Answer: frig metamorphosis is complete

Explanation:

This is because in complete metamorphosis, frog develop from egg to adults. Metamorphosis refers to change of shape and growth in different stages of animals life cycle.

Frog mate in the rainy season.

There are four stages of frog metamorphosis and they are;

1 Egg : the female mate with the male and the male fertilizes the egg. The female releases the fertilized egg inside water , they egg are jelly like or cover with jelly covering.

2. Tadpole: the egg then hatched into tadpoles. The tadpoles live in water, it does not have lungs and limbs. It move like fish and uses gills to breathe. At this stage it starts developing hind limbs and later lungs. It has long tail

3. Froglet : At this stage, the lungs and the front legs develop. It floats above the water to breathe. The tail become shorter and it uses nutrients stored in the tail to feed or survive.

4. Adult : this is the final stage, the young frog leave water and start live on land, it's tail disappear completely and it's start feeding on insects.

Show a diagram of how ions are formed when a sodium atom comes into close

Firdavs [7]

Answer:

The diagram is attached below.

Explanation:

when sodium and chlorine comes close together they form anion and cation. The compound formed is called sodium chloride.

Both atoms bonded together through ionic bond.

Ionic bond:

It is the bond which is formed by the transfer of electron from one atom to the atom of another element.

Both bonded atoms have very large electronegativity difference. The atom with large electronegativity value accept the electron from other with smaller value of electronegativity.

For example:

Sodium chloride is ionic compound. The electronegativity of chlorine is 3.16 and for sodium is 0.93. There is large difference is present. That's why electron from sodium is transfer to the chlorine. Sodium becomes positive and chlorine becomes negative ion.

What type of mutation has occurred in the dna of people with sickle cell anemia? (look back, if you need to, to see what causes

strojnjashka [21]

People with two copies of the sickle cell gene have the disease. People who carry only one copy of the sickle cell gene do not have the disease, but may pass the gene on to their children. Abnormal hemoglobin, called hemoglobin S, causes sickle cell disease (SCD). The problem in hemoglobin S is caused by a small defect in the gene that directs the production of the beta globin part of hemoglobin. This small defect in the beta globin gene causes a problem in the beta globin part of hemoglobin, changing the way that hemoglobin works.

Varieties of plants in which self-fertilization produces offspring that are identical to the parents are referred to as monohybr

Mademuasel [1]

Varieties of plants in which self-fertilization produces offspring that are identical to the parents are referred to as true-breeding. In this process the parents will pass down specific phenotypic trait of their offspring. True bred organisms will have pure genotype (genetic make up of an organism) and will therefore produce certain phenotype.
