Cellular respiration is the chemical basis of how cells release energy from foods. When you eat an apple, your cells extract energy. The text below explains how cells use cellular respiration to extract energy from an apple. Choose the parts of the sentence that are incorrect.
The apple first enters the digestive tract through the mouth, where digestion begins with chewing. Enzymes begin to break down the apple in the mouth. From the digestive tract, the glucose from the digested apple is absorbed into the bloodstream, where it is brought to cells throughout the body. In the chloroplast, the glucose begins cellular respiration. The molecules react with carbon dioxide to release energy. Oxygen is produced as waste
Answer:

If a double-stranded segment of DNA has been found to have 23 purines and 15 thymines, how many guanines are there?
Answer: 4 Guanines
Explanation: Following Chargaff's ratio that describes the ration of purines to pyrimidines as 1:1, if there are 23 purines, it follows that there should be 23 pyrimidines; 15 Thymines should therefore be hydrogen bonded to 15 Adenines by complementary base pairing.
We are then left with 8 nucleotides composed of guanines and cytosines in complementary base pairs. This means that half that number (4) should be guanines and the rest cytosines.
The DNA is a double-stranded molecule, which is made up of purine, pyrimidine, a pentose sugar, and phosphate backbone. Chargaff's rule states that any species will have a stoichiometric ratio of 1:1.
The number of guanines in the double-stranded DNA is 4.
In the DNA, the base pairing occurs as:
The guanines bind with cytosine through hydrogen bonding. The adenine binds with thymine with two hydrogen bonds.In the given nucleotide, there are 23 purines (guanine and adenine). There are 15 thymines in the DNA molecule. Based on the Chargaff rule, the 15 thymines will bind to adenine, leaving only 4 guanines and 4 cytosines. Thus, there will be 4 cytosines left to bond with the guanines to achieve Chargaff's ratio of 1:1.
Therefore, the guanine in the nucleotides will be 4.

1. The parts of the flower involved in reproduction are ________ and __________
2. The anthers bear the ___________the microspore mother cells give rise to _______or pollen grains after meiotic cell division.
Answer:
1. Stamen and pistil
2. Pollen, microspore
Explanation:
The flower is the reproductive part of certain plants called ANGIOSPERMS. They make use of their flower for sexual reproduction. The different parts of the flower work together to achieve a common goal, which is to reproduce, however, they do it in various ways. For example, accessory parts like petals attract pollinators. The major parts of the flower that are directly involved in the reproductive act are STAMEN (male) and PISTIL (female).
The stamen which constitutes a structure called ANTHER bears the pollen grains or microspore, which is made when the microspore mother cells undergo meiotic division. Hence, the pollens are released from the anther of a male flower (stamen), into the stigma of the female flower (pistil).

What structure provide shape and support for the cell?
A.Chloroplast
B.Mitochondria
C. cell Wall
D.Golgi bodies
The cell wall provides shape and support for the cell. Therefore, option (C) is correct.
What is cell wall?In the cells of plants, fungi, and some bacteria, the cell wall is a strong structure that encloses the cell membrane. It has a solid and strong structure because it is formed of chitin, which is found in fungi and cellulose in plants. The cell wall supports it mechanically, shields it from harm, and aids in keeping its shape. Moreover, it stops the cell from bursting or collapsing under pressure, which is crucial for plant cells because they must maintain turgor pressure in order to function properly.
Animal cells, on the other hand, lack a cell wall and instead contain a cytoskeleton formed of protein fibers that gives them stability and shape. Organelles that perform photosynthesis include chloroplasts, mitochondria, and golgi bodies, which also produce energy and process and transport proteins inside of cells.

You can tell the age of a skeleton by looking at:
O1) the length of the femur
O2) the shape of the pelvis
O 3) the number of fused bones
O4) the color of the bones
Answer:
Calculating the age of a skeleton can be done by looking at the number of fused bones (option 3).
Explanation:
The calculation of skeleton bone age takes into account the complete ossification of bones, which occurs at various stages of human development.
In childhood, the epiphyses or ends of long bones are not completely ossified but are formed by cartilage, due to the process of growth. When development is achieved, the growth nuclei and cartilage disappear.
Bone age is a reliable parameter for calculating chronological age, as they are quite approximate.
The other options are not correct because:
1. The length of the femur is useful for calculating height.
2. The shape of the pelvis helps to differentiate the sex.
4. The color of the bones is not a useful parameter to calculate the age of the skeleton.
