Answer:
4/16 (i.e. 25%)
Explanation:
A dihybrid cross is a cross between two organisms/lines/genes that are hybrids (i.e., heterozygous) for two different traits. In a standard dihybrid cross, there is a relation of complete dominance for both <em>loci</em>, i.e., there are two alleles that are completely dominant and thus mask the effects of the corresponding recessive traits. In a dihybrid cross involving two different genes that assort independently into gametes during meiosis, with dominant alleles "A" and "B" and recessive alleles "a" and "b", respectively, the expected phenotypic ratio will be 9:3:3:1 (ie. 9/16 A_B_, 3/16 A_bb, 3/16 aaB_ and 1/16 aabb), while the expected genotypic ratio of double heterozygous "AaBb" individuals will be 4/16, i.e. 25%.
Representation:
P generation >> AaBb (father) X AaBb (mother)
Gametes (for both parents) >> 1/4 AB; 1/4 Ab; 1/4 aB; 1/4 ab
F1 generation >> 1/16 AABB; 2/16 AABb; 2/16 AaBB; 4/16 AaBb; 1/16 AAbb; 2/16 Aabb; 1/16 aaBB; 2/16 aaBb; 1/16 aabb
Answer:
Fishes are typically divided into three groups: superclass Agnatha (jawless fishes), class Chondrichthyes (cartilaginous fishes), and superclass Osteichthyes (bony fishes). The latter two groups are included within the infraphylum Gnathostomata, a category containing all jawed vertebrates.
Smooth muscle, a type of tissue that allows for constriction or dilation, makes up the blood vessel walls. The absence of striations (stripes), which are present in both skeletal and cardiac muscles, gives smooth muscle its name.
Only smooth muscle cells are found in blood arteries. The tunica media houses these muscle cells, elastic fibres, and connective tissue. Even though vessels only have smooth muscles, skeletal muscle contractions are crucial for the venous system's ability to transport blood from the periphery to the heart.
The autonomic nervous system regulates the smooth muscle found in the walls of hollow internal organs like blood vessels, the gastrointestinal tract, the bladder, and the uterus. Since smooth muscle cannot be consciously controlled, it behaves spontaneously.

The answer to the question you asked is ..... Microfilaments.
Answer:
Legal
Explanation:
Legal risk is basically a type of risk where the source or consequence is legal in nature. It is basically a risk that has a legal issue as its source and a legal issue is a set of facts that are assessed under a set of legal norms.
Hence, Diabetic Daily Inc., based in the United States, hesitates to enter into a joint venture with Azpak Limited, a Sri Lankan company, due to inadequate protection of intellectual property rights. Diabetic Daily Inc. is trying to avoid <u>legal</u> type of risk.
