Answer:
288 test tubes
Explanation:
Given,
Total chemistry classes = 3
The number of students in each classes = 24,
So, the total number of students in 3 classes = 3 × 24 = 72,
Also, each student to use 4 test tubes.
Therefore, the number of test tubes in 3 classes = 4 × 72 = 288,
Hence, 288 test tubes are needed in all for her classes.

C.White blood cells help in fighting against diseases and bacteria
An ant that is resistant to pesticide .
B)
A cactus that has no spines.
C)
A mouse that has learned to avoid mousetraps.
An example of an organism with a genetic variation that could improve survival chances over time would be an ant that is resistant to pesticides (Option A)
Genetic variation refers to differences in the genetic material (DNA) among individuals within a species. This can arise due to several mechanisms, including mutation, recombination, and genetic drift. Genetic variation provides the basis for evolution by natural selection, as it allows for populations to adapt to changing environments and helps to ensure the survival of the species over time.
Genetic variation can also play a role in disease resistance, as some individuals may carry genetic variations that protect them from certain diseases. Additionally, genetic variation can impact physical and behavioral traits, such as eye color, height, and intelligence.

True!
Desertanimals have less body fat than animals in cooler environments. In deserts thetemperature is high, but fat retains heat so it is not necessary for desertanimals to keep warm. Still, excess fat can be stored in the body of somedesert animals, for example, camels store fat inside their hump, and bisonsstore fat inside their neck. That fat can be used when food or it can bemetabolically be turned into metabolic water.

True

Answer:
They are levels of taxonomy. There are six Kingdoms currently in use: Animalia, Plantae, Fungi, Protista, Archaea, and Bacteria. Archaea and Bacteria fall under the Domain Prokaryota and the rest are under the Domain Eukaryota.
Explanation:
B. Genotype
C. Proteins
D. Carbohydrates
Answer: The correct answer is-
B. Genotype
Enzymes are primarily proteins that help in regulating the various metabolic reactions that occur inside the living organisms (such as digestion of protrins, fats, carbohydrates).
Genotype can be described as the genetic makeup of a life form that contains essential instruction (in the form of DNA sequence) for the synthesis of different proteins.
DNA (deoxyribonucleic acid) undergoes transcription to form mRNA (messenger RNA), which ultimately forms particular protein via a process called translation.
Thus, enzymes present in an organism are basically regulated by the genotype of the organism.
The genotype, or genetic makeup, of an organism regulates the enzymes present within it. This is because enzymes are proteins that are coded by an organism's genes. This sequence of genes composing the genotype informs which enzymes the organism is able to produce.
The genotype of an organism regulates the enzymes present in an organism. The genotype refers to the genetic makeup of an entity, which determines all the characteristics that entity can potentially have. In biology, it includes all the genes present in an organism, including those that are not expressed.
The enzymes are proteins that are coded for by these genes. Therefore, the enzymes present in an organism are regulated by its genotype, which dictates what proteins, including enzymes, are produced. Simply put, the specific sequence of genes in an organism's DNA makes up its genotype, and this directly informs which enzymes the organism can produce.
