short-day plants, long-day plants, and day-neutral plants.
Flowering is the most well-studied manifestation of photoperiodism in plants, additional reactions to day length include bud dormancy and bulb or tuber initiation.
What is photoperiodism?Long-day vegetation Long-day plants (LDP) and short-day plants are the two terms used to describe plants that require longer exposure to light. Short-day plants (SDP) or Day Neutral Plants are those that require less exposure to light.
Positive and negative phototropism are the two varieties. Positive phototropism is the growth in the direction of a light source, whereas negative phototropism is the growth in the opposite direction.
Therefore, negative phototropism is a characteristic of plant roots that arise from the necessity for them to stoke deeper roots for the plant's stability, water, and nutrients.

Which of the following statements correctly matches a cell part with its function?
A). The cell membrane packages lipids for export while the mitochondria modifies
and packages proteins.
B). The mitochondria perform photosynthesis while the chloroplasts perform
cellular respiration.
C). The nucleus stores genetic information while the Golgi apparatus sorts and
packages products for distribution.
D). The nucleus produces energy while the ribosomes direct the activities of the
cell.
C
The "Nucleus" contains the genetic information of the cell in the form of deoxyribonucleic acid (DNA) or chromosomes and thus, controls cell growth and multiplication. It is also the site of DNA replication (formation of an identical copy of DNA).
While the "Golgi apparatus", or Golgi complex, functions as a factory in which proteins received from the ER are further processed and sorted for transport to their eventual destinations: lysosomes, the plasma membrane, or secretion.
Brefly explain Endogenous antigen & examples & autoantigen
Exogenous antigens refer to the antigens that enter the body of the organism from the outside while endogenous antigens refer to the antigens produced from within the cell as a part of normal cell metabolism or when the cell is infected by bacteria or viruses.
Examples
viral proteins produced during viral replication;
proteins produced by intracellular bacteria such as Rickettsias and Chlamydias during their replication;
proteins that have escaped into the cytosol from the phagosome of phagocytes such as antigen-presenting cells;

Explain what would be the effect of having stratified epithelium in the alveoli of the respiratory system?
The alveoli needs of the epithelium for the gaseous exchange and stratified squamous epithelium are formed of multiple layers the difficulty in a gaseous exchange
If alveolar tissue were manufactured of stratified epithelium rather than simple squamous epithelium, oxygen diffusion would be reduced.
What is stratified epithelium?A stratified epithelium is a type of epithelial tissue made up of multiple layers of epithelial cells.
The only layer in contact with the basal lamina is the basal layer. This layer also undergoes mitotic division, resulting in cells in the upper layers.
Depending on their origin, the primary functions of the respiratory epithelium are to moisten, safeguard the airway tract from harmful microorganisms, infections, and tissue injury, and facilitate gas exchange.
Oxygen diffusion would be reduced if alveolar tissue were made of stratified epithelium rather than simple squamous epithelium.
Because of the multiple cell layers, oxygen would have to travel a greater distance to diffuse from the alveoli.
Thus, these can be the effect of having stratified epithelium in the alveoli of the respiratory system.

You are studying a protein that you think functions as a protease. You know the genetic code and amino acid sequence for the protein and you hypothesize that a serine is critical to the enzyme's function. Describe an experiment or set of experiments that would test your hypothesis.
It is possible to remove serine by targeting mutagenesis and then observe how this modification changes the function of the protein in the cell. Serine is often a target for phosphorylation.
What is serine?Serine is one fundamental amino acid, i.e., a building block of biomolecules called proteins.
Serine is often a target for posttranslational modifications, especially protein phosphorylation.
In a given cell, serine phosphorylation may activate or deactivate specific signaling pathways.
In this case, it is possible to identify other serine proteases by sequence homo-logy using the BLAST bioinformatic tool.

How does a mountain affect weather?
Answer:
Mountains have an impact on climate because they block wind and get more rain than low-lying areas. As air is driven over higher ground, it cools, condensing moisture and falling as rain. The higher above sea level an area is, the colder it is.
Answer:
Mountains can have a significant effect on the amount of rainfall. ... The further up the mountain the colder the temperature. Then, when the air travels back down the mountain it gets warmer and drier, because the moisture in the air dried out during the rise up the mountain. This area gets less rain as a result.
