study the punnett square below. what percentage of the offspring are heterozygous
Answers
Answer:
50%
Explanation:
Heterozygous is when both of the alleles are different. Since AA and aa are the same allele, the other two Aa and Aa have on capital and one lowercse and for that reason they are different and thus heterozygous. Since 2.4 are heterozygous, 50% is the answer.

pls help i need answer asap! The digestive system is a group of organs working together to convert food into energy and basic nutrients that are transported throughout the body. Food passes through a long tube inside the body known as the alimentary canal, made up of the oral cavity, pharynx, esophagus, stomach, small intestines, and large intestines. Once food is chewed, the bolus is moved into the stomach for further digestion. Examine the Interconnections chart and select the body system that is responsible for moving the food from the start to the finish of the digestive system.

Answers
Question:
Use the following dichotomous key to identify an irregular blue flower with five petals and a fruit that is a ripened flower ovary or follicle.
Dichotomous Key of Ranunculaceae
#1.
a. Fruit is a group of alkenes.............................. go to step 2
b. Fruit is a group of follicles..............................go to step 4
#2.
a. Petals are not present.....................................go to step 3
b. Petals are present............................................Ranunculus
#3.
a. The flower has 4 sepals.................................. Clematis
b. The flower has 5 sepals................................... Anemone
#4.
a. The flowers are regular..................................... Aquilegia
b. The flowers are irregular................................... Delphinium
The flower is a: A. Anemone B. Clematis C. Delphinium D. Ranunculus
Answer:
The species belongs to Delphinium genera.
Explanation:
A dichotomous key is relatively simple to interpret. All you need to do is to:
- carefully observe your organism,
- know some technical terms or have a biological dictionary, and
- follow the descriptions.
The dichotomous key is going to lead you to the answer.
In the example, we have a plant species with irregular blue flowers and five petals. The fruits are a ripened flower ovary or follicles.
Irregular flower: Term that refers to asymmetrical flowers that only have one plane. Follicle: Term that refers to dry dehiscent fruits originated from a flower with only one carpel. When mature, they open by the ventral suture.So, let us begin, step by step. For each number, we are going to have two options (a and b). By knowing our organism, we need to decide which one is correct and follow indications.
#1.
a. Fruit is a group of alkenes.............................. go to step 2.
b. Fruit is a group of follicles..............................go to step 4.
We know that our fruit is a follicle. Option a is not correct (it is not a group of alkenes). Option b is the correct one. Knowing this, we must go to step four. ***Note: In the hypothetical case that the fruits were a group of alkenes, and option a was correct, we should go to step two, as indicated***.
#4.
a. The flowers are regular..................................... Aquilegia
b. The flowers are irregular................................... Delphinium
We know that our flower is an irregular one. So the correct option is b. This option leads us to Delphinium genera. Our species belongs to this taxonomic group. ***Note: In the hypothetical case that the fruit was actually a regular flower, and option a was correct, our species would belong to Aquilegia genera***

Answer:
the correct answer is c
Explanation:
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.

Explanation:
A group of students were interested in showing photosynthesis occurring visually. They decided to use bromothymol blue which is an indicator that turns green when there is a high concentration of carbon dioxide and blue when there is a low concentration of carbon dioxide in water. All the tubes started out blue, but students blew carbon dioxide into two of the test tubes turning them green. They left one test tube of each color as their control and put a piece of aquatic plant in the other two tubes. Then, they put all four of these tubes outside (Monday 7 am). When the students checked their tubes in the afternoon (Monday 1 pm), they were so excited to see that tube D had turned blue! Carbon dioxide was going away and being replaced with oxygen. When the students checked their experiment early the next morning, tube B and D had both turned green! Did photosynthesis occur during the experiment? Support your claim with evidence explain your reasoning.
Answers
Answer:
photosynthesis did not occur.. because if photosynthesis had occured oxygen would be produced..but the tubes turned green proving there was more carbondioxide than oxygen Which proves photosynthesis didn't take place.

As the test tube turned green, it means that photosynthesis did not occur in the test tubes.
What is bromothymol blue?Bromothymol blue (BMB) is a dye that turns yellow when exposed to acid. When carbon dioxide is added to a solution, it produces carbonic acid, which lowers the pH.
When the pH is greater than 7.6, BMB is blue, green when the pH is between 6-7.6, and yellow when the pH is less than 6.
Carbon dioxide dissipates in water to produce a weak acid. As a result, an acid-base indicator like bromothymol blue (BTB) can be used to detect the presence of CO2.
The person basically use bromothymol blue as an indicator to determine how much CO2 remains in test tubes containing light-exposed plants.
Thus, as there were some drawbacks in the experiment, the test tube B and D got green color, which means the level of carbon dioxide were more. This implies, photosynthesis did not occur.
