Answer: cellular membrane: The cell membrane, also called the plasma membrane, is found in all cells and separates the interior of the cell from the outside environment. The cell membrane consists of a lipid bilayer that is semipermeable. The cell membrane regulates the transport of materials entering and exiting the cell.
Explanation:
passive transport Passive transport is a type of membrane transport that does not require energy to move substances across cell membranes. Instead of using cellular energy, like active transport, passive transport relies on the second law of thermodynamics to drive the movement of substances across cell membranes.
Answer:
<h2>1. DdBb</h2><h2>2. ddBb</h2><h2>3. DB, Db, dB and db.</h2><h2>4. dB and db.</h2><h2>5 50% or 1/2</h2><h2>6. 1/8 </h2>
Explanation:
As given, Allele for dimples(D) is dominant over alleles for no dimples (d), so D is dominant over d.
Allele for broad eyebrows (B) is dominant over allele for slender eyebrows (b), so B is dominant over b.
A man heterozygous for both traits ( DdBb) marries a women who has no dimple and heterozygous fro eyebrow (ddBb)
So cross is = DdBb × ddBb
1). Genotype of the man is DdBb.
2). Genotype of the woman is ddBb.
3). Genotype of the gametes produced by the man are DB, Db, dB and db.
4). Genotype of the gametes produced by the woman are dB and db.
5). Probability that their first child will have dimples 50% or 1/2
6). Probability that there first child will have both dimples as well as slender eyebrows 1/8
A result of convergent evolution are the webbed feet of ducks and frogs.
Explanation:
The evolution of the animals, or rather the development of adaptive features, works in very interesting manner. It is very common in nature that animals that are closely related do not share similar characteristics, or the opposite, animals that are not closely related but share similar characteristics. The later case, is referred to as convergent evolution, where totally different animals have developed the same or very similar characteristics in order to be better suited for their environment.
In this case we have the ducks and frogs, and the webbed feet as shared adaptations, or feature. The ducks are birds, while the frogs are amphibians, and their last common ancestor has lived hundreds of millions of years ago. Despite that, both animals have developed webbed feet, and the reason for this has been that both animals have faced the same challenge, swimming and diving, and the webbed feet help them to be much faster and more agile in the water.
Other examples of convergent evolution (in the present and in the past) are:
- Hyena - Tasmanian devil
- Sandy cat - Fenec fox
- Smilodon - Thylacosmilus
- Bats - Birds

Answer: James Watson and Francis Crick
Explanation:
In 1953 James Watson and Francis Crick are responsible for determining the structure of DNA. James and Watson proposed that the DNA is made up of a double polynucleotide chains that are twisted around each other to forming a helical structure. The two DNA chains runs anti-parallel in opposite direction to each other. Like the structure of the ladder.
The answer is James Watson and Francis Crick
