Answer:

1) Homologous chromosomes are chromosomes that are the same in size and shape and control the same characteristics; occur in pairs in higher animals and plants

2) Internal fertilization is a mating pattern in which the male and female come close together, the male introduces the sperm into the body of the female, and fertilization occurs. It is practiced by mammals like goat, sheep etc

3) Pollination is the transfer of pollen from male to female cones in gymnosperms, or from anther to stigma in flowering plants. It is effected by insects, birds, bats and the wind.

4) Zygote is the result of fertilization in which two gametes have fused together; often simply called a fertilized egg.

What happens when light doesn’t spread out?

Gelneren [198K]

Spreading out a wave over a larger area just causes the wave strength to weaken, but does not cause gaps to form. Therefore, if you look at photons as waves, spatial gaps never form in light as it travels through free space, no matter how dim it gets.

Which of the following best represents a function of a lipid within an organism? O Lipids are components of cell membranes All t

Rashid [163]

Answer:

The statement that best represents a function of lipids within an organism is that they are components of cell membranes.

Explanation:

Lipids are biomolecules formed by the binding of fatty acids, important for structure, compound synthesis and energy reserve.

In living beings, one of the most important functions of lipids is to be the main component of cell membranes.

Specifically, phospholipids associate to form a double layer, called lipid bilayer, capable of acting as a semi-permeable membrane, due to its non-polar or hydrophobic character. In this way, membrane lipids fulfill a structural and protective function of the cell and its contents.

Regarding the other options:

Proteins are made up of amino acids, not lipids.
Lipids are not constituents of the DNA structure.
