achondroplasia is a form of dwarfism in humans. it is caused by a mutant allele of the fibroblast growth factor receptor (fgfr) gene that produces an overactive protein. having one copy of the mutant allele results in dwarfism. having two copies of the mutant allele results in stillbirth. (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.

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.
Thus option A is correct.

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.

A STOMACHE IS AN ORGAN!!!!
An organ is a collection of tissues that structurally form a functional unit specialized to perform a particular function.
_____________________________________[tex]\Huge\text{Levels of Biological Organization}[/tex]Cell - The smallest unit of life. Example: Red Blood Cell Tissue - A group of similar cells that perform a specific function. Example: Muscle Tissue Organ - A structure within an organism usually composed of several tissue types that form a functional unit. Example: Stomach Organ System - Two or more organs working together in the execution of a specific bodily function. Example: Respiratory System Multicellular Organism - An individual living thing. Example: A single H.o.m.o Sapiens(Human Being). Species - Very similar, potentially interbreeding organism. Example: All cats, dogs, humans. Population - Members of one species inhabiting the same area. Example: Population of people living in USA Community - Two or more populations of different species living and interacting in the same area. Example: Cats and Hooomans living together in the same area or house. Ecosystem - A community together with its non-living surroundings.

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
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
he reflexes from sense organs in the head are co-ordinated by the brain.
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".
