Answer: wings: Insecta class
Chewing mouthparts: some orders in the insects class;
Jointed appendages: common to all athropods
Number of legs: not all the same in some class and even orders
Segmented bodies: common to all
Exoskeleton: common to all
Explanation:
Memeberss in the phylum athropoda all have exoskeleton with itsain component being chitin. They all have segmented bodies; some head, thorax and abdomen like insects, some head, cephalothorax and abdomen like in the crustaceans. All have jointed appendages. Some class possess wings eg insecta and some possess chewing mouthparts egg grasshopers in the class insecta
Answer:
population I stars.
Explanation:
A star is a giant astronomical or celestial object that is comprised of a luminous sphere of plasma, binded together by its own gravitational force.
It is typically made up of two (2) main hot gas, Hydrogen (H) and Helium (He).
The luminosity of a star can be defined as the total amount of light radiated by the star per second and it is measured in watts (w). Also, the apparent brightness of a star is a measure of the rate at which radiated energy from a star reaches an observer on Earth per square meter per second. The apparent brightness of a star is typically measured in watts per square meter.
Some of the examples of stars are; Canopus, Sun (closest to the Earth), Betelgeus, Antares, Vega etc.
New stars that are found in the spiral arms and formed from recycled dead star material are known as population I stars. Also, it comprises of association and clusters formed a million or billion years ago in the spiral arms of Milky Way galaxy.
A galaxy can be defined as a collection or group of many billions of stars and other planetary body which are existing independently.
The correct statements are
a.The female plant produces some gametes that are homoplasmic.
c.The female plant produces some gametes that are heteroplasmic.
e.Leaf phenotype is determined by the number of normal or mutant chloroplasts inherited from the female parent.
Explanation:
The results clearly indicated that the phenotype of the progeny was clearly dependent on the female parent.
This is because the females have egg cells which are larger than the male’s pollens. Due to this large size, female egg cells have cellular organelles like mitochondria, chloroplasts etc; whereas, the smaller male cells are devoid of any organelle.
The variegation in a leaf depends upon the chloroplasts present in it and since only the female cells contain chloroplasts. The appearance of the green color depends upon the chlorophyll in the chloroplasts.
Hence when green leaves were propagated, the progeny also had green leaves. This clearly proves that the leaf phenotype is based on the female parent’s chloroplasts and homoplasmic or heteroplasmic phenotypes are accordingly produced in the progeny due to the female parent.
The female plant cannot be homozygous in some cells or heterozygous in other cells and need not be only heterozygous; the phenotype of the gamete only differs according to the female parent.
Answer:
Explanation:
A phospholipid is a type of lipid molecule that is the main component of the cell membrane. Lipids are molecules that include fats, waxes, and some vitamins, among others. Each phospholipid is made up of two fatty acids, a phosphate group, and a glycerol molecule. When many phospholipids line up, they form a double layer that is characteristic of all cell membranes.
A phospholipid is made up of two fatty acid tails and a phosphate group head. Fatty acids are long chains that are mostly made up of hydrogen and carbon, while phosphate groups consist of a phosphorus molecule with four oxygen molecules attached. These two components of the phospholipid are connected via a third molecule, glycerol.
