1. What percentage of the offspring will be heterozygous?
2. Why does each parent contribute only one allele to the offspring?
Answers
Answer:
1. 50%
2. Every gamete only contains 50% of the genetic information or half of the information for a gene.
Explanation: 1. Heterozygous means the pairs consist of a dominant and a recessive, or one big and one small letter, so only 2/4 or 50% are heterozygous.
2. Every sex cell has half of the chromosomes you need to make an embryo so you end up only having one allele as well
Heterogeneous means different
Here they are 2Total 4Percentage:-.
2/4×100=50%#2
It's because they only produce 50% not 100%

What factors could decrease the rate of photosynthesis in a plant?
Answers
Answer: light intensity, carbon dioxide concentration and temperature i think- maybe
Explanation:
Without enough light, a plant cannot photosynthesise very quickly, even if there is plenty of water and carbon dioxide, Increasing the light intensity will boost the rate of photosynthesis and for carbon dioxide even if there is plenty of light, the plant cant photosynthesise if there is insufficient carbon dioxide. and why temperature is because if it gets too cold the rate of photosynthesis will decrease, Plants cant photosynthesise if it gets too hot either

Explain why some parts of a plant can act as both a source and a sink.
Answers
Answer:
Some organs are both a source and sink. Leaves are sinks when growing and sources when photosynthesizing. Rhizomes are sinks when growing but become sources in the spring when they provide energy for new growth.
hope this helps ☆☆☆
The leaves and rhizomes of the plant are found to act both as a source and a sink when growing and when they perform photosynthesis.
What are source and sink in plant?
Source organs are the organs which provide a net uptake of resources while sink organs are the organs which have a net drawdown of resources in the plant. Molecular mechanisms which are responsible for the regulation of the relationship between the sources and sinks. These molecular mechanisms include both the carbon and nitrogen-containing metabolites, plant hormones and genes.
Some organs in the plant are found to act both as a source and a sink. Leaves of the plant are sinks when growing and as source when photosynthesizing in the presence of sunlight during daytime. Rhizomes are the sinks when growing however they become sources in the spring season when they provide energy for the new growth.

The fence around the school's garden is 22.6 m. If the garden is 7.5 m long, how wide is the garden? *
Answers
Answer:
Explanation:
22.6 is the perimeter because the question has the key words "fence" and "around" that let us know.
Perimeter equation is L+L+W+W
We know 7.5 is the length (could also be the width, it doesn't matter the order)
The length appears two times, so lets plug it in-
22.6= 7.5+7.5+W+W , Now you want to combine the like terms so.. 7.5+7.5=15
22.6= 15+W+W
Now subtract the 15 from 22.6
7.6= W+W , there are two W's left so divide 7.6 by 2
7.6/2= 3.8
It is 3.8 m wide

What is the rarest eye colour in the world? Please help, it's due today.
Answers
Answer:
Green eyes
Explanation:
The production of melanin in the iris is what influences eye color. More melanin produces a darker coloring, while less makes for lighter eyes. Green eyes are the rarest, but there exist anecdotal reports that gray eyes are even rarer.
The rarest eye color in the world is green, only 2% of the population in the world have green eyes. To find out more about the list.....
1. Green eyesOnly 2% of people in the world are believed to have this eye color. It is most easily found in northern and Southern Europe and Western Asia.
2. Amber eyesThey are reddish-brown, with a golden and coppery undertone. Among the clear and beautiful eyes in the world, and according to the survey, the most iris, all eyes and beautiful in the world are according to the study, all eyes are rare and specific.
3. Red or violet eyeIt is generated by the body thanks to some genetic changes. The most common is albinism, a disease that lowers melanin levels. Because of this, the hair and eyes can be distinguished.
With this information, we can conclude that there are several eye colors, but the most rare is the color green.

Why do you have to determine the total magnification when observing a specimen under the compound microscope?
Answers
Answer:
To clearly see specimens under the microscope, and to be able to see two separate objects that are close together.
Explanation:
A microscope is a tool that makes an object look bigger so that the person who is looking at it can see it. It's important to use a microscope because cells are usually too small to see with the naked eye. In addition to magnification, microscopes also have resolution, which is the ability to see two objects that are close together as separate. A microscope needs both magnification and resolution to be able to clearly see specimens under the microscope. When the light microscope bends light at the specimen, it gives the viewer a clear picture of the specimen. A series of lenses do this.
A student is conducting a breeding experiment. She knows the genotype of one parent plant and concludes that she can use a Punnett square to predict the outcome of crossing the plant with another plant. Which statement best explains why this conclusion is incorrect?
a. She needs to know the phenotypes of the previous plant generation.
b. She needs to know the phenotype of the first plant.
c. She needs to know the genotypes of the previous plant generation.
d. She needs to know the genotype of the second plant.
Answers
D. She needs to know the genotype of the second plant.
What is a punnett square?A Punnett square is a tool used to predict the outcome of a genetic cross between two individuals. To use a Punnett square, you need to know the genotypes of both of the individuals involved in the cross. In this case, the student knows the genotype of one parent plant, but does not know the genotype of the second plant.
Therefore, she cannot use a Punnett square to predict the outcome of the breeding experiment. In order to do so, she would need to know the genotype of the second plant.

As a metal, lithium will lose electrons to have a ful valence shell. How manyvalence electrons will it lose to have full valence shell? What will be the charge of the lithium ion?
please help me
Answers
Answer:
It will lose 1 electron
Its charge will be 1+, or simply (+)
Explanation:
Lithium it's located in the group one of the periodic table, the Alkali, and by rule, all Alkali are always gonna loose one electron during a chemical reaction to form a positive ion.
The charge is explained by the fact that, if lithium looses one electron, then it wi have less number of electrons than protons, meaning that, if there's a higher number of protons (positive charge), then the charge will be positive. And since the atom loosed one electron then its charge will be 1+
For example, during a chemical reaction calcium is always gonna loose 2 electrons, so its charge's gonna be Ca2+
