how does tooth decay occur?
PLSSS HELP IF YOU TURLY KNOW THISS
Answer:
A. Stable
Explanation:
Because no one is leaving causing the population to decrease and no one is joining cause the population to gain people.
So your answer would be A. Stable
Answer:
The correct answer for this would be A
Explanation:
This is because if the growth rate of a population is zero then it means that it's unchanging which is another word for stable.

what is meristematic tissue? write its type? give one example of each.
Meristematic tissues, or simply meristems, are tissues in which the cells remain forever young and divide actively throughout the life of the plant. When a meristematic cell divides in two, the new cell that remains in the meristem is called an initial, the other the derivative.
Meristematic cells are generally small and cuboidal with large nuclei, small vacuoles, and thin walls. A plant has four kinds of meristems: the apical meristem and three kinds of lateral—vascular cambium, cork cambium, and intercalary meristem.
There are three primary meristems: the protoderm, which will become the epidermis; the ground meristem, which will form the ground tissues comprising parenchyma, collenchyma, and sclerenchyma cells; and the procambium, which will become the vascular tissues (xylem and phloem).
Answer:
The meristem is a type of tissue found in plants. It consists of undifferentiated cells capable of cell division. Cells in the meristem can develop into all the other tissues and organs that occur in plants. These cells continue to divide until a time when they get differentiated and then lose the ability to divide. Meristematic tissue and its types
There are three types of meristematic tissues: apical (at the tips), intercalary or basal (in the middle), and lateral (at the sides). At the meristem summit, there is a small group of slowly dividing cells, which is commonly called the central zone.
How does natural selection cause populations to evolve?
Organisms with favorable traits survive and produce fewer offspring
Organisms with favorable traits survive and produce more offspring
A species improves by letting only those individual organisms with desired traits reproduce
Humans select favorable or useful traits in animals for producing breeds with those traits.
Answer:
Organisms with favorable traits survive and produce more offspring
Explanation:
the first one doesn't make logical sense, the third one is wrong because that is sort of sectual (brainly wont let me write the correct term) selection (a mode of natural selection) and the fourth one is wrong because that's artificial selection (another mode of natural selection)

What are the two kinds of pyrimidines found in dna?.
Answer:
DNA are cytosine and thymine
Explanation:
in RNA, they are cytosine and uracil. Purines are larger than pyrimidines because they've a two-ring shape whilst pyrimidines simplest have a unmarried ring.
Answer:
Cytosine and Thymine
Explanation:
Of the four DNA bases, (C, T, A and G), C and T are pyrimidines. The way I remember it is, C, U (which is only in RNA) and T are "pyrimidines", which has more than 3 syllables, hence there are 3 bases in this category, as compared to purines which only contain 2 (A and G).

During transcription only the "coding" strand of DNA is used. Why is it important which of
the strands is used?
Answer:
During transcription, the coding strand of DNA serves as a template for synthesis of a complementary RNA molecule. The sequence of the RNA molecule is determined by complementary-base pairing so that the RNA is a complementary transcript (copy) of the coding strand of DNA.
Explanation:
What is transcription why is it important? The goal of transcription is to make a RNA copy of a gene's DNA sequence. For a protein-coding gene, the RNA copy, or transcript, carries the information needed to build a polypeptide (protein or protein subunit). One strand, the template strand, serves as a template for synthesis.
The coding strand contains codons, which are the nucleotide triplets which specify a unique amino acid in the polypeptide chain. These codons collectively make the genetic code, which is a universal feature in almost all the living forms on the earth. Coding strand during the transcription is shown in figure 2.
Answer:
it important because u needed to know the type of strand that are being use in dna to in order to have proper body.

b. Soil that eroded from the river banks mixes into the water and clouds it.
c. Acidic glacial ice weathers limestone into a chalky powder, which clouds the water.
d. Millions of microorganisms living in the ice stay suspended in the river water.
Answer:
Either c or d
Explanation:
Apologies if I'm incorrect, I'm no expert, but let me know if it's wrong I'll take it down.
how is pH of the water will increase
Pure water has a pH level of 7, which means it is neutral on the pH scale. If you want to increase the pH of water, you must add an alkaline substance to it. The pH scale ranges from 0 to 14, with anything above 7 being alkaline, and anything below 7 being acidic.

Describe the three properties of language systems.
Answer:
This means that individuals use sounds and written symbols to represent objects, actions, events, and ideas. The second property of a language system is that language is generative. This means that a small number of symbols can be combined in an endless variety of ways to create many messages. The third property of a language system is that language is structured. This means that specific rules govern the way words are arranged and the way sentences are made so that communication is effective. B. F. Skinner claimed that the nativist theory is the accurate theory to explain the process of language development.
