and a "chest cold" of 2 months' duration. She was advised to quit smoking, a major cause of
lung irritation. These symptoms were caused in part by the obstruction of groups of alveoli

Answers

Answer 1

The small cell extensions that beat to create an up-ward current are called microvilli.

What are microvilli?

Microvilli are small extensions which are found on the surface of the alveoli of the lungs.

The microvilli play an important role in the lungs as the help to remove particles and mucus that may obstruct the lungs as a result of the upward current they create in the lungs from their beating motion.

Therefore, the paralyzed small cell extensions that beat to create an up-ward current are called microvilli.

Explanation:

The pH value is a unit of measure which describes the degree of acidity or alkalinity of an aqueous solution. In other words, pH demonstrates the quantitative information of the activity of an acid or base based on hydrogen ion concentration.

The mathematically formal definition of pH is the negative logarithm of hydrogen ion concentration:

                                             [tex]pH \ \ = \ \ -\log_{10}\left[H^{+}\right][/tex].

Hence, if the concentration of [tex]\text{H}^{+}[/tex] ions in a solution is [tex]1.0 \ \times \ {10}^{-7} \ \text{M}[/tex],

                                           [tex]pH \ = \ -\log_{10}\displaystyle{\left(1 \ \times \ {10}^{-7}\right)} \\ \\ pH \ = \ -\log_{10}\displaystyle{\left(1\right) \ - \ \log_{10}\left({10}^{-7}\right)} \\ \\ pH \ = \ 0 \ - \ \left(-7\right) \\ \\ pH \ = \ 7[/tex].

Define Evolution and Natural Selection

Answers

Answer:

Evolution may be defined as any net directional change or any cumulative change in the characteristics of organisms or populations over many generations—in other words, descent with modification… It explicitly includes the origin as well as the spread of alleles, variants, trait values, or character states.

Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways. This variation means that some individuals have traits better suited to the environment than others

the 5’ end of the dna molecule is considered ____, while the 3’ end of the dna molecule is considered the _____

Answers

Five prime and three prime.. if it’s correct pls let me know

The 5’ end of the dna molecule is considered five prime, while the 3’ end of the dna molecule is considered the three prime.

Thus, The backbones of DNA's two long polymers of basic units, known as nucleotides, are comprised of sugars and phosphate groups that are connected by ester bonds.

These two strands are anti-parallel because they move in the opposite directions of one another. Each sugar has one of four different nucleobases (bases) molecules attached to it.

The genetic code is made up of the order of these bases, and it subsequently dictates the order of the amino acids in proteins. The 5′ (five prime) and 3′ (three prime) ends of DNA strands are referred to as the ends.

Thus, The 5’ end of the dna molecule is considered five prime, while the 3’ end of the dna molecule is considered the three prime.

Answers

Beau’s coat hair changed from straight to curly because of Denaturation occurs.

What is happening at the molecular level to proteins?

When a chemical relaxer and heat are applied to curly hair, the protein present inside your hair gets denatured. Due to this denaturation of protein in the hair, the hair is soft and flexible which can be converted into any direction and different styles can be done. If a chemical perm or relaxer is applied to straight hairs, it also denatures the protein and make the hair curly.

The stages of meiosis 1 and meiosis 2 is discussed below:

What is meiosis?

Eukaryotic cells (plants, animals, and fungi) reproduce sexually through a process called meiosis. Chromosome reduction is the process by which haploid cells are created from diploid cells, which are cells with two complete and identical sets of chromosomes.

The number of chromosomes in each cell is halved during meiosis I, which starts with one diploid parent cell and ends with two haploid daughter cells.

Maintaining the number of chromosomes in each cell, meiosis II begins with two haploid parent cells and finishes with four haploid daughter cells. Before meiosis II, homologous pairs of cells divide into chromosomes while in meiosis I.

These chromosomes are further divided into sister chromatids during meiosis II. Meiosis II does not include genetic material crossing across or recombining between chromosomal pairs, whereas meiosis I do.

This happen in the  prophase contains five subphases and is lengthy and complex during meiosis I. The equatorial plane in meiosis II is aligned 90 degrees differently than in meiosis.

Therefore interphase1, prophase 1, metaphase 1, anaphase, and telophase 1 are the stages of meiosis 1 and prophase Il, metaphase II, anaphase II, and telophase Il in meiosis 2.

There were more substrate molecules to bond with the active site of the catalase enzyme as the substrate concentration increased.
