The sexual reproduction helps in having more variation among the offsprings. It also makes the offsprings more resistant to genetic diseases.
<h3><u>Explanation</u>:</h3>
Sexual reproduction is the process by which the gametes of the species fused together to form zygote which develops into an offspring. This offspring produced has the gene from both the parents . This genetic setup is not only copied from the parents but they undergo the crossing over and independent assortment which leads to variation among the offspring itself as well as they differ from their parents too.
This variation among the offspring as well as the crossing over helps to eleminate the lethal genes from the genetic pool. Thereby they help to get more resistance among the offsprings from diseases.
Answer:
The correct answer is C eukaryotes have a greater variety of genetic material than prokaryotes.
Explanation:
Prokaryotic cells consist of single chromosome and their DNA is present in a dense region called nucleoid.As one copy of each gene is present in the chromosome prokaryotic cells are haploid.The DNA of prokaryotic cells are circular
Whereas eukaryotic DNA is linear and multiple distinct chromosomes are present in eukaryotes.Two copies of each chromosome are present are in many eukaryotic cells.As a result the eukaryotic cells are diploid in nature.
Due to this greater variety of genetic material the domain eukarya are more complex than archea and or bacteria domains.
Then the model will become useless. originally the bottle should be air tight only tubes connected to the balloons, so that pressure can be shown when you adjust the plastic sheet in the bottom of the model. but now if there's a hole, air can move freely in or out the bottle and the model will not be able to show anything that occurs during respiration
The
correct answer is in the form of chylomicrons.

fats are resynthesized into triglycerides inside the epithelial cells, and
there they're coated by proteins. Such structures are called chylomicrons (small
globules composed of protein and lipid). The chylomicron is water-soluble and
that allows it to travel outside of the cell and enter the lymphatic
capillaries-lacteals.</span>
Answer:
Double fertilization produces a diploid sporophyte and a triploid endosperm. (Ans. C)
Explanation:
Angiosperm are plants which is known for flowering plant on the earth. The flower is reproductive parts of the angiosperm plant. They are including 4 basic parts of the flower: Carpel, Stamens, Sepals and Petals.
During angiosperm plant reproduction, 2 structure are formed which are known as the Endosperm and a Zygote. Later a Zygote will grow and form a embryo and the endosperm is known for food source of plant embryo. Endosperm and Zygote forming process is known as double fertilization and it is a unique process found in angiosperms.
Steps involved in double fertilization are:
1) The pollen tube processing to release 2 sperm cells into an unfertilized ovule.
2) When one sperm cell fuses with the eggs to the formation of zygote and another sperm fuses with the 2 polar nuclei to the formation of endosperm this process is known as double fertilization.
3) After the completion of double fertilization, a fruit and seed develop.
