Answer:
mostly hydrophobic
Explanation:
A membrane is made of amphipathic molecules with the hydrophobic part pointing to the lumen and cytosol and the hydrophobic part (much bigger makes up most of the membrane) in the middle, the protein chains that are embedded in the membrane are thus mostly hydrophobic because the membrane is mostly hydrophobic and like likes like
Breast milk provides antibodies to fight diseases.
Breast milk is produced by mammary glands in the breasts and its main function is feeding an infant. Breast milk is the primary source of nutrition for newborns. The composition of the milk includes immune-boosting white blood cells, as well as stem cells, which can help organs develop, antibodies, proteins, amino-acids, oligosaccharides, growth factors, hormones, enzymes, vitamins, minerals…

Answer:
The correct answer is: Yes, this is an example of Reproductive Isolation.
Explanation:
- Reproductive Isolation can be defined as the mechanism adopted by different species during the course of their evolution, due to which the individuals belonging to different species are incapable of mating with each other and producing viable offspring.
- The given question is an example of Mechanical, Pre-zygotic Reproductive Isolation.
- Prezygotic Isolation refers to the mechanism adopted by individuals of different species during the course of evolution such that successful fertilisation of gametes from individuals of different species never occur, hence a viable zygote is never formed.
- Mechanical Isolation refers to the mechanism adopted by individuals of different species during the course of evolution such that their reproductive organs or the organs that assist in the process of reproduction are incompatible to each other. Hence, the gametes of each species are unable to come in vicinity of each other.
- Here, the pollen grain from the flower of one species of juniper is unable to form the pollen tube when its sits on the stigma of the flower of another species of juniper. This is an example of Mechanical Isolation.
Answer:
c and d
Explanation:
<u>A species of an organism with cell wall that lacks peptidoglycan is definitely not a bacterium because bacterial cell walls usually have peptidoglycan.</u>
One particular group of organisms whose cells have cell walls but lack peptidoglycan is Archaea.
<em>Archaea represents a group of prokaryotes that are able to survive in extreme conditions such as high temperature, pressure and salinity. As such, they could inhabit hydrothermal springs as well as alkaline hot springs.</em>
Hence, thermoacidophile <em>Sulfolobus acidocaldarius </em>is likely to be an Archaea and could inhabit both hydrothermal springs and alkaline hot springs.
The correct option is option c and d.
