B. Effective against all pathogens
This statement is true.
In the case of autosomal dominant disease, the person is either homozygous (which is very rare) or heterozygous. On the molecular level, either the mutation produced a new deleterious protein for the organism, or the mutation affected an existing protein in the physiological state and that a 50% activity is not enough to compensate for the needs. of the body.
In case of autosomal recessive disease, the sick person is always homozygous. If the two loci each have a different mutant allele, it is called a "composite heterozygote". People with autosomal recessive inheritance disorder have "mandatory heterozygote" parents.
Answer: Lipids
Explanation: The ratio of saturated and unsaturated fatty acids (lipids) determines the fluidity in the membrane at cold temperature.
Answer:
Chloroplast
its function is to create chemical energy using light energy
Explanation:
Photosynthesis occurs in chloroplasts which can be compared to mitochondria because they both produce energy for the organism. The Chloroplast contains within it a pigment, chlorophyll which captures the sun's energy and turns into energy which is used to create other parts of photosynthesis. Chloroplasts capture light energy from the sun to produce the free energy stored in ATP and NADPH through a process called photosynthesis. Chloroplasts are one of the many organelles found in the body, and are generally considered to have originated as endosymbiotic cyanobacteria. In this aspect, they are similar to mitochondria but are found only in plants and protist.
