Answer:
D
Explanation:
It is transferred as heredity.
Molecules (DNA) that contain the information that determines eye color are passed from parents to children.
Parents pass there genes to there offspring which helps in determining there phenotype.What are genes?A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. Many genes do not code for proteins.What are proteins?A protein is a naturally occurring, extremely complex substance that consists of amino acid residues joined by peptide bonds. Proteins are present in all living organisms and include many essential biological compounds such as enzymes, hormones, and antibodies.

Which organelle is most directly involved in energy transformations within cells?
A. chloroplast
B. nucleus
C. ribosome
D. endoplasmic reticulum
The two major cell organelles involved in energy transformation are mitochondria and chloroplasts. Thus option A is correct.
what is function of chloroplast ?Chloroplasts are the cellular organelle found in photosynthetic organism like plants and algae.
They are present in mesophyll cells of leaves and contain a high concentration of chlorophyll which absorb sunlight; It is absent in animal cell.
Chloroplast has extra-nuclear DNA and are semiautonomous.
They synthesize food by the process of photosynthesis by absorbing sunlight into chemical energy.
It is major production house of NADPH and molecular oxygen (O2) by photolysis of water; It produces ATP from photosynthesis.
It also indirectly involve in generation of carbon and sugar molecule during the Calvin Cycle or dark reaction of photosynthesis.

List in order the various fluid compartments that a glucose molecule would encounter beginning with absorption from the lumen of the intestine and ending with the glucose molecule entering a skeletal muscle cell.
Answer:
The correct list of compartments glucose enter is :
The lumen > plasma (extracellular fluid) > interstitial fluid (extracellular fluid) > the skeletal muscle cell (intracellular fluid)
Explanation:
The glucose molecule would start from the lumen of the intestine where is absorbed. The glucose enters the plasma a part of the circulatory system known as extracellular fluid.
The glucose also encounters another type of extracellular fluid the interstitial fluid that is not in the circulatory system. At the last glucose as it is entering the skeletal muscle cell the last fluid compartment, which is intracellular fluid. This fluid is inside the cells.
Skeletal muscles are the elongated and elastic cells and fibers also known as the sarcolemma that have numerous nuclei in the periphery of their cells. They are majorly found in the diaphragm, throat, eyes etc.
The correct order of the compartments in which the glucose enters is lumen, plasma (extracellular fluid), interstitial fluid and the skeletal muscle cell.
How does the glucose flow from the digestive system to the muscles?Glucose is derived from the food and the nutrient molecule an organism intakes that reaches the lumen present in the intestine of the digestive system.In the lumen, the glucose molecules get absorbed and then enters the plasma that is the part of the circulatory system, which is also an extracellular fluid.In the plasma, the glucose also encounters the other extracellular fluids and then enters the skeletal muscle cells for providing energy which is the last fluid compartment and are intracellular fluid.Thus, the glucose enters the lumen, plasma, interstitial fluid and skeletal muscle cells.

(infant dies in the womb.) which allele, the mutant allele or the wild-type allele, is dominant with respect to viability
Answer:
The correct answer is - wild type in respect of viability.
Explanation:
Achondroplasia is a condition of dwarfism and it takes place due to a mutant allele which autosomal dominant in nature which means only one copy of the mutant allele is going to cause dwarfism in an individual.
We also know that if two copies of the mutant allele are present then it will be lethal and will not be viable so in respect of expression the mutant allele is dominant, however, in respect of the viability, the wild type is dominant.

Aaminah saw a sparrow eating a caterpillar. She also noticed that the mango tree in her garden was covered in caterpillars. A food chain linking these organisms is: *
choose one of these
Caterpillars -> Mango tree -> Sparrow
Mango tree -> Caterpillar -> Sparrow
Mango tree -> Sparrow -> Caterpillar
Sparrow -> Caterpillar -> Mango tree
Mango tree > Caterpillar > Sparrow
The first level in a food chain should be a primary producer which is the mango tree.
The second level in a food chain should be Primary consumer which is the caterpillar.
The third level in a food chain should be the secondary consumer which is the sparrow.
A food chain always starts from left to right. This from the primary producer then to the other levels. np

Name a sense organ involved in a reflex co-ordinated by the spinal cord.
Answer:
sense of touch
Explanation:
There are five sense organs that involved vision, hearing, taste, smelling, and touch.
Sense of touch is involved in a reflex coordinated by the spinal cord as when we touch something, sensory nerves sends the information to the brain and spinal cord. the motor nerves process the signals in the brain and send it back to the muscles, that leads to contraction reflexively.
Hence, the correct answer is "sense of touch".

A model of a plant cell is shown.
Which of the structures are present in plant cells, but not in animal cells? Select all that apply.
The question is incomplete, however, the missing part of the question is as follows:
nucleus, chloroplast, Golgi apparatus, cell wall
Answer:
The correct answer is - cell wall and chloroplast.
Explanation:
Plant cells and animal cells both are eukaryotic cells and most of the cellular structures are the same, however, the plant cells have few adaptions that make them different from animal cells.
Plant cells have a cell wall outside of their plasma membrane that provides support and protects the cell from injuries. Cell wall not present in an animal cell. The other structure that presents in plant cells and not in animals is chloroplast that helps plants to produce their food by the process of photosynthesis.

Indicate the expected number of Barr bodies in interphase cells of individuals with Klinefelter syndrome; Turner syndrome; and karyotypes 47,XYY, 47,XXX, and 48,XXXX.
Answer:
Barr bodies are small bodies that are dark staining bodies that show the inactivated X chromosome, these sex chromatin bodies attach to the membrane of the nucleus of interphase cells.
One less of the total number of X-chromosome (n-1) represents the number of Barr bodies.
Then,
The number of Barr bodies with Klinefelter would be:
Klinefelter (47,XXY): (n-1) = (2-1) = 1 Barr body as here two X chromosome present.
Similarly, for
Turner (45,XO): (n-1) = (1-1) = 0 Barr bodies (X chromosome = 1)
Now, as per the question, the bar bodies for karyotypes given
47,XYY: (n-1) = (1-1) = 0 Barr bodies
47,XXX: (n-1) = (3-1) = 2 Barr bodies
48,XXXX: (n-1) = (4-1) = 3 Barr bodies

Salmon live in both fresh water and salt water during their lives. They are born in in fresh water but migrate out to marine waters for most of their life. Eventually, they return to the place they were born in fresh water to spawn. Changing between fresh water and salt water affects the balance of water in their body. Salmon have an internal control system called osmoregulation that restores the balance by negative feedback. This is an example of which characteristic of life
Answer: The question is incomplete because the options are not given. Here are the options gotten from another website.
A. adaptation
B. reproduction and development
C. response to the environment D. energy transformation
E. maintaining homeostasis
The correct option is maintain homeostasis which is C.
Explanation:
This is because salmon posseses adaptive physical characteristics that help it to suitably live both in freshwater and salt water. This is because homeostasis is the ability to resist any change in order to maintain body internal environment and this is a negative loop feedback. Organs of salmon work to control homeostasis but endocrine and nervous system engage more in maintain homeostasis.
The last option is correct.
