Both abiotic and biotic factors determine both where an organism can live and how much a population can grow. A limiting factor is a factor that restricts the size of a population from reaching its full potential
The amount of food & water in a habitat is an example of a limiting factor. Other factors include geographical space, predation, climate, competition (for prey, food, mates) etc. An example of a limiting factor is sunlight in the rainforest, where growth is limited to all plants in the understory unless more light becomes available. Or perhaps in a deciduous forest, there are not enough rabbits to support the growth of more foxes. All species within an ecosystem will experience some kind of limiting factors to prevent continuous and exponential growth. (Even humans) Environmental changes (i.e drought, famine, human destruction) results in decreased rates of physiological processes, lowering the potential for survival, growth, or reproduction. Species will undergo Acclimatization to adjust to the new limiting factors through changing their behavior or physiology.
It would hard to live and you would be sick no protection I hope this helps
Answer:
c. lack the enzyme needed to break down cellulose
Explanation:
Starch is the form of carbohydrate which is taken through food by humans and animals and digested by them. Amylase is the enzyme that is used to digest starch in them.
Wood is made up of cellulose and the enzyme which is used to digest cellulose is cellulase. Humans and animals do not have cellulase enzymes therefore they are not able to digest and breakdown cellulose.
Therefore as humans and animals lack enzymes needed to digest cellulose they can not digest wood.
Answer No 1:
Neutral fats such as triglycerides are made up of chains of fatty acids. These molecules are used for storing energy in the body. Also, as they form layers of fat in the body, they provide insulation to the body.
Any extra calories that are not required by our body are converted into triglycerides. The molecules of triglycerides are then stored in our body and used upon need.
Answer No 2:
Lipids are organic molecules that are<u> insoluble </u>in water.
Lipids can be described as a class of macromolecules which do not dissolve in water bur can dissolve in non-polar solvents. The lipids are the main constituent of cell membranes and also are involved in storing energy.Lipids are also used for cell signalling.
Answer:
<u>Passive immunity</u> is passed from a mother’s breast milk to her nursing infant.
Anne Marie recently had a baby girl. She has read all about the benefits of breastfeeding her newborn. Anne Marie knows that her milk can help keep her newborn from contracting a disease. She talks with the baby’s pediatrician, who confirms that the infant will receive temporary Passive Immunity from antibodies transferred in Anne Marie’s breast milk.
Explanation:
Passive immunity can be described as a kind of immunity in which a person gets immunity or antibodies from another source rather than his/her own body producing the immune cells. Active immunity can be described as an immunity which is triggered by a person's own immune cells.
In infants, mothers pass on antibodies to the child by breastfeeding. Hence, it is a type of passive immunity. Passive immunity cannot be as long-lasting as active immunity. It only lasts for some weeks.
