False: Development of gametes and embryos.
Development is a human process in the sense that people, not material factors, drive development. The energy and ambition of those who seek development are the driving forces behind the development. People's consciousness can determine the direction of development.
- Can be a source of employment. - Contribute to national development and promote the economy. - Helps develop infrastructure. - Contribute to the preservation of cultural heritage.
Helps businesses attract and retain top talent, improve productivity, and help businesses generate more profit through learning and development.

Answer:
The correct answer is: b. Budding of the secretory granule.
Explanation:
- In eukaryotic cells, the pathway by which secretory proteins are produced and are secreted can be explained below:
- The gene {DNA (Deoxyribonucleic Acid) sequence}, located on the genome, encoding the secretory protein is transcribed into an mRNA (messenger Ribonucleic Acid) by the RNA polymerase. This process happens in the Nucleus.
- The mature mRNA is translocated from the nucleus into the cytoplasm.
- In the cytoplasm it associates with the ribosome but translation process does not begin now.
- This is because, as the mRNA sequence has the tag of forming a secretory protein, it can be translated only when the ribosome bound mRNA sequence attaches itself to the ER (Endoplasmic Reticulum).
- On attachment to the ER, the process of translation begins and the polypeptide formed is released into the lumen of the ER.
- The process of glycosylation starts in the ER.
- The glycosylated protein is then transported from the ER in membrane bound vesicles to the cis, medial and trans Golgi, where the process of glycosylation gets completed and the protein gets completely folded.
- After this, secretory vesicles buds off from the Golgi and migrate towards the plasma membrane.
- At the plasma membrane, the secretory vesicles fuse with the plasma membrane and releases the protein out of the cell by the process of Exocytosis.
- In the given question completely folded glycosylated protein is formed but it is not secreted. This means the protein is able to reach to the Golgi bodies. But secretory vesicle formation does not take place.
- Hence the Substance X might inhibit the formation or budding of Secretory Vesicles.
Answer:
Option C. First, an animal eats another organism. Then, food is broken down into smaller molecules. Next, the animal's cells use molecules to make new cells.
Explanation:
When one animal eats another animal, the body of organisms is made of higher molecules such as carbohydrate, protein and lipids. These large molecules are broken down into simpler substances in the stomach such as glucose, amino acid and faty acid. These substances are absorbed by the body and release energy from them.
The answer would be natural selection.
The female deer might consider the large antlers of the male deer to show of certain genetic qualities that have a higher probability of reproduction, as well as a higher social status among deers.
This means that if she picks him as her mate during this season, their offspring will have a better chance of survival compared to her picking another deer with smaller antlers.
This is called natural selection because she will pick the deer that is most adapted to that environment. Thus their offspring can be ensured to have the highest possible probability to survive.
It does not have a nucleus I think
