when do you use cpctc in a proof
The two triangles must first be shown to be congruent using one of the triangle congruence criteria before CPCTC may be established. Consider the triangles ABC and CDE, for instance, where BC = CD and AC = CD are specified.
Corresponding Parts of Congruent Triangles are Congruent abbreviated as CPCTC. According to the CPCTC theorem, every corresponding component of one triangle is congruent to the other when two triangles are congruent. This indicates that when two or more triangles are congruent, the accompanying sides and angles are likewise congruent or equivalent in size. If two triangles are precisely the same size and shape, they are said to be congruent. Three of the sides and the angles of two congruent triangles are equal to one another. When a triangle's three sides correspond to those of another triangle, they are at the same location. According to corresponding angles, the three angles of one triangle are located in the same area as those of the other triangle.

What are recessive alleles?Recessive alleles are alleles that are encoded by recessive genes.
Recessive alleles do not appear phenotypically except when the dominant allele is absent. Hence, recessive alleles only appear in an offspring that is hom0zygous for the given recessive allele.
Hom0zygous means that the two copies of the allele are the same for that trait, either they are hom0zygous dominant or hom0zygous recessive.

what is the definition of epistasis 1 point
The state known as "epistasis" occurs when the expression of one or more additional genes alters (e.g., masks, inhibits, or suppresses) the expression of a specific gene.
Epistasis refers to the interaction of genes that influences a phenotype. One phenotype with different properties can be determined by a conditional relationship between two genes. Genes can either work together to form a new trait or can hide one another so that only one is identified as "dominant." When it comes to gene pathways, this is typically seen since the presence or absence of one gene product directly impacts the expression of another gene within the pathway. This is also known as allelic complementation or interallelic complementation.
So, the interaction of genes with phenotype is what we mean when we say "epistasis."

What is CBR?The crude birth rate is the number of live births per 1,000 of the population at the midyear census. long explanation The crude birth rate is the number of live births per 1,000 of the expected population at the midyear mark.
Given data;
CBR= 2.9%, Immigration = 1%,
CDR = 2.1%, Emigration = 1%

Shelley was married once before and did have a male child with sickle cell anemia. She does not have the disease herself. (sickle cell anemia is an autosomal, recessive disease)
What is the probability that their unborn baby will have sickle cell anemia?
The probability that their unborn baby will have sickle cell anemia is 1/4 or 25%.
Genetic probabilitySickle cell is an autosomal recessive disease. This means that both males and females have an equal chance of having the disease. They can also be carriers or not affected equally.
Martin does not have the disease but has a sibling with sickle cell anemia. It means his parents are each a carrier of the disease. Assuming the allele for sickle cell is s.
Ss x Ss
SS Ss Ss ss
Probability of unaffected = 1/4
Probability of being a carrier = 1/2
Probability of being affected = 1/4
Shelley was once married and had a male child with sickle cell. Since she does not have the disease herself, it means she's a carrier (Ss).
Assuming Martin is unaffected:
SS x Ss
SS Ss SS Ss
Probability of their unborn having sickle cell = 0
Assuming Martin is a carrier:
Ss x Ss
SS Ss Ss ss
The probability of their unborn having sickle cell = 1/4
Thus, the probability that their unborn baby will have sickle cell anemia is either 0 or 25%

What causes red hair?
Red hair is a recessive hereditary feature induced by a sequence of mutations in the MC1R gene on chromosome 16. Because red hair is a recessive feature, it must be inherited from both parents.

Based on the sucrose uptake model, experimental treatments that increase the rate of sucrose transport into cells is decreasing extracellular pH.
Is sucrose used in transportation? Sucrose is synthesized in the cytoplasm, translocated from cell to cell across the plasmodesmata or membranes, and either compartmentalized or transported to the apoplasm for uptake by neighboring cells. Sucrose, a relatively large polar compound, requires proteins to facilitate efficient membrane trafficking.Sucrose reaches the sieve tube via plasmodesmata and allows cell-to-cell diffusion in species such as gourd. It is converted into larger molecules (RFOs) by the sequential addition of galactosyl residues in modified companion cells (CCs) called intermediate cells.In plants, sucrose is the major transport form of photoassimilated carbon, the source of the carbon skeleton, and the energy source for non-photosynthetic plant organs (sink organs). As a molecule to be transported over distance, sucrose must pass through a series of membranes.Can cells take up sucrose?Dietary carbohydrates of particular importance include starches and disaccharides such as lactose and sucrose.
