Answer:
There will be no children without dimple and have only children with dimples.
Explanation:
Dimples in humans are characteristic that is influenced by the dominant allele of a gene which is represented by D and its recessive allele is d. So the DD which is pure and Dd which is a heterozygous condition for this characteristic and represents offspring or individual with the dimples. The pure condition of recessive alleles dd represents an individual without dimples.
Dd crosses with DD:
gametes will be D and d, and D and D.
D d
D DD Dd
D DD Dd
There are only two types of genotypes are produced that are:
DD - individual with dimples
Dd - individual with dimples
Thus, there will be no children without dimple and have only children with dimples.

WHAT'S THE DIFFERENCE BETWEEN INCOMPLETE DOMWANCE AND CO-ODOMINANCE ? GIVE EXAMPLES OF THE BOTH INCOMPLETE AND
CO-ODOMINACE. USE THE PUNNET SQUARE TO SUPPORT YOUR ANSWER
Answer/Explanation:
Incomplete dominance is when one allele is not entirely dominant over the other, resulting in an intermediate phenotype. Example could be in flower colour. F is the allele for red flowers, f is the allele for white flowers. Let's cross a red flower (FF) with a white flower (ff):
F F
f Ff Ff
f Ff Ff
100% of the offspring are Ff. F is in completely dominant to f, so all the offspring have an intermediate phenotype - all the flowers are pink.
Co-dominance is when neither allele is dominant and both alleles are expressed equally. An example is in human blood types. A and B alleles are both dominant to the O allele, but co-dominant to each other. Therefore, if an individual who is AO has children with an individual who is BO:
A O
B AB BO
O AO OO
The individual would either be blood type O (OO), blood type A (AO), blood type B (BO) or blood type AB (AB)
describe the chromosomal difference between sex cells and a zygote (fertilized egg)/ body cells
Answer:
The main difference between sex cells and zygote is the chromosomal charge, where the sex cells have half of the chromosomes haploid and the zygote has the full load, is diploid, as well as the body cells.
Explanation:
Ploidy is based on the number of chromosomes found in a cell:
If the cell contains the full charge of chromosomes it is called a diploid (2n). This occurs in body cells and in the zygote. When a cell contains half the charge of chromosomes, it is called haploid (n), and it only occurs in gametes or sex cells.The reason for this difference is that the gametes go through a process of reductional division, called meiosis. They are haploid because when the gametes of the parents unite —during fertilization— they give rise to a haploid cell, the zygote.

How might a reduction in species diversity affect the other three components of biodiversity?
Answer:
if the species diversity in an ecosystem or on the Earth gets reduced, it will affect the balance biodiversity and its other components. The three components of biodiversity are: ecosystem, species, and genetic diversity.
Biodiversity is defined as the variety of life forms existing in different ecosystems on planet Earth.
The three components of biodiversity are:
genetic diversity, species diversity, ecosystem diversity.If there is a reduction in the species diversity, there will be an imbalance in biodiversity, which is integrated, where each living being has an essential role in the maintenance and sustainability of the planet.
Biota reduction will therefore directly impact the ecosystem and will alter the correct flow of environmental balance.
It is possible to see through history, that many species of animals were extinct by human exploitation and this action cannot be reversed.
Therefore, it is essential to make each individual aware of the importance of developing sustainability for the preservation of nature and the quality of life of current and future generations.

What is rock?Rock has defined as when mineral grains are combined in the solid form and later grow or take shape of cemented form has been known as rocks.The rocks are made up of the more than one mineral and the size of some rocks are the small or big it depends upon their constituents. Rocks has been divided on the basis of their formation by Geologists.There are mainly three kinds of rock and these are metamorphic, igneous, and sedimentary. The most durable substance has been the stone.
Sedimentary rocks are generally made up from directly heat and these are formed when deposition or accumulation of particles that are organic or minerals at the surface of Earth, later followed by the process of cementation. The main feature of sedimentary rock is that they are formed in multiple layers.The rocks are made up of more than one mineral and the size of some rocks are small or big it depends upon their constituents.
Therefore, The sentence that describes the heterogeneous mixture is beach sand, a substance that can contain rocks, shells, metals and other substances distributed unevenly throughout. Thus, option C is correct.

Answer:
Affinity chromatography is a technique based on specific binding interactions
Explanation:
Affinity chromatography is a technique used to separate and identify macromolecules by their specific binding biological interactions. This technique enables the identification of macromolecules that establish specific types of binding interactions including, among others, antigens and antibodies, receptors and ligands, etc. Affinity chromatography is the most widely used technique for antibody purification because this method has high selectivity and enables to concentrate the target molecule in a single step. Antibody fragments such as single-chain variable fragments (scFV) can be purified by affinity chromatography when they are covalently immobilized to a solid support (for example, agarose beads).

Both hexokinase IV and hexokinase I phosphorylate glucose at carbon-6. What properties of hexokinase IV make it important for maintaining stable blood sugar levels
I am going to explain the properties of hexokinase IV and it's properties that make it important for the maintainance of stable blood sugar level.
Hexokinase as well as Hexokinase IV all phosphorylate the glucose at C-6, Because Hexokinase IV has a low affinity with glucose and it is expressed in the liver,so it does have a way of maintaining blood sugar level.
When the blood glucose is low generally,it isn't saturated or working,but when the blood glucose gets high,it becomes transactivated and the activity of glucose 6 phosphatase results in low blood glucose.
Therefore,the most important activity of
Hexokinase IV is the regulation of blood glucose levels.
