Regulation of gene expression involves process by which a cell determines which genes, among the numerous genes in its genetic make-up, are "switched on" (expressed).
The option that demonstrate that gene expression is regulated is that Cells do not transcribe all of their genes all of the time.
In eukaryotes, regulation of gene expression can take place at various points. This might include post transcriptional and post-translational modifications. This mechanism ensures to control some various processes which include:
When a gene is expressed to produce RNA and protein,Amount of the protein is produced, And when the protein is no longer required.Learn more about gene expression: https://brainly.com/question/25703686

Explanation:
what is mutation? why are mutations more serious when they occur in a sex cell?
Answer:
A mutation is the changing of the structure of a gene, resulting in a variant form that may be transmitted to subsequent generations, caused by the alteration of single base units in DNA, or the deletion, insertion, or rearrangement of larger sections of genes or chromosomes. Mutations in sex cells are more serious because they are heritable and affect the next generation.

5. Knowing that acid rain has a pH of 2-3, would you conclude that crop species with a narrow soil pH range are in trouble? Is acid rain a problem for plant species and crops?
Answer:
Yes
Explanation:
Unless the crops acidity range is that of the rain( which it wouldn't be) it would throw off the crops Ph balance and harm it.
Yes, crop species with a narrow soil pH range are potentially in trouble due to acid rain. Acid rain can have harmful effects on plant growth and productivity. The acidity of the rain can change the pH level of the soil, making it more acidic and less hospitable for plants.
What is acid rain?Acid rain is a type of rain or other precipitation that is unusually acidic and has elevated levels of hydrogen ions (low pH). It is caused by the release of sulfur dioxide (SO2) and nitrogen oxides (NOx) into the atmosphere, which then reacts with water vapor to form sulfuric acid and nitric acid.
These acids can fall back to the ground as acid rain or other forms of precipitation and can cause harm to plants, animals, and infrastructure. Acid rain can also contribute to soil and water pollution and can have negative impacts on human health.
Acidic soil can also release toxic substances, such as aluminum, which can further damage plant roots and reduce plant growth. In addition, acid rain can damage plant foliage directly, leading to reduced photosynthesis and reduced yields.
So, acid rain can be a significant problem for plant species and crops, particularly those with a narrow soil pH range.

Explanation:
cows have a backbone so they are a vertebrate
cows have hair so they are mammals
and the are animals just like every other living thing
Three terms used to describe organisms such as cows are:
MammalsHerbivoresRuminantsWhat is an organism?An organism, especially a cow, is a living thing. An organism is a singular living being that exhibits characteristics of life, such as the ability to develop, reproduce, respond to stimuli, and preserve homeostasis. Mammalia, a class of multicellular organisms including cows, forms the animal kingdom. Cows are complex biological entities with specialized sensory and digestive systems that enable them to live and thrive in their environment.
The following three terms are used to describe cow-like creatures:
Cows are mammals, which are warm-blooded animals with hair or fur and the ability to feed their young with milk.
Herbivores: Cows are herbivores, which means they only eat plants and no animal products like meat or dairy.
Cows are included in the class of herbivorous mammals known as ruminants, which have a four-chambered stomach.

How did Watson and Crick learn about Chargoff's rules?
Answer:
Chargaff explained his findings and research to Watson and Crick at Cambridge.
Explanation:
Watson and Crick met Erwin Chargaff at Cambridge in 1952, where he explained his research and findings to them. His rule of parity, or 1:1 rule, stemmed from his discovery of guanine's equal ratio in pairing with cytosine.
Watson and Crick went in to use Chargaff's findings and the work of the researcher Rosalind Franklin as a basis for their work on DNA's double-helical structure.

If the sperm of a boa constrictor has 18 chromosomes, how many chromosomes will each skin cell of the snake have?
Answer:
18 chromosomes
Explanation:
If the sperm of a boa constrictor has 18 chromosomes, the number of chromosomes that each skin cell of the snake will have is 36 chromosomes.
What is meiosis?Meiosis is the process of gamete formation where each daughter cell or gamete contains half the number for f chromosomes as the parent cell.
According to this question, the sperm of a boa constrictor has 18 chromosomes. The sperm is a gamete formed as a result of meiosis.

Explain why it makes sense to use the word translation to describe protein synthesis and why it would not make sense to use the word translation to describe mRNA synthesis?
Answer:
The application of the word translation makes sense at the time of describing the synthesis of protein as the language of nucleic acids is transformed into the language of polypeptides by the phenomenon of translation. On the other hand, it will not be suitable to describe the synthesis of mRNA using the word translation as the nature of the biomolecule stays similar because both the DNA and the product of DNA, that is, mRNA are nucleic acids.
