Jeff has 10 grams of water and 10 grams of vegetable oil in separate containers. Both liquids have a temperature of 24°C. Jeff heats both liquids over a flame for five minutes. When he’s finished, he discovers that the temperature of the oil increased more than the temperature of the water. What can Jeff conclude from this experiment?
Answers
The temperature of the oil increased more than the temperature of the water because vegetable oil has a lower heat capacity than water.
Heat capacity is the ratio of heat absorbed to temperature change by a material. Typically, it is stated in terms of calories per degree. Oil can hold more heat than water. Compared to water, oil can be heated to high temperatures more quickly with a significantly lower energy input because it has a lower heat capacity than water..Oil transfers heat to food more gradually to a fixed temperature than water does. Oil can be heated to a higher temperature than water when it is in a liquid state.Hence, the correct option is D.

Which muscle is highlighted below?
A. Obliques
B. Rectus abdominus
C. Trapezius
Answers
Answer: B. Rectus abdominus
The highlighted muscle in the image is the rectus abdominus. Therefore, option B is correct.
The rectus abdominus is a paired muscle located in the front of the abdomen. It extends vertically from the pubic bone to the sternum (breastbone). It is a long, flat muscle that plays a key role in core stability, posture, and various movements of the trunk, such as flexion (bending forward) and stabilization.
The rectus abdominis is also known for its characteristic appearance in individuals with well-developed abdominal muscles, often referred to as having a "six-pack."

What is respiration?Inhalation:
On inhalation, the pressure in the alveoli is high, hence the Oxygen diffuses to the nearby blood through the membrane.
Exhalation:
It is the process in which a person releases the air collected in the lung. During exhalation, the pressure in the alveoli is low, hence the carbon dioxide present in the blood is diffused out into the alveoli.
Therefore, the expandable structure of alveoli helps the respiratory system to follow its function.

b Where does it get each of these substances from?
Answers
Answer:
a .carbon dioxide(Co2) and water (H2O)
b. air and soil
Explanation:
During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.

The bottom- and- mouth complaint contagion has been honored since at least the 16th century.
It's characterized by fever, pocks on the bases and mouth, loss of appetite, drooling and lameness. Infected herds of creatures are generally destroyed.Large quantities of the contagion are present in all body concealment, including breath, and are readily transmitted to other creatures. The contagion can also survive on the ground for extended ages of time and can be transferred on tires, thrills and clothes. It has indeed been shown to be carried long distances by wind.The United States has been free of the complaint since 1929, but that isn't a guarantee it'll not return. Britain was free of the complaint for 34 times before a 2001 outbreak that needed the destruction of 10 million cows.FMD contagion is largely contagious in cloven- mashed creatures, including cattle, gormandizers, small ruminants. Encyclopedically, FMD has a significant impact on beast trade economics and expansive nonsupervisory programs live in the U.S. to grease identification of, response to, and control of the complaint.

what is the difference between an epithelial cell and a cardiomyocyte
Answers
The heart is the main pumping organ of the body. The human heart is divided into four chambers two atria and two ventricles. The human heart consists of three layers- epicardium, myocardium, and endocardium.
The middle layer of the heart (myocardium) consists of cardiomyocytes or muscle cells. These cells receive nerve stimulation from the atrioventricular nodes and sinoatrial nodes.
What are Epithelial cells?Epithelial cells form a layer structure which covers most of the surfaces of the body. These cells perform a variety of functions and exhibit different shapes, size and arrangement which makes up different tissues. For example columnar tissues (column-like cells), cuboidal tissues (cube-like cells) and others.

Atrazine is an herbicide that prevents plant growth by inhibiting photosynthesis. Atrazine works by binding to proteins in the electron transport chain of photosystem II. Once atrazine binds to the proteins, electrons can no longer travel down the chain to reach photosystem I.
Based on this information, how does atrazine stop plant growth?
A.
It prevents water from releasing oxygen, which is needed by the light-dependent reactions to fix carbon.
B.
It prevents the formation of NADH and FADH2, which are needed by the light-independent reactions to fix carbon.
C.
It prevents chlorophyll from creating electrons, which are needed by the light-dependent reactions to make sugars.
D.
It prevents the formation of ATP and NADPH, which are needed by the light-independent reactions to make sugars.
Answers
It prevents the formation of ATP and NADPH, which are needed by the light-independent reactions to make sugars. Thus, the correct option is D.
The herbicide atrazine binds to the D1 protein and prevents plastoquinone from binding. By preventing plastoquinone from binding, the photosynthetic transport of electron is disrupted, putting the generation of ATP and NADPH in the chloroplast at risk.
What are herbicide?
Herbicides are chemicals that are used to control or manage unwanted vegetation. Herbicides are most commonly used in row-crop farming, where they are treated before or during planting to increase crop productivity while reducing other vegetation.
This results in the plant's inability to fix carbon dioxide and provide the nutrients it needs to survive. A halt in electron transmission causes oxidative stress and the generation of radicals, which leads to rapid cellular death.
