Which type of feather gives the bird its color?
down
barb
contour
flight
Answers
it contour
I hope it work
Contour type of feather gives the bird its color. Therefore, the correct option is C.
The outer feathers that give a bird its color and general appearance are known as contour feathers. The barbs on the branches that make up the central shaft of these feathers join to form a strong, streamlined structure. The barbs have their own little branches, known as barbules, which contain pigments that help give the bird its color.
The diverse colors and patterns seen on many bird species are determined by the arrangement and color of pigments in the barbules of contour feathers. Therefore, contour feathers are important in determining a bird's color.
Therefore, the correct option is C.

In a plant species, the allele for dark green leaves (D) is dominant over the allele for light green leaves (d). A plant with Genotype (Dd) is crossed with a plant with genotype (did). What percentage of the offspring are expected to be hybrid for the leaf color trait. A 0% B 25%. C.50%. D 75%
Answers
So, as we set the punnet square. We get (2)Dd and (2)dd. So 100/2 = 50%.
Correct choice - C 50%.
The percentage of the offspring that is expected to be hybrid for the leaf color trait is 50%. The correct option is C.
What are alleles?The trait is caused by a pair of two alleles on the chromosome, and there are two possible outcomes. The dominant allele, which is typically written in capital letters and will control the organism's phenotype even in the presence of the other allele, is the one that has the ability to silence the other allele.
It is used in biology to refer to inherited traits that do not manifest in the phenotype of the individual who possesses them but may do so in their offspring.
Recessive alleles, which are only expressed when they are homozygous, are this other type of allele. Both heterozygous and homozygous genotypes exhibit the dominant allele.
Dd is crossed by dd.
100 / 2 = 50%.
Therefore, the correct option is C.

As a frog develops from a tadpole into an adult frog, it goes through changes that are signaled by hormones within the body. Which best describes the role hormones play in changing a tadpole to a frog?
Answers
Answer: In amphibians, metamorphosis is generally associated with the changes that prepare an aquatic organism for a primarily terrestrial existence In (frogs and toads), the metamorphic changes are more dramatic, and almost every organ is subject to modification Regressive changes include the loss of the tadpole's teeth and internal gills, as well as the destruction of the tail. At the same time, constructive processes such as limb development are also evident. The means of locomotion changes as the paddle tail recedes while the hind limbs and forelimbs develop. The tadpole's cartilaginous skull is replaced by the predominantly bony skull of the frog. The teeth used for tearing pond plants disappear as the mouth and jaw take a new shape, and the tongue muscle develops. Meanwhile, the large intestine characteristic of herbivores shortens to suit the more carnivorous diet of the adult frog. The gills regress, and the gill arches degenerate. The lungs enlarge, and muscles and cartilage develop for pumping air in and out of the lungs. The sensory apparatus changes, too, as the lateral line system of the tadpole degenerates, and the eye and ear undergo further differentiation The middle ear develops, as does the tympanic membrane characteristic of frog and toad outer ears. In the eye, both ingratiating membranes and eyelids emerge.

In "gastrulation" cells begin to differentiate. They form different types of tissues so they can accomplish different purposes in the body.
True or False?
Answers
Answer:
The statement that says that In "gastrulation" cells begin to differentiate and they form different types of tissues so that they can accomplish different purposes in the body, is true.
Explanation:
Gastrulation involves a process of cell division, migration and differentiation, being one of the stages of embryonic development.
Cell differentiation and migration in gastrulation leads to the formation of germ layers, which are responsible for forming different tissues and fulfilling different functions in the body:
The outermost lamina is called the ectoderm, which can give rise to nerve tissue and part of the skin tissue. The mesoderm is the middle lamina, and from it vascular, bone, muscle, and joint tissue can develop, as well as tissues of excretory and reproductive organs. Endoderm corresponds to the internal lamina, forming in great part the mucous membrane of the organs of the digestive system.It is true, then, that In gastrulation cells begin to differentiate and form different types of tissues so they can accomplish different purposes in the body.
