<span>The reactions of the Calvin cycle take place in
the stroma and the process is fueled by and dependent on ATP and NADPH from the
light reactions</span>. However, carbon atom from Co2 are fixed and used to
build three carbon sugars.
Answer:
a. Nucleolus: The nucleolus refers to a composition, which develops with the assistance of the nucleolar organizer region present in the eukaryotes. It constitutes protein and ribosomal DNA and is a location where the generation of ribosomes takes place.
b. Centromere: The prime function of the centromere is to function as the point of attachment for sister chromatids and is a place where the attachment of chromosomes and spindle fibers takes place. The differentiation of centromere takes place at the time of mitosis and meiosis II, which helps in the distribution of chromosomal substances to the daughter cells.
c. Ribosome: The ribosome refers to the composition where different forms of RNAs, enzymes and other components help in the alignment of the primary sequence of a specific protein.
d. Chromatin: Chromatin constitutes the genetic information, which helps in sustaining hereditary information and generation of a phenotype.
e. Centriole: The centriole refers to a cytoplasmic composition, which via the help of spindle fibers assists in the migration of chromosomes at the time of meiosis and mitosis, mainly in the animal cells.
f. Mitochondria: The mitochondrion refers to a membrane-bound composition situated in the eukaryotic cytoplasm. It is the place where the production of huge amounts of ATP takes place via the process of oxidative phosphorylation.
There are a couple features unique to mammals, here are some:
1. Mammary Glands- evolved from modified sweats glands, these are used to create milk for offspring. Only females produce this milk.
2. Hair- this is an adaptation that provides insulation to keep the animal warm, provide protection of the skin, and sometimes camouflage the animal through the hair's color patterns.
3. Sweat glands- while being unique to mammals, they are not present in all of them. For example, whales do not have sweat glands at all because they live in the ocean!
A portal of entry<span> is the site through which micro-organisms enter the susceptible host and cause disease/infection. Infectious agents enter the body through various </span>portals<span>, including the mucous membranes, the skin, the respiratory and the gastrointestinal tracts.</span>
The first one. Becuse there are more grey particuls, wich difuse faster.
