B. Multicellularity
C. Cell walls made from sugars
D. Autotrophy
E. Motility (ability of locomotion)
F. Heterotrophy
Answer:
Multicellularity
Autotrophy
Membrane-bound Nuclei
Explanation:
This kingdom of plantae comprises of the more familiar green plants. They are multicellular organisms which contain the green light-trapping pigment called chlorophyll. They make their own food from carbon dioxide, water and mineral salts using sunlight energy, a process called photosynthesis. Thus plants are said to autotrophic.
Answer:
do u know
Explanation:
Sometimes the cuttings wouldn't grow because of infertile soil or because the plant is unhealthy and cant attach itself to gather nutrients.
Hope this helps!
Answer:
Oxygen is essential for respiration because the body uses it to 'burn' food molecules. Animals take in oxygen when inhaling and give off carbon dioxide when exhaling. ... This is why rescue breathing works - it can supply a non breathing patient with enough oxygen to support life.Nitrogen is essential for all living things because it is a major part of amino acids, which are the building blocks of proteins and of nucleic acids such as DNA, which transfers genetic information to subsequent generations of organisms.
Explanation:
Free oxygen can be problematic for organisms due to its high reactivity and the production of reactive oxygen species (ROS), causing oxidative stress and various health problems. Excess free oxygen can lead to diseases in humans, while some organisms cannot tolerate free oxygen at all and will die if exposed to it.
Free oxygen can be a problem for many organisms due to its high reactivity. In aerobic organisms, free oxygen can lead to the production of reactive oxygen species (ROS) such as superoxide radicals, hydrogen peroxide, and hydroxyl radicals, which can damage cellular structures and molecules, including proteins, lipids, and DNA. This can result in oxidative stress and lead to various health problems.
For example, in humans, excess free oxygen can cause damage to cells and tissues, leading to diseases such as cancer, cardiovascular disease, and neurodegenerative diseases. Organisms that have evolved to survive in low-oxygen environments, such as certain bacteria and parasites, may be particularly sensitive to the presence of free oxygen and can even be killed by exposure to high levels of it.
In contrast, other organisms, such as obligate anaerobes, cannot tolerate the presence of free oxygen at all and will die if exposed to it. These organisms lack the enzymes and metabolic pathways required to deal with the toxic effects of oxygen. Examples of obligate anaerobes include some types of bacteria that live in environments without oxygen, such as deep-sea hydrothermal vents or the intestines of animals.

TCA or the citric acid cycle is a biochemical step in which the saved energy is released by the oxidation of Acetyl Co-A in the cells.
The correct answer is:
Option C. Acetyl Co-A.
This can be explained as:
Therefore, pyruvic acid must be converted into acetyl CoA for the cycle to proceed.
To learn more about acetyl CoA and Krebs cycle refer to the link:
B. biomass
C. trophic
D. organic
Living material that makes up organisms is known as biomass. The correct option is B.
Biomass is the word used for the energy that is produced by biological matter, plants and animals, and other organisms. The energy produced by the households matters.
The biomass on burning releases carbon dioxide, so it is not good energy for the environment.
Thus, option B. biomass is correct.
