An inflatable balloon with the volume of 0.75 L at 303 K was placed inside the freezer where the temperature is 263 K. Find out what will happen to the volume of the balloon if the pressure remains constant.
Answer:
Final volume, V2 = 0.66 Litres
Explanation:
Given the following data;
Initial volume = 0.75 L
Initial temperature = 303 K
Final temperature = 263 K
To find out what will happen to the volume of the balloon if the pressure remains constant, we would use Charles' law;
Charles states that when the pressure of an ideal gas is kept constant, the volume of the gas is directly proportional to the absolute temperature of the gas.
Mathematically, Charles' law is given by the formula;
[tex] VT = K[/tex]
[tex] \frac{V_{1}}{T_{1}} = \frac{V_{2}}{T_{2}}[/tex]
Where;
V1 and V2 represents the initial and final volumes respectively.T1 and T2 represents the initial and final temperatures respectively.Making V2 as the subject formula, we have;
[tex] V_{2}= \frac{V1}{T1} * T_{2}[/tex]
[tex] V_{2}= \frac{0.75}{303} * 263 [/tex]
[tex] V_{2}= 0.0025 * 263 [/tex]
Final volume, V2 = 0.6575 ≈ 0.66 Litres

What are the functions of leaves? (Select all that apply.) PLEASE ANSWER ASAP AND GET 25 POINTS
release water vapor
absorb water and nutrients
store water and glucose
perform photosynthesis
The main function of a leaf is to produce food for the plant by photosynthesis. Chlorophyll, the substance that gives plants their characteristic green colour, absorbs light energy. The internal structure of the leaf is protected by the leaf epidermis, which is continuous with the stem epidermis.
Conifer Leaf.
Microphyll Leaf.
Megaphyll Leaf.
A leaf is an above-ground plant organ and it is green. Its main functions are photosynthesis and gas exchange. A leaf is often flat, so it absorbs the most light, and thin, so that the sunlight can get to the chloroplasts in the cells. Most leaves have stomata, which open and close.
The two main functions performed by the leaf are photosynthesis and transpiration. Photosynthesis is the process by which green plants make their food from carbon dioxide and water in the presence of sunlight.

The Big Bang is an idea that states that billions of years ago the universe began in a huge expansion of matter. This
idea has come about through numerous experiments performed by scientists including Edwin Hubble, Albert
Einstein, and Robert Wilson, all of whom revised and added to it over time The Big Bang has not yet been proven as
fact
The Big Bang can be best described as a(n)
experiment
hypothesis
theory
law
Answer:
The Big Bang theory is the prevailing cosmological model explaining the existence of the observable universe from the earliest known periods through its subsequent large-scale evolution. The model describes how the universe expanded from an initial state of high density and temperature,and offers a comprehensive explanation for a broad range of observed phenomena, including the abundance of light elements, the cosmic microwave background (CMB) radiation, and large-scale structure.
Crucially, the theory is compatible with Hubble–Lemaître law—the observation that the farther away a galaxy is, the faster it is moving away from Earth. Extrapolating this cosmic expansion backwards in time using the known laws of physics, the theory describes an increasingly concentrated cosmos preceded by a singularity in which space and time lose meaning (typically named "the Big Bang singularity"). Detailed measurements of the expansion rate of the universe place the Big Bang singularity at around 13.8 billion years ago, which is thus considered the age of the universe.
After its initial expansion, an event that is by itself often called "the Big Bang", the universe cooled sufficiently to allow the formation of subatomic particles, and later atoms. Giant clouds of these primordial elements—mostly hydrogen, with some helium and lithium—later coalesced through gravity, forming early stars and galaxies, the descendants of which are visible today. Besides these primordial building materials, astronomers observe the gravitational effects of an unknown dark matter surrounding galaxies. Most of the gravitational potential in the universe seems to be in this form, and the Big Bang theory and various observations indicate that this excess gravitational potential is not created by baryonic matter, such as normal atoms. Measurements of the redshifts of supernovae indicate that the expansion of the universe is accelerating, an observation attributed to dark energy's existence.
Georges Lemaître first noted in 1927 that an expanding universe could be traced back in time to an originating single point, which he called the "primeval atom". Edwin Hubble confirmed through analysis of galactic redshifts in 1929 that galaxies are indeed drifting apart; this is important observational evidence for an expanding universe. For several decades, the scientific community was divided between supporters of the Big Bang and the rival steady-state model which both offered explanations for the observed expansion, but the steady-state model stipulated an eternal universe in contrast to the Big Bang's finite age. In 1964, the CMB was discovered, which convinced many cosmologists that the steady-state theory was falsified, since, unlike the steady-state theory, the hot Big Bang predicted a uniform background radiation throughout the universe caused by the high temperatures and densities in the distant past. A wide range of empirical evidence strongly favors the Big Bang, which is now essentially universally accepted.

According to a famous article by Max Kleiber, the scaling of the metabolic rate or energy consumption for mammals Pmetab (measured in kcal/day) with the body mass Mb (measured in kilograms) is Pmetab=70M0.75b.
a. What is the specific metabolic rate, i.e. the metabolic rate per kilogram of body mass for the following animals?a mouse whose mass is 30g. Give your answer to three significant figures.
b. What is the specific metabolic rate, i.e. the metabolic rate per kilogram of body mass for the following animals?a cow whose mass is 300kg. Give your answer to three significant figures.
Answer:
Explanation:
Given that:
The scaling of the specific metabolic rate is:
[tex]=\dfrac{P_{metab}}{m}[/tex]
where;
[tex]P_{metab} = 70M_b^{0.75}[/tex]
[tex]=\dfrac{ 70M_b^{0.75}}{m}[/tex]
(a) For a mouse whose mass = 30 g = 0.030 kg
The specific metabolic rate [tex]=\dfrac{ 70*(0.030)^{0.75}}{(0.030)}[/tex]
= 168.197 kg
≅ 168 kg to 3 significant fig.
(a) For a cow whose mass = 300 kg
The specific metabolic rate [tex]=\dfrac{ 70*(300)^{0.75}}{(300)}[/tex]
= 16.8197 kg

Genes:
A. in plants exist only in some individuals
B. they determine the structural and functional characteristics of each individual
C. they determine only the functional characteristics of each individual
D. they determine only the characteristics structural of each individual
E. do not exist in prokaryotes
Answer:
B. They determine the structural and functional characteristics of each individual
Explanation:
Genes are present in all plants and in all prokaryotes, so answer choices A and E are incorrect. Genes are present in all living things.
Genes do determine the structural characteristics of each individual, but they also determine the functional characteristics.
Structure, which is controlled by genes, directly affects function. For example, a gene could code for a specific protein's structure, which will in turn give it a specific function.
So, the correct answer is B.

What are three techniques that can be used to show that the electron transport chain is found on the matrix side of the inner mitochondrial membrane. Select all that apply.
Answer:
Explanation:
Step 1: Generating a Proton Motive Force
The hydrogen carriers (NADH and FADH2) are oxidised and release high energy electrons and protons
The electrons are transferred to the electron transport chain, which consists of several transmembrane carrier proteins
As electrons pass through the chain, they lose energy – which is used by the chain to pump protons (H+ ions) from the matrix
The accumulation of H+ ions within the intermembrane space creates an electrochemical gradient (or a proton motive force)
Step Two: ATP Synthesis via Chemiosmosis
The proton motive force will cause H+ ions to move down their electrochemical gradient and diffuse back into matrix
This diffusion of protons is called chemiosmosis and is facilitated by the transmembrane enzyme ATP synthase
As the H+ ions move through ATP synthase they trigger the molecular rotation of the enzyme, synthesising ATP
Step Three: Reduction of Oxygen
In order for the electron transport chain to continue functioning, the de-energised electrons must be removed
Oxygen acts as the final electron acceptor, removing the de-energised electrons to prevent the chain from becoming blocked
Oxygen also binds with free protons in the matrix to form water – removing matrix protons maintains the hydrogen gradient
In the absence of oxygen, hydrogen carriers cannot transfer energised electrons to the chain and ATP production is halted

Describe the normal process of osteogenesis for compact and spongy bone using the three different types of bone cells and their functions
Answer:
Osteoblasts penetrate the disintegrating cartilage and replace it with spongy bone. This forms a primary ossification center. Ossification continues from this center toward the ends of the bones. After spongy bone is formed in the diaphysis, osteoclasts break down the newly formed bone to open up the medullary cavity.

b. The adrenal medulla secretes norepinephrine when stimulated by the sympathetic nervous system.
c. The adrenal glands are strictly nerve tissue.
d. The parasympathetic division stimulates the adrenal cortex to secrete glucocorticoids.
e. The adrenal medulla is penetrated by the fibers of the sympathetic nervous system.
Answer:
The true statements regarding the adrenal glands' relationship with the autonomic nervous system are:
a. The adrenal cortex is an extension of the parasympathetic nervous system.
c. The adrenal glands are strictly nerve tissue.
d. The parasympathetic division stimulates the adrenal cortex to secrete glucocorticoids.
e. The adrenal medulla is penetrated by the fibers of the sympathetic nervous system.
Explanation:
The levels of the central nervous system which play important roles in influencing the autonomic nervous system include cerebral cortex, hypothalamus, brain stem, and spinal cord. Usually, epinephrine (adrenaline) and norepinephrine are released into the blood stem when stress or a threat occurs. This alert serves as a warning signal and defense system. The purpose is to maintain homeostasis.
Different cell types and tissues express different sets of genes; for example, some genes are expressed primarily in the heart, others primarily in the brain, and still others primarily in the liver. This is possible because all of these cell types have ____________.
a. different sequence variants that control gene expression
b. different ordering of genes on chromosomes
c. different histone and DNA modifications
d. different sets of genes
Answer:
d.Different sets of genes.
Explanation:
A cell normally only expresses a percentage of its genes and various cell types are created by the expression of distinct gene sets. In addition, in response to changes in their environment, cells can alter the pattern of genes they express, such as signaling from neighboring cells.
