organelles)

Answers

Answer 1

Answer: 1.       Cell membrane – mostly in animal cells, the protective layer in every cell
2.       Endoplasmic Reticulum – plays a role in synthesis and production of lipid and protein
3.       Ribosome – These organelles gather and use RNA to synthesize and produce polypeptides and protein
4.       Golgi Apparatus – serves as a courier that packages, modifies and sorts proteins and other materials that it receives from the endoplasmic reticulum
5.       Lysosome – acts a digestive system in cells, it metabolizes and breaks down wasted organelles or materials in the cell
6.       Microtubule – serves as a framework of the cell –cytoskeleton.
7.       Mitochondria – acts as the powerhouse of the cell that uses ATP and converts it to energy
8.       Nucleus – the control center of each cell. It regulates, monitors and organizes the whole cell

The correct option is

The number of organisms being born equals the number of organisms dying.

Explanation:

A population at carrying capacity is neither increasing nor decreasing. When the numbers of individuals in a population of animals, plants or humans exceed their carrying capacity, deaths outnumber births. As the population drops blow carrying capacity, the birth rate grows until births outnumber deaths. Therefore, the number of organisms being born must be equal to the number of organisms dying.

The right answer is C

The carrying capacity (or carrying capacity, or limiting capacity) in ecology is the maximum size of the population of an organism that a given environment can support, ie the capacity of this environment to:

- provide the necessary resources to ensure the sustainability of this species - repair the attacks (pollution, disruption of natural ecological regulations) inflicted by this species on its environment.

At this size a balance will be reached between the number of organisms born and the number of dead organisms.

What are 10 facts about tornadoes?
Science

Answers

A tornado is as a rotating, funnel-shaped cloud that extends from a thunderstorm to the ground with whirling winds that can reach 300 mph.Damage paths of tornadoes can be in excess of one mile wide and 50 miles long.Tornadoes can accompany tropical storms and hurricanes once on land. Its super important to be prepared for a tornado, so make sure you have a disaster plan for your pets too! Sign up for Save Our Pets.Rotating thunderstorms are the best predictors of tornado activity.They are well defined thunderstorms on radar that may include hail, severe winds, lightning, or flash floods.Tornadoes can occur when a warm front meets a cold front, forming a thunderstorm, which then can spawn 1 or more “twisters."Most twisters or cyclones travel from southwest to northeast and can move in the opposite direction for short periods of time. A tornado can even backtrack if it is hit by winds from the eye of the thunderstorm.Funnel clouds usually last less than 10 minutes before dissipating, and many only last several seconds. On rare occasion, cyclones can last for over an hour.A tornado may appear nearly transparent until dust and debris are picked up or a cloud forms within the funnel.Twisters strike predominantly along Tornado Alley — a flat stretch of land from western Texas to North Dakota. This region is a hotspot for tornadoes because the dry polar air from Canada meets the warm moist tropical air from the Gulf of Mexico.Tornadoes are most likely to occur between 3 pm and 9 pm, but can occur at any time.In the southern states, peak tornado occurrence is March through May, while peak months in the northernmost states are late June through August.

1. Natural disasters
2. Form in warm places
3. Are dangerous
4. You may also go through a thunderstorm too
5.Can cost alot of money to repair what the tornado has done
6. May cost lives
7. Can travel a long distance
8. May continue for days
9. It is a type of storm
10. Tornadoes can affect people in different places

What is difference between Respiration and Breathing??...Give 2 points each.

Answers

Breathing is simply taking in of oxygen and expelling out carbon dioxide. It involves nose, larynx, bronchi, broncioles, lungs and alveoli.

Respiration is a deeper process. It involves oxidation of food in the mitochondria and releasing ATP for energy requirements. It involves many organs or perhaps the whole body

The difference between breathing and respiration is that when you breathe you take in oxygen and expel carbon dioxide while during respiration the body breaks down the oxygen so that your cells can use it for energy.

All living things are either Eukarya, Bacteria, or Archaea. These three broadest categories in the classification of life are called _______.

Answers

All living things are either Eukarya, Bacteria or Archaea. These three broadest categories in the classification of life are called domains. Classifying organisms is nothing new for people as people have been concerned about classifying organisms for thousands of years. Aristotle the Greek philosopher was the first person to have classified organisms about 2000 years ago. Aristotle’s classification is still used today for classifying any new organisms that are discovered. Later on Carl Linnaeus worked on the already discovered model of Aristotle to create a different kind of classification system.
