In humans, long eyelashes (L) are dominant to short eyelashes (l). For the three boxes containing possible genotypes for eyelash length, we can match the terms/phrases on the right with their correct genotypes.
1. Homozygous dominant (LL): This genotype represents individuals with two dominant alleles (LL) for long eyelashes.
2. Heterozygous (Ll): This genotype has one dominant allele (L) and one recessive allele (l) for eyelash length, resulting in long eyelashes due to the dominance of the L allele.
3. Homozygous recessive (ll): This genotype consists of two recessive alleles (ll) for short eyelashes. Since there is no dominant allele present, the individual will have short eyelashes.
Some labels may be used more than once, while others may not be used at all in matching the terms/phrases with their correct genotypes.

Single circulation i.e., blood flows through the heart only once during one cycle of passage through the body, is exhibited by
a. Labeo, Chameleon, Salamander
b. Hippocampus, Exocoetus, Anabas
c. Hyla, Rana, Draco
d. Whale, Dolphin, Turtle
Single circulation i.e., blood flows through the heart only once during one cycle of passage through the body, is exhibited by fishes like Labeo, Chameleon, Salamander, etc. Therefore, option (a) is the correct answer.
Single circulation, also known as the incomplete circulatory system, is found in fishes, and it describes the passage of blood through the heart only once during one cycle of circulation through the body. The circulation process consists of blood moving from the heart to the gills, where it releases carbon dioxide and receives oxygen. The blood then moves to the body and organs, delivering oxygen to the cells before returning to the heart to begin the process all over again.The majority of fish have a two-chambered heart, with blood flowing through it only once per cycle. The single circulation pattern is typical of fish because their gills are the primary gas exchange organs. Fish need less oxygen because they are cold-blooded animals. As a result, the oxygen-poor blood from their body organs mixes with the oxygen-rich blood from the gills.

Specifically, molecules of chlorophyll are located in membrane sacs called:
a. stroma.
b. cristae.
c. vesicles.
d. thylakoids.
e. vacuoles.
Molecules of chlorophyll are located in membrane sacs called thylakoids. Hence, d. is the correct option.
Among the options given, the molecules of chlorophyll are specifically located in membrane sacs called thylakoids. Thylakoids are specialized structures found within chloroplasts, the organelles responsible for photosynthesis in plant cells. They are flattened, disc-like structures that are stacked together to form structures known as grana.
Inside the thylakoids, chlorophyll molecules are embedded in the thylakoid membrane. Chlorophyll is a pigment that plays a crucial role in capturing light energy during the process of photosynthesis. It absorbs light energy from the sun and converts it into chemical energy that can be used to fuel the synthesis of glucose and other organic molecules.
The arrangement of chlorophyll molecules within the thylakoid membrane allows for the efficient capture of light energy and its conversion into chemical energy. This energy is then used to drive the series of chemical reactions that occur during photosynthesis.
Therefore, molecules of chlorophyll are located in membrane sacs called thylakoids, which are part of the chloroplasts and are involved in the process of capturing and converting light energy during photosynthesis.

ikaros encodes a transcription factor and is expressed in neural stem cells of the visual cortex but only during the first two neural stem cell divisions. if ikaros functions as a temporal identity factor, what would you expect: (a) ikaros expression to look like in stem cells in other areas of the developing cortex (would it be in all stem cells, what would the timing of expression be)?
In other areas of the developing cortex, I would expect that Ikaros expression would not be present in all stem cells, but rather exhibit a spatially and temporally regulated pattern.
Since Ikaros functions as a temporal identity factor in neural stem cells of the visual cortex, its expression in other cortical regions would likely be limited to specific subsets of stem cells during distinct developmental time windows. The expression timing would depend on the specific developmental events and processes occurring in those regions.
It is possible that other transcription factors or regulatory molecules might govern the temporal identity of stem cells in those regions, leading to different patterns of gene expression and cell fate determination. Studies have shown that the expression of transcription factors can exhibit regional and temporal specificity during cortical development.

Answer:
1. In the process of photosynthesis, plants convert the energy of sunlight into chemical energy stored in the bonds of carbohydrates.
a. The light-dependent reactions use light energy to make two molecules needed for the next stage of photosynthesis: the energy storage molecule ATP and the reduced electron carrier NADPH. In plants, the light reactions take place in the thylakoid membranes of organelles called chloroplasts.
b. In the Calvin cycle (light independent reactions), carbon atoms from CO2 are fixed (incorporated into organic molecules) and used to build three-carbon sugars. This process is fueled by, and dependent on, ATP and NADPH from the light reactions. Unlike the light reactions, which take place in the thylakoid membrane, the reactions of the Calvin cycle take place in the stroma (the inner space of chloroplasts).
2. When transitioning to respiration, photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
3. Cellular respiration is the aerobic process by which living cells break down glucose molecules, release energy, and form molecules of ATP. Overall, this three-stage process involves glucose and oxygen reacting to form carbon dioxide and water.
a. Fermentation refers to the metabolic process by which organic molecules (normally glucose) are converted into acids, gases, or alcohol in the absence of oxygen or any electron transport chain.
4. They are similar because they both produce energy but in two different forms.
Photosynthesis- It produces oxygen and G3P, simple carbohydrate molecules that are high in energy and can be converted into glucose, sucrose, or other sugar molecules.
cellular respiration-During cellular respiration, a glucose molecule is gradually broken down into carbon dioxide and water.
Explanation:
1. A process in which the plants prepares their food from inorganic compounds and light energy is called photosynthesis.
The energy stored in the carbohydrates is used in the preparation of chemical energy.
a. In reactions that use light for the process is called light-dependent reactions. It transpires in the thylakoid organelle of the chloroplast. The light is needed for the synthesis of ATP and NADPH which is a reduced electron carrier.
b. The reactions in which the carbon dioxide is fixed from the carbon source to produce three-carbon sugars is called light-independent reactions. The process of the Calvin cycle transpires in the stroma of the chloroplast.
2. When transpiration changes to the respiratory pathway then glucose is produced during photosynthesis and is used in the process of cellular respiration to produce ATP.
The produced glucose gets converted back into carbon dioxide through the process of expiration.
The water molecules get broken into oxygen during photosynthesis and in another process of cellular respiration, the oxygen combines with hydrogen to yield water.
3. The aerobic process that requires oxygen molecules to break glucose molecules in living organisms to produce ATP and releases energy is called cellular respiration.
The process comprises a reaction between glucose and oxygen to produce carbon dioxide and water.
a. The metabolic process in which the organic molecules are converted to gases, alcohol and acids in the absence of ETC or oxygen is called fermentation.
4. The process of photosynthesis and cellular respiration have similar molecules as:
In the photosynthesis process molecules produced are oxygen, carbohydrates that are high in energy and get converted to glucose or other sugar molecules. In cellular respiration, glucose gets broken into water and carbon dioxide.
