Sure lol I’m bored either way ahahah
Answer:
Proteins play a fundamental role for life and are the most versatile and diverse biomolecules. They are essential for the growth of the organism and perform a huge amount of different functions.
The passage of DNA to proteins begins with the step of transforming genetic information into an intermediary between DNA and protein. This intermediary is called messenger RNA (mRNA). The difference between DNA and mRNA is that the second corresponds to a very small fraction of all DNA, consists of a single chain (it is no longer a “zipper” but a strand), and that Thymine (T) is replaced by the Uracil (U). This fraction corresponds to the stretch of DNA that contains the sequence necessary to ultimately synthesize the protein.
Answer choices:
- A frame shift mutation in the X chromosome of a cheek cell
- A chromosomal mutation in the Y chromosome of a kidney cell
- A point mutation in the first chromosome of a sperm cell
- A substitution mutation in the third chromosome of a uterus cell
Answers:
A point mutation in the first chromosome of a sperm cell
Explanation:
Only mutations that affect the germ line are passed on to the next generation. Therefore, only mutations in the egg and sperm of an individual have the potential to affect the next generation.
Mutations in cheek cells, kidney cells, and uterus cells might cause cell death or cancer. This genetic material is not passed on to the next generation, only the egg and sperm contribute this material. Therefore, only mutations here will affect the generation.
Let’s get one thing straight electrons mean negative so I’m going to say very negative cause it spends more time around hydrogen atoms
Hot and Dry
Hot and dry deserts, such as the Sonoran Desert
of Arizona and northwestern Mexico, are warm year-round with an extreme
range of diurnal (daily) temperatures because of low humidity. Brief but
heavy storms may occur seasonally. Soil is hard and rocky. Burrowing
mammals, insects and reptiles are the main fauna. The Great Sandy Desert
of Australia and the Sahara of north Africa fall under this category.
Semi-Arid
Semi-arid
deserts, such as the Great Basin of Nevada and western Utah, have long
dry summers plus winter rainfall. Dew fall may exceed rainfall. Soil is
sandy and rocky, and may include “caliche” (pans of calcium carbonate).
Fauna is consistent with hot and dry deserts.
