Answer:

Similarities Between Them

Archaea and bacteria are both prokaryotes, meaning they do not have a nucleus and lack membrane-bound organelles. They are tiny, single-cell organisms which cannot be seen by the naked human eye called microbes.

Dmitry [639]

The mesoderm is one of the germ layers present in an embryo and it develops primarily into muscles and organs. The radioactive marker would therefore be visible in the adult organism's cardiac muscle cells, smooth muscle cells, skeletal muscle cells, red blood cells and many other such specialized cells.

What are the parts of animal and find their function.

REY [17]

Answer:

<h2>⚪parts of animals are:</h2>

tail,claws,wings, beak ,fur , fins, she'll, feather.

<h2>⚪function of animal parts</h2>

Many land animals use their tails to brush away flies and other biting insects. Some species, including cats and kangaroos, use their tails for balance; and some, such as monkeys and opossums, have what are known as prehensile tails, which are adapted to allow them to grasp tree branches.

<h3>claws:</h3>

Claws may be adapted for scratching, clutching, digging, or climbing. By analogy, the appendages of other lower animals are frequently called claws. The claw's shape is ordinarily suited to the food-getting habit of the animal.

Wing, in zoology, one of the paired structures by means of which certain animals propel themselves in the air. ... The primary flight feathers on the distal portion of the wing create most of the propelling force in flight, while on the less mobile upper wing the secondaries provide the greater portion of the lift.

All birds have one beak. But it has evolved differently in each species to improve its functions in response to its environment. These functions include feeding themselves and their young, defending themselves, grooming their feathers, mating, regulating their body temperature or building nests.

Fur is a thick growth of hair that covers the skin of many different animals, particularly mammals. ... The fur of mammals has many uses: protection, sensory purposes, waterproofing, and camouflaging, with the primary usage being thermoregulation.

Fins typically function as foils that produce lift or thrust, or provide the ability to steer or stabilize motion while traveling in water, air, or other fluids. ... Fish, and other aquatic animals such as cetaceans, actively propel and steer themselves with pectoral and tail fins

<h3>shell:</h3>

Turtles and tortoises are some of the best-known shell-dwelling creatures. The difference between them is that tortoises live on land while turtles prefer the water

<h3>feather:</h3>

Feather Function: What do feathers do? Each feather on a bird's body is a finely tuned structure that serves an important role in the bird's activities. Feathers allow birds to fly, but they also help them show off, blend in, stay warm, and keep dry.

In fruit flies, straight wings are dominant and curly wings are recessive. What will the generations look like? Assume that Mend

anzhelika [568]

Answer:

The P generation has straight wings and curly wings.

The F1 generation has all straight wings.

The F2 generation has straight wings and curly wings.

Explanation:

This question involves a single gene coding for wing shape in fruit flies. The allele for straight wings (S) is dominant over the allele for curly wings (s). This means that allele "S" will mask the phenotypic expression of allele "s" in a heterozygous state.

According to the question, the cross follows all Mendel's method of crossing two true breeding parents with opposite traits. Hence, the parent generation (P generation) will be between a truebreeding straight wings parent (SS) and a truebreeding curly wings parent (ss). (See attached image for full cross).

Since the straight wing allele (S) is dominant, all the F1 offsprings will possess straight wings with the genotype: Ss, which is heterozygous.

If this F1 offsprings are self-crossed i.e. Ss × Ss, four possible offsprings in the phenotypic ratio 3 straight wings : 1 curly wing will be produced in the F2 generation. The offsprings will possess the following genotypes: SS, Ss, Ss, and ss.

Offsprings SS, Ss, and Ss will all be phenotypically straight-winged

Offsprings ss will be phenotypically curly-winged.

In overall, this means that P generation has both straight and curly wings (SS and ss), F1 generation has only straight wings (Ss), F2 generation has both straight and curly wings (SS, Ss and ss).

Based on the information above, which of the following is true about the process in which the genetic code stored in DNA is used

DanielleElmas [232]

Answer:

D.This process requires the interaction of several different cellular structures,

Explanation:

We don't have the information above. However, this process occurs in all cells, and it requires energy. Semi-conservative refers to the fact that, during DNA replication, each new molecule of DNA is made up of one strand of the original DNA molecule and one strand of a new molecule.

The synthesis of proteins from the information in an mRNA molecule does require several structures in the cell, including the nucleus, ribosomes, endoplasmic reticulum and Golgi apparatus.
