What are two advantages of anaerobic respiration?
The main advantage to anaerobic respiration is that, unlike aerobic respiration which releases energy all at once, anaerobic respiration releases energy in short outbursts when necessary. (when muscle cells can't get enough oxygen) Therefore, your energy lasts a lot longer.
What do you understand by internal respiration?
Internal respiration is a metabolic process in cells where once energy is released then carbon dioxide is produced and absorbed by the blood to be delivered to the lungs.
What are the steps in germination of a seed?
Steps of Seed Germination Seed consists of an embryonic plant that is in resting form. Seed germination is a very important phase in the growth of any plant. It is quite interesting to understand steps of seed germination.You will see a wide variety of trees in your surroundings. Trees play important role in maintaining ecosystem and keeping the environment refreshing and pollution-free. Whenever you watch small or big trees, plants or shrubs, you must be curious about their growth and life cycle. Life cycle of any plant is divided in different phases and seed germination is basic stage to start the growth of plant. You may think that seed is lifeless, but it is not true. It consists of plant in a resting, embryonic condition. Whenever it gets favorable environmental conditions, it starts to germinate. This process occurs through different steps of seed germination. Inactive seed lying in the ground needs warmth, oxygen and water to get developed into plant. Off-course, all the seeds lying in ground are not lucky enough to get proper environment to germinate. Many seeds tend to get dried and cannot develop into a plant. Some seeds get sufficient amount of water, oxygen and warmth and seed germination starts.Seed structureSeed coat is outer covering of seed, which protects embryo from any kind of injury, entry of parasites and prevents it from drying. Seed coat may be thick and hard, or thin and soft. Endosperm is a temporary food supply, which is packed around embryo in the form of cotyledons or seed leaves. Plants are classified as monocots and dicots depending upon number of cotyledons.Requirements for seed germinationAll seeds need adequate quantity of oxygen, water and temperature for germination. Some seeds also need proper light. Some can germinate well in presence of full light, while others may require darkness to start germination. Water is required for vigorous metabolism. Soil temperature is equally important for appropriate germination. Optimum soil temperature for each seed varies species to species.Factors affecting seed germinationThere are several factors that can affect germination process. Over watering can prevent the plant to get enough amount of oxygen. If seed is deeply planted in soil, then it can make to use all the stored energy before reaching soil surface. Dry conditions can prevent germination, as seed doesn't get enough moisture. Some seeds have so hard seed coats that oxygen and water get through it. If soil temperature is extremely low or high, then it can affect or prevent germination process.Steps of seed germinationsProcess of germination occurs in different stages. Some steps of seed germination are as follows:Seed absorbs water and seed coat gets burst. It is the first sign of germination. There is an activation of enzymes, increase in respiration and plant cells get duplicated. A chain of chemical changes starts which leads to development of plant embryo.Chemical energy stored in the form of starch is converted to sugar, which is used during germination process. Soon, embryo gets enlarged and seed coat burst opens.Growing plant emerges out. Tip of root first emerges and helps to anchor the seed in place. It also allows embryo to absorb minerals and water from soil.Some seeds require special treatment of temperature, light or moisture to start germination.Steps of seed germination can be different in dicots and monocots.Germination in dicotsDuring germination process of dicots, primary root emerges through seed coat when seed is buried in soil. Hypocotyl emerges from seed coat through soil. As it grows up, it takes the shape of hairpin, known as hypocotyl arch. Epicotyl structures, plumule, are protected by two cotyledons from any kind of mechanical damage. When hypocotyl arch emerges out from soil, it becomes straight, which is triggered by light. Cotyledons spread apart exposing epicotyl, which contains two primary leaves and apical meristem. In many dicots, cotyledons supplies food stores to developing plant and also turns green to produce more food by the process of photosynthesis.Germination in monocotsDuring germination of grass seeds such as oats or corn, primary root emerges from the seed and fruit and grows down. Then, primary plant's primary leaf grows up. It is protected by a cylindrical, hollow structure known as coleoptile. Once the seedling grows above soil surface, growth of coleoptile is stopped and it is pierced by primary leaf.
What happens to the petals of the flame of the forest flower once the fruit starts to develop?
The petals wither away
What happens to the petals of the flames of the forest flower once the fruit starts to develop?
they will wither and fall off
What is the order of germination?
After a seed is dispersed, it may remain inactive for a while before it germinates. Germination starts when the seed absorbs water from the environment . The embryo then uses its stored food to grow, first the embryo's roots start to grow downward. After that, the stem starts to grow upward and leaves begin to form. Once you can see the plant's leaves, it is a seedling. The environmental factors must also be just right, such as temperature and moisture.
What is microphyl?
A Microphyll is a particular section of the seed that allows water to enter the seed which causes the seed coat to swell and bursts. Once the seed coat has burst, the enzymes starts to become active which begins the process of germination.
What molecule will help in seed germination and prevent the stem from elongating once it reaches the light?
Auxin
Can you skip a period after the first day of getting it?
I am not sure what you are asking. If you are asking can you skip periods the answer is yes. There are birth control pills that have only 4 planned periods a year. But if you are asking to skip a period once it has begun, you can't. You can't stop a period once it starts.
What is something that starts with A and happens once a year?
An annual event starts with A and happens once a year.
What are the advantages if any of anaerobic respiration?
The only advantage of anaerobic respiration is that it releases energy at intervals. This is unlike aerobic respiration which will emit all energy at once.

No additional states seceded from the Union once the war had begun True Or False?

What role does carcinoembryonic antigen testing play after cancer treatment has begun?
Once treatment for the cancer has begun, CEA tests have a valuable role in monitoring the patient's progress.
What does well begun is half done mean?
Beginning a project well makes it easier to do the rest.; Once you have begun a project well, you do not need to put in much more effort to finish it.
Do you put down the salt before or after the snow?
It is smarter to put down salt before the snow comes. Once the snow has begun, it may be harder to melt any ice that has begun to form.
What becomes thicker when you reach puberty?
A boys muscles and penis become thicker once he has begun puberty.
