Almost 99% of the mass of the human body is made up of six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus. Only about 0.85% is composed of another five elements: potassium, sulfur, sodium, chlorine, and magnesium. All 11 are necessary for life.

According to the image below, which season is about to begin in the northern hemisphere?
vova2212 [387]

Answer:

winter

Explanation:

On this image, we can see the Earth being tilted away by 23.5 degrees from the Sun. This tilting puts the Northern Hemisphere in a situation where it is the one that is tilted away from the Sun, thus it will receive less sunlight, as well as less direct sunlight. That will cause lower temperatures on the Northern Hemisphere, thus the winter season will start, and it will last for around three months, at least at the mid-latitude zones. On the other side, the Southern Hemisphere is more exposed to the Sun during this tilting, so t receives more sunlight, and more direct sunlight, resulting in summer in this half of the planet.

1) Bacteria respond to changes in their environments, such as nutrient availability, by regulating their metabolic pathways. Des
nasty-shy [4]

Answer:

Examples:

- Short-term adaptation: feedback inhibition

- Long-term adaptation: regulation of gene expression

Explanation:

Feedback inhibition is a mechanism where the product of a chemical reaction is utilized to modulate its own subsequent synthesis. In bacteria, feedback inhibition allows regulating different metabolic pathways in response to environmental conditions by modulating enzyme activity through enzyme reaction products. Moreover, bacteria may also respond to environmental inputs by long-term changes in gene expression. For example, bacteria contain transcription factors activated during stress, which are able to activate the transcription of particular genes into messenger RNAs (mRNAs) that would subsequently be used to generate particular enzymes by the process of translation. These transcription factors may bind to specific DNA motifs in order to promote transcriptional activity, thereby regulating the production of the corresponding enzyme.

A 20-year-old male shoots his hand with a nail gun while replacing roofing shingles. Which of the following cell types would be
Leni [432]

Answer:

The correct answer is b. Neutrophils

Explanation:

Neutrophils are the cells that first reach to the infection side and kills the bacteria. Neutrophils comprises most part of WBCs approximately 50-70% of total WBCs. Neutrophils kills the foreign bacteria by engulfing them and this process is called phagocytosis.

The engulfed bacteria is called phagosome and phagosome then fuse with lysosome making phagolysosome. Now fused lysosome secrete lytic enzymes like proteases, lipases and glycosidases which kills the engulfed bacteria by digesting them.

So neutrophils will be the first cells migrates to prevent bacterial infection in the hand of 20 year old boy who shoots his hand with nail gun.
