Answer: A form of asexual reproduction used by bacteria
Explanation:
Binary fission is a form of asexual reproduction used by bacteria to carry out cell division. The results is the cell division used as a method of propagation of the original cell to produce two new cells. The bacteria duplicates its genetic material and then divides into two parts, with each new organism receiving one copy of it. So binary fission creates identical daughter cells.
The steps involved are:
DNA uncoils and duplicates DNA is separated towards the poles of the bacteriaA new cell wall separates the bacterium The new daughter cells now has tightly coiled DNA rodsOnly 10 percent of the energy stored in an organism can be passed on to the next trophic level. of the remaining energy, some is used for the organisms life processes and the rest is...
The rest is eliminated as heat.
Answer:
the rest is eliminated as heat.
Explanation:
We can see that energy is passed to each organism in the food chain in a unidirectional way, always following the producer → decomposer direction. It is important to note that less energy is spent at each trophic level. Normally, only 5% to 10% of energy is passed to the next trophic level, and this phenomenon is called ecological efficiency. Given this low amount of transferable energy, a food chain hardly has more than five trophic levels. Most of the energy stored by the body at a trophic level is used in the body's metabolic processes, in addition, a part of the energy is eliminated in the form of heat.

what is the function of the optic chiasm?
It helps with the optic nerve, if you give me options i can help answer. Sorry if I didnt help :)
Final answer:
The optic chiasm is where the optic nerves from each eye meet and cross, allowing for the correct sorting of visual information to the opposite hemispheres of the brain, which is crucial for coordinated binocular vision and peripheral field perception.
Explanation:
The optic chiasm is a crucial neurological structure responsible for the proper processing of visual information. The optic nerves from both eyes enter the brain and intersect at the optic chiasm, an X-shaped structure located just beneath the cerebral cortex. This arrangement is pivotal for the sorting of visual information. At the optic chiasm, the nerve fibers carrying information from the right half of the visual field of both eyes project to the left side of the brain, while fibers carrying information from the left visual field project to the right side. This crossing of fibers allows for the coordination of visual information and is essential for binocular vision. Moreover, this decussation of nerve fibers is imperative for processing peripheral vision, as the medial retinae—which provide the peripheral visual input—cross over at this point.
Any damage to the optic chiasm can lead to deficits in visual field perception, such as loss of peripheral vision, which could be caused by a pituitary tumor pressing on the chiasm. Understanding the function and the potential implications of damage to the optic chiasm can thus be critical for diagnosing visual pathologies.

Match the characteristics to the blood vessels.
Answer:
Arteries transport blood away to the different parts of the body from the heart. Arteries are the largest blood vessels in the whole body with elastic walls.
Hence arteries match with carries blood away from the heart and largest blood vessel in diameter
Capillaries take blood from various parts of the body. It exchanges nutrients, oxygen, and waste with tissues or cells. These are the smallest blood vessels.
Hence capillary matches with exchanges nutrients with tissues and single walled.
Veins transport the blood to the heart from the body. These vessels have a thin endothelial layer.
Hence Vein matches with carries blood to the heart and has a thin endothelial layer.
characteristics of different blood vessels:Artery: They carry blood away from the heart. They have thick, elastic walls to cope with the high pressure of blood from the heart. They are not very flexible and have a narrow lumen (central space).
Vein: They carry blood towards the heart. They have thinner walls and less elastic fibers than arteries. They have valves to prevent blood from flowing backward. They have a wide lumen (central space).
Capillary: They are the smallest blood vessels. They have a thin wall that only allows for the exchange of gases, nutrients, and waste products between the blood and body cells. They are found throughout the body and link arterioles and venules.

why do plants go through photosynthesis? HELP ASAP!!!!
Final answer:
Plants need to go through photosynthesis to create their own food in the form of glucose using sunlight, carbon dioxide, and water, and to release oxygen as a by-product, essential for the survival of most life forms on Earth.
Explanation:
Plants undergo photosynthesis to produce their own food and supply oxygen to the environment. Photosynthesis is a critical biochemical process that allows plants to harness energy from the sun and convert carbon dioxide and water into glucose (a form of sugar) and oxygen. This process not only provides energy for the plant's own growth and development but also supports life on Earth by producing oxygen for other organisms to breathe and organic compounds that serve as food for many forms of life.
Carbon dioxide, water, and sunlight are the primary ingredients for photosynthesis. During this process, glucose is synthesized, which is vital for the plant's survival and growth. Furthermore, the oxygen released as a by-product of photosynthesis contributes to the oxygen supply in our atmosphere, which is essential for the respiration of almost all living creatures, including humans.
Through photosynthesis, plants are able to fix carbon and play a pivotal role in the carbon cycle. They are autotrophs, meaning they produce organic compounds necessary for their metabolic processes without the need to consume other organisms. This sets the foundation for food chains, as other organisms depend on plants for sustenance.
Without photosynthesis, there would be little oxygen in the air, and the energy flow within ecosystems would cease, leading to dire consequences for all life forms. Hence, the importance of photosynthesis extends far beyond the life of plants and supports the complex web of life on our planet.
Two species of shorebirds are both adapted to live in coastal marshes. One species outcompetes the other for the small fish that live within one niche in the marsh. What is likely to happen to the other species of birds?
Answer:
The population of other specie of birds will decline or other specie of birds will find some alternate source of food to survive.
Explanation:
According to the Competitive exclusion principle, which is also known as Gause's Law, two specie living in the same niche and feeding on the same resource cannot co-exist stably.
As we have well studied the theory of natural selection which states that only those organisms survive which have better tendency to compete for food and adapt to the environmental conditions.
Coming towards the question, what wi ll happen when One species outcompetes the other for the small fish , the other specie will not get enough food and will start to die or decline in population. Eventually either other specie needs to find another alternative food source for itself or migrate at some other location where there is less competition otherwise it will just not exist anymore at that niche.

Which type of substances serves as a catalyst for reactions that break large food molecules into smaller useful molecules
Enzymes serve as catalyst that breakdown large substance into smaller molecules. Enzymes are proteins that function as biological catalysts to speed up chemical reactions in an organism.
Answer:
Enzymes.
Explanation:
Enzymes are the substances which play the role of catalysts in bio-chemical reactions. These enzymes are proteins and play a very important role in glycolysis stage of cellular respiration in which large food molecule like glucose is broken down into smaller useful substance like pyruvate. Some enzymes which participate in glycolysis are phosphofructokinase, enolase, pyruvate kinase etc. This pyruvate is further converted into even smaller molecules like Acetyl-CoA which enters the next stage of cellular respiration known as TCA cycle.
TCA cycle produces many intermediates (molecules) which are useful for other bio-synthetic pathways in the body. For example: Alpha-ketoglutarate which is an intermediate of TCA cycle is used in the synthesis of many amino acids like glutamine, proline, and arginine.

Which statement describes potassium-argon dating?
Potassium-argon dating is a method used by geologists to date rocks and minerals. It is based on the decay of isotope potassium-40 to argon-40. It is accurate due to the slow decay rate of K-40 which allows dating of very old materials.
Explanation:Potassium-argon dating is a method used by geologists and archaeologists to date rocks and minerals. It is based on the decay of the isotope potassium-40 (K-40) to argon-40 (Ar-40). The time of decay is set to be the ‘age’ of the rock or mineral. The accuracy of this method is high due to the slow decay rate of K-40, which makes it suitable for dating materials that are millions or even billions of years old.
In this method, the sample is first liquified in a vacuum to drive out any argon gas. It is then reheated in a vacuum and the gas that is given off is measured to determine the amount of Ar-40. The remaining solid sample is also analyzed to determine the amount of K-40. The date of the sample is then calculated based on the ratio of these two isotopes.

what is the difference between variation and adaptation?
An adaptation is an inherited trait that increases an organism's chance of surviving and reproducing in its environment.
An adaptation is an inherited trait that increases an organism's chance of surviving and reproducing in its environment.
Thus, A heritable behavioral, morphological, or physiological characteristic that has developed through natural selection that preserves or improves an organism's fitness under a certain set of environmental conditions is referred to as adaptation.
Biological fitness, which controls the rate of evolution as indicated by changes in gene frequencies, is related to adaptation. When two or more species develop adaptations that interact with those of the other species, like with flowering plants and pollinating insects, they frequently co-adapt and co-evolve.
Features that have developed for one use may be coopted for another, as was the case with dinosaurs' insulating feathers and adaptation.
Thus, An adaptation is an inherited trait that increases an organism's chance of surviving and reproducing in its environment.

which of the following statements best describes what happens during the S phase of the cell cycle?
The S phase of the cell cycle is when DNA replication occurs, resulting in two identical copies of each chromosome (sister chromatids) and the duplication of the centrosome.
Explanation:The S phase, or synthesis phase, of the cell cycle involves the replication of DNA. This is significant because when a cell divides, it is essential that each new cell possesses an exact copy of the DNA. During the S phase, mechanisms result in DNA replication and the formation of two identical copies of each chromosome, known as sister chromatids, firmly attached at the centromeric region. The centrosome, which plays a vital role in dividing the chromosomes during mitosis or meiosis, is also duplicated during the S phase. In animal cells, centrosomes are associated with a pair of rod-like structures known as centrioles, which organize cell division. It is important to note that centrioles are not present in the centrosomes of several eukaryotic species, including plants and most fungi.

During the S phase of the cell cycle, DNA replication occurs, resulting in identical pairs of DNA molecules known as sister chromatids. The centrosome, which aids in chromosome movement during mitosis, is also duplicated during this phase.
Explanation:The statement that best describes what happens during the S phase of the cell cycle is that it involves the process of DNA replication. In the S phase, DNA replication can proceed through the mechanisms that result in the formation of identical pairs of DNA molecules-sister chromatids-that are firmly attached to the centromeric region. The centrosome is also duplicated during the S phase, giving rise to the mitotic spindle, the apparatus that orchestrates the movement of chromosomes during mitosis.
The S phase is vital to the cell division process as it ensures that each daughter cell receives an identical and complete set of DNA. It should be noted that although DNA replication is the central event in the S phase, many other biochemically active processes occur including cell growth and protein synthesis.
