Answer:
The number of chromosomes in sex cell must be haploid (1n) as compared to body cell which is diploid(2n).
Explanation:
Body cells are diploid while the sex cells are haploid. We can say that sex cells contain half number of chromosomes as compared to body cells.
The number of chromosomes in each s-ex cell is half the number chromosomes in body cells.
Chromosomes:Every cell in the human body contains 23 pairs of such chromosomes; our diploid number is therefore 46, our ‘haploid’ number 23. Of the 23 pairs, 22 are known as autosomes. The 23rd pair is made up of the s-ex- chromosomes, called the ‘X’ and ‘Y’ chromosome. These 46 chromosomes carry the g-enetic information that’s passed from parent to child through heredity.

Answer:
d. cause iron in ocean water and terrestrial rocks to rust (oxidize)
Explanation:
The Great Oxygenation Event (GOE) refers to the introduction of huge amounts of free oxygen into the atmosphere. This phenomenon was caused by photosynthetic cyanobacteria during the Paleoproterozoic, i.e., 2.5–2.2 billion years ago. During this period, oxidized iron minerals appeared in the soil and also were deposited on the deep ocean floor due to reactions with oxygen in the seawater from oceans. Moreover, during the Devonian (approximately 410- 360 million years ago), land plants greened the continents and it had brought higher levels of atmospheric oxygen, thereby increasing the amount of oxidized iron in the soil and rocks.

Membrane proteins offer structural support to the membrane but have no other function. Both plant and animal cell membranes are considered fluid mosaics.
Answer:
- In water, phospholipids spontaneously arrange into a bilayer
- Steroids in cell membranes allow the membrane to be more fluid
- Phospholipid bilayers surround all eukaryotic cells
- Both plant and animal cell membranes are considered fluid mosaics
Explanation:
All living things (i.e.. both eukaryotic and eukaryotic organisms) are composed of cells, and all cells have cell membranes. In an aqueous environment, phospholipids spontaneously form bilayers: hydrophilic heads of phospholipids face the water environment at the surface of the bilayer, while hydrophobic fatty acid chains are shielded from the water in the interior. Steroids are lipids that intercalate into the bilayer of the cell plasma membrane, reducing the fluidity of the membrane. Integral membrane proteins may have different biological roles. For example, permeases are integral membrane proteins that facilitate the diffusion of certain molecules (e.g., glucose) across the cell membrane by passive transport. Both plant and animal cell membranes are considered fluid mosaics where different types of molecules (e.g., phospholipids, cholesterol, proteins, etc) are constantly moving across the membrane.

Dandelions can produce seeds by both asexual and sexual
reproduction.
1. How does this benefit the dandelion?
Answer:
only appear in veg plants
Explanation:
Unlike other forms of asexual reproduction in plants such as vegetative plant propagation via cuttings, apomixis is asexual reproduction via seeds. In the case of most dandelions (i.e., Taraxacum officinale), the embryo in the seed forms without meiosis, thus the offsping are genetically identical to the parent.
one evening you see a crescent shaped moon that looks very narrow. a couple nights later you notice if again but it looks thicker. which phase is it in?
If one sees a crescent-shaped moon that looks very narrow one evening, and a couple of nights later one notices it again, but it looks thicker, then the moon is in the waxing phase as in option A, which is leading to the first quarter phase.
What are the different moon phases?The waxing crescent phase is the phase of the moon that occurs after the new moon phase and before the first quarter phase, where the illuminated part of the moon visible from earth gradually increases in size, and the moon looks narrower on the first evening and thicker on the second evening because the angle between the sun, Earth, and the moon is changing.
Hence, one sees a crescent-shaped moon that looks very narrow one evening, and a couple of nights later one notices it again, but it looks thicker; then the moon is in the waxing phase as present in option A.

Which location has the warmer air temperature: Recife or Lima? Why?
Answer:
Recife has warmer air temperature because it is closer to the equator
Answer:Recife has the warmer air temperature
Explanation:Recife has the warmer air temperature.The first reason is that Recife,Brazil is closer to the equator than Lima,Peru which means Recife will receive more energy from the sun.Another reason is that the ocean currents that pass both locations have different origin.The current that passes Recife originated near the equator so that causes it to bring lots of energy causing the air temperature of Recife to be high and warm.The current that passes Lima originated near the South Pole so that causes it to bring less energy.Also Lima,Peru has upwelling as we see in the map and that also affects Lima,Peru to have colder air temperature
Telling Them Apart Suggest a way to distinguish between the two elements in each of the following pairs.
A. Bacterial cells; archaeal cells
B. Rough ER; smooth ER
C. Animal peroxisomes; leaf peroxisomes
D. Peroxisomes; lysosomes
E. Viruses; viroids
F. Polio virus; herpes simplex virus
G. Eukaryotic ribosomes; bacterial ribosomes
Answer:
A. presence or absence of phytanyl groups linked to glycerol
B. presence or absence of ribosomes
C. presence or absence of enzymes involved in photorespiration
D. presence or absence of catalase
E. presence or absence of coat proteins
F: Poliovirus's genetic material consists of RNA, while HSV's genetic material consists of double-stranded DNA
G. eukaryotic ribosomes and prokaryotic ribosomes have different sedimentation coefficients
Explanation:
Bacteria and Archaea are both prokaryotic organisms, but they have a different composition in their cell membranes. Archaeal membranes contain phytanyl groups linked to glycerol, while bacterial membranes contain fatty acids linked to glycerol. The rough endoplasmic reticulum (RER) has ribosomes (i.e., organelles that act to synthesize proteins), while the smooth endoplasmic reticulum lacks ribosomes. The leaf peroxisomes contain enzymes exclusively involved in photorespiration such as glycolate oxidase (GLO), which lacks in animal peroxisomes. Moreover, peroxisomes contain catalase, an enzyme that decomposes hydrogen peroxide (H2O2) to convert it into water, while lysosomes contain hydrolytic enzymes such as, for example, cathepsin proteases that degrade proteins. Viruses are composed of nucleic acids (either DNA and RNA) and coat proteins (capsids) while viroids consist only of RNA. Poliovirus is an Enterovirus (Picornaviridae family) whose genetic material consists of a single-stranded positive-sense RNA genome, while the genetic material of the Herpes Simplex Virus (Herpesviridae family) is double-stranded DNA. Finally, eukaryotic ribosomes have different sedimentation coefficients than their prokaryotic counterparts: prokaryotes have 70S ribosomes while eukaryotes contain larger 80S ribosomes.
