People who have Tay-Sachs disease cannot metabolize some lipids effectively. Tay-Sachs is a recessive disorder. A student used a Punnet Square to determine the probability of offspring inheriting the disease. The results from a Punnet Square are 25% TT, 50% Tt, and 25% tt.
Which conclusion can be made regarding the phenotype of the parents based on these results?
The parents must be TT, Tt
The parents must be Tt, tt
The parents must be TT, tt
The parents must be Tt, Tt
Answer:
The parents must be Tt, Tt
Explanation:
Based on these results, we can conclude that each of the parents will have one dominant (T) and one recessive allele (t). We can prove this by drawing the Punnett square:
T t
T TT Tt
t Tt tt
We can see that the offspring will have the Tt genotype in two cases, the TT genotype in one case, and the tt genotype in one case, as well. Now we need to do some basic math. Two out of four is 50% (Tt - 50%), and one out of four is 25% (TT - 25%, tt - 25%).
This means that the parents must be Tt, Tt.
can someone please help me with this
Answer:
Nitrogenous base
Explanation:
Phosphate and deoxyribose create the "backbone" of a DNA molecule.
Think of the molecule as a ladder.
These(deoxyribose and phosphate) are the sides of the latter.
The nitrogenous bases(A,G,C,T) are the rungs of the ladder.
As the arrow points to the "rung" of the ladder, that means it is a nitrogenous base.

how many body systems are in eating a single bite of turkey? PLSS HELP its duo in abt 6 mins!!
Answer:
There are 4 systems involved in this activity. these systems are: the skeletal, muscular, circulatory and digestive systems.
Explanation:
To eat a single bite of turkey it is necessary that 4 systems come into play and work together for this activity to be possible.
First, it is necessary that the turkey is brought to your mouth through the movement of its members. In that sense, the resqueletico and muscular systems will act because it is through them that the movements of the members are created.
Then you will need to bite the turkey, chew it, moisten it with saliva, swallow it and digest it. This work will be done with the digestive system that will manage all of these activities.
Finally, your body will need to absorb the elements that make up the turkey pedal that you ate and that were rescued by digestion, these elements are nutrients, proteins and others. All will be absorbed through the work of the circulatory system, which through the blood will carry the elements throughout the body.

On ed2020 its D
Explanation:
In individual's life, personality is capable to change and also being stable over the course of development, hence option d is correct.
What is personality?At other words, rather than a progressive growth, development happens in different levels. The term "development" has a favorable meaning, its meaning varies depending on how it is used.
Typically, the word "development" indicates growth, it refers to a time when things transform and develop. Additionally, it tends to encourage people to reach their maximum potential.
Therefore, it may also refer to a different interpretation of an earlier occurrence, personality can change or be stable, hence option d is correct.

Answer:
By crossing plants with purple flowers, dominant, with plants with white flowers the offspring will be 100% purple because all the offspring will receive at least one dominant allele.
Explanation:
The crossing of two plants of pure line, one dominant and one recessive, for a trait —the color of the flowers— will produce a hybrid offspring which will express the dominant trait in its phenotype.
Parental generation:
Plant with purple flowers PP Plant with white flowers ppCross: PP X pp
Punnett Square :
Alleles P P
p Pp Pp
p Pp Pp
Offspring: 100% Plants whose phenotype is purple flowers and Pp genotype.
According to this, the descendants will be 100% plants with purple flowers, hybrids, since all the offspring received at least one dominant allele.
A student is observing a single-celled alga and knows that it undergoes photosynthesis and respiration. Which question could the student ask to find out how it can do both processes?
The options associated with the question is :
Are the inputs of photosynthesis the same as the outputs of respiration?
Are the inputs of photosynthesis the same as the inputs of respiration?
Is water needed for the processes of respiration and photosynthesis?
Is carbon dioxide needed for the process of photosynthesis?
Answer:
The correct answer is - Are the inputs of photosynthesis the same as the outputs of respiration?
Explanation:
To understand that it is able to perform both the process photosynthesis and cellular respiration by this single cell of alga it is required to understand the process of both processes and how they provided to the alga.
Photosynthesis is the process that converts water and carbon dioxide into glucose and oxygen as the output or products. Glucose is further used in the cellular respiration with oxygen to produce water and carbon dioxide. So it make balance of the inputs and outputs in the both reaction so it can be understand by asking if the inputs of photosynthesis the same as the outputs of respiration?
Photosynthesis and respiration both are shown by algae because they need light to make food.
Algae are a diverse group of predominantly photosynthetic organisms, including cyanobacteria, green algae, and other eukaryotes. They account for more than 50% of the photosynthesis that occurs on Earth. Photosynthetic efficiency is higher in algae than in higher plants. Algae use carbon dioxide for cellular respiration. It binds CO2 and reduces the amount in the atmosphere.
The questions which students can ask are :
Are the inputs to photosynthesis and the outputs to respiration the same?
Are the photosynthesis and respiration inputs the same thing?
Is it true that water is required for respiration and photosynthesis?
Is carbon dioxide required for photosynthesis?
what are algae?A group of photosynthetic, aquatic, marine, true root stems leaves bearing organisms.
thus it concludes algae can perform both cellular respiration and photosynthesis.
To know about algae refers to the link:

Form a hypothesis: How do you think photosynthesis is related to cellular respiration?
Answer:
photosynthesis makes the glucose that is used in cellular respiration to make ATP while photosynthesis requires carbon dioxide to release oxygen cellular respiration requires oxygen that releases carbon dioxide it is the release oxygen that is used by US and most other organisms for cellular respiration. have a nice day!!!!
Answer:
It is. (It is a lot for a hypothesis)
Explanation:
Cellular respiration is backwards (C6 H12 O6 + 6 O2 --> 6 CO2+ 6 H2O + Energy). Here, glucose and oxygen are the reactants. With photosynthesis, glucose and oxygen would be the products. Same thing with the products of cellular respiration. Carbon dioxide and water are the products of cellular respiration, while they are the reactants in photosynthesis.

Si una planta homocigótica de tallo alto (AA) se cruza con una homocigótica de tallo enano (aa), sabiendo que el tallo alto es dominante sobre el tallo enano, ¿Cómo serán los genotipos y fenotipos de la F1?
Answer:
Genotipo: 4/4 o 100% de la progenie será Heterocigota para la característica altura del tallo, Aa.Fenotipo: 4/4 o 100% de la progenie expresará tallos altos.Explanation:
Datos disponibles:
Característica: Altura del talloAlelo dominante, A, expresa tallo alto en homocigosis (AA) y en heterocigosis (Aa).Alelo recesivo, a, expresa tallo enano en homocigosis (aa).Cruza: una planta homocigótica de tallo alto con una homocigótica de tallo enano (aa)
Parentales) AA x aa
Fenotipos) Tallo alto Tallo enano
Gametos) A A a a
Cuadro de Punnet) A A
a Aa Aa
a Aa Aa
F1) Genotipo: 4/4 o 100% de la progenie será Heterocigota para la característica altura del tallo, Aa.
Fenotipo: 4/4 o 100% de la progenie expresará tallos altos.
Nota: Por conocimiento teórico, es posible que no sea necesario el uso del cuadro de Punnet para realizar esta cruza. Esto es porque sabiendo que uno de los parentales es homocigota dominante y el otro parental homocigota recesivo, con un solo gen dialélico involucrado en la cruza, indefectiblemente la progenie será heterocigota. Un parental solo puede ofrecer gametos dominantes para la característica mientras que el otro parental solo puede ofrecer gametos recesivos. Aún asi, el cuadro de Punnet siempre resulta útil para poder visualizar bien los cruzamientos, siempre que estos últmos involucren pocos genes.

Explanation:
Shameeka is studying for an exam. She took the notes below about calcium and chlorine, which are known to form ionic bonds.
Calcium, which is a metal, donates 2 electrons to chlorine.
The individual calcium atoms become ions with a negative 2 charge.
The bond between calcium and chlorine makes the atoms stable.
Calcium and chlorine attract each other.
Which best describes Shameeka’s error?
Calcium is a metal, so it donates protons, not electrons.
The individual calcium atom has a positive, not negative, 2 charge.
The bond formed makes the atoms unstable, not stable.
Calcium and chlorine repel, not attract, each other.
Answer:
The individual calcium atom has a positive, not negative, 2 charge.
Explanation:
The error in her study is in the second line of her note which suggests that the individual calcium atoms becomes ions with a negative 2 charge.
When atom loses electrons, it has a net positive charge on it. Not a negative charge. This is because the number of protons is now more than electrons. Therefore, a net charge on the calcium atom will be a positive one. This is her mistake.Answer:
B) The individual calcium atom has a positive, not negative, 2 charge.
