Answer:
Explanation:
Polydactyly is having six fingers as against the 5 fingers. The Sixth fingers grows out like normal finger giving an additional finger.
Polydactyly is usually expressed in dominant form, when an individual is recessive for the traits such individual have 5 fingers.
In human, the rate of occurrence for polydactyly is low this is because it is a rare occurrence and it takes two individual who have the allele to produce an individual who will be dominant of the allele. The recessive allele is what is common to human.

Movement of the particles across the membrane stops when the concentration gradient no longer exists, the particles will continue to diffuse due to random motion
Answer:
Once the concentration gradient no longer exists, particles will continue to diffuse due to random motion.
Explanation:
When there is a permeable membrane between two solutions with different concentrations, the concentration gradient will go from the compartment with more particles to the one with fewer particles to valance the concentrations on both sides of the membrane. Once the concentrations are equal, particles will still randomly move from one side to the other, but the number of particles that move to one side is almost the same as the number of particles that move to the other, so there is still valance and the same concentration in both sides.

which is true regarding the process of meiosis I?
A) chromosome Number is reduced from diploid to haploid
B) sister chromatids in a cell undergoing are always identical
C) Most homologue pairs do not have any crossovers during prophase I
D) sister chromatids separate to opposite ends of the cell
Answer: The correct option is A (chromosome Number is reduced from diploid to haploid)
Explanation:
In sexual reproduction, offspring are produced by fusion of two different sex cells which usually come from two different parents. These sex cells are know as gametes.
Meiosis is a type of cell division that gives rise to gametes in which the chromosome number is halved. Thus, the gamete cell is said to contain a haploid number (n) of chromosomes.
A diploid cell has two sets of chromosomes: one from the male parent and the other from the female parent. When a diploid cell undergoes meiosis the following occurs:
--> the chromosomes replicate once and
--> the nucleus and cell duplicate ( divide equally) twice.
As a result, the diploid parent cell gives rise to four haploid gamete cells. Therefore the statement "chromosome Number is reduced from diploid to haploid ' is true concerning meiosis I.
How does camouflage help an organism survive?

O
D. the rise of dinosaurs and other reptiles
Answer:
oh yeah daddy
mink ,
Explanation:
Answer:
B
Explanation:
The Cenozoic era was known to be called the age of mammals, because the largest land animals have been mammals during that time. Meaning Mammals that swim would also be living during that time with land mammals.

PLEASE I NEED HELP ASAP!! WILL GIVE BRAINLIEST AND 100 POINTS!!! When you cross two heterozygous organisms, what is the probability that the offspring will show the dominant phenotype? (HINT: You may want to draw a Punnett Square on a separate piece of paper to help.)
A. 100
B. 75
C. 50
D. 25
E. 0
Answer
75% chance
Explanation:
The dominant and recessive are the terms used to explain the phenotypic traits and genetic makeup of an organism. The cross between a heterozygous species will result in a 75% chance of the species expressing a dominant phenotype.
The correct answer is:
Option B. 75%
The heterozygous condition refers to the one dominant and one recessive allele, whereas purebred is the condition in which both alleles are either recessive or dominant.
The dominant alleles are always expressed in purebred and heterozygous conditions.
The recessive alleles are expressed in purebred conditions only.
In the given attachment, consider the cross between round shaped-seeds in heterozygous conditions.
Thus, the chance of progeny will have round-shaped seeds is 75%.

What are two genotypes that could produce a dominant phenotype?
Answer:
A homo-zygous dominant genotype and a heterozygous genotype
Explanation:
A homo-zygous dominant genotype refers to a genotype that contains two copies of the dominant gene variant, i.e., two dominant alleles at its locus, thereby individuals carrying this genotype will show a dominant phenotype. Moreover, a heterozygous genotype is a genotype that contains both dominant and recessive alleles at its locus. In a heterozygous genotype, the dominant allele is always expressed and masks the recessive allele, thereby showing a dominant phenotype.

Name the hormone released when the blood glucose concentration is too low
Explanation:
Glucagon
vbbxfj be vcxxxcghjhhg
Answer:
Glucagon is released to stop blood sugar levels dropping too low (hypoglycaemia), while insulin is released to stop blood sugar levels rising too high (hyperglycaemia). The release of glucagon is stimulated by low blood glucose, protein-rich meals and adrenaline (another important hormone for combating low glucose).

If 30% of a DNA sample is composed of thymine nucleotides, what percentage of the DNA sample would be composed of cytosine nucleotides?
Answer:
20%
Explanation:
Pairing do occur between a purine and a pyrimidine base or a pyrimidine and a purine base where Adenine pairs with Thymine and Guanine pairs with Cytosine.
DNA(deoxyribonucliec acid) sample is usually compose of 100% nucleotide base,
Since 30% of the sample section is compose of thymine then Adenine the base pair will also be 30% this is because adenine will always pair with thymine and each will occur in equal quantity. Together, adenine and thymine compose 60% of the segment.
While the remaining 40% of the section is composed of guanine and cytosine pairs and since the two bases will be equal in quantity, 20% of the DNA section will be cytosine nucleotide.
