Exercise increase oxygen intake by the cells as it increases blood flow. the correct option is A.
Thus, Exercise improves blood flow, which in turn enhances cellular oxygen uptake. Our heart rates increase and more blood is pushed through the body while we exercise.
The cells receive more oxygen thanks to the increased blood flow, which enables them to fulfill the higher energy demands of physical exercise.
Carbon monoxide does not increase oxygen intake during exercise and instead is a harmful chemical that hinders the body's ability to transfer oxygen.
Thus, Exercise increase oxygen intake by the cells as it increases blood flow. the correct option is A.

e. that species has many natural predators?
The given question is incomplete. The complete question is:
All of the flower mechanisms would help prevent pollination by a foreign species except __________.
A. A pollen tube grows in the style of its own species.
B. The stigma is sticky mainly to its own species of pollen.
C. The timing of flowering keeps pollinators moving among a limited number of species.
D. Flowers attract a small number of specialized pollinators, and therefore pollen is not spread equally to all available species of flowers.
E. Flowers of different species are the same color and attract similar pollinators.
Answer:
E. Flowers of different species are the same color and attract similar pollinators.
Explanation:
Plants of different species develop various morphological, physiological and behavioral strategies to ensure that the flowers of one species are not pollinated by pollens from any other species. One such structural adaptation is the production of flowers of a different color, size and shape.
These structural distinctions allow specific pollinators to visit the flowers of the particular species only. It ensures pollens from a different plant species do not land on the flowers of some other species. Production of flowers of the same color by different plant species would attract same pollinators and may result in pollination by a foreign species.
Answer & explanation:
The decomposition reaction occurs when a compound, by spontaneous (if unstable) or non-spontaneous (if stable) action, when chemically defragmented, generates two new products.
For example:
2AB (s)* → 2A (s) + 2B (g)*
*s is for solid and g for gas
This reaction shows a simple compound AB decomposing into two substances A and B.
What often occurs in decomposition reactions is the formation of a gas (g) and its release after the reaction, due to the fact that the compounds are formed by electron(e⁻) affinity, and gases are extremely electronegative.
B. Possesses the characteristic of compartmentalization of organelles, wherein the organelles are bound by membranes.
C. Possesses simple duplex DNA in the form of a circular loop.
Possesses the characteristic of compartmentalization of organelles, wherein the organelles are bound by membranes. The correct option is B.
Eukaryota is a varied domain of creatures whose cells have a nucleus, and its members are referred to as eukaryotes.
Eukaryotes include all animals, all plants, all fungi, and many unicellular creatures. They are a part of the Eukaryota or Eukarya group of organisms, one of the three categories of life.
Animals, fungi, plants, and protists all have eukaryotic cells. DNA is typically housed in the nucleus, an organelle that is encircled by a membrane known as the nuclearenvelope.
A nuclear membrane is present in eukaryotic cells. It has a cell wall, mitochondria, and Golgibodies.
It also has cilia and flagella, which are locomotory organs. The DNA in the nucleus contains all of the genetic data.
Thus, the correct option is B.
