Answer;

- Cardiac tissue

Explanation;

-Gap junctions are a specialized intercellular connection between a multitude of animal cell-types. They allow the exchange of ions, second messengers, and small metabolites between adjacent cells and are formed by two unrelated protein families, the pannexins and connexins.

-Gap junctions are particularly important in cardiac muscle: the signal to contract is passed efficiently through gap junctions, allowing the heart muscle cells to contract in unison.

The tissue to have cells with the greatest number of gap junctions is the cardiac tissue.

Cardiac tissue refers to the involuntary, striated tissue present in the heart. It is made up of individual heart muscle cells called the cardiomyocytes. They are joined together by intercalated discs which contain the gap junctions. Gap junctions are the specialized intercellular connections which link the cytoplasm of two cells. Gap junctions play a crucial role in regulating the velocity and safe impulse propagation in the heart. They are abundantly found in the cardiac tissue helping in direct transmission of the deplolarizing current from cell to cell across the chambers of the heart. The signals for contraction of the cardiac muscle is passed through these gap junctions.

Bad White [126]

<u>Answer:</u>

"G-Factor" is associated with a theory of intelligence proposing a singular underlying aptitude or intellectual competence of intelligence.

<u>Explanation:</u>

An English psychologist Charles Edward Spearman was highlighted for his work in statistics as a pioneer of factor analysis. He speculated that humans had "G-Factor" i.e general intelligence (established in 1904 by Charles Spearman) from very early in the measurement of intelligence in history.

G-factor is a singular underlying aptitude or intellectual ability in many fields which include verbal, reasoning and spatial abilities. The general intelligence tests the level of expertise in applying logic to solve work-related problems by measuring the basic cognitive abilities regarding specific skills like memorization, arithmetic and common global knowledge.

In pea plants, purple flowers are dominant to white flowers, and the purple and white alleles are represented with P and p, resp
amm1812

Answer: 75% of the plants are purple and 25% are white. The phenotypic ratio can be expressed as 3:1.

Explanation:

Heterozygous means that its genotype has two distinct alleles, i.e. a dominant and a recessive one. So the genotype of the plants is Pp, and each plant has two alleles since<u> they are diploid organisms, which have two copies of each gene. </u>

<u>Each plant produces gametes, which are haploids cells. That is, they only have one copy of each gene (one allele)</u>. So, the gametes produced by Pp have a P or p genotype.  During fertilization, the maternal and paternal gamete are fused to form a diploid zygote where their genotype will have one allele from the father and one from the mother.

By making this monohybrid cross, we cross the gametes of each parent in the punnett square (see picture)

In the offspring, we see one PP genotype (homozygous dominant), two Pp genotypes (heterozygous) and one pp genotype (homozygous recessive). <u>Since we know the P allele is dominant and it codes for purple color, a genotype only needs one P allele to express that phenotype</u>. So Pp and PP organisms are purple, and only pp is white. That means 75% of the plants are purple and 25% are white. The phenotypic ratio can be expressed as 3:1.

Mitosis

<span>Mitosis and meiosis are simply cell division processes that occurs differently, they're characteristically divergent from each other according to their function and structure.

Mitosis is the cell division that happens in all cells in the human body except sperm and egg cells. They produce diploid cells. </span>
