The probability of progenies to have red flower is 50%.
<h3><u>Explanation:</u></h3>
The phenomenon where the two pure alleles of a particular character present in an individual gives a mixed appearance is called incomplete dominance, where the dominant character cannot fully mask the presence of a recessive character.
Here In the cross between a red flowering plant and the pink flowering plant, the character shows the incomplete dominance.
Let the allele for dominant character i.e red flower be R and recessive character white be r.
So the genotype for red flowering plant = RR.
The genotype for pink flowering plant =Rr.
The gametes from red flowering plant =R.
The gametes from pink flowering plant =R and r.
So with the cross, the genotype of the offsprings will be 50% RR and 50% Rr.
So plants with red flowers will be 50% of the whole progeny.
Answer:
Explanation:
Homo erectus existed about 200 million yeas ago as one of the early man to occupy the old world. Homo erectus are said to be the direct ancestors of other homos. The brain size of homo is population dependent and it ranges from 546–1, 251 cc (33.3–76.3 cu in). The maximum size of the brain was achieved early in their life to
this is similar to childhood in modern human.
Body size ranged widely from 146–185 cm which is about 4 feet 9 inches –6 feet 1 inch in height and 40–68 kg in weight.
Homo erectus have a flat skull that is low. The face is also flat compare to modern humans with brow ridge.
The vast majority of energy in food webs originates from the sun. Energy is not recycled in ecosystems and each ecosystem requires a continuous input of energy to sustain it. There is some energy transformed at each level of the food chain or food web in an ecosystem.
Answer:
A karyotype is the individuals collection of chromosomes
you can use the individuals karyotype to determine if a fetus has down syndrome by looking at chromosome 21. If the fetus has an extra copy of chromosome 21, it will have down syndrome.

<h2>Allosteric enzyme</h2>
Explanation:
- Allosteric regulation, extensively, is only any type of regulation where the regulatory molecule (an activator or inhibitor) ties to a protein somewhere other than the dynamic site. Where the controller ties is known as the allosteric site.
- Essentially all cases of noncompetitive restraint (alongside some novel instances of serious hindrance) are types of allosteric regulation.
- A few chemicals that are allosterically controlled have a lot of one of a kind properties that set them apart. These compounds, which incorporate a portion of our key metabolic controllers, are regularly given the name of allosteric enzymes
- Allosteric enzymes commonly have various active sites situated on various protein subunits. At the point when an allosteric inhibitor binds to a enzyme, every single dynamic site on the protein subunits are changed slightly so they work less well.
- There are also allosteric activators. Some allosteric activators tie to areas on a chemical other than the dynamic site, causing an expansion in the capacity of the dynamic site. Additionally, in a procedure called cooperativity, the substrate itself can fill in as an allosteric activator: when it ties to one dynamic site, the action of the other dynamic destinations goes up. This is considered allosteric regulation in light of the fact that the substrate influences dynamic locales a long way from its coupling site.
