Note how several of these explanations use catastrophes appearing in religious texts to explain natural events. How does this il
Nitella [24]

Answer:

Some people think that God uses natural catastrophes to punish human beings, other people reject that idea, and there are even those who do not know what to believe. Most religions claim that no one can know a certain science if natural disasters happen or not by divine will.

Explanation:

There is currently no basis for claiming that natural disasters are part of a divine plan to punish humanity. Since God is a sign of justice, he never eliminated the righteous with the wicked, rather, he had measures to help all who obeyed him. On the contrary, natural disasters affected men, women and children, without distinction.

It is obvious that indiscriminate natural disasters do not follow the pattern of divine crises observed in the Scriptures. What's more, it doesn't even harmonize with the personality of God.

You have learned that the fusion of egg and sperm produces a zygote. But how does the sperm reach the egg, and how does the zygo
FrozenT [24]

Answer:

Pollen grain lands on stigma

Explanation:

A) Pollen grain lands on stigma

  • pollen tube grows down the style
  • generative cell divides, forming two sperm
  • two sperm are discharged to them female gametophyte
  • sperm fuse with the egg and two polar nuclei
  • zygote forms and divides into a terminal cell and a basal cell
  • cells of embryo differentiate into three tissue types---- seed dries out and becomes dormant.

B)

  1. During pollination, a pollen grain is transferred from an anther to a stigma. Once the pollen grain lands on a suitable stigma, it germinates and forms a pollen tube, a structure that grows down through the style to the ovary.
  2. Once in the pollen tube, the generative cell from the pollen grain divides by mitosis, forming two sperm. The sperm travel down the pollen tube and are discharged into the female gametophyte. In a process called double fertilization, one sperm fertilizes the egg, forming the zygote; the other sperm fuses with two polar nuclei in the female gametophyte, forming a triploid (3n) nucleus. The zygote develops into the plant embryo, and the triploid nucleus divides and gives rise to the endosperm. Double fertilization prevents the waste of the plant's resources by ensuring that the nutrient-rich endosperm only develops if the egg is fertilized.
  3. After double fertilization, the ovule starts to develop into a seed containing the plant embryo. As the embryo develops, the three tissue systems are established, and the cotyledons (seed leaves) form. The seeds of many species dry out as they mature. These dry seeds lie dormant until suitable germination conditions occur.

max2010maxim [7]

A class of lipids used as chemical messengers, to signal cells to undergo changes, is called Monoglycerides. Its a class of glycerides which are composed of molecules of glycerol linked to fatty acid by easter bond.

Monoglycerides are the type of glyceride and that made up of glycerol and one fatty acid chain. Triglycerides are very similar expect they have three fatty acid chains. Mono and diglycerides may be manufactured through the reaction of plant or animal derived fatty acids with glycerol which breakdown plant or animals which derived fats and oils.

Lipids such as steroid hormones that serve as chemical messengers between cells , tissues and organs and other communicate signals between biochemical system within a single cell.

All of the following are differences in transcription, RNA processing, and translation between prokaryotes and eukaryotes except
Mazyrski [523]

Answer:

the mRNA goes through extensive modifications such as addition of a poly tail and a 5' cap in eukaryotes but not in prokaryotes.

Differences:

- the promoters in prokaryotes have a -35 and -10 box while in eukaryotes they are variable but have a TATA box from  

- the transcription initiation site there is a single RNA polymerase in prokaryotes while eukaryotes have multiple RNA polymerases

- the sigma factor associates with the promoter region in prokaryotes but in eukaryotes there are many basal transcription factors

Explanation:

Ribosomal and transfer RNAs are processed both in prokaryotic and eukaryotic organisms. However, mRNA is only processed in eukaryotes. In eukaryotic cells, mRNA processing involves:

1. Capping at the 5' end. This process has several functions including regulation of nuclear export, prevention of eukaryotic mRNA degradation and promotion of translation.

2. Splicing in order to remove introns and conserve coding exons. Splicing helps to increase the diversity of the eukaryotic mRNAs (and therefore eukaryotic proteins)

3. Polyadenylation by the addition of a poly(A) tail at the 3' end. The poly(A) tail makes the eukaryotic mRNA molecule more stable and also prevents its degradation by exonucleases.
