Cellular respiration continues in the mitochondria of the cell with the _____________ cycle and the electron transport chain
Answer:
Cellular respiration continues in the mitochondria of the cell with the Krebs cycle and the electron transport chain.
Explanation:
The Krebs cycle is an important part of the cellular respiration process where —from energetic substrate such as carbohydrates, lipids and eventually proteins— Acetyl-CoA is obtained, whose oxidation produces energy in the form of ATP.
Both cellular respiration and Krebs cycle reactions occur in the mitochondria of the cells of aerobic organisms and, in conjunction with the electron transport chain, have a yield of 24 molecules of ATP for every molecule of glucose entering the system.

Which level of organization is pictured?
cell
tissue
organ
organ system
Plz help ASAP on a timer
Answer: It is a cell
Explanation: Most cells have a honey cone shape.
The image represents the level of organization known as tissue. In the image, the cells are organized into a specific pattern and shape to form a tissue. It is important to note that different tissues can be organized into organs, and organs can be organized into organ systems, which make up the various body systems.
What is a Tissue?A tissue is a group of similar cells that work together to perform a particular function. Tissues can be found in many places in the body and they are specialized to carry out specific functions. For example, muscle tissue is composed of cells that contract and allow movement, while nerve tissue is made up of cells that transmit electrical signals.
The different levels of organization in the body are all interconnected and work together to maintain homeostasis and keep the body functioning properly.

A student claims that the Y chromosome contains the sex-determining region gene, known as the SRY gene, which causes male fetuses to develop testes.
Which of the following provides correct information about cell signaling that supports the claim?
A student claims that the Y chromosome contains the sex-determining region gene, known as the SRY gene, which causes male fetuses to develop testes.
The SRY gene produces a protein that binds to specific regions of DNA in certain tissues, which affects the development of these tissues.
The SRY gene produces a protein that binds to specific regions of DNA in certain tissues, which affects the development of these tissues.
A
The SRY gene produces a protein that deletes portions of the X chromosome in males so that male characteristics can develop.
The SRY gene produces a protein that deletes portions of the X chromosome in males so that male characteristics can develop.
B
The SRY gene produces an RNA segment that is exported from specific cells and targets the developing gonads.
The SRY gene produces an RNA segment that is exported from specific cells and targets the developing gonads.
C
The SRY gene is found only in tissues of the developing gonads.
Answer:
The SRY gene produces a protein that binds to specific regions of DNA in certain tissues, which affects the development of these tissues.
Explanation:
In humans, there are two sex chromosomes namely: X and Y chromosomes. The Y chromosome contains a gene called sex-determining region gene or SRY gene. The SRY gene undergoes genetic expression to produce SRY proteins, which is responsible for the development of male sexual characteristics (testes) in humans.
The SRY protein achieves this by binding to a specific region on the DNA of reproductive tissues and regulates the expression of certain genes i.e. the SRY protein acts as a transcription factor. These regulation causes male fetuses to develop testes and inhibits the development of female sexual characteristics like uterus etc.
The answer option which provides the correct information about cell signaling that supports the claim is: A. The SRY gene produces a protein that binds to specific regions of DNA in certain tissues, which affects the development of these tissues.
A cell is the fundamental (basic) structural, functional and smallest unit of life, that is found in any living organism.
Cell signaling can be defined as a fundamental process through which specific information (signals) are transmitted from the surface of a cell to the cytosol and finally to the nucleus, thereby, causing a change in the gene expression of a living organism.
Basically, cell signaling is an ability of a living cell to do the following from and within its environment:
Process specific information (signal).Transmit specific information (signal).Receive specific information (signal).In Science, the four (4) main stages of cell signaling include:
1. Signal transmission.
2. Cell reception.
3. Signal transduction.
4. Cellular response.
In this context, cell signaling is described by the SRY gene (sex-determining region gene) produces a protein that binds to specific regions of deoxyribonucleic acid (DNA) in certain tissues, which affects the development of these tissues.

Question 1: What motor protein is associated with actin?
Question 2: What is the microtubule organizing center of most eukaryotic cells?
Question 3: Which diseases cause an effect on the cytoskeleton of cells? Do you think a cell can function without a cytoskeleton?
1.This type of enzyme, which converts chemical energy into mechanical energy, is called a mechanochemical enzyme or, colloquially, a motor protein. Myosin is the motor, actin filaments are the tracks along which myosin moves, and ATP is the fuel that powers movement.
2.The microtubule-organizing center (MTOC) is a structure found in eukaryotic cells from which microtubules emerge. MTOCs have two main functions: the organization of eukaryotic flagella and cilia and the organization of the mitotic and meiotic spindle apparatus, which separate the chromosomes during cell division.
3.Cytoskeletal protein aberrations are the underlying reason for many pathological phenotypes. It is no surprise that modifications in such a crucial cellular structure lead to pathological conditions. Indeed, many diseases have now been associated with abnormalities in cytoskeletal and nucleoskeletal proteins, including several cardiovascular disease syndromes, neurodegeneration, cancer (invasion), liver cirrhosis, pulmonary fibrosis, and blistering skin diseases. The mechanisms by which many micro‐organisms infect specific cells have been shown to depend on host cytoskeletal elements. Attempts to modulate the cytoskeleton by peptides or other specific drugs have already yielded interesting results and this will lead to new therapeutic agents in the foreseeable future. The impact on cancer treatment is a convincing example: anti‐cytoskeletal (microtubule targeted) drugs are already used to inhibit cell division.

Most fish can see very well and some fish even have a special eye structure called the Tapetum lucidum that allows them to see very small amounts of light. How does this structure work?(look under sharks for answer)
Answer & Explanation:
Vision is simply the sense or ability of sight; the ability to see or the perception of light. Tapetum lucidum present in most fishes especially the nocturnal ones and sharks, is located behind the retina. It is a special eye structure whose function of which is to return rays of light that have escaped from the retina back to the retina to improve vision. This has enabled them to survive in an environment where light readily disappears due to depth.
A mutation in body cells do not affect future generations, but mutations in gamete (sex cells) will affect future generations.
A.True
B.False
Answer: A. True
Explanation:
Answer:
True
Explanation:
Only hereditary mutations, which occur in egg or sperm cells, can be passed to future generations and potentially contribute to evolution. Some mutations occur during a person's lifetime in only some of the body's cells and are not hereditary, so natural selection cannot play a role.

How have you heard the word metabolism used in daily conversation? How does this usage differ from the actual definition of metabolism?
Answer:
Metabolism - the chemical process within a living organism in order to maintain life
Explanation:
The common use it 'my metabolism is really slow/fast', usually heard in fitness and diet communities. The biggest difference is that, while metabolism does deal with the burning of energy from food, it really covers the processes using all materials such as water, food, nutrients, and oxygen in the cells to produce the body's energy.
Answer: Metabolism is often used in ads for exercise products or diet pills, which claim that they will boost metabolism to help people lose weight. In this context, metabolism is used only to describe weight loss or gain. This interpretation differs greatly from the actual definition of metabolism, which describes all the chemical reactions that occur within a cell.
